Repairing method for concrete anti-collision pier
The invention discloses a concrete anti-collision pier repairing method, and particularly relates to the field of concrete anti-collision pier repairing, the concrete anti-collision pier repairing method comprises an anti-collision pier, a protection plate, sealing slurry and polymer mortar, the polymer mortar is adopted to bond the protection plate and the anti-collision pier, enough bonding strength is formed, and the anti-collision pier can be repaired. The protection plate is made of ultra-high-performance concrete materials, sealing slurry is used for sealing gaps between the edge of the side face and the edge of the bottom face of the anti-collision pier and the protection plate, a cavity is formed, it is guaranteed that slurry is not leaked, then the cavity is filled with grouting materials, and the protection plate is firmly fixed to the outer side of the anti-collision pier through the bridging effect of the hardened grouting materials. The protective plate is simple in structure, high in compressive strength and bending strength, light in weight and convenient to carry, the thickness of the protective plate can be controlled within 10-20 mm, and the protective plate further has ultrahigh chloride ion permeation resistance and freeze-thaw resistance, so that the maintenance period of the protected crash bearer is greatly prolonged, the frequency is reduced, the traffic control time required by maintenance is greatly shortened, and the economic benefit and the social benefit are remarkable.
本发明公开了一种混凝土防撞墩修复方法，具体涉及混凝土防撞墩修复领域，包括防撞墩、防护板、封浆料以及聚合物砂浆，采用聚合物砂浆将防护板与防撞墩粘结起来，形成足够的粘结强度，并用封浆料将防护板与防撞墩侧面及底面边缘缝隙密封，形成空腔，保证不漏浆，然后采用灌浆料将空腔灌满，通过硬化的灌浆料的桥接作用将防护板牢牢固定于防撞墩外侧，由于防护板采用超高性能混凝土材料制作，抗压强度和弯曲强度非常高，防护板的厚度可控制在10‑20mm内，重量轻搬运方便，防护板还具有超高的抗氯离子渗透和抗冻融性能，使得被防护的防撞墩维护周期大大延长，频率减少，维护所需的交通管制时间大大缩短，经济效益和社会效益显著。
