Embodiment 1

[0024] The invention provides a steel storage tank prefabricated concrete conical segmented ring wall foundation, such as Figure 1 to Figure 5 As shown (taking the section number 12 and the cross-section rectangle of the surrounding wall as an example), it includes the following technical conditions:

[0025] (1) The foundation of the ring wall is a segmented prefabricated concrete member; the number of segments (that is, the arc segment) is determined according to the diameter of the foundation (generally the same as the diameter of the storage tank); the length of the segment (that is, the arc length) is determined according to the diameter of the foundation, However, 1.0 to 2.0 times the height of the ring wall is the best; the cross section of the ring wall is rectangular or truncated, and its height and width are determined according to the storage and transportation process and geological conditions;

[0026] (2) The number of segments is even and equal along the circum...

Abstract

The invention relates to a steel storage tank precast concrete conical sectional type ring wall foundation mainly solving the problems that in the prior art, standard part prefabrication production cannot be conducted easily and ring wall stress is not reasonable. The steel storage tank precast concrete conical sectional type ring wall foundation is adopted, a continuous ring wall foundation is formed by connecting and combining a series of upright conical components and reverse conical components with one another in a self-embedded manner, vertical force is converted into axial pre-press force in the ring wall components through the effect of a vertical load on the upper portion, the axial tension generated by the inner side of a ring wall to active soil pressure is reduced, the balance of the axial force in the ring wall foundation is achieved by arranging additional hoop bodies on the outer side surfaces of the ring wall upright conical components in a matched manner, and therefore the technical scheme, with the optimal price-performance ratio, of the ring wall foundation design is achieved, the problem is well solved, and the steel storage tank precast concrete conical sectional type ring wall foundation can be used in steel storage tank precast concrete conical sectional type ring walls.

Description

technical field [0001] The invention relates to a prefabricated concrete conical segmented ring wall foundation for a steel storage tank. Background technique [0002] Steel storage tank foundations generally have slope protection type and ring wall (beam) type. The ring wall type foundation is widely used because it can adjust the uneven settlement of the tank foundation and occupies less land. It is suitable for all kinds of soft soil foundations. The ring wall foundation can be divided into cast-in-place and prefabricated, but the utilization rate of the prefabricated formwork is low, especially when the prefabricated parts are connected by post-casting belt (concealed column form) connection method, additional formwork and reinforcement are required , The construction is troublesome and the maintenance period is long, so the current project basically adopts the cast-in-place ring wall foundation. [0003] CN201210273498.X discloses a ring wall foundation, which is compo...
