Abstract
The utility model discloses 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 utility model on the basis retaining original guardrail, can be increased guardrail; The horizontal tube that can stretch in the horizontal direction can provide axial support power, and whole bracing means is door type structure, makes the guardrail that is reinforced firmer; Original corrugated guardrail can also be raised after increasing and install, or second row corrugated guardrail is installed, the crashworthiness of whole guardrail is promoted greatly.
Description
Technical field
The utility model 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.
Utility model content
The purpose of this utility model is that providing a kind of on the basis retaining original guardrail, can carry out the speedway waveform anticollision barrier heightening device of heightening and consolidation to guardrail.
The technical solution realizing the utility model object 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 utility model compared with prior art, its remarkable advantage:
(1) speedway waveform anticollision barrier heightening device of the present utility model on the basis retaining original guardrail, can be increased guardrail.
(2) speedway waveform anticollision barrier heightening device of the present utility model 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 utility model after increasing, or installs second row corrugated guardrail, and the crashworthiness of whole guardrail is promoted greatly.
Below in conjunction with accompanying drawing, the utility model 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 the utility model speedway waveform anticollision barrier heightening device.
Detailed description of the invention
Composition graphs 3:
