METHOD FOR CONSTRUCTION AND EXECUTION OF CONCRETE RETAINING WALL BY MEANS OF PRECAST CONCRETE MEMBER

摘要

PROBLEM TO BE SOLVED: To enable the realization of a reduction in cost by allowing the standardized product of a precast concrete retaining wall to be mass-produced in a factory in advance and permit the term of work to be shortened by bringing efficiency to site construction in relation to a method for construction and execution of an earth retaining wall for a sloping ground. SOLUTION: The main body 3 of the precast concrete retaining wall having a base 1 and a vertical wall 2 is produced in the factory in advance. Not only a base extending panel 5 added to the end of the base 1 of the main body 3 but also a vertical-wall extending panel 7 added to the upper end of the vertical wall 2 is produced for preparation as a precast concrete member in the factory. Either of the extending panels 5 and 7 is selected according to the circumstance of each job site and added for use to each of the ends of the main body 3 by a coupling means.
