TIMBERING MEMBER, AND EARTH RETAINING METHOD FOR EXCAVATED PIT USING TIMBERING MEMBER

摘要

PROBLEM TO BE SOLVED: To perform earth retaining work for an excavated pit without a worker entering the excavated pit. SOLUTION: The timbering members 1 formed in an approximately H-shaped cross section comprising a pair of soldier piles 2 with the lower end parts formed in acute-angled shape and a strut 3 disposed between the soldier piles 2, and disposed at set spaces with the flanges facing each other, are driven and erected in the excavated pit P at the set spaces in the lengthwise direction. A panel 6 is dropped in the soldier piles 2 on the same side of the adjacent timbering members 1 over the height of the upper end excavated pit P of the soldier piles 2 so that the respective front and rear edge parts are positioned in spaces formed by a pair of flanges and webs of the soldier piles 2.
