Concrete structure repairing construction method
The invention discloses a concrete structure repairing construction method, and aims to solve the technical problems of low bonding strength and poor durability in concrete maintenance and reinforcement. The method comprises the following steps of (1) treating the surface of a to-be-repaired concrete structure to form an uneven shape, and measuring the surface roughness of the to-be-repaired concrete structure by adopting a sand filling method after the treatment is completed; (2) drilling a hole in the surface of the treated concrete structure, burying an anchoring rib and smearing an interface agent; (3) preparing fiber concrete, namely mixing fibers with coarse aggregate and fine aggregate, performing dry mixing for 30 seconds to 60 seconds, adding cement, a mineral admixture, water anda concrete admixture, and performing stirring for 90 seconds to 120 seconds to obtain the fiber concrete; and then pouring the fiber concrete on the surface of the concrete structure treated in the step (2). The high-performance fiber concrete is adopted to bond, repair and reinforce the existing concrete, the durability of the bonding surface is greatly improved, and the maintenance and repair cost can also be greatly reduced.
本发明公开了一种混凝土结构修复施工方法，旨在解决混凝土维修、加固中粘结强度低、耐久性差的技术问题。其包括以下步骤：（1）对待修复的混凝土结构的表面进行处理，使其形成凹凸不平状，处理完成后采用灌沙法测量其表面粗糙度；（2）在处理后的混凝土结构的表面钻孔、埋设锚固筋并涂抹界面剂；（3）制备纤维混凝土：将纤维和粗骨料、细骨料混合，干拌30s‑60s，然后再加水泥、矿物掺和料、水和混凝土外加剂搅拌90s‑120s，制得纤维混凝土；然后用所述纤维混凝土浇筑所述步骤（2）处理后的混凝土结构表面。本发明采用高性能纤维混凝土对既有混凝土进行粘结修补加固，粘结面耐久性能有大幅度提高，维护修理费用也能够大幅度降低。
