Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of prestressing systems for liquefied natural gas storage tanks, and in particular relates to an oblique prestressing system for liquefied natural gas storage tanks. Background technique [0002] Liquefied natural gas (LNG) is natural gas that changes from a gaseous state to a liquid state when it is cooled to -162°C under normal pressure. The volume is about 1 / 600 of the volume of the same amount of natural gas, and the density is about 480kg / m3. Liquefied natural gas is colorless, odorless, non-toxic and non-corrosive, and can evaporate directly after leakage. The prestressed system of the concrete exterior wall of the storage tank is an important part of the storage tank construction, and its design optimization is the focus and difficulty of the storage tank construction work. [0003] The transportation and storage of liquefied natural gas mainly adopts liquefied natural gas storage tanks. Due to the i...
