Vibroflotation equipment with bottom discharge device and method for underwater vibroflotation

Abstract

The invention provides vibroflotation equipment with a bottom discharge device. A feed pipe is a telescopic duct with adjustable length and comprises an inner sleeve and an outer sleeve; the inner sleeve and the outer sleeve are arranged in the manner that the inner sleeve or the outer sleeve are arranged on the upper side; a segment of the inner sleeve and a segment of the outer sleeve at the adjacent ends are sleeved together; and a point at which the inner sleeve is sleeved with the outer sleeve is provided with a hydraulic clutch device. The invention provides a method for underwater vibroflotation by means of the vibroflotation equipment. The method comprises the following steps of: pushing the feed pipe against the water bottom; arranging fillers in the feed pipe; and performing vibroflotation to form pores. According to the vibroflotation equipment and the method, the problem that the feed pipe is not long enough when used in deep water is conveniently solved, and the feed pipe is pushed against the water bottom to solve the problem of preventing the fillers from floating away.

Description

technical field [0001] The invention relates to a vibrating equipment, in particular to a vibrating equipment with a bottom discharge device. The invention also provides a method for using the vibrating equipment to perform underwater vibrating. Background technique [0002] Vibration equipment with a bottom discharge device used for foundation reinforcement or underwater deep layer encryption in the prior art includes a feed pipe, a vibrator is fixed at the lower end of the feed pipe, and a vibrator is fixed at the upper end of the feed pipe. A collecting hopper is arranged, and the collecting hopper is connected with a lifting pulley, which is connected with the pulley block arranged on the upper end of the pile or mast through a wire rope and connected with a winch, so that the lowering pipe is lifted. The feeding pipes in the prior art are all fixed lengths, and such feeding pipes have the following disadvantages: when the height of the pile or mast is limited, and the ...

AI Technical Summary

Problems solved by technology

The feeding pipes in the prior art are all fixed lengths, and such feeding pipes have the following disadvantages: when the height of the pile or mast is limited, and the height of the restricted feeding pipe is less than the length of the feeding pipe used for vibrating, It will bring difficulties to vibrating operation

The disadvantage of this structure is that due to the fixed structure between the beam and the lifting column of the hopper, when the lifting hopper is raised to the same height as the collecting hopper, the distance between the lifting hopper and the collecting hopper prevents the lifting hopper from leaning against the collecting hopper to the collecting hopper. Filling material is poured into the hopper
