Novel negative pressure dewatering well
The invention discloses a novel negative pressure dewatering well, and relates to the technical field of constructional engineering, the novel negative pressure dewatering well comprises a well pipe, a water inlet pipe and a valve, the outer side of the well pipe is provided with a filter material, the middle of the well pipe is provided with a water outlet pipe in a penetrating manner, the lower end of the water outlet pipe is connected with a water suction pump, and the water inlet pipe is arranged on the right side in the well pipe in a penetrating manner; a vacuum meter is arranged on the left side of the upper end of the water inlet pipe. The upper end of the well pipe is closed, the water inlet pipe, the vacuum meter and the valve are arranged in a matched mode, the well pipe is filled with water, and air in the well pipe can be completely discharged, so that when water pumping and dewatering operation is conducted on the well pipe, a negative-pressure cavity is formed in the well pipe, the pressure intensity is about negative atmospheric pressure, and a pressure difference is formed between the negative-pressure cavity and the periphery of the dewatering well pipe; meanwhile, the novel negative-pressure dewatering well is simple in process, easy to operate and wide in application range, can be used for solving the dewatering problem of a common soil layer and the dewatering problem of interlayer water, and can also be applied to surge treatment of a deep foundation pit pressure-bearing water pipe.
本发明公开了一种新型负压降水井，涉及建筑工程技术领域，包括井管、进水管和阀门，所述井管的外侧设置有滤料，且井管的中部穿设有出水管，所述出水管的下端连接有抽水泵，进水管穿设于井管的内部右侧，且进水管的上端左侧设置有真空表。本发明通过将井管上端密闭，配合设置有的进水管、真空表及阀门，通过在井管内部注满水，可以将井管内部的空气全部排出，使得在对井管进行抽降水作业时，井管内形成负压空腔，压强约负的一个大气压，与降水井管周边形成压力差，从而增大抽水半径，提高抽水效率，同时该新型负压降水井工艺简单，易操作，应用范围广，可用于解决普通土层降水问题、夹层水的降水问题，也可应用于深基坑承压水管涌治理。
