Abstract
The utility model discloses a nodular cast iron combined type inspection well cover, comprising an inspection well cover body. The inspection well cover body comprises a nodular cast iron frame and an unsaturated resin covering layer outside coated and fixed on the nodular cast iron frame; wherein, the nodular cast iron frame comprises a frame dick. A plurality of unsaturated resin filling holes are arranged on the frame disk; a vertical frame is fixedly arranged on the bottom surface of the frame disk; the vertical frame and the outer periphery of the frame disk form a fixed step as a whole body; reinforcing ribs are fixedly arranged on the bottom surface, which is corresponding to the inner side of the vertical frame, of the frame dick, and the frame disk, the vertical frame and the reinforcing ribs are integrally casted and molded to form the nodular cast iron frame. The inspection well cover has the advantages of good anti-theft performance and high compression-resistance and earthquake-resistance strength.
Description
Technical field
The utility model relates to a kind of inspection shaft lid, is meant that specifically a kind of ductile iron and resin carry out compound combined manhole cover.
Background technology
Tradition inspection shaft lid all is to adopt cast iron, is placed on the base that is fixed in the inspection shaft mouth.Base is an annular construction member, and its endoporus generally is that top is bigger, and the shoulder hole that the bottom is less makes and forms a step on the inwall, inspection shaft lid shape and thickness and the identical and matched in clearance in base endoporus top, and the inspection shaft lid places on the step of base inner wall.Because present shortage of raw materials, price is surging, and a lot of lawless persons have been stretched to the inspection shaft lid on the road with the evil backstage manipulator, makes the inspection shaft of traditional cast iron cover stolen incident and frequently takes place, and lead to many injury accidents thus.For tackling this type of stolen problem, various places are all adopted the inspection shaft lid method that substitutes cast iron with steel fiber reinforced concrete manhole top successively, and the value that reduces the inspection shaft lid allows the burglar lose interest, and reaches antitheft purpose.Existing steel fiber reinforced concrete manhole top generally comprises a belt framework of being made by band steel, in framework, be provided with into the reinforcing rib of many screw-thread steels formations of groined type distribution, the screw-thread steel two ends are welded on the framework, and fill remaining space with concrete screw-thread steel is wrapped in wherein fully.The steel fiber reinforced concrete manhole top of this structure can only be fit to and general urban road use because the employing concrete is filled, and its antidetonation anti-pressure ability is relatively low, and is difficult to satisfy the resistance to compression requirement of speedway or major urban arterial highway.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and the spheroidal graphite that a kind of theftproof performance is good, the resistance to compression shock strength is high combined manhole cover is provided.
For achieving the above object, the technical solution of the utility model is, include inspection shaft lid body, it is characterized in that: described inspection shaft lid body includes the ductile iron framework, the outer unsaturated-resin covering layer that is fixed on the ductile iron framework that coats, described ductile iron framework includes the framework dish, this framework dish is provided with a plurality of unsaturated-resin resin filler openings, and the bottom surface of this framework dish is set with stile, the whole fixedly step that forms of this stile and framework dish outward flange, described framework dish with respect to the bottom surface of stile inboard on be set with reinforcing rib, described framework dish, stile, the cast molding of being integral of reinforcing rib integral body forms the ductile iron framework.Originally be provided with resistance to compression and shock resistance that sufficient intensity is provided for the inspection shaft lid by the framework of ductile iron, be coated with unsaturated-resin resin filler opening at the framework of ductile iron and make whole inspection shaft lid seem, reduced coveting of lawless person unlike metal product.
As further improving and replenishing to such scheme, technical characterictic of the present utility model also includes and the adaptive base of inspection shaft lid body, this base includes the bedframe of ductile iron integral cast moulding, and the outer unsaturated-resin covering layer that is fixed on the bedframe that coats, described bedframe is provided with a plurality of unsaturated-resin filler openings.
Described reinforcing rib is groined type and arranges on the bottom surface of framework dish.This is provided with the stiffening effect of strengthening reinforcing rib.
The tectal color of unsaturated-resin on described inspection shaft lid body and the base and the solid colour on road surface.This is provided with the advantage of having utilized the more convenient adjustment of unsaturated-resin color, adjusts to consistent with the road surface by inspection shaft being covered body and the tectal color of the unsaturated-resin of base, makes the inspection shaft lid coordinate more with the road surface, and integral body is more attractive in appearance.
Advantage of the present utility model is:
(1), resistance to compression shock strength height, inspection shaft lid body frame and bedframe by ductile iron integral cast moulding cover resistance to compression and the shock resistance that sufficient intensity is provided for inspection shaft, make this inspection shaft lid satisfy speedway or major urban arterial highway requirement of strength to the inspection shaft lid, applied widely;
(2), good anti-theft effect, on the framework of ductile iron and base, be coated with unsaturated-resin resin filler opening and make that whole inspection shaft lid seems fully to have reduced coveting of lawless person unlike metal product.
(3), color is easy to adjust, accomplishes the harmony on inspection shaft lid and road surface, overall appearance.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
