High-pressure jet grouting device for building construction
The invention relates to the technical field of building construction, and provides a high-pressure jet grouting device for building construction, which comprises a drill rod, a drill bit and a jet grouting device, the jet grouting device comprises a first mixing bin, a second mixing bin, a drill rod sleeve and the like, and the lower end of the drill rod is fixedly connected with the drill bit and a drill rod bottom supporting plate; the first mixing bin is formed by sealing two ends of a first outer sleeve and two ends of a first inner sleeve through a first upper sealing plate and a first lower sealing plate, the first outer sleeve is provided with a slurry spraying hole, the first upper sealing plate is provided with a cement slurry pipe connector and an additive pipe connector, the second mixing bin is formed by sealing two ends of a second outer sleeve and two ends of a second inner sleeve through a second upper sealing plate and a second lower sealing plate, and the second outer sleeve is provided with a second spraying hole. The first mixing bin, the second mixing bin and the drill rod sleeve sequentially penetrate through the drill rod and are fixedly connected in series, the water spraying pipe and the air spraying pipe penetrate through the drill rod sleeve, and the lower ends of the water spraying pipe and the air spraying pipe are connected with the water slurry pipe connector, the air spraying pipe connector, the water spraying pipe connector and the air spraying pipe connector respectively. During use, the upper end of the drill rod is fixedly connected with a drilling machine, and the mixing proportion of sprayed cement paste and additives can be adjusted during work, so that better hole forming quality is achieved.
本发明涉及建筑施工技术领域，提出一种建筑施工高压旋喷装置，其包括钻杆、钻头和旋喷装置，所述旋喷装置包括有第一混合仓、第二混合仓、钻杆套管等，钻杆的下端固定连接钻头和钻杆底托板，第一混合仓由第一上、下封板将第一外、内套管的两端封盖构成，第一外套管开有浆喷孔，第一上封板安装有水泥浆管接头和外加剂管接头，第二混合仓由第二上、下封板将第二外、内套管的两端封盖构成，第二外套管开有第二喷孔，第二上封板安装有水喷管接头和气喷管接头，第一混合仓、第二混合仓和钻杆套管依次穿入钻杆并固定串接，水泥浆喷管、外加剂喷管、水喷管和气喷管穿过钻杆套管，下端分别连接通水泥浆管接头、外加剂管接头、水喷管接头和气喷管接头，使用时，将钻杆的上端与钻机固定连接，工作时可以调整喷射水泥浆和添加剂的混合比例，以达到更好的成孔质量。
