- Abstract:
- Because upstream logistics terminal has a security risk to the urban water source of Jiayu County, it is necessary to relocate the water intake pumping station. The optimal site selection is determined through economic comparison, and the proposed site meets the requirements of planning, shipping, flood control and environmental protection and is reliable and safe. Based on the topography, geology, scale and landscape requirements of the river beach, the lower part of the pumping house is designed as a cylinder structure, the upper part is a platform, and the roof is a double eave form. The intake pipe is 770 meters inserted into the river. The water intake head and its 110-meter adjacent part are fixed and supported by steel pipe piles and precast steel platforms, and connected with flange to ensure the quality and safety of water intake and also adapt to the changes of the river bed. The sinking well, sinking pipe, pipe jacking, underwater steel pipe pile and precast steel platform underwater installation technology and a variety of large professional construction equipments were used in the construction. Due to the complex and changeable construction conditions, each process is mutually restricted and alternated. At present, the project has been completed and operated, and the reliability of water intake and the safety of facilities have been verified in dry seasons and flood seasons.
