Description
Technical field
The utility model is related to the energy-dissipating structure of a kind of canopy cave or the bright anti-collapse rock-fall in cave cave top, belong to road engineering and
Diaster prevention and control engineering field.
Background technology
In the road projects such as highway, railway, canopy cave or bright cave appear in collapse rock-fall disaster Yi Fa areas often,
For preventing falling rocks from being endangered caused by 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, need to do specially treated to canopy cave cave top, with up to
To impact force of falling stone is reduced, extend rock-fall impact and last the purpose for preventing that canopy cave from being smashed by falling rocks.At present, at the top of common canopy cave
Safeguard structure is to backfill certain thickness plain fill on cave top, and to make backfill reach buffering effect, backfilling thickness to it has
It is certain to require, 1.5 meters are no less than as the suggestion of highway in China railway systems standard backfills plain fill bed course, the backfill of such thickness
Soil layer, has high requirements canopy cave foundation bearing capacity tool, can increase construction cost, big for Special zone, its difficulty of construction.This
Outside, since back fill course can consolidate under its Gravitative Loads, its buffering effect to falling rocks is caused to reduce, it replaces difficulty
Greatly.For the purpose of load and resistance falling rocks at the top of canopy cave is mitigated, also there are some canopy caves to add polystyrene when top backfills
The material such as Geofoam plate or TGXG, but its implementation cost and difficulty of construction are larger, and be not easy to replace.
The content of the invention
The purpose of this utility model is to provide a kind of light-duty assembled canopy cave cave top energy dissipating bed course safeguard structure, with significantly
Degree reduces the dead weight of energy dissipating bed course at the top of canopy cave, and the impact capacity of energy dissipating bed course resistance falling rocks can be effectively ensured, and solves existing
There are the technical problems such as canopy cave cave top backfill cushion weight is big, buffering effect is bad, is not easy to replace.
The technical scheme in the invention for solving the above technical problem 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 formed, and spring energy dissipating block is made of spring skeleton and rubbery outer cover, and spring skeleton is installed on rubber
In glue shell, connected to form energy dissipating bed course with attachment spacers and connecting screw between spring energy dissipating block, energy dissipating bed course is fixed on
Canopy cave cave top, waterproof layer is set between bed course and cave top.
The utility model devises a kind of energy dissipating pad formed that assembled by spring energy dissipating block and replaces back fill course at the top of canopy cave,
The energy dissipating buffer capacity of spring is taken full advantage of, and it is combined to form energy dissipating block with rubbery outer cover, is easily assembled, significant drop
Low difficulty of construction and construction cost, have very strong operability；Further, since spring has very strong elastic deformation energy in itself
Power, its parallel connection is formed spring block has preferable shock resistance under rock-fall impact load action, can be effectively increased punching
Hit and last, reduce impact force of the falling rocks to cave top, ensure the normal operation of canopy cave；And due to replacing tradition with spring energy dissipating pad
Back fill course, significantly reduce cave top loading load.In addition, spring energy dissipating pad is made of spring block, when energy dissipating bed course is locally subject to
It is simple to spring block progress replacement operation during damage, easily carry out maintenance processing.Therefore, spring energy dissipating pad has warp well
Ji, environmental protection and Benefits of Disaster Reduction.
Preferably, energy dissipating block spring rate is no less than 103KN/m, spring diameter should 10cm-15cm it
Between.
Further technical solution 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 of spring skeleton and rubbery outer cover, and spring skeleton includes spring, fixation
Frame, retainer plate and connection steel wire, by spring array in fixed frame, pass through solid with the spring of fixed frame edge adjoining
Fixed circle is fixed on fixed frame, is connected between spring and spring with connection steel wire, and spring is formed an overall skeleton；Rubber
Shell includes rubber case and rubber cover board, 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 board
The corresponding assembling circular hole in a face lower end, spring skeleton is positioned in rubber case, and rubber case is with rubber cover board by assembling screw
Connection sealing, forms spring energy dissipating block.
Since 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 is just formed with attachment spacers and connecting screw connection
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 utility model is that the light-duty energy dissipating bed course made in the very useful spring of canopy cave cave replaces traditional return
Fill stratum, formation is a kind of to be easily installed replacement, dead weight compared with light and fabulous effect of energy dissipation canopy cave top protection structure, suitable for collapsing
The canopy cave building location that slump stone disaster is easily sent out.
The beneficial effects of the utility model are：Compared with the back fill course safeguard structure of traditional canopy cave cave top, the structure energy dissipating
Effect is preferable, since spring has good cushion performance in itself, can effectively delay falling rocks under the action of rock-fall impact load
Impact energy, reduce impact force of falling stone, extend rock-fall impact last.Further, since the structure assembles shape by spring energy dissipating block
Into wherein spring energy dissipating block can be made by being factory produced, and be transported to construction site and directly installed, be easy to construct, can have
Effect reduces construction cost.And when spring energy dissipating bed course Local Damaged in use, it is simple to carry out replacement operation to it,
It can ensure the safe operation of canopy cave in time.
