Abstract
The invention relates to a pit dewatering device, which comprises a foundation pit. The pit dewatering device is characterized in that a water collection well is reserved at the bottom of the foundation pit, a steel pipe is disposed in the water collection well, through holes are distributed on the lower portion of the steel pipe, a water pump is disposed in the steel pipe, and a gravel layer is filled between the steel pipe and the water collection well. Water in the foundation pit enters the steel pipe through the through holes on the steel pipe and timely pumped out through a pumping pipe of a submersible pump or centrifugal pump, and accordingly impact of the water on normal construction is avoided.
Description
Technical field
The present invention relates to a kind of construction drainage device, particularly a kind of mine pit precipitation device.
Background technology
In infrastructure, elevator pit, sump etc. deep-cuts part, because a variety of causes ponding occurs and can't discharge, when influencing waterproof construction, need carry out draining to it and handle.
Summary of the invention
The technical problem that the present invention will solve provides a kind of mine pit precipitation device that can in time carry out draining to mine pit.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of mine pit precipitation device, comprise foundation ditch, and its innovative point is: collecting well is established in said foundation ditch bottom; Be provided with steel pipe in the said collecting well; Said steel pipe lower part is furnished with through hole, and said steel pipe is built-in with water plug, and fills boulder bed between said steel pipe and the collecting well.
Further, said water plug is the drinking-water pipe of submersible pump or centrifugal pump.
The invention has the advantages that: the water in the foundation ditch gets in the steel pipe through the through hole on the steel pipe, is in time extracted out by submersible pump or drinking-water pipe, avoids the normal construction of its influence.
Description of drawings
Fig. 1 is a mine pit precipitation apparatus structure sketch map of the present invention.
The specific embodiment
As shown in Figure 1, comprise foundation ditch 1, establish collecting well 2 in foundation ditch 1 bottom, be provided with steel pipe 3 in the collecting well 2, steel pipe 3 lower parts are furnished with through hole, and steel pipe 3 is built-in with water plug, and this water plug is the drinking-water pipe 4 of submersible pump or centrifugal pump.Between steel pipe 3 and gully-hole 2, fill boulder bed 5.
Claims (2)
1. a mine pit precipitation device comprises foundation ditch, it is characterized in that: collecting well is established in said foundation ditch bottom; Be provided with steel pipe in the said collecting well; Said steel pipe lower part is furnished with through hole, and said steel pipe is built-in with water plug, and fills boulder bed between said steel pipe and the collecting well.
2. mine pit precipitation device according to claim 1 is characterized in that: said water plug is the drinking-water pipe of submersible pump or centrifugal pump.
