A boss-shaped manhole cover is made of grid-shaped cast iron reinforcing ribs, an annular cast iron jacket which is connected with the reinforcing ribs and is provided with a step-shaped cross section, and concrete. The manhole base is composed of the grid-shaped cast iron reinforcing ribs and an annular inner jacket whose cross section is in an L shape and the concrete. The utility model has the advantages that the well cover and the base are provided with higher compression resistance and folding strength, the periphery is not easy to damage, the service life is long, and the appearance is beautiful. Because the embezzlement value is low, the purpose of antitheft can be obtained.
Description
The utility model relates to a kind of well head overburden.
At present, the stolen phenomenon of casting iron well lid that is used to cover well head is very general, and this has not only destroyed urban facilities, and and easily damages accident.In order to solve the stolen problem of casting iron well lid, the well lid that adopts steel concrete to make is also arranged, this well lid to steal value not high, can reach antitheft purpose, but there is the edges of the periphery cracky in it, not only sturdy and durable inadequately but also inaesthetic shortcoming.
It is a kind of sturdy and durable that the purpose of this utility model is to provide, cast iron concrete manhole cover that bearing capacity is strong and well seat.
The purpose of this utility model is achieved in that the cast iron concrete manhole cover is to make boss shape by latticed reinforcing rib and concrete, it is step-like ring jacket that its edge is provided with section, it can avoid the well lid edge breakage like this with the concrete hoop in cover, make it sturdy and durable.Latticed reinforcing rib in this sheath and the concrete is connected as a single entity, and strengthens supporting capacity, and can prevent that sheath is stolen.Cast iron concrete well seat inner edge promptly is provided with the L-shaped ring-type inner sheath of section with the well lid contact position, reinforcing rib in it and the well seat concrete is connected as a single entity, to increase the impact resistance at well seat mouth place, can not cause the breakage of well seat, and can prevent that sheath is stolen because of well lid weight is heavier.
Characteristics of the present utility model are: well lid, well seat have higher compression and cut folding intensity, and its periphery is cracky not, long service life, and good looking appearance, value is lower owing to stealing, and therefore can reach antitheft purpose, guarantees the complete of urban facilities, is beneficial to public safety.
Fig. 1 is a structural representation of the present utility model.
Be described in further detail below in conjunction with accompanying drawing;
As shown in Figure 1, boss shape well lid (1) is step-like annular cast iron sheath (3) and concrete (4) by latticed cast iron reinforcing rib (2) or reinforcing bar and coupled section and makes, reinforcing rib can be established one deck or upper and lower two layers, and well lid is provided with the pore of being convenient to open.Reinforcing rib, pore and sheath adopt high-quality grey iron cast solid, the concrete that stirs is injected in the sheath, by the machinery shake smash, steam curing makes the higher well lid of fineness.During use well lid is buckled on the well seat.Well seat (5) is to be made by latticed cast iron reinforcing rib (6) or reinforcing bar and coupled L-shaped ring-type cast iron inner sheath (7) and the concrete (8) of section.Its material therefor, production technology are all identical with well lid.
