Abstract

The invention discloses an easy-to-replace LNG (liquefied natural gas) storage tank shock isolation cushion and a replacement method thereof. The shock isolation cushion comprises a shock isolation cushion body, a shock isolation cushion upper padding plate and a shock isolation cushion lower padding plate; the shock isolation cushion upper padding plate is arranged on the upper portion of the shock isolation cushion body, and the shock isolation cushion lower padding plate is arranged on the lower portion of the shock isolation cushion body; the shock isolation cushion upper padding plate is connected with an upper flange through upper fastening bolts, and the shock isolation cushion lower padding plate is connected with a lower flange through lower fastening bolts; the upper fastening bolts or the lower fastening bolts are bolts capable of being unscrewed; upper flange bolts are arranged on the upper plate and used for being connected with an LNG storage tank bearing platform; lower flange bolts are arranged on the lower flange and used for being connected with an LNG storage tank pile foundation. When the LNG storage tank shock isolation cushion is replaced, the padding plates need not to be jacked by a jack, cracks are avoided, and disturbance of the structure is guaranteed to the utmost degree.

Description

technical field [0001] The invention relates to an easily replaceable LNG storage tank vibration isolation pad and a replacement method thereof, belonging to the technical field of liquefied natural gas (LNG) transmission and distribution. Background technique [0002] The main component of liquefied natural gas (LNG) is methane, which is obtained by cooling natural gas to -162°C under normal pressure. The density of liquefied natural gas is about 450kg / m 3 , the volume is about 1 / 600 of the gaseous state. LNG storage tanks are the main equipment for storing LNG, which can be divided into single-capacity tanks, double-capacity tanks, full-capacity tanks and membrane tanks. At present, the most widely used is the full-containment tank. The full-containment tank generally consists of the following parts: foundation, cap, outer tank wall, tank roof, inner tank, and cold insulation materials. The overall load of the storage tank is relatively large, and the foundation general...
