Abstract
The invention discloses a repairable flexible passive protection system product which comprises an upper support rope and a lower support rope. A plurality of draw ropes are longitudinally and transversely intertwined between the upper support rope and the lower support rope, a protective net is hung between the upper support rope and the lower support rope in a laid manner, the top of the protective net is supported on underground bed rock via steel columns to form an opening, the bottom of the protective net is fixed onto the underground bed rock via threaded steel anchor rods, the tops of the steel columns are connected with the underground bed rock by draw anchor ropes, pressure reducing plates are arranged on the upper support rope, the lower support rope and the draw anchor ropes, a plurality of through holes are formed in each pressure reducing plate along the length direction of the pressure reducing plate, and the upper support rope, the lower support rope and the draw anchor ropes are penetratingly connected onto the pressure reducing plates by the through holes. The repairable flexible passive protection system product has the advantages that the repairable flexible passive protection system device is simple in structure and reasonable in design, the pressure reducing plates can be reused after being repaired, so that an energy dissipation function can be recovered; the repairable flexible passive protection system product is simple in operation, energy dissipation and pressure reduction effects can be realized, functions of the repairable flexible passive protection system product can be recovered without replacing components after impact of falling objects is intercepted by a protection system, and accordingly the service life of the protection system can be prolonged.
Description
Technical field
The invention belongs to side slope protection technical field, particularly relate to the flexible passive protection system product of a kind of repair type.
Background technology
At present, when side slope protection, in order to offset the impact force of falling object, pressure-reducing ring need to be installed on protective screening, the shortcoming of its existence is: after pressure-reducing ring energy dissipating, can not reuse, guard system is after completing the impact of interception falling object, often need to change component ability restore funcitons, application life is short.How to overcome this technical problem and become this those skilled in the art's problem demanding prompt solution.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the invention provides the flexible passive protection system product of a kind of repair type, not only there is energy dissipating effect of easing stress, and complete after the impact of interception falling object at guard system, do not need to change component and get final product restore funcitons, can solve the problem that above-mentioned prior art exists completely.
To achieve these goals, the technical solution used in the present invention is: the flexible passive protection system product of repair type, comprise upper support rope and lower support rope, upper, between lower support rope, be intertwined with in length and breadth some stay cords, and paving is hung protective screening, on protective screening top, by steel column, be supported on ground base rock and form opening, bottom is fixed on ground base rock by twisted steel anchor rod, steel column top is by drawing anchor line to be connected with ground base rock, upper, lower support rope and draw decompression plate is set on anchor line, on described decompression plate, offer along its length some through holes, on, lower support rope and draw anchor line by through hole be connected to decompression plate on.
Further, there is rounding at described through hole edge.
Further, described through hole has two rows, and through hole is equidistantly evenly arranged, wire rope alternatively up and down be connected in through hole, form wavy.
As preferably, described decompression thickness of slab 16mm, interval 120mm between through hole.
As preferably, described protective screening is multiple twin hexagon net, even if also can there is not situation about destroying continuously when single mesh destroys during use.
Compared with prior art, this beneficial effect of the invention is: simple in structure, reasonable in design, decompression plate can reuse after repairing, dissipating functions can be restored, and simple to operate, not only there is energy dissipating effect of easing stress, and complete after the impact of interception falling object at guard system, do not need to change component and get final product restore funcitons, thereby increase the guard system life-span.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the connection diagram of drawing anchor line and decompression plate;
Fig. 3 is the local structural graph of multiple twin hexagon net.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Referring to Fig. 1 to Fig. 3, the flexible passive protection system product of repair type, comprise upper support rope 4 and lower support rope 5, upper, lower support rope 4, between 5, be intertwined with in length and breadth some stay cords, and paving is hung multiple twin hexagon net 6, on multiple twin hexagon net 6 tops, by steel column 7, be supported on ground base rock and form opening, bottom is fixed on ground base rock by twisted steel anchor rod, steel column 7 tops are by drawing anchor line 8 to be connected with ground base rock, upper, lower support rope 4, 5 and draw decompression plate 1 is set on anchor line 8, on described decompression plate 1, offer along its length two exhausting holes 2, through hole 2 is equidistantly evenly arranged, on, lower support rope 4, 5 form wavy with the through hole 2 that passes that draws anchor line 8 to distinguish alternatively up and down formulas.
There is rounding at described through hole 2 edges, avoid upper and lower supporting rope 4,5, draw anchor line 8 and through hole 2 edge excessive frictions to cause wearing and tearing.
The thick 16mm of described decompression plate 1, interval 120mm between through hole 2.
In order to strengthen protection effect, can also hang ring network 9 the outer paving of multiple twin hexagon net 6.
When interception falling object, utilize upper and lower supporting rope 4,5, draw the friction between anchor line 8 and decompression plate 1 to reach energy dissipating effect of easing stress.Decompression plate 1 runs into pulling force and promotes, when need to promote guard system energy level, can by upper and lower supporting rope 4,5 and to draw anchor line 8 to re-start interspersed, through more through hole 2 on decompression plate 1, recycling; And replaceable, simple to operate, solved pressure-reducing ring can only energy dissipating can not reusable problem.At guard system, complete after the impact of interception falling object, not needing to change component is restorable system function, thereby increases the guard system life-span.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
