Abstract

The utility model discloses a high-strength well cover which relates to a sealing element for inlets and outlets of various underground installations, in particular to a cover board and a water grate for covering various underground pipeline inspection wellheads. The high-strength well cover comprises a surface layer, a middle layer and a skeleton layer, wherein the surface layer is made of a wear-resisting material, and the surface of the surface layer is slightly convex upwards; the skeleton layer is provided with a grid combination of transverse threaded steel and longitudinal threaded steel, polymer composite materials are filled among the threaded steels, and the lower surface of the skeleton layer is slightly convex downwards; and the middle layer is a reinforcing layer, is made of a high-strength polymer composite material and is provided with a plurality of reinforcing ribs, and the reinforcing ribs are made from high-strength resin materials; besides, the well cover disclosed by the utility model is also provided with opening holes which run through the well cover. The high-strength well cover has the beneficial effects that a grid structure that combines the transverse and the longitudinal threaded steels in a skeleton is a breakthrough for the traditional skeleton, and not only the bearing capability and the bending resistance capability of the well cover are greatly enhanced, but also the dead weight of the well cover is reduced.

Description

The high strength well lid

Technical field

The utility model relates to the closure of a kind of all kinds of underground installations access, relates in particular to a kind of cover plate, water grate that all kinds of underground pipelines are checked well head that be used to cover.

Background technology

The underground pipeline well lid of current urban operating mechanism and road always uses traditional cast iron manufacturing, has birth defects such as corrosion, not corrosion-resistant, frangible, heaviness.Because of its tool regeneration is worth, so the stolen repeatedly city trap that becomes brings great harm for public safety and people's lives and properties.For eliminating city hidden danger, various antitheft manhole covers arise at the historic moment, but most nonmetal manhole cover does not reach the universal standard because of thickness, and can not replace castiron well cover; In addition, manhole covers such as the steel fiber reinforced concrete manhole cover in the various nonmetal manhole cover of present public technology, regenerating resin manhole cover made of composite material, cement manhole cover, polymer composite manhole cover, resin base composite material manhole cover, plastics well lid, theftproof lock manhole cover, have mostly in various degree that bearing capacity is low, poor toughness, counter-bending scarce capacity, easy fracture, easily disintegrate, thickness is big, heavy, cost is high, easy defectives such as aging, life-span weak point, complex process, can not effect a radical cure the chronic disease of manhole cover, urban road hidden danger still.

Summary of the invention

Problem at above-mentioned prior art existence, the utility model purpose be to provide a kind of existing durable in use, corrosion-resistant, weatherability is high, the life-span is long, cost is low, do not have advantages such as theft value, again tool more high-bearing capacity, insert depth meet the universal standard can with environmental protection, the energy-saving high strength well lid of characteristics such as casting iron well lid exchange.

The technical solution of the utility model is: the high strength well lid, comprise surface layer, intermediate layer, casing play, and described surface layer is made up of high-abrasive material, and the surface is upwards protruding slightly; Described casing play has horizontal thread steel and the combination of longitudinal screw steel grating, and filled high polymer composite material between the screw-thread steel, casing play soffit are protruding slightly downwards; The intermediate layer is an enhancement Layer, adopts the high strength polymer composite, is provided with plurality of strengthening ribs, and reinforcing rib adopts the high-strength resin material to make.

Also have the open hole that runs through well lid on the described well lid of the present utility model.

The beneficial effects of the utility model are: the utility model grid structure that employing first laterally combines with the longitudinal screw steel in skeleton is the once breakthrough to traditional skeleton, not only strengthened the bearing capacity of well lid, counter-bending ability greatly, and the deadweight that has alleviated well lid.Particularly importantly, at the well lid bearing load that surpasses regulation because of vehicle, reach reasons such as destroying load and cause the well lid internal break after, well lid still do not disintegrate, not broken, still kept complete relatively, allow the vehicle that is passing through continue to advance and unlikely causing the accident.

Shown in the figure: 1, open hole, 2, reinforcing rib, 3, surface layer, 4, the intermediate layer, 5, the horizontal thread steel, 6, the longitudinal screw steel, 7, casing play.

The specific embodiment

Further the utility model is illustrated with the specific embodiment with reference to the accompanying drawings below:

Embodiment: as shown in Figure 1, the high strength well lid comprises surface layer (3), intermediate layer (4), casing play (7), and described surface layer (3) is made up of high-abrasive material, according to force analysis, and surface tension effects, the surface of surface layer is upwards protruding slightly; Described casing play (7) the inside is provided with horizontal thread steel (5) and forms with longitudinal screw steel (6) grid assembled arrangement, and filled high polymer composite material between the screw-thread steel, casing play (7) soffit are protruding slightly downwards; Intermediate layer (4) is an enhancement Layer, adopts the high strength polymer composite, is provided with plurality of strengthening ribs (2), and reinforcing rib (2) adopts the high-strength resin material to make.

Claims

1. high strength well lid, feature is to comprise surface layer, intermediate layer, casing play, and described surface layer is made up of high-abrasive material, and the surface is projection slightly upwards; Described casing play is provided with horizontal thread steel and the combination of longitudinal screw steel grating, and filled high polymer composite material between the screw-thread steel, casing play soffit are protruding slightly downwards; Described intermediate layer is provided with plurality of strengthening ribs, and reinforcing rib adopts the high-strength resin material.
