Abstract
The utility model provides a high-strength composite material manhole cover. The utility model has a well base made of composite material; the well base is provide with a detecting hole; the well base is provided with a well cover made of composite material; the upper surface of the well cover is provided with a hard wearing layer; the polyvinyl alcohol is arranged inside the hard wearing layer. The utility model has the advantages of corrosion resistance, high intensity, high toughness, high hard wearing, light weight and so on.
Description
Technical field
The utility model relates to urban environmental protection equipment, is a kind of high strength composite manhole cover.
Background technology
The widely used manhole cover in the city, great majority are manufactured for cast iron, common magnesite material, glass fiber reinforced plastic or steel fibrous concrete.The deficiency that the well lid of these structures exists is: cast iron cover easy-to-rust, easily stolen and often have an accident; Common magnesite material intensity is low, not wear-resisting, not water-fast; Glass steel cover intensity is low, easily cracked; Steel fibrous concrete lid weight is big, intensity is little, bearing capacity difference etc.Because many deficiencies that these manhole covers exist cause manhole cover that problem often takes place, and directly influence the city normal order sometimes.
Summary of the invention
The purpose of this utility model provides a kind of high strength composite manhole cover, it have corrosion-resistant, intensity is high, toughness is high, abrasion resistance is high, advantage such as in light weight.
The utility model is achieved through the following technical solutions for achieving the above object: the high strength composite manhole cover, and it has composite well seat, offer inspection eye on the well seat, on the well seat composite drain cover is installed, the upper surface of well lid is provided with wearing layer, and vinal is arranged in the wearing layer.In the wearing layer that the upper surface of well lid is provided with quartz sand and anti-wear agent are arranged.Reinforcing rib is installed in the described well lid.Described reinforcing rib is the bamboo grid net.Described reinforcing rib is a steel mesh reinforcement.The upper surface of well seat is provided with wearing layer.Vinal is arranged in the wearing layer.
The utility model has following advantage after tested: corrosion-resistant, good waterproof performance, intensity height, toughness height, not cracky, abrasion resistance is strong, in light weight, bearing capacity is big etc.
Description of drawings
Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is plan structure schematic diagrames of accompanying drawing 1.
The specific embodiment
7 is well seats among the figure, offers inspection eye 8 on the well seat 7, and composite drain cover 5 is installed on the well seat 7, and the upper surface of well lid 5 is provided with wearing layer 2, and vinal 9 is arranged in the wearing layer 2.In the wearing layer 2 that the upper surface of well lid 5 is provided with quartz sand and anti-wear agent are arranged.In the described well lid 5 reinforcing rib 4 is installed.Described reinforcing rib 4 is bamboo grid nets 3.Described reinforcing rib 4 is steel mesh reinforcements 6.The upper surface of well seat 7 is provided with wearing layer 1.Vinal 9 is arranged in the wearing layer 1.The utility model can be made different shape and size as required.Bamboo grid net described in the utility model and steel mesh reinforcement all form with the composite material epoxy glue system of well seat, well lid, and bamboo grid net and steel mesh reinforcement are for installing and using respectively.The utility model also can be in the organic and inorganic material of well seat, well lid even dispersion polyethylene alcohol fibrous material, to increase its intensity.
