Qingdao Taicheng Transportation Facilities Co., Ltd. is a technological innovation enterprise invested by Henger Group. Its headquarters is located in Jinkou Industrial Park, Qingdao. Taicheng Transportation has an innovative scientific research team, advanced manufacturing technology, first-class production facilities, and perfect testing methods. , reliable product quality, enthusiastic after-sales service, devoted to the great cause of improving China's road safety.

 

 

The impact-resistant and energy-absorbing rotating guardrail independently developed and designed by Taicheng Transportation has broken the technological monopoly of Korean and American countries and filled the market gap of China's rotating guardrail. The product has more than 20 national patents, and has successfully passed the collision test of small cars (family cars), buses and large trucks in the highway test site of the Ministry of Communications, and the test results and collision data are at the international leading level.

 

 

The new series of rotating anti-collision barriers have been widely used in South Korea, Japan, the United States, the United Arab Emirates and other countries. The accident rate, economic loss rate and accident fatality rate of the installed road section have been reduced by more than 95%, which has greatly protected the lives of pedestrians. Property safety provides a reliable guarantee and strong shield for road safety. It is believed that in the near future, the new type of rotating anti-collision guardrail will be popularized on China's highways and accident-prone sections, introducing innovative protection design for China's road environment, bringing leap-forward protection effects for road safety, and becoming a life project for the benefit of future generations. .

 

 

The company will always adhere to the corporate tenet of "not forgetting the original intention, people-oriented, and technological innovation", to build a first-class transportation facility enterprise with international competitiveness, to provide the society with high-quality new rotating anti-collision guardrails, and to protect the road safety of the country and the world. convoy.

 

 

 

 

 

 

 

 

 

 

 

 

Product description

The rotating guardrail adopts the "one column and four columns" method. By strengthening the performance and installation method of the columns and guardrails, it can effectively prevent cars from passing through the guardrail and driving out of the driving lane. It pioneered the use of a rotating structure to support the elastic, anti-collision and wear-resistant rotating barrel on the column, so that the rotating barrel can rotate freely on the column. This free rotation of the rotating barrel decomposes the impact force of the car. In this way, the impact force perpendicular to the direction of the guardrail is decomposed into the direction parallel to the guardrail, and is effectively absorbed and reduced by the rotating barrel, thereby effectively reducing the consequences of traffic accidents.

 

 

The impact-resistant rotating guardrail is a "revolution" in high-speed guardrails.

 

At present, this product has obtained 22 invention patents and is widely used in South Korea, Japan, the United States and other countries. The traffic accident mortality rate in the areas where it is used has been reduced by more than 90%.

This product has successfully passed the collision test of small cars and large trucks at the highway test site of the Ministry of Transport. The test results have reached the technical standard of SB guardrail anti-collision level.

 

 

 

Planning concept of anti-collision guardrail:

According to the "Highway Traffic Safety Equipment Planning Standards" (JTG D81-2006), the guardrail is defined as (Article 2.0.1). As a longitudinal energy-absorbing structure, the guardrail absorbs collision energy through self-deformation or vehicle climbing. Then change the direction of travel of the vehicle, prevent the vehicle from crossing the road or entering the opposite lane, and minimize the damage to the occupants. Under the set impact conditions, the guardrail should have the following functions:

 

1) Prevent vehicles from crossing the road or crossing the central divider into the opposite lane;

 

2) Prevent vehicles from getting out from under the guardrail or breaking the guardrail;

 

3) The guardrail should be able to return the vehicle to its normal direction of travel;

 

4) In the event of a collision, the damage to passengers will be minimal;

 

5) Can induce the driver's vision.

 

 

 

 

 

The functions of rotating anti-collision guardrail:

 

 

When a car is about to collide and rush towards the guardrail, due to the rotation of the roller, the impact energy of the car is converted into rotational energy parallel to the guardrail, achieving the effect of overcoming rigidity with softness. As a longitudinal energy-absorbing structure, the rotating anti-collision wave guardrail absorbs collision energy through self-deformation or vehicle climbing, thereby changing the vehicle's driving direction and preventing the vehicle from crossing the road or entering the opposite lane. This will minimize the damage to the occupants. It is particularly prominent in preventing vehicles from crossing the road or crossing the central divider into the opposite lane, and preventing vehicles from getting out from under the guardrail. In the event of a collision, the degree of damage to passengers will be greatly reduced.

 

 

 

 

 

Functions of rotating guardrail components:

 

1. Column: driven into the roadbed, it is the main stress-bearing component.

 

2. Cross beam: used to connect the columns and fix the rotating barrel.

 

3. Rotating barrel: It is fixed between the upper and lower beams and can rotate around the column. The main materials are EVA (ethylene-ester acid copolymer) and polyurethane.

 

4. Bushing: installed on the inner wall of the rotating barrel, a contact component for the rotating function.

 

5. Gyratory circle: Installed between the rotating barrel and the beam to balance and promote rotation.

 

6. Connecting frame: used for connecting between beams.

 

7. U-shaped frame: connects beams and columns and is used to fix beams.

 

8. Pad buckle: lined with cross beams and connected to the U-shaped frame.

 

9. Hoop: connects beams and columns, used to fix beams, suitable for specific types.

 

10. Reflective strip: It is a reflective film, which is pasted on the rotating barrel and plays a guiding role.

 

 

 

 

 

 

 

 

 

 

 

 

Installation method of rotating anti-collision guardrail:

 

 

1. When installing the rotating anti-collision guardrail, it is spliced to each other through splicing bolts and fixed to the columns or beams by connecting bolts. The splicing direction of corrugated beams is the key to installation. During construction, ensure that the overlapping direction should be consistent with the driving direction.

 

2. The rotating anti-collision guardrail should be continuously adjusted during the installation process, so the connecting bolts and splicing bolts should not be tightened prematurely so that the long round holes of the corrugated beam can be used for timely adjustment during the installation process. This will allow it to form a smooth linear shape, thereby avoiding local unevenness.

 

3. When installing, the top surface of the rotating anti-collision guardrail should be coordinated with the vertical curve of the road. And check the linear shape of the guardrail. When it is determined that the linear shape is relatively straight and smooth, the bolts can be tightened finally.
