Composite foundation of large-diameter high-temperature fused salt storage tank and using method thereof
The invention provides a composite foundation of a large-diameter high-temperature fused salt storage tank and a using method thereof. The composite foundation comprises a variable rigidity top plate,a rigid base plate and an outer ring wall, wherein the variable rigidity top plate is connected with the outer ring wall, the rigid base plate is integrally poured with the outer ring wall, the variable rigidity top plate is tightly attached to the bottom of the storage tank, an outer thermal insulation layer is arranged between the variable rigidity top plate and the outer ring wall, an intermediate thermal insulation filling layer is arranged between the variable rigidity top plate and the rigid base plate, and warehouse separating steel beams are arranged in a vertical direction of the intermediate thermal insulation filling layer at equal intervals. According to the invention, load of a tank top, a tank wall and a tank body insulation layer and vertical pressure of fused salt in the storage tank are directly borne through the variable rigidity tapered top plate and a special-shaped ring beam, and all vertical loads and foundation reaction forces are borne through the rigid base plate; and the outer ring wall bears the lateral pressure of the upper fused salt and a thermal insulation material, the intermediate thermal insulation filling layer realizes thermal insulation and heat preservation, all parts are clear in division of labor and cooperatively work, and the composite foundation is new composite foundation capable of integrating bearing and insulating of the large-diameter high-temperature fused salt storage tank.
本发明提供了一种大直径高温熔盐储罐复合式基础及其使用方法，包括变刚度顶板、刚性底板和外环墙，变刚度顶板与外环墙部相接，刚性底板与外环墙一体浇筑，变刚度顶板紧贴储罐底部，变刚度顶板与外环墙之间设有外保温层，变刚度顶板和刚性底板之间设有中间隔热填充层，中间隔热填充层沿竖直方向等间距设有分仓钢梁。本发明通过变刚度锥形顶板和异形环梁直接承担罐顶、罐壁及罐体保温层的荷载以及储罐内熔盐的竖向压力，通过刚性底板承担所有竖向荷载及地基反力，通过外环墙承担上部熔盐及隔热材料的侧向压力，中间隔热填充层实现隔热保温，各部分分工明确，协同工作，是一种能够满足对大直径高温熔盐储罐的承载、保温于一体的新型复合式基础。
