Based on rock, volcano lava, fractured zones that groundwater occurrence is developed in joint, structural fracture, weathering fissures and separation fracture.One
As 2~3 millimeters of Fracture Width, 10~20 millimeters of big person, long number rice to more than ten rice, average 1~2 meter has a crack, underground water
Opposite to be enriched in north-south, NW trending extensional or the property turned round crack, based on diving, fractured zones locally have veiny pressure-bearing
Water.Bedrock Crevice Water is fed by Atmospheric precipitation, and interflow subsurface drainage is short, is often discharged into the form of spring in neighbouring cheuch.And it is directed to
Bedrock Crevice Water, if being unable to reach desired effect, serious shadow according to traditional well-points dewatering mode during foundation pit construction
Ring construction speed.
Utility model content
The utility model aim is to provide deep basal pit crevice water exhaust device, to solve existing drainage of foundation pit inefficiency
The problem of.
The utility model is achieved through the following technical solutions：
Deep basal pit crevice water exhaust device, including discharge guiding pipe, water pump and the steel deck-plate that catch pit is completely covered, water pump
It is placed in catch pit, and the water outlet of water pump is connected to discharge guiding pipe lower end, steel pipe is equipped on the steel deck-plate, and in steel
The through-hole coaxial with steel pipe is provided on cover board, the upper end activity of discharge guiding pipe continues to prolong outward through through-hole and after entering in steel pipe
It stretches, and is equipped with the protrusion of annular on the ontology epimere outer wall of water pump, and hingedly set by torsional spring on the inner peripheral wall of through-hole
Multiple rubber slabs are equipped with, further include snap ring, the free end of multiple rubber slabs is hinged with the outer circle wall of the snap ring, described
The internal diameter of snap ring is H, and the outer diameter of water pump is L, and the outer diameter of protrusion is K, and meets L ＜ H ＜ K；In use, the lower end activity of water pump
It is moved to the bottom of catch pit after snap ring, behind snap ring upper surface and the contact of the lower surface of the protrusion, under water pump stops
It moves.In the prior art, when mountainous region or hills location carry out deep pit digging, it will usually encounter the underground water in rock fracture
Exudation needs that catch pit progress drainage sunk well is arranged, traditional well-points dewatering mode refers to before excavation of foundation pit, in foundation pit four
Week buries a certain number of filter pipes, is drawn water using pumping equipment, ensures that dug soil remains drying regime, but real
It tramples and shows that the drainage effect of such mode is very undesirable, since the exudation of crevice water before excavation of foundation pit is unevenly distributed, and ooze
Output differs, i.e., the pump drainage in multiple filter pipes is relatively inefficient, can not ensure that the water content in institute's shoveling earth is maintained at one
There are still crevice waters to ooze out under a lower range level, and after excavation of foundation pit process, in deep basal pit, influences to build
The progress of construction；In this regard, pump drainage mode of the applicant in abandoning tradition well-points dewatering, the most direct Pit Excavation Methods of use,
I.e. first so that catch pit molding, is then arranged steel deck-plate in catch pit upper surface, so that catch pit is closed, on steel deck-plate admittedly
Determine steel pipe, and through-hole is set for being connected to steel duct on steel deck-plate, stablizes relatively at this point, forming one in deep basal pit
Polywater channel, by water pump by below steel pipe and through-hole in plash, then by discharge guiding pipe by splitting in catch pit
Gap water is quickly outer to be arranged, and at this time due to the water constant in catch pit, and the exudation rate of crevice water is relative to outer row's rate
It is relatively low, but can ensure under the premise of water pump is realized and maximizes power, to ensure the antecedent soil moisture in deep basal pit, to avoid
