Embodiment Construction

[0023] Aiming at the deficiencies of the prior art, the invention proposes a superplastic stone blocking net. It adopts a rotatable steel column and base mechanism, and cooperates with superplastic anchor rods to effectively share the impact force of the steel wire mesh. It will not break under load, and at the same time, it is convenient for the replacement of steel wire mesh and anchor rod.

[0024] Please combine Figure 1-Figure 8 According to the present invention, the superplastic stone barrier includes a steel wire mesh 1, a steel column 2, a steel column base 3, an anchor rod 4, and an anchor rod base 5. Wherein, the steel column base 3 and the anchor base 5 correspond to each other (that is, one steel column base 3 corresponds to one anchor base 5, but the specific installation positions of the two can be adjusted according to actual conditions) fixed on the foundation superior. The first end of the steel column 2 is rotatably connected to the steel column base 3 ....

Abstract

The invention discloses a superplastic stone blocking net. The superplastic stone blocking net comprises steel wire nets, steel columns, steel column bases, anchor rods and anchor rod bases; the steel column bases and the anchor rod bases are fixed on a foundation; a first end of every steel column is connected with the corresponding steel column base in a rotatable mode; the anchor rods are formed by superplastic materials; a first end of every anchor rod is connected with the corresponding steel column in a rotatable mode; a second end of every anchor rod is connected with the corresponding anchor rod base in a rotatable mode; the steel wire nets are formed by superplastic materials; the bilateral sides of every steel wire net are connected with the two adjacent steel columns. According to the superplastic stone blocking net, a decompressor or decompression ring device of a passive side slope protection system is omitted, the force transfer path of the stone blocking net is changed through the design of rotatable structures of the steel columns and the steel column bases, the anchor rods and the steel columns and the anchor rods and the anchor rod bases, and accordingly concentrated loads are effectively dispersed into different stress units and accordingly the cracking of the steel wire nets under the large load impact is effectively prevented and the protection effect is greatly improved.

Description

technical field [0001] The invention relates to a slope protection system in the technical field of road safety facilities, in particular to a superplastic stone blocking net. Background technique [0002] Falling rocks and flying objects falling from high altitude in mountainous areas or blasting flying rocks produced by quarries pose a great threat to the safety of vehicles and pedestrians passing on mountain roads or bridges, and may cause damage to structures such as roadbeds or bridges. Therefore, flexible protection systems such as prestressed steel wire mesh are often used in engineering to protect rockfalls, rolling stones and shallow collapses on rocky slopes caused by weathering, rain or vibration. [0003] The existing passive protection is mainly in the form of metal mesh and anchor rod (anchor rope). When the falling rocks and rolling stones caused by vibrations collapse at a high speed, a large impact load will be formed on the passive protection net, which wil...
