Abstract
A well lid preventing rushing floating, falling and being stolen and resistant to aging is characterized in that the whole well lid is of a cylindrical structure, an upper cover plate (6) is arranged on the upper portion of the cylindrical structure, a lower closure plate (8) is arranged on the bottom of the cylindrical structure, the upper cover plate (6) is provided with upper flow guidance holes (1), and the lower closure plate (8) is provided with lower flow guidance holes (5). The well lid preventing rushing floating, falling and being stolen and resistant to aging is quite easy to clean and can be cleaned just by uncovering the well lid, and has the functions of preventing rushing floating, falling and being stolen and resistant to aging.
Description
Technical field
The utility model relates to into the lid technical field, and especially a kind of erosion control is floating, fall arrest, antitheft, anti-aging well lid.
Background technology
Existingly advance the covering plate structure that lid is generally cast iron, easily be corroded, aging, use in the place of hypsography low-lying, easily produce ponding, the stasis of blood is stifled, to cleaning, has brought inconvenience.In addition, it is larger that tradition is advanced the lid deadweight, easily produces and subside, and falls, and to traffic safety, brings very big hidden danger, also very easily stolen.
Summary of the invention
The purpose of this utility model is to provide that a kind of erosion control is floating, fall arrest, antitheft, anti-aging well lid, with the above-mentioned drawback of gram.
The technical solution of the utility model is:
A kind of erosion control is floating, fall arrest, antitheft, anti-aging well lid, and integral body is cylinder-like structure, and cylinder-like structure top is upper cover plate 6, and bottom is lower shrouding 8, and upper cover plate 6 is provided with pod apertures 1, and lower shrouding 8 is provided with lower pod apertures 5.
Also be provided with intermediate plate 7 between described upper cover plate 6 and lower shrouding 8, be divided into two-layer up and down by described cylinder-like structure inside.
Offer lightening hole 2 on described upper cylinder-like structure sidewall.Upper lightening hole 2 is communicated with the inner upper strata of cylinder-like structure.
Offer lower lightening hole 3 on described cylinder-like structure sidewall.Lower lightening hole 3 is communicated with the inner lower floor of cylinder-like structure.
Offer middle pod apertures 4 on described intermediate plate 7.
Described erosion control is floating, fall arrest, antitheft, anti-aging well lid are overall structure, and its material is resin glass fibre reinforced plastics.
The beneficial effects of the utility model are:
Erosion control of the present utility model is floating, fall arrest, the cleaning of antitheft, anti-aging well lid pipe well are simple especially, only needs to open well lid and just can carry out prune job
The utlity model has the floating function of erosion control: adopt the pod apertures structure, the impact force of the water in the minimizing pipe well to well lid,
The utlity model has anti-falling function: seldom, aging speed slows down the chance of irradiation, still has intermediate plate and lower shrouding to support, thereby reduces the possibility of falling.
The utlity model has the theft protection function: material adopts resin glass fibre reinforced plastics, belongs to not recyclable material, and waste and old shop is difficult for reclaiming.
The utlity model has the anti-aging function: adopt sandwich construction on structure, and centre is subject to sunlit chance seldom with bottom, thereby greatly slows down aging speed.
The accompanying drawing explanation
Fig. 1 is plan cross-section structural representation of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Fig. 3 is perspective view of the present utility model.
Fig. 4 is three-dimensional sectional structure schematic diagram of the present utility model.
In figure: 1 is that upper pod apertures, 2 is that upper lightening hole, 3 is that lower lightening hole, 4 is that middle pod apertures, 5 is that lower pod apertures, 6 is that upper cover plate, 7 is that intermediate plate, 8 is lower shrouding.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of erosion control is floating, fall arrest, antitheft, anti-aging well lid, and integral body is cylinder-like structure, and cylinder-like structure top is upper cover plate 6, and bottom is lower shrouding 8, and upper cover plate 6 is provided with pod apertures 1, and lower shrouding 8 is provided with lower pod apertures 5.
Also be provided with intermediate plate 7 between described upper cover plate 6 and lower shrouding 8, be divided into two-layer up and down by described cylinder-like structure inside.
Offer lightening hole 2 on described upper cylinder-like structure sidewall.Upper lightening hole 2 is communicated with the inner upper strata of cylinder-like structure.
Offer lower lightening hole 3 on described cylinder-like structure sidewall.Lower lightening hole 3 is communicated with the inner lower floor of cylinder-like structure.
Offer middle pod apertures 4 on described intermediate plate 7.
Described erosion control is floating, fall arrest, antitheft, anti-aging well lid are overall structure, and its material is resin glass fibre reinforced plastics.Adopt integrated poured method to be made.
The principle explanation of the new property of this practicality:
1) the floating function of erosion control realizes:
The well lid material adopts resin glass fibre reinforced plastics, and density is 2.4t/m
3, larger than the density of water.Adopt the pod apertures structure, reduce water in the pipe well impact force to well lid, enter the water of pressure bottom well lid that the water in well lid produces well lid the buoyancy of well lid is reached to relative equilibrium.
2) anti-falling function is realized:
Upper cover plate thickness is larger, guarantees in 20 years to have enough mechanical strengths, rigidity.The material adopted belongs to resin glass fibre reinforced plastics, and intensity is larger, and annual intensity descends 10%.Adopt multilayered structure, though the upper cover plate local ageing, and intermediate plate and lower shrouding are subject to sunlit chance seldom, aging speed slows down, and still has intermediate plate and lower shrouding to support, thereby reduces the possibility of falling.
3) the theft protection function realizes:
Material adopts resin glass fibre reinforced plastics, belongs to not recyclable material, and waste and old shop is difficult for reclaiming.
Manhole cover structure adopts loose structure, reduces the use function of well lid as his use.
4) anti-aging function realizes:
Material adopts resin glass fibre reinforced plastics, and serviceability temperature can reach 200 to 300 ℃, objectively slows down its aging speed.
Adopt sandwich construction on structure, and centre is subject to sunlit chance seldom with bottom, thereby greatly slows down aging speed.
Embodiment recited above is described preferred embodiment of the present utility model; not design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection all is documented in claims.
