[0002] Civil engineering air ducts are channels for air circulation built with materials such as concrete and bricks. Such air ducts are usually used in the ventilation systems inside buildings, and are typically used to connect indoor air conditioning systems and the outdoor environment to ensure air circulation and distribution.
[0003] In order to improve ventilation efficiency and reduce fire risks, sometimes it is necessary to renovate civil engineering air ducts. For example, as shown in Figure 1 , the left roof beam 1, the middle roof beam 2, and the right roof beam 3 are all vertically arranged and all arranged in the front-back direction and spaced apart from each other left and right. The left floor slab 4 is horizontally arranged and located between the left roof beam 1 and the middle roof beam 2 and is respectively connected to the left roof beam 1 and the middle roof beam 2. The right floor slab 5 is located on the right side of the right roof beam 3 and is connected to the right roof beam 3.

On the right side, it ventilates from above the right floor slab 5 and through the right air shaft shear wall 7. It is necessary to make a side opening in the right air shaft shear wall 7 (make a side opening at the position 9 of the right opening to be made) and it is necessary to build the right shaft roof 15 (see Figure 2 ), the front retaining wall of the right shaft, the rear retaining wall of the right shaft, and the right side retaining wall of the right shaft.
