Description
Technical field
The invention belongs to tunnel and slope project technical field, especially relating to a kind of resistance buffer for preventing and treating falling rocks.
Background technology
In slope project or the area having crag to distribute, falling rocks is hurted sb.'s feelings or the accident that affects programming frequently has generation, produce to engineering safety and bring very big potential safety hazard, therefore, safeguard procedures need be set in crag region and occur to prevent all kinds of engineering accident caused due to falling rocks.The measure of current existing control falling rocks mainly gabion box, rock-fall protection net, rock-fall proof canopy, barricade adds and blocks stone grid, bellows grid, the wire gauze utilizing trees to arrange and wire lath covering etc., but the slump of zonule or this extremely indivedual Dangerous Rock Body is prevented and treated, above measure not only consumable quantity is large, cause unnecessary economic waste, and once protect improper, large-area falling rocks will be caused to drop or tumble, and safety need to improve.Therefore, even if how to guarantee that sillar drops, be also unlikely to threaten to people's life and property safety, be more and more subject to the great attention of vast construction, unit in charge of construction and government department.
Summary of the invention
Object of the present invention, exactly for overcoming the defect that above-mentioned prior art exists, provides a kind of resistance buffer that can be used for preventing and treating falling rocks.
Object of the present invention can be achieved through the following technical solutions:
A kind of resistance buffer for preventing and treating falling rocks, it comprises flexible steel wire guard, steel loop fastener, umbrella rope, drag parachute sleeve, steel strand, wire, drag parachute and expansion bolt, the two ends of described flexible steel wire guard connect steel strand one end respectively, described drag parachute edge is provided with some steel loop fasteners and their difference Connectable umbrella rope one end, and the umbrella rope other end is connected by steel loop fastener with the corresponding steel strand other end respectively; Described drag parachute is accommodated in drag parachute sleeve, and the wire rope that drag parachute sleeve top is fixed with one end is connected; Flexible steel wire guard is fixed on crag two ends by expansion bolt.
Described flexible steel wire guard is formed primarily of gauze wire cloth, steel strand, loop fasteners, drag parachute, and drag parachute is accommodated in resistance sleeve, and loop fasteners is distributed in guard two ends, for connecting drag parachute.
When crag be disturbed drop time, flexible steel wire guard drops together with Dangerous Rock, drag parachute departs from resistance sleeve immediately and opens, simultaneously, under aerostatic buoyancy and block conduct oneself with dignity acting in conjunction, flexible steel wire guard two ends under tension and be shrunk to bag-shaped, wraps country rock block and is unlikely to drop from guard.
Described flexible steel wire guard covers danger stone surface, makes guard be connected with contiguous rock mass stability or cohere, make it to be unlikely to drop by wire or surrounding injecting glue liquid.
The material of described drag parachute is mainly Polyamide Yarns textile material, fabric intensity is high, tear resistance and good endurance, drag parachute edge is provided with steel loop fastener, make it to be connected with steel strand, the steel strand other end is connected with the steel loop fastener at flexible steel wire guard two ends with distribution, and drag parachute main part is accommodated in resistance sleeve.
Described resistance sleeve main component is aluminium alloys, and its advantage is lightweight, not easily corrosion.Sleeve size with just in time receive drag parachute compression after volume capacity be advisable, sleeve top wire connects, and wire other end is bound to contiguous rock mass stability place.
Described steel strand are divided into two parts, an a part of part as flexible steel wire guard main body, as surrounding and the overall skeleton of tying flexible steel silk screen; Another part is as the umbrella rope of drag parachute, and one end is connected with the steel loop fastener on drag parachute, and the other end is connected with the steel loop fastener on flexible steel wire guard.
Described flexible steel wire guard, expansion bolt, steel loop fastener are made by chromium plating stainless steel.
Compared with prior art, the present invention has the following advantages:
1, make guard be connected with contiguous rock mass stability or cohere by wire or surrounding injecting glue liquid, avoid causing Secondary Disturbance to Dangerous Rock;
2, adopt local compliance steel wire guard, avoid the wasting of resources that large area cover type protective screening brings;
3, drag devices structure is simple, easy for installation;
4, apparatus structure is comparatively light, and it is large that the actual total lifting surface area in bottom and entirety wrap up area, can more safely stop falling fast of Dangerous Rock.

Fig. 2 be the crag of control falling rocks drag devices of the present invention drop drag parachute open after schematic diagram (a);
Fig. 3 be the crag of control falling rocks drag devices of the present invention drop drag parachute open after schematic diagram (b);
Fig. 4 is the flexible steel wire guard detailed maps of control falling rocks drag devices of the present invention;
In figure, 1 is flexible steel wire guard, and 2 is steel loop fastener, and 3 is umbrella rope, and 4 is drag parachute sleeve, and 5 is steel strand, and 6 is wire, and 7 is drag parachute, and 8 is expansion bolt.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
For preventing and treating a drag devices for falling rocks, agent structure as shown in Figure 1,2,3, 4.This device comprises flexible steel wire guard 1, steel loop fastener 2, umbrella rope 3, drag parachute sleeve 4, steel strand 5, wire 6, drag parachute 7 and expansion bolt 8.
In Fig. 1, right stabilizer rock mass, wherein flexible steel wire guard covers on crag rock mass (meaning not shown in the figures) bottom.Guard top is exactly crag rock mass, it is fixed on crag rock mass around guard with fluid sealant.
When device is implemented, flexible steel wire guard is covered on crag rock mass bottom side surface, by wire or around injecting glue liquid guard is connected with crag rock mass or coheres, make it to be unlikely to drop, or be fixed on expansion bolt 8 stone two ends of endangering.
Drag parachute 7 is connected respectively by the steel loop fastener 2 of eight umbrella ropes 5 with flexible steel wire guard 1 two ends, and drag parachute 7 is incorporated among resistance sleeve 4, and sleeve upper end is bound in contiguous rock mass stability by wire 6.
When crag be disturbed drop time, flexible steel wire guard 1 and Dangerous Rock drop in the lump, drag parachute 7 departs from resistance sleeve 4 immediately and opens, simultaneously, under aerostatic buoyancy and block conduct oneself with dignity acting in conjunction, flexible steel wire guard 1 two ends under tension and be shrunk to bag-shaped, wraps Dangerous Rock and is unlikely to drop from guard 1.
Based on this, compared with prior art, the present invention can be more reliable easily for preventing falling rocks from falling or tumbling at a high speed, brings more sound assurance to people life property safety.
