The Case of Composite Manhole Cover in Hangzhou

Author: Site Editor     Publish Time: 2022-05-20      Origin: Site

The manhole cover in the Chengzhong Street, Lin'an District, Hangzhou City, Zhejiang Province has a problem as the cast iron manhole cover will settle with long-term vehicle crush. Anytime cars drives over the manhole cover, it seems that they are driving through a "small pothole". It could cause big noise and serious safety hazards.

Finally, Lin'an government decided to upgrade the cast iron manhole cover to solve this problem. After investigation, the government chose the composite manhole cover of JINMENG.


  • JM-MR114D-F Composite Manhole Cover, the first domestic anti-settling manhole cover independently developed by JINMENG, changes the connection between the manhole cover and the well ring and combines the well ring with the road as a whole. It helps change the stress condition of the well ring, and the widened base can effectively buffer the impact from the passing vehicles. Nearly 80% of the vehicle load is absorbed by the road through the well ring, making the manhole cover "float" on the road surface to avoid settlement.


  • At the same time, the composite manhole cover features sealing rubber strip and smaller gap than the cast iron manhole cove, making the manhole cover fit better and effectively absorb vibration to reduce noise.

The upgraded anti-settling manhole cover is a good solution to the problem of manhole cover in Lin'an’s city management as it upgrades the function of manhole cover. Quality manhole covers not only help Hangzhou city construction but also witness the improvement of urban management.

As the functionality of the manhole cover was perfected, the city administration begin to focus on aesthetic aspect of manhole cover. They seek for manufacturers of manhole covers and choose the right manhole cover, hoping that manhole covers can not only add icing on the cake but also to show the unique city culture of Hangzhou.


Traditional manhole covers can never be beautiful. So how to make this small cover stunning to show the city culture?



  • JINMENG is so innovative that it combines the aesthetic and cultural aspects of manhole covers. It has been committed to developing exquisite manhole covers with cultural meanings, which not only strengthens the beauty of manhole covers but also helps boost city culture display and transmission.



  • As a window of Hangzhou's cultural exchange, West Lake has always been attracted much attention. Manhole covers used in the scenic spot also become a beautiful landscape. To ensure the safety of pipeline transport, anti-static composite manhole covers are safer than cast iron manhole covers to avoid explosion.



  • By seeking for the representative elements of West Lake, JINMENG customized the manhole cover with the logo of Three Pools Mirroring the Moon for Hangzhou Natural Gas Company. The manhole cover aims to ensure safety and show the taste of Hangzhou City.
