Vibroflot

Abstract

The invention relates to a vibroflot for compacting soft foundation by a vibroflotation method. The dry-process vibroflot comprises a vibroflotation head, a body and a motor gland, wherein the top of the body is connected with the vibroflotation head, while the tail is connected with the motor gland; an air-water channel, a water outlet channel and a water return channel are formed in the body; the motor gland is provided with an air inlet, a water inlet and a water return hole; the vibroflotation head is provided with a water outlet; the air-water channel is connected with an airinlet; the water outlet channel is connected with the water outlet; and the water return channel is connected with the water return hole. High pressure air is sprayed through the air-water channel, the water and air are mixed to impact the ground, and the pore forming rate is higher; the water outlet channel and the water inlet channel are self-circulated under certain pressure and water resources are saved; and water or air can pass through the air-water channel, so that a range of regulating the ground impacting pressure of the vibroflot is wider.

Description

Technical field [0001] The invention relates to a device for encrypting a soft foundation by a vibration method, in particular to a vibrator. Background technique [0002] The vibro-impact technique is also called the vibro-impact method. According to the different ways and means to strengthen the soft soil, it can be divided into the vibro-compacting method and the vibro-replacement method or the vibro-impact stone pile method. The vibrating method is to lift the vibrator by a crane, start the submersible motor to drive the eccentric mass, and make the vibrator produce high-frequency vibration. At the same time, the high-pressure water pump is turned on to make the high-pressure water ejected from the nozzle. Gradually sink to the design depth. After the hole is cleared, the gravel is filled in the hole from the ground. [0003] The vibrator is the main construction equipment in the vibro-percussion method. At present, the most widely used vibrator in China is an electric vibrat...

AI Technical Summary

Problems solved by technology

[0004] Existing vibrofloors mainly use high-pressure water jets to flush and vibrate the ground. However, the disadvantages of only water flushing are very obvious. It not only wastes a lot of water, but also produces a lot of mud. The discharged mud pollutes the surrounding environment and brings inconvenience to the construction.

Moreover, high pressure and a large amount of water will cause a large amount of sand to be deposited at the orifice, causing the construction ground to rise, which will bring inconvenience to the post-processing. At the same time, it will easily cause the phenomenon of "string holes" and poor construction quality.
