Method for rectifying deviation of large storage tank by jack-up

Abstract

The invention relates to a method for rectifying the deviation of a large storage tank by jack-up. The method specifically comprises the following steps that firstly, a deformation monitoring system is established, wherein the deformation monitoring system is used for monitoring degree of storage tank sedimentation, monitoring storage tank displacement and monitoring deep soil deformation; secondly, a storage tank foundation is reinforced; thirdly, the storage tank is filled with water and pre-pressed; and fourthly, the deviation of the storage tank is rectified by jack-up. The method is suitable for most of building structure forms and various foundation soil, and the operation space is small; in the method, due to the fact that grouting pipe trepanning and grouting are conducted from the periphery of a building structure, the building structure is not damaged; through monitoring synchronous with construction, the precision of rectifying deviation by jack-up can be effectively controlled; and after foundation reinforcing and deviation rectifying, all loads are applied to meet the using requirement, and the treatment effect is very visual.

Description

technical field [0001] The invention relates to a method for correcting a large storage tank by jacking up and belongs to the technical fields of chemical engineering, petroleum and construction foundation deviation correction. Background technique [0002] Due to problems such as improper selection of the foundation and uneven distribution of soft soil, after the completion of the construction of the main body of the storage tank structure or during the long-term operation, the foundation of the storage tank will undergo settlement and uneven settlement, causing the tank body to tilt, and sometimes cracks may occur. Severe cases can lead to structural damage and even overall instability, bringing great safety hazards to production and operation. If the tank is dismantled and rebuilt, the construction cost will be higher and the construction period will be longer, and the whole line will be shut down for a long time due to the reconstruction of a single building structure, r...

AI Technical Summary

Problems solved by technology

[0004] In view of the frequent occurrence of settlement and uneven settlement of storage tanks at present, in order to ensure stable operation in the later stage and meet the requirements of not affecting production, in order to solve the above problems, the present invention provides a method for post-reinforcement of storage tank foundation and jacking correction The method, because of its universal applicability and non-destructiveness to the storage tank itself and surrounding structures, has great advantages in engineering
