West Extension Project of Jinsha West Road: Strive to complete the main construction of the main bridge across the river at Xigang Interchange this year.

The construction of the west extension project of Jinsha West Road, a key project of provinces and cities, has been promoted step by step, and the pile foundation construction of Xigang Interchange, a key control project, has been fully rolled out, striving to complete some main bridge construction this year; The soft foundation treatment of Niu Tianyang section is also in progress, so as to gain time for completing the construction of pavement structure layer next year.

At the junction of the west extension project of Jinsha West Road and the west port section of Jinfeng Road Bridge, a large-scale interchange will be built across the Xigang River and Dagang River to realize the interconnection of different roads and directions. Since the start of construction last year, this key control project has made great progress. The trestle bridge in the river has been built and the pile foundation construction has started, creating conditions for the next main structure construction.

The construction of Xigang Interchange in the West Extension Project of Jinsha West Road is very difficult. The main line bridge with a length of about 2.6 kilometers continuously crosses Xigang Road, Xigang River and Dagang River and enters Niu Tianyang area. It is divided into three floors, which are connected with Xigang Road, Guanghua Road and Xigang Viaduct. Among them, the overpass is located in the main bridge and involves water construction, which is the key and difficult point in the project. The construction unit, China Railway Bridge Bureau, concentrated manpower and equipment, used the recent fine weather to complete the construction of nearly 400 meters underwater steel trestle and three construction platforms, and entered the stage of large-scale pile foundation construction; Part of the pier of the ramp bridge connecting the land part and Xigang viaduct has been completed.

We increase investment? The day shift and night shift continuously complete the pile foundation construction in fish ponds and rivers before the flood season. About April? Completed in May. Then enter the abutment pier column construction of the bridge substructure. By the end of 2020? The Hexi section of Xigang is basically completed. Then the east side of the west port cooperates with the demolition. Basically achieve the goal of intercommunication and communication before the 20021Asian Youth Games.

In Niu Tianyang, the west extension line of Jinsha West Road will be connected with Niu Tianyang Expressway, and municipal roads such as Tuodong Road and Aimin Road will be built to improve the road network structure in Niu Tianyang. Because most areas used to be fish ponds, the geological conditions are poor, and soft foundation treatment is needed. In order to speed up the progress of the project, the construction unit opened six working faces for simultaneous construction, ensuring that the soft foundation treatment was basically completed in the first half of this year, laying a good foundation for the subsequent pavement structure construction.

The main task in the first half of 2020 is to complete soft foundation treatment, and the task in the second half is to carry out earthwork construction? Bridge and culvert construction, as well as water supply and drainage construction, the pavement structure layer construction is planned in 20021,and finally it is necessary to realize the interconnection between Niukuai Project and Jinsha West Extension, so as to achieve the purpose of * * * completion acceptance and opening to traffic.
