Stirring pile slurry and gas integrated mixing and spraying structure and construction technology
The invention discloses a mixing pile slurry and gas integrated mixing and jetting structure and a construction technology, and relates to the technical field of pile foundation construction. Comprising a connector, an air inlet pipe and a slurry inlet pipe, the top of the connector communicates with a slurry inlet pipe and an air inlet pipe, the bottom of the connector is rotationally connected with a drill rod, and the slurry inlet pipe and the air inlet pipe communicate with a cavity in the drill rod. A feed port of the slurry inlet pipe is connected with a mortar pump through a slurry conveying pipe, and a feed port of the mortar pump is connected with a cement pool; an air inlet of the air inlet pipe is connected with an air compressor through an air supply pipe; a driving device is further arranged, and the driving device is arranged below the connector and used for driving the drill rod to rotate. According to the invention, independent air injection, independent guniting or integrated slurry and air injection can be realized, the stirring uniformity of a stirring pile can be improved, the pile forming effect is ensured, the cement slurry consumption is saved, the engineering investment is saved, the drilling and stirring capacity in a silt hard layer can be effectively improved, and the working efficiency is improved.
本发明公开了一种搅拌桩浆气一体混合喷射结构及施工工艺，涉及桩基施工技术领域。包括连接头、进气管和进浆管；连接头顶部分别连通有进浆管和进气管，底部转动连接有钻杆，进浆管和进气管与钻杆内的空腔连通；进浆管的进料口通过送浆管与灰浆泵连接，灰浆泵的进料口与水泥池连接；进气管的进气口通过送气管与空压机连接；还设置有驱动装置，所述驱动装置设置于所述连接头下方，用于驱动钻杆转动。本发明可以单独喷气、单独喷浆或者浆气一体喷射，能提高搅拌桩的搅拌均匀性，确保成桩效果的同时节约水泥浆用量，节约工程投资，并能有效改善在粉砂硬层中的钻进搅拌能力，提高工作效率。
