Underground structure bottom plate waterproof construction method
The invention relates to the technical field of underground waterproof construction engineering, in particular to an underground structure bottom plate waterproof construction method. The method comprises the following steps that S1, a geotextile is laid on the bottom of a foundation pit, a part of the geotextile covers a proposed under layer area, and the other part of the geotextile is reservedoutside the proposed under layer area; S2, an under layer is constructed in the proposed under layer area; S3, a bottom plate waterproof coiled material is laid on the under layer; and S4, the part, reserved outside the proposed under layer area in advance, of the geotextile is turned to the upper portion of the bottom plate waterproof coiled material so as to completely wrap the bottom plate waterproof coiled material, and the geotextile is fixed. During construction, the bottom plate waterproof coiled material can be protected by using the geotextile, so that subsequent connection of the bottom plate waterproof coiled material and a waterproof coiled material of an underground structure main body is facilitated, a brick membrane does not need to be arranged, the partial brick membrane does not need to be removed, the manpower input is reduced, and the construction period is shortened.
本发明涉及地下防水施工工程技术领域，尤其是涉及一种地下构筑物底板防水施工方法，包括以下步骤：S1.在基坑的底部铺设土工布，所述土工布的一部分覆盖拟建垫层区域，所述土工布的另一部分预留在拟建垫层区域的外部；S2.在拟建垫层区域施工垫层；S3.在垫层上铺设底板防水卷材；S4.将事先预留在拟建垫层区域的外部的土工布翻到所述底板防水卷材的上方，以将底板防水卷材完全包裹，并对土工布进行固定。在施工时，能够利用土工布对底板防水卷材进行保护，以便于后续与地下构筑物主体的防水卷材进行连接，无需设置砖胎膜，也无需拆除部分砖胎膜，减少了人力的投入，缩短了工期。
