Description
Technical field
The present invention relates to highway barrier guard technology, particularly a kind of energy-absorbing guide type suitable for sharp radius curve section
Anti-collision facility and unit block, are conducive to meeting sharp radius curve section pervasive with structure to the comprehensive safety performance of guardrail facility
Property require, the minor radius refers to turning radius≤150 meter, and >=30 meters.
Background technology
Man of Shu Duo mountain countries of China, mountain area is more, and Plain is few, and complicated topographical conditions are various, can not in planning of highways design process
The meeting for avoiding is linear using sharp radius curve.Because sharp radius curve section can produce larger centrifugal force, driver to vehicle
Sighting distance is poor, and vehicle collision guardrail accident easily occurs, and collision angle is often bigger than normal, and driver and conductor is vulnerable to extremely strong
Collision impact, it is therefore desirable to which highway barrier facility has good energy-absorbing effect and guide function, and barrier functionality reliability；Together
When sharp radius curve section linear diversity and particularity, it is desirable to matching and versatility when highway barrier facility is longitudinally disposed
Well, various curve sections are applicable to.
The current commonly used guardrail form of highway is including corrugated beam barrier, concrete guardrail, Cable Barrier etc..Though
The security protection performance of right these existing guardrails meets the application demand of highway general standard section, but inventors believe that, for
For the more unfavorable sharp radius curve section of impact conditions, such as turning radius≤150 meter, the stop of existing guardrail, buffering with
It is oriented to the special requirement of shelter needed for the comprehensive safety performance of three aspect compositions does not reach the section.Such as concrete guardrail conduct
Though stiff safety fence collides the buffering energy-absorbing of vehicle and driver and conductor to minor radius section wide-angle with good barrier functionality
Effect and guide function are poor；Though corrugated beam barrier and Cable Barrier as inclined flexible safety fence with good pooling feature,
Vehicle barrier functionality to larger collision energy is poor, and energy-absorbing effect is limited, thus existing guardrail facility cannot be applied to it is small
Radius curve section.Additionally, conventional the be oriented to bumper in highway intercommunication ring road shunting triangle end is that one kind has both well
The facility of buffering energy-absorbing effect and guide function, but its point-like protection for being only applicable to certain FX on highway, it is impossible to real
The wire safeguard function of the longitudinal elongated guardrail in existing sharp radius curve section.
The content of the invention
The present invention is for defect or deficiency present in prior art, there is provided a kind of suction suitable for sharp radius curve section
Can guide type anti-collision facility and unit block, be conducive to meeting sharp radius curve section to the comprehensive safety performance of guardrail facility with
The requirement of structure universality, the minor radius refers to turning radius≤150 meter, and >=30 meters.
Technical scheme is as follows：
A kind of energy-absorbing guide type anti-collision unit component, it is characterised in that be sleeved on column including column and successively

Vertical yardstick of the vertical yardstick of the first energy-absorbing case less than the second energy-absorbing case.
The column is cylindrical structure.
A kind of energy-absorbing guide type anti-collision facility suitable for sharp radius curve section, it is characterised in that including by splicing
The anti-collision structure that be spliced for a kind of several above-mentioned energy-absorbing guide type anti-collision unit components by bolt, the anti-collision structure is edge
The elongated guardrail in longitudinal direction in sharp radius curve section, the minor radius refers to turning radius≤150 meter, and >=30 meters.
Technique effect of the invention is as follows：A kind of energy-absorbing guide type anticollision suitable for sharp radius curve section of the invention sets
Apply and unit block, the wire safeguard function of the longitudinal elongated guardrail in sharp radius curve section can be realized, have both guardrail longitudinally logical
Safeguard function long and bumper good guidance energy-absorbing effect, and process is simple, various sharp radius curve sections are common to, to reach
Solve the problems, such as that existing utility sharp radius curve section does not apply to.
The casing energy-absorbing that the present invention applies to sharp radius curve section (minor radius i.e. turning radius are 30m~150m) is led
To formula anti-collision facility, it passes through, and longitudinal direction is elongated to set that multiple energy absorbing efficiencies are high, good buffer effect energy-absorbing unit is bent minor radius
Part of path collides vehicle and driver and conductor provides good pooling feature, reduces injury journey of the collision impact to driver and conductor
Degree；And its steering capability is improved by setting up directive wheel, realize smooth guiding of the collision vehicle in sharp radius curve section, it is to avoid
Vehicle hinders because stumbling or irregular traveling causes pernicious second accident to occur.Additionally, in terms of minor radius radian matching, due to casing
Energy-absorbing guide type anti-collision facility longitudinal direction cell node size is small, it is easier to realizes the linear matching of minor radius, and is divided on the facility
The energy-absorbing bucket put for parallelogram, its angle can according to Practical Project minor radius size carry out matching setting (such as with 30m~
The box angle scope that 150m scope minor radius section matches is 30 °~70 °, and angle is adjusted according to different radii, is reached more
Good energy-absorbing effect, the i.e. smaller guiding energy-absorbing effect to vehicle of angle is more excellent, reduces vehicle and stumbles the probability of resistance), it is pervasive
Property it is stronger, can also reduce the processing of sharp radius curve section anti-collision facility and construction technology difficulty, anti-collision facility has been reached standard
Change, generalization is required, box angle is smaller more favourable to traffic safety, has ensured the operation in highway sharp radius curve section
Safety.
