When will the second stage drainage project (flood diversion and interception) in Datian Plain start?

The second-stage drainage project of Datian Plain (flood diversion and interception) started on 2021/212.

At the construction site of the first phase of drainage project in Datian Plain, all sections are under full load. "Since the first phase of Datian Plain Drainage Project resumed work on February 12, the construction unit has strictly implemented various epidemic prevention measures, and the project construction has progressed steadily." Zhang Chen, assistant general manager of Linhai Water Group, told the author.

The first and second phases of Datian Plain Drainage Project (Drainage Project) are systematic water conservancy projects to solve urban waterlogging in Linhai City, and also one of the "100 billion" key flood control and drainage projects in the province. While doing a good job in epidemic prevention and control, the construction unit will make every effort to ensure the orderly progress of water conservancy projects by rationally arranging construction progress nodes. At present, 96% of the first-phase drainage project in Datian Plain has been completed.

At the construction site of the second stage drainage project in Datian Plain, with the roar of the machine, the excavator is excavating the No.2 tunnel. "The shotcrete on the side of the hole has been completed, including concrete buildings. Next, we will excavate the earthwork first, and when the hole surface is ready, we can start entering the hole. " Liu Hui, site manager, told the author.

Datian Plain Drainage Phase II (Drainage Project) resumed in February 18. At present, the construction unit is increasing manpower and mechanical equipment to ensure the completion in July this year.

The opening ceremony of the first floor of No.2 tunnel of Datian Plain Drainage Phase II Project (Drainage Project) was held. Vice Mayor Jiang Feng attended the ceremony.

After nearly 22 months' efforts, the first floor of No.2 tunnel of this project was completed two months ahead of the planned construction period.

Tunnel No.2 is one of the important construction contents of the second-phase drainage project in Datian Plain, with a total length of about 2.22 kilometers, an excavation section of 256 square meters and a design flow of 425 cubic meters per second. Yang, Party Secretary, Chairman and General Manager of the Municipal Water Group, said: "In April 2020, we successfully carried out the first blasting of the entrance section of No.2 tunnel. In June165438+1October of the same year, we successfully organized and implemented the first blasting of the tunnel exit section, opened the second construction face, and started a new stage of two-way tunnel construction and three-layer excavation, which enabled the project construction to enter the' fast lane' in an all-round way. "

The reporter learned that the second stage drainage project of Datian Plain (drainage project) has a total investment of 997 million yuan, and the construction was officially started at the end of 20 19 and 12. It consists of three parts: the drainage project from Xu 'an Village to Yuting No.2 Tunnel, the drainage project of Linghumen Station and the regulation project of seven rivers in the main city. Among them, the section of No.2 tunnel is Chengmen Cave, with a clear width of 14m. The tunnel line is arranged in parallel with Xu 'an 1 tunnel which has been implemented in the first phase of Datian Plain Drainage Project. After completion, it will effectively share the flood control and drainage pressure of the first phase of the project, realize the effect of "eastward division" of upstream mountain torrents, and effectively reduce the flood control and drainage pressure of Datian plot in our city. "In the next stage, we will carry out the blasting construction of the second and third floors of No.2 tunnel to speed up the flood diversion and interception project of the second phase of drainage in Datian Plain. After the completion of the whole project, the waterlogging problem in Datian Plain will be completely solved. " Wang, Party Secretary and Director of the Municipal Water Resources Bureau, said
