Covering apparatus for opening of underground pipeline or box

Abstract

There is disclosed a covering apparatus for a personnel opening of a sewer, a tap water pipeline, or an underground pipeline or box for telecommunication or electric power devices. More particularly, the covering apparatus includes an adjustable height corresponding to the rising of paving. The covering apparatus includes seat assembly and a cover installed on the seat assembly. The seat assembly includes a primary seat and at least one secondary seat. The primary seat defines a cavity for receiving the cover or, if necessary, a lip of the secondary seat. The secondary seat defines a cavity for receiving the cover. Thus, the height of the covering apparatus can be increased. Level difference between new paving and the cover can be eliminated, and the safety of pedestrians, riders and drivers using the new paved road is improved. Moreover, the covering apparatus can be assembled effectively regarding time and labor.

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.

[0010] Another objective of the covering apparatus according to the present invention is to provide a covering apparatus with a height adjustable easily and effectively regarding labor and time.

[0011] According to the present invention, a covering apparatus includes a seat assembly and a cover for closing the seat assembly. The cover includes a lip on the bottom. The seat assembly includes a primary seat and at least one secondary seat. The primary seat is hollow and includes a first cavity in the top for receiving the lip of the cover and a second cavity therein. The secondary seat is hollow and includes a first cavity in the top for receiving the lip of the cover, a second cavity therein and a lip on the bottom for insertion in the second cavity of the primary seat or another secondary seat. Thus, the secondary seat can be provided between the cover and the primary seat in order to easily adjust the height of the covering apparatus if necessary.

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.
