Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing:

[0010] Such as figure 1 As shown, the solid arrow in the figure is the running route from area B to area A, and the dotted arrow is the running route from area A to area B.

[0011] According to the direction indicated by the solid arrow, the train departs from track a of area B, passes through section C of track, enters track a of area A or enters track b of area A through crossover line I; the train departs from track B of area B Exit on road b, pass crossover line II and section C, and enter area A-unit road a or cross-over line I into area A-unit road b.

[0012] According to the direction indicated by the dotted arrow, the train departs from track a in area A, passes crossover line II and section D, and enters track b in area B or crossover line I enters track a in area B; Drive out from the area A track b, pass through the track D section, enter the area B track b o...

Abstract

The invention discloses a method for transporting through double crossovers in a narrow construction space. Materials are transported between a region A and a region B of the narrow construction space through a track which is provided with a crossover I and a crossover II on a station track a and a station track b which extend in parallel; and motor vehicles on the double crossovers are arranged to run in the following way: the motor vehicles pass through the crossover I and the crossover II at a crossing position to realize the conversion of transportation lines on the station track a and the station track b; and the motor vehicles run in one way on a segment C and a segment D between the double crossovers. The method has the advantages that: (1) smooth goods transportation is realized, and the problem of traffic jam of the motor vehicles is solved; and (2) a plurality of rains can be contained according to the lengths of the segment C and the segment D, the assembly and disassembly work of four working stations is ensured to the maximum extent, and the transportation efficiency in the narrow construction space is increased.

Description

technical field [0001] The invention relates to a tunnel construction method, in particular to the technical field of shield machine tunnel construction. Background technique [0002] While tunneling, the shield machine completes slag discharge, segment transportation and support. Its internal space is narrow, especially when the diameter of the shield body is only 4 to 5 meters, and the slag is discharged by locomotive and rolling stock, these tasks must be completed at the same time, and the design requirements for its internal track and its turnout are even higher. The general shield machine is transported on the internal track by using a single-track line near its head. This head is transported in a single line, but the tail is a two-line transport mode, which does not maximize its transport potential, so it needs to be improved. This method corresponds to the narrow space double-crossover transportation mode, and this method can give full play to the transportation po...
