Description
The present invention relates to the leak-stopping engineering of wall infiltration, furtherly, be meant a kind of technology of pouring and filling of polyurethane fast leak-stopping.
Taiwan is a fabric of island-in-sea type area, and amount of rainfall is abundant, a large amount of rainwater are especially arranged in plum rain season, so house architectural structure often must bear the erosion of moisture and rainwater.
In general, ground building causes wall surface infiltration reason, one is handled imperfection for the windowsill slot, one to rainy day, then rainwater infiltrates via windowsill, cause and leak, it is that main house body building structure is unsound that a kind of situation of leaking is arranged again, wall surface will produce the crack, this building is through after a while, and rainwater also can be scurried into gradually along this crack, progressively corrodes wall its crack is strengthened, if in time do not handle, what for to the structure that can therefore destroy entire wall and monolithic architecture thing.
And be positioned at the building of subterranean layer, on the one hand must bear the pressure that the underground soil is pushed,, make pressure that wall surface must bear greater than ground building again because a large amount of phreatic hydraulic pressure, therefore the easier wall surface generation crack that makes causes drainage.In case the underground water of tool acidity begins to infiltrate wall, will progressively corrode the reinforcing bar of burying underground in the wall, this point can all be filemot phenomenon by the water that flows out and can learn.Thus, bar construction begins to wreck in the building, if do not repair at once, will have a strong impact on whole solitary building braced structures time one for a long time, produces major crisis.
Solve the conventional method of this seepy question, only after finding leakage point, spread, fill up outside wall surface often with the cementing agent brush, stopping leaks continues to ooze out wall again, building is then brushed the shop synchronously, is filled up in the exterior wall place on the ground, so sealing rainwater in passive mode infiltrates, can not solve the infiltration that has been present in the wall in fact, the time one is of a specified duration, and wall still has and storEd the worry that continues corrosion in interior water.
Just more be difficult to resolve certainly and be positioned at leaking of subterranean layer, because it can't be two-way anti-blocking from wall face, thus, only smear the practice of cementing agent or guiding current with single face (being wall inside), to handle leakage point, will cause the interior ponding of wall to increase by outside continuation of wall, but do not lead the situation that pipeline relieves on the contrary off, so, cause the disappearance that is difficult to remedy with easier destruction entire wall structure.
The inventor is actively studied improvement based on the experience of being engaged in this class engineering construction for many years, through repeatedly experiment and improvement, has founded a new leak-blocking technology.
The purpose of this invention is to provide a kind of quick leak-blocking technology by pouring and filling of polyurethane, it soon short stopping ooze, and really in any micro gap of filling in wall, reach by the effect of thoroughly filling up fast leak-stopping in the wall.
The technology of a kind of pouring and filling of polyurethane fast leak-stopping of the present invention, its processing step is as follows:
Step 1: check and set out the wall surface leakage point;
Step poly-two:, be drilled with the hole of a desired depth to this wall surface ecto-entad with auger according to the leakage point of setting;
Step 3: hollow type bottling body installing is entered this hole, through hole bottom, but the predetermined broken part of reservation hollow type bottling body is in the outer end of this wall hole;
Step 4:, cooperate high-pressure pump and conduit to combine with the hollow type bottling body that is installed in hole with hydrophilic polyurethane filling agent;
Step 5: the pressure that high-pressure pump produced is pressed into hydrophilic polyurethane filling agent in the hollow type bottling body, makes hydrophilic polyurethane filling agent in wall through the hollow type bottling body, is following the micro gap channelling everywhere that is caused because of infiltration;
Step 6: the water in hydrophilic polyurethane filling agent and the wall surface contacts, after a scheduled time, promptly produce expansion, hard and close, airtight foaming body;
Step 7: after treating that hydrophilic polyurethane filling agent foaming is finished, the predetermined broken part that can will expose wall hollow type bottling body fractures;
Step 8: modify the leveling wall surface with the leveling of flat-faced wheel machine, epoxy resin and scraper at last, so get final product the wall of a permanent seepage prevention, leak-stopping.
During leakage point on setting wall surface, for the pressure of considering the polyurethane filling agent must be that each leakage point setpoint distance be the best for about 15～30 centimeters under the wall situation about can bear.
The filling agent of polyurethane described in the technology is to adjust host and accelerator by one to mix together with 2: 1 ratio, adjusts host and be expansion type polyurethane composition for best, and accelerator is with hydrophilic catalyzer, and for example multi-hydroxy polyether be the best.
Advantage of the present invention, a kind of quick leak-blocking technology by pouring and filling of polyurethane of the present invention is to reach the boundary that known construction technology can't be accomplished with the technology of innovating fully, thoroughly the antiseepage leak-stopping.The leakproof technology of only oozing of the present invention, be that with known construction technology maximum different this technology can initiative finds out each naked eyes in wall and can't distinguish the micro gap of looking, and needn't dig cutter, destroy under the structure of wall, really fill up each road micro gap, carry out blocking infiltration, crack fully with positive method, guarantee that wall construction no longer continues the corrosion of being seeped water by thoroughly filling up in the wall, and it is rapid and simple to construct, and is a kind of new technology that breaks through known construction technology fully.
