摘要
施工排水包括排除雨水、地表水和地下自由水三个方面。雨季施工时,地表水会流人基坑内,所以必须做好地面雨水导排工作,使其不能流入作业坑或作业槽。在开挖基坑或沟槽时,土壤的含水层常被切断,地下水将会不断地涌入基坑或沟槽内。为了保证施工的正常进行,防止边坡坍塌和地基承载力下降,必须做好基坑的降水工作。
Drainage of construction includes excluding rain water,surface water and underground freedom water three aspects.In the rainy season construction,surface water may flow into the pit,so you must do well the ground rainwater drainage work.At the time of excavation pit or trench,soil aquifer is often be cut off,and the ground water will continue to pour into foundation pits or grooves.In order to ensure the construction work and prevent slope collapse and fall of foundation bearing capacity,we must do a good job of foundation pit precipitation.
