Abstract
The present invention is well cover of nanometer modified fiber reinforced high performance polymer concrete, and belongs to the field of fixed building technology. The well cover is made of composite material comprising epoxy resin, cement, flyash, sand, crushed stone, nanometer modifying material, short organic fiber, curing agent, diluent, plasticizer, toughening agent and couplant, and has reinforcing bar mat. The present invention may be used to replace well cover of cast iron easy to be stolen, and has high strength, high weather resistance, high corrosion resistance, low cost and other advantages.
Description
Technical field
The invention belongs to technical field of fixed buildings, be 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 period of time.Before this, normal 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 work-ing life is very short.
Summary of the invention
The purpose of this invention is to provide a kind of nona modified fiber reinforcement high-performance polymer concrete well cover, overcome existing casting iron well lid and easily lose, the shortcoming that normal concrete well lid and silicon plastic well lid are too thick and heavy, work-ing life is short.
The usage ratio of employed mixing material of well lid of the present invention and material is:
Resins, epoxy 1 weight part, cement 0.1-2 weight part, flyash 0.1-2 weight part, river sand 2-6 weight part, stone 3-9 weight part, nano modified material 0.01-0.1 weight part, organic short fiber 0.001-0.02 weight part, solidifying agent 0.05-0.15 weight part, thinner 0.05-0.35 weight part, softening agent 005-0.4 weight part, toughner 0.005-0.2 weight part, coupling agent 0.005-0.2 weight part.And in well lid, be equipped with reinforcing mat.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, trevira, polypropylene fibre for use.Solidifying agent can be selected amido solidifying agent, synthetic resin solidifying agent, acid anhydride type curing agent for use.Thinner can be selected acetone, toluene, isopropylcarbinol for use.Softening agent can be selected phthalic ester, fat diacid two fat, tributyl phosphate for use.Toughner can be selected nitrile rubber, polyester, polyamide resin for use.Coupling agent can be selected silane, titanic acid ester for use.
The manufacture method of well lid of the present invention is: the material requested that will select for use by weight ratio mixes, form slurry stirs, in mould, put into reinforcing mat, 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.
Positively effect of the present invention 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 normal 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 HCl solution of 1mol/L and 5 months no changes in the 5%NaOH solution.
