Device for preventing basement from floating upwards through well point replacement and construction method
The invention provides a device for preventing a basement from floating upwards through well point replacement and a construction method. The device comprises a plurality of light well points arranged below a cushion layer of a foundation pit, the plurality of light well points are all connected with a main pipe, the main pipe is connected with an external main pipe, and the external main pipe is connected with a vacuum pump; before concrete is poured into a basement bottom plate, a tube well is closed, the light well points are used for continuously conducting dewatering operation on the foundation pit, the hidden danger of leakage possibly generated when the tube well penetrates through the bottom plate is eliminated, and the occurrence of basement floating accidents is eliminated; and meanwhile, after a post-pouring belt is closed, due to the fact that no reserved tube well penetrating through the bottom plate exists, basement decoration work can be immediately and comprehensively carried out, the construction period is shortened, and cost is saved.
本发明提供一种井点置换防止地下室上浮的装置及施工方法,装置包括多个设置在基坑的垫层下方的轻型井点,多个多数轻型井点均与总管连接,所述总管与外连总管连接,所述外连总管与真空泵连接，在地下室底板浇筑混凝土前封闭管井，使用轻型井点持续对基坑进行降水作业，消除管井穿越底板可能产生的渗漏隐患，消除了地下室上浮事故的发生，同时，在后浇带封闭之后，由于没有需要保留的穿越底板的管井，可立即全面开展地下室的装修工作，加快工期，节约成本。
