The invention provides a pavement repairing structure and method based on pavement pits, and relates to the technical field of pavement pit repairing. According to the pavement pit repairing structure and method, a to-be-repaired pavement and concrete are included, first reinforcing ribs which are evenly distributed penetrate through and are fixedly connected to the inner walls of the left side and the right side of the to-be-repaired pavement, and second reinforcing ribs which are evenly distributed penetrate through and are fixedly connected to the middle position of the inner wall of the top of the to-be-repaired pavement; the concrete is prepared from the following raw materials in parts by weight: 10 to 15 parts of an additive, 50 to 70 parts of 42.5 Mpa Portland cement, 150 to 200 parts of water, 30 to 50 parts of fly ash, 20 to 40 parts of silicon powder, 30 to 50 parts of river sand, 5 to 15 parts of gravel with the particle size of 19 to 25 mm and 10 to 20 parts of basalt fiber. By adding the corrosion inhibitor into the concrete for repairing, the corrosion phenomenon of reinforcing ribs in the concrete can be effectively avoided, and by adding the early strength agent, the concrete can quickly reach the design strength, the construction and maintenance time is shortened, and the concrete is worthy of being vigorously popularized.
本发明提供一种基于路面坑洞的路面修补结构及修补方法，涉及路面坑洞修补技术领域。该路面坑洞的修补结构及修补方法，包括待补路面和混凝土，所述待补路面左右两侧内壁上均贯穿并固定连接有均匀分布的第一加强筋，所述待补路面顶部内壁中间位置贯穿并固定连接有均匀分布的第二加强筋，所述混凝土包括以下重量份原料：10～15份添加剂、50～70份42.5Mpa硅酸盐水泥、150～200份水、30～50份粉煤灰、20～40份硅粉、30～50份河砂、5～15份粒径为19mm～25mm的碎石、10～20份玄武岩纤维。通过在修补用混凝土内，添加阻锈剂，可以有效避免混凝土内加强筋发生锈蚀现象，添加早强剂，使得混凝土可以快速达到其设计强度，减少施工养护时长，值得大力推广。
