化学灌浆技术是指处理钢筋混凝土裂缝和修补混凝土缺陷的技术。化学灌浆是将几种化学材料配制的浆液,用压送设备灌入混凝土裂缝中去,使混凝土粘结加固和达到防渗堵漏的目的。它是化学灌浆技术的重要手段。化学灌浆技术从20世纪70年代末在我国开始试用,到目前已得到了广泛的应用。主要适用于大型厂矿的地下室、设备地坑、地铁及河流污水治理的地下建筑(如变电所、泵站。隧道及越江隧道等)裂缝的漏水治理和钢筋混凝土结构物的梁板柱、墙、地板等裂缝的加固补强。
Chemical grouting technology refers to the treatment of reinforced concrete cracks and repair defects in concrete technology. Chemical grouting is the preparation of several chemical materials slurry, with pressure delivery equipment poured into the cracks in concrete to make concrete bonding reinforcement and achieve the purpose of anti-seepage plugging. It is an important means of chemical grouting technology. Chemical grouting technology from the late 1970s in China began trial, so far has been widely used. Mainly applicable to large factory mines in the basement, equipment pit, subway and river sewage treatment of underground buildings (such as substations, pumping stations, tunnels and tunnels, etc.) cracks in the leakage control and reinforced concrete structures beam column, wall, floor Reinforcing cracks and other reinforcement.
