Description
Technical field
The utility model relates to high slope zone of fracture active defense construction technology, specifically a kind of high slope zone of fracture active protecting net.
Background technology
Under the complex geological conditions such as severely-weathered tuff, mine tailings accumulation area, zone of fracture, need to protect side slope, reinforce, prevent loose falling rocks from causing potential safety hazard.In work progress, the means such as normal employing artificial removing, bolting support, demolition blasting, protective screening protection.Artificial removing is wasted time and energy, and danger is higher, poor effect.Bolting support cost is higher, has destruction to vegetation.Demolition blasting is for boulder, boulder, and effect is better, but can cause secondary loose falling rocks.Adopt protective screening protection resultant effect better, but at the bottom of its structural strength, there is the technical barriers such as anchoring setting, drawknot be fixing.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of and adopts high slope zone of fracture active protecting net that is embedded, pit type, object be for being in zone of fracture, the high slope zone of fracture in the serious district of mine tailings accumulation body provides active defense construction technology, be applicable to the intensive fragmentation of joints development, have the high slope multi level slope zone of fracture active defense at the position of collapse rock-fall to construct.
The utility model is by the following technical programs: a kind of high slope zone of fracture active protecting net, comprises the reinforcing body that is uniformly distributed and sinks in side slope and is anchored at the anchor pole of the outer end in side slope with annulus through reinforcing body; The annulus of described anchor pole one end is fixedly connected with and laterally strengthens rope and longitudinally strengthen rope; Laterally strengthen rope described and longitudinally strengthen each joining of rope is provided with an anchor pole, laterally strengthening rope and longitudinally strengthen rope intersecting the Double-protection grid protection marker space that is partitioned into being coated with band reinforcing band; Four limits of described Double-protection grid are fixed on by stitching rope laterally to be strengthened, on rope or longitudinal reinforcement rope, being interfixed between the reinforcing band of each adjacent double-layers protective grille by s shape colligation button.
It is further: described reinforcing body is the trapezoidal reinforcing body of upper tail band pit, and trapezoidal reinforcing body is gone to the bottom and entered in side slope, and the annulus of described anchor pole one end is positioned at trapezoidal reinforcing body upper base pit.
Trapezoidal reinforcing body is gone to the bottom to enter in side slope and is not less than 200mm, and trapezoidal reinforcing body adopts high-early (strength) cement pea gravel concreten, and trapezoid cross section size upper base is 200mm, goes to the bottom as 300mm, height are not less than 200mm.
Described Double-protection grid is Double-level Reticulated, and inner layer net is the close order little mesh S0/2.2/50 type grid being close to side slope surface, and outer layer net is the D0/08/300 shaped steel netting of larger mesh.
The reinforcing band bandwidth of described Double-protection grid surrounding is 100mm, the reinforcing band overlapped overlap joint 100mm of adjacent double-layers protective grille.
Described anchor pole adopts φ 16HPB300 reinforcing bar, and inclination angle is 15-25 degree (this inclination angle and side slope angle have no relations), and during anchoring, boring aperture 70mm, bore the dark 50mm of empty depth ratio design load, slip casting intensity is not less than C30.
The utility model adopts the trapezoidal reinforcing body of band pit to improve anchoring effect, protection node; double-deck Double-protection grid with reinforcing band ensures the protection effect of protective screening and improves the intensity of protective screening, buckles colligation fixedly avoid the formation of protection white space between each Double-protection grid reinforcing band by the colligation of s shape.
