Treatment method for local water gushing of foundation pit
The invention relates to a treatment method for local water gushing of a foundation pit. The specific treatment method comprises the following steps: Step 1, when the local water gushing of the foundation pit occurs, a water gushing part is subjected to overexcavation, and a layer of thick gravel is laid on the water gushing part of the foundation pit; Step 2, a water collecting sleeve and a plurality of water seepage pipes are buried, the water collecting sleeve is vertically arranged, the bottom of the water collecting sleeve is sealed, a plurality of water collecting holes are formed in the periphery of the lower part of the water collecting sleeve, the water seepage pipes are obliquely arranged, the lower end of each water seepage pipe is connected with the water collecting holes of the water collecting sleeve, the foundation pit is backfilled to the bottom elevation of a foundation bottom slab through gravel or pebbles, water flows into the water collecting sleeve through the water seepage pipes, and the water in the water collecting sleeve is pumped out through a water pump; and Step 3, after embedding is completed, foundation slab construction is started, after the whole foundation bottom slab has anti-floating capacity, threaded end covers are used for tightening the water collecting holes from the interior of the water collecting sleeve, concrete with the same strength as the bottom slab is used for filling and blocking the water collecting sleeve to an upper opening by 150 mm, then a water stop blind plate is welded and installed at the upper end, and then concrete is poured to the top.
本发明涉及一种基坑局部涌水的处理方法，具体处理方法的步骤如下：步骤一：遇到基坑局部涌水时，涌水部位进行超挖，在基坑的涌水部位敷设一层厚碎石；步骤二：埋设一个集水套管以及多个渗水管，集水套管呈竖直布置且底部封住，集水套管下部周围开设有多个集水孔，渗水管呈倾斜布置，每个渗水管的下端均与集水套管的集水孔相连，使用碎石或卵石回填基坑至基础板底标高，水通过渗水管流入集水套管内，使用水泵将集水套管内的水抽出；步骤三：埋设完成后开始基础底板施工，待整体具备抗浮能力后，使用螺纹端盖从集水套管内部拧紧集水孔，使用底板同强度的混凝土填充封堵集水套管至上口150mm，接着在上端焊接安装止水盲板，完成后使用混凝土浇灌至顶部。
