Abstract

The invention relates to an adjustable multilayer water taking head for river water taking, and a mounting method. The adjustable multilayer water taking head for the river water taking comprises a plurality of steel pipe piles, steel corbels which are arranged at the bottoms of the steel pipe piles, a plurality of steel casing pipes which sleeve the steel pipe piles and are located on the steel corbels, and a plurality of steel sleeves which sleeve the steel pipe piles and are located at the tops of the steel pipe piles; a steel platform is together supported by the multiple steel pipe piles;a top layer water taking head is fixed to the steel platform; each steel casing pipe comprises an upper casing pipe and a lower casing pipe; a first transverse beam is mounted between every two adjacent upper casing pipes; a second transverse beam is mounted between every two adjacent lower casing pipes; a bottom layer water taking head is fixed to the second transverse beams; and a middle layerwater taking head is fixed to the first transverse beams. According to the adjustable multilayer water taking head for the river water taking, it is guaranteed that water with the surface layer sand content being relatively low can be taken by the water taking heads in different seasons, the adjustable multilayer water taking head for the river water taking adapts to change of erosion and deposition of a river, and the safety of the water taking is ensured.

Description

technical field

[0001] The invention belongs to the technical field of water supply engineering, in particular to an adjustable multi-layer water intake head for water intake from rivers and an installation method. Background technique

[0002] At present, the water sources of waterworks mostly come from rivers, and the water is taken through the water intake head, and then enters the waterworks through the water intake pipeline and the water intake pump room. Usually, the setting of the water intake head should take into account the changes in river erosion and siltation, water flow velocity, water level changes and other conditions, and try to take water with low sand content in the surface layer as much as possible, while ensuring the safety and reliability of the water intake head structure.

[0003] Water intake from rivers has the following characteristics: ① Huge fluctuations in water levels during dry seasons and flood seasons; ② High sensitivity to river channel evo...
