SLOPE GREENING CONSTRUCTION METHOD BY CONCRETE SPRAYING SLOPE FRAME BY USE OF SIMPLE SPRAYING PLATE FRAME

摘要

PROBLEM TO BE SOLVED: To provide a slope greening construction method capable of accurately forming a semicylindrical latticelike slope frame which is harmonious with the nature by spraying concrete and obtaining a slope frame having high strength and using a simple spraying plate frame. ;SOLUTION: A simple spraying plate frame 1 in which two bridge type support bars 3 are constituted such that their bridge legs 3a are rotated and pivotally supported in a condition in which two spraying substrate plates 2 having a width L of about 1/4 of a central height H of a latticelike slope frame face each other. This construction method consists of a process in which wire netting 4 is stretched on a slope and is arranged on it through an anchor, a process in which the spraying substrate plates 2 are arranged along fixed reinforcing bars 5, a crossing part of the bridge type support bar 3 and the reinforcing bar 5 is fixed, and the crossing part is fixed on a slope by placing an anchor 7, a process in which concrete is sprayed to cover the whole simple spraying plate frame 1 and a central part of the simple spraying plate frame 1 is raised by placing concrete to form the semicylindrical latticelike slope frame, and a process in which soil dressing is sprayed on the whole surface on the exposed wire netting 4 in the latticelike slope frame.;COPYRIGHT: (C)1999,JPO
