Municipal roads in Jiangxi Province guardrail Spot direct pin Mr. Lai, Jingdezhen Isolation Bar (* * *)
I believe everyone knows the universality of municipal guardrails in application. It also plays a significant role in road safety and beautification. However, the more important thing is to ensure its safety, and the protective measures are also an important part, which requires good protection in installation.
Since some road guardrails are used outdoors, it is inevitable that there will be days of wind and rain, so corrosion or damage are relatively normal, and the service life may be shorter than that of indoor guardrails. Therefore, it is necessary to maintain the outdoor road guardrails.
The service life of road guardrails is determined by different materials. Generally, the service life of galvanized guardrails, aluminized guardrails, plastic coated guardrails after galvanizing guardrails and plastic coated guardrails ranges from five to ten years.
Now there are also highway guardrails, which are made of high-quality low-carbon steel wire Aluminium magnesium alloy It is woven and welded with silk, and has the characteristics of flexible assembly, strong and durable. The service life is also about eight years.
No matter what material the fence mesh is, it has a service life. If you want to extend its service life, you have to work hard on maintenance. You need to check the status of the fence mesh regularly, repair the damaged fence mesh in time, and paint and maintain it regularly.
Generally speaking, road guardrails of high quality can be used for at least 15 years. In order to reduce costs, some fence manufacturers produce barriers of poor quality, which often cannot be used for 3-5 years. Therefore, professional manufacturers should be selected when purchasing barriers, and products with poor quality should not be purchased cheaply.
The installation of road guardrails is relatively simple and can be roughly divided into the following steps
1. Road segregation PVC guardrail The series assembly has been carried out according to the order requirements before leaving the factory. After the product arrives at the construction site, it is only necessary to insert the steel lining part of each column into the stable base, and then insert the steel lining part of each column into the stable base door Linear extension deployment is required.
2. After the basic layout is completed, use special bolts to properly connect each section of PVC guardrail.
3. In order to improve the wind resistance and prevent malicious movement of the cypress fence, the stable base and the ground should be fixed on the ground with internal expansion bolts.
4. Reflector shall be fixed on the top of PVC guardrail according to user requirements.
5. The movable cast iron seat can be symmetrically locked by road studs or expansion screws.
In addition, attention should be paid to the selection of protective paint during installation, which can increase the service life of the guardrail.
