Problems solved by technology

[0006] The present invention solves the problem that the large shield machine pushes through the tunnel section of the mining method after the second lining has been constructed on the whole curve without assembling the segments, and provides a tunnel-passing construction that pushes up the curve with a large thrust and avoids segment assembly method

Embodiment approach

[0044] The present invention is aimed at shield tunneling through the mine method tunnel that has been lined, and its specific implementation method is as follows:

[0045] Such as figure 1 and figure 2 As shown, two side-by-side steel plates are installed on the concrete guide platform of the mining method tunnel. The steel plates are fixed on the concrete guide platform with embedded self-anchoring bolts, and the uneven position of the bottom of the plate is filled with steel material support pads. The steel plates are installed in sections according to the jacking degree, and are reused; the two steel plates installed side by side are the sliding shoes 1 for the shield machine 6 to travel; butter is applied to the surface of the laid steel sliding shoes 1 .

[0046] The core-pulling method is used to drill the counter force hole 2 in the middle of the slide shoe 1, and two rows are arranged according to the jacking force, and each row has three counter force holes 2, and ...

Abstract

The invention discloses a shielding sliding shoe curvilinear pushing-up hole-passing construction method, which comprises the following construction steps: laying a sliding shoe (1); punching reaction holes (2); anchoring a multi-support leg reaction frame (3) into the reaction holes (2); regulating a shielding machine (6); transporting a segment by a crane; pushing the segment; transporting a second segment by the crane, and meanwhile, arranging a plurality of force transfer steel beams (4); pushing the segment, integrating the segment and the force transfer steel beams (4), transferring out the force transfer steel beams (4) after a jack is contracted, and jacking the jack again to closely attach the second standard shielding segment to the first standard shielding segment. The method generally has the beneficial effects that a good linear control function is realized; the ratio of the weight of the shielding machine to pushing force is relatively greater, and the pushing-up requirement of a large shielding machine is met; the segment splicing amount is minimum, and materials are saved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a construction method for pushing a shield sliding shoe through a hole on a curve. Background technique [0002] In the process of rail transit construction, due to the construction period, construction site and geological reasons, the shield tunnel cannot be equipped with more starting and receiving shafts. In order to shorten the time for the shield machine to pass through the hard rock, at the same time, the shield machine is fully maintained during the process, so that the two advantages of short-distance hard rock mining method flexible construction and long-distance economical shield method construction are effectively combined. Construction schemes will gain more and more applications in track construction. [0003] How to push the shield machine through the tunnel section of the mining method is the focus and difficulty of the above-mentioned construction plan. The cur...
