What Are The Technical Characteristics Of Compound Sewage Cover

{dede:global.cfg_gsname/} | Updated: 2020-04-10 06:15:00
The composite manhole cover has the following characteristics in technology:
The composite manhole cover is made of high polymer composite material, with steel bar as the main internal framework, and is produced by high temperature molding. Its strength can bear 50 tons of weight.
The sewage cover is light in weight, convenient for transportation and installation, and can greatly reduce labor intensity. The new resin well cover has a good anti-theft performance, because the synthetic resin material has no recycling value, effectively put an end to the emergence of "urban black hole".
Installation characteristics
compound sewage cover
With the continuous development of technology, manhole cover, as a common municipal and architectural material, has developed rapidly. Here are the installation precautions for the composite well cover:
1、 In order to keep the appearance of the cover beautiful and the surface pattern and handwriting clear, a thin sheet iron or wood board shall be used to cover the well cover during the construction of asphalt pavement. The black well cover can also be brushed with waste oil to prevent the asphalt from spraying on the well cover
2、 The inner diameter, length x width and square circle of the brick masonry of the well cover shall be determined according to the well cover size designed by the Design Institute, which can also be executed according to the corresponding standards. A concrete protection ring with a width of 40cm shall be cast around the well cover, and the maintenance period shall be more than 10 days
3、 When installing the well cover on the asphalt pavement, it is necessary to avoid the construction machinery directly rolling the well seat. During the integral casting of the pavement, a hole slightly larger than the well seat shall be reserved on the pavement and placed after the asphalt pavement is completed
4、 After the well base is poured or paved with asphalt by concrete, the compound sewage cover shall be opened and cleaned in time to avoid mortar or asphalt from pouring the inspection well cover and the base into one, so as not to affect the opening in the future
