Embodiment 1

[0046] Embodiment 1. When using the present invention, the slurry shield machine includes the same upper and lower sets of mud pipe extension devices, which correspond to the slurry feeding system and the slurry discharge system respectively. The following takes one of the extension devices as an example to illustrate, and simultaneously establishes Such as figure 1 In the Cartesian coordinate system shown, the negative direction of the z-axis is the same as the tunneling direction.

[0047] The mud pipe extension device consists of the following modules: drive mechanism 1, telescopic pipe 2, hinged pipe 3, hinged mechanism 4, trailer mud pipe 5, tunnel mud pipe 6, extension pipe 7, expansion joint 8, trailer one 9, trailer two 10 , the first trailer 9 and the second trailer 10 are hinged to provide a fixed platform for the entire mud pipe extension device. In addition, during tunnel excavation, uphill, downhill and horizontal turning conditions are often encountered, such as...

Embodiment 2

[0053] Embodiment 2, a construction method of a mud pipe extension device, including the tunneling state of the shield machine and the extension state of the mud pipe:

[0054] (1) Tunneling state of the shield machine: the driving mechanism 1 does not provide power, the driving trolley 104 and the hinged pipe 3 connected to it are stationary relative to the inner wall of the tunnel, but the driving trolley 104 and the hinged pipe 3 connected to it are relative to the trailer one 9 and the two trailers The z axis moves in the positive direction. At the same time, the inner cylindrical section 202 of the telescopic tube 2 is gradually pulled out relative to the outer cylindrical section 201 .

[0055] (2) Mud pipe extension state: when the inner cylinder section 202 in the telescopic pipe 2 reaches the full stroke state relative to the outer cylinder section 201, as attached figure 2 , Figure 4 As shown, it is necessary to stop the tunneling of the shield machine. The tunn...

Abstract

The invention discloses a mud pipe extension device and a construction method thereof, which solves the technical problem that the existing mud pipe extension device has strong pertinence but poor versatility. The invention includes a telescopic pipe connected between the mud pipe of the trailer and the mud pipe of the tunnel, through which the telescopic pipe is cyclically expanded and contracted, and an extension pipe is conveniently added between the mud pipe of the trailer and the mud pipe of the tunnel, and the telescopic pipe is connected with at least two trailers through a hinge mechanism At the same time, the pitch hinge and yaw hinge are hinged, and the adjacent trailers are hinged to realize the up and down rotation and lateral rotation of the mud pipe to meet the needs of the shield machine for uphill and downhill and turning. The invention has compact structure, strong versatility, can be adapted to tunnels of different diameter series, is easy to operate, has a high degree of automation, and has the characteristics of high-efficiency and humanized tunnel construction operations. A single telescopic tube adopts a structure with both ends hinged, which can adapt to the working conditions of the shield machine up and down slopes and horizontal turns during construction, and meets the excavation requirements of non-linear tunnels.

Description

technical field [0001] The invention relates to the technical field of mud pipeline extension for mud-water shield tunneling, in particular to a mud pipe extension device and a construction method thereof. Background technique [0002] Shield method tunnel construction plays an increasingly widespread role in transportation, water conservancy, electric power, and municipal construction. With the progress of the times, shield method tunnel construction is constantly developing in the direction of safety, efficiency and high reliability. [0003] The slurry shield machine is a kind of shield tunneling equipment, and the slurry pipe extension device is an indispensable system. At present, the commonly used mud pipe extension device is to reserve a certain length of hose on the top of the trailer to meet the need for the mud pipe to move forward during shield tunneling. When the pipeline needs to be extended, the pipeline extension operation is completed by moving the walking f...
