Description
Technical Field
The invention relates to the technical field of bridge maintenance equipment, in particular to a crack cleaning device for highway bridge maintenance.
Background
Crack cleaning devices are commonly used for highway bridge maintenance, and the surface of a highway is usually easy to crack. The susceptibility of the road surface to cracking typically includes several reasons: first, temperature changes create cracks. Because there is the difference in concrete internal temperature and surface temperature, cause great difference in temperature, especially for pier shaft bulky concrete more serious, cause inside and outside expend with heat and contract with cold degree differ, make the inside compressive stress that produces of concrete, and concrete surface produces certain tensile stress, when tensile stress surpassed the ultimate tensile strength of concrete, the concrete surface has just produced the crack. Secondly, the shrinkage of the concrete causes cracks. The concrete generates tensile stress due to spontaneous deformation of shrinkage without being affected by external force, so that the concrete is cracked and cracked. The shrinkage types causing concrete cracking are mainly plastic shrinkage and dry shrinkage. Thirdly, the construction process quality is poor and cracks are generated. In the concrete pouring and manufacturing process, if the construction process is operated illegally and the construction quality is low, cracks can be generated. For example: the rigidity of the template is insufficient, and the deformation is caused by the defect of installation; the slump of the concrete is unreasonable; the concrete pouring process is not in accordance with the regulations; over-tamping or under-vibrating the concrete; the concrete is not poured continuously, the interval time exceeds the initial setting time of the concrete, the interface of the new concrete and the old concrete is not properly treated, and the like. Fourthly, cracks are generated when the concrete is not cured properly. Since concrete curing is not specified according to the related art, the in-place curing part is also a main cause of crack generation. For example: early form removal, improper measures after form removal, frozen concrete or rapid dehydration and drying of the surface of the concrete, or no measures to cause large difference between the surface temperature of the concrete and the ambient temperature, and the like.
The existing highway pavement cracks are usually cleaned by impurity, dust and the like in the cracks when being repaired, and then the repair is carried out, so that the repair strength is ensured, but the cleaning cracks are usually cleaned manually, the efficiency is lower, and the cost is higher.
