The water tank of invert tapered shell used to be prefabricated and lifted,which lead to increase water leakage and long construction period.In order to improve the inadequate,it will be necessary to research a kind of construction technology with short construction period and high quality.This paper discusses some construction schemes for the water tank of invert tapered shell,determining the total construction scheme is cast-in-situ concrete by the shelf bracket of the steel combine full-ball supporting frame,checking and calculating the bearing capacity of the construction scheme in two cases,describing the site arrangement of bracket,support system,concrete casting and the control measures of security risks.Applying the shelf bracket of the steel combine full-ball supporting frame to construct the water tank of invert tapered shell,which reaches the goal with short construction period and high quality,which can be referred for similar engineering.
