Limestone water-containing layer grouting reconstruction material suitable for superlong-distance pumping
The invention relates to a limestone water-containing layer grouting reconstruction material suitable for superlong-distance pumping, and the material is composed of, in parts by mass, 65-70 parts of burned coal gangue, 20-25 parts of sulphate aluminium cement clinker, 8-15 parts of steel slag micro powder, and 9-12 parts of an extra-additive active initiator. The active initiator comprises, in parts by mass, 13-19 parts of alum, 20-28 parts of talcum powder, 8-13 parts of guar gum, 5-8 parts of hydroxypropyl methyl cellulose, and 40-55 parts of gypsum powder. The material possesses the characteristics of being high in slurry stability, weak in environment temperature influence, suitable for long-distance pumping, good in grouting property, high in stone body density, high in impermeability, wide in raw material source, low in price, and the like.
