Grouting construction technology for goaf
The invention relates to a goaf grouting construction technology, and relates to the field of goaf governance, the goaf grouting construction technology comprises the following steps: S1, construction preparation, and site cleaning; s2, point fixing: applying a total station or a dynamic GPS (Global Position System) to carry out field survey lofting, and installing a drilling machine in place; s3, hole forming is conducted, specifically, grouting holes are formed in sequence in the construction process; s4, a grouting pipe is installed; s5, slurrying is conducted, cement fly ash slurry is selected as a pouring material, the pouring slurry is composed of water, cement, fly ash, an accelerator and coarse aggregate, the slurrying process is completed in a slurrying pool, the slurry stirring time needs to be strictly controlled during slurrying, and the fluidity and stability of the prepared slurry are both qualified; and S6, grouting is conducted, specifically, the stirred grout is poured into the goaf, in the grouting process, grouting holes in the relatively low elevation positions of a bottom plate of the goaf are constructed firstly, and then construction is conducted from low to high and from the edge to the center in the inclination direction. In the construction process, the grouting pipe is not prone to being blocked by grout, and therefore the construction progress and the construction efficiency can be guaranteed.
本申请涉及一种采空区注浆施工工艺，涉及采空区治理的领域，其包括以下步骤：S1，施工准备，清理场地；S2，定点，应用全站仪或动态GPS实地测量放样，将钻机安装就位；S3，成孔，注浆孔在施工过程中应分次序成孔；S4，安装注浆管；S5，制浆，灌注材料选用水泥粉煤灰浆液，灌注浆液由水、水泥、粉煤灰、速凝剂及粗骨料组成，制浆过程在制浆池内完成，制浆时需严格控制浆液搅拌时间，制出的浆液需流动性与稳定性均合格；S6，注浆，将搅拌完成的浆液灌注到采空区内，在灌注过程中首先对采空区底板标高相对较低位置的注浆孔进行施工，再沿倾斜方向由低向高、向边部向中心展开施工。本施工工艺中浆液不易堵塞注浆管，从而可保证施工进度及施工效率。
