Recently, when some citizens passed through Shuicheng Road, they found that the road surface became black and glowing, thinking that it was using high-tech materials, and when they looked closer, they found that the original paving steel plate was flatly embedded in the ground. What's going on here, let's take a look.
Paving steel plates are not unfamiliar to citizens, and sometimes they are often encountered on the road. Municipal road construction usually lays a section of steel plate on the road surface repair section and sets a speed bump around it to ensure the normal passage of vehicles. This practice has always been the traditional practice of municipal construction, and it is the same in all districts.
Not long ago, yongda municipal company in the construction process with a duty traffic police to learn that the temporary laying of steel plates and the surrounding speed bump construction method, municipal traffic and citizens travel has a certain impact and safety hazards. Specifically, when a vehicle drives to the construction section, it must slow down or detour to avoid, if the speed is too fast, there will be a safety hazard. However, during peak hours, slowing down will cause traffic congestion, and the vehicle will produce greater noise when driving through the speed bump, which will have an impact on the lives of surrounding residents.
It was this dialogue that attracted the attention of Yongda Municipal Corporation, and coincided with its long-term desire to develop embedded paving steel plate technology. Therefore, a pilot renovation project was carried out in the section of Shuicheng Road in Xianxia Xincun Street.
△ Municipal traditional laying of steel plates
Today (November 15) morning, the reporter saw on Shuicheng Road that a layer of steel plates was laid on the road section. Unlike in the past, this time, the paving steel plate is tightly embedded in the ground, as if it is integrated with the road surface. When the vehicle passes through this section, there is no need to slow down, slow down and avoid, and the load bearing is also consistent with the ordinary road surface, and the bus driving through does not have a great impact.
"This set of construction techniques looks like it just dug a groove and embedded the steel plate into it. In fact, the construction technology requirements are very high, and it is definitely a set of 'fine work'."
According to Jiang Yi, the person in charge of the project, the embedded construction of the steel plate must first measure the size repeatedly, and then wash the grooves on the road surface, and then embed the steel plate after the grooves are washed to a certain extent, and then pad the surrounding into the sack to increase the degree of tightness to achieve cushioning, shock absorption, and increase friction and resistance. In the process, the groove is required to be consistent with the thickness of the steel plate, and in order to achieve a fine effect, the machine needs to manually repair the groove after washing to a certain extent.
"During construction, in order to pursue the effect of leveling with the road surface, it is not only necessary to repeatedly measure the data to ensure that the size of the steel plate is consistent with the size of the groove, but also to ensure the flatness with the road surface after continuous attempts." It is often the steel plate covered and then hung up, so repeated adjustment, until the steel plate embedded groove is no different from the road surface and will not cause the road surface to collapse. ”
After continuous attempts and adjustments by Jiang Yi and the construction team, the steel plate was finally embedded in the grooves.
"The road surface is very flat, every day from here, usually how to ride now how to ride, do not need to slow down." "In the past, the speed bump on the road was a little higher, and sometimes when I passed, I was afraid of falling, so I had to pay special attention to slowing down or going around, but this time I didn't need it, and I was much more down-to-earth." The citizens who came and went responded well to the road surface, and said that there was not much difference from the normal road surface, and the safety factor was much higher than in the past when passing, just like walking on the ground.

According to the relevant person in charge of Yongda Municipal Company, the technical research and development of embedded paving steel plates is a bold attempt, which is the first time in the whole region and is a "precedent".
At present, Yongda Municipal Company has included the construction of embedded steel plates in the "I do practical things for the masses" project, first taking Shuicheng Road as a pilot, carrying out the first trial, and will be promoted throughout the district after the technology is mature. At that time, residents' travel will be more secure.
