Abstract
The utility model discloses a vehicle impact prevention energy-absorbing guardrail for a channel, which comprises a flexible tubular restraining member and granular energy-absorbing materials, wherein the granular energy-absorbing materials are filled in the flexible tubular restraining member, and the guardrail is arranged on the inner side wall of the channel. The utility model utilizes the strong constraint force, high elasticity and high durability of the flexible tubular constraint component, has good energy absorption effect after being filled with granular energy absorption materials, and can effectively protect people, vehicles and pipelines when being impacted; the installation of the upright post is not needed, and the device is particularly suitable for being used in a corrugated steel structure channel in which the guardrail upright post is not suitable to be installed; simple structure, low cost and convenient replacement after damage.
Description
Technical Field
The utility model relates to the technical field of road engineering, in particular to a vehicle impact prevention energy absorption guardrail for a channel.
Background
When a vehicle collides with a wall in a channel in an accident, the wall of the channel is of a corrugated steel pipe structure made of thin steel plates and is easy to deform or tear due to collision, so that the steel wall loses support force and the channel collapses. If a common corrugated steel guardrail is arranged, the corrugated steel guardrail upright post supported by the corrugated steel guardrail cannot be arranged. Because the corrugated steel channel is substantially closed in cross section, the base plate is also corrugated steel, and if the upright is connected to the corrugated steel channel base plate or the side wall of the corrugated steel channel, the energy generated by vehicle impact can deform or tear the corrugated steel plate of the channel pulled by the upright or the guardrail, and damage the strength of the channel. In addition, the upright posts and the corrugated guardrails are made of steel and have high strength. The columns and guardrails themselves may also damage the walls of the corrugated steel channels after an accident.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims to provide a vehicle impact prevention energy-absorbing guardrail for a passage, which can effectively protect vehicles, personnel and the passage when the vehicle impacts in the passage.
The technical scheme is as follows: the utility model discloses a vehicle impact prevention energy-absorbing guardrail for a channel, which comprises a flexible tubular restraining member and granular energy-absorbing materials, wherein the granular energy-absorbing materials are filled in the flexible tubular restraining member, and the guardrail is arranged on the inner side wall of the channel.
By means of the elasticity and the constraint property of the flexible tubular constraint component, the granular energy-absorbing material filled inside can effectively relieve the impact force.
Further, the flexible tubular restraining member is disposed within the plastic housing.
And the flexible tubular restraining members are vertically arranged in a plurality of rows within the plastic housing. Distributing the impact forces over the plurality of flexible tubular restraining members, reducing the likelihood of breakage thereof.
Furthermore, the flexible tubular restraining member is a fabric rubber tube or a fabric plastic tube, has good ductility and high restraining strength, and is not easy to damage.
Furthermore, the granular energy absorption material is sand or sandy soil.
Further, the guardrail is arranged on the inner side wall of the channel through a bracket. The installation can be fixed installation or suspension installation.
Furthermore, the guardrails are arranged on the inner side wall of the channel at intervals along multiple sections of the extending direction of the channel, and the sections are not connected.
Further, the passageway is corrugated steel structure passageway, and this guardrail structure is perfect to have solved the problem that should not install the guardrail stand in the corrugated steel structure passageway.
Has the advantages that: compared with the prior art, the utility model has the advantages that: the high restraint force, the high elasticity and the high durability of the flexible tubular restraint member are utilized, the energy absorption effect is good after the granular energy absorption material is filled, and people, vehicles and pipelines can be effectively protected when the flexible tubular restraint member is impacted; the installation of the upright post is not needed, and the device is particularly suitable for being used in a corrugated steel structure channel in which the guardrail upright post is not suitable to be installed; simple structure, low cost and convenient replacement after damage.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical scheme of the utility model is further explained by combining the attached drawings.
The vehicle collision prevention energy absorption guardrail for the channel shown in figure 1 is characterized in that the guardrail 1 is arranged on the inner walls of two sides of the channel.
The barrier 1 comprises a flexible tubular restraining member 101 which may be a fabric rubber tube or a fabric plastic tube, and a particulate energy absorbing material 102 which may be sand or sandy soil. The particulate energy absorbing material 102 is filled in the flexible tubular restraining member 101 and closed. The flexible tubular restraining member 101 has strong restraining force, high elasticity and high durability, and is filled with the granular energy-absorbing material 102 to achieve good energy-absorbing effect, so that people, vehicles and pipelines can be effectively protected when the flexible tubular restraining member is impacted.
To further distribute the impact forces, flexible tubular restraining member 101 is disposed within plastic housing 103, and when disposed, flexible tubular restraining member 101 is disposed in plurality in transverse and vertical alignment. And, can lay this guardrail 1 of multiunit at interval along the extending direction of passageway, carry out all-round protection.
During installation, the guardrail 1 does not need to be provided with guardrail columns in the channel, can be directly arranged on the inner side wall of the channel through the support 2, can be fixedly arranged and can also be arranged in a suspension mode, and during installation, the guardrail 1 can be lifted off at a certain height.
This guardrail 1 is particularly useful for the corrugated steel structure passageway of unsuitable installation guardrail stand.
