Super-large thermal insulation storage tank with double-curved double-layer cable as tank roof and its construction method

Abstract

The present invention relates to a super-large thermal insulation storage tank using hyperboloid double-layer cables as tank roof and a construction method thereof, wherein the super-large thermal insulation storage tank using hyperboloid double-layer cable as tank roof includes tank top, tank wall and tank bottom , the tank roof adopts a hyperboloid double-layer cable structure, and the inner ring beam is closed with a reticulated shell structure, and the roof panel is laid on the hyperboloid double-layer cable structure and reticulated shell structure. The ring beam, the outer ring beam and the high-strength spring steel pipe are composed, and the tank wall is composed of the inner plate, the outer plate, the sandwich insulation board, and ordinary concrete. The sandwich insulation board is set between the inner plate and the outer plate, and the three are connected by anchor bolts. The parts are fixed, and ordinary concrete is layered between the inner plate, outer plate and interlayer insulation board. Two annular I-shaped steel beams are arranged on the top of the tank wall, and the two annular I-shaped steel beams are connected as a whole by transverse stiffeners. Form a ring steel truss. The invention solves the problems of small volume and poor thermal insulation effect of conventional steel storage tanks.

Description

technical field [0001] The invention relates to a storage tank in the field of civil engineering, in particular to a super-large thermal insulation storage tank with a hyperboloid double-layer cable as a tank roof and a construction method thereof. Background technique [0002] With the rapid development of my country's economy, high-strength materials and advanced technical equipment are constantly improving. At the same time, China's demand for oil and storage capacity are also increasing, which drives the construction and rapid development of super large storage tank design. With the increase of oil storage and processing volume, the volume requirements for temporary storage equipment are also increasing. Conventional storage tanks can no longer meet the development needs well, and the research on ultra-large storage tanks has attracted more and more attention. . Vertical storage tanks are used in major oil fields and enterprises because of their simple construction, lar...
