Dewatering well structure in foundation pit and construction method
The invention discloses a dewatering well structure in a foundation pit and a construction method. The method comprises the steps that the construction position of a dewatering well is determined through survey and setting-out in the foundation pit, and an excavation mark is made; local deep excavation is conducted in the foundation pit along the excavation mark, so that the dewatering well is formed; a protective barrel is placed in the dewatering well, and a water pump is placed in the protective barrel; gravel backfilling is conducted on the over-excavation part around the protective barrel; and the water pump is started to pump water till the water level in the foundation pit is lowered to the safe water level. According to the dewatering well structure in the foundation pit and the construction method, the construction workload of the dewatering well is greatly reduced, and the construction cost is reduced; and through cooperation of a submersible pump and the protective barrel, the effective dewatering range is reasonably enlarged, the dewatering effect is guaranteed, and the construction quality is guaranteed while the construction cost is reduced.
本发明公开了一种基坑内降水井结构及施工方法，该方法包括通过在基坑内测量放样，确定降水井的施工位置，并做好开挖标记；在所述基坑内沿所述开挖标记进行局部深挖，以形成所述降水井；在所述降水井内放入护筒，并在所述护筒内放入水泵；对所述护筒周围超挖部分进行砾石回填；打开所述水泵进行抽水，直至将所述基坑中的水位降低至安全水位。本发明极大的降低了降水井的施工工作量，节省了施工成本，通过潜水泵配合护筒，合理扩大了有效降水范围，保证降水效果，在节省施工成本的同时保证了施工质量。
