Adjustable bracket is used in construction of back taper shell water tower

Technical Field

The utility model relates to a construction technical field specifically is an adjustable bracket is used in back taper shell water tower construction.

Background

In recent years, as the highway is continuously built and perfected in China, a service area water tower is arranged along the way of the newly built highway for storing water in the service area, and the water tower plays a role in adjusting and supplementing when the water supply amount is insufficient, and is an important component of living supporting facilities in the service area. Water towers are a relatively common and special building. The tower-shaped building is a high-rise tower-shaped building, a large water tank is arranged at the top end, and the higher the water storage tower in the tank is, the higher the water pressure is. The water tower is used to automatically deliver water to make tap water have a certain hydraulic lift. The water tank structure of the water tower is usually in the shape of an inverted conical shell, and the position with the largest diameter is 8 meters. The shell arm of the water tank is made of concrete with the thickness of 12 cm, and the height of the water tower building is 33.75 m.
