Abstract
The invention discloses a method and a device for dewatering and draining a water collecting well of a blind drain of a deep foundation pit. The method comprises the following steps: accumulated water on the outer side of the outer wall of a basement flows into a blind drain pipe below a bottom plate of the basement in a concentrated manner through a water intercepting drain; accumulated manner in the basement flows into the blind drain pipe below the bottom plate in a concentrated manner via a water releasing hole; and then the accumulated water is led to the temporary water collecting well via the blind drain pipe and drained out by using a water pump. The device is simple to construct and can be formed rapidly. By adopting the method and the device, the underground water level is effectively reduced, the practical situation that the periphery of the basement cannot be dewatered or constructed is solved, the problem of dewatering and draining after surplus water is solved, the construction of a late poured band of the outer wall of the basement is facilitated, and the problem that the construction accumulated water of the late poured band cannot be treated by using a traditional process is solved. The construction difficulty of the bottom plate of the basement is reduced, so that the construction time of the bottom plate is greatly shortened, the construction and building cost is saved, and more importantly, the safety of a protection wall of the foundation pit is guaranteed; and as the construction period of the basement is shortened, the safety of the whole foundation pit is guaranteed, and meanwhile, the safety of the surrounding buildings and the environment are guaranteed.
