Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, and more specifically, to a water stop belt positioning tooling for tunnel construction. Background Technique

[0002] In tunnel construction, the water stop belt is used for waterproofing at the reserved construction joints, expansion joints of concrete linings and sectional joints of concrete protective layers. Because buildings often deform under the action of external factors, resulting in cracking or even damage. Expansion joints and construction joints are deformation joints reserved for this situation. Deformation joints are weak links in the waterproofing of waterproof concrete. Therefore, a water stop belt needs to be set at the construction joint. The rubber water stop belt has high elasticity and compression deformation properties. It stretches and squeezes as the deformation joint of the building changes to achieve the water stop effect, effectively preventing the leakage and seepage of building components, and playing a shock absorption and buffering role to ensure the service life of engineering buildings. When the water stop belt is installed in a tunnel, it needs to be positioned and supported.

[0003] After retrieval, the utility model patent with the publication number of CN220248113U discloses a tunnel water stop belt positioning frame. This device includes an upper clamping plate, a lower clamping plate, a baffle, a leg vertical rod and a leg base, etc. This device is applied to the positioning construction of the tunnel water stop belt. A stable foundation is formed between the leg vertical rod and the leg base and the base. The leg vertical rod and the lower clamping plate play a role in height positioning and lifting the water stop belt. The lower clamping plate is hinged to the upper clamping plate to lock the final position of the water stop belt. The baffle is connected to the upper clamping plate to play a role in counterweight and template construction limit, so as to meet the construction requirements. Therefore, this device can fix the position of the water stop belt when the water stop belt is not fixed at all, prevent it from dragging on the ground due to being too long, make the installation of the water stop belt convenient, shorten the construction operation time, reduce the secondary cleaning of the water stop belt, and this device can be reused, which not only meets the construction safety but also improves the material utilization rate. However, the above patent still has the following deficiencies: The leg base is only placed in the tunnel relying on its own weight, and its stability is poor. And the height adjustment of the upper clamping plate and the lower clamping plate through the cooperation of fixing bolts and adjustment holes has great limitations and is only convenient for adjusting to a few specific heights. For this reason, we propose a water stop belt positioning tooling for tunnel construction. Content of the Utility Model
