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 cons

Embodiment

[0048] Embodiment: A kind of storage tank outrigger construction technology, comprises the following steps:

[0049] A. Production process of storage tank outriggers: the production of storage tank outriggers includes the following steps:

[0050] a. Basic acceptance: basic acceptance shall be carried out in accordance with the relevant provisions of the "Code for Construction and Acceptance of Vertical Cylindrical Welded Steel Storage Tanks GB50128-2005", and detailed basic acceptance records shall be made. Subsequent operations can only be carried out after passing the test;

[0051] b. Line setting: Determine the midline point of the installation position of each leg according to the construction drawing, measure and determine the elevation of the bottom plane of the cup mouth, and combine the section size of the steel section to determine the dimension line of the outer edge of the bottom of the leg, and set out the line on the bottom plane of the corresponding cup mout...

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...
