Ultrahigh-pressure jet grouting drilling machine and application thereof in rotary jet grouting pile forming method
The invention discloses an ultrahigh-pressure jet grouting drilling machine and application thereof in a rotary jet grouting pile forming method. The ultrahigh-pressure jet grouting drilling machine comprises a crawler chassis, an upper vehicle chassis, a mast, a power head, a winch and a drilling tool system, wherein the upper vehicle chassis is arranged on the crawler chassis, the mast and the winch are arranged on the upper vehicle chassis, the power head is arranged on the mast in a sliding mode, the drilling tool system is installed on the power head, the power head is connected with thewinch through a steel wire rope, and connecting pieces are detachably arranged on the two sides of the power head. By means of the method, a large-diameter high-perpendicularity jet grouting pile canbe formed in a gravel-cobble stratum.
本申请公开了一种超高压喷射灌浆钻机及其在旋喷成桩方法中的应用，其中超高压喷射灌浆钻机包括履带底盘、上车底盘、桅杆、动力头、卷扬机及钻具系统，所述上车底盘设置在履带底盘上，所述桅杆、卷扬机设置在上车底盘上；所述动力头滑动设置在桅杆上，所述钻具系统安装在动力头上，所述动力头通过钢丝绳与卷扬机相联接；所述动力头两侧均可拆卸设置有连接件。本发明能够在卵碎石地层中形成大直径高垂直度的旋喷桩。
