Rapid repairing method for road concrete slab staggering
The invention discloses a rapid repairing method for a road concrete slab staggering. The method comprises the following steps of(1) calculating the use amount of a repairing material, investigating the site, determining the specific construction site and range of slab staggering, measuring the height and length of each slab staggering position, calculating the repairing width according to the requirement that the processed slope is 1%, and then calculating the volume and weight of the repairing material,(2) preparing a repairing material: uniformly mixing the coarse aggregate, the fine aggregate, cement, water, a rubber-based reinforcing agent, a water reducing agent, fibers and an accelerator in parts by mass to obtain the repairing material,and (3) conducting repairing construction, specifically, using a steel wire brush for removing soil, dirt and loose parts in the filling range, using compressed air for blowing away dust, spraying a layer of water, after open water does not exist, smearing the slab staggering position with repairing slurry, evenly spraying a thin layer of dry sand and cement powder on the surface for curing and curing for 4-8 h, and obtaining the repaired pavement. The repairing method is short in maintenance time, and the obtained repaired pavement is high in strength.
本发明公开一种公路混凝土错台的快速修补方法，包括如下步骤：(1)修补料用量的计算，对现场进行调查，确定错台具体施工地点和范围，测量每处的错台高度、长度，并按处理后的坡降为1%的要求，计算修补宽度，然后计算出修补料的体积、重量；(2)修补材料的制备，按照质量份数，将粗集料、细集料、水泥、水、橡胶基补强剂、减水剂、纤维和速凝剂混合均匀，得到修补材料；(3)修补施工，用钢丝刷清除填补范围内的泥土、污物和疏松部分，用压缩空气吹掉粉尘，喷上一层水，待无明水后将修补浆料涂抹于错台处，在表面均匀洒上薄薄一层干沙和水泥粉养护固化4‑8h，得到修补路面。本发明的修补方法，养护时间短，得到的修补路面强度高。
