Foundation reinforcing device with high pulling strength for rotary jet grouting drilling machine
The invention relates to a foundation reinforcing device with high pulling strength for a rotary jet grouting drilling machine. The foundation reinforcing device with high pulling strength for the rotary jet grouting drilling machine comprises a limiting barrel, and a plurality of permeation holes are formed in the outer side wall of the limiting barrel; the limiting barrel comprises a positioningcavity, an isolation cavity and an end cavity, the positioning cavity and the end cavity are located at the two ends of the isolation cavity in the length direction correspondingly, the inner diameter of the positioning cavity is larger than that of the isolation cavity, and the inner diameter of the isolation cavity is larger than that of the end cavity; a plurality of bearing columns are arranged in an inner cavity of the positioning cavity, and a positioning cone is arranged on the outer side wall of the positioning cavity; a top connecting plate is arranged on the outer side wall of the end cavity, and a positioning assembly is arranged between the top connecting plate and the positioning cavity; and a connecting assembly for limiting the position of the positioning cavity is arrangedon the positioning cavity. The foundation reinforcing structure has the effects that the anti-pulling strength of a concrete block body and the limiting barrel in the foundation is improved, and theposition stability and the punning property after the foundation is reinforced are effectively guaranteed.
本申请涉及一种高抗拔强度的旋喷钻机用地基加固装置，其包括限位筒体，所述限位筒体外侧壁设置有若干渗透孔；所述限位筒体包括定位腔体、隔离腔体和端部腔体，所述定位腔体和端部腔体分别位于隔离腔体长度方向的两端，所述定位腔体的内径尺寸大于隔离腔体的内径尺寸，所述隔离腔体的内径尺寸大于端部腔体的内径尺寸；所述定位腔体内腔设置有若干承接柱，所述定位腔体外侧壁设置有定位锥体；所述端部腔体外侧壁设置有顶接板，所述顶接板与定位腔体之间设置有定位组件；所述定位腔体上设置有用于限定定位腔体位置的连接组件。本申请具有提高混凝土块体及限位筒体在地基内的抗拔强度，有效保障地基加固后的位置稳定性及夯实性的效果。
