Problems solved by technology

Traditional road manhole covers include cast iron manhole covers, concrete manhole covers, plastic manhole covers, resin composite manhole covers, etc. Among them, cast iron manhole covers are easy to steal, concrete manhole covers are easy to peel off and break, plastic manhole covers are easy to deform and age, and resin compound manhole covers are easy to be brittle and cracked. The fibers used are glass fibers, because the glass fibers are brittle and easy to break under the action of a large impact

Embodiment 1

[0006] Embodiment one: take resin, polystyrene, styrene, tert-butyl fat, methyl ethyl ketone, coarse sand, cloth scrap as raw material to make water grate well cover. Take 100Kg of resin, 40Kg of polystyrene, 80Kg of styrene, 2.5Kg of tert-butyl fat, 1.5Kg of methyl ethyl ketone, 400Kg of coarse sand, and 25Kg of cloth scraps and divide them into blocks of appropriate size, then fully stir and mix the above materials, Then put the mixture in a special mold. When the mold is heated to 143°C and pressurized to 160T, heat and pressurize for 6-8 minutes to mold to obtain a water grate well cover.

Embodiment 2

[0007] Embodiment two: take resin, polystyrene, styrene, tert-butyl fat, methyl ethyl ketone, stone, cloth scrap as raw material to make road manhole cover. Take 100Kg of resin, 40Kg of polystyrene, 80Kg of styrene, 2.5Kg of tert-butyl fat, 1.5Kg of methyl ethyl ketone, 600Kg of stones, 25Kg of cloth scraps and divide them into blocks of appropriate size, then fully stir and mix the above materials, and then Put the mixture into a special mold, when the mold is heated to 143°C, pressurized to 160T, heated and pressurized for 6-8 minutes, the road manhole cover is molded.

[0008] In the present invention, fabric scraps of unlimited materials are blended with resin, coarse sand, stones or coarse sand, and an appropriate curing agent is added. Under a specific pressure and temperature environment, different specifications of road grate manhole covers or manhole covers are produced with molds of corresponding specifications. The road inspection well cover, meanwhile, the steel fr...

Abstract

The invention relates to a new type of road well cover, in particular, the road well cover is manufactured by blending cloth fiber and resin and pressing through a mold under the action of a curing agent, so as to achieve the functions of resource reuse and toughness enhancement. It belongs to new road building material technology. That is, use resin, polystyrene, styrene, tert-butyl fat, methyl ethyl ketone, sand and gravel, and cloth scraps with a weight ratio of 1:0.4:0.8:0.025:0.015:4—6:0.25 for initial mixing and then heat at 143°C 1. Place it in a mold with a steel frame transfer frame under a pressure environment of 160T for 6-8 minutes to remove the mold, and make a resin fiber water grate well cover or a resin fiber road inspection well cover. In the present invention, the fiber of the fabric leftovers is used to greatly enhance the impact resistance effect of the manhole cover and improve the bearing capacity. The invention has the advantages of shock absorption and noise reduction, corrosion resistance and insulation, wear resistance and weather resistance, light weight and low price.

Description

technical field [0001] The invention relates to a new type of road manhole cover, in particular, the road manhole cover is manufactured by blending cloth fiber and resin and pressing through a mold under the action of a curing agent, so as to achieve the functions of resource reuse and toughness enhancement. It belongs to new road building material technology. Background technique [0002] Along with the continuous construction and development of urban roads, the inspection manhole covers and drainage manhole covers of various underground facilities under the roads are increasing rapidly. Traditional road manhole covers include cast iron manhole covers, concrete manhole covers, plastic manhole covers, resin composite manhole covers, etc. Among them, cast iron manhole covers are easy to steal, concrete manhole covers are easy to peel off and break, plastic manhole covers are easy to deform and age, and resin manhole covers are easy to be brittle and cracked. The fiber used i...
