Abstract

The invention discloses a spewing prevention device, a use method thereof and a spiral conveyor. The spewing prevention device is used for preventing the spiral conveyor from spewing in the tunnelingprocess of a soil pressure balance shield machine, and comprises a residual soil conveying pipeline connected with the output end of the spiral conveyor, a near-end gate valve mounted on the conveyingpipeline and used for controlling the spiral conveyor to discharge residual soil into the residual soil conveying pipeline, an air source connecting structure mounted on the residual soil conveying pipeline and used for being connected with an air source generating device, and a far-end gate valve mounted on the residual soil conveying pipeline and located in the output direction of the air source connecting structure. The air source generating device conveys compressed air into the residual soil conveying pipeline towards the far-end gate valve through the air source connecting structure toprovide residual soil conveying power for conveying residual soil into a residual collecting device of a shield tunneling machine. According to the spewing prevention device, part of residual soil located at the output end of the spiral conveyor is discharged, the pressure of the residual soil at the output end of the spiral conveyor is lowered to prevent spewing.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to an anti-spray device and a method of use thereof for preventing spewing of a screw conveyor when an earth pressure balance shield machine is excavating, and also to a screw conveyor. Background technique [0002] The earth pressure balance shield machine is simple to discharge soil, has strong reliability and strong applicability, and is widely used in urban subway rail transit tunnel projects. Warehouse, segment assembly machine, synchronous grouting system and shield tail sealing device etc. Among them, the screw conveyor is one of the key components of the earth pressure balance shield machine, and it is the soil discharge device of the shield machine, which is composed of a cylinder, a driving device, a screw shaft, and a slag discharge gate. [0003] During shield tunneling construction, geological conditions, hydrological conditions, and tunneling par...
