Problems solved by technology
Moreover, under the condition of a relatively flat cross-sectional shape, the space inside the tunnel is narrow, and it is difficult to adjust the attitude of the long segment in the tunnel by single-point hoisting.
It can be seen that the single-segment attitude transportation method adopted in the circular shield tunnel construction cannot meet the transportation requirements of the rectangular shield tunnel segment in the tunnel

The present invention proposes a transport method for segments in a rectangular shield tunnel, which can realize the transport operation of various types of rectangular shield tunnel segments in the tunnel, changing the segment transport method in the prior art that can only carry out a single type The segment transportation operation can transport different types of segments to the corresponding position of the tablet feeder in the correct posture, meeting the needs of the normal operation of the tablet feeder. In addition, it is not only suitable for transporting general types of rectangular shield tunnel segments, but also suitable for transporting segments in rectangular shield tunnels where the aspect ratio is small and the cross-sectional shape is relatively flat, and conventional segment transport methods cannot be applied. .
Description
technical field [0001] The invention relates to the technical field of rectangular shield tunneling, and mainly relates to a method for transporting segments in a rectangular shield tunnel. Background technique [0002] The purpose of segment transportation in the shield tunnel is to transport the segments outside the tunnel to the inside of the tunnel through the segment transport vehicle running inside the tunnel and place the segments on the feeding segment by the hoisting machinery inside the shield tunnel. on board. The overall dimensions of the segments of a circular tunnel are generally relatively small, and the assembly machine of the circular shield machine has low requirements on the posture of the segments when grabbing the segments. In the tunnel, all segments can be assembled with one segment posture. Transportation operations in tunnels, such as figure 1 and figure 2 shown. Please refer to figure 1 , the segment transport vehicle 6 transports all the segm...
