Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of prevention and control devices, and more specifically, the utility model relates to a device for preventing and controlling the arching of a cement stabilized gravel road surface. Background Technique
[0002] Arch swelling is a Chinese term, which refers to the phenomenon that when the temperature of a cement concrete road surface rises, the slab body arches upward because the expansion joint cannot fully play its role. When a route obliquely crosses a river, in order not to change the original state of the river course, the bridge usually adopts an oblique intersection. The gravity type abutments of the built oblique bridges usually adopt mortar rubble masonry. After more than ten years of use, the front walls and side walls of the obtuse angle parts of the abutments of such oblique bridges usually arch and crack, a large amount of mortar seeps out and crystallizes on the outside of the front walls and side walls, and the corresponding bridge deck pavement layer of the abutment is fractured. In order to avoid the arching phenomenon of the cement stabilized gravel road surface during use, arching joints are generally opened on the cement stabilized gravel road surface and expansion joint boards are filled in the joints.
[0003] However, when filling the expansion joint board, generally, the operator directly fills the expansion joint board into the anti-arching joint by manual placement. Although this filling method is relatively convenient, it is extremely easy to cause the deformation of the expansion joint board after filling, resulting in a poor actual use effect. Summary of the Utility Model
[0004] In order to overcome the above-mentioned defects of the prior art, the embodiment of the utility model provides a device for preventing and controlling the arching of a cement stabilized gravel road surface. By arranging a feeding mechanism to cooperate with a placement plate to feed the expansion joint board, the phenomenon that the expansion joint board is deformed after feeding can be effectively avoided, so as to solve the problems raised in the above background technique.
[0005] To achieve the above object, the utility model provides the following technical solution: A device for preventing and controlling the arching of a cement stabilized gravel road surface, including a placement plate, a through hole is opened inside the placement plate, two guide plates are arranged at the bottom of the placement plate, the cross-sectional shapes of both of the two guide plates are set as inverted L shapes, a plurality of support rods are uniformly arranged on both sides of the placement plate, the cross-sectional shapes of the plurality of support rods are all set as inverted L shapes, a support plate is arranged at the bottom of the support rod, and a feeding mechanism is arranged on one side of the placement plate.
[0006] In a preferred embodiment, the feeding mechanism includes a fixing plate, a plurality of sliding grooves are opened on one side of the fixing plate, and sliders are arranged inside the plurality of sliding grooves.

[0011] In a preferred embodiment, a plurality of connecting rods are uniformly arranged on the top of the pressing plate. One ends of the plurality of connecting rods all penetrate through the movable plate and extend to the outside of the movable plate.
