News Abstract: the material has good hydrophilicity, can react with water, generate CO2 gas at the same time, and penetrate and diffuse along the incoming water channel against the water, consolidate with the surrounding concrete, sand, soil, etc., quickly harden to form an impermeable consolidation layer, which has been widely used to block water gushing under high pressure and prevent water flow and water infiltration in foundation.

Leakage stoppage of sewage tank Characteristics of materials to be used
(1) the material has good hydrophilicity, can react with water, generate CO2 gas at the same time, and permeate and diffuse along the incoming channel against the water, consolidate with the surrounding concrete, sand, soil, etc., rapidly harden to form an impermeable consolidation layer, which has been widely used to block water gushing under high pressure and prevent water flow and water seepage in foundation.
(2) the material has a large cohesive force with concrete and soil particles, and can be made into high-strength elastic consolidation body, so it can fully adapt to the deformation of foundation or other base, so that it is not easy to find the initial strength of reinforcement due to cracking and collapse.
(3) in the water bearing structure, the slurry will not be washed away. In the reaction process, due to the diffusion of gas, the effective consolidation zone increases rapidly, and the consolidation body larger than other types of chemical grout can be obtained.
(4) according to the different needs of the project, the viscosity of the chemical grouting liquid can be adjusted. For concrete engineering, such as the basement and other small cracks, the slurry can quickly penetrate into it, forming a strong bond and impermeability.
(5) the solidification speed of slurry can be adjusted according to the construction needs.
(6) the single grouting equipment is adopted in the construction, which is easy to clean, the process is simple and easy to operate, and the comprehensive cost is low.
(7) immersion of consolidated body in water is harmless, non-toxic and pollution-free.
Operation technology and key points of leakage stoppage construction of sewage pool
1. Construction technology: determine the water leakage point → clean up the leakage base surface → drill hole → clean → install the grouting nozzle → high pressure grouting foam slurry → observation → leakage repair → dismantle the grouting nozzle → repair the slot hole → check → acceptance
2. Key points of Construction:
(1) locate the water seepage point and clean the water seepage part.
(2) the grouting pipe shall be embedded with rapid plugging agent, and the spacing shall be determined according to the actual situation, generally about 1 m.
(3) use electric high-pressure grouting pump to inject water-soluble polyurethane plugging agent into the concrete void from the grouting pipe until it can not be pressed (injection rate ≤ 0.011/min), then close the valve and cut off (remove) the grouting nozzle after 24 hours.
(4) in order to achieve long-term waterproof purpose, polyurethane waterproof layer can be painted on the construction surface.
(5) clean the equipment and tools with solvent after grouting.
(6) keep ventilation at the construction site, pay attention to fire prevention, and prohibit fire. Website: micheledimaio.com
