Problems solved by technology

The steel fiber reinforced concrete manhole cover has high bearing strength, but the material itself is brittle and the impact resistance is not ideal, especially when the joint between the manhole cover and the road surface is uneven during construction, there may be corners or cracks from time to time

Embodiment Construction

[0033] The present invention is described in detail below in conjunction with accompanying drawing:

[0034] The glass fiber reinforced polymer composite well cover of the present invention includes an inner core aggregate layer 3 composed of aggregates and functional fillers, an outer reinforced structural layer 2 composed of unsaturated resin and glass fiber, and a wear-resistant layer 1; The reinforced structure layer 2 includes unsaturated polyester resin glue A and 3% to 15% glass fiber B in a weight ratio of 10% to 30%, and the inner core aggregate layer 3 includes 45% to 78% of aggregate C and 5%-20% filler D, wear-resistant layer 1 includes 3%-15% wear-resistant material E.

[0035] Manhole cover is made according to formula of the present invention, operating procedure:

[0036] 15% unsaturated resin glue A, 10% glass fiber B, 60% aggregate C, 12% filler D, 3% wear-resistant material E.

[0037] ① Unsaturated polyester resin glue A is a polymer formed by polycondens...

Abstract

This invention relates to glass fiber strengthening and thermosetting resin compound materials well cover, which comprises the following: inner core materials layer composed of materials and function stuff; outer strengthening structure layer formed by unsaturated resin and glass fiber; and antifriction layer. The outer strengthening structure layer comprises the following countered as weight proportion: unsaturated polyester resin glue liquid A for 10 úÑí½30 úÑ; glass fiber B for 3 úÑí½15 úÑ. The inner core materials layer comprises materials C for 45 úÑ-78 úÑ and stuff materials D for 5 úÑ-20 úÑ and anti-friction materials E for 3 úÑ-15 úÑ.

Description

technical field [0001] The invention relates to a well cover made of glass fiber reinforced thermosetting resin-based composite material, in particular to a well cover made of glass fiber reinforced and polyester resin cemented with quartz mortar. Background technique [0002] The manhole cover made of traditional materials is prone to rust under natural conditions, and it is easy to generate noise when vehicles pass by. Modern roads, especially expressways, have a large traffic flow and many heavy vehicles. Traditional manhole covers are also difficult to meet the requirements in terms of strength. Moreover, manhole covers laid on the road are often stolen, causing damage to pedestrians and vehicles. ACCIDENT. A few years ago, a steel fiber reinforced concrete manhole cover was developed. Its pressure bearing effect is much higher than that of the cast iron manhole cover of the same specification. It can meet the requirements of passing heavy vehicles. It does not produce ...
