Pervious concrete crack repairing construction method
The pervious concrete crack repairing construction method comprises the following steps that S1, a guide seam and a transverse seam are cut along a crack; s2, reinforcing agents are poured into the transverse joints and gaps below the transverse joints, and then opposite-pulling rib plates are arranged in the transverse joints; s3, after the rib plates and the pervious concrete are fully bonded and solidified, the guide seams are subjected to seam expanding treatment; s4, the surface of the guide seam is coated with a reinforcing agent, and then a concrete mixture is poured; s5, repairing paint on the surface of the poured pervious concrete after curing to fuse the new pervious concrete and the old pervious concrete; through concrete reinforcement connection, special material crack pouring, new and old concrete interface and a series of repairing treatment, the impression effect, overall strength and durability of a repaired part are enhanced, the technical problem that the repairing effect is poor due to the characteristics of pervious concrete is solved, the performance of the repaired concrete is close to or even superior to that of old concrete, and the service life of the repaired concrete is prolonged. The method is especially suitable for repairing cracks which are penetrated or not penetrated but developing due to natural aging, external force impact and other factors.
本实施例的透水混凝土裂缝修复施工方法，包括以下步骤：S1，沿着裂缝切割导向缝和横缝；S2，向横缝以及横缝以下的缝隙中灌注加固剂后向横缝中设置对拉筋板；S3，待筋板与透水混凝土充分粘结固结之后将导向缝进行扩缝处理；S4，向导向缝表面涂刷加固剂后灌注混凝土混合料；S5，养护后在灌注的透水混凝土表面补漆使新旧透水混凝土融合；通过混凝土加筋连接、采用特殊材料灌缝以及新旧混凝土界面等一系列的修复处理，增强修复部位的观感效果、整体强度和耐久性，解决因透水混凝土特性而导致的修复效果不佳的技术难题，修补后的混凝土性能接近乃至优于旧混凝土，尤其适用于那些由于自然老化、外力冲击等因素导致贯穿或未贯穿但在发展的裂缝修补。
