Patent construction method! Economically and accurately repair tunnel lining concrete with compact construction!
The "Steel Plate Adhesive Method for Lining Repair" is a technique that allows for the economical and precise repair of aging tunnel lining concrete. By connecting steel plates of a specified length on-site using splice plates, anchoring them along the inner surface of the lining, injecting, and maintaining the lining with the rigidity of the steel, the required repair effect can be achieved simply by adjusting the installation pitch P1 and P2 of the steel plates. This compact construction method can be applied regardless of the site and allows for work to be carried out while the tunnel remains in use. 【Features】 ■ Maintains lining with the rigidity of steel ■ Achieves the required repair effect simply by adjusting the installation pitch of the steel plates ■ Compact construction that is not site-specific ■ Can be executed while the tunnel remains in use ■ Manual construction is possible from transportation to execution, eliminating the need for construction machinery *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 ■ Since it does not cover the entire lining, it allows for visual confirmation of repair conditions after construction and observation of lining deformation over time, making maintenance easy. ■ Both material and construction costs are economical compared to other conventional repair methods. ■ It is suitable for ground reinforcement with rock bolts and can be used in conjunction with backfilling, providing a higher repair and reinforcement effect. ■ It does not narrow the tunnel's internal space limits like H-shaped supports. *For more details, please refer to the PDF document or feel free to contact us.
