Carbon fibre composite damping well cover and manufacturing process thereof

Abstract

The invention relates to a carbon-fibre composite damping well cover and a manufacturing process thereof. A cover body provided by the invention comprises at least one layer on the upper and lower carbon cloths, multiple carbon-fibre composite rod strengthening rib layers are packaged in the carbon cloths, an epoxy mixing padding is filled in the strengthening ribs, and the edge of the cover body and a contacting part of a well base are provided with rubber washers. The carbon-fibre composite damping well cover provided by the invention except overcomes the shortages of the common well cover, and has the advantages of high intensity, good environment aging resistance, abrasion proof, creep resistance, good safety stability, long service life and the like; and the carbon-fibre composite damping well cover can effectively solve a well cover anti-theft problem. The carbon-fibre composite damping well cover provided by the invention meet daily life use, also can be widely used to road section which has large traffic stream quantity and high carrying capacity load such as airports and quay ports, and is suitable for regions which has severe environment such as moistness weather.

Description

technical field [0001] The invention belongs to the field of municipal pipeline construction engineering, and particularly relates to a carbon fiber composite shock-absorbing manhole cover and its manufacturing process. Areas with relatively harsh environments such as mouths and humid climates. Background technique [0002] For a long time, the inspection manhole covers used in municipal public facilities in my country are generally made of cast iron. The limitations of its materials, processing energy consumption, and environmental pollution have brought troubles to engineering, the environment, and energy. In particular, the problem of the loss of manhole covers has not been well resolved, which often leads to traffic and personal safety accidents, affects urban economic construction, and has a negative impact on the social environment. [0003] The currently used manhole covers are as follows: cast iron manhole covers, cement manhole covers, composite material manhole co...

AI Technical Summary

Problems solved by technology

[0002] For a long time, the inspection manhole covers used in municipal public facilities in our country are generally produced by cast iron. The limitations of its materials, processing energy consumption, and environmental pollution have caused serious problems for engineering, environment, energy troubles

In particular, the problem of the loss of manhole covers has not been well resolved, which often leads to transportation and personal safety accidents, affects urban economic construction, and has a negative impact on the social environment

Cast iron manhole covers are easy to be stolen and noisy, which affects the lives of residents; cement manhole covers are bulky and difficult to open, which brings inconvenience to construction and maintenance and has insufficient carrying capacity; recycled resin composite inspection manhole covers are used during use, especially when the temperature is high In the case of continuous rolling by vehicles, the manhole cover will creep, causing the middle part of the manhole cover to sink continuously, and even fall off, which will cause a great safety hazard

The use of manhole covers today has certain application limitations
