Abstract

Disclosed is a composite well lid, which takes the compound of the concrete or the resin and the sand (stone) as the core body, and a shell body is formed by enwrapping the outer surface of the core body with the fiberglass reinforced material, the upper surface of the shell body is spread with a wear resistant layer made of resin and sand (stone). The utility model is characterized by high intensity, wear resistance and corrosion resistance, and has good bearing performance, low production cost, no returned value and easy promotion and application.

Description

Composite drain cover

What the utility model was related is a kind of composite drain cover, and it is to be composited by multiple material.

At present, on the road in China city, residential district etc., use a large amount of well lids, its well lid is cylinder iron made mostly, and the well lid of being made by cast iron mainly exists easily and gets rusty, breaks and by shortcomings such as pilferages.The ductile iron well lid with lock that development in recent years is got up has solved splintering problem, get rusty and stolen problem but can not solve at all, and cost is very high.

In order to solve the stolen and high problem of cost of casting iron well lid, researchers adopt glass-reinforced plastic material to make well lid, and drop into and try out, and this well lid does not have family's use value and industrial recovery value, has fundamentally solved the stolen problem of well lid.From applicable cases, that glass fibre reinforced plastic manhole covers has is corrosion-resistant, anti-ly steal, save advantages such as metal material, and upper surface is not wear-resisting, the more high deficiency of cost of production but exist yet, have in addition do not reach load bearing requirements.Thereby also there are many problems in glass fibre reinforced plastic manhole covers in actual applying.

The purpose of this utility model is exactly a kind of load bearing requirements that both reached of problem design that exists at existing well lid, and is wear-resisting again, antitheft and production technology is simple, a kind of composite drain cover of low production cost.

The utility model is described in further detail below in conjunction with drawings and Examples:

Accompanying drawing is a sectional view of the present utility model.

Be a kind of composite drain cover of the present utility model as shown in drawings, mainly comprise the core body of forming by concrete or sand (stone) and unsaturated polyester resin [1], the shell body [2] that glass fiber reinforced plastics is formed, the wearing layer [3] of high-abrasive material composition.

Implement one

Select for use cement, cobble, sand (stone), water etc. to mix and pour Mold Making core body [1] into, and through maintenance 15 days, the demoulding was standby with proper proportion.

Make reinforcing material with middle alkali plain, soak into 191 unsaturated polyester resins after, the appearance that is coated on core body [1] is to form the shell body of being made by glass fiber reinforced plastics [2].

Wearing layer [3] is formed (adding small amount of fibers in case of necessity) by quartz sand, 191 unsaturated polyester resins, is coated on the upper surface of shell body [2], and covers to be shaped the demoulding after 48 hours with mould.The composite drain cover made from the method can carry 21000kg.

Implement two

Select for use quartz sand, unsaturated polyester resin (adding a small amount of glass fiber in case of necessity) to mix, pour mould into, make core body [1], the demoulding is standby after 6 hours.

Select for use the alkali-free plain to make reinforcing material, soak into 191 unsaturated polyester resins after, the appearance that is coated on core body [1] is to form the shell body of being made by glass fiber reinforced plastics [2].

Wearing layer [3] mixes a small amount of glass fiber by quartz sand, marble particle, 191 unsaturated polyester resins, mixes, and is coated on the upper surface of shell body [2], and thickness is no less than 5mm, and covers to be shaped the demoulding after 48 hours with mould.The composite drain cover made from the method can carry 40000kg.

Claims

1. composite drain cover is characterized in that: described composite drain cover by core body [1], be coated on the shell body [2] of core body [1] appearance and be coated with the wearing layer [3] that is layered on shell body [2] upper surface and form.

2. composite drain cover according to claim 1 is characterized in that: core body [1] is made up of concrete or is mixed to solidify with sand (stone) by resin and forms.

3. composite drain cover according to claim 1 is characterized in that: shell body [3] is made up of glass fiber reinforced plastics or glass fiber reinforced cement.

4. composite drain cover according to claim 1 is characterized in that: wearing layer [3] is mixed with sand (stone) to solidify by resin and forms or be made up of glass fiber reinforced plastics.
