Polyethylene composite material Manhole Cover came out
These days, on the Makino Road, which is being built in the new district of Xinxiang City, a high-strength manhole cover made of polyethylene composite materials, waste plastics and industrial fly ash as raw materials, has been neatly arranged in Xinxiang City, Henan Province. In the laying of the tap water pipe. According to the paving workers, the plastic manhole cover has a high compressive strength. A 20-ton roller is rolled over from the manhole cover. The manhole cover is still intact and can completely replace the iron manhole cover.
The manhole cover of the drainage system on the urban roads for many years is a cast iron manhole cover. Although it has a sturdy and durable surface, there are also defects such as an excessive gap between the manhole cover and the manhole base, and misalignment between the cover bases. In particular, the manhole cover was stolen, causing serious hidden dangers to the traffic safety. Children fell into the well and there were no shortages of bicycle front wheels. People complained about this, but the relevant units have always been The failure to find a good solution has become a difficulty in the governance of the road.
In order to solve this problem, in 2002, Xinxiang City Water Supply Company Pipeline Equipment Product Factory introduced domestic advanced patented technology to produce a polyethylene composite manhole cover. It is based on waste plastics and industrial fly ash as the main raw material, and then plasticized, enhanced anti-aging and other special processing, with heat, cold, alkali, pressure, impact resistance, tight joints and other fine properties, Can be widely used in water supply, sewage, communications, electricity, gas and other municipal construction. In mid-April this year, the manhole covers began to appear on the streets of xinxin.
Xinxiang municipal construction industry insiders commented that this type of manhole cover makes [users feel at ease, the people feel at ease, and the thieves give up their hearts". It is not only used for the drainage wells on the roads, but also applied to water supply, sewage discharge, communications, cables, etc. on urban roads. Various surface wells.
