Description

Technical Field

[0001] The utility model relates to the technical field of spliced ​​open pipe corridors, in particular to a spliced ​​open pipe corridor with a manhole cover. Background Art

[0002] A pipe gallery is a corridor for pipelines. In chemical and related factories, many pipelines are concentrated together and arranged along the outside of the equipment or factory buildings. They are usually in the air and supported by brackets to form a corridor-like appearance. A few pipe galleries are also located underground. It is the main place for the concentrated laying of pipelines of large-scale equipment. It is composed of columns, beams and trusses of steel or reinforced concrete structures. It can be divided into single-layer or multi-layer, passable or non-passable, etc.

[0003] Pipe corridors usually require maintenance personnel to enter regularly to clean and maintain or observe the internal conditions, which requires some manhole covers to be reserved on the pipe corridor for easy entry or opening for observation. However, in the existing manhole cover design, the internal pedals are mostly installed by welding, which is prone to corrosion and fall off after long-term use, posing many safety hazards during use. Therefore, a spliced ​​open pipe corridor with manhole covers is proposed to solve the above problems. Utility Model Content
