Station crossing device and method for shield tunneling machine

Abstract

The invention discloses a station crossing device for a shield tunneling machine. The station crossing device comprises a bracket, a piston mechanism and a jacking mechanism; the bracket is used for receiving and bearing the shield tunneling machine and serves as a reaction frame used when the shield tunneling machine starts tunneling, the piston mechanism comprise a piston component connected with the shield tunneling machine and the bracket and is used for horizontal moving between shield tunneling machine and the bracket, and the jacking mechanism comprises a jacking component connected to the shield tunneling machine and is used for jacking the shield tunneling machine and the bracket to be separated from a foundation. By applying the device, self-waling movement of the shield tunneling machine and the bracket is achieved by means of cooperation movement of the piston mechanism and the jacking mechanism, and a roller steel plate structure or a rail transportation structure which can enable the bracket to move does not need to be arranged for the bracket separately; meanwhile, after the shield tunneling machine crosses a station, the bracket directly serves as the reaction starting frame of the shield tunneling machine, the piston mechanism supports the shield tunneling to tunnel forwards, and the reaction starting frame does not need to be installed independently. The device is simple in structure and easy and convenient to operate, the station crossing working difficulty of the shield tunneling station is greatly reduced, the working time is shortened, the construction efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a station passing device and method for a shield machine. Background technique [0002] In the construction of urban subway tunnels, shield machines play an increasingly important role. After the shield machine completes the construction of a section, it needs to move through the subway station—referred to as the shield passing through the station to construct the next section tunnel. [0003] Currently, there are two commonly used methods for the passing of the existing shield machine: a. During the passing of the shield machine, a trailer is used to carry the shield machine, a roller is placed on the bottom of the trailer, and a steel plate is laid under the roller. Rolling on the steel plate makes the trailer move forward. The disadvantage is that the moving speed is relatively slow. After the shield machine passes through the station, it must be moved to the count...

[0003] Currently, there are two commonly used methods for the passing of the existing shield machine: a. During the passing of the shield machine, a trailer is used to carry the shield machine, a roller is placed on the bottom of the trailer, and a steel plate is laid under the roller. Rolling on the steel plate makes the trailer move forward. The disadvantage is that the moving speed is relatively slow. After the shield machine passes through the station, it must be moved to the counter force starting frame to provide support counter force for its tunneling. The work is difficult and the construction period is slow; b. Install the wheels on the trailer and set up the track to make the trailer move forward along the track. Although its movement is stable and reliable, and the moving speed is fast, the shield machine still needs to be moved up again to provide support for its tunneling after passing the station. The reaction starting frame of the reaction force is difficult to work and the construction period is slow
