The pouring method of the welding electric gourd increase is to make the top circle wall board and vault first after the layout of the storage tank is laid, and then use the electric gourd on the inside of the storage tank on the side column. Skills, improve the wall board, set up other circles of the lower parts of the bottom welding ring in turn, and finally complete the group pair of welding of the bottom wall board and the bottom plate welding welding. After the foundation of the re -inspection tank is correct, the group welding plate, temporary support, and the welding ring wall board and the second circle of wall boards are laid in order. After the installation of the wall of the first and 2nd circles, the facilities such as the improvement of the border columns, electric gourds, swelling circle workers, central masts, balanced steel wire ropes and electrical lighting are lifted to the can. Install the vault and its accessories, and install the gap at the vault of the border column. After the arch was installed, the swelling circle workers are installed at the lower edge of the 1st wall board to support the round and improvement of the tank; then the border columns, central masts, electric gourds and balanced steel wire ropes are installed, and Hang up the inverted chain of the electric gourd on the hook of the swelling circle workmanship, and then pre -tighten the improvement mechanism. The installation of the inverted system is completed, and after the inspection is correct, the tank is improved. After the promotion is in place, there are two wall boards, and two living mouths are evenly arranged on the tank wall round. The unnecessary part of the group is tightened. In the third circle of the wall, the welding of the wall plate was completed, and after the inspection was correct, the tank was improved. Since then, the cycle is recovered, until the lap of the wall plate is set up at the last lap of the bottom. After the lap of the wall plate is completed, the tank body is slightly improved, the temporary support on the bottom plate is removed, and then the improvement mechanism is reduced. The tank is on the bottom plate. Slim. Since the temporary support of the storage tank is to be removed in the end, the maximum weight G of the increase is the weight of the total storage tank bottom plate of the total storage tank, and the weight of the bottom plate accounted for a small proportion of the total weight of the tank. The institutional force analysis is calculated by the total weight of the tank, which is equivalent to amplifying the coefficient of the Loading School check -in safety.
