Abstract

The invention discloses a passive protective net which is high in flexibility and interception strength, is convenient to install and has a warning function and an installation method of the passive protective net. The passive protective net comprises a steel wire rope net, steel columns used for fixing the steel wire rope net, an upper support rope, a lower support rope, a pulling-up anchor rope and a warning assembly. The bottoms of the steel columns are fixedly installed on a base through connection screw rods. The steel wire rope net and the steel columns are fixedly connected together through the upper support rope and the lower support rope. The top ends of the steel columns are pulled tightly and fixed through the pulling-up anchor rope. The warning assembly comprises tension sensors, control devices, warning lights and buzzers. The tension sensors are arranged on the steel wire rope net or the upper support rope or the pulling-up anchor rope. The control devices, the warning lights and the buzzers are arranged at the top ends of the steel columns. The passive protective net is high in flexibility and interception strength, and a modularized installation mode is adopted, so that the construction period is shortened, and the construction cost is reduced. Workers can find risks conveniently in time through the warning assembly so that the protective net can be checked and maintained accurately in time, and the safety protection performance of the protective net is improved.

Description

technical field [0001] The invention relates to the technical field of slope protection, in particular to a passive protection net with a warning function and an installation method thereof. Background technique [0002] The passive protective net is a whole composed of steel columns and steel wire rope nets, which forms a surface protection for the protected area, thereby preventing the collapse of rocky soil from falling and playing the role of slope protection. Compared with rigid interception and masonry retaining walls, the flexibility and interception strength of passive protective nets are better for absorbing and dispersing the impact kinetic energy of falling rocks. Flying rocks, avalanches, and mudslides are intercepted outside the building facilities to avoid damage to the building facilities caused by disasters. After the existing passive protective net is impacted and damaged, it is difficult to find it in time, which is not conducive to timely repair and maint...
