Description
Technical field
The utility model relates to foundation pit and Tunnel Base spring pump drainage plugging devices.
Background technique
Foundation pit and Tunnel Base partial water burst, that is, spring are a kind of typical underground water harm forms.In the hole of soft clay area
When dewatering effect is bad or breaks down, hole subsoil body is impregnated soil property by underground water and softened, and underground water is under osmotic pressure effect
Gush out to form spring outward across weak soil layer；In when excavation of foundation pit is to a certain depth, stratum covers thinning, ground for Rock Region
Head is lauched to break through thin layer or gush out to form spring from rock fracture.There are spring, the integrated grounds such as Metro Deep Excavation in substrate
Stray electrical current protection etc. be unable to satisfy realization job requirements, simultaneously because spring gush out substrate waterproof coiled material construction quality also by
It influences, influences bottom plate outsourcing waterproof construction.With the development of underground space development, the deep basal pit and tunnel of river and lake are closed on
The underground engineerings such as road are more and more, and substrate occurs that the case where spring is also more and more, become the work frequently encountered in underground engineering
Cheng Wenti.
There is the case where spring for foundation pit bottom in patent CN201406688Y, and providing one kind can be to the partial water burst of foundation pit
Act the polywater cover to shut off, limit the flow direction that intercepts water, facilitate subsequent diversion and drainage works, which includes that the whole body is sealed
It closes, the cover of bottom opening, is provided with outlet pipe on cover, cover is clasped into the water burst position on foundation pit when use, and will cover
Base soil certain depth is inserted into body bottom, and water burst is gradually assembled in mask body intracavity at this time, covers intracorporal air and is gathered in cover
Interior intercepting water enters diversion and drainage arrangement by outlet pipe.This method structure is simple, can be very good the office for solving foundation pit
Portion's burst problem, but cover intracorporal air and intercept water and cannot be completely exhausted out outside cover, and is thorough to not can be carried out at water burst
Closure.
Patent CN105155562B provides a kind of construction method for deep basal pit spring sealing, specific steps
Are as follows: a, the spring blocked in deep basal pit bottom is positioned, is set between spring and center spring around each
Set lead；B, catch pit is dug at the spring of center；C, catchment covers are made, the opening of catchment covers is provided with flange, with collection
Water cover clasps center spring, and water pump is put into inside catchment covers；D, catchment covers after the installation is completed, open water pump, by catchment covers
The water burst of interior collection is persistently extracted into outside catchment covers；E, the concreting of deep basal pit and catch pit is carried out in three steps, in third
Step concrete blocks the open end of catchment covers before pouring.This construction method passes through afflux, converges, draws water, blocking
Preferably resolve the gush problem that the deep basal pit bottom faced after the completion of the deep pit digging in area coastal or along the lake occurs.
This method catchment covers difficulty of processing is big, and steel plate consumable quantity is big, and do not consider catchment covers corrosion after bottom plate come to nothing to bottom slab stress
Adverse effect and underplate concrete, which pour, needs gradation piecemeal to carry out, and there is the shortcomings that increasing enforcement difficulty and duration.
