<P>PROBLEM TO BE SOLVED: To provide a construction method that enables complete repair when an eroded area of a steel sheet pile-type drainage ditch is repaired by reducing costs to the utmost. <P>SOLUTION: Costs of equipment and materials for use can be kept low by eliminating the use of heavy equipment and a large-scale apparatus and improving a fixed-type temporary scaffold to change it to a gondola-type movable scaffold. Subsequently, since workability of preparation of attachment of a stiffening plate of a steel plate is greatly improved by a socket-nut press-in operation from a unilateral surface dispensing with the operation of digging up a backside of a steel sheet pile, costs required for the number of workers and working hours for repair work can be kept low. Revetment capacity is restored because the full adhesion between the stiffening plate of the steel plate and the steel sheet pile enables structural integration. <P>COPYRIGHT: (C)2012,JPO&INPIT |
