Rotary jet grouting waterproof curtain construction device under water-rich sandy gravel geological condition
The invention relates to a rotary jet grouting waterproof curtain construction device under the water-rich sandy gravel geological condition, and belongs to the technical field of rotary jet grouting waterproof curtains. The rotary jet grouting waterproof curtain construction device comprises a fixing frame, a lead screw rotationally mounted in the fixing frame and a connecting disc in threaded connection with the peripheral side of the lead screw; a shell is rotationally mounted at the bottom of the connecting disc; a slag feeding pipe is arranged in the machine shell in a downward penetrating mode in the vertical direction; a rotary excavating base plate is fixed to the bottom end of the slag feeding pipe, and a threaded pipe in threaded connection with the lead screw is rotationally mounted in the connecting disc; the bottom end of the threaded pipe is fixedly connected with the top of the machine shell; a first supporting disc is vertically and slidably connected to the peripheral face of the slag feeding pipe, a first spring is fixed to the top of the first supporting disc, and the top end of the first spring is fixedly connected with the inner top face of the machine shell; a first top supporting rod is fixed to the top of the first supporting disc; a first sliding piece is slidably connected into the connecting disc in the radial direction of the connecting disc; the first sliding piece is used for being inserted into the peripheral face of the threaded pipe; and a limiting mechanism used for limiting the first sliding piece is arranged in the connecting disc. The rotary jet grouting waterproof curtain construction device under the water-rich sandy gravel geological condition has the effect of conveniently controlling the volume of the muck in a rotary drilling machine.
本申请涉及富水砂卵石地质条件下旋喷止水帷幕施工装置，属于旋喷止水帷幕的技术领域，其包括固定架、转动安装于固定架内的丝杠以及螺纹连接于丝杠周侧的连接盘；连接盘底部转动安装有机壳；机壳内沿竖向向下贯穿设置有上渣管；上渣管底端固定有旋挖底盘，连接盘内转动安装有与丝杠螺纹连接的螺纹管；螺纹管底端与机壳顶部固定连接；上渣管外周面沿竖向滑移连接有撑盘一，撑盘一顶部固定有弹簧一，弹簧一顶端与机壳内顶面固定连接；撑盘一顶部固定有顶撑杆一；连接盘内沿自身径向滑移连接有滑移件一；滑移件一用于与螺纹管外周面插接；连接盘内设置有用于对滑移件一进行限位的限位机构。本申请具有便于控制旋挖机内的渣土容量的效果。
