    Analysis of the cause of leakage External factors
    the urban integrated pipe gallery belongs to the underground project, may be under the river, located along the river, etc. , the original waterproof layer by backfilling, subside, vibration and other factors, lost the "barrier" function.structive factors
    large volume, large area of rebar in the actual construction process, due to the limitations of construction conditions, resulting in water ash ratio control is not strict, the amount of water resistance is not equal, sand and stone quality can not meet the requirements, vibration is not in place or even local leakage, construction seam treatment is not proper and rubber water stopper pre-buried false or partial, broken, so that the compactness is reduced, can not reach the design anti-permeability requirements of the structure self-waterproofing.environmental factors
    the upper load distribution of the pipe gallery is uneven, and its frequent train traffic produces strong vibrations, resulting in cracking of the crucifixion structure, loosening of the subsiding seam rubber water stopper belt and cracking to produce leakage.technical solutions seeding and other large flow of leakage treatment
    1) manual along the leakage seam removal "V" type groove, specifications 80mm to 100mm deep, width 60mm to 80mm, with water to flush the surface ash clean.
    the buried slurry pipe PVC 8mm, interval 500mm to 800mm water pipe first drainage pressure, first with ZT-106 plug leakage King quickly closed and then with re-filling ZT-108 water-soluble polyurethane grout filling slurry to plug the leak.
    2) set specifications 25×40 wood mold, with osmosis crystallization paint to fill the gap, molded slot embedded in the water expansion stop bar, thickness of 40mm.
    3) with KS-901E type resistant polymer waterproof mortar to fill the backing, and finally with tied wire mesh patching about 25mm thick.structure cracks and other small flow of seepage treatment
    1) artificial along the cracks to pick "V"-type grooves, slotting specifications depending on the specific situation, with water to flush the surface floating ash clean.
    2) KS-101 cement base osmosis crystalline waterproof coating seal leakage.
    3) with KS-901E easy-resistant polymer waterproof mortar to fill the backing, and finally with tied wire mesh patching about 25mm thick.leakage treatment
    1) base surface after chisel hair, rinse with clean water.
    2) KS-101 cement base osmosis crystalline waterproof coating applied to the seepage site, so that it is immersed in a subtle permeable pore.
    3) with KS-901E easy-resistant polymer waterproof mortar to fill the backing, and finally with tied wire mesh patching about 25mm thick.point leakage treatment
    1) with an electric hammer, buried slurry pipe drainage pressure.
    2) first with ZT-106 leak king quickly closed, to be strong after the first down and then in the order of filling ZT-108 water-soluble polyurethane grout.
    3) After inspection of no leakage, cut off the slurry pipe, with KS-901E easy-resistant polymer waterproof mortar seal.
    4) for the smaller parts of leakage to take KS-101 cement-based osmosis crystalline waterproof coating directly blocked. strong vibration site treatment
    1) after the above treatment of the site, and then in the leakage area along the leakage seam interval of 200mm, at an angle of 45 degrees in turn drilling the slurry hole.
    2) install a slurry nozzle with a stop-flow door, first fill the water moist seepage walkway, and seal the slurry mouth around.
    3) according to the order of the first bottom hole gradually to the high hole, the use of "ZT-107 modified epoxy grout" secondary filling fine gap, that is, intercepting and cutting off the leakage source, while making the structure of the crucified further reinforcement.
    4) the outer layer is then painted with two JS cement-based waterproof coating 1.2mm thick. Introduction to the selection of leak-blocking materials Shield solid 101 cement base osmosis crystalline waterproof coating product features
    1) is a non-toxic, harmless, can be directly used in drinking water on the concrete structure waterproof coating.
    2) can be constructed on the surface and back of the concrete structure.
    3) can be directly constructed on a variety of material substations that are wet (no water) or dry.
    4) is highly active and can naturally heal fine cracks below 0.4mm.
    5) to protect the rebar from corrosion.
    6) protects the strength of the concrete structure and prevents the damage of the freeze-thaw cycle to the concrete.
    7) construction is simple, easy to operate, no construction seams, no need to set up protective layer after construction. Use range
