摘要：PURPOSE:To stabilize and protect a face of slope having a low anchor effect, by a method wherein a coil spring and a climp lath are laterally and longitudinally stretchedly placed on a face of slope, and are secured to a ground by passage of a wire rope through the central part of the spring, and concrete is sprayed thereon. CONSTITUTION:A coil spring 1 is stretched so as to form one pitch of the meshes of a climp lath 4, and with this, the spring 1 is laterally and longitudinally placed on a face of slope. A main anchor 2 is secured to a spot, where the springs 1 cross each other at right angles, and a subanchor 3 is secured to an intermediate spot between the main anchors. Both sides of the spring 1 are covered with the climp lath 4, and concrete is sprayed thereon to form a spring frame 5. Main wire ropes 6 are extended through the face of slope from the top thereof to the toe thereof, and are secured to a PC steel rod 7. Further, subwire ropes 8 are extended in the horizontal direction of the face of slope, both ends are secured to the PC steel rod 7, and concrete is sprayed in the spring frame 5 to build slope forms 10.
