[0002] Steel plate waterstop (waterstop steel plate) is a steel plate of 300mmx3m embedded in advance when pouring the lower layer of concrete, with 10-15cm of the upper part exposed outside. This part of the steel plate is poured in together when pouring concrete next time, which plays a role in preventing the infiltration of pressure water from outside. In the previous construction process, after the waterstop was flattened and installed, it was fixed with positioning clamps.

[0003] The patent document with announcement number CN210370712U discloses a tunnel longitudinal waterstop positioning device, which includes: a pair of steel clamps for clamping the ends of the two waterstops, the upper parts of the two steel clamps have an inverted U-shaped locking rod, the two ends of the locking rod respectively span the outer ends of the two steel clamps, and the two steel clamps are locked by a locking screw threadedly matched with the U-shaped locking rod. The utility model solves the problem that the longitudinal embedded rubber waterstop is not straight and not embedded in the concrete of the inverted arch and arch wall. The waterstop is fixed by the device, and the positioning accuracy and firmness of the rubber waterstop are improved. The installation quality and positioning accuracy of the longitudinal rubber waterstop are improved, and the lining seepage caused by the improper installation of the waterstop is reduced, the construction cost of the later treatment of seepage defects is saved, and the construction efficiency is improved.
