The invention relates to the technical field of building construction and provides a foundation pit drainage system and method to solve the problems that according to a traditional foundation pit drainage mode, the drainage efficiency is low, sand is likely to accumulate to block a pipe, continuous precipitation cannot be conducted in the raft concrete pouring process, and water seepage is disorderly conducted on the side wall of a foundation pit. The foundation pit drainage system comprises semi-filtering water pipes arranged on the side wall of a foundation pit, the bottom of the foundation pit and a post-cast strip, water filtering holes are formed in the upper portions of the semi-filtering water pipes, the semi-filtering water pipes are connected to a negative pressure pump through drainage pipes, the negative pressure pump is arranged in a blind well, and the blind well is connected to a sedimentation tank through a pipeline; the semi-filtering water pipes are arranged on the side wall of the foundation pit, the bottom of the foundation pit and the post-cast strip and connected to the drainage pipe, disordered leakage water is effectively organized, organized dewatering and drainage are conducted on the bottom of the foundation pit, the side wall of the foundation pit and the post-cast strip, and the water collecting efficiency is improved through the height difference and negative pressure; water is pumped and drained to the sedimentation tank through blind well dewatering, underground water is collected and utilized, and water resources are saved.
本发明涉及建筑施工技术领域，旨在解决传统的基坑排水方式存在排水效率低、易积砂堵管、筏板浇筑混凝土过程中不能持续降水、基坑侧壁无序渗水的问题，提供一种基坑排水系统及方法，基坑排水系统包括在基坑侧壁、基坑底部以及后浇带处设置的半过滤水管，所述半过滤水管的上部设有滤水孔，所述半过滤水管通过排水管连接至负压泵，所述负压泵置于盲井中，所述盲井通过管道连接至沉淀池；本发明在基坑侧壁、基坑底部以及后浇带处设置半过滤水管，并将其连接至排水管，将无序渗漏水有效组织，对基坑底部、基坑侧壁以及后浇带处进行有组织的降排水，并且利用高差及负压提高水收集效率；通过盲井降水将水抽排至沉淀池，对地下水收集利用，节约水资源。
