Method for repairing load transmission capacity of old cement concrete pavement joint
The invention discloses a method for repairing a load transmission capacity of an old cement concrete pavement joint. The old cement concrete pavement comprises a pavement slab, a base layer located below the pavement slab and a foundation located below the base layer. The joint is located on the pavement slab. The method comprises the following steps that 1, holes are obliquely drilled in the two sides of the joint respectively, and the lower end of each hole is positioned in the foundation; step 2, a steel pipe is added into each hole; and step 3, a cement paste is injected into each steel pipe. According to the method for repairing a load transmission capacity of the old cement concrete pavement joint, the problems that when a dowel bar or a pull rod is arranged on an existing joint, a pavement excavation area is large, materials cannot be recycled, a certain amount of cement concrete materials need to be consumed for repairing, and the cost is increased are solved.
本发明公开了一种旧水泥混凝土路面接缝荷载传递能力修复方法，旧水泥混凝土路面包括路面板、位于路面板下方的基层以及位于基层下方的地基，接缝位于路面板上，具体按照以下步骤实施：步骤1，在接缝的两侧分别斜向钻孔，每个孔的下端位于地基中；步骤2，向每个孔中分别加入钢管；步骤3，向每个钢管中分别注入水泥浆。该旧水泥混凝土路面接缝荷载传递能力修复方法，解决了现有接缝设置传力杆或拉杆时，存在路面开挖面积较大，材料不能回收利用以及需要耗费一定量的水泥混凝土材料进行修复，增加成本的问题。
