Treatment method for water gushing and sand gushing of bottom plate of deep foundation pit of subway station
The invention discloses a treatment method for water gushing and sand gushing of a bottom plate of a deep foundation pit of a subway station, and relates to the technical field of underground deep foundation pit engineering construction. Comprising the following steps that S10, the circle center of a sleeve is aligned with the water and sand gushing position, and the sleeve is inserted into the position below a base by the depth; s20, a plurality of water suction pumps are placed in the sleeve for continuous water suction; s30, while the water pump pumps water, a concrete cover plate is poured below the base on the periphery of the sleeve; s40, after the concrete cover plate is finally set, WSS grouting is conducted on the bottom of the concrete cover plate; s50, after grouting is completed, construction is conducted immediately to form a station bottom plate cushion layer, and according to the situation fed back by construction monitoring data, if the construction requirement is met, construction continues to be conducted to form a bottom plate; and S60, after construction of the bottom plate is completed, grouting plugging is conducted on the sleeve, and after plugging is completed, a sleeve opening is plugged immediately. The construction method has the beneficial effects that the foundation pit does not need to be backfilled, the water and sand gushing position can be constructed quickly, and situation expansion is prevented.
本发明公开了一种地铁车站深基坑底板涌水涌砂的处理方法，涉及地下深基坑工程施工的技术领域；包括以下步骤：S10、将套筒的圆心对齐涌水涌砂处，将套筒插入基底以下的深度；S20、在套筒内放入多个抽水泵进行不间断抽水；S30、在抽水泵抽水的同时，在套筒周边的基底下浇注混凝土盖板；S40、混凝土盖板终凝后，在混凝土盖板底部进行WSS注浆；S50、注浆完成后立即施工做车站底板垫层，根据施工监测数据反馈情况，若符合施工要求，则继续施工做底板；S60、底板施工完之后，对套筒进行注浆封堵，封堵完成后立即对套筒口封堵。本发明的有益效果在于：无需回填基坑，可快速作出反应对涌水涌砂处进行施工，防止事态扩大。
