In recent years, Panzhou City has vigorously implemented the construction of backbone water source projects, and a number of reservoir construction projects have been started and resumed. At present, the construction of various project sites is in full swing.
Located in Yangchang Township, Panzhou City, Houqing Reservoir resumed construction on May 18 last year, up to now, has completed the construction of diversion tunnels, the excavation of the left and right abutment slopes of the dam, the anchor spray support, the right abutment grouting flat hole excavation and other projects.
At the RCC pouring construction site of the dam body of the Houqing Reservoir, workers and machinery are going back and forth, and they are busy with construction in an orderly manner.
Because of the quality and process requirements of the project, each pouring is formed once and cannot be interrupted, and the construction party is divided into two shifts for 24 hours of uninterrupted rotation. At present, a total of 30,000 cubic meters of RCC pouring of the dam body has been completed, accounting for 30% of the total volume of the dam body.
Zhang Zhiyong, project manager of Guizhou Water Construction Engineering Co., Ltd., introduced that the total investment of the project is 160 million yuan, the total construction and installation cost is 93.47 million yuan, and the cumulative construction output value has been completed so far is 28 million yuan. The dam type is a RCC gravity dam, with a total dam height of 54 meters, and there are still 37 meters from the top of the dam to the top elevation, which is scheduled to be completed by the end of December.
Houqing Reservoir is mainly for water supply and irrigation, the normal storage level of the reservoir is 1392.00 meters, the check flood level is 1394.50 meters, the maximum dam height is 54 meters, the dam crest elevation is 1395.00 meters, and the total storage capacity is 3.04 million cubic meters. After the completion of the project, the annual water supply will be 3.508 million cubic meters, which will solve the industrial domestic water supply and coal mine industrial water supply for 3,330 people, the safe drinking water (design population) of 20,375 people in Yangchang Township and three villages, and the irrigation water of 2,904 acres of cultivated land.
Up to now, the Houqing Reservoir has completed an investment of 89.31 million yuan.
The Qingshuihe Reservoir, which resumed work at the same time as the Houqing Reservoir, has also stepped up construction in accordance with the requirements of the construction period, and has completed an investment of 79.82 million yuan.
The Zhuchang River water conveyance project, which resumed construction on March 5, has completed 34.6 meters of wellbore of the pumping station with a total height of 52 meters, completed 5.2 kilometers of 8.1 kilometers of Liu Guanxiang water transmission pipeline, and installed pipelines for 4.3 kilometers in the direction of Yingwu.
The water conveyance project of the outlet hole has started the construction of Line 2, and a third party has been entrusted to start the procedures for the temporary use of the water pipeline, and the construction unit will enter the site for construction after the completion of the processing.
The treatment of seepage in the Kahe reservoir has been effective. Invest 15.03 million yuan to implement the leakage treatment project of Kahe Reservoir, the main project (grouting ) will be completed on March 25, and the investment of 10 million yuan will be completed in 2023.
In order to ensure the quality and safety of the project, the Panzhou Municipal Water Affairs Bureau has taken strong and effective measures to strengthen the supervision of the construction project and ensure the smooth and orderly progress of the project construction.
Yang Degao, senior engineer of Panzhou Water Affairs Bureau and director of the engineering quality and safety station, said: "In the process of supervision, regular and irregular follow-up inspections are carried out on the site, and most of the time the 'four noes and two straights' are used to inspect the construction site, and a third-party quality supervision agency is hired to randomly sample the site to test the quality of the project." ”
