Abstract

A novel high strength composite manhole cover relates to covers of inspection manholes of various pipelines in the urban construction municipal engineering. The utility model is characterized in that the novel high strength composite manhole cover is provided with a round or square manhole cover, of which the upper top is a plane surface, the lower bottom is an arc-shaped convex surface, the manhole cover can be assembled in coincidence with a seat ring 7 of the manhole and is composed of a top surface layer 4, an outer shell body 1 and an inner core body 2, wherein the surface layer 4 is an antiwear layer of which the top surface layer is formed in the way that resin and emery are compounded. The shell body which coats the core body of the manhole cover is a composite layer which is formed from the resin and a plurality of layers of glass fiber fabrics 6. The core body is a composite body which is formed from the resin, glass fiber bundles and inorganic aggregates. The utility model has the advantages that two layers of multi-strand glass fiber strands are laid in the core body to reinforce, a glass steel shell body is formed from the glass fiber fabrics and the resin to coat the core body, the antiwear layer is formed from the resin and the emery, a new technology that the solidification is carried out after moulding is adopted, therefore the product has the advantages of high hardness, high strength, corrosion, ageing resistance and long service life. The complete inorganic composite material is adopted, and the returned value is zero, and the manhole cover is thoroughly prevented from being stolen.

Description

The ancient power lid of novel high-strength composite material

Technical field: the utility model relates to the manhole well lid of the various pipelines of urban construction municipal engineering.

Background technology: in the prior art, the manhole well lid of various pipelines such as urban construction sewage, tap water, telecommunications, combustion gas, traditional casting iron well lid is arranged, easily stolen stolen because of it, just invent the composite drain cover that recovery value occurred not having substantially in recent years, a kind of is reinforced concrete well lid, and it is still easily stolen that its defective is that reinforcing bar has been used many, with having lacked then insufficient strength, fragility is big; Two kinds is the glass fibre cement well lid, its no recovery value, but intensity is low excessively, and very fast meeting is crushed by automobile; Three kinds is polymer glass fiber and lid, and its greatest drawback is that layer structure is reasonable inadequately, and what particularly use as the glass fiber of strength bar is generally to work out cloth, and humidification is limited, so this well lid does not still reach hardness and requirement of strength.

Summary of the invention

The present invention is directed to the deficiency of prior art,, provide a kind of recovery value of both not had, make performances such as its abrasion resistance, hardness, intensity reach the ancient power lid of novel high-strength composite material of casting iron well lid technical standard substantially again for overcoming the defective of prior art.

For reaching the technical measures that above-mentioned purpose takes be, the ancient power lid of novel high-strength composite material, having upward, the top is the plane, go to the bottom to arc convex, equipped circle or square well lid can match with the seat ring 7 of well, constitute the wearing layer that surface layer 4 is composited by resin and diamond dust and quartz sand for ancient power hd top face one deck by surface layer 4, housing 1 and core body 2; Wrap up in the composite bed of housing 1 that applies end face on the ancient power cover core body, following convex surface and periphery thereof for constituting by resin and multilayer woven glass fabric 6; The complex of core body 2 in the housing for constituting by resin and glass fiber bundle and inorganic aggregates.

Its preferred version is that the multiply cordage of the glass fiber bundle of described formation core body for being made by long glass fibres taked two layers of groined type or radial layings; The inorganic aggregates of described formation core body is a quartz sand, perhaps, and the mixed sand of quartz sand and diamond dust.

Advantage of the present utility model is, laying two layers of multiply glass cord in the core body strengthens, constitute glass steel shell by multilayer woven glass fabric and resin and wrap up in deposited core body, constitute wear-resistant coat by resin and diamond dust, and adopt mold pressing, solidification process, product hardness height, intensity is big, corrosion-resistant, anti-aging, the life-span is long.Adopt the full-inorganic composite material not have recovery value, prevented that thoroughly well lid is stolen.

The specific embodiment: shown in accompanying drawing 1 the utility model sectional view and accompanying drawing 2A-A sectional view, it is a round manhole cover embodiment, end face is that plane, bottom surface are arc convex, overlook rounded well lid on its profile, seat ring 7 shown in it and the accompanying drawing 4,5 can coincide equipped, and well lid is made of surface layer 4, housing 1 and core body 2.The wearing layer that top surface layer 4 is composited by resin and diamond dust for ancient power hd top face one deck, see shown in the accompanying drawing 3 (partial enlarged drawing I), the composite bed of housing 1 for constituting by resin and multilayer woven glass fabric 6, it is wrapped up in core body and applies, present embodiment adopts triplex glass cloth and resin to constitute, see shown in the accompanying drawing 3, the complex that core body 2 is made of resin and glass fiber bundle and inorganic aggregates, glass fiber bundle is meant the multiply cordage of being made by long glass fibres, groined type or radial laying, present embodiment adopts groined type to lay two layers, described inorganic aggregates is a quartz sand, perhaps, the mixed sand of quartz sand and diamond dust, present embodiment is the mixed stone sand of quartz sand and diamond dust.

This Gu power lid adopts mold pressing, curing process is made, increased density, hardness and intensity, below further specify the structural feature of the utility model by the manufacture craft order: make prior to counterdie and cover the end and peripheral housing 1, with the 6 alternate layings from level to level of triplex glass cloth with resin, press groined type afterwards and lay one deck multiply glass cord 3, pour resin and quartz sand into, the compound of diamond dust, and then laying one deck multiply glass cord, finish the stone of core body 2, make upper shell 1 afterwards, at last with resin and diamond dust and quartz sand, and the mixture of inorganic dyestuff is poured on it and to be made wear-resistant coat 4 (dosing not homochromy dyestuff by required), simultaneously pre-buried well lid is opened nut 5, carries out mold pressing then, keep, solidify and the demoulding.The described resin of the application is a unsaturated polyester resin, need add the uses of initator and accelerator, and described diamond dust is carborundum.This well lid lifts unlatching with bolt.Accompanying drawing 4,5 and partial enlarged drawing II (being accompanying drawing 6) have shown the structure of seat ring 7, comprise housing 1 ', core body 2 ' and have multiply reinforcing glass cordage 3 '.

This well lid also can be directly by on the seat rings such as cast iron that are put into stolen well lid.Can produce the road castor etc. that leaks by above-mentioned building method.
