ROCK SHED BY USING CORRUGATED STEEL PLATE AND GEOTEXTILE AND THE CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: A rock shed tunnel using corrugated steel plate and geotextile and a construction method thereof are provided to reduce the construction period by applying pocket-type banking method using geotextile. CONSTITUTION: A rock shed tunnel(1) comprises a corrugated steel plate structure(10), a concrete back(20), a base banking part(30), and a buffer material(40). The corrugated steel plate structure is installed on a road. The concrete back is filled between the corrugated steel plate structure and the road surface. The base banking part is formed from the top of the base banking part to the top of the corrugated steel plate structure. The buffer material is formed to the designed height from the upper end of the base banking part and the corrugated steel plate structure, having a declined surface.
