The invention relates to a dewatering construction method for a foundation pit. The dewatering construction method comprises the following steps: (1) performing investigation preparation; (2) designing a dewatering well; (3) building connecting walls on the periphery of the foundation pit; (4) performing surveying and setting out; (5) performing drilling to form a hole; (6) mounting a well casing;(7) performing well washing; (8) performing dewatering; and (9) backfilling the dewatering well. According to the method, through actual construction condition and construction requirements, the structures, the positions and the number of the dewatering wells in the deep foundation pit are reasonably planned, the dewatering wells can contain underground gushing water, the interior of a deep foundation pit is kept dry, and deep foundation pit structure construction can be smoothly performed; and a water pump is used for pumping underground gushing water in the dewatering well to complete a dewatering operation, the operation is easy and convenient, the effect is good, deep foundation pit structure construction is not affected, the construction safety is enhanced, and the construction efficiency is improved.
一种基坑降水施工方法，其步骤为：(1)勘察准备；(2)降水井设计；(3)基坑周缘连墙；(4)测量放线；(5)钻进成孔；(6)井管安装；(7)洗井；(8)抽降水；(9)回填降水井。本发明通过实际施工情况和施工要求，对深基坑内的降水井的结构、位置和数量进行合理规划，所述降水井能够容纳地下涌水，使得深基坑内保持干燥，能够顺利进行深基坑结构施工；使用水泵抽出降水井内的地下涌水完成降水操作，操作简便效果好，且不影响深基坑结构施工，增强了施工的安全性，提高了施工效率。
