Shallow drainage method for foundation pit
The invention provides a shallow drainage method for a foundation pit, and relates to the technical field of drainage. The method comprises the steps that water collecting wells are arranged at the end corners of the bottom of a foundation pit and along the edge of the inner side of the foundation pit, drainage ditches are formed between the adjacent water collecting wells, inverted filter hidden laying water collecting pipes are arranged in the drainage ditches, water filtering holes are formed in the water collecting pipes, and water in the foundation pit flows into the water collecting pipes through the water filtering holes and then is led into the water collecting wells on the two sides through the water collecting pipes. Water in the water collecting well is pumped into the water pumping pipe through the water pump and introduced into the main drainage pipe through the water pumping pipe, and water in the main drainage pipe is gathered into the water outlet pipe and discharged into the sedimentation tank through the water outlet pipe for sedimentation. According to the method, a water collecting pipe concealed laying mode is adopted, an open trench is not formed in the foundation pit, interference to construction is reduced, meanwhile, collapse or quicksand formation of the trench wall of the drainage trench is prevented, the precipitation effect is better, the precipitation efficiency is improved, and repeated utilization of water resources is achieved by arranging the sedimentation tank.
本发明提供一种基坑浅层排水方法，涉及排水技术领域。本方法包括：在基坑底部端角处以及沿基坑内侧边缘设置集水井，在相邻集水井之间开设排水沟，在排水沟内设置反滤层暗敷集水管，集水管上开设有滤水孔，使基坑中的水通过滤水孔流入集水管中，再通过集水管引入至两侧的集水井中。通过水泵将集水井中的水抽出至抽水管中，经抽水管引入至排水干管中，排水干管中的水汇聚至出水管中，经出水管排入至沉淀池中进行沉淀。本方法中采用集水管暗敷的方式，基坑内没有明沟，减少了对施工的干扰，同时防止排水沟沟壁坍塌或形成流沙，降水效果更好，提高了降水效率，并通过设置沉淀池实现了水资源的重复利用。
