Problems solved by technology

When the mud shield machine is working, the mud pipe in the tunnel needs to be connected once every time it is excavated 6m-10m. Mud pollution, manual cleaning is time-consuming and laborious
[0003] At present, the commonly used pipe extension devices generally use mud tanks to collect sewage. This collection method requires repeated transportation of sewage, which cannot really solve the problem of mud leakage. Moreover, mud will gradually accumulate inside the sewage tank, and it is very difficult to clean up. trouble
In addition, there is also a three-way ball-type pipe extension device. This device has high requirements for the production of the three-way valve and the blocking ball. Cavity is easy to be blocked and other problems

Abstract

The invention discloses a shield machine pipe extension device and a connection method for a slurry pipeline in a tunnel. The device comprises a three-way pipe with a first port, an outer sleeve pipewith one end connected with the first port, a telescopic pipe with one end telescopically inserted and stretches into the three-way pipe from the other end of the outer sleeve pipe, a sealing elementarranged between the telescopic pipe and the outer sleeve pipe, a driving device for driving the telescopic pipe to move and a blocking ball capable of entering or disengaging from the telescopic pipeunder the effect of pressure. The three-way pipe is further provided with a second port which is connected with the slurry pipeline of a shield machine in a blocking manner, and a third port which isconnected with the slurry pipeline in the tunnel in a disengaging manner. According to the shield machine pipe extension device and the connection method for the slurry pipeline in the tunnel, slurrydoes not need to be transported backwards, the mechanism is simple, the economy is good, and operation and maintenance are convenient.

Description

technical field [0001] The invention relates to a shield machine pipe extension device and a mud pipe connection method in a tunnel, belonging to the field of mud-water shield machines for tunnel construction. Background technique [0002] The slurry shield machine has been widely used in the construction of subway tunnels and cross-river and sea-crossing tunnel projects. When the mud shield machine is working, the mud pipe in the tunnel needs to be connected once every time it is excavated 6m-10m. Mud pollution, manual cleaning up time-consuming and laborious. [0003] At present, the commonly used pipe extension devices generally use mud tanks to collect sewage. This collection method requires repeated transportation of sewage, which cannot really solve the problem of mud leakage. Moreover, mud will gradually accumulate inside the sewage tank, and it is very difficult to clean up. trouble. In addition, there is also a three-way ball-type pipe extension device. This devi...
