Construction method for preventing municipal drainage pipe network from being damaged by land subsidence
The invention relates to the technical field of subsidence prevention, and discloses a method for preventing a municipal drainage pipe network from being damaged by land subsidence. The method includes the steps that S1, a digging tool is used to chiseling holes matched with the external dimensions of a waterproof soil layer, a concrete layer and a foundation layer; S2, sand in the foundation layer, the concrete layer and the waterproof soil layer is pumped away, and broken footstones are injected into the foundation layer through a grouting opening; S3, an anti-seepage solution is injected into an upper surface layer of the foundation layer through the grouting opening; S4, a drainage pipe is installed, a grouting machine is started again, and a concrete solution is injected into the concrete layer through the grouting opening; and S5, a waterproof geomembrane is laid at the upper end of the concrete layer, namely the interior of the waterproof soil layer, and the structure of the waterproof soil layer is transformed. According to the construction method for preventing the municipal drainage pipe network from being damaged by land subsidence, the foundation layer, the concrete layer and an anti-seepage and anti-corrosion layer are additionally arranged outside the drainage pipe, so that the situation that a land subsidence phenomenon cannot occur is ensured, an overall land subsidence prevention function is good, and the service life is long.
本发明涉及防地陷技术领域，且公开了一种防止地陷对市政排水管网造成损坏的方法，包括以下步骤，S1，使用开凿工具凿出与防水土层、混凝土层以及地基层外表尺寸相适配的孔洞；S2，将地基层、混凝土层以及防水土层内部的沙土抽走，通过注浆口向地基层内部注入碎基石；S3，通过注浆口向地基层上表层注入防渗溶液；S4，安装排水管，再次启动注浆机，通过注浆口向混凝土层内部注入混凝土溶液；S5，在混凝土层的上端即防水土层内部铺设防水土工膜，对防水土层自身的结构进行改造。该一种防止地陷对市政排水管网造成损坏的施工方法，通过在排水管外部增设地基层，混凝土层以及防渗防腐蚀层，确保不会出现地陷现象，整体的防地陷功能好，使用寿命长。
