What are the correct operating steps for synchronous sealing trucks?
Release Time:2023-09-15
In modern highway construction, the synchronous sealing truck has become an important construction equipment. It provides strong support for highway construction with its efficient and precise working performance. When gravel appears on the asphalt road, it affects the driving of vehicles and is potentially dangerous. At this time we will use the synchronous sealing trucks to repair the road surface.

First, let’s understand how the synchronous sealing truck works. The synchronous gravel sealing truck is a construction equipment with a high degree of automation. It is controlled by a computer to achieve precise control of the vehicle's speed, direction, and loading capacity. During the construction process, the vehicle will evenly spread the pre-mixed gravel on the road surface, and then compact it through advanced compaction equipment to perfectly combine the gravel with the road surface to form a solid road surface.

In highway construction, synchronous gravel sealing trucks have many applications. For example, it can be used to repair damaged parts of the road and improve the load-bearing capacity of the road; it can also be used to lay new pavement to improve the traffic efficiency of the road; it can also be used to fill the roadbed to enhance the stability of the road. In addition, the synchronous gravel sealing truck also has the advantages of short construction period and low cost, so it is favored by the majority of highway builders.

Specifically how to operate the synchronous sealing truck correctly, our company will share with you the correct operating steps of the synchronous sealing truck:
1. Before operation, all parts of the car should be checked: valves, nozzles and other working devices of the pipeline system. They can be used normally only if there are no faults.
2. After checking that the synchronous sealing vehicle is faultless, drive the vehicle under the filling pipe. First, put all valves in the closed position, open the small filling cap on the top of the tank, and put the filling pipe into the tank. The body begins to add asphalt, and after filling, close the small filling cap. The asphalt to be filled must meet the temperature requirements and cannot be too full.
3. After the synchronous sealing truck is filled with asphalt and gravel, it starts slowly and drives to the construction site at medium speed. No one is allowed to stand on each platform during transportation. The power take-off must be switched off. It is forbidden to use the burner while driving and all valves are closed.
4. After being transported to the construction site, if the temperature of the asphalt in the synchronous sealing tank does not meet the spraying requirements. The asphalt must be heated, and the asphalt pump can be turned during the heating process to make the temperature rise evenly.
5. After the asphalt in the box reaches the spraying requirements, load the synchronous sealing truck into the rear nozzle and stabilize it at about 1.5~2 m from the starting point of the operation. According to the construction requirements, if you can choose between front-controlled automatic spraying and rear-controlled manual spraying, the middle platform prohibits station people from driving at a certain speed and stepping on the accelerator.
6. When the synchronized sealing truck operation is completed or the construction site is changed midway, the filter, asphalt pump, pipes and nozzles must be cleaned.
7. The last train of the day is cleaned, and the closing operation must be completed after the operation.
8. The synchronous sealing truck must drain all the remaining asphalt in the tank.

In general, the synchronous gravel sealing truck provides strong support for highway construction with its efficient and precise working performance. With the development of science and technology, we have reason to believe that synchronous gravel sealing trucks will play a greater role in future highway construction.
