A kind of active protecting net adopting ring network
Technical field
The utility model relates to side slope flexible guard technology field, is specially a kind of active protecting net adopting ring network.
Background technology
Active protecting net utilizes high strength wire rope flexible net as main composition part, and be aided with the accessory such as anchor pole, supporting rope, in order to the Flexible Safety guard system of harm such as covering, fastening domatic mode punishes domatic eboulement, tumble, be widely used in the engineering fields such as domestic water power, highway, railway, mine, municipal administration at present.
The advantage of active protecting net flexible characteristic is first to make active protecting net system evenly transmit concentration of local load to give full play to the protective capacities of whole system to surrounding, i.e. local stand under load, mass action, makes system can bear larger load and reduces the anchored force requirement of single anchor rod; Secondly, the opening of active protecting net system makes underground water freely to drain, and avoids the slope instability problem caused due to the rising of groundwater pressure; Active protecting net system is to slope pattern feature without particular/special requirement again, does not destroy and changes domatic original landform shape and vegetation growth condition, gives and implements the condition that artificial slope greening remains necessity, engineering and environment are fully merged.
Active protecting net common at present comprises wire rope anchor, supporting rope, iron wire grid and rhombus net, iron wire grid is laid under rhombus net, supporting rope is connected with wire rope anchor, rhombus net is laid in supporting rope, rhombus net is connected by sewing up to restrict to sew up with supporting rope, by supporting rope, stretch-draw is carried out to improve by the stability of the domatic mantle rock body of protection to rhombus net, but because original supporting rope and rhombus net mesh are square structure, make supporting rope can not play good stretch-draw effect to rhombus net, and rhombus net retractility is poor, application life is shorter.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of active protecting net adopting ring network, has telescopicing performance good, and anti-bursting power is strong, the features such as long service life, and technical scheme is as follows:
Adopt an active protecting net for ring network, comprise cross binding rope, longitudinal bracing rope and ring network; Many cross binding ropes and many longitudinal bracing rope cross arrangement form rectangular grid, and the crosspoint place of cross binding rope and longitudinal bracing rope is fixedly connected with prestressed anchor; Ring network four limit is fixed in each rectangular grid by sewing up rope tensioning.
Further, also comprise multiple twin hexagon net, multiple twin hexagon net is fixed under described ring network.
Further, described ring network is also fixedly connected with local anchor pole.
Further, described ring network is winding-type ring network or coil-shaped ring network.
Further, described ring network four limit is provided with tensioned lines, and the end of described stitching rope is fixedly connected with tensioned lines by wire clips.
Further, described cross binding rope is fixedly connected with prestressed anchor by wire clips with the end of longitudinal bracing rope.
Further, the net ring diameter of described ring network is 80mm ~ 500mm.
The beneficial effects of the utility model are, the utility model have employed ring network, because its cover contact can arbitrarily movement within the scope of annulus, and all linked with one another, impact force is easily decomposed, and therefore its retractility is very good, elastic deformation absorbs more multi-energy, anti-bursting power is strong, can significant prolongation active network application life, and adds safety.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.As shown in Figure 1, a kind of active protecting net adopting ring network, mainly comprises cross binding rope 6, longitudinal bracing rope 7 and ring network 2.
Many cross binding ropes 6 and many longitudinal bracing rope 7 cross arrangement form rectangular grid, the crosspoint place of cross binding rope 6 and longitudinal bracing rope 7 is fixedly connected with prestressed anchor 4, and cross binding rope 6 is fixedly connected with prestressed anchor 4 by wire clips with the end of longitudinal bracing rope 7.
Ring network 2 four limit is fixed in each rectangular grid by sewing up rope 1 tensioning, and ring network 2 four limit is provided with tensioned lines 9, and the end of described stitching rope 1 is fixedly connected with tensioned lines 9 by wire clips.Ring network 2 is also fixedly connected with local anchor pole 5, passive net and domatic 8 can be made better to fix, protect more firm.Also be fixed with multiple twin hexagon net 3 under ring network 2, be used for stoping the slump of small size sillar.
During installation, first slip casting also inserts prestressed anchor 4 or rope bolt, then installs cross binding rope 6 and longitudinal bracing rope 7, and stretch-draw tight rear two ends wire clips exposes ring set with prestressed anchor 4 and is fixedly connected with.Then spread from the top down along domatic 8 and hang multiple twin hexagon net 3, lay ring network 2 from the top down again and sew up, often open ring network 2 and all carry out stitching and pre-stretch-draw with stitching rope 1 and surrounding supporting rope, sew up rope 1 two ends and be respectively fixed connection with two wire clips and tensioned lines 9.Scheme of installation as shown in Figure 2.
As preferably, the ring network 2 of use is winding-type ring network, and net ring diameter is 80mm ~ 500mm; Ring network 2 is also feasible selects coil-shaped ring network.
