Split starting supporting device applied to tiny starting well and starting construction method

Abstract

The invention discloses a split starting supporting device applied to a tiny starting well and a starting construction method. The problems that construction is difficult and the work efficiency is low of a tiny starting well in the prior art are solved. The split starting supporting device comprises a main machine, a segment erector and a spiral conveyer, a first rail and a second rail are arranged at the bottom of the starting well, the first rail is provided with a segment transferring platform or a slag trolley, one end of the segment transferring platform is connected with a second winding engine arranged in the main machine, and the other end of the segment transferring platform is connected with a first winding engine arranged on the outer part of the starting well; and the second rail is provided with a handling platform, a slag discharge box body is arranged at a slag discharge opening of the spiral conveyer, and the slag discharge box body is connected with the handling platform. According to the split starting supporting device, the segment transferring platform is matched with the first winding engine and the second winding engine to complete 90 degree rotation and transportation of segments, the transportation time and the rotation time of the segments are reduced, and the work efficiency and the transportation flexibility are improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a split starting supporting device and a starting construction method applied to a very small starting shaft. Background technique [0002] In order to reduce the impact of tunnel construction on urban traffic, some tunnel routes will limit the size of the launch shaft during planning, and even in some special areas, the tunnel launch shaft will be limited to a very small size launch shaft, which will increase the difficulty of construction. When the size of the starting shaft of the tunnel is extremely small, after the main engine goes down the shaft, the remaining space of the roadheader is not enough to accommodate a whole section of the supporting trailer to go down the shaft, so the segment conveying device, segment lifting device and post-supporting muck conveying device cannot down the well. Since the segment conveying device and the segment hoisting device ca...
