[0002] In underground building construction, due to the complexity and diversity of the pipeline system, it is often necessary to connect pipes of different diameters. Variable diameter pipe joints can perfectly solve this problem. They can connect pipe sections of different diameters in sequence to ensure the integrity and smoothness of the pipeline system. Variable diameter pipe joints mainly include two types: circle-to-circle (changing the diameter of the circle) and circle-to-square (converting circular pipes to square pipes).

[0003] In the prior art, variable diameter pipe joints are mainly installed and fixed by using the steel reinforcement framework or formwork support frame in the concrete shear wall during pre-burying in underground building construction. However, such installation structures have the following disadvantages: (1) During formwork reinforcement, the installed variable diameter pipe joints are easily disturbed, changing the installation position and causing deviation in the position of the two ports after concrete pouring is completed; (2) The variable diameter pipe joints have a large self-weight, and the steel reinforcement framework or formwork support frame cannot bear the gravity load of the pipe joints. Forced fixation not only causes quality hazards but also causes significant safety hazards.
