Abstract
The utility model relates to a super-thin polymer concrete well cover which belongs to the technical field of fixed construction. The utility model is characterized in that the thickness of a well cover is from 30 to 40 mm, the bar diameters of a bar mat in the well cover is from 3 to 6 mm, and the meshes of the bar mat is 20 to 40 mm*20 to 40 mm. the utility model has the used material of epoxy resin, cement, flyash, river sand, stones, nanometer converted material, organic short fibers, solidifying agents, diluents, plasticizers, toughening agents and coupling agents. The beneficial effect of the utility model is to obtain a cast-iron well cover substitution product with the incapability of being used as a target by robbers, thin thickness, high strength, high and low temperature prevention, corrosion resistance, carbonization prevention, durable use and low cost. After tests, the bearing capacity of the well cover is more than 350 KN which is equivalent to seven times the amount of that of a normal concrete well cover with an equal size, the produced well cover with 30 to 40 mm can satisfy the requirements of the use strength. The strength of the utility model is not obvious changed after freeze-thaw cycles for 1000 times, and the utility model is not changed after the utility model is immersed into an HCI solution of 1 mol/L and a solution of 5% NaOH for 5 months.
Description
Technical field
The utility model belongs to technical field of fixed buildings, is specifically related to a kind of Sewage well cover.
Background technology
The passage loam cake of existing Sewage well cover and other underground installation of city all adopts the cast iron manufacturing, in China, each urban sewage well lid was lost seriously in the last few years, not only because of changing the input that well lid has strengthened urban construction continually, and caused many injuries for vehicle, pedestrian.As continue to use casting iron well lid, can't resolve the problem of losing of well lid in the short time.Before this, ordinary concrete well lid and silicon plastic well lid once appearred.Because the intensity and the corrosion-resistant anti-aging problem of material therefor, not only volume is too thick and heavy, and application life is very short.
Summary of the invention
The purpose of this utility model provides a kind of thin polymer concrete manhole cover, overcomes existing casting iron well lid and easily loses, the shortcoming that ordinary concrete well lid and silicon plastic well lid are too thick and heavy, application life is short.
The utility model is by concrete manhole cover, and the steel mesh reinforcement in the concrete manhole cover is formed, and is characterized in that the thickness of well lid is 30-40mm, and the bar diameter of steel mesh reinforcement is 3-6mm in the well lid, and the mesh of steel mesh reinforcement is 20-40mm * 20-40mm.
The used material of the utility model well lid is epoxy resin 1 weight portion, cement 0.1-2 weight portion, flyash 0.1-2 weight portion, river sand 2-6 weight portion, stone 3-9 weight portion, nano modified material 0.01-0.1 weight portion, organic short fiber 0.001-0.02 weight portion, curing compound 0.05-0.15 weight portion, thinner 0.05-0.35 weight portion, plasticizing agent 005-0.4 weight portion, flexibilizer 0.005-0.2 weight portion, coupling agent 0.005-0.2 weight portion.Nano modified material wherein can be selected nano silicon, nano titanium oxide, nano-calcium carbonate for use.Organic short fiber can be selected the fine fiber of polypropylene, polyester fiber, polypropylene fibre for use.Curing compound can be selected amido curing compound, synthetic resin curing compound, acid anhydride type curing agent for use.Thinner can be selected acetone, toluene, isobutanol for use.Plasticizing agent can be selected phthalic acid ester, fat diacid two fat, tributyl phosphate for use.Flexibilizer can be selected nitrile rubber, polyester, polyamide for use.Coupling agent can be selected silane, titanate esters for use.
The manufacture method of the utility model well lid is: the material requested that will select for use by weight ratio mixes, form slurry stirs, in mould, put into steel mesh reinforcement, again slurry is poured in the mould, through precuring, the demoulding, maintenance, promptly get nona modified fiber reinforcement high-performance polymer concrete well cover of the present invention.
Good effect of the present utility model be obtain a kind of can stolen molecule as target, thin thickness, the intensity height, high-and low-temperature resistance, corrosion-resistant, the casting iron well lid substitute products durable, that cost is low are used in anti-carbonization.Through test, well lid bearing capacity of the present invention reaches more than the 350KN, is equivalent to 7 times of comparable size ordinary concrete well lid, makes the well lid of 30-40mm, can satisfy the working strength requirement.1000 intensity of freezing-thawing cycles do not have obvious change, immerse in the H1 solution of 1mol/L and 5 months no changes in the 5%NaOH solution.
Description of drawings
Accompanying drawing is the utility model overall structure schematic diagram.
The specific embodiment
Stone 3 weight portions about extracting epoxy resin 1 weight portion, cement 0.1 weight portion, flyash 0.1 weight portion, river sand 2 weight portions, particle diameter 10mm, nano silicon 0.01 weight portion, fine short fiber 0.001 weight portion of polypropylene, amido curing compound 0.05 weight portion, thinner acetone 0.05 weight portion, plasticizer phthalic acid ester 0.05 weight portion, flexibilizer nitrile rubber 0.005 weight portion, coupling agent silane 0.005 weight portion.With above-mentioned material mix, form slurry stirs; in mould, put into by φ 5 reinforcing bars and make the steel mesh reinforcement 2 that mesh is 30mm * 30mm; again slurry is poured in the mould; make the thick 30mm in edge; be arc surface above; the well lid 1 of center thickness 40mm, through with precuring, the demoulding, the maintenance of common concrete component the same terms, promptly get thin polymer concrete manhole cover of the present invention.
