The Head of the Department of Building and Construction Technology Engineering (Mr. Dr. Riyad Abdel Abbas Ali) conducted a scientific workshop within the department entitled (Inspection Chamber) or what is called (Manhole or Applied). This workshop included the definition of the inspection chamber, its shapes, and the materials made of it. The summary of this workshop was as follows (the inspection room, which is the upper opening of the utility vault (or “concrete well”) buried underground, which is used as an access point for workers and/or inspection and maintenance equipment for utility networks buried underground (such as sewage networks and drains). Rainwater). These facilities are usually built at the intersections of pipes or channels of underground networks and at specific standard distances along the lines of those networks, in order to carry out sediment removal, connection and maintenance work for public facilities, and other services buried underground, including sewage, telephone and electricity. Rain and gas drains.
Usually, the “neck part” or “upper part of the structure” connected to these openings is made of brick, regular or reinforced concrete. In civil engineering works and applications, it is customary to call the well or concrete vault buried under the ground the name of the drain. The opening of the sink or drain is protected by a cover of the drain, which is a flat plug designed to prevent falling accidents. These plugs are usually made of metal, but It may be made of precast concrete, or blown plastic glass. The manhole (manhole) is usually equipped with a metal, polypropylene, or fiberglass staircase fixed to the inner side of the manhole wall to allow a smooth descent into the facility space.
The entry holes are usually circular in shape.
Condoms are generally created in urban areas, on streets and sometimes under sidewalks.
Matching places
Matches are created in specific places as needed, and match positions can be distinguished at
Changing the diameter of pipes used in the sewage network.
Changing the direction of pipes used in the sewage network.
Changing the inclination of pipes used in the sewage network.
Connection of drain lines to each other.
Change in the type of pipes used in the sewage network.
Matching forms
Compliance takes several forms in most cities in the world, including:
Square (1.2*1.2) meters.
Rectangle (0.8 * 1.2) meters.
Circular in shape with a diameter of 1 meter, 1.2 meters, or 1.5 meters.)
