Background technology
The maintenance overhaul mouth of present buried piping lane all must arrange well lid, but be through daily permanent practicality, and metal well lid place has outside corrosion phenomena, usually can be stolen, causes the appearance major accident of pedestrian and vehicle.Therefore nonmetal manhole cover arises at the historic moment; but intensity is a problem being not easy to overcome always; the position ground that ground is connected with well lid usually there will be and subsides; well lid is caused more easily to damage; finally cause the well lid life-span shorter; especially the service ports nonmetal manhole cover of super large is just difficult to overcome load-bearing problem, and still weight and volume is just too heavy to thicken well lid rear load-bearing Resolving probiems, and construction is just more difficult.
Large maintenance well needs access device, if with dome, diameter can be excessive, and improper difficulty of construction is large and cost is high.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of practicality, ultra-large type manhole reliable, reasonable in design maintenance well well lid.
The utility model adopts following technical scheme: a kind of ultra-large type manhole maintenance well well lid, comprises the framework that is arranged on maintenance pit periphery and covers the cover plate that framework flushes with ground; Described framework comprises backing ring, the enclosure be arranged on backing ring, be arranged on the supporting plate bottom backing ring, the top board being arranged on enclosure top and the frame reinforcing bar cage be embedded in framework, described supporting plate is fixedly connected with frame reinforcing bar cage with top board, and described backing ring extends to form holder shoulder to framework center; Described cover plate comprises the outer eaves board being positioned at cover plate surrounding and the loaded plate be connected with outer eaves board one, described outer eaves board matches with holder shoulder, described outer eaves board alien invasion is provided with backplate, be provided with bottom described loaded plate and strengthen holder, be equipped with lid reinforcing bar cage in described cover plate, described lid reinforcing bar cage is fixedly connected with backplate; Be equipped with reinforcing rib sheet in described cover plate, described reinforcing rib sheet is extended to by outer eaves board strengthens holder; Described cover plate is one-body molded, and described supporting plate, top board and backplate are steel plate strip, and described framework is rectangle, and described cover plate is the rectangular slab matched with framework.
Furtherly, described cover plate end face is provided with antiskid groove, and multiple described antiskid groove is evenly distributed on cover plate end face.
Furtherly, described frame reinforcing bar cage and lid reinforcing bar cage are all three-dimensional cages of multilayer.
Furtherly, fill concrete or engineering plastics in described framework and cover plate.
The beneficial effects of the utility model: the well lid of rectangle can adapt to the profile of equipment, effectively utilize limited space, reduce construction cost, in the bottom of framework, the plainly-packed steel plate strip in bottom, colliding with of carrying can be avoided, avoid the surrounding ground tire that subsides to cause damage to framework, cover plate arranges the physical damage that backplate prevents when carrying maintenance, increases application life; Being embedded in reinforcing bar cage in framework and cover plate can stiffener intensity, supporting plate, top board and backplate and reinforcing bar cage are fixed and can be avoided coming off, connect tightr, the further increase life-span, reinforcement holder bottom cover plate increases heavy burden further, gravity is passed to backing ring by outer eaves board by cover plate, and reinforcing rib sheet can be strengthened outer eaves board further and strengthen the connection of holder, increases the load of cover plate.
Cover plate end face arranges antiskid groove, increases frictional force; The every root arrangement of reinforcement of three-dimensional cage of multilayer is interconnected, and increases the load of cover plate and framework further; The theme of cover plate and cover plate can concrete, also can be the corrosion resistance that engineering plastics increase well lid.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-3 and specific embodiment, utility model is described in further detail:
As shown in Figure 1, 2, a kind of ultra-large type manhole maintenance well well lid, comprises the framework 1 that is arranged on maintenance pit periphery and covers the cover plate 2 that framework 1 flushes with ground; Described framework 1 comprises backing ring 11, the enclosure 12 be arranged on backing ring 11, be arranged on the supporting plate 13 bottom backing ring 11, the top board 14 being arranged on enclosure 12 top and the frame reinforcing bar cage 15 be embedded in framework 1, described supporting plate 13 is fixedly connected with frame reinforcing bar cage 15 with top board 14, and described backing ring 11 extends to form holder shoulder 16 to framework 1 center; As shown in Figure 2,3, described cover plate 2 comprises the outer eaves board 21 being positioned at cover plate 2 surrounding and the loaded plate 22 be connected with outer eaves board 21 one, described outer eaves board 21 matches with holder shoulder 16, described outer eaves board 21 alien invasion is provided with backplate 23, be provided with bottom described loaded plate 22 and strengthen holder 24, be equipped with lid reinforcing bar cage 25 in described cover plate 2, described lid reinforcing bar cage 25 is fixedly connected with backplate 23; Be equipped with reinforcing rib sheet 26 in described cover plate 2, described reinforcing rib sheet 26 is extended to by outer eaves board 21 strengthens holder 24; Described cover plate 2 is one-body molded, and described supporting plate 13, top board 14 and backplate 23 are steel plate strip, and framework 1 is rectangle, and described cover plate 2 is the rectangular slabs matched with framework 1.
The well lid of rectangle can adapt to the profile of equipment, effectively utilize limited space, reduce construction cost, in the bottom of framework, the plainly-packed steel plate strip in bottom, colliding with of carrying can be avoided, avoid the surrounding ground tire that subsides to cause damage to framework, cover plate arranges the physical damage that backplate prevents when carrying maintenance, increases application life; Being embedded in reinforcing bar cage in framework and cover plate can stiffener intensity, supporting plate, top board and backplate and reinforcing bar cage are fixed and can be avoided coming off, connect tightr, the further increase life-span, reinforcement holder bottom cover plate increases heavy burden further, gravity is passed to backing ring by outer eaves board by cover plate, and reinforcing rib sheet can be strengthened outer eaves board further and strengthen the connection of holder, increases the load of cover plate.
