First, in strict accordance with the design construction. Urban guardrail design according to the terrain is reasonable and reliable, construction must be in strict accordance with the design drawings. To ensure the accuracy of the construction, you can first designate the location of the marker in the center line, and then measured from both sides of the road to ensure the accuracy of the area, and then to accurately mark the location of the guardrail. Establishing guardrail grid In order to ensure the construction progress and reliability of the guardrail bracket, you can dig a not too shallow pit on both sides of the fence bracket on both sides of the road, and the guardrail can be connected to the ground with a line to ensure the reliability of the support.As we all know, the municipal road guardrail is mainly used on the road, so also known as highway guardrail, to protect the safety of pedestrians and vehicles driving. Therefore, in order to better protect the safety of pedestrians and vehicles, in the construction of urban road guardrail, should pay attention to what?City guardrail adopts hot-dip galvanized anti-corrosion treatment 1. The cost of other coatings is higher than that of hot-dip galvanized antirust coating. 2. Hot-dip galvanizing in urban or coastal areas can also be maintained for 20 years without maintenance. In suburban environment, it can keep more than 50 years of service life, which is more durable than ordinary paint. 3. The galvanized coating is metallurgically bonded to the steel and becomes part of the steel, making the durability of the hot-dip galvanized coating more reliable. 4. The metallurgical coating of hot-dip galvanizing is more resilient and can withstand damage caused by transportation and use. 5. The process protection of hot-dip galvanizing is more comprehensive, allowing every part to be galvanized. 6. Other coatings are more difficult to construct than hot-dip galvanizing and do not save time and labor. 7. Hot-dip galvanizing allows for some simple visual inspection or nondestructive coating thickness gauges, which is more convenient than other coatings. 8. In general, the hot-dip galvanizing process can be highly mechanized and can be tightly controlled in the factory. As a result, the initial cost of hot-dip galvanizing is lower than other methods. Municipal guardrail installation and use will actually affect the service life of the guardrail, reasonable installation can make the city guardrail work, today we will understand how to install municipal guardrail. 1. Municipal guardrail in the factory, only need to be installed according to the order requirements. Products only need to be delivered to the construction site after the steel lining part of the column into the base, and according to the requirements of the relevant departments assembly can be. 2. After completing the basic setting, the municipal guardrail must be connected one by one using special bolts. 3. In order to make the municipal guardrail resist the malicious movement of wind, the ground should be fixed together with the internal expansion bolts.
