Today, I invited a manhole cover manufacturer to analyze to my friends how to prevent the deformation of resin manhole covers. There are already many types of manhole covers on the market, but today I want to tell my friends that this one is made of curing agent, accelerator, etc. Made of auxiliary materials, it has the advantages of large bearing capacity and long service life. It is widely used, but it will not be deformed under long-term use and external force.

     1. When the groove of the resin manhole cover is narrow, it can be tamped manually or with a frog-type tamping machine. Different fillers and different filling thicknesses should use different tamping tools to obtain economical compaction.

     2. When backfilling the groove of the resin manhole cover, it is necessary to select the appropriate filler and compaction (tamping) machine according to the backfilling position and construction conditions.

     3. The silt, tree roots, turf and humus used for filling not only affect the compaction, but also shrink and rot in the soil to form holes. These materials cannot be used as fillers to avoid subsidence.

     Let’s summarize these three points for friends about the deformation. The deformation of this manhole cover is well known, so today’s summary of the prevention methods to prevent deformation is here. If you are very interested in today’s topic, you can pay attention to it. Kingmetal, of course, if you want to buy a batch of manhole covers, you can also contact us directly, or you can directly come to our company for on-site inspection.
