PROBLEM TO BE SOLVED: To provide a construction method for protection of a slope surface by which collapse of a slope frame hardly progresses to collapse of the adjacent slope frame, while maintaining the structure that either one of longitudinal or cross beams intersecting with each other is missing. SOLUTION: A plurality of slope frames 20 are structured on the slope surface substantially in parallel to be apart from one another. A cable body 30 is inserted into a through hole 21 formed in the slope frame 20 and a tension force is applied. The cable body 30 is arranged in a substantially straight line. Two split bolts 33 having tapered male screws 33b, respectively, are arranged on both sides of the through hole 21. The split bolts 33 are fixed to the cable body 30 by fastening nuts 32 to the tapered male screws 33b, respectively, and the split bolts 33 are brought into contact with both sides of the slope frame 20 under pressure by the nuts 32 to connect the cable body 30 and the slope frame 20. When the cable body 30 is loosened after construction works finish, the split bolts 33 are loosened off the cable body 30. Then, after the tension force is re-applied to the cable body, the cable body 30 and the slope frame 20 are connected with each other by the split bolts 33. COPYRIGHT: (C)2004,JPO
