Description
Technical field
The present invention relates to civil engineering, more particularly to a kind of steel framework pin-connected panel rockfall is blocked construction, is suitable for
The complicated regional rockfall training works of hardships and dangers.
Background technology
Rockfall Prevention Technique is broadly divided into active defense technology and passive protection technology.Active defense technology is by metal
Flexible net is covered on the slope with potential falling rocks, realizes that one kind that crag is reinforced or constrains in falling rocks near its original position is soft
Property guard technology.Passive protection technology is broadly divided into rigid protection and flexible protection systems.Conventional rigid guard technology includes falling
Stone cistern, bricklaying stone cut off wall block the bank of stone, hangar tunnel or open-cut tunnel structure etc., its advantage is that technically reliable, durability is good, the disadvantage is that cost
Height, construction are more complex.Flexiblesystem includes passive protection net, curtain net, flexible frame etc., has an easy construction, cost is relatively low,
Flexible arrangement, terrain adaptability is good, takes up an area the features such as few, but structural reliability, durability are still to be improved.
Invention content
It blocks construction technical problem to be solved by the invention is to provide a kind of steel framework pin-connected panel rockfall, to have
Effect improves the reliability and durability of safeguard structure, and convenient, environmental suitability of constructing, especially suitable for obstructed water power and nothing
Method uses the regional rockfall training works of complexity hardships and dangers of construction machinery.
The technical solution adopted by the present invention to solve the technical problems is as follows：
The steel framework pin-connected panel rockfall of the present invention is blocked construction, it is characterized in that including：Steel framework barricade, steel
Frame barricade is formed by steel framework unit on-site consolidation, and internal chock stone forms barricade；Energy-dissipating and shock-absorbing drainage blanket, energy dissipating
The covering of damping drainage blanket is layed on the versant surface of steel framework side, forms one of outer buffer layer, and ejectment surface charge for remittance；Slurry
Slabstone stone falling channel is built, is set to after wall at slope foot, both lateral sides meet stoneledge face drop-over with falling rocks slope surface and construction of blocking；Rigidity
Protection network is fixedly installed on the top of barricade.
The energy-dissipating and shock-absorbing drainage blanket is by internal ring spring pipeloop and the solid netted knot of resilient three-dimensional for hollow-core construction
The permeable gauze pad of structure is combined, and ring spring pipeloop is arranged at intervals in permeable gauze pad.
The invention has the advantages that for obstructed water power, the hard and dangerous regional rockfall of the complexity of construction machinery can not be used
Training works provide the gear protection structure that a kind of construction is convenient, structure is reliable, cheap, environmental suitability is strong；It is rigid with tradition
Property, semi-rigid safeguard structure compare, cost is lower, speed of application faster, environmental suitability is more preferable, and drainage is efficient, right
Foundation bearing capacity requires low, flexible arrangement, environment terrain adaptable；Compared with flexible protective structure, reliability, durability
Higher；Construction investment is advantageously reduced, later maintenance cost is saved, there are excellent economic results in society.
Description of the drawings
This specification includes such as next width attached drawing：
Fig. 1 is that steel framework pin-connected panel rockfall of the present invention is blocked the cross-section diagram of construction；
Fig. 2 is the cross-section diagram of energy-dissipating and shock-absorbing drainage blanket；
Component and corresponding label are shown in figure：Steel framework barricade 10, block stone 11, energy-dissipating and shock-absorbing drainage blanket 20, annular
Spring pipeloop 21, permeable gauze pad 22, mortar flag stone stone falling channel 30, filling body 31, rigid protective net 40.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples.
Referring to Fig.1, steel framework pin-connected panel rockfall of the invention construction of blocking includes：Steel framework barricade 10, steel
Frame barricade 10 processed is formed by steel framework unit on-site consolidation, and internal chock stone 11 forms barricade；Energy-dissipating and shock-absorbing drains
Layer 20, the covering of energy-dissipating and shock-absorbing drainage blanket 20 are layed on 10 side versant surface of steel framework barricade, form one of outer buffer layer,
And ejectment surface charge for remittance；Mortar flag stone stone falling channel 30 is set to after wall at slope foot, both lateral sides and falling rocks slope surface and structure of blocking
It makes and meets stoneledge face drop-over drop-over；Rigid protective net 40 is fixedly installed on the top of barricade.
Steel framework barricade 10 is formed by steel framework unit on-site consolidation, barricade steel framework unit by prefabrication simultaneously
Galvanizing by dipping preservative treatment is carried out, production efficiency is high, quality controllable, while artificial carry can be used and assemble, especially suitable for not
Water flowing electricity can not use the regional rockfall training works of complexity hardships and dangers of construction machinery.
With reference to Fig. 2, the energy-dissipating and shock-absorbing drainage blanket 20 is by the internal ring spring pipeloop 21 for hollow-core construction and elasticity three
The permeable gauze pad 22 of dimension space network is combined, and ring spring pipeloop 21 is arranged at intervals in permeable gauze pad 22.It is described
The thickness of permeable gauze pad 24 is 30cm, elasticity modulus 0.05-0.5MPa, porosity of=60%.Energy-dissipating and shock-absorbing drainage blanket 20 is not only
Construct internal water accumulation is discharged rapidly with good buffering energy-absorbing performance, and using its high-voidage, high hydraulic conductivity characteristic, avoids
Water damage significantly improves the durability for construction of blocking.
Referring to Fig.1, rigid protective net 40 intercepts fritter slungshot, increases the effective height of interception of system.Mortar flag stone stone falling channel
30 play draining and collect falling rocks.Compared to conventional flex safeguard structure, maintainable, reliability and durability are more preferable.
Compared to conventional rigid, semi-rigid safeguard structure, cost is lower, easy for construction, flexible arrangement, drainage efficiency higher, and environment is suitable
Answering property is stronger, has significant economic technique superiority.
Referring to Fig.1, the steel framework barricade 10 is in step-like by versant, and energy-dissipating and shock-absorbing drainage blanket 20 is completely laid on steel
10 surface of frame barricade.Backfill stone shape in gap between 30 bottom surface of mortar flag stone stone falling channel and falling rocks slope surface, barricade
At filling body 31.
The above steel framework pin-connected panel rockfall of the present invention that only explains through diagrams is blocked some principles of construction,
Be not intended to by the present invention be confined to shown in and the concrete structure and the scope of application in, therefore every be possible to be utilized
Corresponding modification and equivalent belong to the apllied the scope of the claims of the present invention.
