Description

Technical Field

[0001] The invention belongs to the technical field of culvert reinforcement, and in particular relates to a culvert reinforcement device which is easy to install quickly. Background Art

[0002] In daily life, we often see various types of culverts. Culverts mainly refer to drainage channels or vehicle passages set under the roadbed in highway construction, which are generally built with bricks, stones or reinforced concrete. At present, traditional culverts mainly include two supporting walls and an arched plate erected between the tops of the supporting walls.

[0003] Because vehicles travel above culverts for a long time, some vehicles are relatively heavy, and the outdoor environment is harsh, the top of the culvert is prone to cracks or collapse, posing a safety hazard. Therefore, reinforcement devices are usually installed inside the culvert. Traditional reinforcement mechanisms have complex structures and are very cumbersome, time-consuming, and labor-intensive to install. They also consume a lot of resources and are extremely expensive.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows:

[0016] 1. By quickly erecting support columns on the inner walls of both sides of the culvert, a vault plate is built between two symmetrical support columns on the same side. The vault plate is installed on the positioning side plate of the bending rod and driven by a motor, so that the bending rod drives the vault plate to move along the vault wall of the culvert, thereby achieving the technical effect of rapid installation of the device.

[0017] 2. The bending rod is made of spring steel. The rolling roller is pressed tightly on the bending rod. The rotation of the rolling roller drives the bending rod to move upward. At the same time, the bending rod is deformed under the extrusion of the rolling roller, so that the bending rod is bent into an arc. When the top protrusion on the bending rod touches the vault wall of the culvert, the bending rod is bent into an arc in accordance with the vault wall under the extrusion of the vault wall. During the process, the vault plate moves with the bending rod, and the supporting groove at the top of the vault plate is bent with the top protrusion. At the same time, the back side of the vault plate is blocked by a baffle and the culvert wall. Under the mutual extrusion of the arc-shaped supporting grooves, the elastic part is deformed and bent. When the bending rods on both sides of the culvert move to the top, the upper end faces of the two top protrusions overlap, and at the same time, the originally flat vault plate is bent into an arc-shaped vault plate, thereby supporting the vault of the culvert.

[0018] 3. The support groove of the arch plate is an independent rigid support structure. The side walls of multiple support grooves are spliced ​​together to form an arc shape. The elastic part of the arch plate arranges the support grooves linearly. The elastic part of the arch plate has good elastic deformation ability, and then, driven by the bending rod, an arch support is formed on the top of the culvert, which has the technical effect of reinforcing the culvert.

[0019] 4. The movement of the bending rod will drive the support rod to move. During the movement of the support rod, the connecting column at the bottom will squeeze and pass over the wedge on the locking rod. As the top protrusions of the bending rods on both sides of the culvert fit together, the connecting column of the support rod passes over the wedges in the array on the locking rod and moves upward one by one, and finally stops at the top of a wedge plane, so that the support rod supports the top protrusion of the bending rod, forming a triangular stable structure, thereby improving the reinforcement effect of the culvert.
