CZ-01 High pressure filling machine

CZ-01 high pressure grouting machine
CZ-01 high-pressure perfusion machine, the perfusion pressure can reach up to 70Mpa, and can enter micro cracks above 0.02mm. The model is small in size, easy to operate and carry (weight about 7kg). The product adopts modular design, which is convenient for assembly, disassembly and maintenance. Easy maintenance and construction, saving labor time.

Scope of application
Hairline cracks in subways, tunnels, reservoirs, underground structures, construction joints, expansion joints, cracks in post-casting zones, etc .; site improvement, bay engineering, floor slab and other reinforcement projects
Construction method characteristics
Using the thrust generated by the grouting machine, the plugging agent is sent to the middle of the crack of the structure, so that the plugging agent diffuses from the middle of the crack to the surroundings. After the plugging agent reacts quickly with water to harden, it will block the cracks, especially the concrete structure with a thickness of more than 20cm. Using this method to plug the leak is faster and more effective. The filling machine used in this method has a high filling pressure and a large flow rate, which can quickly stop the water, which is indeed an effective water blocking method. Especially for the leakage points of a large amount of water gushing, this construction method is even more magical.
