Cement pipe wall crack water leakage plugging maintenance Cement pipe wall crack water leakage plugging maintenance is an important work, in order to ensure the normal operation and safe use of the pipeline, it needs to be repaired in time. The following are some common repair methods for water leakage and plugging of cement pipe wall cracks: 1. Cleaning the pipe: first, the sundries and blockages in the pipe need to be cleaned, which can be cleaned with a high-pressure water gun or cleaning agent. 2. Cutting pipe section: for large cracks, the leaking pipe section can be cut down by cutting. 3. Crack repair: use special cement glue or repair materials to fill and repair the leaking parts

The leakage of the reuse pool of Wuhu Sewage Treatment Plant has been remedied by water flowing grouting. A means of plugging seepage is based on plugging. Waterproofing is more complex, difficult and demanding than other engineering technologies. For a long time, people have become more and more aware of underwater engineering waterproofing and technical complexity. They have learned lessons from past underwater projects and summarized the combination of plugging and prevention, rigid and flexible, and local conditions Comprehensive treatment requires plugging, grouting, painting and plastering. The wet solid coating with strong moisture absorption ability shall be selected for the ventilation receiving surface of underwater engineering. It can absorb the moisture of the base surface to achieve the purpose of closely bonding with the base surface. All kinds of materials used in construction must have factories

What should we pay attention to when plugging the elevator shaft? How to deal with the leakage of the elevator shaft? How to deal with elevator shaft leakage stoppage? High pressure grouting is used to stop leakage, and then the construction of flexible waterproof layer and concrete protective layer are used to prevent the elevator shaft from leaking. How to deal with the foundation pit when the elevator enters the water? How to stop the leakage of elevator shaft and how to deal with the surrounding waterproof base course? Use a wire brush, grinder or 5% hydrochloric acid solution to remove the laitance, alkali, dust, oil stain, surface coating and other sundries on the base course surface, so that the concrete surface becomes smooth and rough, and then flush with water to neutral. Before using CCCW, the concrete surface must be washed again with clean water to make the concrete surface completely wet

Technology of Jiangsu Lanlong Construction Waterproof and Leak Stopping Engineering Co., Ltd.: leak stopping is done after water is available, and waterproof is done before water is available, so in order, waterproof is before water leakage, leak stopping is after water leakage, and leak stopping is a remedial measure, belonging to the maintenance category. There is no rated standard for plugging, but there is a rated standard for waterproofing. The warranty for plugging can be agreed, but the waterproof warranty is five years. The methods of plugging can be varied, and feasible schemes can be formulated according to the actual situation, but all methods are inseparable: plugging up and draining down, plugging and draining together. For all kinds of leakage, follow the combination of rigid and flexible, and use Rouke

How to deal with the leakage of the expansion joint of the reservoir How to stop the leakage of the expansion joint of the reservoir in the waterworks of Jiangsu Lanlong Building Waterproof and Leak Stopping Engineering Co., Ltd? The expansion joint plugging company adopts high-pressure grouting for water plugging, and uses oil-based foaming polyurethane. The oil-based polyurethane quick plugging adhesive reacts with water. Because water participates in the reaction, the slurry will not be diluted and washed away by water. Under the pressure, the grout is poured into the concrete gap or hole, and at the same time penetrates around the gap, and continues to penetrate into the concrete gap to form a network structure, forming an elastomer with low density and water content, which has good adaptability to deformation and good water stop performance.
