Concrete roof panel crack repairing method and device
The invention relates to the technical field of building construction, and provides a concrete roof panel crack repairing method and device.The method comprises the steps that a first groove body and a second groove body communicating with a target crack are formed in a concrete roof panel; deionized water is injected into the first tank body, so that the deionized water in the first tank body seeps to the second tank body through the target crack; when the concentration of harmful ions is reduced within a preset value; the grouting agent is injected into the second groove body, so that the target crack is filled with the grouting agent in the second groove body, and the grouting agent overflows to the first groove body through the target crack; and repairing the first groove body and the second groove body. According to the method, on the premise that damage to the concrete roof panel is small, harmful ions in the concrete roof panel are removed, and cracks are repaired. The local minimally invasive repair method not only solves the problem of structural damage caused by the drilling process of the traditional chemical grouting method, but also remarkably prolongs the durability life of the concrete structure by diluting harmful substances and then chemically filling.
本申请涉及建筑施工技术领域，提供了混凝土屋面板裂缝修复方法和装置，方法包括：在混凝土屋面板上开设与目标裂缝连通的第一槽体和第二槽体；将去离子水注入第一槽体，使第一槽体中的去离子水通过目标裂缝渗流至第二槽体；当有害离子浓度降低到预设值以内时；将灌浆剂注入第二槽体，使第二槽体中的灌浆剂填充满目标裂缝，并通过目标裂缝溢出至第一槽体；修复第一槽体和第二槽体。本发明在对混凝土屋面板破坏较小的前提下，实现了对混凝土屋面板中有害离子的去除以及裂缝的修补。局部的微创修复方法不仅解决了传统化学灌浆法钻孔过程带来的结构损伤，而且通过先稀释有害物质再化学填补显著提升了混凝土结构耐久性寿命。
