Title:
SPRAY SLOPE FRAME CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JP2023158265
Kind Code:
A
Abstract:
To provide a spray slope frame construction method which contributes to long life of a slope frame.SOLUTION: A spray slope frame construction method which does not use a frame mold constructs a slope frame 5 by spraying cement containing material 4 to a long reinforcing-bar substitute material 2 and an assembly frame 3 which holds the reinforcing-bar substitute material 2. The reinforcing-bar substitute material 2 is constituted by integrating a plurality of fiber bundles of fiber-reinforced plastic. The reinforcing-bar substitute material 2 contains the fiber bundles which are crossed in a braid-like manner. Regarding the plurality of integrated fiber bundles, the restraint of the fiber bundles with each other is partially relaxed, and the reinforcing-bar substitute material 2 is deformed so as to correspond to the irregularity of a slope N.SELECTED DRAWING: Figure 1
