Mud-water shield mud pipeline extension device and extension method

Abstract

The invention discloses a mud-water shield mud pipeline extension device and an extension method. The mud-water shield mud pipeline extension device and the extension method solve the problems of inflexible use and short service life of a mud pipeline extension device in the prior art. The mud-water shield mud pipeline extension device comprises a shield machine mud hard pipe, a mud hose, a walking frame mud hard pipe and a tunnel mud hard pipe which are sequentially connected. The walking frame mud hard pipe is movably arranged on a trailer through a walking mechanism. The mud hose is movablyarranged on the trailer through a sliding part. A mud pipe crane for hoisting the mud hard pipe is arranged on the trailer. According to the mud-water shield mud pipeline extension device and the extension method, a walking frame of a simple structure is adopted and moves along the track arranged on the side face of the trailer, and the occupation of the space of the trailer is reduced; the mud hose is not in direct contact with the trailer, the outer layer of the hose does not wear, and the service life of the mud hose is prolonged. In addition, the mud-water shield mud pipeline extension device is not limited by the tunnel turning radius and is suitable for mud-water shields with the large or small diameters, the structure is simple, the operation is flexible, the application range is wide, and the maintenance is convenient.

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...
