The specific embodiment

The utility model will be further described below in conjunction with Figure of description and embodiment:

As Figure 1-3, a kind of high-strength steel fibre inspection shaft lid, become the ground supporting use in the end of inspection shaft lid, it comprises integrated inspection shaft lid body 1, the bottom of inspection shaft lid body 1 is equipped with the steelframe member 2 of booster action, build layer of concrete 3 on the steelframe member 2, be equipped with one deck on the concreting layer 3 and prevent the wire gauze 4 of concrete block leakage current, build one deck and the equal layer of concrete 5 in inspection shaft lid body 1 top on the wire gauze 4, described inspection shaft lid body 1 top iron block bends inwards, form decorative cover 6, described decorative cover 6 forms the plane with layer of concrete 5.

In order to increase the intensity of whole inspection shaft lid, described steelframe member 2 is welded by angle bar or screw-thread steel intersection, be arranged on inspection shaft lid body 1 bottom, described steelframe member 2 is welded by angle bar or screw-thread steel intersection, this steelframe member 2 through inspection shaft cover, between lower floor's lid, steelframe member 2 is designing requirements of having satisfied intensity of load, makes that inspection shaft lid supporting capacity is strong, resistance to compression, tension, bending resistance, excellent in cushion effect promptly have robust characteristics.Also be filled with concrete between the space of steel member skeleton.

Described inspection shaft lid body 1 is one-body molded by iron block or other materials similar, because the inspection shaft lid often is on street or the track, constantly bear to not timing pedestrian or vehicle trample or spreading, be easy to generate phenomenons such as fracture or fragmentation, inspection shaft lid body 1 top iron block of the present utility model is arranged to bend inwards, form decorative cover 6, the size of bending is generally the 2-15 millimeter, promptly the width of the decorative cover that forms 6 is the 2-15 millimeter, preferred bending is of a size of the 2-5 millimeter, and promptly the width of the decorative cover that forms 6 is the 2-5 millimeter, can increase the lifting surface area of whole inspection shaft cap surface like this, reduce local bearing capacity, thereby avoid or reduce the generation of fracture or broken phenomenon.And add one deck wire gauze 4 between described layer of concrete 3 and the layer of concrete 3, in case the layer of concrete 5 on upper strata is when having breakage, concrete block directly drops, and causes the injustice on road surface, influences attractive in appearance.

Described layer of concrete 5 upper surfaces are set as anti-skidding, wear-resisting Argyle, in case rainy day is too sliding, old man and child walk upward dangerous, and layer of concrete 5 upper surfaces also are equipped with 2-4 aperture, take out the inspection shaft lid when being convenient to keep in repair in roadbed.

According to actual needs, described inspection shaft lid body 1 can be set to circular configuration, square structure or other structures.

Inspection shaft lid of the present utility model, during use, on the way spread earlier the manhole cover base 9 that is equipped with protective screening 8, again inspection shaft is covered as for manhole cover base 9, the upper surface of whole inspection shaft lid is equal with ground, because inspection shaft covers the flanging of bending and has formed decorative cover 6, decorative cover 6, layer of concrete 5 are equal at face with the road, increase lifting surface area, can reduce vehicle like this and open out-of-date pressure to layer of concrete 5, increase the service life, be after preventing that the inspection shaft lid is stolen and be equipped with the inspection shaft net on the base, child falls into sewer because of carelessness, causes the accident.
