Repairing method for unfilled corner and broken corner of shield segment
The invention discloses a repairing method for an unfilled corner and a broken corner of a shield segment. The repairing method comprises the following steps of S1, chiseling off uncompacted concreteand protruding aggregate particles at the broken corner; S2, thoroughly cleaning the broken corner on the shield segment, performing flushing with clear water, and waiting for dry state of the damagedsurface; S3, performing mortar mixing: preparing mortar, taking a proper quantity of materials according to the size of the broken corner, performing mixing according to general technical requirements, and uniformly stirring the mortar; S4, performing leveling and trimming after layer-by-layer filling is conducted, and after the mortar to be repaired is dried and hardened, grinding the surface tobe flat through a grinding machine; and S5, performing cleaning and wetting on the repaired part through a steel wire brush, and then performing plastering finishing on the repaired part through cement paste. The repairing method for an unfilled corner and a broken corner of a shield segment effectively overcomes the defects that through a conventional repairing method, repairing strength cannotmeet the requirement, the repaired part is easy to fall off, and chromatic aberration is serious, it is ensured that the overall performance of the repaired shield segment is more complete and attractive, the waterproof and anti-seepage performance of a tunnel is further enhanced, and the overall quality of the tunnel is ensured.
本发明公开了一种盾构管片缺角、崩角的修补方法，包括以下步骤：步骤S1：凿掉崩角处不密实的混凝土和突出的骨料颗粒；步骤S2：将管片上的崩角处清理干净，并用清水冲冼，等待破损表面干燥；步骤S3：拌制砂浆：配制砂浆，根据崩角大小取适量材料按一般技术要求进行拌制，砂浆搅拌均匀；步骤S4：逐层填补后进行抹平、修边，待修补砂浆干硬后，用打磨机磨平表面；步骤S5：用钢丝刷对修补处进行清洗湿润，再以水泥浆对修补处进行抹面修整。本发明设计的管片缺角崩角修补方法有效解决常规修补方法修补强度达不到要求、修补后易脱落以及色差严重等缺点，确保修补后的管片整体性能更加完整、美观，进一步增强隧道的防水，抗渗性能，确保隧道的整体质量。
