Maintenance method of underground pipe gallery leakage
(1) Before construction, record the leakage position of the underground pipe gallery and its surroundings, clearly record the current situation, so as to prepare for the subsequent construction; Before commencement, determine the waterproof structure in the settlement joint, the size and width of the settlement joint and the burial depth of the waterstop, and accurately find the grouting hole location according to the burial depth and width. At the same time, all drainage channels around the deformation joints of the underground pipe gallery shall be removed, and the deformation joints shall be cleaned. During the removal, the original waterstop in the deformation joints shall not be damaged, and the sundries in the joints shall be placed in bags.
(2) Clean the deformation joints. If necessary, use a high-pressure water gun to flush the joints to completely remove the sundries and laitance. Then, punch holes on both sides of the deformation joints. Find the location of the holes according to the height of the waterstop and the size and width of the settlement joints.
(3) The quick setting waterproof plugging can be added from the joint first to reduce the pressure of external water on the underground pipe gallery. When the water pressure becomes smaller and there is no more water gushing out, the foamed polyurethane can be poured on the outside of the waterstop, so that the foamed polyurethane can completely fill the gap, and continue to pour on the outside of the deformation joint under the condition of constant pressure, Pouring material can transform the original underground
The gaps on both sides of the waterproof layer and deformation joint of the pipe gallery are fully filled.
(4) After pouring outside, water will hardly leak from inside. At this time, pur-3102 and 3100 foamed polyurethane imported from Germany * * * can be poured inside the deformation joint, and the waterstop in the settlement joint will be completely wrapped in the foamed polyurethane waterstop. The foamed polyurethane will foam when encountering water, so that the foamed polyurethane will not completely fill the gap, Moreover, the foaming agent will also slowly penetrate into the surrounding cracks to completely fill and compact the deformation joints and surface structure, thus achieving better waterproof effect.
(5) When the deformation joint is filled with water swellable waterstop, the waterstop can be tightly embedded into the belt joint. The waterstop is a rubber elastic product with high bonding performance with the structure, and can resist the shear deformation of the structure. The waterproof plugging material with strong filling ability on the outside of the waterstop can squeeze the waterstop into the deformation joint, A strong protective layer is formed on the surface structure of the crack. In order to avoid the deformation of the deformation joint of the surface structure in the later stage, the flexible sealing material can be used to completely fill the inside of the deformation joint.
(6) After the construction of the above waterproof layer is completed and after observation for a period of time, after ensuring that the waterproof layer can play a good waterproof effect, rubber waterstop can be pasted outside the deformation joint of the surface structure and outside the groove inlay, which is a good waterproof measure 1、 Brief Introduction of Water Soluble Polymer Chemical Grouting Plugging
High pressure grouting is to use the high pressure power of machinery ( High pressure filling machine ) ， Water soluble macromolecule chemical grouting material is injected into the concrete cracks. When the grout encounters the water in the concrete cracks, it will quickly disperse, emulsify, expand and consolidate. This consolidated elastomer fills all the cracks in the concrete, and completely blocks the water flow outside the concrete structure, so as to achieve the purpose of stopping water and plugging leakage. High pressure grouting plugging technology is a new waterproof technology of high-pressure airless grouting with international advanced level, and a new technology used in developed water-soluble grouting materials.
2、 High pressure grouting plugging principle:
Water soluble polymer chemical grouting material is a kind of polymer cutting flexible elastic material, which is composed of several molecular materials of polymer chemical agricultural production system, and is proportioned according to strict proportioning standards.
Commonly used multi polymer materials include propylene, crystal, gel, etc three Species. Polyhydroxy compounds are polyethers, which can have several functional groups and molecular weights. After the grout is poured into the concrete crack, it will meet with the leakage water to produce chemical reaction, release carbon dioxide, and form macromolecular organisms. So as to achieve the purpose of seepage prevention and plugging.
Water soluble polymer chemical grouting material is a kind of bottom viscosity, one component synthetic polymer flexible elastic material in the form of flexible elastomer. It has the characteristics of cross-linking reaction when encountering water, and foaming to form a multi-element network closed elastomer. When it is injected into the concrete crack structure under high pressure to extend until all the cracks (including those that are hard to detect by the naked eye) are filled, when it meets with water (water injection), it is accompanied by cross-linking reaction, releasing a large amount of carbon dioxide gas, generating secondary seepage pressure. High pressure thrust and secondary seepage pressure will press the elastomer into and fill all the cracks,
To achieve the purpose of leak stop . It can be seen that the water soluble polymer chemical grouting material is one of the plugging materials with good performance. The leakage cannot be treated with ordinary materials. After the high-pressure grouting plugging technology is used, the leakage is successfully plugged at one time.
