Anti-seepage structure for emergency site construction and construction method of anti-seepage structure
The invention discloses an anti-seepage structure for emergency site construction and a construction method of the anti-seepage structure. The anti-seepage structure comprises a flat compacted base layer, a compacted clay layer, a composite anti-seepage layer, an upper protective layer and a fine sand cushion layer which are sequentially arranged from bottom to top; and the composite anti-seepagelayer comprises a GCL cushion and an HDPE geomembrane which are sequentially arranged from bottom to top. The construction method comprises the steps that an existing site foundation layer is compacted, and the flat compacted foundation layer is formed; clay is paved on the flat compacted base layer and compacted to form the compacted clay layer; the GCL cushion and the HDPE geomembrane are sequentially laid on the compacted clay layer to form the composite anti-seepage layer; the upper protective layer is laid on the composite anti-seepage layer; and fine sand is paved on the upper protectivelayer to form the fine sand cushion layer. According to the anti-seepage structure for emergency site construction and the construction method of the anti-seepage structure, the adopted geotechnicalmaterials are wide in source and convenient to obtain, the special requirements for raw material blending under emergency conditions such as medical treatment can be fully met, the pertinence is high,the proposed structural layer is rapid in construction and good in anti-seepage effect, and therefore the application of traditional geotechnical materials in the special anti-seepage field is further expanded.
本发明公开了一种用于应急场地建设的防渗结构及防渗结构的构建方法，防渗结构包括：自下而上依次设置的平整压实基础层、压实黏土层、复合防渗层、上保护层和细沙垫层；复合防渗层包括自下而上依次设置的GCL垫和HDPE土工膜。构建方法包括：对现有场地基础层进行压实，形成平整压实基础层；在平整压实基础层上铺设黏土并压实，形成压实黏土层；在压实黏土层上依次铺设GCL垫和HDPE土工膜，形成复合防渗层；在复合防渗层上铺设上保护层；在上保护层上铺设细沙，形成细沙垫层。本发明所采用的土工材料来源广泛，方便获得，可充分满足医疗等“应急”状况下对原材料调配的特殊需求，针对性强，且所提出的结构层施工快速，防渗效果较佳，从而进一步拓展了传统土工材料在特种防渗领域的应用。
