Newly built inserting rod for brick chimney: 8 steel pipes of φ 73 and φ 60 are selected, and the length is slightly smaller than the inner diameter of the cylinder body. The small steel pipe is sheathed in the large steel pipe to form four groups of expandable inserting rods. The inserting rods must have positioning screws that can limit the expansion. In this way, it can save a lot of scaffold erection and removal works and heavy derrick lifting equipment installation and installation. The following focuses on the simple and reliable construction method and several key problems to be controlled. After each step of bricklaying is completed (generally controlled at the bricklaying height of about 1.2m), the other two groups of inserting rods are installed, the hanging ladder is hung, the scaffold board below is moved up, and then the lower inserting rod is removed, and the plug hole is blocked. In this way, each time the bricklaying of a step is completed, the inserting rod is reversed upward once, and the holding platform is moved up by one step.
