AI Technical Summary
In existing technologies, groundwater is allowed to rise freely during the construction of dewatering wells, which require temporary sealing to avoid affecting the construction process. However, the lack of effective sealing measures leads to water seepage problems.
The system employs a sealed flange structure, which is welded to a steel sleeve via a steel ring. A sealing rubber gasket and screws are installed on the flange ring for fixation. Combined with water supply pipes and valves for drainage, the sealing structure is ensured to be airtight. Air pressure is controlled during the filling of the impermeable material to prevent leakage.
This achieved effective sealing of the wellhead of the dewatering well, preventing water seepage, improving the structural sealing during construction, and ensuring smooth construction.
