1、 施工排水系統排出的水，應輸送至抽水影響半徑范圍以外，且不得破壞道路、河坡及其他構筑物，不得損害農田和影響交通。
2、 在施工排水過程中不得間斷排水，并應對排水系統加強檢查和維護。當構筑物未具備抗浮條件時，嚴禁停止排水。
3、 地質條件良好、土質均勻，且地下水位低于基坑底面高程，且挖方深度在5m以內邊坡不加支撐時，邊坡最陡坡度應符合下表的規定。
深度在5m以內的基坑邊坡的最陡坡度
"Construction of water supply and drainage structures and acceptance of" GBJ 141-90
1, the construction of water drainage system discharges should be conveying to the outside radius of the pumping effect, and shall not damage roads, river slope, and other structures, without prejudice to the farmland and the impact on traffic.
2, in the construction of the drainage process may not continuous drainage, and should strengthen the inspection and maintenance of drainage systems. When the structures did not have the anti-floating conditions, is strictly prohibited to stop the drainage.
3, good geological conditions, soil uniformity, and the water table below the pit bottom elevation, and the excavation depth of 5m within the slope without support, the slope of the steepest degree should meet the following requirements.
Pit depth within 5m of the most steep slope degree
