cutoff water and reinforcement method at wet crack and water leakage parts of concrete structure

摘要

The present invention relates to a cracking unit repair occurred in concrete, tunnels, concrete dams, or by leaks are sequentially injected into the foaming and non-foaming polyurethane resin to the crack portions of the various structures for generating the perfect order of the solid repair and reinforcement there are features that can be achieved.; Looking at the configuration in accordance with the process order, the first, but drilling a cracking section 10 centered at a predetermined interval to a distance of staggered (zigzag) with Earl Galicia packer through holes (11, 12) for insertion to form a, Chapter packer holes for 11 is a crack portion 10 that is the depth, in communication with two-thirds of the thickness of the structure to be perforated so as to have a predetermined inclination angle, and the end holes 12 for packer is one-third of the crack portions 10 depth after completing the drilling process (S1) for inclining perforated to communicate with the point, of the perforated section was fixed insert sheet packer (11a) to for through hole (11) packers,, one-part a foamed urethane resin 20, high pressure When slowly injected into the cracking unit 10 through the injector 23, whereby the foam within about 30 seconds times of about 30 to 35 by reaction with the effluent primary injection step of naemyeo push the effluent to the outside and completely index the leak site ( complete S2).; Then, the inserting end packer (12a) to end packer through hole (12), fixed, and then, gradually within the two-component non-cracking unit 10, the foamed elastic polyurethane resin 21 through the injector 23 of the high-pressure When injected, cracking unit 10-pack type one wherein the out foaming by sliding off the inside reacts with the foamed urethane resin 20 is cured by being completed, the secondary injection step (S3) with a permanent repair and reinforcement effects, and thereafter about After the 24 hours, the cracking unit 10 checks the portion to when confirming the occurrence of the leak, then no is re-injected, and at least when a leak occurs, the chapter and single packer (12a) Packer (11a) cutting the protrusion, and removing the chemical liquid flows out and complete the cement geupgyeol 22 degree and maintenance, the reinforcing process according to the present invention through the finishing process (S4) to finish the surface and the like.; As described above, the present invention is then a measure of the cracking portion depth, by the construction by using the through hole for field aperture for the packer and the end packers simple equation deriving a perforation depth of puncturing angle, the precise location where the drug solution is injected Packer is fixed to the insert, there is a precise and effects that can be a solid maintenance and reinforcement.; Further, by injecting the effluents react with one-part two-thirds the foamed urethane foam to crack portion by portion in a crack, crack portions push the effluent is continuously leak to the outside clearance and at the same time to achieve a complete order primarily via in without a separate drying step required, there is another effect that efficient degree possible.; Also, soon as the first order of the completion at the same time two-component non-foaming when injecting the elastic polyurethane, crack part-part work out foaming and pushed in to penetrate to the microcracks portion reacts with the foamed polyurethane resin completely the interior of the structure than there is another effect of making the seal.
