Storage tank supporting leg construction process

Abstract

The invention discloses a storage tank supporting leg construction process, and relates to the technical field of storage tank construction. The problem that existing storage tank supporting leg construction is poor in quality is solved. According to the technical scheme, the construction process comprises the following steps of A, the storage tank supporting leg manufacturing procedure; and B, the storage tank supporting leg lifting procedure including the substeps of checking before steel part mounting, b, part mark marking, c, cable wind rope and anchor arranging, d, scaffold preparing, e,cup bottom adjusting, f, steel column mounting, g, steel column correcting including 1, column foundation elevation, 2, alignment of longitudinal and transverse cross lines, and 3, column body perpendicularity correction, h, cross beam mounting, and i, cross beam correcting including 1, elevation adjusting and cross beam perpendicularity correcting. Through actual elevation measuring, longitudinaland transverse cross line alignment, level gage operation and the manner of plumb hanging by a crane, the mounting precision of steel columns and cross beams can be improved, and the storage tank supporting leg construction quality is improved.

Description

technical field [0001] The invention relates to the technical field of storage tank construction, more specifically, it relates to a construction technique for storage tank outriggers. Background technique [0002] The storage tank is a large storage device for liquefied gas. With the continuous development of the current society, the demand for energy is increasing, so the demand for storage tanks is also gradually increasing, and the requirements for storage tank volume are also gradually increasing. big. [0003] When carrying out storage tank construction, it is first necessary to build the outriggers of the storage tank. The outriggers of the storage tank are the structures that support the entire storage tank. With the increasing requirements for the volume of the storage tank, the weight of the storage tank itself and The increase in the weight of liquefied gas that can be stored in the storage tank has higher and higher requirements for the construction quality of t...

Problems solved by technology

[0003] When carrying out storage tank construction, it is first necessary to build the outriggers of the storage tank. The outriggers of the storage tank are the structures that support the entire storage tank. With the increasing requirements for the volume of the storage tank, the weight of the storage tank itself and The increase in the weight of liquefied gas that can be stored in the storage tank has higher and higher requirements for the construction quality of the storage tank outriggers, which means that the error requirements in the construction process of the storage tank outriggers are becoming more and more strict. In the construction of some storage tank outriggers, most of them rely on experience to control the construction quality. The quality of storage tank outriggers completed by different construction personnel is quite different. The storage tank outriggers constructed by many construction personnel cannot meet the needs of large-volume storage tanks. There is an urgent need for a construction method that can improve the construction quality of storage tank outriggers
