Shield machine synchronous grouting pipeline system and shield machine with same

Abstract

The invention discloses a shield machine synchronous grouting pipeline system and a shield machine with the same, belonging to the technical field of tunnel engineering. The system comprises multiple grouting pipelines; each grouting pipeline comprises a first grouting pipe, a gate valve, a fixing structure, a transition block and a second grouting pipe; the gate valve is detachably connected with one end of the first grouting pipe; the first grouting pipe is detachably mounted on the inner wall of the shield tail through the fixing structure; the transition block is arranged on the inner wall of the shield tail; a first connection hole and a second connection hole are arranged at the two ends of the transition block respectively and communicated with each other; the other end of the first grouting pipe is detachably connected with the first connection hole; one end of the second grouting pipe is connected with the second connection hole; and the other end of the second grouting pipe is communicated with a gap at the shield tail. According to the invention, since the first grouting pipe is detachably mounted on the inner wall of the shield tail through the fixing structure, the first grouting pipe can be independently dismantled for cleaning or replacement, the maintenance time of the grouting pipeline system is shortened, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a shield machine synchronous grouting pipeline system and a shield machine with the system. Background technique [0002] Shield tunnel boring machine, referred to as shield machine, is a special construction machine for tunnel boring, widely used in subway, railway, highway, municipal, hydropower and other tunnel projects. When the shield machine is used for tunnel excavation construction, because the excavation diameter of the cutter head of the shield machine is larger than the outer diameter of the segment, when the assembled segment ring comes out of the tail of the shield, a certain gap will be formed between the stratum and the segment. Building voids, if not filled in time, will cause ground subsidence and affect surrounding buildings. Therefore, the shield machine is usually equipped with a synchronous grouting pipeline system to inject grout into the gap syn...

AI Technical Summary

Problems solved by technology

[0005] Due to the long grouting pipe of the synchronous grouting pipeline system, a large amount of residue will accumulate and adhere for a long time, and the grouting pipe of the synchronous grouting pipeline system is buried in the shield tail structure and cannot be disassembled, so cleaning is very inconvenient and If the flushing is not thorough enough, it is easy to cause blockage of the synchronous grouting pipeline system

In addition, if the synchronous grouting pipeline system is damaged, it is inconvenient to replace because the grouting pipe is buried in the shield tail structure and cannot be disassembled
