Basement bottom plate sump construction method capable of preventing sand gushing and water seepage
The invention provides a construction method of a basement bottom plate sump capable of preventing sand gushing and water seepage, which comprises the following steps: S1, earth excavation: excavating a foundation pit with a specified size according to construction requirements; s2, base grouting is conducted, specifically, rapid-hardening grout is adopted for grouting, and the soil body on the periphery of the foundation pit is subjected to curing treatment; s3, cushion layer construction is conducted, specifically, after elevation control piles are arranged, cushion layer concrete is poured on the foundation pit, and after vibration, strickling and press polishing are conducted; s4, waterproof construction is conducted, specifically, waterproof construction is conducted on the cushion layer and comprises the steps of pulping, brushing, inspection and maintenance; s5, construction of a protective layer: constructing the protective layer and an isolating layer on the basis of waterproof construction; s6, reinforcing steel bar binding, wherein supporting reinforcing steel bars are bound on the foundation pit; s7, a formwork is erected, and a pit side formwork is erected; and S8, concrete pouring is conducted, layered pouring is conducted, pouring is conducted while vibrating is conducted, and a final complete sump structure is formed. By means of the method, leakage and sand gushing in the construction process can be reduced, and the use efficiency and durability of the basement bottom plate foundation pit water pit can be improved.
本发明提出一种防涌砂渗水的地下室底板集水坑施工方法，包括以下步骤：S1：土方开挖，按照施工要求开挖规定尺寸的基坑；S2：基地注浆，采用速凝浆液加以灌注，对基坑四周的土体进行固化处理；S3：垫层施工，设置标高控制桩后在基坑上浇筑垫层混凝土，振捣后刮平并压光；S4：防水施工，在垫层上进行防水施工，包括制浆、涂刷、检验和养护；S5：保护层施工，在防水施工的基础上进行保护层和隔离层施工；S6：钢筋绑扎，在基坑上进行支撑钢筋的捆扎；S7：模板支设，支设坑侧模板；S8：混凝土浇筑，分层浇筑，边振捣边浇筑，形成最终完整的集水坑结构。该方法有利于减少在施工中的渗漏、涌砂，能够提升地下室底板基坑水坑使用效率和耐久性能。
