What Are The Technical Characteristics Of Composite Manhole Cover

{dede:global.cfg_gsname/} | Updated: 2020-06-01 02:31:29
The composite manhole cover has the following technical characteristics:
The composite manhole cover is made of high-molecular composite material, and the main frame is made of steel bars. It is produced by high temperature molding.
The manhole cover is light in weight, convenient for transportation and installation, and can greatly reduce labor intensity. The new resin manhole cover has very good anti-theft performance, because the synthetic resin material has no recycling value, effectively preventing the emergence of "urban black holes".
The compound manhole cover has high precision and corrosion resistance. After high temperature molding production, it has good acid and alkali resistance and corrosion resistance, effectively extending the service life of the resin manhole cover.
With the continuous development of technology, the manhole cover has been rapidly developed as a common material for municipal and construction. Here are some precautions for the installation of composite manhole covers:
First, in order to maintain the beautiful appearance of the cover, and the surface patterns and handwritings are clear, the manhole cover should be covered with sheet iron or wooden boards during the construction of asphalt pavement.
Second, the masonry building of the manhole cover should be determined according to the size of the manhole cover designed by the design institute, its inner diameter or length X width, square circle, can also be implemented with reference to the standard, and a concrete protection ring with a width of 40cm is cast around the manhole cover for maintenance The period should be more than 10 days.
3.When installing a manhole cover on an asphalt pavement, care must be taken to avoid construction machinery directly rolling over the well seat.When the pavement is integrally cast, a hole slightly larger than the well seat should be reserved on the pavement and placed after the asphalt is paved.
Fourth, after the well is cast or asphalt is laid in concrete, the composite manhole cover should be opened and cleaned in time to avoid the mortar or asphalt from pouring the inspection well cover and the seat into one, so as not to affect the opening in the future.
