CONCRETE PLACING-JOINT STRUCTURE AND CONCRETE PLACING-JOINT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a concrete placing-joint structure and a concrete placing-joint method, in which an existing concrete section and a new concrete section are unified surely and the sectional performances of the existing concrete section and the new concrete section can be improved.;SOLUTION: In the concrete placing-joint structure, fillers X are interposed among the existing concrete section 1 and the new concrete sections 2 formed to the side and lower section of the existing concrete section 1 respectively. Injection pipes 3, which are piped along the side faces and base of the existing concrete section 1 and to which a plurality of holes are formed, are interposed among the existing concrete section 1 and the new concrete sections 2, and the fillers X are made to flow in the injection pipes 3. Confirming pipes 8 disposed in upright along the side faces of the existing concrete section 1 from the lower ends of the existing concrete section 1 are interposed among the side sections of the existing concrete section 1 and the new concrete sections 2.;COPYRIGHT: (C)2005,JPO&NCIPI
