The invention relates to the technical field of highway construction, in particular to a full-filling grouting process for a goaf, which comprises the following steps of: drilling to form a hole in a reducing manner, mounting a lower grouting pipe with a flange plate, filling gravels and clay, injecting cement paste, casting an orifice pipe, removing the upper grouting pipe after the grout is solidified and formed, and grouting the goaf through the lower grouting pipe. According to the method, the overlying strata are reliably supported and prevented from further caving through a firm filling body formed by drilling holes in the ground surface of an overlying strata area and grouting, the stability and the bearing capacity of an underground structure are enhanced, safety and stability of an upper structure are guaranteed, and the method is suitable for goaf treatment.
本发明涉及公路施工技术领域，尤其涉及一种采空区的全充填注浆工艺，包括：变径钻进成孔，安装下带法兰盘的注浆管，填入砾石、黏土后注入水泥浆，孔口管浇铸，待止浆液固结成型后移除上段注浆管，通过下段注浆管对采空区进行注浆。该方法通过在上覆岩层区地表打孔，通过注浆后形成的坚固填充体，对上覆岩层形成可靠支撑，阻止上覆岩层进一步冒落，并增强地下结构的稳定性和承载能力，保证上部结构物的安全稳定，适用于采空区的治理。
