Ultra-large silo prestress tension process method
The invention discloses an ultra-large silo prestress tension process method. The method comprises the following steps that a hole channel is formed in a buttress column of a silo; jack oil pressure gauge readings corresponding to the tension anchor control force, and the extension amount of each jack piston are solved; penetrating of a steel strand is carried out; a first buttress column 1, a third buttress column 3 and a fifth buttress column are subjected to graded tension through two jacks from top to bottom, and a second buttress column 2, a fourth buttress column 4 and a sixth buttress column 6 are subjected to graded tension through two jacks from bottom to top; hole channel grouting is carried out; pilasters are subjected to anchor sealing; and concrete is cured and end forms are removed.
本发明公开了一种超大型筒仓预应力张拉工艺方法包括以下步骤：在筒仓一扶壁柱设置孔道，求出张拉锚控制力所对应的千斤顶油压表读数，千斤顶活塞的伸长量，穿设钢绞线，自上而下用两个千斤顶分级张拉第一扶壁柱1、第三扶壁柱3和第五扶壁柱，自下而上两个千斤顶分级张拉第二扶壁柱2、第四扶壁柱4和第六扶壁柱6，孔道灌浆，附壁柱封锚，混凝土养护、端模拆除。
