Embodiment 2

[0033] Example 2, such as Figure 4 As shown, a muddy water shield mud pipeline extension device, the walking track 1 includes an upper slide rail 1-1 arranged on the upper part of the trailer 13 and a lower slide rail 1-2 arranged on the lower part of the trailer 13; the upper slide rail 1-2 1 corresponds to the lower rail 1-2 and is all matched with the running mechanism 2, that is, the upper sliding rail and the lower rail are all arranged in parallel with the trailer, and the running mechanism 2 can move along the upper sliding rail and the lower sliding rail. Such as Figure 5As shown, the running mechanism 2 includes a walking frame 2-6 and a driving device arranged on the walking frame 2-6, and the driving device provides power for the running frame to move along the upper slide rail and the lower rail. Walking frame 2-6 top is provided with upper traveling wheel 2-1 and upper limit wheel 2-3, and upper traveling wheel 2-1 and upper limit wheel 2-3 cooperate with upper...

Abstract

The invention discloses a mud pipeline extension device and an extension method of a mud-water shield, which solves the problems of inflexible use and short service life of the mud pipeline extension device in the prior art. The present invention includes shield machine mud pipes, mud hoses, walking frame mud pipes and tunnel mud pipes which are connected in sequence. The activity is set on the trailer, which is also equipped with a mud pipe crane for hoisting mud hard pipes. The invention adopts a walking frame with a simple structure, which moves along the track arranged on the side of the trailer, which reduces the occupation of the trailer space; the mud hose does not directly contact the trailer, and the outer layer of the hose does not wear out, prolonging the service life of the mud hose . In addition, the slurry pipeline extension device of the mud-water shield of the present invention is not limited by the turning radius of the tunnel and is suitable for mud-water shields with large and small diameters. It has simple structure, flexible operation, wide application range and convenient maintenance.

Description

technical field [0001] The invention relates to the field of mud-water shield technology, in particular to a mud-water shield mud pipeline extension device and an extension method. Background technique [0002] With the rapid development of shield machine manufacturing level and shield construction technology, more and more tunnel projects are constructed by 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 interference with the soil around the excavation surface. It is widely used in tunnels with high water pressure, shallow covering soil and unstable ground. excavation. The mud pipeline is the only way to discharge slag from the mud-water shield. Since the mud pipeline requires good wear resistance and strong pressure bearing capacity, the mud pipeline is mostly made of steel seamless steel pipes. The mud pipeline is divided into two parts, one part is fixedl...
