By adopting above-mentioned technical proposal, rationally using existing structure, using the upper surface of manhole shaft shoulder body as sub- lid Position is placed, sealing ring is set up, further increases the sealing property in manhole shaft shoulder body.

This utility model is further arranged to：Described sub- cover rim is circumferentially provided with positioning bending, the positioning bending with it is close Seal inner peripheral surface shape is adapted.

By adopting above-mentioned technical proposal, sealing ring inner circumferential, fitted seal circle inner circumferential is rationally utilized to realize that son is covered and placing While accurate contraposition.

This utility model is further arranged to：Manhole shaft neck ring, described people are provided with above described manhole shaft shoulder body The upper surface of hole well shoulder body is provided with the locating slot for placing sealing ring, and described sealing ring is arranged towards manhole shaft neck ring inner peripheral surface There is the sealing block that section is serrated.

By adopting above-mentioned technical proposal, mounting groove increases the mounting stability of sealing ring, and that section is serrated is close Envelope block then greatly enhances sealing property.

This utility model is further arranged to：The described son side of covering is provided with the hook for lifting sub- lid.

By adopting above-mentioned technical proposal, hook is set up, son lid can be opened by hook shape component, and without the need for manually being removed with handss Fortune, simplifies opening ways.

This utility model is further arranged to：Described hook includes the first parallel hook and the second hook, described The first hook and the second hook bill in the opposite direction, described first hook and the second hook are relatively set with phase The suspension cavities of UNICOM.

By adopting above-mentioned technical proposal, adopt head for T-shaped auxiliary member, the first hook of first insertion and second hook Between, T-shaped transverse ends are rotated to the suspension cavities of different hooks, you can antithetical phrase lid carries out stable lifting, are difficult to break off relations, further fast Son lid is taken out and opened to speed.

This utility model is further arranged to：Described hook is fixedly installed on hook installing plate, and described son is covered and set It is equipped with and the mounting groove that plate shape is adapted is installed with hook, is provided between described hook installing plate and son lid dismountable solid Determine part.

Its position is locked by adopting above-mentioned technical proposal, positioning of the mounting groove as hook installing plate, fixture It is fixed, hook installing plate fast assembling-disassembling is realized, the coupler body of multi-form is conveniently replaceable, or more renew after long-time use, Fixture is conventional components, can fix for bolt.

With reference to the accompanying drawings and detailed description this utility model is further described.
