Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 to 4, the steel fiber nodular cast iron manhole cover in this embodiment includes a manhole cover and a manhole base, the manhole base is annular, the manhole cover is located in the manhole base, the manhole base is installed at a wellhead of a road surface, an upper end surface of the manhole base is flush with the road surface, and asphalt or concrete is used for fixing the periphery of the manhole base. The well lid comprises an annular body 11, a framework 13 and reinforcing ribs 12, wherein the framework 13 is connected with the annular body 11, the framework 13 and the annular body 11 are also connected through the plurality of reinforcing ribs 12, and 6 reinforcing ribs 12 are uniformly connected to form double supporting loads with the framework 13; the framework 13 is made of nodular cast iron, and the annular body 11 and the reinforcing ribs 12 are made of steel fibers and are formed with the framework 13 in a composite mode to manufacture the well cover. 4 fixing lugs 14 are uniformly arranged on the annular body 11 in the radial direction; the well seat comprises a horizontal ring 21 and a vertical ring 22, and the vertical ring 22 is provided with a groove 23 matched with the accommodating fixing lug 14. During the installation, well seat bearing surface is equipped with the flexible cushion of shock attenuation, and the fixed ear 14 of well lid aligns with recess 23 and covers tightly, can the noise reduction. The inspection well cover of the embodiment is economical and practical, large in bearing load and long in service life.

On the basis, as shown in fig. 2 and 3, the framework 13 is designed to be hollow; the surface of the framework 13 is a spherical surface; the fixing lug 14 is provided with a connecting hole. The hollow design can facilitate observation in the well, the well cover does not need to be opened, and the use is convenient; the bearing capacity that the sphere design made the well lid is strong, in order to fix well lid and well seat, well lid and well seat are equipped with the fixed orifices, make the difficult stolen or aversion of well lid.
