Oblique prestressing system of liquefied natural gas storage tank
The invention belongs to the technical field of liquefied natural gas storage tank prestressing systems, and discloses an oblique prestressing system of a liquefied natural gas storage tank. The oblique prestressing system comprises a wall, wherein a bearing platform formed by concrete pouring is arranged at the bottom of the wall, a ring beam is arranged on the periphery of the top of the wall, two rows of wall prestressing anchor bearings are installed on the periphery of the top of the wall in parallel, a first threading pipe is connected between one row of wall prestressing anchor bearings and the bearing platform, a second threading pipe is connected between the other row of wall prestressing anchor bearings and the bearing platform, the first threading pipe and the bearing platform are vertically installed, and the second threading pipe and the bearing platform are installed in an inclined mode. According to the oblique prestressing system, a triangle is formed by the first threading pipe, the second threading pipe and the ring beam, and a triangle is formed by the second threading pipe, the bearing platform and the first threading pipe, so that the stability of the prestressing system can be guaranteed only by using a small number of steel strands and threading pipes, and the investment of money and time is greatly reduced.
本发明属于液化天然气储罐预应力系统技术领域，公开了一种液化天然气储罐的斜向预应力系统，包括墙体，墙体底部为混凝土浇筑成型的承台，所述墙体的顶部一周设置有环梁，所述墙体的顶部一圈平行安装有两排墙体预应力锚座，其中一排墙体预应力锚座与承台之间连接有第一穿线管，另一排墙体预应力锚座与承台之间连接有第二穿线管，所述第一穿线管与所述承台垂直安装，所述第二穿线管与承台倾斜安装；本发明第一穿线管、第二穿线管和环梁之间构成三角形，第二穿线管、承台和第一穿线管之间构成三角形，因而只需使用少量的钢绞线及穿线管，即可保证预应力系统的稳定性，大大减少了资金和时间的投入。
