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 with 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 present invention involves the field of tunnel construction, and specially involves a shield -sliding boots curve to push the construction method. Background technique [0002] During the construction of rail transit, due to the construction period, construction site and geology, the shield cannot set up a large starting well. In order to meet the needs of rail transit construction, it is often used in the hard lottery in the long shield range to use mines.Construction of law to shorten the shield machine's excessive rock time, and at the same time, the shield machine is fully maintained during the process of the shield machine, which enables the two major advantages of the flexibility construction of hard rock mines and long -distance economic shield structure.The construction plan will get more and more applications in the rail construction. [0003] How the shield machine is pushing through the cave in the mining law tunnel section is the focus and d...
