Substrate water gushing and sand gushing treatment method
The invention belongs to the technical field of building construction, and particularly relates to a substrate water gushing and sand gushing treatment method. The treatment method comprises the following steps that S1, surveying and setting out are carried out, and the position of a secondary excavation foundation pit is determined; S2, supporting piles and a waterproof curtain are constructed; S3, a foundation pit is excavated; S4, the soil surface is excavated to a preset elevation and flattened, and a submersible pump is placed to pump and drain accumulated water; S5, water and sand gushing points on the soil surface of the substrate are found out, and a water flowing pipeline is built by using bricks, so that water flowing out of the water gushing points is collected to a middle dewatering well to be discharged; S6, a formwork and plastic cloth are laid on the top faces of the bricks; S7, a water stop steel shaft is installed in the dewatering well, and a cushion layer is poured;S8 a waterproof layer is laid, and concrete is poured; and S9, the dewatering well is plugged. According to the substrate water gushing and sand gushing treatment method, the bottom surface of the foundation pit can be rapidly and effectively sealed, the harmful effect of water gushing and sand gushing of the substrate on the foundation pit is restrained to a large extent, and safe and smooth construction of a main body reinforced concrete structure is guaranteed; and the construction method is simple, low in cost and remarkable in effect.
本发明属于建筑施工技术领域，具体涉及一种基底涌水涌砂处理方法，包括以下步骤：步骤一，测量放线，确定二次开挖基坑位置；步骤二，施工支护桩及止水帷幕；步骤三，基坑开挖；步骤四，土面开挖到预定标高收平，放置潜水泵抽排积水；步骤五，在基底土面上找出涌水涌沙点，用砖砌筑流水管路，使涌水点流出的水汇集到中部降水井排除；步骤六，砖顶面上铺设模板及塑料布；步骤七，在降水井中安装止水钢井筒，浇筑垫层；步骤八，铺设防水层，浇筑混凝土；步骤九，降水井封堵。本发明能够快速有效的封闭基坑底面，较大程度上抑制基底涌水涌沙对基坑的危害作用，保证主体钢筋混凝土结构安全顺利施工。本发明所述的施工方法简单，成本低，效果显著。
