Shaft structure for improving section utilization and design method of shaft structure

The invention discloses a shaft structure for improving section utilization and a design method of the shaft structure. A shaft section comprises a rectangular section in the middle and semicircular sections on two sides of the rectangular section. The diameter edges of the semicircular sections are as long as the length of the two side edges of the rectangle, the diameter edges of the semicircular sections coincide with the two side edges of the rectangle, the inner wall of the shaft section is parallel to the diameter edges of the semicircular sections, at least two groups of main buntons are arranged, and a lifting shaft guide for lifting a container is arranged between the main buntons. The shaft structure further takes advantage of the high utilization rate of the rectangular shaft section of the shaft and good force on the circular section of the shaft. Under the same section area, the size of the spaces such as ladder compartments can be increased, the shaft structure is more conducive to escape, and t
