1、 Brief Introduction of Water Soluble Polymer Chemical Grouting Plugging Yancheng Zhiruixiang Waterproof and Leak Stopping Engineering Co., Ltd
High pressure grouting is to use mechanical high pressure power (high pressure grouting machine) to inject water soluble macromolecular chemical grouting materials into concrete cracks. When the grout encounters the water in concrete cracks, it will quickly disperse, emulsify and expand,
Consolidation, so that the consolidated elastomer fills all cracks in the concrete, and completely blocks the water flow outside the concrete structure, so as to achieve the purpose of water stop and leak 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. Yancheng Zhiruixiang Waterproof and Leak Stopping Engineering Co., Ltd
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, Yancheng Zhiruixiang Waterproof and Leak Stopping Engineering Co., Ltd
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. [Contact information: thirteen billion seven hundred and seventy million fifty-eight thousand five hundred and nineteen 】In concrete construction, expansion joint , Construction joint The treatment of water seepage and temperature stress cracks is a worldwide problem. In order to reduce the occurrence of various cracks in the concrete construction process, we have made continuous research and improvement in the selection of raw materials and construction technology in the current concrete construction process, but it can not be completely avoided. For example, in the Three Gorges of the Yangtze River, Xiaolangdi of the Yellow River, Wanjiazhai and other large and medium-sized water conservancy and hydropower projects, although various construction technologies have been adopted, There are strict quality assurance systems and control measures, but various cracks are found in concrete construction to varying degrees.
All kinds of cracks in the concrete not only produce negative effects on the structure Yancheng Zhiruixiang Waterproof and Leak Stopping Engineering Co., Ltd Good influence may also cause direct harm to the whole building. Especially for hydraulic structures, due to the generation of cracks in the concrete, such as cracks in the underwater part, water will leak along the cracks. For cracks above the water level, the capillary water in the cracks will cause further damage to the structure due to the repeated changes in temperature, which may cause damage to the structure.
Chemical grouting is a very effective construction method for concrete defect treatment. The chemical grouting method described in this paper can use different treatment processes for different crack types, which not only reduces the labor intensity in the construction process, but also can ensure the quality of defect treatment, shorten the construction period, reduce the cost of treatment, thus obtaining good economic and social benefits.
2、 Types of concrete defects and cracks and causes of water seepage Yancheng Zhiruixiang Waterproof and Leak Stopping Engineering Co., Ltd
Generally, the defects and cracks in concrete mainly include expansion joints, construction joints and temperature stress cracks.
2.1 Expansion joint: it is a transverse joint set in the structure according to the structural layout, geological conditions, construction layout, construction strength, etc. In order to meet the requirements of structural deformation, there should be no rigid filler between joint surfaces generally, and only water stop facilities should be set near the upstream dam surface. In the process of operation, the water seepage is mainly caused by the following two aspects: a. In the original construction process, the waterstop was damaged due to various reasons
； b, land be launched Circumferential seepage formed along the concrete defect part of the waterstop.
2.2 Construction joint: the other type of seepage joint is the horizontal construction joint of concrete Yancheng Zhiruixiang Waterproof and Leak Stopping Engineering Co., Ltd The main reason for water seepage is that the joint surface is not treated as required, and the joint surface is mortar It is less, and the height of concrete blanking is higher, which causes the partial separation of mortar and aggregate in the concrete, and insufficient vibration along some areas of the junction surface, resulting in partial seepage channels.
2.5 Temperature stress cracks: temperature stress cracks are the cracks that appear more in the concrete. During the construction process, due to the excessive temperature difference between the foundation and the inside and outside of the concrete, or due to other The stress release caused by the reason is the main reason for concrete temperature stress cracks. According to the different forms of thermal stress cracks, thermal stress cracks can be divided into surface cracks, deep cracks and through cracks.
2.4 General principles of crack treatment Yancheng Zhiruixiang Waterproof and Leak Stopping Engineering Co., Ltd
According to the type and location of cracks, the treatment methods are different,
The following principles shall be followed for the treatment of concrete cracks:
