Double wing type plastic soft belt type one-way automatic drainer

Abstract

The invention discloses a double wing type plastic soft belt type one-way automatic drainer. The drainer comprises an outer sleeve, wherein an upper closing plate and a lower closing plate are arranged in the lower part in the outer sleeve at an interval; water inlet holes are formed on the upper closing plate, the lower closing plate and the side wall of the outer sleeve between the upper closing plate and the lower closing plate; a filter material is arranged in the outer sleeve between the upper closing plate and the lower closing plate; the lower end of an inner sleeve is inserted into the outer sleeve, the lower end face of the inner sleeve props against the upper surface of the upper closing plate, the upper end of the inner sleeve is connected to one end of an elbow, and the other end of the elbow is connected to one end of a double wing type plastic soft belt through a plastic soft hard pipe connector. By adopting the technical scheme, the drainer disclosed by the invention is reasonable in structural design, and not only can automatically and immediately drain underground water to alleviate the pressure of the underground water so as to effectively solve the problem that the underground water damages uplift pressure jacking of a channel or a plain reservoir impermeable layer, but also avoids reverse osmosis of water in the channel (reservoir), thereby providing an effective guarantee to safe operation of the impermeable channel or the plain reservoir.

Description

Technical field: [0001] The invention relates to a two-wing type rubber and plastic soft belt type one-way automatic drainer. Background technique: [0002] At present, there are many anti-seepage forms used in the construction of canals and plain reservoirs. In order to reduce seepage loss, lower the groundwater level, and prevent secondary salinization of soil, anti-seepage technical measures of various structures and materials are widely used in different regions. However, due to the relative impermeability of the anti-seepage material, especially the composite structure anti-seepage body mainly composed of geomembrane, the anti-seepage body can effectively prevent leakage and also hinder the removal of groundwater, resulting in the effect on the bottom and slope surface. When the groundwater level is higher than the water level of the channel or plain reservoir due to rainfall in the flood season and other reasons, external water pressure is formed, and cracking and dama...

However, due to the relative impermeability of the anti-seepage material, especially the composite structure anti-seepage body mainly composed of geomembrane, the anti-seepage body can effectively prevent leakage and also hinder the removal of groundwater, resulting in the effect on the bottom and slope surface. When the groundwater level is higher than the water level of the channel or plain reservoir due to rainfall in the flood season and other reasons, external water pressure is formed, and cracking and damage are easily occurred in the weak part of the anti-seepage body, and even large-scale and large-scale landslide collapses occur Phenomenon
