Description

Technical Field

[0001] The utility model relates to the technical field related to the positioning of tunnel steel plate waterstops, in particular to an adjustable positioning device for tunnel low side wall steel plate waterstops. Background Art

[0002] To ensure waterproofing of the construction joint between the tunnel invert and the arch wall, a longitudinal steel plate waterstop was installed in the longitudinal construction joint between the invert and the arch wall. Half of the steel plate waterstop was embedded in the invert, while the other half was exposed in the low side wall. As the arch wall concrete was poured, the steel plate waterstop was embedded in the invert and arch wall concrete, achieving maximum waterproofing.

[0003] The traditional way to fix the steel plate waterstop (also called waterstop steel plate) is to use a U-shaped steel bar clamp. The double-layer steel bar clamps the steel plate waterstop and sets an L-shaped connecting plate on one side, which is fixed to the end molds at both ends. After removing the end molds, the steel bar and the steel plate waterstop are straightened together. This method requires processing and shaping steel bars before fixing the steel plate waterstop and welding them to the end molds. The space is small and welding is difficult, and the buried position of the steel plate waterstop is difficult to control. It is common for the steel plate waterstop to be completely buried in the concrete or completely fall off. The bending and deformation of the steel plate waterstop causes the steel plate waterstop to be squeezed out of position by the concrete, which in turn causes water leakage in the construction joint. After the construction joint leaks, it can only be sealed with cement, which not only requires a lot of manpower and material resources to repair, but also destroys the original structural properties of the tunnel and cannot guarantee the construction quality of the tunnel.
