Abstract
Description
Technical Field
[0001] The present application relates to the technical field of highway traffic safety facilities, and specifically discloses a deceleration and anti-collision guardrail for highway traffic safety facility engineering. Background Art
[0002] Highway traffic safety facilities are a general term for facilities such as pedestrian underpasses, pedestrian bridges, and traffic lights installed along roads to ensure the safety of both drivers and pedestrians and maximize the effectiveness of roads. Among these, speed reduction and anti-collision guardrails, installed along roadsides, particularly on highways, are essential.
[0003] The deceleration and anti-collision guardrail mainly absorbs impact energy through its own elastic-plastic deformation, friction, and body deformation, thereby reducing the severity of the accident and protecting the safety of people in the car, road buildings, and other objects outside the road.
[0004] During the long-term use of public transportation, the slopes on both sides of the road will inevitably experience varying degrees of settlement, causing the position of the deceleration and anti-collision guardrail to be lowered and unable to achieve the original protective performance. When this phenomenon occurs, the guardrail needs to be raised and reinforced in time to ensure the normal function of highway traffic safety facilities.
[0005] At present, since the deceleration and anti-collision guardrail is fixed by directly burying the bottom of the pillar into the ground, when lifting the guardrail, a hydraulic press is usually used to grab the pillars of the deceleration and anti-collision guardrail and lift it upward. During this process, due to the gripping of the hydraulic press claws, the pillars of the deceleration and anti-collision guardrail are easily deformed, which not only affects the appearance of the deceleration and anti-collision guardrail, but also affects the normal performance of the deceleration and anti-collision guardrail to a certain extent. As a result, after the deceleration and anti-collision guardrail is lifted, the concave parts on the surface of the pillars need to be repaired, which not only has a large workload, but also reduces the efficiency of lifting and reinforcing the guardrail. Therefore, in view of this, the inventor provides a deceleration and anti-collision guardrail for highway traffic safety facilities engineering to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to solve the problem that after the traditional deceleration and anti-collision guardrail is lifted, the concave parts on the surface of the guardrail column need to be repaired, which reduces the efficiency of lifting and reinforcing the guardrail.
[0007] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a deceleration and anti-collision guardrail for highway traffic safety facility engineering, including columns evenly arranged on both sides of the road and corrugated plates arranged between adjacent columns, the adjacent corrugated plates are connected end to end in sequence, and the bottom of the columns are provided with fixed piles buried in the ground on both sides of the road, the top of the fixed piles extends into the columns and is provided with matching grooves, a number of matching blocks are evenly provided in the matching grooves, there are gaps between adjacent matching blocks and between the matching blocks and the bottom of the matching grooves, a cavity that connects the top surface of the column with the matching groove is vertically provided in the column, and the top of the column is detachably connected to an end cover that can cover the top of the cavity.
[0008] The principles and effects of this basic solution are:
[0009] Compared with the prior art, the present invention fixes the columns and corrugated plates as a whole by setting columns and fixing piles, and burying the fixing piles in the ground. At the same time, the top of the fixing pile is extended into the column to improve the structural strength and impact resistance of the column as a whole. In the process of lifting the deceleration and anti-collision guardrail as a whole, external accessories (such as hooks, ropes, etc.) are extended into the gaps between adjacent matching blocks, so that the entire deceleration and anti-collision guardrail can be lifted upward under the action of the hydraulic press. Moreover, since the matching blocks are directly provided on the fixing piles, the situation that the fixing piles and the columns are separated during the lifting process can be avoided. Since it is not necessary to clamp the easily deformed parts of the deceleration and anti-collision guardrail during the lifting process, the deceleration and anti-collision guardrail will not produce deformations such as depressions, which solves the problem that after the traditional deceleration and anti-collision guardrail is lifted, the depressions on the surface of the guardrail columns need to be repaired, which reduces the efficiency of lifting and reinforcing the guardrail.
[0010] Furthermore, the column comprises an inner shell, an outer shell, and a filling cavity disposed between the inner and outer shells. The top of the fixing pile is located within the inner shell, with a plurality of support plates disposed between the top and the inner wall of the inner shell. The interplay between the inner and outer shells allows the filling cavity to be filled with concrete, for example, reducing the overall construction cost of the column while improving its structural performance. The provision of the support plates further enhances the connection between the inner shell and the fixing pile, effectively preventing the column from separating from the fixing pile during lifting, which could damage the entire speed reduction and anti-collision barrier.
[0011] Furthermore, the filling cavity is provided with a plurality of reinforcing rods respectively connected between the inner shell and the outer shell. The reinforcing rods can improve the connection performance between the inner shell and the outer shell.
[0012] Furthermore, elastic blocks are provided between the two side surfaces of the inner shell that are parallel to the road and the fixing piles. Since in actual use, vehicles usually collide from the road to the guardrail, providing elastic blocks in this direction can effectively improve the anti-collision performance of the deceleration and anti-collision guardrail and reduce the intensity of vehicle impact.
[0013] Furthermore, the bottom of each column is provided with a base fixed to the ground on both sides of the road, which can further improve the stability of the column installation.
[0014] Furthermore, a circular plate is provided between the corrugated plate and the columns, with opposite sidewalls of the circular plate connected to the inner wall of the corrugated plate and the outer side of the columns, respectively. The circular plate facilitates the connection between the corrugated plate and the columns, and can also utilize its elastic-plastic deformation to mitigate impact forces, facilitating the repair and replacement of structural components such as the corrugated plate and the columns.
[0015] Furthermore, a connecting plate is provided between adjacent uprights, and a circular plate is provided between the connecting plate and the corrugated plate, so as to improve the overall structural performance of the deceleration and anti-collision guardrail.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0021] The reference numerals in the drawings of the specification include: corrugated plate 1, fixed pile 2, base 3, outer shell 4, circular plate 5, end cover 6, inner shell 7, matching block 8, filling cavity 9, reinforcing rod 10, support plate 11, elastic block 12, and connecting plate 13.
[0022] A deceleration and anti-collision guardrail for highway traffic safety facilities engineering, for example Figure 1 As shown: It includes columns evenly arranged on both sides of the road and corrugated plates 1 arranged between adjacent columns, and adjacent corrugated plates 1 are in contact with each other end to end. Figure 2 As shown, a base 3 is provided at the bottom of the column to be fixed to the ground on both sides of the road. The base 3 is fixed to the ground by rivets, and an end cover 6 is fastened to the top of the column to cover the top of the column.
[0023] like Figure 2 As shown, the column consists of an inner shell 7, an outer shell 4 and a plurality of reinforcing rods 10 arranged between the inner shell 7 and the outer shell 4, and the bottom of each inner shell 7 is provided with a fixing pile 2 buried in the ground on both sides of the road, the top of the fixing pile 2 passes through the base 3 and extends into the interior of the inner shell 7 and is provided with a matching groove, and a number of matching blocks 8 are evenly arranged in the matching groove. There are gaps between adjacent matching blocks 8 and between the matching blocks 8 and the bottom of the matching groove. The bottom of the inner shell 7 is connected to the base 3, and the interior of the inner shell 7 is hollow, so that a cavity is vertically formed in the inner shell 7 to connect the top surface of the column with the matching groove. The top of the fixing pile 2 is located in the inner shell 7 and a number of support plates 11 are provided between it and the inner wall of the inner shell 7. The end cover 6 at the top of the column protects the various accessories in the column.
[0024] Since in actual use, the direction of vehicle collision is usually from the road to the guardrail, an elastic block 12 is provided between the two side surfaces of the inner shell 7 parallel to the road direction and the fixed pile 2, thereby improving the anti-collision performance of the deceleration anti-collision guardrail and reducing the intensity of vehicle collision.
[0025] like Figure 3 As shown, connecting plates 13 are provided between adjacent columns. The corrugated plate 1 is connected to the columns and to the connecting plates 13 through circular plates 5. The opposite side walls of the circular plates 5 are respectively connected to the inner wall of the corrugated plate 1 and the outer side of the columns (outside of the connecting plates 13) by means of rivets.
[0026] During the lifting process of the deceleration and anti-collision guardrail, the resistance encountered is mainly the gravity of the deceleration and anti-collision guardrail itself and the friction caused by the squeezing of the road concrete layer on the fixed pile 2. When the resistance is too large, it is easy to cause the separation between the column and the fixed pile 2. In this embodiment, the four support plates 11 located between the four corners of the inner shell 7 and the outer wall of the fixed pile 2 can improve the connection performance between the inner shell 7 and the fixed pile 2, and effectively avoid the separation of the column and the fixed pile 2 during the lifting process, which may cause damage to the entire deceleration and anti-collision guardrail.
[0027] In this embodiment, the columns and the corrugated plate 1 are fixed as a whole by burying the fixing piles 2 in the ground, and the tops of the fixing piles 2 are extended into the columns to improve the structural strength and impact resistance of the columns as a whole. In the process of lifting the deceleration and anti-collision guardrail as a whole, external accessories (such as hooks, ropes, etc.) are extended into the gaps between adjacent matching blocks 8, so that the entire deceleration and anti-collision guardrail can be lifted upward under the action of the hydraulic press. Moreover, since the matching blocks 8 are directly provided on the fixing piles 2, the situation in which the fixing piles 2 and the columns are separated during the lifting process can be avoided. Since it is not necessary to clamp the easily deformed parts of the deceleration and anti-collision guardrail during the lifting process, the deceleration and anti-collision guardrail will not produce deformations such as depressions, which solves the problem that after the traditional deceleration and anti-collision guardrail is lifted, the depressions on the surface of the columns of the guardrail need to be repaired, thereby reducing the efficiency of lifting and reinforcing the guardrail.
[0028] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
