Precipitation method for narrow foundation pit
The invention provides a dewatering method for a narrow foundation pit, which comprises the following steps of: when the foundation pit is excavated, excavating and building a temporary drainage ditch in a fat groove along the bottom of the fat groove; in the temporary drainage ditch, a plurality of semi-closed water collecting pits lower than the water collecting pits are built at intervals; a groove is transversely dug, a perforated water collecting pipe is placed in the groove, and the two ends of the perforated water collecting pipe are communicated with the temporary drainage ditch in the fertilizer groove; underground water in the foundation pit can flow back into the temporary drainage ditch in the foundation pit fertilizer groove through the perforated water collecting pipe and flow into the semi-closed water collecting pit through the temporary drainage ditch; a drainage pump for drainage is erected in the semi-closed sump, the drainage end of the drainage pump is communicated with a drainage ditch formed in the top of the foundation pit through a drainage pipe, accumulated water in the semi-closed sump is drained into the drainage ditch formed in the top of the foundation pit through the drainage pump, and drainage of the bottom of the foundation pit is achieved. The problem that drainage is difficult in existing narrow underground space construction is solved.
本发明提供了一种用于狭窄基坑的降水方法，该降水方法包括如下步骤：基坑开挖时，沿肥槽底部在肥槽内开挖修筑临时排水沟；在临时排水沟内，间隔修筑若干个高度低于集水坑的半封闭集水坑；横向开挖沟槽，并在沟槽内放置穿孔集水管，将穿孔集水管的两端与肥槽内的临时排水沟连通；基坑内的地下水能够通过穿孔集水管回流流入基坑肥槽内的临时排水沟中，并通过临时排水沟流入半封闭集水坑内；在半封闭集水坑内架设用于排水的排水泵，并利用排水管将排水泵的排水端与基坑顶部设置的排水沟连通，利用排水泵将半封闭集水坑内的积水，经排水管道排入基坑顶部设置的排水沟，实现基坑底部的排水，解决了现有狭小地下空间施工中排水困难的问题。
