Description
Technical field
The present invention relates to a kind of energy-dissipating structure of the anti-collapse rock-fall of canopy cave or bright cave cave top, belongs to road engineering and disaster
Prevention and cure project field.
Background technology
In the road projects such as highway, railway, canopy cave or bright cave appear in collapse rock-fall disaster Yi Fa area often,
For the harm for preventing falling rocks from causing to circuit and people's lives and properties.Particularly in China mountain area, hillside is steep, once occur
Falling rocks disaster, falling rocks are quite huge to the instantaneous impact on canopy cave cave top, therefore, specially treated need to be done to canopy cave cave top, to reach
To impact force of falling stone is reduced, extend rock-fall impact and last the purpose for preventing canopy cave from being smashed by falling rocks.At present, at the top of conventional canopy cave
Safeguard structure is to backfill certain thickness plain fill on cave top, to make backfill reach buffering effect, backfills thickness to which and has
Certain to require, such as highway in China railway systems standard suggestion backfill plain fill bed course is no less than 1.5 meters, the backfill of such thickness
Soil layer, has high requirements to canopy cave foundation bearing capacity tool, can increase construction cost, and for Special zone, its difficulty of construction is big.This
Outward, as back fill course can occur consolidation under its Gravitative Loads, its buffering effect to falling rocks is caused to reduce, which changes difficulty
Greatly.For the purpose for mitigating load and opposing falling rocks at the top of canopy cave, also there are some canopy caves to add polystyrene when top backfills
The material such as Geofoam plate or GSZ, but its implementation cost and difficulty of construction are larger, and be difficult to change.
The content of the invention
It is an object of the invention to provide a kind of light-duty assembled canopy cave cave top energy dissipating bed course safeguard structure, significantly to drop
The deadweight of energy dissipating bed course at the top of low canopy cave, and the impact capacity that energy dissipating bed course resists falling rocks can be effectively ensured, solve existing canopy
Cave cave top backfill cushion weight is big, buffering effect is not good, be difficult the technical problems such as replacing.
The technical scheme that the present invention solves above-mentioned technical problem employing is as follows：
The anti-collapse rock-fall assembled spring energy dissipating bed course safeguard structure in canopy cave cave top, it is characterised in that the light-duty energy dissipating bed course
Structure is assembled by spring energy dissipating block and is formed, and spring energy dissipating block is made up of spring skeleton and rubbery outer cover, and spring skeleton is arranged on rubber
Glue inside the shell, uses attachment spacers and mode connects for screw to form energy dissipating bed course, energy dissipating bed course is fixed on canopy cave between spring energy dissipating block
Top, arranges waterproof layer between bed course and cave top.
The present invention devises a kind of energy dissipating pad for being formed that assembled by spring energy dissipating block and replaces back fill course at the top of canopy cave, fully
The energy dissipating buffer capacity of spring is make use of, and which is combined to form energy dissipating block with rubbery outer cover, easily assembled, significantly reduce
Difficulty of construction and construction cost, with very strong operability；Further, since spring itself has very strong elastic deformability,
Its parallel connection is formed into spring block there is under rock-fall impact load action preferable shock resistance, impact can be effectively increased and gone through
When, reduce impulsive force of the falling rocks to cave top, it is ensured that the normal operation of canopy cave；And due to replacing traditional returning with spring energy dissipating pad
Fill stratum, significantly reduces cave top loading load.Additionally, spring energy dissipating pad is made up of spring block, when energy dissipating bed course local is damaged
When, replacement operation is carried out to spring block simply, maintenance process is easily carried out.Therefore, spring energy dissipating pad has good economy, ring
Protect and Benefits of Disaster Reduction.
Preferably, energy dissipating block spring rate is no less than 103KN/m, spring diameter should be between 10cm-15cm.
Further technical scheme is the assembling of spring energy dissipating block and to assemble them into the mode of energy dissipating bed course as follows：
Spring energy dissipating block is cubic shaped, is made up of spring skeleton and rubbery outer cover, and spring skeleton includes spring, fixation
Framework, retainer plate and series connection steel wire, by spring array in fixed frame, the spring adjoined with fixed frame edge is by solid
Fixed circle is fixed on fixed frame, with steel wire series connection of connecting between spring and spring, spring is formed an overall skeleton；Rubber
Shell includes rubber case and rubber cover plate, and there is connecting hole at the angle of rubber box top four, for the connection between spring energy dissipating block, rubber
Glue case bottom opening, has assembling circular hole in four faces of rubber case bottom, has and rubber bottom portion four in four side end face of rubber cover plate
The corresponding assembling circular hole in individual face lower end, spring skeleton is positioned in rubber case, and rubber case is with rubber cover plate by assembling screw
Connection sealing, forms spring energy dissipating block.
As the effect of rubbery outer cover is to ensure that spring overall stress and can play waterproof action, and rubber should on vertical
With very strong ductility, preferably, the tensile strength of elastomeric material should be between 4.0-12.5MPa, tearing strength should be in 9-
Between 55kN/m, elongation is no less than 100%.
The installation method of spring energy dissipating bed course is as follows：Spring energy dissipating block attachment spacers and connecting screw connection are just formed
Energy dissipating bed course, spring energy dissipating bed course is fixed on canopy cave cave top, i.e., pre-buried on four angle points at the top of canopy cave with being embedded in advance
Preformed hole of the reinforcing bar on four angle points of spring energy dissipating bed course, is fixed on cave top.
The key technology of the present invention is at the top of canopy cave to replace traditional backfill with the light-duty energy dissipating bed course that spring makes
Layer, forms and a kind of is easily installed replacings, deadweight compared with gently and the fabulous canopy cave top protection structure of effect of energy dissipation, it is adaptable to which avalanche falls
The canopy cave building location that stone disaster is easily sent out.
The invention has the beneficial effects as follows：Compared with the back fill course safeguard structure of traditional canopy cave cave top, the structure effect of energy dissipation
Preferably, as spring itself has good shock-absorbing capacity, rushing for falling rocks can effectively be delayed in the presence of rock-fall impact load
Energy is hit, reduces impact force of falling stone, extended rock-fall impact and last.Further, since the structure is assembled by spring energy dissipating block formed, its
Middle spring energy dissipating block can be made by factorial praluction, be transported to construction site and directly installed, it is easy to construct, effectively can reduce
Construction cost.And when spring energy dissipating bed course Local Damaged in use, replacement operation is carried out to which simply, can be in time
Ensure the safe operation of canopy cave.
