Title:
アーチング効果を利用した補強型自立式土留構造体及びそれを利用した地中掘削施工方法
Document Type and Number:
Japanese Patent JP5501478
Kind Code:
B2
Abstract:
In a reinforced self-supported retaining wall structure using an arching effect, a soldier pile integrally formed with a soldier pile insertion portion in a vertical direction in a flange at one end of the soldier pile in which a lagging is inserted is installed at a width B to be perpendicular to the ground. A sheet panel protruding portion is inserted in and connected to the soldier pile insertion portion. A sheet panel protruding portion is serially inserted in a sheet panel insertion portion. A compression support plate protruding portion is inserted in and coupled to the sheet panel insertion portion. A relationship between a length L of a group of serial sheet panels and the width B between two groups of serial sheet panels is 0.5¤L/B¤3.0 in a range of an internal friction angle of earth ¦=10¼34° and a range of an adhesive power C=0.0¼5.0 ton/m 2 so that a back earth pressure is not applied to the front lagging due to the arching effect.
