Geomembrane core wall bank slope weir foundation lap joint construction method
A geomembrane core wall bank slope weir foundation lap joint construction method comprises the following steps that S1, cover plate concrete pouring construction is conducted, and a mounting groove is reserved; s2, geomembrane installation and construction; s3, second-stage concrete is poured; s4, clay material filling; the second-stage concrete is arranged, on one hand, the surrounding seepage length of the contact face of the geomembrane and the cover plate concrete is increased, the seepage prevention effect is improved, meanwhile, the lap joint position of the geomembrane is filled with clay, tearing of lap joint of the geomembrane caused by uneven settlement of the weir body is prevented, the geomembrane is protected again, and the service life of the geomembrane is prolonged. According to the method, the problem of lap joint and fixation of two different materials is solved, the problems of leakage, tearing and the like during lap joint of the geomembrane core wall bank slope batholith can be effectively avoided, and the method is simple in structure, convenient to construct, high in universality and capable of being popularized and applied to the field of lap joint construction of the geomembrane core wall bank slope weir foundation.
一种土工膜心墙岸坡堰基基础搭接施工方法,包括以下步骤：S1、盖板混凝土浇筑施工，预留安装槽；S2、土工膜安装施工；S3、浇筑二期混凝土；S4、粘土料填筑；本发明设置二期混凝土一方面增加了土工膜与盖板混凝土接触面的绕渗长度，提升防渗效果，同时在土工膜搭接位置填筑粘土，防止堰体不均匀沉降导致土工膜搭接的撕裂，再次对土工膜进行保护，本方法解决了两种不同材料的搭接固定问题，可以有效避免土工膜心墙岸坡岩基搭接时出现渗漏、撕裂等问题，结构简单，施工便捷，具备较强的通用性，可以推广应用到土工膜心墙岸坡堰基基础搭接施工领域。
