一种应用高分子量聚乙烯板的大坝防渗结构

Use dam seepage prevention structure of high molecular weight polyethylene board

Abstract

本实用新型的一种应用高分子量聚乙烯板的大坝防渗结构,将大坝基体进行常规处理;在高分子量聚乙烯板上预埋螺帽,将预埋螺帽与地脚螺栓连接,组装成高分子量聚乙烯板单元;高分子量聚乙烯板单元上的地脚螺栓的另一端贴合大坝基体上,采用热风焊枪将多个高分子量聚乙烯板无缝焊接在一起,形成高分子量聚乙烯层,在高分子量聚乙烯层和大坝基体中间浇灌水泥层,最终形成大坝防渗结构。本实用新型具有以下优点:预埋螺帽在高分子量聚乙烯板材成形时被固定在了高分子量聚乙烯板材上,与高分子量聚乙烯板材形成一体结构,螺帽的尺寸根据板材尺寸改变而变化;地脚螺栓固定在水泥层中,使高分子量聚乙烯板材与大坝的连接更加紧固,从而使大坝更加坚固。
The utility model discloses an use dam seepage prevention structure of high molecular weight polyethylene board carries out standard processing with the dam base member, pre -buried nut on the high molecular weight polyethylene board is connected pre -buried nut with rag bolt, assemble into high molecular weight polyethylene board unit, on rag bolt's on the high molecular weight polyethylene board unit the other end laminating dam base member, adopting hot -blast welder to be in the same place a plurality of high molecular weight polyethylene board pore free welded, forming the high molecular weight polyethylene layer, the watering mud layer finally forms dam seepage prevention structure in the middle of high molecular weight polyethylene layer and dam base member. The utility model has the advantages of it is following: pre -buried nut is fixed on the high molecular weight polyethylene panel when high molecular weight polyethylene panel takes shape, forms a body structure with high molecular weight polyethylene panel, and the size of nut changes and the change according to board material size, rag bolt fixes in the cement layer, makes high molecular weight polyethylene panel fasten more with being connected of dam to it is firmer to make the dam.
