Embodiment 1

[0060] like figure 1 , figure 2 , image 3 As shown, the tunnel excavation construction method includes the construction method of extending the pipeline of the shield machine outside the tunnel, and the construction method of the pipeline extension of the shield machine outside the tunnel, including the steps:

[0061] Arrange the pipeline extension device 9 at the tunnel entrance; figure 1 The middle dotted line box represents the tunnel inlet position, the pipeline extension device 9 is a long hose type pipeline extension device, and has a pipeline extension device feeding and discharging pipe 10. The slurry pipe and the slurry discharge pipe, the slurry feeding and discharging pipe of the pipeline extension device 9 adopts a long hose, and the long hose is bent and arranged on the horizontal platform at the entrance of the tunnel, and the slurry feeding and discharging pipe adopts the upper and lower double-layer arrangement;

[0062] An in-tunnel pipeline transmission...

Embodiment 2

[0076] The difference between this embodiment and Embodiment 1 is that, in Embodiment 1, the slurry feeding and discharging pipeline is suspended on the side wall of the tunnel. In this embodiment, the slurry feeding and discharging pipelines are suspended on the top wall of the tunnel.

Embodiment 3

[0078] The difference between this embodiment and the above embodiments is that in Embodiment 1, the suspension trolley includes a manual hoist, and the manual hoist is suspended on the body of the suspension trolley. In this embodiment, the suspension trolley includes a rigid rod with a fixed length. One end of the rigid rod is connected to the body of the suspension trolley, and the other end is connected to the pipe clamp. The suspension heights of the slurry feed pipe and the slurry discharge pipe are not adjustable. In other embodiments, the pipe clamp can also be connected to the body of the suspended trolley through a wire rope with a certain length.

Abstract

The invention relates to a tunnel outer shield tunneling machine pipeline extension construction method and a tunnel tunneling construction method.The tunnel tunneling construction method comprises the tunnel outer shield tunneling machine pipeline extension construction method, and the tunnel outer shield tunneling machine pipeline extension construction method comprises the steps that a long hose type pipeline extension device is arranged at a tunnel inlet; the slurry inlet pipe and the slurry discharge pipe are arranged in parallel in the vertical direction; an in-tunnel pipeline conveying device is arranged in a tunnel, the in-tunnel pipeline conveying device comprises a sliding rail and a hanging trolley movably installed on the sliding rail, and the hanging trolley tightly holds a slurry inlet pipe and a slurry outlet pipe on the in-tunnel pipeline conveying device through a pipe clamp and enables the slurry inlet pipe and the slurry outlet pipe to be arranged in parallel in the vertical direction; the shield tunneling machine drives the slurry feeding and discharging pipeline to extend into the tunnel during tunneling construction, and pipeline splicing operation is carried out after the slurry feeding and discharging pipeline extends by a distance of a pipe replacement stroke; the pipelines are arranged in an up-and-down double-layer mode, the slurry feeding and discharging long hoses move independently and do not interfere with each other, and meanwhile the slurry feeding and discharging pipelines can be arranged flexibly.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to the pipeline extension construction of shield tunneling machines, and in particular to a construction method for extending the pipeline of shield tunneling machines outside a tunnel and a tunnel tunneling construction method. Background technique [0002] With the rapid development of shield machine manufacturing level and shield construction technology, more and more tunnel projects are constructed using shield machines. Slurry shield is a kind of shield machine. It has the advantages of fast excavation speed, high precision of surface settlement control, and little disturbance to the surrounding soil of the excavation surface. It is widely used in high water pressure, shallow overburden and unstable ground tunnels. of excavation. The mud pipeline is the only channel for the slag discharge of the mud-water shield. The circulating pipeline is formed by the slurry inlet ...
