Liquid sloshing preventing method of concrete rectangular liquid storage structure

Abstract

A liquid sloshing preventing method of a concrete rectangular liquid storage structure comprises a first step of determining and carrying out foundation treatment according to a geotechnical engineering investigation report of a site; a second step of laying a plain concrete cushion (1) and erecting templates, setting reinforcing steel bars and arranging embedded parts on the plain concrete cushion (1); a third step of pouring a bottom plate (2) and wall plates (3) of the rectangular liquid storage structure, and arranging grooves (5) with the same thickness as a vertical partition plate (4) at an inner side of the wall plates (3); a fourth step of according to chemical properties of a liquid inside the structure, selecting and making a material into the vertical partition plate (4), and reserving holes (6) in the vertical partition plate (4); a fifth step of determining the thickness h of the vertical partition plate (4) according to the described formula; and a sixth step of installing the vertical partition plate (4) into the grooves (5).

Description

technical field [0001] The invention relates to a liquid storage structure, in particular to a concrete rectangular liquid storage structure in which vertical partitions with holes can prevent liquid from sloshing. Background technique [0002] At present, the concrete rectangular liquid storage structure is widely used in various fields of national lifeline projects. It is related to the lifeline of the national economy, such as large water storage tanks for urban water supply and drainage and large liquid storage devices for petrochemical enterprises. In areas with high seismic fortification intensity, when such structures encounter strong earthquakes during normal use, there will be the following problems: [0003] 1. If the liquid level in the rectangular liquid storage structure fluctuates greatly, the seismic force of the structure will increase, and the cross section and steel bars of the structure will increase. Insufficient design considerations will directly lead ...

AI Technical Summary

Problems solved by technology

[0003] 1. If the liquid level fluctuations in the rectangular liquid storage structure are large, the seismic force of the structure will increase, and the cross section and steel bars of the structure will increase.

If the design is not considered enough, it will directly lead to cracking or damage of the liquid storage structure, which will seriously affect people's production and life, and cause great economic losses to the country and the people.

[0004] 2. If the liquid level in the rectangular liquid storage structure fluctuates greatly, causing the stored liquid to overflow or even splash, it will have a certain impact on the surrounding environment, and in severe cases, it will cause secondary disasters such as fire, explosion, and environmental pollution.

[0005] 3. If the liquid in the rectangular liquid storage structure sloshes under the earthquake, it will affect the stability of the system
