Soft sand foundation compaction grouting device and method
The invention relates to a soft sand foundation compaction grouting device and method, and relates to the technical field of compaction grouting, the soft sand foundation compaction grouting device comprises a grouting pipe used for being inserted into a drill hole and conducting grouting and a grouting device used for conveying cement paste into the grouting pipe, the grouting pipe is slidably sleeved with a sleeve seat, the sleeve seat is provided with a cutting unit and a rotating unit, and the cutting unit and the rotating unit are arranged on the grouting pipe. The rotating unit is used for driving the cutting unit to rotate and cutting the hole wall of a drill hole to form a containing groove, the sleeve base is provided with a blocking unit, the blocking unit can be inserted into the containing groove and block a gap between the grouting pipe and the drill hole, and an outlet of the grouting pipe is located below the blocking unit. Cement paste is effectively prevented from moving upwards through the drill hole and being sprayed out of the soil body, the range of the cement paste permeating into soil body holes is enlarged, and the strength of formed paste veins is improved.
本申请涉及一种软沙性地基压密注浆装置及方法，其涉及压密注浆技术领域，其包括用于插入钻孔并注浆的注浆管以及向所述注浆管内输送水泥浆的压浆装置，所述注浆管滑动套设有套筒座，所述套筒座上设有切割单元与转动单元，所述转动单元用于驱动所述切割单元转动，并切割钻孔的孔壁，形成放置槽，所述套筒座上设有封堵单元，所述封堵单元能够插入所述放置槽，并封堵所述注浆管与钻孔之间的空隙，所述注浆管的出口位于所述封堵单元的下方。本申请有效避免水泥浆通过钻孔向上运动从土体中喷出，增大水泥浆渗入土体孔隙的范围，提高形成的浆脉的强度。
