Depressurization tube well structure
The invention provides a depressurization tube well structure, and aims to solve the problems of poor stability of a water filtering effect and over-high sand content of outlet water of a current downcast tube well by utilizing a filter tube and gravel, the water filtering of the downcast tube well is realized through a multi-stage filter tube, the instability of sand filling quality is avoided, fine particles in underground water can be precipitated in a middle cavity of the filter tube, the sand content is reduced, and the service life of the downcast tube well is prolonged. And the water filtering performance, the water outlet efficiency and the long-term operation efficiency of the dewatering well can be effectively improved. And compared with sand filling operation, the direct lifting construction of the multi-stage filter pipe improves the industrialization degree of downcast pipe well construction, accelerates the construction speed and improves the construction quality of the downcast pipe well at the same time. The dewatering tube well is suitable for being arranged as a dewatering tube well during underground water pumping operation in geotechnical engineering, especially confined water lowering operation in foundation pit engineering.
本发明提供了一种降压管井结构,针对当前降水管井利用滤管和砂砾滤水效果稳定性不佳，出水含砂率过高的问题，本发明降水管井滤水通过多级滤管实现，避免填砂质量不稳定性，滤管中间空腔能沉淀地下水中细小颗粒，降低含砂率，进行可以有效提高降水井的滤水性能、出水效率和长期运行效能。多级滤管直接吊放施工，相较于填砂操作，提高了降水管井施工的工业化程度，加快施工速度的同时，提高降水管井的施工质量。适用于岩土工程中抽取地下水作业时设置作为降水管井，尤其是基坑工程中降承压水作业。
