Device for forming discrete material pile by vibrating immersed tube

Abstract

A device for forming a discrete material pile through a vibration immersed tube comprises a vibration hammer and the immersed tube, and the immersed tube comprises a steel tube, a cavity, a connecting rod, a check valve, a discharging port, a steel chisel and a feeding port which are connected and matched with one another; a lower port of the steel pipe is provided with a check valve to form a discharge port; a steel chisel is arranged in the steel pipe, one end of a chisel head of the steel chisel extends out of the lower end of the steel pipe, namely the discharge port, and the steel chisel and the steel pipe are fixed through a connecting rod; and the check valve is attached to the drill bit groove of the steel drill so as to seal the discharge port. The utility model further discloses a method for forming the discrete material pile by using the device, the impact force of the vibratory hammer is utilized, the immersed tube is driven into the foundation, the discrete materials such as gravels are placed in the cavity of the immersed tube through the feed port, the immersed tube is pulled upwards and vibrated, the gravels fall into the hole of the foundation through the discharge port, and the discrete material pile is formed. The vibration tube sinking device effectively solves the problem that tube sinking is difficult under the condition that a stone filling layer exists in a foundation in an existing vibration tube sinking process.
