Abstract
The utility model provides a pressure-resistant durable manhole cover which comprises a manhole cover body formed by casting concrete. The utility model is characterized in that a rigid framework composed of a circular disc, a cylinder at the middle part of the circular disc, and a connecting rod connecting the circular disc with the cylinder is arranged in the cover body, and fiber filaments are irregularly arranged in the concrete of the cover body. The pressure resistance, the tension resistance, the flexural strength, and the deformation resistance of the cover body are all greatly improved. Therefore, the utility model has the characteristics of long service life, convenient cover installation and disassembly, etc. Additionally, if the manhole cover is pushed out, the manhole cover has no recovery and reuse values. Therefore, the manhole cover is not profitable to lawbreakers, and a worry cover can be fundamentally into a reassurance cover.
Description
The utility model relates to the inspection shaft lid that a kind of sewer uses, especially a kind of resistance to compression durable basement well cover of stealing of preventing.
The inspection shaft lid that uses on road and the avenue at present mostly is steel-casting greatly, this gives some lawless person with opportunity, causing inspection shaft to cover the incident of this " black hole " eating the people happens occasionally, not only bring heavy economic losses to country, and bring harm to people's lives, for this reason, the somebody improves existing inspection shaft lid, as the inspection shaft lid made from discarded slag, and cylinder iron pours into a mould inspection shaft lid that forms or the like, the former is not withstand voltage, fragile, latter's easy fracture, poor toughness, can not fundamentally solve the resistance to compression of inspection shaft lid, durable problem, and have a lot of hidden danger.Therefore, be necessary existing inspection shaft lid is made improvement.
The purpose of this utility model is to overcome the deficiency of prior art, and the antitheft resistance to compression of a kind of energy, durable basement well cover are provided.
The utility model is realized by following technical proposal: it comprises by mixing the inspection shaft cap body that earth pours into, it is characterized in that being provided with in the lid rigid backbone that connecting rod constituted of living body and being connected them by the circle at disk and disk middle part, and in the mixed earth of lid the irregular fibre that is arranged with.Described cylindrical middle part is provided with through hole, makes it to constitute a hollow cylinder, is convenient to the dress lid and gets lid.Described disk links to each other with the cylinder top and bottom respectively with at least three braces by at least two waling stripes, thereby constitutes comparatively stable steel work reinforcing rib, to strengthen the non-deformability of lid.All be arranged with fibre in the mixed earth in the longitudinal section of described lid and cross section brokenly,, improve lid intensity to increase the toughness of lid.
The utility model compared with prior art has following advantage and effect: collapse skeleton owing to be provided with rigidity in lid, and mix the fibre that is provided with irregular alignment in the earth at lid, therefore, no matter be resistance to compression, tension, the flexural strength of lid, still the non-deformability of lid all is greatly improved, therefore, can improve the application life of this product.In addition dress lid, to get lid all comparatively convenient, the more important thing is because this inspection shaft lid in case release, does not just have the value of recycling, therefore, or else can allow those lawless persons lucrative, can fundamentally become " worrying lid " and be " relieved lid ".
Fig. 1 is the longitudinal plane structure figure of the utility model;
Fig. 2 is the cross-sectional configuration figure of the utility model.
Below in conjunction with accompanying drawing the utility model is described further, is not limited to this but hold within the utility model.
Among the figure, 1 for mixing earth inspection shaft cap body, 2 for constituting the mixed earth of lid, 3 for being located at the fibre that mixes the irregular alignment in the earth 2,4 is the steel structure framework cylinder, its upper end links to each other with disk 6 by four horizontal brace rods 5, and the lower end links to each other with disk 6 by six roots of sensation brace 7, and the middle part is provided with through hole 8.
Claims (4)
1, a kind of resistance to compression durable basement well cover, comprise by mixing the inspection shaft cap body that earth pours into, it is characterized in that being provided with the rigid backbone that connecting rod constituted of living body and being connected them in the lid by the circle at disk and disk middle part, and in the mixed earth of lid the irregular fibre that is arranged with.
2, inspection shaft lid according to claim 1 is characterized in that described cylindrical middle part is provided with the through hole that can make it to constitute hollow cylinder.
3, inspection shaft lid according to claim 1 is characterized in that described disk links to each other with the cylinder top and bottom respectively with at least three braces by at least two waling stripes.
4, inspection shaft according to claim 1 lid is characterized in that being arranged with fibre brokenly in the mixed earth in the longitudinal section of described lid and cross section.
