The model essay of the practice report of water conservancy and hydropower is 3500 words.

Just after my sophomore year, the school organized us to go to the reservoir to do an internship in reservoir understanding. Although our professional courses have not been offered, there is no theoretical basis and no practical experience, but this kind of understanding practice is very valuable to me. I compiled a 3500-word model essay internship report on water conservancy and hydropower for your reference only. More articles are available.

As learners of water conservancy, hydropower and electrical engineering, we will shoulder the historical responsibility of the motherland in the near future and create great achievements for the water conservancy cause of the motherland. The task of our water conservancy workers is to prevent floods, reduce and alleviate the swallowing of people's lives and property and the aggravation of national economic losses. In addition, we should make full use of hydropower and water resources to ensure the safety of people's lives and improve their living standards, thus improving our national economy. To this end, we need to know about water and water conservancy buildings.

Just after my sophomore year, the school organized us to go to the reservoir to do an internship in reservoir understanding. Although our specialized courses have not been offered, there is no theoretical basis and no practical experience, but this kind of understanding practice is very valuable to me. The purpose of reservoir understanding practice is to let us have a profound understanding of water conservancy projects, understand our own tasks and necessary knowledge, and initially make us have a perceptual understanding of the main buildings and equipment of hydraulic structures, so as to lay the foundation for our future professional courses.

Our practice of reservoir knowledge lasted for one week on a regular basis and officially kicked off on July 16 of the summer vacation. Nearly 300 people from 4 classes of undergraduate and 6 classes of junior college majoring in hydraulic engineering *** 10 visited Shangkou Reservoir, Dongwushi Reservoir and Yuecheng Reservoir under the guidance of many practice instructors such as Mr. Mu, a counselor. Through this internship, I have a further understanding of the reservoir. It can be said that it is formed by crossing a dam on the tributary or main stream of a river, so that the upstream water is stored and the downstream water is cut off. Of course, there are also certain technical design requirements for dams, such as the type of dams, whether to build earth-rock dams, masonry gravity dams or concrete dams. These choices will take into account many factors, such as the height and width of the dam, the design of the dam shape, and the matching outlet buildings (spillway, spillway tunnel, power generation tunnel) and power station.

After the reservoir is completed, it will have a certain storage capacity, and different reservoirs can accommodate different amounts of water according to their own design and environmental requirements. Therefore, according to the size of the reservoir capacity, the reservoir can be divided into the following grades:

Reservoir type Reservoir capacity

Small reservoir: small (II) type10-100000 cubic meters.

Small (I) type100-1100,000 cubic meters

Medium-sized reservoirs are 6.5438+million cubic meters-6.5438+million cubic meters.

Large reservoirs: large (II) type 1 100 million cubic meters-1 100 million cubic meters.

Large (I) type is greater than 1 100 million cubic meters.

Reservoir construction plays an important role, mainly in the following aspects.

1. Flood control, whether it is a small reservoir or a large reservoir, takes flood control as the primary role. Interception of water flow and prevention of huge loss of life and property caused by flood discharge in flood season have played an indirect role in creating value.

2. Sea transportation Among air, land and sea transportation, water transportation is the cheapest and necessary in some places. The construction of small reservoirs does not have this function, while some large reservoirs (such as the Three Gorges Reservoir) have navigation function.

3. The development of tourist reservoir can develop a tourist attraction according to its own conditions and surrounding environment to attract tourists from all over the world. The matching of motorboats and boats, the development of swimming areas and the development of tourist resorts can all promote the economic development of one side.

4. In addition to indirectly creating wealth, power generation reservoirs can also directly create value through power generation. Hydropower uses water energy, which is a kind of natural gas energy and pollution-free. By converting water energy into electric energy, the water quantity is not reduced, and the utilization of water energy can be recycled, especially in the development of cascade reservoirs on rivers. Hydroelectric power generation accounts for 20%-30% of the total power generation in China. Although it accounts for a small proportion in nuclear power generation, it has little pollution and almost no pollution, so its development prospect is considerable.

5. Industrial and agricultural water supply and aquatic farmland irrigation. Reservoirs can solve this problem. When the weather is dry, the water stored in the upstream can be introduced into the ditch through the outlet hole to guide farmland irrigation and help increase agricultural production and value. China is a big agricultural country, and cultivated land occupies a certain area. Irrigation is an indispensable measure. With the development of industry, industrial water consumption is also increasing greatly. The reservoir will provide long-term water storage to major industrial departments according to certain indicators, so that they can operate normally and create national income. The fish sideline business near the reservoir has also developed very well, which has increased some economic income for local residents and relatively reduced the government's economic payment burden to farmers.

The above is my general understanding in the process of internship, and I understand the value of water conservancy to the country and people and its indelible role. Next, I will briefly summarize the information of the three reservoirs we practiced.

Yikoukou Reservoir

Shangkou Reservoir is located at the intersection of Shechuan and Daomenchuan in the upper reaches of Beiming River in Wu 'an City, also known as Jingniang Lake. It is 32km from Wu 'an in the southeast and 60km from Handan in the east. Completed from 1966 to 1969. The maximum water surface is more than 2,500 mu, the storage capacity is 32 million cubic meters, and the maximum water depth is more than 50 meters. The reservoir dam is a masonry gravity dam, and there are working bridges (convenient for construction and staff to design and maintain the dam) and traffic bridges (connecting the left and right banks for convenient transportation) on the dam. The left and right sides of the dam are made of solid masonry materials, with a spillway tunnel in the middle and five openings for flood discharge in flood season. The downstream of the dam is designed as an arc to reduce the impact of hydraulic power on the dam and avoid self-destruction. There is a water inlet near the right bank at the upstream of the dam, which is buried below the water surface, so that the water can enter the corresponding downstream power station for hydropower generation.

The total installed capacity of Shangkou Reservoir Power Station is1120 kW (1800+1320), and horizontal hydrogenerator is adopted. The power station machine room is equipped with a crane with a lifting weight of 10T, and the crane is equipped with a hook. The crown block can move on the upstream and downstream top beams, which is convenient for the installation, maintenance and replacement of indoor equipment.

Shangkou Reservoir also takes into account the farmland and industrial water nearby. In addition, because of its good water quality, it has become a good place for tourists to spend their holidays.

Eryuecheng Reservoir

Yuecheng Reservoir is located at the junction of Cixian County in Hebei Province and Anyang County in Henan Province. It is a large-scale water conservancy project on the Zhanghe River, mainly for flood control. The reservoir started construction in 1958, stopped flood in 1960, stored water in 196 1 year and was completed in 1970. Control the basin area 18 100 square kilometers and the reservoir capacity 109 billion cubic meters. 1987~ 199 1 Carry out the dam heightening and reinforcement project again. At present, the total storage capacity of the reservoir has reached 654.38+03 billion cubic meters, and the design flood control standard has reached 1000. This reservoir can irrigate more than 2.2 million mu of farmland.

The reservoir dam is a homogeneous RCC dam. A main dam and four auxiliary dams form an earth dam, with a total length of 6294.5 meters and a maximum dam height of 55.5 meters. A major feature of the dam is the spillway tunnel (culvert) under the dam.

The spillway tunnel is buried under the dam and located on the left bank of the main dam. It consists of three parts: intake tower, tunnel body and outlet energy dissipation section. It has 9 holes with a diameter of 810m. Except for the right hole, the other 8 holes are all used for flood discharge, and the maximum flood discharge is 3530 cubic meters per second.

The spillway is located between the main dam and the auxiliary dam. This is a spillway with steep grooves. The entrance gate has 9 holes and adopts three-stage underflow energy dissipation. Maximum flow 12820 cubic meters per second.

The hydropower station is located on the right side of the stilling basin of the spillway tunnel. The right tunnel of the spillway tunnel is equipped with 5-meter-diameter and 280-meter-long penstock for water diversion and power generation, with a total installed capacity of 1.7 million kilowatts.

Yuecheng Reservoir is a large reservoir. Its large reservoir capacity and large power generation provide hydropower energy for people's lives in Handan and Anyang, and make great contributions to creating national economic income.

Wushi Reservoir in Shandong Province

Dongwushi Reservoir is located in Cixian County, 30 kilometers southwest of Handan City, on the upper reaches of Fuyang River. 1958 1 month,1August, 959. It is a comprehensive utilization project for flood control, irrigation, power generation and fish farming. At first, the total storage capacity was only 64 million cubic meters. Later, due to the low flood control standard and more abandoned water, it could not meet the demand of industrial and agricultural water and could not play a greater role. So the second expansion was carried out at 1970, and the main project was completed at 1975. The storage capacity of the reservoir has reached 65.438+0.52 billion cubic meters, which is a large (II) type reservoir, with the maximum flood discharge of 825 cubic meters per second, the normal storage area of 25,864 mu, the irrigation area of 546,000 mu, and the annual irrigation water consumption of 3910.7 million cubic meters. Undertake the water supply task of Handan City, with an annual water supply of 6.5438+0.42 million cubic meters. There is a hydropower station downstream of the reservoir, with an annual output of190,000 kwh. 1993~ 1999, Dongwushi Reservoir was reinforced again. At present, it is a large-scale (2) comprehensive water control project which focuses on flood control and water supply, taking into account irrigation and power generation. The total storage capacity of the reservoir reaches 1.8 1 100 million cubic meters, the design flood standard reaches 1.000, and the check flood standard reaches 1000. The reservoir dam is a homogeneous roller compacted earth dam, with a masonry breakwater upstream. The upstream of the dam is dry masonry slope protection, and the downstream is pebble and turf slope protection. The total length of the dam is 2,874 meters, the maximum dam height is 34. 1 m, and the width of the dam crest is 6.0 meters. There is an emergency spillway on the left bank of the reservoir, which is an open channel.

The spillway tunnel is located on the right bank of the main channel in the middle of the dam, with a total of ***3 holes. The entrance adopts arc steel gate, and the intake tower is a closed shaft. There are 1 plane access doors and 3 arc working doors in the tower, and a hydraulic hoist system is installed. The power generation tunnel is a circular pressure tunnel with ***2 holes. The intake tower is a closed shaft, and there are two flat steel gates and two concrete maintenance gates in the tower.

The power station is located upstream of the dam. The power station is divided into two workshops, the main workshop and the auxiliary workshop. * * * There are two installed machines with an installed capacity of 6,400 kilowatts (23,200). The power station system is complicated in setup and strict in operation procedures. The annual output of the reservoir power station is190,000 kwh, which is used by residents and industrial production in Handan.

In July 19, the practice of reservoir knowledge was successfully concluded. This is a valuable internship for our students. By visiting the construction and use of three reservoirs and listening carefully to the patient and responsible explanations of reservoir managers, I have a general understanding of reservoirs, which will affect my future study of this professional course. The understanding of theoretical knowledge will be deeper and the learning direction of navigation will be clearer.
