Description

Technical Field

[0001] The utility model relates to the field of highway guardrails, in particular to a highway guardrail for traffic engineering. Background Art

[0002] Highway guardrails are a type of transportation infrastructure on highways. Highways have high traffic volume and speed, and guardrails need to be installed on both sides of the road so that they can play a certain protective and buffering role when a traffic accident occurs, effectively reducing the occurrence of serious accidents to a certain extent.

[0003] Existing highway guardrails generally have columns arranged at intervals on both sides of the road, concrete is injected into the columns, and then corrugated steel plates are connected between adjacent columns. Some highway guardrails also have water barriers arranged on the side of the steel plate close to the road. After water is injected into the water barriers, they can play a further buffering role in the event of an accident.

[0004] With respect to the above-mentioned related technologies, when the water barriers installed on the side of the existing highway guardrail close to the highway are hit by a car, when the collision angle of the car is small, the impact force along the length direction of the guardrail is likely to push the water barriers to slide and displace. The water barriers with large displacement deviate from the preset impact resistance position, causing the car to easily directly hit the steel body of the guardrail, seriously reducing the safety factor of the car during high-speed collision. At the same time, the water barriers that are hit at a small angle obliquely are also easily pushed onto the highway, affecting the safety of subsequent cars. In summary, the existing highway guardrails have the problem that the water barriers in front of the guardrails are easily scattered by collision. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a highway guardrail for traffic engineering, so as to solve the technical problem that the water barriers in front of the guardrails of the existing highway guardrails are easily collided and scattered.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a highway guardrail for traffic engineering, comprising upright posts arranged at intervals along both sides of the road, wherein a baffle is fixedly connected to the side of the upright post close to the road, a fixing plate is fixedly connected to the bottom end of the baffle at intervals along the length direction, the fixing plate extends toward the center of the road and is connected to a boss, a water tank is placed on the side of the fixing plate close to the road, and a concave platform for matching the boss is provided at the bottom end of the water tank.

[0007] By adopting the above technical solution, a baffle is connected to one side of the column, and a raised boss structure is fixedly connected to the bottom end of the baffle, and a concave structure matching the boss is provided at the bottom of the water tank. This can effectively prevent the water tank from being displaced when impacted, thereby further reducing the damage to people in the vehicle caused by the car accident.

[0008] The utility model is further configured that the column comprises three steel pipes arranged in a triangle, and a reinforcing column is obliquely connected between the three steel pipes arranged in a triangle.

[0009] By adopting the above technical solution, the three steel pipes arranged in a triangle are interconnected by reinforcing the columns, which can effectively improve the ability of the columns to resist horizontal impact.

[0010] The utility model is further configured that the bottom end of the column includes a portion that needs to be buried in the ground, and the column is not connected to a reinforcing column at the portion that needs to be buried in the ground.

[0011] By adopting the above technical solution, after the bottom end of the column is buried in the ground and concrete is injected, the ability of the column to resist horizontal impact can be further improved.

[0012] The utility model is further configured that a convex strip is arranged along the length direction of the water tank on one side facing the road, and the convex strips are arranged at intervals along the height direction of the water tank.

[0013] By adopting the above technical solution, when the car collides with the water tank, deformation can be generated first to alleviate part of the impact force.

[0014] The utility model is further configured that partitions are arranged at intervals along the length direction inside the water tank.

[0015] By adopting the above technical solution, the structural strength of the water tank can be effectively improved.

[0016] The utility model is further configured that a plurality of water permeable holes are opened on the partition, and the water permeable hole at the bottom of the partition can communicate with two sides of the partition at the bottom end of the water tank.

[0017] By adopting the above technical solution, the water-permeable holes can be connected to various places in the water tank, so that the water tank can be filled with water more easily.

[0018] The utility model is further configured that a side of the fixing plate facing the road is provided with a corrugated protrusion, and a side of the water tank facing the fixing plate is provided with a corrugated depression matching the fixing plate.

[0019] By adopting the above technical solution, the water tank is further stabilized.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. The utility model connects a baffle plate to one side of the column, and fixes a raised boss structure at the bottom of the baffle plate, and at the same time, a concave structure matching the boss is provided at the bottom of the water tank. After the water tank is filled with water, due to its own gravity and the mutual engagement between the boss and the concave, the water tank can be effectively prevented from being displaced when impacted, thereby further reducing the damage to the occupants of the vehicle caused by the car accident;

[0022] 2. The utility model is provided with three small-diameter column structures arranged in a triangle, and reinforcing rods are obliquely connected between the three columns. After concrete is injected into the hollow columns, the column structure arranged in a triangle can provide a more stable support effect and better resist horizontal impact force under the premise of having an installation area similar to that of traditional large-diameter steel columns.

After the fixing ring 7 is sleeved on the column 1 and passes through the through hole 9 on the baffle 2, the baffle 2 is limited by a latch 8 on the side away from the column 1. The bottom end of the baffle 2 is fixedly connected with a fixing plate 4 at intervals along the length direction. The fixing plate 4 extends toward the center of the road and is connected to a boss 5. Specifically, the boss 5 has a trapezoidal structure and can be easily The water tank 3 is easily engaged with the concave platform at the bottom of the water tank 3, and can effectively prevent the water tank 3 from sliding in the horizontal direction after water is filled in the water tank 3. The water tank 3 is placed on the side of the fixing plate 4 close to the road, and the bottom of the water tank 3 is provided with a concave platform 6 for matching the convex platform 5. The side of the water tank 3 facing the road is provided with convex strips 10 along the length direction, and the convex strips 10 are arranged at intervals along the height direction of the water tank 3. The convex strips 10 face the direction of the road. When the car collides with the water tank 3, it can be deformed first to alleviate part of the impact force.

[0034] See also Figure 2-6 The interior of the water tank 3 is arranged with partitions 11 at intervals along the length direction. The partitions 11 serve as reinforcing ribs in the water tank 3, which can effectively improve the structural strength of the water tank 3 and prevent serious deformation of the water tank 3. A plurality of water holes 12 are provided on the partitions 11. Specifically, a water injection port 13 is also provided at the top of the water tank 3, and water is injected into the water tank 3 through the water injection port 13. A sealing cover is also provided on the water injection port 13.

[0036] Embodiment 2

[0037] A highway guardrail for traffic engineering, such as Figure 1-6As shown, on the basis of Example 1, the difference from Example 1 is that the column 1 includes three steel pipes arranged in a triangle, and the three steel pipes arranged in a triangle are obliquely connected with a reinforcing column. The three steel pipes arranged in a triangle are interconnected by the reinforcing column, which can effectively improve the ability of the column 1 to resist horizontal impact. The bottom end of the column 1 includes a part that needs to be buried in the ground. The column 1 is not connected to the reinforcing column at the part that needs to be buried in the ground. After the bottom end of the column 1 is buried in the ground, concrete is injected, which can further improve the ability of the column 1 to resist horizontal impact.

[0038] The working principle of the utility model is as follows: when the highway guardrail is impacted by a car at high speed, the convex strips 10 on the outer wall of the water tank 3 are deformed first, and then the water tank 3 is deformed, and the partition 11 inside the water tank 3 is further deformed as a reinforcing rib, which has a buffering effect on the impact of the car. When the car has a large mass and a fast speed, a large impact force rushes toward the water tank 3, and the concave platform 6 at the bottom end of the water tank 3 cooperates with the convex platform 5 structure of the fixing plate 4 to effectively prevent the water tank 3 from being displaced in the horizontal direction, and the corrugated structure between the water tank 3 and the baffle 2 can effectively prevent the water tank 3 from being displaced in the vertical direction, so that the water tank 3 can fully play a buffering role, and then the baffle 2 and the column 1 will undertake the subsequent buffering task, further buffering the vehicle, and effectively ensuring the life safety of the people in the vehicle.
