Low-clearance soft foundation treatment construction device
A low-clearance soft foundation treatment construction device belongs to the field of soft foundation treatment, and is characterized in that a drill rod is mounted and dismounted at an enclasping device, a fixed wing provided with a counter-force wing is mounted in a drill bit connected with the drill rod, the fixed wing is meshed with a conical gear of a rotary cutter shaft, a core rod is connected with the fixed wing through a bearing, and a grouting (gas) pipe is mounted in the core rod; two ends of the shell are respectively connected with the core rod and the fixed wing; the method has the advantages that the clearance height is low, and construction can be conducted under the height limiting condition; the mechanical arm automatically loads and unloads the drill rod, the fixed wing is in single-action connection with the drill bit through a bearing, the rotary cutting blade and the three-wing stirring blade conduct vertical cross stirring under the action of the counter-force wing, the gas pipe conducts gas explosion on the stirring soil body, the soil body and a curing agent are mixed more evenly, adaptability to complex stratums is improved, and the strength and integrity of a pile body are improved. The pile forming quality is greatly improved; the curing agent is small in mixing amount and low in construction cost, and the engineering cost is remarkably reduced.
一种低净空软基处理施工装置，属软基处理领域，它的钻杆在抱紧装置处安装、拆卸，与钻杆连接的钻头内安装设有反力翼的固定翼，固定翼与旋切刀轴锥形齿轮啮合，芯杆通过轴承与固定翼连接，芯杆内安装注浆(气)管，外壳两端分别与芯杆和固定翼连接，钻头底部芯杆上连接搅拌叶片。本发明的优点：净空高度较低，可在限高条件下施工；机械臂自动装卸钻杆，固定翼与钻头通过轴承单动连接，在反力翼作用下旋切叶片与三翼搅拌叶片立体交叉搅拌，气管向搅拌土体中进行气爆，使得土体与固化剂拌和更加均匀，提高对复杂地层的适应性，有利于提高桩身强度和完整性，大幅提升成桩质量；固化剂的掺量小，施工费用低，显著降低工程成本。
