AI Technical Summary
Existing prefabricated concrete drainage ditches are prone to leaks due to foundation settlement during installation and use. Furthermore, the joints are susceptible to aging and cracking due to long-term exposure to air, leading to leakage problems.
The module uses a protruding part and groove snap-fit structure, combined with sealing strips and limiting parts, to achieve fixation and sealing between modules and avoid secondary filling.
It effectively prevents water leakage, improves construction efficiency, extends service life, and reduces joint aging and cracking.
