Rizo expressway Phase II Project-Overview

201101On October 28th, the construction of Chongli-Zhangcheng Street Section of Rizo expressway Phase II was officially started, and it is expected to be completed and opened to traffic in 20 14 years.

The first phase project from Zhangjiakou to Chongli in expressway, Rizo was completed and opened to traffic at the end of September 20 10. The second phase of Chongli-Zhangcheng Street Project in expressway, Rizo started from Chongli North Interchange, the end of the first phase project in expressway, Rizo. The route passes through Taipingzhuang and Baiqi in the north, Nanshanyao Village crosses Nanchi Highway in the west, turns northeast in Shizigou Town, crosses Huapiling in Donggou, reaches the dam, passes through Laohugou, Nobaoshan and Han Qing Dam in the north, and crosses Hulu River in Dongtan. Total length of the route101.807km. There are 4 interchanges and 4 tie lines along the whole line, with a total length of 54. 1 km. This section of highway adopts two-way four-lane construction, and the design speed is 80 km/h. The construction of this project is of great significance to improve the structure of expressway network in our province, strengthen the connection between Rizo and Rizo, promote the development of resources and tourism in the two cities, speed up the poverty alleviation in Bashang area and promote the harmonious development of regional economy.

Rizo expressway Phase II Project-Progress

2065438+On March 28th, 2003, the mobilization meeting of land requisition, demolition and engineering construction in Chongli-Zhangcheng Street, expressway, Rizo was held. Pan Xiaodong, member of the Party Committee and Deputy Director of the Department, and Song Wenling, Vice Mayor of Zhangjiakou Municipal Government attended the meeting and delivered speeches.

Pan Xiaodong emphasized that this meeting marks the official start of the second phase project of expressway, Rizo, and all levels and departments should cherish opportunities, honors and posts and play their respective roles in the project construction. In engineering construction, first, we should unify our thinking, gather strength and fight the overall war of land acquisition and demolition. Create a good government environment, social environment, public security environment and public safety environment. The second is to stick to the goal and work together to ensure that no safety and quality accidents occur. Third, adopt strict standards and procedures to ensure the implementation of construction standardization. Fourth, we must comprehensively promote the "ten openness" and strengthen the building of a clean government.

Song Wenling said that the county governments and relevant units should unite and cooperate with a high sense of historical mission and strong sense of responsibility to overcome difficulties and successfully complete the second phase of relocation in expressway, Rizo.

20 13 At 9: 56 am on April 27th, Rizo Expressway broke ground on Huapiling Tunnel from Chongli to Zhangcheng Street, marking the start of the controlled project in expressway, Rizo.

Huapiling Tunnel is located in Shuiquanwa Village, Zhanhai Township, Zhangbei County, Hebei Province. The total length of the tunnel in both directions is 3000 meters. Built by China Railway 11th Bureau Group, it is the largest control project in the whole line. The climate here is cold, and the effective construction period is only 15 to 18 months.

In order to strive for the early completion of the tunnel, the leaders of the management office ran around, worked hard day and night, and fully supported and coordinated. At the same time, the leaders of Zhangbei County and Zhanhai Township also gave active support and cooperation. The project department has done a lot of preparatory work in local coordination, construction procedures, materials and equipment, construction personnel and technical tests. The groundbreaking marks the official entry of Huapiling Tunnel into the construction stage.

On the morning of April 28th, 2065438+03, Guyuan section of Rizo Expressway, a key traffic construction project, started construction in a festive and warm atmosphere. At the construction site of Changliang Shi Lishan, salutes rang, colorful flags fluttered, and several machines started motors to work together, which was a busy scene. It is reported that the Guyuan section of expressway, Rizo is an integral part of the layout of the highway network in Hebei Province, and it is also one of the main trunk lines of the highway network construction in Guyuan County. The starting point of the route is located near Xiba Village in Lianhuatan Township, passing through Xixinying Township, Xiaohezi Township, Pingdingbao Town and Shilishan Village in Changliang Township. The total length of the route is 54.3697 kilometers and the design speed is 80 kilometers per hour. Two service areas, 1 high-rise interchange and two exit interchanges will be built, namely Xiao Nanying exit interchange and Dongxinying exit interchange. The tunnel is 438 meters long. * * * Construction of 36 large, medium and small bridges, 5 separated interchanges, 7 overpasses, 5 approach bridges, 2 ramp bridges and 95 culvert passages. The total investment of the project is about 4.5 billion yuan, and the construction period is expected to be 3 years.

According to the person in charge of the project, the owner of the project is expressway Administration Bureau of Hebei Province, and the executive owner is Zhangjiakou Management Office of Rizo, expressway City, Hebei Province. Guyuan section involves four bid sections, namely bid section D, and the bridge and tunnel company of China Communications No.1 Public Bureau won the bid; E bid, Xingtai Road and Bridge Construction Corporation won the bid; F bid, Hebei Guangtong Road and Bridge Engineering Co., Ltd. won the bid; G bid, China Railway Fifth Bureau won the bid.

The construction of Guyuan section in expressway, Rizo will play a very important role in improving the road network structure and traffic conditions, stimulating the tourism and economic development along expressway, and accelerating the leap-forward development and green rise of county economy.

"High-quality, efficient, eco-friendly". In the section from Chongli to Zhangcheng Street in Zhangjiakou, expressway, Rizo, these eight words are constantly highlighted in practice. Rizo expressway Phase II officially started construction on March 28th, 2003. In just three months, solid steps have been taken in station construction, main project, ecological protection, benefiting the people and the people, creating a harmonious atmosphere between man and nature and between people.

Rizo expressway Phase II Project-Project Construction: Standard Construction Road

Walking on the construction sidewalk, the construction site under the blue sky and white clouds is very magnificent. Director Yu Hai of Zhangjiakou Management Office in expressway City, Rizo told the reporter that the machine on the tall building is called dynamic compaction machine, which is mainly used for dynamic compaction of the foundation on the half-filled and half-dug road section. The machine is digging a pile hole, and the machine rolls it before filling it ... Walking on the sidewalk is much easier than the imagined road, just like walking on the small oil road in Tongcun. Yu Hai said that the service road was built in accordance with standardization, and unqualified ones were not accepted. Stopped at a tunnel foundation construction site, workers are installing templates, surrounded by steel pipes and protective nets, with reflective materials attached to them. There are several bulletin boards standing next to it, which clearly write the name, structure, construction director and supervisor of the structure.

Yu Hai said that construction standardization is the concept of engineering construction and a good starting point. Whether the project is done well depends on the determination and strength of standardization. The management office seized the favorable opportunity for the construction unit to enter the site, conducted standardized training, and "brainwashed" the management personnel of the construction unit and the frontline construction personnel, which fundamentally changed the extensive construction consciousness after completing the training and assessment in the past. It may not be suitable at first, but after practice, standardized construction has really improved efficiency, and the word "standardization" has entered the minds of all contractors.

The project of Bid C is located at the foot of the mountain, with electric doors, and the ground of the courtyard is hardened. Several rows of brick-wood houses are offices and staff quarters of various departments, and a large-scale meeting of colored steel plates is next to the north-south direction. Li Jun, the project manager, said that this used to be a dilapidated village committee and primary school. After we withdrew from the fields, all of them were left to the villagers to continue to use. According to the standardization requirements, the facilities of the project department have standards, such as staff bathrooms and toilets. Standardization gives front-line construction workers dignity, and they are no longer rustic after work.

It is understood that most of the seven project departments, four resident offices and 1 director's office in the whole line were rebuilt by using old local primary schools, old village committees and warehouses, and did not occupy a new acre of cultivated land. While realizing the standardization of resident offices, it is equivalent to building several "Hope Primary Schools" and "Villagers' Activity Centers" in the local area.

Yu Hai said that all single projects in the whole line will implement the first project acceptance system, establish standards, norms and procedures, and allow large-scale construction only after summing up experience, and resolutely not speed up the project progress at the expense of project quality.

Rizo expressway Phase II Project —— Protection and Greening: Ecological Road

Most of expressway, Rizo is located in the transitional zone of Bashang Plateau, where desertification is serious and the surface is very dry, covered with a layer of eluvial soil. When the wind blows, there is dust all over the sky, and everywhere the machine passes, there is a puff of smoke and dust fluttering with the wind. 3-4 sprinklers will be sent to maintain the sidewalk every day to prevent dust.

The management office requires the construction team to focus on environmental protection when entering the site, emphasizing that the project cost cannot be reduced at the expense of the ecological environment. Previously, the builder's fund for greening design was 1-2 yuan m2, which could not meet the requirements of environmental protection. Considering the fragile vegetation in Zhangjiakou, it is difficult to recover once it is destroyed. The management office changed the investment in greening funds to m2 above 20 yuan. The section crossing Guyuan Wetland was originally designed as a 900-meter subgrade. In order to protect the wetland, it is determined to bridge the bridge, and this alone will increase the investment by 59 million yuan.

During the construction of the second phase of Rizo, special attention should be paid to protection and greening while building. Pay special attention to avoid digging and filling. Different from traditional tunnels, the designed tunnels are mostly close to the foot of the mountain and enter the karst caves along the mountain to avoid digging and filling and protect the mountain. Considering the fragile ecological environment along the way, in case of filling and digging during construction, the original appearance will be restored as much as possible after restoration to protect the original vegetation. It's difficult to get materials for the A-mark subgrade, so they used their brains to replace the villagers' gravel with dredged topsoil, which not only filled the subgrade, but also made land for the villagers, achieving a win-win situation.

In the b-bid project department, I saw a small piece of land being dug out, and the plants inside were lush and lush. Ouyang Shan, project manager of Bid B, said that this is a green belt cultivated by clearing topsoil. Different from the past, all the topsoil of Rizo Phase II was not discarded, but piled together. Topsoil is mainly humus, which is used for highway slope greening and wasteland reclamation. In addition, the Huapiling Tunnel, which just broke ground in April, will make full use of waste residue to build a viewing platform.

It is understood that Rizo Phase II plans to build two observation decks. One is located in Huapiling, which is called Jiuzhaigou beyond the Great Wall. Its main peak is as high as 2 188 meters above sea level, making it the first peak on the dam. The mountains are rolling. This observation deck is set at the exit of the tunnel. At first glance, it is picturesque. Another place is located in Wuhua meadow, where there are many kinds of plants. At different times, different flowers painted this grassland, named after the five colors of flowers that bloom in summer. The setting of the observation deck is fully combined with the tourism resources with great development prospects along the way, which embodies the harmony between man and nature.

Rizo expressway Phase II Project-Benefiting the People: The Road to Getting Rich from Poverty.

There is an obvious turn in the route from Chongli to Chengde. The staff explained: "The reason for this design is mainly because there are fewer towns and villages along the straight line. The three counties of Chongli, Zhangbei and Wuyuan, which pass through the curve, are all state-level poverty-stricken counties, and each township has exports, which can effectively pull the Bashang area out of poverty. "

The temperature in Bashang area is low all the year round, and the anti-season vegetables planted by farmers are very popular, and they are exported to Japan and South Korea in large quantities every year. "The temperature here is low, and the Chinese cabbage produced in June and July has no pests and grows well!" Yin Yong, a grower who lives in Xiawopu, proudly said that he planted 13 mu of land, mainly beans, cauliflower and Chinese cabbage. Speaking of income, he shook his head helplessly. The vegetable market is unstable every year, so he can only eat by the weather. It is understood that there are still many farmers like Yin Yong, and they are looking forward to the builders in expressway, Zhang Zhuo, opening up a road for them to get rid of poverty and become rich.

Due to the scarcity of land resources, builders try to occupy less farmland when designing routes, mostly barren hills and slopes. Moreover, in the construction of the project, the barren land resources in Zhangjiakou were fully considered, and most of the topsoil was covered with waste residue to transform the wasteland and return it to the people. According to preliminary statistics, about 2000 mu of land will be built in the borrow yard and spoil yard of the second phase project.

The second phase of Rizo provides convenient traffic conditions for the development of tourism along the line, and Chongli, Zhangbei and Guyuan counties are rich in tourism resources. Lightning River, which has nourished Bashang grassland like a mother for thousands of years, is only 20 kilometers away from Rizo Phase II. In midsummer, Bashang grassland is a summer resort with blue and white flowers and birds singing. In winter, the unique scenery outside the Great Wall is a paradise for skiers. Chongli Wanlong Ski Resort is the largest natural ski resort in northern China, which is closest to Beijing and has the most complete service facilities.

Rizo expressway Phase II Project-Joint Design: High-quality and Efficient Road

Spring came very late on the 20 13 dam, and the weather has been bad since the curtain was officially opened on March 28th. In the chilly spring of April, it was snowing heavily and the temperature was cold, and it was not thawed until mid-May. Rizo builders are not afraid of difficulties, face difficulties and overcome adversity, so that the preliminary project can be carried out smoothly. Up to now, the accumulated investment of Rizo Phase II Project is 850 million yuan. Temporary facilities such as project department, mixing station and prefabrication yard have all been completed, and subgrade engineering and table clearing work are progressing smoothly.

In order to achieve the goal of high quality and high efficiency, the construction, owner, supervisor and design unit have carried out joint design. From the initial joint design to the later dynamic design, making up for the design deficiencies and defects will run through the whole construction process.

According to Guo Jingde, director of the General Office, there are 68 culvert passages/kloc-0 in Rizo Phase II Project. Because the temperature is more than 30 degrees below zero in winter and the groundwater level is higher, in the joint design stage, the management office fully considered the anti-freezing requirements of culvert foundation, designed the anti-freezing deformation of the foundation of the structure, and set the buried depth of the foundation to 30 cm below freezing point to ensure the safety of the structure during freezing and thawing.

There is a fish pond with spring water in the contract section B, which is the source of Qingshui River. When the villagers nearby heard that the subgrade of Rizo Phase II would occupy this fish pond, they were all in a hurry. The spring water in this fish pond, through the diversion tunnel, provides drinking water and irrigation water for more than 3000 people in four isolated mountain villages in Chongli and two villages in Chicheng County. Occupation of fish ponds will inevitably pollute drinking water sources and even block spring channels, resulting in water cuts in six villages. After understanding, the management office adjusted the original design through field investigation and joint design, and set up structures to cross according to the layout of spring water, thus protecting the water source.

The construction environment is harsh, the climate is cold and dry, and the terrain drop is as high as 600 meters; The effective construction period is short and tight ... There are many difficulties in the second stage of Rizo. Overtime is a common occurrence for builders, and most people go home only once every half month. Because the project has just started and there are too many things to learn and master, the management office insists on working overtime from 7: 30 to 9: 00 every night, and also sends people to inspect posts, which is dubbed "evening self-study".

However, the builders didn't complain much. In the spirit of "pursuing Excellence, being willing to contribute, striving for strength and striving for first-class", they silently promoted the construction progress, splashed ink on the beautiful dam and painted for the beauty of traffic.
