The water inlet tower body is often designed with multiple layers of connecting beams to enhance the overall stability of the water inlet tower. The construction of the longitudinal and transverse connecting beams in the water inlet tower body is often done by manually using steel pipes, steel sections, square timber, wooden formwork, etc. to set up scaffolding as a cast-in-place connecting beam operation platform in the air. Scaffolding supports are erected on the top surface of the connecting beams. The top surface of each layer of connecting beams is relatively narrow. Workers need to erect and dismantle the scaffolding in a limited space, and the safety risk of working at height is high. The upper cast-in-place connecting beam supports are generally erected on the lower connecting beams, and the top width of the connecting beams is limited.
