Abstract

The invention relates to the technical field of tunnel construction, and particularly relates to a steel sleeve launching device for shield engineering. The device is built on a shield shaft base plate and comprises a steel sleeve, an adjustable steel sleeve lifting mechanism, a steel sleeve counter-force supporting mechanism and a steel sleeve connecting mechanism for connecting an end part of the steel sleeve with a tunnel portal end wall, the adjustable steel sleeve lifting mechanism is horizontally built on the shield shaft base plate, the steel sleeve is horizontally welded right above the adjustable steel sleeve lifting mechanism, the steel sleeve counter-force supporting mechanism is built on the shield shaft base plate, the end of the steel sleeve counter-force supporting mechanism is in close contact with the tail end of the steel sleeve, the steel sleeve connecting mechanism is arranged on the tunnel portal end wall, and the steel sleeve is connected with the steel sleeve connecting mechanism. According to the device, the structure is simple, flexible adjustment can be conducted according to the practical situation during shield construction, the flexibility and the universality are high, when the steel sleeve is located and installed, the positioning stability and the firmness are high, and convenience is brought to shield construction.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a steel sleeve launching device for shield engineering. Background technique [0002] The steel sleeve receiving refers to a new receiving method adopted when the geological conditions of the receiving end of the shield are not good or the reinforcement is limited. The barrel remains sealed, and an earth pressure balance state is formed inside the steel sleeve to ensure smooth and safe receiving of the shield. [0003] In order to meet the needs of construction, the receiving device of the steel sleeve needs to be built on the bottom plate of the shield shaft, so that the end of the steel sleeve is connected with the portal, which is convenient for subsequent shield construction. [0004] The existing steel sleeve starting device has relatively low flexibility and versatility during positioning and installation, and its stability and firmness are relatively poor duri...
