Description

Double-layer double-protection inspection manhole cover

technical field

The utility model relates to a supporting facility technology in road construction, in particular to a well cover and a well seat on a channel and a site inspection well, specifically a double-layer double-protection inspection well cover.

Background technique

The traditional inspection manhole cover is a single-layer design, and the manhole cover and well seat are all cast iron manhole covers and well seats. The main problems of this kind of manhole cover and well seat are: 1 serious theft; 2 high cost; 3 not tight sealing, There is often rainwater and dust intrusion, which cannot meet the needs of power, telecommunications, water supply, heating and other departments. 4 High energy consumption and heavy pollution.

Utility model content

The technical problem to be solved by the utility model is: the cast iron manhole cover is seriously stolen, the cost is high, and rainwater, dust, etc. are easy to intrude. It provides a double-layer double-shield with reasonable structure, low cost, good sealing effect, and not easy to damage. Check manhole covers.

The technical scheme that the utility model solves the above problems is:

A double-layer double-protection inspection well cover, including a well cover, an inner cover, and a well base. An inner cover is also provided under the well cover, and prefabricated steel plates are provided on the sides of the well cover; the inner and outer sides of the well base are respectively There is a prefabricated steel plate flush with the well cover; the inner wall of the well cover is provided with a well-shaped reinforcing rib.

The utility model has reasonable structure and low cost, which not only solves the problem of serious theft of inspection well covers and well seats, but also prevents the problems of rainwater and dust intrusion.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

A double-layer double-protection inspection well cover, including a well cover, an inner cover, and a well seat, and a layer of inner cover 2 is arranged under the well cover 1, and a prefabricated steel plate 4 is provided on the side of the well cover 1. Prefabricated steel plates 5 and 6 flush with the well cover 1 are installed on the inner and outer sides of the well seat 3 respectively, and the inner wall of the well cover 1 is provided with a well-shaped reinforcing rib 7 .

The well cover 1 and the well seat 3 are formed by casting straight steel fiber reinforced skeleton and sandstone concrete. The inner cover 2 adopts a butterfly-shaped engineering plastic cover.

During normal use, the inner wall of the well base 3 is provided with two pole bosses 9, 10, the inner cover 2 is seated on the lowermost boss 10 of the well base 3 first, and then the well cover 1 is seated on the boss 9 on the top of the well base 3 superior. When needing to be opened, after opening the well cover 1 from the crowbar hole 8 on the well cover 1, the inner cover 2 is gently picked up.

Claims (3)
