井盖模具开展起先源自于中国高速公路、铁路建造业的疾速开展,为了避免车辆掉入两边边沟然后发明了此模具。
The development of manhole cover mold originated from the rapid development of China's highway and railway construction industry. In order to avoid vehicles falling into the side ditch on both sides, the mold was invented.

而随着中国乡村城市化以及城市路途的疾速开展,该模具的效果也从曾经的高速路途开展成了各种路途适用。
With the rapid development of China's rural urbanization and urban road, the effect of the mold has changed from high-speed road to various road applications.

用于城市路途不只能够避免人们平常出行掉入,更避免了废物的掉入然后使得边沟堵塞形成城市内涝。
It can not only prevent people from falling into the city, but also prevent the waste from falling into the city, and then make the side ditch blocked and form urban waterlogging.

井盖模具可以说是应运而生的,它广泛的应用于高速高铁、水利、堤坝、水库工程的必需品,是城市环保的重要产品之一。
It is widely used in high-speed rail, water conservancy, dam, reservoir engineering necessities, is one of the important products of urban environmental protection.
