Description
Technical field
The utility model belongs to underground drainage device technical field, is specifically related to one foundation pit dewatering device among a small circle.
Background technology
When geological condition reconnoitre unclear or foundation construction dewatering measure is not in place time, foundation ditch comparatively depths often forms ponding, and next step waterproof coiled material construction cannot be operated.
Summary of the invention
The utility model is solve the technical problem causing next step waterproof coiled material construction to operate when foundation ditch has ponding compared with depths, provides one foundation pit dewatering device among a small circle.
The technical solution adopted in the utility model is as follows:
One is foundation pit dewatering device among a small circle, comprise the dewatering well being positioned at foundation ditch center, a steel sleeve is inserted with in dewatering well, the lower end of steel sleeve contacts with the bottom of dewatering well, upper end extends to the outside of dewatering well, the steel sleeve being positioned at dewatering well inside is circumferentially provided with some permeable holes, the bottom outer surface of steel sleeve is enclosed with one deck nylon cloth, gravel is filled with between the inner surface of dewatering well and the external surface of steel sleeve, steel plate for sealing water is provided with between the upper end of dewatering well and concrete cushion, steel plate for sealing water welds with the external surface of steel sleeve, water pump is provided with in steel sleeve.
The degree of depth of described dewatering well is 3m, and diameter is 300mm.
Adopt the process of the utility model precipitation: by foundation ditch central excavation dewatering well, insert a steel sleeve in dewatering well, the ponding in such foundation ditch penetrates in steel sleeve by the permeable hole on gravel, steel sleeve, is gone out by water pump finally by water pump.
Adopt the utility model to efficiently solve the long-pending water problem in local in foundation ditch, facilitate the construction of next step waterproof roll.
