Abstract
The invention discloses a device capable of heightening expressway waveform anti-collision guardrails. The device comprises heightening stand columns and stretchable horizontal pipes, wherein the heightening stand columns are nested and matched with stand columns of original waveform anti-collision guardrails; the stretchable horizontal pipes are adjustable in length and capable of bearing axial force after being adjusted; the heightening stand columns are arranged at two ends of each stretchable horizontal pipe and are perpendicular to the horizontal pipes. The device is capable of heightening the guardrails on the basis that the original guardrails are retained; the horizontal pipes capable of stretching and retracting in the horizontal direction are capable of providing axial support force; a whole reinforcing device is of an n-shaped structure, so that the reinforced guardrails are relatively firm; the original waveform guardrails can be heightened and mounted after being heightened; or a second row of waveform guardrails is mounted; the anti-collision performance of the whole guardrails can be greatly improved.
Description
Technical field
The invention belongs to expressway safety guard technology field, particularly a kind of speedway waveform anticollision barrier heightening device.
Background technology
Existing anti-collision guard rail for highways generally adopts two parallel guardrails, as Fig. 1 and Fig. 2, the speedway of operation phase, intermediate isolating band anticollision barrier is crossed in frequent generation to lose control of one's vehicle, fall subtend track, Facing Movement vehicle is often hidden too late, there is with it fierce collision, and then cause the serious accident of a chain of automobile crash to occur, casualties is numerous, property loss is heavy, this scene occurs in news report of being everlasting, Highway Maintenance department need a kind of economical, effectively, solution easily, avoid the generation of this type of accident.
The most direct solution is exactly install higher anticollision barrier in the isolation strip that speedway is middle, but face two problems like this, one is that existing speedway is provided with guardrail all, again removes that to install higher guardrail cost more very high, and difficulty of construction is large; Although two is that guardrail after increasing can prevent vehicle from crossing, highly more built on the sand high, easily there is vehicle and sever situation through intermediate isolating band after guardrail.
Summary of the invention
The object of the present invention is to provide a kind of can retain original guardrail basis on, carry out the speedway waveform anticollision barrier heightening device of heightening and consolidation to guardrail.
The technical solution realizing the object of the invention is:
A kind of speedway waveform anticollision barrier heightening device, comprise and can bear the flexible horizontal tube of axial force after adjustment with the heightening upright post of the column nested arrangements of former highway waveform anticollision barrier and adjustable length, heightening upright post is arranged on the two ends of flexible horizontal tube, and vertical with horizontal tube.
The present invention compared with prior art, its remarkable advantage:
(1) speedway waveform anticollision barrier heightening device of the present invention on the basis retaining original guardrail, can be increased guardrail.
(2) speedway waveform anticollision barrier heightening device of the present invention can stretch in the horizontal direction, and can provide axial support power, makes whole bracing means be door type structure, makes the guardrail that is reinforced firmer.
(3) original corrugated guardrail can also raise and install by speedway waveform anticollision barrier heightening device of the present invention after increasing, or installs second row corrugated guardrail, and the crashworthiness of whole guardrail is promoted greatly.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the schematic cross-sectional view of existing speedway waveform anticollision barrier.
Fig. 2 is the schematic longitudinal section of existing speedway waveform anticollision barrier.
Fig. 3 is the structural representation of speedway waveform anticollision barrier heightening device of the present invention.
