[0006] Further, the flat plate is a metal plate.

[0007] Further, the left connecting straight rod and the right connecting straight rod are made of steel pipes.

[0008] Further, the width of the arc-shaped clamping ring is 3-8 cm, and the width of the flat plate is consistent with the width of the arc-shaped clamping ring.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model discloses a simple structure, low manufacturing cost, convenient to use, high reusability, solve the problem of manual operation difficulty, realize the waterproof board and blind pipe construction quality and construction progress, guarantee the tunnel overall construction quality and durability, guarantee the construction safety of worker.

[0011] The device can better guarantee the lining concrete quality after on-site use, improve the work efficiency of workers, reduce the subsequent cost caused by insufficient lining thickness, and obviously improve the on-site actual construction and project department management.
