JOINT WATER LEAKAGE PREVENTING STRUCTURE AND CONSTRUCTION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To prevent a water leakage from a joint of a pair of irrigation canal constitutive members continuously provided to constitute an irrigation canal even if the irrigation canal constitutive members make mutually different movements to cause a relatively large displacement. SOLUTION: This water leakage preventing structure 100 includes: the pair of irrigation canal constitutive members 10 continuously provided to constitute the irrigation canal; a backing mortar layer 20 provided to cover the joint 11 of the pair of irrigation canal constitutive members 10 from the inside; a waterproof layer 30 provided on the backing mortar layer 20 to cover corresponding to the joint 11 of the pair of irrigation canal constitutive members 10; and a protective mortar layer 40 laminated on the backing mortar layer 20 to embed the waterproof layer 30. The waterproof layer 30 includes extensible parts 31-34 extensible in the continuously provided direction of the pair of irrigation canal constitutive members 10. COPYRIGHT: (C)2011,JPO&INPIT
