Description

Road curb crack repair structure Technical Field The utility model belongs to the technical field of highway engineering, and particularly relates to a highway curb crack repairing structure. Background Highway curb is an important infrastructure in highway engineering for separating lanes, guiding drainage and ensuring safety. Mainly comprises a vertical curb (15-30 cm in height, reinforced isolation), a flat curb (short and practical, convenient for vehicles to stop), an arc-shaped and barrier-free curb (suitable for curves or special requirements). The material is mainly made of concrete and stone, and has both cost and durability. The curb often causes the crack to its holistic steadiness because of external force collision, and part curb size is great, and whole change economic nature is poor, in order to further improve the life of curb, consequently need a highway curb crack repair structure, can add the symmetry to curb crack inner wall and plant the muscle, and connect planting the muscle through the connecting piece, later repair the crack through fibre web and filler to make the curb crack repaired, and then prolong its life. Disclosure of utility model The utility model aims to provide a highway curb crack repairing structure, wherein symmetrical embedded ribs are additionally arranged on the inner wall of a curb crack, the embedded ribs are connected through connecting pieces, and then the crack is repaired through fiber nets and fillers, so that the curb crack is repaired, the service life of the curb crack is prolonged, and the technical problems in the background art are solved. The technical scheme includes that the highway curb crack repairing structure comprises insertion holes and rectangular grooves, wherein the insertion holes are formed in the inner walls of the curb cracks, an implantation screw is inserted into the inner cavities of the insertion holes, a reinforcement adhesive layer is jointly filled between the implantation screw and the inner walls of the insertion holes, a fixing plate is integrally formed on the surface of the implantation screw, an orifice plate and a fiber net layer are sleeved on the surface of the implantation screw, nut blocks are connected to the surface of the implantation screw in a threaded mode, an epoxy resin adhesive layer is jointly filled between the orifice plate and the curb cracks, and a marble adhesive layer is jointly filled between the fiber net layer and the inner walls of the rectangular grooves. Preferably, the surface of the implantation screw is integrally formed with a branch. Preferably, the surface of the implantation screw is sleeved with a cushion block, and the cushion block is attached to the fiber net layer. Preferably, a first structural adhesive layer is filled between the fiber web layer and the top of the inner cavity of the rectangular groove. Preferably, the inner wall of the rectangular groove is provided with a rectangular opening, the bottom of the fiber net layer extends to the inner cavity of the rectangular opening, and a second structural adhesive layer is filled between the inner wall of the rectangular opening and the fiber net layer.
