Problems solved by technology
But in fact, due to the fixed structure between the beam and the lifting column of the hopper, when the lifting hopper reaches 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 and pouring into the collecting hopper filler

The invention provides a pressurizing vibroflotation method which comprises the following steps: compressed air is introduced into a blanking pipe in the vibroflotation device for pushing a filling material in the blanking pipe to discharge from the downside outlet of the blanking pipe. The invention further provides pressurizing vibroflotation equipment fit for the vibroflotation method. A pressurizing sealing device is added in the conventional vibroflotation device, wherein the pressurizing sealing device comprises an air injection chamber; a compressed air inlet pipe is arranged on the air injection chamber; and a valve is arranged on the inlet pipe. The pressurizing sealing device further comprise a depressurizing channel to enable the air injection chamber to communicate with air; a reducing valve is arranged on the channel; the air injection chamber is connected with the blanking pipe through a valve; a material collecting hopper is connected with the blanking pipe through the pressurizing sealing device; and a discharging valve is arranged on the blanking channel between the air injection chamber and the material collecting hopper. The method is easy and feasible and highly reliable. The pressurizing vibroflotation device has a reasonable structure, provides a reliable assurance for the pressurizing vibroflotation method and is easy to operate.
Description
technical field [0001] The invention relates to vibrating technology and provides a pressurized vibrating method. Also provided is a pressurized vibrate device with a bottom discharge device used in the pressurized vibrated method. Background technique [0002] In the prior art, a vibrating device with a bottom discharge device used for foundation reinforcement or underwater deep layer encryption includes a feeding pipe, a vibrator is fixed at the lower end of the feeding pipe, and a vibrating device is fixed at the upper end of the feeding 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 collecting hopper and the feeding pipe in the prior art are both open and non-sealed structures. There are difficulties in the use of this vibro-shock device in gr...
