Background
The underground part of the project is constructed in coastal areas of China and areas with relatively low altitude and are all invaded by underground water. Under the background of deeper and deeper foundation pit construction, the construction unit inevitably touches deeper and deeper underground water from diving to confined water. Therefore, under such a large premise, the construction of the depressurization well becomes a necessary condition for foundation pit engineering. The operating platform of the depressurization well is also a necessary condition for the depressurization well to play a role.
The depressurization well must be operated at the surface level, so the arrangement position of the depressurization well is generally arranged at the periphery of the lattice column in the pit and extends to the trestle. Firstly, do benefit to the operation, secondly adjoin with the lattice column, have certain protection in the stage of digging soil and be difficult for being damaged by construction machinery, comparatively safe. However, for a large foundation pit, a foundation pit with a large span on a certain part, or a pit-in-pit, some central zones are not provided with lattice columns, and a depressurization well cannot be arranged. The pressure reduction well is disposed in a region near the periphery. If the confined water in the central zone is required to be reduced, more confined water needs to be pumped out of the peripheral depressurization well to reach the expected confined water height. And the extraction amount of the peripheral confined water is far higher than the plan. From the perspective of safety, the confined water should be lowered as required, and excessive extraction may affect the foundation pit and the periphery, sometimes even cause adverse consequences.
If the depressurization well is arranged in a central area, the operation of the depressurization well is greatly disturbed due to the absence of trestles and the absence of latticed columns.
