The invention discloses a tree-anchored flexible protection system and an inspection and evaluation method thereof, comprising a plurality of anchoring devices and a multi-span protective net; the plurality of the anchoring devices are used to be fixed on trees, between two adjacent trees The protective nets are provided with one span, and each span of protective nets is matched with 4 anchoring devices. The anchoring positions of different spans on the same tree are kept dislocated in height, and the bottoms of trees with smaller diameters are reinforced with supports and concrete platforms. At the same time, an inspection and evaluation method of the tree-anchor flexible protection system is proposed, so as to realize the evaluation of the impact resistance of the tree-anchor flexible protection system, especially the rapid judgment of the anchoring strength of the support rope. The invention is suitable for complex slopes. In the field of rockfall interception protection, the protection effect is good, easy to install and repair, and the state of the detection hoop can be adjusted as the tree grows, which has good protection measures for the tree, and is green and environmentally friendly.
Description
technical field [0001] The invention relates to the field of slope geological disaster protection, in particular to a tree-anchored flexible protection system and an inspection and evaluation method thereof. Background technique [0002] Flexible protection systems have been widely used in the prevention and control of slope geological disasters such as rockfalls, collapses, landslides, and debris flows, and have achieved remarkable results. [0003] In the prior art, the Chinese patent document discloses that the application number is CN201520727261.3, and the name is an improved flexible passive protective net, which consists of a multi-span protective net, and each span of the protective net is fixed on two steel columns by a metal net. There is a shackle fixed on the top plate of the top of the steel column, the bottom of the steel column is hinged on the base of the steel column, and a shackle is fixed on the base of the steel column; the upper support rope is hung from...
