Underground buoyancy type lift water retaining structure

Abstract

The present application relates to water retaining structure technical field, and disclose a kind of underground buoyancy type lifting water retaining structure, including shell, the lower part of the shell outside is equipped with with its communication drain pipe, the top of the shell is equipped with the filter assembly for filtering silt.The present application can realize the close adherence of the water retaining plate to its when retaining water bag body, so that the sealing is strong, and better water retaining is carried out, and the impurity particles adhered to the surface of bag body can be cleaned during the process of water retaining plate rising, so that the surface of bag body remains clean, avoid impurity particles affect the close adherence of bag body when expanding with water retaining plate, so that water retaining plate and bag body better close adherence, positioning assembly can be used to realize the positioning of water retaining plate, so that it more stably retains water, and water retaining plate can be selected to be lifted by using the buoyancy of water or electric mode, convenient to use, and when using electric mode, the response speed of water retaining plate rising is faster.
