Description
Technical field
The utility model relates to the semi-rigid crashproof dangerous guardrail that subtracts of a kind of speedway; more particularly; the utility model relates to the semi-rigid anticollision barrier of a kind of speedway; it is to utilize soil matrix; column; spring; leghole; the chute of the distortion of crossbeam and friction of crossbeam ripple and junction slides up and down and absorbs collision energy; and force errant vehicle to change direction by the friction eceleration and the interactive distortion absorption of the spring collision energy of crossbeam ripple; return to normal travel direction; prevent that vehicle is run-off-road; safety with protection vehicle and passenger; prevent that vehicle is bound on other tracks by reaction force, reduce the loss that traffic accident causes.
Background technology
At present, because turnpike driving speed is fast, rate of traffic flow is big, on speedway safety guide rail must be set, and existing protective guard is generally stiff safety fence, semi-rigidity rail, flexible safety fence.Stiff safety fence is a kind of constant basically concrete block construction or guardrail board and the direct-connected structure of column, its good rigidly, but construction is complicated, and it is long-pending big to account for the road surface, and the cost height is not attractive in appearance; Semi-rigidity rail intensity is low, poor toughness, impact resistance are not strong, safeguards inconvenience; The flexible safety fence construction is complicated, technical difficulty is high, not easy care." a kind of intelligent guardrail board; comprise column and guardrail; guardrail is made by the PVC plastics; the guardrail surface is provided with the light belt of being made up of luminous raw material composite construction layer, is reserved with the hole of perforation in it, wears wire rope in the hole is disclosed in the Chinese patent " notification number: CN2461951Y; the day for announcing is November 28 calendar year 2001; name is called ' intelligent guardrail board ' "; Also be provided with the security warning window on the guardrail, window be provided with from the hook, this is linked up with an end and is provided with balance weight body by a chain relative side, on this balance weight body fixedly the interlocking mechanism wire rope connect next piece guardrail board from locking and hanging hook, the caution window in the installing colored ribbon.If vehicular traffic collision guardrail, colored ribbon flies out automatically ".Though this technology has certain warning function, its weak point is that intensity is low, poor toughness, impact resistance are strong, safeguard inconvenience, and operability is poor, manufacturing is complicated, cost is expensive, and can not effectively prevent to collide vehicle and go out the road surface.
Summary of the invention
Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, provide a kind of simple in structure, the semi-rigid crashproof dangerous guardrail that subtracts of improved speedway safe and convenient to use utilizes this semi-rigid crashproof dangerous guardrail that subtracts, can improve intensity, toughness, the shock resistance of guardrail significantly, delay the application life of guardrail, prevent that effectively vehicle is run-off-road, reduce the loss, improved safety factor, and this guardrail is easy to maintenance, installs simply, has the very strong crashproof dangerous function that subtracts.
The purpose of this utility model is achieved through the following technical solutions.
The utility model speedway is semi-rigid crashproofly to be subtracted dangerous guardrail and comprise: rod, waveform bridge spring shim, waveform bridge protective railings plate are impacted in sleeve triangle sitting posture column, spring, screw, energy dissipating (has the crossbeam ripple on this guardrail board, crossbeam ripple direction is identical with waveform bridge spring direction, omit the setting-out of crossbeam ripple on the figure, hereinafter to be referred as waveform bridge protective railings plate.), the night safe warning lamp forms.Describedly crashproofly subtract dangerous guardrail, tamp hollow column, water the sleeve that sand tamps column with pitch with concrete mortar by pre-buried sleeve triangle sitting posture column part in soil; Spring, waveform bridge spring, pad are connected on the sleeve triangle sitting posture column by screw, with screw waveform bridge protective railings plate are connected on the waveform bridge spring shim again and form user mode with column.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1. make simple.Sleeve triangle sitting posture column, common spring, the manufacturing of waveform bridge protective railings all are existing mature technology;
2. constructing operation is convenient.During land-based construction sleeve triangle sitting posture column should be buried the soil matrix part and be embedded in advance in the soil matrix, again spring, waveform bridge protective railings be connected by screw during anticollision barrier to be installed, reserve warning at night lamp place at guardrail again and set up warning lamp and get final product;
3. the function of this guardrail.Allomeric function is semi-rigid anticollision barrier, below the small form bridge protective railings be that central pony car is when knocking, prevent that promptly vehicle from down going here and there, when up running quickly as vehicle, force vehicle to change direction by top big waveform bridge protective railings, return on the travel direction by force, big-and-middle waveform bridge protective railings mainly is to prevent that big driving from going out the road surface, top small form bridge mainly is the impact force that strengthens intensity and slow down vehicle, play the energy dissipating effect, in whole spring structure process, all be that distortion by spring absorbs and changes impact force, prevent that effectively vehicle from going out the road surface, slow down of the effect of the anti-force of guardrail by spring again car, reduce excessive reaction force, the excessive and loss that brings of the resilience of avoiding vehicle;
4. intensity height.Sleeve triangle sitting posture column has changed direct burial column in the past, and with the hollow column of concrete casting, had both strengthened the intensity of column, has reduced the cost of column again;
5. good toughness, impact resistance is strong.When vehicle knocks guardrail, can stretch one by one of spring and contract, increase toughness, reduce slow impact force, reduce loss;
6. the safety factor height can effectively reduce loss.When running into vehicle collision, by the distortion of spring, both can reduce the damaged condition of casualties and vehicle, can reduce the loss of guardrail again;
7. easy to maintenance.Cause guardrail when loss when running into huge collision, only need change guardrail board, the general destruction that can not cause spring, maintenance speed is fast, has alleviated maintenance personal's labour intensity greatly.
