Abstract
The utility model discloses a curtain type protective screen. The curtain type protective screen comprises a protective screen body. The protective screen body comprises an upper supporting rope and a lower supporting rope, a plurality of pull ropes are interweaved between the upper supporting rope and the lower supporting rope vertically and horizontally, and a twisted-pair hexagonal screen is laid and hung. As steel columns are supported on the underground bedrock, an opening is formed in the top end of the protective screen body, the bottom end of the protective screen body is fixed to the underground bedrock through threaded steel anchor stocks, and an annular screen is laid and hung at the position, close to the steel columns, of the top of the twisted-pair hexagonal screen. Galfan cladding layers are arranged on the surfaces of the annular screen and the twisted-pair hexagonal screen. As the steel columns are supported on the underground bedrock, the opening is formed in the top end of the protective screen body, intervals are formed between the protective screen and a mountain so as to restrain the speed of rock falling, the rolling track of the falling rock is guided, the purpose of protection is achieved, secondary rock falling damage is thoroughly avoided, and the protection level is increased greatly. As the twisted-pair hexagonal screen is adopted, even if a single screen hole is damaged, continuous destruction will not occur. The Galfan cladding layers are arranged on the surfaces of the annular screen and the twisted-pair hexagonal screen, so that the corrosion resistance is improved, and the service life is prolonged greatly.
Description
Technical field
The utility model belongs to side slope protection technical field, particularly relates to a kind of curtain formula protective screening.
Background technology
At present, when side slope protection, traditional active protecting net is, by anchor pole, zone of protection man-made division is become to many fritters, employing be " parcel " theory, make initiatively " parcel " falling rocks of protective screening, thereby play the object of protection.This protective screening there will be the phenomenon of " bulge ", makes falling rocks pile up, rest on a certain region, is difficult to safeguard cleaning, forms the harm of secondary falling rocks.What active network adopted is rhombus net and grid, rhombus net adopts cross cramp, and cross cramp antiseptic power is poor, the life-span is short, it is the short slab of systematic protection performance, grid is " simple lay net " because of what adopt, after wherein a certain mesh is thrust, whole grid occurs to destroy continuously and lost efficacy.Tradition protective screening is owing to being subject to falling rocks frontal impact, and its protection energy level is relatively little.The problem that how to overcome this above-mentioned prior art existence becomes this those skilled in the art's problem demanding prompt solution.
Utility model content
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of curtain formula protective screening, reduces frontal impact, and protection energy level promotes greatly, and the situation of destruction continuously can not occur, and can solve the problem that above-mentioned prior art exists completely.
To achieve these goals, the technical solution adopted in the utility model is: curtain formula protective screening, comprise protective screening, and this protective screening comprises upper support rope and lower support rope, is intertwined with in length and breadth some stay cords between upper and lower supporting rope, and paving is hung multiple twin hexagon net.
As preferably, the top of described protective screening and bottom are fixed on ground base rock by twisted steel anchor rod.
As preferably, described protective screening top is supported on ground base rock and is formed opening by steel column, and bottom is fixed on ground base rock by twisted steel anchor rod, and the position paving at multiple twin hexagon net top near steel column is hung ring network.
Further, the hinged pedestal in described steel column bottom is fixed on ground base rock, and top is by drawing anchor line to be connected with ground base rock.
Further, at upper and lower supporting rope with draw decompressor is installed on anchor line.
Further, described upper and lower supporting rope and draw anchor line all to leave free end.
Further, the angle between described steel column and ground base rock is 90 °～110 °.
Further, described ring network is formed by some steel wire latch closure connection, and each steel wire ring is wound around 4 to 9 circles by individual wire and forms.
Further, ring network and multiple twin hexagon net surface are provided with Gao Erfan coating.
Compared with prior art, the beneficial effect of this utility model is:
1. adopt steel column supporting protection net top to form opening, form the speed of gap restriction falling rocks between protective screening and massif, guiding falling rocks tumbles track, reach the object of protection, effectively reduce frontal impact, avoided the harm of secondary falling rocks completely, protection energy level significantly promotes.
2. use multiple twin hexagon net, even if also can there is not the situation of destruction continuously when single mesh destroys.
3. ring network and multiple twin hexagon net surface are provided with Gao Erfan coating, and antiseptic property improves, and significantly increases the service life.
