Abstract

The utility model belongs to a maintenance device for pipelines, which particularly relates to a manhole cover and a manhole ring used on pipeline maintenance equipment for ingress and egress. The manhole cover on the manhole ring is round in shape. A stilb hole and an exhaust hole are arranged on a sector-shaped strip. The back side of the manhole cover is provided with #-shaped reinforcing ribs on which rope-shaped bodies are embedded, and a laminar metal net is clamped in the manhole cover body. Convex reinforcing ribs are arranged on the side wall of a manhole seat which is provided with fixed manhole seat pin holes. The manhole cover is installed on the manhole ring into integration. The utility model replaces cast iron manhole covers and is suitable for pipeline opening devices of service installations of water feeding and exhaust, coal gas, heat supply, communication, electric force, etc.

Description

Manhole cover and well ring

The utility model metal conduit service equipment, particularly a kind of well lid and walling crib of passing in and out on the pipe-line maintenance equipment of being used for.

At present, on the pipeline of communal facilities, for set well lid and the walling crib of maintenance, repair, adopt cast iron casting usually, but often go out the active phenomenon because of society and problem of management.And the well lid that anti-thefting facility is housed and the walling crib that adopt in recent years, well lid and walling crib are connected as a single entity needs to use special tool to open, and increases cost of manufacture, makes troubles to use.The well lid that also has glass-reinforced plastic material to make because of material and structure problem, distortion and damage occur in addition, increases unsafe factor to piping facility.

The purpose of this utility model is to overcome above technical deficiency, and provide a kind of simple in structure, a kind of new pattern manhole cover and walling crib easy to use.

Task of the present utility model is, well lid on walling crib is circular, the centre is circular, be followed successively by endless belt, fan belt strip, the endless belt is formed, and has location lifting hole and steam vent on fan-shaped strap, is " well " shape reinforcing rib at the back of well lid, be embedded with restiform bodies at reinforcing rib, in the well lid body, accompany the laminated metal net.Walling crib is made up of raised platform around a well, manhole cover base, well seat, is provided with the reinforcing rib of projection on the sidewall of well seat, gains in strength, and the well seat has fixedly well seat pin hole, and walling crib is installed on the raised platform around a well, and well lid is installed on the walling crib and becomes one.

The utility model is a major ingredient with the waste or used plastics, and is aided with reinforcing materials such as flyash, adhesive, and intensity surpasses casting iron well lid and walling crib, and acid and alkali-resistance, but load-bearing 50t bogie roll flawless, does not have and damages.

Specifically describe with by way of example below in conjunction with accompanying drawing.
