Ditch structure body structure of fixed slope geomembrane and installation method of ditch structure body structure
The invention belongs to the technical field of geomembrane sealing, and particularly relates to a ditch structure of a fixed slope geomembrane and a mounting method of the ditch structure. The ditch structure body structure comprises a ditch body composed of a ditch bottom plate, a drop step and a breast board groove, and a fixing block body used for fixing the geomembrane. During installation, the ditch body is firstly fixed in a gutter, then the geomembrane is fixed, and the fixing blocks are poured to enable the geomembrane and the ditch structure to form a tight anti-seepage structure. The ditch structure provided by the invention is particularly suitable for mining operation of non-ferrous metal mines, acidic water enters a water surface line of an acidic reservoir through the ditch structure, direct scouring of the acidic water flow carrying silt to a geomembrane at the bottom of the reservoir is slowed down, and a permeation blocking whole is formed by the ditch structure and the geomembrane; and the problems of instability and deep soil pollution caused by acidic water permeation to the dam body of the reservoir can be prevented.
本发明属于土工膜封固技术领域，具体涉及一种固定斜坡面土工膜的水沟构体结构及其安装方法。水沟构体结构包括水沟底板、跌水踏步和栏板槽组成的水沟本体，和用于固定土工膜的固定块体。安装时，先将水沟本体固定在引水沟内，再固定土工膜，并浇筑固定块体使土工膜与水沟构体结构形成紧密的防渗结构。本发明提供的水沟构体结构尤其适用于有色金属矿山开采作业，通过水沟构体结构将酸性水进入酸性水库的水面线，减缓酸性水流携裹泥沙对库底土工膜的直接冲刷，与土工膜形成的阻隔渗透整体，可以防止酸性水渗透对水库坝体造成的失稳和深层土壤污染问题。
