Problems solved by technology

[0002] In recent years, during the construction of various types of engineering foundation pits, fertilizer tanks, pipe culverts, tailings, cavities, lakes, coastline embankment reinforcement and anti-seepage backfilling, engineering excavation spoils have been transported out for disposal and backfilling materials have been transferred multiple times after construction , there is a contradiction between increasing dust points and maintaining pressure, and the utilization rate of underground space has not been used more efficiently. However, the excavation foundation of the current project construction, the pit space is narrow and deep, and the operation of traditional compactors is difficult; for special-shaped end faces, non-opening Backfilling of excavated holes and other working conditions usually adopts traditional plain / ash / cement soil / wet sand backfilling in layers. The situation of voids on both sides of the middle is difficult to overcome, resulting in poor impermeability of the backfill parts, and settlement of the empty soil after contact with water. The compacted part has a deformation space, and under the continuous action of external force, it shrinks and loses space, which has a great potential hazard to public safety; and it is backfilled with plain concrete, the project cost is high and the secondary maintenance excavation is difficult
In addition, a large amount of solid waste generated in the production process of the existing construction industry is usually made into backfill materials that need to be paved and rolled. This backfill material is limited by factors such as backfill conditions and space, and cannot be used without compaction. backfill compact

Abstract

The invention belongs to the field of comprehensive utilization of solid wastes, and particularly relates to a liquified consolidation material and a preparation method thereof. Solid wastes in industry, mining and construction industries as raw materials, a low-activity composite cementing material, a filling material, pulping liquid and an additive are prepared into a vibration liquefied consolidation material which is uniform in macrocosmic and microcosmic, large in flow state and capable of being pumped through a vibration stirring process. The liquified consolidation material has the advantages of being high in mobility, free of backfilling dead corners, self-hardening, free of vibration during forming, high in strength, anti-seepage, anti-seismic, stable in size, environmentally friendly and the like, is suitable for backfilling of fertilizer grooves, pipe culverts, cavities and abutment backs, reinforcing of building foundations, filling of road roadbeds, reinforcing and seepage prevention of river channels, lakes and coastline embankments and the like, and solves the problems that the space is narrow, tamping of special-shaped end faces is uneven, non-excavation cavity backfilling is not in place, and traditional stirring equipment for the flow-state solidified soil is not uniform in stirring.
