Soft soil foundation reinforcing device based on gravel piles and reinforcing method thereof
The invention provides a gravel pile-based soft soil foundation reinforcing device, which is vertically arranged on a vibroflot construction pile frame, is used for carrying out vibroflot construction on soft soil, and comprises a guide pipe, a vibration seat, a vibration body and a vibration head which are connected in sequence, the vibration seat is rotatably connected with the vibration body, a first driving device is arranged in the vibration seat, and the first driving device is used for driving the vibration body to rotate; the vibration body comprises a butt joint pipe and a vibration sleeve which are sequentially connected, the butt joint pipe sleeves the vibration seat and is rotationally connected with the vibration seat, and one end, away from the butt joint pipe, of the vibration sleeve is connected with the vibration head; a guide cavity is formed in the vibration sleeve in a penetrating mode in the direction perpendicular to the axis of the butt joint pipe, a first top sleeve and a second top sleeve which are in butt joint are slidably arranged in the guide cavity, butt joint openings are formed in the ends, close to each other, of the first top sleeve and the second top sleeve, and the end, close to the first top sleeve, of the second top sleeve is slidably arranged in the first top sleeve; the problems that the size of a manufactured gravel pile is limited, the construction efficiency is low and the like due to the fact that the vibration density range of a traditional vibroflot is limited are solved.
本发明提供了一种基于碎石桩的软土地基加固装置,竖向设置在振冲器施工桩架上，用于对软土地进行振冲施工，包括依次连接的导管、振座、振体和振头，振座与振体转动连接，振座内设置有第一驱动装置，第一驱动装置用于驱动振体转动；振体包括依次连接的对接管和振套，对接管套设在振座上并与振座转动连接，振套远离对接管的一端与振头连接；振套沿垂直于对接管轴线的方向贯穿开设有导向腔，导向腔内滑动设置有相互对接的第一顶套和第二顶套，第一顶套与第二顶套相互靠近的一端均开设有对接口，第二顶套靠近第一顶套的一端滑动置于第一顶套内；其解决了传统振冲器的振密范围有限，导致制作的碎石桩的体积有限，而且施工效率低下等问题。
