The quality is excellent, construction is fast, 100% safe without any worries, and the qualification rate of projects reaches 99.9%. Currently, our company has branch companies in most cities all over the country. Construction teams are spread throughout the country. All units are welcome to call for consultation and cooperation.
1. Basement plugging project: Carry out plugging and repair for the leakage phenomena that appear in basements, underground passages, basement garages, etc. Common methods include blocking method, grouting method, plastering method, and sheet material pasting method.
2. Pressure-carrying plugging project: Company's patented technology for non-stop plugging under pressure with flanges, top-pressure adhesive bonding flange plugging. Online non-stop valve plugging technology under pressure, leakage at upper and lower connection points, leakage from valve stem packing box, etc., oil storage cabinet leakage without unloading oil.
3. Tunnel plugging project: Undertake various highway tunnels, subway tunnels, railway tunnels, mountain ridge tunnels, twin-arch tunnels, cold area tunnels, karst tunnels, urban subways, immersed tube tunnels, and other plugging projects.
4. Mine well plugging: Professionally engage in plugging various coal mine wells. Large-scale mining of coal resources can easily destroy the groundwater environment of the mining area, causing changes in hydrogeological structures, forming an underground precipitation funnel centered on the mine well, altering the replenishment, flow, discharge movement patterns, and storage conditions of shallow, medium, and deep underground water sources, making the groundwater above the coal seam, even surface water, gradually seep into the mine well. To ensure normal mining conditions, cable trench plugging, coal mines need to adopt measures such as dewatering and depressurization and external drainage of mine wastewater, reducing the roof water pressure and the impact of continuously surging groundwater from tunnels and recovery faces on production. This method will cause a drop in water levels within the region, reduce surface runoff, and cause water flow interruption, resulting in waste of water resources, while the large amount of generated mine wastewater will also pollute regional water resources.
5. Expansion joint plugging: Professionally undertake various bridge expansion joints, dam plugging, and building expansion joint places where seepage occurs in plugging projects.
6. Cable trench plugging: Professionally undertake various electric wire and cable trenches, substation cable trench plugging projects.
7. Underground tunnel plugging: Professionally undertake hydropower station underground tunnel plugging projects.
8. Coal conveying corridor plugging: Professionally undertake glass factory, power plant, steel plant coal conveying corridor plugging projects.
9. Pump room plugging: Professionally undertake hydropower station, sewage treatment plant, power plant pump room plugging projects.
Third, performance of plugging materials:
After mixing four types of high molecular chemical materials (A, B, C, D), they become liquid, having good hydrophilic properties. Water serves as both a diluent and a curing agent. It has strong permeability, capable of penetrating into the capillary cracks of concrete structures. Before solidification, it can penetrate everywhere like water. When the slurry encounters water, it disperses and combines, then gels and solidifies.
The above plugging materials have good hydrophilic properties; water serves as both a diluent and a consolidating agent. It has strong permeability, capable of penetrating into the 0.01mm capillary cracks of concrete structures. Before solidification, it behaves like water, able to penetrate anywhere. Its density is lower than that of water. When the slurry encounters water, it disperses and combines, then gels and solidifies. In damp or water surge situations during grouting, it adapts strongly to different water qualities and can gelify in seawater and water with pH values between 3-13. The solidified gel is elastic and can swell when encountering water, possessing both elastic water stopping and above-water dual functions. Suitable for waterproofing and seepage prevention treatment in construction joints and deformation cracks in water conservancy, power, tunnels, subways, air-raid shelters, mine wells, and other projects. Plugging materials can be used with any mixing ratio to formulate materials with different strengths, penetration depths, solidification times, and expansion multiples. After grouting, as long as the deformation does not exceed 2.5mm, there will be no leakage in the basement, water tower, or tunnel.
