Method for repairing frozen and thawed concrete ground
The invention belongs to the technical field of concrete ground repairing, and provides a method for repairing a frozen and thawed concrete ground, which comprises the following steps: firstly, carrying out base layer treatment on the concrete ground; secondly, spraying a diluted concrete curing agent, and standing for 0.5-1.5 hours; then, an iron grinding head grinding sheet and a resin grinding sheet of different specifications on a special concrete board grinding machine are replaced to grind the concrete floor for multiple times, and a diluted concrete curing agent is sprayed when one-time grinding is not completed; according to the repairing method provided by the invention, the penetration depth of the concrete curing agent into the concrete pavement is 3-5cm, and meanwhile, the strength grade of the original concrete pavement can be improved by 1.5-2 times.
本发明属于混凝土地面修复技术领域，提供了一种混凝土地面冻融后修复方法，包括以下步骤：首先，对混凝土地面进行基层处理；其次，喷洒稀释混凝土固化剂静置0.5h‑1.5h；然后，通过更换专用混凝土板面打磨机上不同规格的铁磨头研磨片和树脂研磨片对混凝土地面进行多次的打磨，没完成一次打磨时均喷洒稀释混凝土固化剂；通过本发明提供的修复方法，混凝土固化剂渗透到混凝土路面深度在3cm—5cm，同时可以提高1.5—2倍原混凝土路面的强度等级。
