Also comprise rubber washer, described rubber washer is between well lid pedestal and outer well lid.

The sewer well of prior art is topmost is circular sewer, a small amount of is rectangle or square sewer, when sewer is rectangle or when square, the well lid pedestal is that strip is symmetrically distributed in lower well inwall, well lid is the shape consistent with the sewer shape, be slightly less than sewer, be embedded into by castellated snap close in the conduit of castellated draw-in groove, connect and fix.

When selecting the shape of normally used circular sewer, in outer well lid, well lid be circle, and the well lid pedestal is annular.

Described well lid pedestal also comprises folding section, the well lid pedestal can be amounted to and is put into sewer when the sewer of transformation prior art like this, and bad entering while avoiding entering sewer mouth because of the well lid pedestal is installed after launching.

Described card arm is loop configuration, is positioned at well lid pedestal lower outside, is embedded in the borehole wall.The utility model beneficial effect is:

1. the utility model adopts the structure of inside and outside two-layer well lid, interior well lid adopts the grid type design, in use, run into and need a large amount of drainage situations, only outer well lid need be removed, can reach draining purpose smoothly, the interior well lid of grid type also baffle is lived the solid flowed into water, has effectively prevented the obstruction of sewer.Even if outer manhole cover damage or stolen has occurred, or need a large amount of drainings to take the phenomenon of outer well lid away, because the existence of interior well lid is arranged, also can effectively protect passing people, make it to escape injury.

2. between outer well lid dividing plate and outer well lid, rubber washer is set, decrease the noise that occurs while being connected with metal of original metal.

3. outer well lid of the present utility model and interior well lid are all to be fixed on the well lid pedestal by castellated snap close and castellated draw-in groove embedded, very difficult coming off and stolen phenomenon, and.

4. a preferred version of the present utility model adopts the well lid pedestal of similar F shape, and the well lid pedestal is nested in borehole wall top, and when having external force to be pressed on outer well lid, the well lid pedestal helps dispersive pressure, makes outer well lid not yielding impaired.The outer well lid of prior art often adopts an end to be bolted on the borehole wall, outer well lid can rotate by bolt, facilitate folding, but well cover for sewer often well lid is exposed to the weather and is drenched with rain, easily corrosion, and this kind of structure easily is out of shape and burst apart in the situation that well lid is subject to External Force Acting, cause the damage of well lid.The utility model adopts nested clamping, and it is convenient to install and open, and stressedly evenly is not easy compressive deformation and damages, and because of its double-decker, use safer reliable, suitable applying.
