摘要

PROBLEM TO BE SOLVED: To provide an earth retaining timbering structure capable of stably holding a planar shape of a work space, by widely securing the work space by omitting an angle tie beam, and preventing deformation of a wale even when using no angle tie beam.SOLUTION: An earth retaining timbering structure comprises a plurality of earth retaining walls 10 erected so as to abut on an excavation surface of the ground, a plurality of planar L-shaped corner members 20 arranged in the four-corners of a work space defined by the plurality of earth retaining walls 10, and a plurality of wales 30 joined to the corner members 20 and horizontally extended so as to support the earth retaining walls 10.SELECTED DRAWING: Figure 1
