SLOPE FRAME INTERSECTION REINFORCING WORK AND FORMWORK FOR REINFORCING SLOPE FRAME INTERSECTION

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of cracking of mortar or concrete caused by the shortage of strength near the intersection of slope frame and enhance the slip resistance due to excavation at the slope frame intersection and nearby area thereby preventing the lip of the whole slope frame in the nearby area by enhancing slip resistance and by excavating the bottom side of the slope frame at the intersection of the slope frame where the anchors are driven and the nearby bottom surface side of the slope frame for reinforcing by increasing the thickness of mortar or concrete.;SOLUTION: The intersection 1a of a slope frame 1 and the bottom surface side of the nearby area are excavated, the slope frame intersection reinforcing formworks 2, 12 are installed inside the excavated place, a formwork c for slope frame is installed in longitudinal and lateral directions on the upper side of the formworks 2, 12 for reinforcing slope frame intersection, mortar or concrete is sprayed and filled in the formwork c of the surface (a) of the slope and the inside of the formworks 2, 12 for reinforcing the slope frame intersection at the place excavated thereafter, then the slope frame 1 is constructed and an anchor 5 is driven at the intersection 1a of the slope frame 1 after the hardening of the mortar or concrete.;COPYRIGHT: (C)2001,JPO
