GUIDE DEVICE FOR BEING USED TO DRIVE CORE MATERIAL FOR DIAGONAL EARTH RETAINING WALL, AND METHOD FOR DRIVING CORE MATERIAL FOR DIAGONAL EARTH RETAINING WALL

摘要

PROBLEM TO BE SOLVED: To accurately drive a plurality of core materials, which constitute a diagonal earth retaining wall, in such a manner that they are linearly arranged and that each of them makes a predetermined angle of inclination, even when a pile driver cannot be installed on a lot on the outside of an excavation area. ! SOLUTION: A guide device 10 comprises a plurality of guide materials 16 and 20 that are supported by a pile 12 and or a pile 14 and that are arranged in such a manner as to be elongated in parallel with each other in a direction in which soldier beams 1 of a diagonal earth retaining wall are lined. The plurality of guide materials 16 and 20 are arranged in such a manner that a core material 1 tilted to the outside of an excavation area 2 abuts on a first position on the guide material 20 and a second position on the guide material 16 on the downside with respect to the first position and on the side of the excavation area 2. !
