Pump station structure and pump station water in-out method

Abstract

The invention discloses a pump station structure and a pump station water in-out method. The pump station structure comprises a pump room body and water pump units, the pump room body is sequentially provided with a water inlet bottom layer, a water collecting middle layer and an electromechanical control top layer from bottom to top, a water inlet and a water distribution opening are formed in the water inlet bottom layer, and the water distribution opening is formed in a base plate of the water collecting middle layer in a through mode; water inlet pipes of the water pump units are arranged in the water collecting middle layer, water outlet pressure wells are arranged on the outer side of the periphery of the water collecting middle layer, and water flow is lifted by the water pump units to be guided into the water outlet pressure wells to be output outwards after entering the water collecting middle layer from the water inlet bottom layer. The pump room body of the pump station structure is divided into three layers, bottom center water distribution is achieved through the water inlet bottom layer and the water distribution opening, the upper portion peripheral water outlet is achieved in the mode that the water collecting middle layer is matched with the multiple water pump units and the water outlet pressure wells, and the problems of being large in floor space, limited in land utilization, small in pup station water inlet and water outlet pipe angle and the like are solved.

Description

technical field [0001] The invention relates to the technical field of pump station rectification, in particular to a pump station structure and a pump station water inlet and outlet method. Background technique [0002] The main structures of the pumping station from water inlet to water outlet include: water inlet box culvert, grid well, water inlet gradual expansion pipe, pump house sump well, water outlet high gate well and water outlet gradual expansion pipe. The most ideal water inlet method of the pumping station is : On the plane, the water inlet pipe and the water outlet pipe go straight in and out, and finally discharge into the river or downstream pipes; vertically, the elevation of each structure is gradually reduced, and the deepest part is raised at one time. In actual engineering, the narrow land is not enough to arrange the general plane of the pumping station according to the conventional design. First, if all the underground structures of the pumping stati...

AI Technical Summary

Problems solved by technology

First, if all the underground structures of the pumping station are tiled, plus the layout of pumping station roads, greening, management rooms, power distribution rooms, etc., the entire pumping station will occupy a very large area

Second, if the angle between the center line of the pump station inlet tank culvert and the center line of the pump station outlet tank culvert is too small, it is easy to cause the water flow to flow in the inlet gradual expansion pipe, the sump of the pump room or the outlet water gradual expansion pipe with a large inertia. A strong flow along the outer wall is formed in a certain structure, resulting in an unstable flow state, which will form a vortex funnel, affecting the normal and safe operation of the pumping station

Coupled with a series of factors such as the location requirements of some structures controlled by the environmental impact assessment, the construction safety distance of the existing surrounding buildings, and the limited land use of the pumping station, the existing pumping station structure and the water inlet and outlet methods of the pumping station cannot meet the conditions of the above-mentioned various unfavorable factors. , to implement and apply
