CONSTRUCTION METHOD FOR POROUS PIPELINE FOR C.C.BOX

摘要

PROBLEM TO BE SOLVED: To provide a construction method for a porous pipeline for a C.C.Box for a porous pipeline which becomes an underground buried wire combined groove. SOLUTION: In a porous pipeline for concrete precast C.C. Box used in a underground buried wire combined groove works, designated digging is performed and a precast foundation plate is laid on a foundation crushed stone which is subjected to leveling of ground and rolling. A porous pipe block groups 1' formed by assembling required number of arrays porous pipe blocks 1 and integrating the same by a suspension jig 6 special for seveal blocks is lifted by a heavy machine and installed, and subsequently the jig special for several blocks is removed to perform designated back filling.
