来源:http://www.zgcjxdw.com添加时间:2021-01-12 15:46:00

井盖现在市面上很多,各种各样都有,按材质区分,可分为金属井盖:铸铁、球墨祷铁、青铜井盖等随着检查井技术应用的不断提高,它的种类和款式也呈现多样性。每个区域在选择上都有相应的型号和种类。对于检查井来说更不可缺少的就是井盖了。一旦井盖出现问题,许多问题也就随之而来。因此,选择合适的井盖是非常重要的。

There are many kinds of manhole covers on the market. According to the material, they can be divided into metal manhole covers: cast iron, ductile iron, bronze manhole covers, etc. with the continuous improvement of the application of manhole technology, its types and styles are also diversified. Each area has its own model and type. For the inspection well, the most indispensable is the well cover. Once the well cover has problems, many problems will follow. Therefore, it is very important to choose the right well cover.

每种检查井的尺寸不同,它所对应的井盖尺寸也不同。在选择井盖时可根据我国《检查井井盖》标准去选择。比如:塑料检查井的标准尺寸为700时(一般都为井口尺寸),井盖则应选择750以上的尺寸。这也就是说当我们在选择井盖时,它的实际尺寸要比井口的尺寸大50mm左右。

The size of each inspection well is different, and its corresponding well cover size is also different. The selection of manhole cover can be made according to the standard of "manhole cover" in China. For example, when the standard size of plastic inspection well is 700 (generally wellhead size), the size of well cover should be more than 750. That is to say, when we choose the manhole cover, its actual size is about 50 mm larger than the wellhead size.
