Spiral unearthed following jacking pipe curtain machine

Abstract

The invention relates to a spiral unearthed following jacking pipe curtain machine comprising a pipe curtain drill and a drilling real-time guide and correction system. The pipe curtain drill comprises a jacking cylinder supplying the short stroke and a transmission motor and a transmission chain which supply the long stroke; the drilling real-time guide and correction system comprises a drill direction display light source, a camera, a display and a drilling correction device; the display processes rotation position images, of the drill direction display light source and drilling correction device, captured by the camera and outputs the drilling direction deviation; the drilling correction device corrects the deviation in a rotating manner according to the drilling direction deviation and the own rotation position. The system is capable of tracking and correcting the deviation of the drilling trace in real time, the jacking accuracy is improved, and double drive power is provided for pipe curtain steel pipe jacking through the combination of the jacking cylinder of the short stroke and transmission motor of the long stroke; the double power is provided for the pipe curtain steel pipe jacking through the jacking cylinder and the transmission motor, the operating efficiency is improved, and the construction can be performed rapidly and efficiently.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a spiral excavation and pipe jacking pipe curtain machine. Background technique [0002] With the development of the country's economy and the increase of urban population density, the space that can be developed on the ground is less and less, and the development of underground space is an inevitable trend in the development of international metropolises. Urban tunnel projects, especially underground railways and highway tunnels that solve urban traffic congestion And various underground passages, civil air defense passages, underground common trenches, etc. have emerged in large numbers. [0003] The pipe curtain method is a new type of underground engineering underground excavation technology. It is a construction method for constructing large-span and large-section underground excavation projects on the basis of small-diameter steel pipe densely packed...
