Embankment anti-seepage structure and construction method
The invention provides an embankment anti-seepage structure and a construction method, and relates to the technical field of embankment engineering. The construction method comprises the steps that afoundation pit for construction is excavated in the side, close to a retaining wall body, of a river bottom; an anti-seepage layer is laid along the side, close to the retaining wall body, of the foundation pit; a protective layer is laid on the outer surface of the anti-seepage layer; the foundation pit is backfilled. The embankment anti-seepage structure obtained through the construction methodis easy to construct and low in manufacturing cost, the foundation pit is excavated in the bottom, close to the retaining wall body, of a riverway, the anti-seepage layer extends to the upstream faceof the retaining wall body along the bottom of the foundation pit, meanwhile, the protective layer is laid on the outer surface of the anti-seepage layer for protection, and then the foundation pit isfilled with a backfill body; according to the embankment anti-seepage structure and the construction method, on the premise that seepage prevention is achieved, isolation of a riverway water body andan underground water body is avoided, so that ecological exchange is facilitated, and the ecological environment is protected.
本发明提供了一种堤防防渗结构及施工方法，涉及堤防工程技术领域。该施工方法包括在河底靠近挡墙本体的一侧开挖施工用的基坑；沿基坑靠近挡墙本体的一侧铺设防渗层；在防渗层外表面上铺设保护层；对基坑进行回填。通过上述施工方法得到的堤防防渗结构，施工简单，造价成本低，通过在河道在靠近挡墙本体的底部开挖有基坑，防渗层沿基坑底部延伸至挡墙本体的迎水面上，同时在防渗层的外表面上铺设有保护层进行保护，再在基坑内填设回填体，本发明在实现防渗透的前提下，避免了河道水体与地下水体的隔离，有利于生态的交换，保护了生态环境。
