Embodiment Construction
[0011] The present invention will be described in more detail below in conjunction with the accompanying drawings.
[0012] A polymer network pipe well cover mainly includes a cover body 1, a cover base 2 and a sealing ring 3. The cover body 1 is arranged on the bearing platform of the cover base 2, and a sealing ring 3 is arranged between the cover base 2, The sealing performance between the cover body 1 and the cover seat 2 is improved, and the performance of the well cover is improved. It is characterized in that: the top surface of the cover body 1 is provided with an opening valve 4, an anti-skid pattern 5 and a marking area 6, and the opening valve 4 is provided with a sealing plug, the opening valve 4 facilitates the disassembly and assembly of the cover body 1, and can also prevent the gas in the underground pipeline from emerging from the opening valve 4. The anti-slip pattern 5 increases the friction force on the top surface of the cover body 1. It is used to identif...

The invention discloses a polymer net pipe manhole cover which comprises a cover body, a cover base and a seal ring, wherein the cover body is arranged on a bearing platform of the cover base, and the seal ring is arranged between the cover body and the cover base. The polymer net pipe manhole cover is characterized in that opening valves, skid-proof lines and a marking area are arranged on the top surface of the cover body, reinforced ribs are arranged on the back, and fastening nuts are arranged on the side surface; fastening bolts are arranged on the cover base and connected with the fastening nuts; and the cover body and the cover base adopt a polymer plastic and unsaturated polyester resin composite material. According to the polymer net pipe manhole cover, the seal ring is arranged between the cover body and the cover base, so that sealing performance between the cover body and the cover base is improved; the cover body and the cover base are connected through the fastening bolts and the fastening nuts, so that the stability of the cover body and the cover base is further improved; and besides, with the adoption of the polymer material, the probability of rusting is low, and the service life of the manhole cover is prolonged.
Description
technical field [0001] The invention relates to a manhole cover, in particular to a polymer network pipe manhole cover. Background technique [0002] With the development of urbanization, the demand for underground pipelines is increasing. From the earliest discharge of production and domestic sewage and ground rainwater, it has rapidly developed to today's water supply, heating, cables, communications and other fields. Most of the traditional network manhole covers are cast iron or prefabricated with reinforced concrete. The cast iron manhole covers are heavy, inconvenient to install, and easy to rust. Because the metal has recycling value, they are stolen by criminals; the prefabricated concrete manhole covers are brittle and fragile. Cracks lead to poor sealing, and the gas in the pipeline is easily discharged through the cracks, polluting the environment. Contents of the invention [0003] The purpose of the present invention is to provide a kind of polymer network pi...
