Rock Shed Tunnel Structure as Retaining Wall and Contructing Method for Such Rock Shed Tunnel Structure

摘要

As the construction of the present invention provides piam ( ) part of the sloping tunnel to cut the slope, slope nor to install a retaining wall for slope protection after a cut, cut separately, and to cause the walls of the tunnel piam parallel to the retaining wall of the functions of the multi-layer construction of a more efficient way, minimizing the surface to be cut by over a piam tunnel excavated soil volume reduction as well as to plan, piam tunnel which can improve the stability of the passage piam tunnel, to a piam tunnel structure and the construction method. ; In the present invention, after forming the cut surface, the lower plate 11 and the cross-sectional structure consisting of an inner wall ja 12 (10), the lower plate 11 is the inner wall toward the outer side ( 12) facing a cut slope, installation phases of ja sectional structure (10) disposed on the surface cutout; Soil pressure such that the slope of the cut cross-section by the support ja structure 10, the inner wall 12 through the side of the cut surface to the fixing in the anchorage 101 and the inner wall of the outer end of the anchorage 101 sikimyeo fixing to 12, with the back of the inner wall 12 and the rear fixing backfill step of anchorage to the back surface to the cut slope backfill; And an upper plate 14 and the outer wall 13 by the angled section assembly installation structure 15 consisting of the integrally ja sectional structure 10 comprises a tunnel structure manufacturing step of manufacturing a piam tunnel constructions (1) piam tunnel construction method, characterized in that there is provided.
