Steel shell type reinforced concrete water colleting well structure of soft soil foundation pump station and construction method of steel shell type reinforced concrete water colleting well structure

Abstract

The invention discloses a steel shell type reinforced concrete water colleting well structure of a soft soil foundation pump station and a construction method of the steel shell type reinforced concrete water colleting well structure. A steel plate is adopted as a water collecting well wall outer fa ade template and meanwhile serves as a permanent water collecting well outer wall, after the watercollecting well outer wall steel template sinks, water collecting well perpendicular foundation pit excavating is conducted, after excavating is completed and a plain concrete cushion is poured, the reinforced concrete well wall on the inner side of the water colleting well outer wall steel template, a well bottom plate and a pump station bottom plate steel bar are bound synchronously, concrete synchronous pouring is conducted, and an overall structure is formed. By means of the steel shell type reinforced concrete water colleting well structure of the soft soil foundation pump station and theconstruction method of the steel shell type reinforced concrete water colleting well structure, large-area slope excavating and foundation pit water falling can be avoided, and the construction difficulty is lowered; the influences of water collecting well construction on pump station bottom plate construction are reduced, and the overall construction speed of the engineering is improved; and earth excavation and the use amount of water collecting well reinforced concrete are reduced, and the investment is saved.

Description

technical field [0001] The invention relates to a water collection well structure and a construction method of a pumping station of a water conservancy project, in particular to a steel shell type reinforced concrete water collection well structure and a construction method of a pumping station on a soft soil foundation. Background technique [0002] The water collection well of the pump station is usually arranged under the bottom plate of the pump station, close to the water inlet flow channel. Its main function is to collect the seepage water at the flange at the connection between the inlet and outlet and the flow channel and the water pump joint during the normal operation of the pump station, and to collect water during the maintenance of the pump station. The water in the flow channel and the pump body is discharged through the suction pump arranged at the bottom of the sump well. The size of the water collection well of the pumping station is mainly related to the pu...

AI Technical Summary

Problems solved by technology

[0005] (3) Slope excavation of the water collection well increases the difficulty of reinforcement configuration and concrete pouring at the slope position

[0006] (4) The water collection well has a certain impact on the construction of the bottom plate of the pumping station. The increase in the construction difficulty of the water collection well will lead to the extension of the overall construction period of the pumping station and the increase of the project cost
