Composite shock insulation and energy consumption foundation device for large vertical oil storage tank

Abstract

The invention discloses a composite shock insulation and energy consumption foundation device of a large vertical oil storage tank. A concrete lower ring beam is arranged on the ground; a sand cushion layer is arranged at the bottom of the concrete lower ring beam; lower rolling ring beam groove bodies are evenly formed in the top of the concrete lower ring beam; a concrete upper ring beam is correspondingly arranged at the top of the concrete lower ring beam; the lower portion of the concrete upper ring beam is provided with upper rolling ring beam groove bodies; steel balls are arranged between the lower rolling ring beam groove bodies and the upper rolling ring beam groove bodies; and the concrete lower ring beam and the concrete upper ring beam are correspondingly arranged. The stability of the device can be improved, the shock absorption and energy dissipation capacity of the device is improved, and the manufacturing cost of the shock isolation device is reduced; the structure is simple, material taking is convenient, installation and construction are easy, and manufacturing cost is low; and the device is high in vertical pressure bearing capacity and good in shock isolation effect, has an instant reset function, can achieve the purpose of supporting an upper structure, can also achieve the purpose of isolating earthquake from being input to the upper structure, and reduces damage of destructive earthquakes to the large-scale vertical storage tank.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a composite shock-isolation foundation device for petroleum storage tanks. Background technique [0002] Vertical storage tanks are extremely important industrial equipment in the petrochemical industry. With the upgrading of my country's energy reserve plan, the structural forms of storage tanks are developing in the direction of large-scale, floating, and thin-walled. Ensuring the safety of important facilities and equipment in the petrochemical industry, especially the storage tank structure during normal production or sudden disasters (such as earthquake disasters) is the prerequisite for the continuous, stable and safe development of the petrochemical industry and its storage and transportation system. The storage tank structure is the most widely used storage equipment in the field of petrochemical industry, and it is also one of the structures that threaten the most s...

AI Technical Summary

Problems solved by technology

In actual engineering, the foundation structure of vertical storage tanks mostly adopts the ring wall foundation, which is difficult to meet the applicability, poor stability, and poor shock isolation effect
