Stirring shaft for cement mixing pile construction, construction device and construction method
The invention discloses a stirring shaft for cement mixing pile construction, a construction device and a construction method, and belongs to the technical field of cement mixing piles. The stirring head is connected to the tail part of the stirring hollow shaft; a slurry conveying pipe and a gas conveying pipe which extend to the stirring head are arranged in the stirring hollow shaft; a slurry spraying nozzle communicated with the slurry conveying pipe is mounted on the stirring head, and the end part of the slurry spraying nozzle extends out from the circumferential direction of the stirring head; a telescopic air pipe and an air bag are mounted at the tail of the air pipe; a one-way movable door which can only be opened from the interior of the stirring head is arranged at the bottom of the stirring head; the air bag is pressurized through the air conveying pipe, the cement soil of the whole pile body is compacted through expansion and enlargement of the air bag, the strength of the cement soil mixing pile is improved, transverse pressure on soil around the pile can be generated through pressurization of the air bag, the mixing pile and soil between the piles are better connected together, and the bearing capacity of the cement soil and the cement soil mixing pile is improved.
本发明公开了一种水泥土搅拌桩施工用搅拌轴及施工装置和施工方法，属于水泥土搅拌桩的技术领域，搅拌轴包括搅拌空心轴和搅拌头；搅拌头连接在搅拌空心轴的尾部；搅拌空心轴的内部设有延伸至搅拌头的输浆管和输气管；搅拌头上安装有与输浆管相连通的喷浆嘴，喷浆嘴的端部从搅拌头的周向伸出；输气管的尾部安装有伸缩气管和气囊；搅拌头的底部设有仅能从搅拌头内部开启的单向活动门；利用输气管对气囊进行加压，并利用气囊的膨胀变大，实现整个桩身水泥土的压密，提高了水泥土搅拌桩的强度，且气囊加压还能产生对桩周土体的横向压力，使搅拌桩和桩间的土更好的连接在一起，提高了水泥土和水泥土搅拌桩的承载力。
