Well covers are very common in our daily life。 Basically, they can be seen everywhere when we go out。 But although you often see it, how much do you understand about the well cover? For example, what is the cap size specification? Can you understand some of these questions? Speaking of this, maybe many people have no answer。 Now, Shandong Ductile Iron Well Cover Factory will improve it for you。
1. What are the specifications for the size of the well cover?
In fact, according to the current application situation, in fact, the size of the well cap is a variety of types, not a single one. In general, 600MM, 700MM and 800MM are comparatively common, and they are also used a lot. But the most commonly used type is 600MM. But there are also some in the 550MM or so, the utilization rate is also comparatively high. However, regardless of the size specification, the selection request is based on the load-bearing and application environment to make the choice, so not every time when using the well cover is arbitrary stop selection.
2. The choice of cap size is actually determined in many aspects.
On the one hand, the state has very strict requests for the use of well covers。 There are several different types of covers, such as single-layer, composite and cast iron, in the selection of types。 The strength and load-bearing of each type in operation will have certain differences。 However, according to the relevant rules, there are strict requests for the type of well cover to be chosen in the time of selecting the well cover。 For example, the type of well cover chosen by the greenbelt and the sidewalk in the time of using the well cover is different。 The main reason is that the people in and out of the central government are quite different, and there are also some other reasons。 Whether there is a vehicle passing or not, the traffic flow is different, so it is not uncommon that there are differences in the selection of well caps。
On the other hand, there are different standards for cap size in China or Japan. In China, there will be special regulations to stop the rules for the size specifications and application requests of the covers. In Japan, the covers they use are also regular, regardless of size or data, but they are different from the requests of China. So the specifications for the size selection or application of well covers are often quite different in different paradises. It cannot be unified.
