Dry-process vibroflot

Abstract

The invention relates to a dry-process 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 air inlet; 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 soft ground by a vibration method, in particular to a dry method vibrator. Background technique [0002] Vibro technology is also called vibro method, and can be divided into vibro compaction method and vibro replacement method or vibro gravel pile method according to different ways and means of strengthening loose and soft soil. The vibrating method is to lift the vibrator by a crane, start the submersible motor to drive the eccentric block, so that the vibrator produces high-frequency vibration, and at the same time start the high-pressure water pump, so that the high-pressure water is ejected from the nozzle. Gradually sinks to design depth. After the hole is cleared, gravel is filled into the hole step by step from the ground. [0003] The vibrator is the main construction equipment in the vibro-construction method. At present, the most widely used vibrator in China is the electric vibrator or the ...

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.
