Fixing device for tunnel inverted arch rubber waterstop and construction method

Abstract

The invention discloses a fixing device for a tunnel inverted arch rubber waterstop and a construction method, and relates to the technical field of fixing devices and methods for embedded rubber waterstops in the tunnel engineering construction process. The fixing device for the tunnel inverted arch rubber waterstop comprises a U-shaped clamping buckle and a buckle fixing support, wherein threaded holes are formed in two side plates, bolts are arranged inside the threaded holes in a matched mode, and the buckle fixing support is fixed to the portion, located outside a U-shaped groove, of a bottom plate. According to the fixing device for the tunnel inverted arch rubber waterstop, the rubber waterstop can be accurately positioned and fixed by adjusting the displacement of the bolts on the two side plates, the fixing device can accurately and stably fix the rubber waterstop, and guarantees that the rubber waterstop is in a straight and flat state all the time, and meanwhile, due to the fact that the fixing device can be circulated, the fixing device can be repeatedly used, saves material resources, and meanwhile, improves the efficiency of fixing work of the rubber waterstop greatly.

Description

technical field [0001] The invention relates to a fixing device and a method for a buried rubber waterstop during tunnel engineering construction, in particular to a fixing device and a construction method for a tunnel inverted rubber waterstop. Background technique [0002] The mid-buried rubber waterstop is a waterstop product mainly used in concrete deformation joints, expansion joints, etc. It has the ability to adapt to the expansion and deformation of concrete with the elasticity and structural form of rubber materials. [0003] At present, most of the construction joints between the inverted arch low side wall and the second lining middle wall of the tunnel project use the buried rubber waterstop. During the construction, the rubber waterstop needs to be temporarily fixed. The traditional method is to use additional steel bars to fix, Or use lead wire to perforate and fix the second lining template. The traditional method of rubber waterstop is inaccurate in positioni...

Problems solved by technology

[0003] At present, most of the construction joints between the inverted arch low side wall and the second lining middle wall of the tunnel project use the buried rubber waterstop. During the construction, the rubber waterstop needs to be temporarily fixed. The traditional method is to use additional steel bars to fix, Or use lead wire to perforate and fix the second lining template. The traditional method of rubber waterstop is inaccurate in positioning, unstable in fixation, easy to damage the waterstop when perforating, and will also cause twisting of the rubber waterstop, which cannot meet the requirements of the rubber waterstop. The construction requirements lead to the suspension of the construction, and the rubber waterstop must be fixed again, which is time-consuming and labor-intensive, and the construction quality requirements cannot be guaranteed
