Closing construction method for relief wells of foundation pit
The invention discloses a closing construction method for relief wells of a foundation pit. The method includes the following steps of closing of the first to (n-1)th relief wells and closing of the nth relief well, and n is the number of the relief wells required to be closed; after construction of a main structure is completed, when the relief wells are closed, well sealing work is performed sequentially from the first relief well to the (n-1)th relief well; and after the first to (n-1)th relief wells are closed, the nth relief well is closed. According to the method, the closing construction work of the relief wells of the foundation pit is divided into two steps, so that all the relief wells in the foundation pit can be closed smoothly, no water pumps are left in the relief wells, andthe purpose of abandoning no water pumps is achieved.
本发明公开了一种基坑减压井的封闭施工方法，包括第1至第n‑1口减压井封闭和第n口减压井封闭，n为需要封闭的减压井数；主体结构施工完成后，对减压井进行封闭时，按照顺序从第1口减压井至第n‑1口减压井，依次进行封井工作；在第1至第n‑1口减压井封闭完成后，封闭第n口减压井。本发明将基坑减压井的封闭施工工作分成两步，使得基坑内的所有减压井都能顺利封闭，而且没有将水泵留置在减压井内，实现了不废置水泵的目的。
