Well plugging project, coal gallery plugging project, highway tunnel plugging project, subway tunnel plugging project, underground tunnel plugging project, pump house plugging project and other plugging projects. The registered capital of the company is 11.086 million yuan, and the working capital is more than 80 million yuan; It has a technical construction team of * * *, including 36 people with * * * professional titles and 126 people with intermediate professional titles. With Grade I anti-corrosion qualification, Grade I safety qualification and Grade II building qualification, the company has five branches and eighteen offices. The company has strong technical force and focuses on the training of waterproof technicians. At present, it has * * * leak stoppage engineering technology * * *, construction management personnel, advanced construction technology and technology and * * * construction team, For more than 40 years, * * * has been committed to the research and development of construction technology and materials for building waterproof and leak stopping. With the progress of science and technology, in recent years, the company has introduced foreign advanced waterproof and leak stoppage technology with pressure, impermeability and vibration resistance, adopted * * high-tech nano molecular waterproof materials, * * * prepared a new process of scientific pressure reducing grouting, * * * treated various underground engineering leakage, especially for massive concrete crack leakage, water tunnel engineering, settlement expansion joint leakage and leak stoppage With years of experience in maintenance and handling, the company is fully capable of difficult waterproof and plugging. The company adheres to the corporate style of "unity and hard work, forge ahead, rigorous and realistic, and hard work", and constantly blazes new trails. Relying on strong strength, scientific management and quality service, the company firmly adheres to the corporate tenet of "honesty and realism, serving the society, and users first". Act according to the modern enterprise management mode. According to the requirements of the Provincial Department of Construction, the Municipal Construction Commission, Party A's unit and the environmental protection department, the company has a hard target of civilized construction, quality * * *, lifelong responsibility and zero accidents. The construction personnel shall hold the "special industry technical operation qualification" issued by the Ministry of Labor, and all of them shall take part in life insurance, which will never worry about the construction unit. We are willing to work with our domestic colleagues to make our due contribution to the innovation and application of China's waterproof plugging technology. We sincerely welcome all enterprises and individuals to call us for consultation and negotiation. Give us a trust, and we will give you a satisfactory answer. Business consulting, The plugging effect is closely related to the materials. The materials provide the basic conditions and play a guarantee role for the plugging technology. The superior performance and high-grade materials should be reflected in the use technology. No matter what materials, they must match and adapt to the plugging technology operation. Therefore, in this project water The materials selected for plugging are: specially prepared and produced fast setting and expanding plugging * * * materials for plugging and repairing; Selective drain water Large leakage water The point is extended from the center to both sides, and the V-groove is chiseled with an impact hammer or manually. The width of the upper opening is 6-10 cm, and that of * * * is 6-10 cm. The bottom of V is a crack. After the V-groove is formed, use a hose (clamp strip) with a diameter of φ 0.5-1 to plaster, evacuate and embed grouting holes. The spacing between grouting holes is 80-150 cm, and it shall be ensured that the grouting holes are overlapped in radius.
2、 Embedding grouting nozzle:
The grouting nozzle is made of 4-6 branch PV pipes or cast iron pipes, buried in the trough, cleaned, and double quick water Mud or high grade water The mud handle grouting nozzle shall be firmly fixed in the trench, and the buried depth shall not be less than 2-4cm.
3、 Sealing leakage water position
After the grouting nozzle is buried, remove the leakage of grouting nozzle water In addition, any other leakage water Phenomenon or possible leakage water Sealing measures shall be taken for all parts (within a certain range) to avoid slurry leakage and bleeding.
4、 Trial injection
In leakage water When the grouting nozzle is buried and has a certain strength after sealing. Color for trial injection water Instead of grout, the grouting amount and time can be calculated to provide reference for determining grout mix ratio and grouting pressure. At the same time, observe the plugging and hole connectivity to ensure normal grouting.
5、 Installation and inspection
Install and check grouting machines and tools to ensure safe use in grouting construction.
6、 Grouting
Select one hole for grouting (select the lower part and leakage water The grouting nozzle shall be measured to * * *. After the grout is found in the multiple holes, the holes shall be closed immediately, and the grouting shall continue. The grouting pressure shall be greater than the pressure, so that the grout can seep along the water The channel shall be pushed forward until the grouting is stopped, the grouting nozzle shall be closed immediately and then the grouting shall be stopped. After grouting, the grouting hole and inspection hole shall be sealed tightly. After the grout solidifies, remove the grouting nozzle, observe the grouting plugging effect, and repeat grouting if necessary
