Construction construction method null of collapsible culvert block and collapsible culvert

摘要

PROBLEM TO BE SOLVED: To provide an assembly type culvert block and a construction method therefor capable of obtaining the same strength as a single structure by energizing a pressing force on a contact face where assembly type culvert blocks dividedly manufactured are connected and reducing cost required from the manufacture to the construction. ;SOLUTION: An axial force P1 is generated in a treaded part for connection As of an anchor bolt AN, and a pressing force P2 is applied on a contact face connected through an adhesion force for concrete of the anchor bolt AN for energization by tightening a connection device 200 having an axial line error absorbing means provided among a bottom block 50, right and left side wall blocks 60, and a top block 70 which are dividedly manufactured and integrated. These assembly type culvert blocks BX are united and are provided continuously to construct the assembly type culvert block.;COPYRIGHT: (C)2000,JPO
