Covering apparatus for opening of underground pipeline or box

Abstract

A covering apparatus includes a seat assembly and a cover. The seat assembly includes at least a seat with a plurality of flights on an internal side. Each of the flights includes a plurality of steps. The cover includes, on a lower side along an edge, a plurality of flights corresponding to the flights of the seat. Each of the flights of the cover includes a plurality of steps corresponding to the steps of each of the flights of the seat. Various combinations of the steps of each of the flights of the cover can be positioned on related combinations of the steps of each of the flights of the seat so that the cover can be positioned on various levels on the seat.

Description

BACKGROUND OF INVENTION [0001] 1. Field of Invention [0002] The present invention relates to an opening of an underground pipeline or box and, more particularly, to a covering apparatus for such an opening. The covering apparatus includes an adjustable height based on paving. Moreover, the covering apparatus can be assembled effectively regarding time and labor. [0003] 2. Related Prior Art [0004] A covering apparatus is used for an opening of a sewer, a tap water pipeline, or an underground pipeline or box for devices for fire fighting, telecommunication or electric power in order to control the access thereto of personnel and equipment. A typical covering apparatus includes a hollow seat, annular or rectangular, and a cover installed on the hollow seat. In use, the covering apparatus is secured to the top of the sewer, pipeline or box. The cover must be flush with paving in order to keep the paving smooth. [0005] When the covering apparatus is installed initially, the cover can be ...

AI Technical Summary

Benefits of technology

[0009] An objective of the covering apparatus according to the present invention is to increase the safety of pedestrians, riders and drivers by providing a covering apparatus with a height adjustable based on paving.

Problems solved by technology

However, because there is no design for adjusting the height of the covering apparatus, if the paving is renewed, or the sewer, pipeline or box is remade, a level difference will occur between the cover and the paving.

This is particularly so in the country where the paving is often renewed by providing a 10-cm layer of asphalt while the height of the covering apparatus cannot be adjusted.

Yet, the pit still exists and causes pedestrians, riders and drivers to bump over it, and sometimes causes traffic accidents.

The pedestrians, riders and drivers are endangered.

This however demands a lot of time and labor.

Furthermore, the road must be closed and the traffic is jammed.

However, as the hollow seat is not broken, such replacement causes unnecessary waste and increases the cost of public works.

Such a finding process demands a lot of labor and time.

This means a high cost of maintenance or repair.

This could mean loss of property or life in an emergency.

The conventional covering apparatus fails to provide proper solutions to the problems such as the un-adjustable height, the demand for time and labor.

The traffic safety is affected, and the cost is increased.
