Description

TECHNICAL FIELD

[0001] The application provides a dewatering well wellhead protection device, and relates to the technical field of dewatering well safety protection. BACKGROUND

[0002] In recent years, more and more large underground projects are constructed, and the depth of foundation pits is deeper and deeper. With the increase of the depth of foundation pits, groundwater is more and more abundant, and the method of artificially lowering the groundwater level needs to be taken. At present, the pipe well point dewatering is widely used as a common construction method. In the pipe well dewatering construction, a sand-free cement pipe with a diameter greater than 400 mm is mainly used as a well pipe. After well forming, the well head needs to be higher than the surrounding ground. The open well head is prone to falling into sundries, causing water pump failure, poor water pumping, and being difficult to clean in the later period. In addition, the open well head also has a great safety hazard. For example, reference documents CN201310566745.X and CN202111584001.1, one is to reform the cover structure, and the other is external protection.
