Description
Technical field
The utility model relates to a kind of waterproofing system, relates in particular to a kind of sole plate waterproofing system of building.
Background technology
Usually, during the building construction subterranean layer, in the inside of underground bottom position building, can assemble from sole plate below and the outside water that generates of building.Existing common way is to form interior waterproof job practicess such as ground mortar waterproofing course, metope mortar waterproofing course, SBS complex waterproof layer at interior of building, even but take all waterproof measures, before the unresolved root problem, infiltration also can appear in inside.So, be necessary to take essential measure, solve the water that sole plate bottom and wall generate, thereby obtain stable waterproof effect, improve utilization rate, the building service efficiency of the underground space.
Excavation surface connects splash guard (auxiliary adrainage material) or tubing (main adrainage material) formation draining road below sole plate, be the drainage effect of avoiding sandy soil to flow into, keep clear, main adrainage material and auxiliary adrainage material are connected to collecting well, thereby obtain the solution of essence waterproofing work effect; In addition, building periphery and bottom are if there is a large amount of underground water, and because underground water can conduct buoyancy, the stability of building and safety will be on the hazard.And if force the underground water of quick excessive discharge building periphery and bottom, former water space causes land subsidence because of empty suddenly, and building settlement causes potential safety hazard.So, be necessary to set up a cover waterproofing system, need not excessive discharge underground water, and can solve the percolating water that flow under the buoyancy effect above the ground concrete layer.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and a kind of building foundation base plate waterproofing system is provided, and it effectively improves basement ground waterproof effect.
For achieving the above object, the utility model adopts following technical scheme: it comprises discharge pipe line, collecting well, discharge pipe line is arranged between the base concrete layer and ground of building, collecting well is arranged on a side of base concrete layer and the grout blanket of building, and discharge pipe line is communicated with collecting well.
At first, between building foundation layer of concrete and ground, the road that fixes a drainpipe is induced to the collecting well place to underground water; Swan-neck is installed then, the underground water that blocking-up excessively flows into; At last, between base concrete layer and grout blanket, band drain is installed, is passed through the underground water that the ground concrete layer permeates because of the effect of buoyancy, be directed into the collecting well place.
Waterproofing system of the present utility model has fundamentally solved building bottom and inner water seepage problem.This system is installed to sole plate below before building operations, directly need not excavate french drain to the underground water that oozes out in that plain concrete cushion layer is inner, directly in plain concrete cushion layer the underground water that oozes out, concentrate to be induced to the collecting well place.After the building completion, be installed to building foundation base plate top, the concentrated collecting well that is induced to of water that interior of building oozes out is handled, regulate buoyancy simultaneously, make the buoyancy that acts on sole plate keep certain, can control the influx of collecting well.For achieving the above object, the utility model is intended to set up makes the construction bottom ground water pressure keep stable water drainage structure, for guaranteeing underflow Inbound unanimity, at the inner drainage space that forms of sole plate top layer of concrete, the end of above-mentioned drainage space is mounted to collecting well, above-mentioned drainage space comprises vertical direction and rises, underground water is drained into the terminal connecting portion of relief pipe of collecting well, formation can be regulated the water drainage structure of buoyancy and the band drain on sole plate top, the water of discharging is induced to the collecting well place, thoroughly block percolating water, thereby reach perfect waterproof effect.
Discharge pipe line comprises plug connector, the plug connector inner hollow, four limits of plug connector all are provided with socket, socket peg graft respectively drainage channel, induce the water route, drainage channel with induce the crisscross setting in water route.Plug connector adopts the structure that connects drainage channel and induce the water route, forms drainage channel respectively and induces the crisscross setting in water route.
Water-filled pipe is connected to collecting well, utilizes connector to connect, and forms the underdrainage job practices of flowing water passage, when underground water flows in a large number, can rationally disperse and catchment, and forms several drainage channels, makes it to flow in the collecting well smoothly.
Drainage channel is rectangle or trapezoidal or annular or circle or triangle or semicircle with inducing the cross section in water route.
Drainage channel comprises the S bend pipe material, and the S bend pipe material arranges at interval and connects.
Induce the water route to comprise band drain, shrinkage pool is set on the band drain at interval, the bottom of shrinkage pool protrudes from band drain and forms boss.
The upper and lower surface of discharge pipe line wraps up geotextiles respectively.
For preventing phreatic excessive inflow, every certain position and in the end of collecting well swan-neck is installed.At interval swan-neck is installed, evenly peptizaiton avoids excessively discharging phreatic purpose in a kind of buoyancy of sole plate thereby reach.
Be to pass through 3 kinds of connected modes between discharge pipe line and the collecting well:
1. the pipe by straight line is communicated with between discharge pipe line and the collecting well.
2. the pipe by bending is communicated with between discharge pipe line and the collecting well.
Between discharge pipe line and the collecting well respectively the pipe by straight line and bending be communicated with.
When waterproofing system of the present utility model is installed the water flowing passage at underground soil layer, need not excavate french drain at smooth excavation face, together construct with plain concrete cushion layer, namely be installed to sole plate and get final product.In addition, the height of swan-neck is designed to be no more than a kind of buoyancy fixed level, thereby avoids threatening building safety.The whole band drain of laying in sole plate top is managed for passing through the water that first step waterproofing course permeates, concentrate to be induced to collecting well everywhere.
The utility model effect is to guarantee building and underground foundation stability, and remarkable waterproof effect effectively utilizes the underground space, improves the building service efficiency, reduces maintenance management expense from now on.
