What is the construction process of water plant pool expansion joint plugging?
1. Construction process: determine the leakage point → clean the leakage base surface → drill hole → clean → install grouting nozzle → high-pressure grouting foaming slurry → observe → repair leakage → remove grouting nozzle → slot hole repair → check → acceptance
2. Key points of construction:
(1) Mark the water seepage point accurately, and clean the water seepage part.
(2) The grouting pipe shall be embedded with quick plugging agent, and the spacing shall be determined according to the actual situation, generally about 1m.
(3) Use the electric high-pressure grouting pump to inject the water soluble polyurethane leak stopping agent into the concrete gap from the grouting pipe until it cannot be pressed (injection rate ≤ 0.011/min), then close the valve, and cut (remove) the grouting nozzle 24 hours later.
(4) In order to achieve long-term waterproof purpose, polyurethane waterproof layer can be painted on the construction surface.
(5) Clean equipment and tools with solvent after grouting.
(6) Keep the construction site ventilated, pay attention to fire prevention, and prohibit kindling.
What are the methods of leaking stoppage in the pool, and what is the construction process of leaking stoppage in the pool? I will tell you so much today. In fact, we can also solve the problem from the source, as long as we strictly control the quality of the materials, the chemical grouting materials used, with product certificates, instructions and technical reports, can be used only after the on-site sampling and retest are qualified, and no fake or inferior products will be used. In addition, the operating procedures and technical specifications shall be strictly followed, and no jerry building shall be done during construction, so that it is basically OK. Yancheng Zhiruixiang Waterproof and Leak Stopping Engineering Co., Ltd. was one of the first batch of enterprises with the first level of safety qualification for hanging work at heights of Jiangsu Administration of Work Safety, and the second level of professional qualification related to China's anti-corrosion construction power system.
1、 Brief Introduction of Water Soluble Polymer Chemical Grouting Plugging
High pressure grouting plugging is to use the mechanical high pressure power (high pressure grouting machine) to inject water soluble polymer chemical grouting materials 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, To achieve the purpose of water stop and leakage stoppage. High pressure grouting plugging technology is a new waterproof technology of high-pressure airless grouting with international advanced level, which is a new technology used in water-soluble grouting materials in developed countries.
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 and gel. 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 encounters water (water injection), it is accompanied by cross-linking reaction, releasing a large amount of carbon dioxide gas, generating secondary seepage pressure. The high pressure thrust and secondary seepage pressure 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.
