On February 10, the reporter walked into the construction site of the Yinjiang Jihuai (Zhecheng section) pipeline connection, only to see that the party member service commando team composed of more than 20 workers was busy laying pipes, painting solid seams, and earthwork backfilling.
It is reported that the Yinjiang Jihuai Project is one of the 172 major water-saving water supply projects in the country, and the construction of the Zhecheng section includes the main project Qiliqiao reservoir, pumping station, pipeline paving, etc. At present, the construction of the reservoir and the pumping station has been basically completed, and the pipeline paving is underway.
At the pipeline laying site in Daqi Township, the left side of the project is close to the provincial road and the right side is adjacent to the village, and the project work surface is narrow, and the construction encounters difficulties. The engineering department decided to adopt the steel plate self-protection paving scheme to replace the traditional slope construction, and the working surface width was shortened from the original 100 meters to 9 meters.
"The paving surface of the steel plate self-protection device is 9 meters wide and 500 meters long, which has no impact on the provincial road surface in the north and the villagers' houses in the south." At present, we are rushing to catch up with the progress and strive to complete it within half a month. Cheng Weifeng, director of the Engineering Department of the fifth bid section of the Huaihuai-Zhaocheng section of the Yinjiang River, introduced.
The project involves the construction of underground pipe jacking through provincial highways and large buildings, and the engineering department sends a technical special class to the construction site to carry out research on the construction technology of prefabricated sinking wells, from steel design and production to final processing, with the participation of technical personnel, on-site docking office, ensuring the quality and progress of the project.
Duanmu Fanbin, director of the technical department of the bidding section, pointed to the H-shaped steel next to him and said: "This H-shaped steel has a length of 12 meters, and the opening parts are designed by our engineering department according to the construction needs, which can meet the technical requirements of the prefabricated sinking well construction, and is also the latest technology in the current domestic water conservancy engineering application, which can greatly reduce capital investment and shorten the construction period." ”
"During the Spring Festival, we did not rest, racing against the clock to construct. We are confident that all construction will be completed by the end of June this year. After the project is put into operation, it will allow the people of eastern Henan to drink the water of the Yangtze River and improve the quality of drinking water for the masses in the central region. Liu Xiaojiang, deputy chief engineer of the project department of the southern section of the Henan Provincial Water Conservancy First Engineering Bureau, said.
