Abstract
The utility model relates to a composite well cover, which is composed of a well cover 1 and a well seat 2. The utility model is characterized in that the well cover is composed of a steel ring 3, a metallic rib bar 4 fixed at the steel ring 3 and a non-metal material filling layer 5 filled in the steel ring 3; the well seat 2 is composed of steps 6, 7, a steel ring 9 of a rib sheet 8 and a non-metal material filling layer 10, wherein, the metallic rib bar 4 is enwrapped by the non-metallic material filling layer 5; the well cover 1 is hermetically matched with the step 6. The utility model has the advantages of light weight, high intensity, corrosion resistance, easy production and low cost. The material is easily obtained. The utility model fundamentally overcomes the problems of being easily crushed and being stolen.
Description
The utility model is relevant with the sewer well lid.
Existing sewer well lid is a casting iron well lid, the manufacturing cost height, and weight is big, is not easy to the breakdown maintenance.Well lid is frangible, and is easily stolen, often therefore causes casualties and property loss.
The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture, and long service life is convenient to install and maintenance combined manhole cover with low cost.
The utility model is made up of the well lid 1 and the well seat 2 that separate.Well lid 1 is fixed on the metal rib 4 on the steel ring 3 and is filled in the nonmetals packed layer 5 that contains rib 4 in the steel ring 3 and formed by steel ring 3.Well seat 2 is by being made up of with the nonmetals packed layer 10 that is filled in steel ring 9 steel ring 9 of step 6,7.Well lid 1 cooperates sealing with the step 7 of well seat 2.
Metal rib (4) on the steel ring 3 of the utility model well lid 1 can be formed plane grid by steel bar 11 and be welded on the steel ring 3, and other has arc-shaped steel bar 12 to be welded on the steel ring 3, and place, arc top is suspension ring 13, and suspension ring 13 expose packed layer 5.Packed layer 5 is made of glass fiber reinforced cement GRC material, and packed layer 10 is made of concrete.
The used metal material of the utility model is few, and is in light weight.Inserts can be glass fiber reinforced cement GRC material, and concrete, or other nonmetal reinforced composite are cheap, aboundresources, and corrosion-resistant, the life-span is long, and is with low cost.Because inserts embeds special steel ring, and the high strength rib is arranged, the intensity height is not broken, has solved the phenomenon of traditional product edge corner angle cracky.The utility model appearance standard, attractive in appearance, meet the standard of country fully about well lid, easy to manufacture, the fortune dress is convenient, and easy access has fundamentally solved the broken and stolen danger of well lid.Have good economic benefit and social benefit.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structure chart of steel ring 3 and rib 4.
Fig. 4 is the upward view of Fig. 1.
Following is embodiment of the present utility model:
The plane net trellis rib that welding is made of φ 4 screw-thread steels 11 in the steel ring 3.Other has 12 embowments of two φ, 12 screw-thread steels to become right-angled intersection to be welded on the steel ring 3, and the height of arc is less than or equal to the height of steel ring.Infall control sky is suspension ring 13.Glass fiber reinforced cement GRC material is filled in and constitutes composite material filling layer 5 in the steel ring 3.
Well seat steel ring 9 can be welded with muscle sheet 8 as shown in Figure 4.Concrete filling is in interior formation packed layer 10.Packed layer 10 also can be made of composite material.Steel ring 9 has step 6 and 7.The height of step 6 equates with well lid thickness.The internal diameter of step 6 is slightly larger than the diameter of well lid 1.
