What are the conventional specifications and construction techniques for rigid passive fencing?
Introduction to Rigid Passive Protective Net
Rigid passive protective net system conventional height is generally 1.8M or 2.5M, rigid protective net column spacing can be appropriately increased (such as 3m a 4m), when the small size of small stone, the upper and lower wire rope may be crushed after deformation Through the increase, so the spacing to maintain the plate, the addition of thin steel plate relative to reduce the spacing of steel columns, the cost of a substantial reduction in the distance between the wire rope to maintain the twisted pair of six steel wire mesh wire mesh set on the one hand is to intercept small particles The same time can also increase the overall performance of the system.Currently domestic steel grille with single twist and twisted two weaving methods, when a single wire break, compared to single-twisted way, twisted grid grid is not Prone to continuous damage, so the new rigid protective net with twisted-pair hexagonal steel mesh, the end of the column set oblique support to prevent the end of the column when the tensile force along the direction of the rope overturned, the end of the steel column with bracing. Support can be used angle steel or channel
Rigid Passive Protective Net Durability principle Steel column, bracing, wire rope, connecting pieces such as hot dip zinc corrosion.
As the wire diameter of the steel wire is smaller, it is easier to lose the protective performance after corrosion. In order to increase its corrosion resistance, the galvanized-5% aluminum-mixed rare earth alloy coating (also known as galvanized) Anticorrosion method of anti-corrosion life than the galvanized high 2 to 3 times the structural durability of the steel mesh compared to the general increase.
The spring type energy dissipator is composed of a sleeve, a rod, a screw and a spring, the rod is fixedly connected with an end face of the sleeve, the rod is connected with the wire rope through the rope card, the spring is placed at the rear end of the screw in the sleeve, It is simple and effective, easy to install, and easy to replace.
Passive protection is made of wire rope net, ring net, (need to intercept small pieces of rock fall when a layer of wire grille), fixed system (anchor, pull rope, base and support rope) decompression ring and steel column four main Part of the composition. Steel column and wire rope connection combination to form a whole, the protection of the area to form surface protection, thus preventing the collapse of rock rock falling, play a slope protection.
Material: Wire rope, support rope and decompression ring Construction: by wire rope net or ring network (need to intercept small pieces of rock when the additional layer of wire grille), fixed system (anchor, anchor rope, base and support rope) , Pressure reducing ring and steel column Four main parts of the product characteristics: the system flexibility and interception strength enough to absorb and disperse the expected impact of rock mass kinetic energy, energy consumption ring design and use of the system to further improve the impact resistance. Rigid intercept and mortar retaining wall compared to change the original construction technology,

Product use: suitable for construction facilities next to the buffer zone of the mountains, the rock collapse, flying stone, avalanche, debris flow intercepted in the construction facilities, to avoid the destruction of the destruction of construction facilities Ring protection system:
Product features: the use of several pieces of steel wire plate formed by the ring and the formation of each other network. Applicable to the construction of facilities next to the buffer zone of the mountains, the rock collapse, flying stone, avalanche, debris flow intercepted in the construction facilities, to avoid the destruction of the construction of disasters. Its role is to intercept rockfall protection energy is generally 150kj - 2000kj
Construction Technology of Rigid Passive Protective Net
Passive fence (including GAR2, GPS2, GER2 and GTC-65A), commonly used in slope collapse, weathered off, slump, slippery or slumping geological disaster reinforcement protection, its obvious feature is the use of system anchor fixed, And according to the different flexible network, respectively, through the support rope and suture tension (wire rope or wire grid) or prestressed anchor (TECCO-65 grille) to achieve the pre-tension on the flexible part of the network, so the entire slope Forming a continuous support, the pre-tensioning operation so that the system as close as possible to the slope, and the formation of inhibition of local rock and soil movement or in the event of local displacement or damage will be bound (stranded) in situ near the prestress, In order to achieve its active protection (reinforcement) function.
Rigid Passive Protective Net The system is designed to ensure that it is as close to the slope as possible in the construction process. The bolt orifice should be cut into the hole (the flexibility of the system arrangement can often be used to set the anchor in the natural low concave position).
