Abstract
The utility model belongs to urban construction facilities and particularly relates to an arched manhole cover. A cambered plate with a cambered surface facing upwards is fixedly mounted on the inner side of the bottom end of a barrel, the cambered plate is gradually thickened from the edge to the center, the arch rise dimension of the chambered plate and the diameter dimension of the barrel are in a proportion of 1:2-3, concrete is fixedly arranged at a position, above the cambered plate, in the barrel, and a strip-shaped through hole is vertically concentrically formed in the center of the concrete and the cambered plate. The arched manhole cover is high in compressive strength, less in potential safety hazards, low in manufacturing cost, good in burglary prevention performance and long in service life.
Description
Technical field
The utility model belongs to urban construction facility, relates generally to various facility well lids in urban operating mechanism.
Background technology
At present, the casting iron well lid that the well lid using on the well head of the various channels such as the upper and lower water lines of urban construction facility, transmission of electricity, air pipe, lightguide cable link is still manufactured taking single cast iron materials is as main, and all rounded tabulars of casting iron well lid; For improving compressive strength, on the flat casting iron well lid of circle lower surface, reinforcing rib is set.But, in actual use, due to the defect in structure design, often there is casting iron well lid and rolled by loaded vehicle the phenomenon of damage, cause potential safety hazard; In addition, this structure manhole cover anti-theft poor performance, Loss Rate is high.
Summary of the invention
The purpose of this utility model is exactly the problem existing for above-mentioned prior art, and design provides a kind of Arched well cover of new construction, reaches that compressive strength is high, sturdy and durable, the object of good anti-theft effect.
Basic Design of the present utility model is, on inside portion, cylindrical shell bottom, is fixedly mounted with cambered plate, described cambered plate arch upward cambered surface upward, and the gauge of described cambered plate strengthens gradually from the Chu Xiang centre, edge of cambered plate; The diameter dimension Φ ratio of the sagitta size H of described cambered plate and cylindrical shell is 1: 2～3; In inner barrel, be positioned at cambered plate above position be fixedly mounted with concrete; Strip through-hole is set with one heart along the vertical direction on the centre of described concrete and cambered plate, so far forms Arched well cover.
The utility model is according to mechanics principle, employing arch upward cambered plate that cambered surface configures upward and cylindrical shell, concrete combined structure, not only increased substantially the compressive strength of well lid, long service life, has eliminated potential safety hazard, and reduce well lid manufacturing cost, meanwhile, owing to having increased the overall weight of Arched well cover and the thickness of Arched well cover, make standing to coordinating the degree of depth to strengthen of Arched well cover and well lid base, the theftproof performance that has improved well lid, has reduced Loss Rate.
Brief description of the drawings
Fig. 1 is Arched well cover general structure schematic diagram.
Piece number explanation in figure:
1, cambered plate, 2, cylindrical shell, 3, concrete, 4, strip through-hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model optimum implementation is described in detail.A kind of Arched well cover is fixedly mounted with cambered plate 1 on cylindrical shell 2 inside portions, bottom, described cambered plate 1 arch upward cambered surface upward, and the gauge of described cambered plate 1 strengthens gradually from the Chu Xiang centre, edge of cambered plate 1; The diameter dimension Φ ratio of the sagitta size H of described cambered plate 1 and cylindrical shell 2 is 1: 2～3; In cylindrical shell 2 inside, be positioned at cambered plate 1 above position be fixedly mounted with concrete 3; Strip through-hole 4 is set with one heart along the vertical direction on the centre of described concrete 3 and cambered plate 1.The cross section external shape of described cylindrical shell 2 rounded or oval or square or rectangle or polygon.Described cylindrical shell 2 and cambered plate 1 can be made by cast iron, resin, carbon element, polypropylene or other materials.
When installation, utilize lifting device to coordinate with the insertion of strip through-hole 4, Arched well cover entirety is sling, and be placed on well lid base, and ensure that plane and ground are in the same plane on Arched well cover.
