Road and bridge crack repairing and fixing structure

Abstract

The invention discloses a road and bridge crack repairing and fixing structure, and belongs to the technical field of road and bridge repairing. The road and bridge crack repairing and fixing structure comprises a repairing and fixing bolt, a plurality of containing grooves are annularly formed in the upper end and the lower end of the outer wall of the circumference of a repairing cylinder at equal intervals, a plurality of inverted buckling rods are annularly arranged on the outer side of the circumference of an adjusting block at equal intervals, a plurality of limiting rods are annularly and rotationally connected to the outer wall of the circumference of the adjusting block at equal intervals through pin shafts, and two penetrating pouring holes are symmetrically formed in the upper surface of the repairing and fixing bolt. Through close fit between the structures, the invention solves the problems that: in the prior art, constructors need to excavate fractured parts along the two sides of a crack, the workload and difficulty of the constructors are increased, the fractured parts are excavated greatly, the overall bearing capacity of a road bridge is greatly reduced, and direct fracture can be caused in severe cases.The bridge or road is firmer, the repair efficiency is improved, and the condition of secondary cracking is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of road and bridge repairs, and more specifically, relates to a repairing and fixing structure for cracks in roads and bridges. Background technique [0002] Roads and bridges are generally composed of road surfaces, roadbeds, bridges, tunnel engineering, and traffic engineering. Among them, the road surface is the most vulnerable to cracks due to various reasons, and cracks not only reduce the service life of roads and bridges, It will also affect the subgrade due to the infiltration of rainwater. The existing pavement repair technology is to complete the repair of cracks by simply filling concrete. This method has a short duration of action and cannot avoid the expansion of cracks. The asphalt concrete peels off at the cracks, thereby forming cracks again, so a road bridge crack repairing and fixing structure is proposed. The document of prior art publication number CN210134365U provides a kind of road br...

Problems solved by technology

[0002] Roads and bridges are generally composed of road surfaces, roadbeds, bridges, tunnel engineering, and traffic engineering. Among them, the road surface is the most vulnerable to cracks due to various reasons, and cracks not only reduce the service life of roads and bridges, It will also affect the subgrade due to the infiltration of rainwater. The existing pavement repair technology is to complete the repair of cracks by simply filling concrete. This method has a short duration of action and cannot avoid the expansion of cracks. The asphalt concrete peels off at the cracks, thereby forming cracks twice, so a road bridge crack repair fixation structure is proposed

The document of prior art publication number CN210134365U provides a kind of road bridge crack repair fixing structure, and this device can dig out the crack by setting up the repair groove in the road body, so as not to continue to expand the crack. When in use, the construction personnel dig along the crack both sides, Digging out the irregular part of the pavement is convenient for repairing the pavement, avoiding the incoherence of the repaired pavement caused by the irregular part of the pavement, which leads to the occurrence of secondary fractures. By setting tension piles and The positioning pile can connect the road on both sides of the original crack, which is convenient for dispersing the load of the road. By setting the top plate and rainproof plate above the repair groove, it can block the pressure of the wheels, so as to prevent the vehicle from crushing the newly repaired road surface when passing by. Although the device has many beneficial effects, the following problems still exist: when the device is in use, construction personnel are required to excavate the fractured part along both sides of the crack, which not only increases the workload and difficulty of the construction personnel, but also the excavation of the fractured part is relatively difficult. If it is large, it will lead to a great reduction in the overall load-bearing capacity of the road and bridge, and it will lead to direct fracture if it is serious. Propose a fixed structure for repairing cracks in road bridges
