Adjustment method of the bracket device in the hydrostatic test of the spherical tank in service

Abstract

The invention discloses a bracket device for a hydrostatic test of an in-service spherical tank and a regulating method. An iron plate of the bracket device is laid below the spherical tank; a plurality of jacks are uniformly distributed on the iron plate at intervals; a plurality of uprights are respectively arranged at the top ends of piston rods of the plurality of jacks; a plurality of rubber cushion blocks are arranged at the tops of the plurality of uprights; a plurality of tie beams and diagonal ties are connected with the plurality of uprights and a flange plate. According to the regulating method, the jacks are adopted to jack up the uprights to enable the rubber cushion blocks to be in contact with the tank wall; in the water injection process of the spherical tank, foundations are required to be uniformly settled; when the spherical tank is respectively under different water injection conditions, a water level is adopted to record settlement data of the foundations of a plurality of spherical tank support pillars; when nonuniform settlement occurs to a certain spherical tank support pillar, the supporting forces of the adjacent uprights for the spherical tank are immediately regulated by the jacks until the settlement data of the certain spherical tank support pillar reaches a normal value. The bracket device takes an auxiliary supporting effect on the spherical tank. The method ensures that the bracket device implements effective supporting on the spherical tank so as to ensure that the hydrostatic test of the spherical tank is successfully carried out.

Description

technical field [0001] The invention relates to an adjustment method of a bracket device in a hydrostatic test of an in-service spherical tank. Background technique [0002] Spherical tank is a large-capacity steel container equipment, which is mainly used to store liquid or gaseous materials, such as liquefied petroleum gas, liquefied natural gas, liquid oxygen, liquid ammonia, liquid nitrogen, etc. The general spherical tank is set on the ground foundation through several support columns; compared with the general cylindrical container, under the same diameter and pressure, the shell wall thickness of the spherical tank is only half of the cylindrical container, the amount of steel is saved, and it occupies an area Small, simple basic engineering. However, the manufacturing, welding and assembling requirements of spherical tanks are strict, the inspection workload is heavy, and the manufacturing cost is relatively high. [0003] Spherical tanks shall be regularly inspect...

Problems solved by technology

When the spherical tank is subjected to the hydrostatic test according to the conventional method, the corresponding water should be injected according to the volume of the spherical tank first. At this time, the supporting column of the spherical tank bears the weight of the water and the self-weight of the spherical tank, which is about several thousand tons of load, so the original spherical tank supports The column will not be able to bear all the load, and the uneven settlement of the foundation will cause the support column of the spherical tank to tilt seriously, causing the weld between the spherical wall and the support column to tear, causing the spherical tank to overturn, and the consequences are disastrous
