Abstract

A well cover comprises a cover body, and is characterized in that a ceramic layer is provided on the cover body; a resin and fiber mixed layer is provided under the ceramic layer; a layer of bonding resin is provided to bond the ceramic layer and the resin and fiber mixed layer between both layers; accordingly, a ceramic fiber composite plate is formed.

Description

A kind of well lid

Technical field

The utility model relates to sewer and underground pipeline ancillary facility, specifically is meant a kind of well lid.

Background technology

In recent years, the face of land well lid robbery accident of sewer and various underground pipelines occurs repeatedly in the city, and the lighter influences urban traffic and people's daily life, and weight person causes traffic accident and various contingency, causes very big infringement for people's the security of the lives and property.This is mainly because various faces of land well lid mainly is to be made by ferrous material, and ferrous material has certain recovery value, sells off so usually stolen as scrap iron by the lawless person.

For eliminating the usually stolen hidden danger of this well lid, people have found out various strategies, mainly contain two kinds of thinkings: the one, anti-theft device is set on well lid, though this has reduced the stolen risk of well lid to a certain extent, but also increased the management cost of administrative department simultaneously, and anti-theft device of long duration also can get rusty or damage, and increased difficulty and cost that administrative department opens well lid maintenance underground pipeline.

Another thinking is to replace the material of irony as well lid with recovery value not high reinforced concrete plate or resin concrete plate; but the intensity of this well lid and toughness are not enough; usually can increase the management cost and the difficulty of administrative department by pressure break or because of other reasons is damaged.

The utility model content

The utility model provides a kind of well lid, and its main purpose is to overcome that well lid of the prior art is easily stolen, insufficient strength, shortcoming that cost is high.

The utility model adopts following technical scheme: a kind of well lid, comprise lid, this lid is provided with ceramic layer, divides into resin-fiber mixed layer at this pottery, be provided with one deck between ceramic layer and resin-fiber mixed layer and be used for bonding the two binder resin, form the ceramic fibre composite plate.

The down all right how bonding one deck steel plate of described resin-fiber mixed layer is to improve security of products.

Described resin-fiber mixed layer comprises strengthens resin and the glass fiber that mixes mutually with this reinforcement resin.

Described resin-fiber mixed layer also can comprise strengthens resin and the carbon fiber that mixes mutually with this reinforcement resin.

Described resin-fiber mixed layer can also comprise strengthens resin and the glass fiber that mixes mutually with this reinforcement resin and the mixture of carbon fiber.

Described lid periphery also is provided with reinforced frame.

The ceramic layer of described lid is provided with at least one and colludes the hole.

Described lid is circle or ellipse or rectangle or arbitrary polygon.

Described whole lid is coated with one deck resin integument, to gain in strength with attractive in appearance.

By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage:, greatly reduce the cost of well lid and stolen risk owing to adopted price lower and not have pottery, glass fiber or the carbon fiber of recovery value be raw material; Owing to adopted the reinforcement resin to reinforce, make well lid have higher intensity again simultaneously, can satisfy the requirement of sewer or underground pipeline well lid intensity.

The specific embodiment

The specific embodiment one of the present utility model, with reference to Fig. 1, a kind of well lid, be used for sewer and various underground pipeline, comprise lid 10, this lid 10 comprises the ceramic layer 1 near the face of land, has resin-fiber mixed layer 3 at this ceramic layer 1, ceramic layer 1 and resin-fiber mixed layer 3 usefulness one deck binder resins 2 are bonding, and one deck resin integument 7 coats whole lid 10.Resin-fiber mixed layer 3 can be formed by strengthening the mixing of resin and glass fiber, and strengthening resin can be unsaturated-resin, can be that glass fiber strengthens the unsaturated-resin layer as resin-fiber mixed layer 3; Resin-fiber mixed layer 3 also can be to be formed by carbon fiber and reinforcement mixed with resin, as being carbon fiber reinforcement resin bed; Certainly, resin-fiber mixed layer also can be by strengthening resin and glass fiber, carbon fiber mixedly setting up jointly.Binder resin 2 can be an epobond epoxyn, certainly, also can be other suitable resin binders.

Resin-fiber mixed layer 3 is to produce like this, at first is coated with the last layer resin, and shop one deck fiber is coated with one deck resin again, shop one deck fiber, and so repeated multiple times forms firm resin-fiber mixed layer.

With reference to Fig. 2, be the vertical view of present embodiment, on ceramic layer 1, be provided with two and collude hole 6, one be can certainly be and hole or a plurality of hole of colluding colluded.

The specific embodiment two of the present utility model, with reference to Fig. 3, its basic structure is identical with embodiment one with principle, is with the main distinction of embodiment one: also bonding one deck steel plate 4 under resin-fiber mixed layer.

The specific embodiment three of the present utility model, with reference to Fig. 4, its basic structure is identical with embodiment one with principle, and be with the main distinction of embodiment one: the periphery at lid 10 also is provided with reinforced frame 5, and this reinforced frame can be a steel plate.

The specific embodiment four of the present utility model, with reference to Fig. 5, its basic principle is identical with embodiment one, is with the main distinction of embodiment one: lid 10 is rectangle structure.

Above-mentioned only is several specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, according to well lid field of employment and performance requirement also can be the intersection MULTILAYER COMPOSITE of pottery, cement, calcium silicate board, fiber, steel plate, resin, or different materials is compound.Allly utilize this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
