(Summary description)Anchor devices are evenly arranged around the lower part of the main container and the secondary container, the main container has 72 pieces, and the secondary container has 104 pieces, and they are reliably connected with the foundation embedded anchoring device, so that the main container and the secondary container are fastened to the base platform of the storage tank. Above, to prevent the equipment from tilting and lifting under the action of working load and external force (such as wind load, seismic load, etc.).

Anchor devices are evenly arranged around the lower part of the main container and the secondary container, the main container has 72 pieces, and the secondary container has 104 pieces, and they are reliably connected with the foundation embedded anchoring device, so that the main container and the secondary container are fastened to the base platform of the storage tank. Above, to prevent the equipment from tilting and lifting under the action of working load and external force (such as wind load, seismic load, etc.).
When the anchoring device of the main vessel passes through the thermal angle protective bottom plate, a flat sleeve + sealing plate combination structure is adopted to minimize the stress transferred to the thermal angle protective layer bottom plate through the anchoring device.
A, bottom insulation layer. The ZES-8O0 foam glass brick is laid between the bottom plate of the main container and the bottom plate of the secondary container as the bottom insulation layer and bears the weight of the main container and the medium, and the pearl sand reinforced concrete ring beam is used in the pressure-bearing annular area directly under the main container wall (The steel bar is required to be stainless steel) to distribute the load, and the lower part of the concrete ring beam uses ZES-1200 high-density foam glass bricks. The insulation layer at the bottom of the storage tank is as follows from top to bottom: the main container bottom plate (edge plate + medium plate)-C45 concrete leveling layer-pearl sand concrete ring beam, ZES-SO0 foam glass brick (same layer)-C45 concrete leveling layer- Thermal corner protective layer bottom plate-C45 concrete leveling layer-ZES1200 foam glass brick, ZES-8O0 foam glass brick (same layer)-C45 concrete leveling layer-secondary container bottom plate.
B, thermal corner protection insulation layer. The 150mm ring-shaped space between the wall panel of the secondary container cylinder and the thermal corner protection cylinder is built with ZES8O0 foam glass bricks as cold insulation materials and supports to isolate the cold transfer occurring in the direction of the sidewall of the storage tank. Low temperature glue is applied between the foam glass brick layer and the layer of the thermal corner protection thermal insulation layer as a bonding agent, and the upper sealing ring plate of the thermal corner protective thermal insulation layer is filled with glass fiber wool with a thickness of 50mm after compression.
Insulating layer in the direction of the side wall of the main container cylinder. The outer wall of the main container is provided with a complete circle of combined flexible elastic layer (from the inside to the outside: cotton cloth, elastic cotton, cotton cloth, and glass cloth), which is used to buffer the side pressure of pearl sand, and the annular space between the main container and the secondary container is densely filled. The pearlescent sand is used to isolate the transfer of cold energy in the direction of the side wall of the main container.
Lay 10 layers of glass fiber wool on the suspended ceiling. The thickness of the single layer of glass fiber cotton shall not be less than 100mm. The total thickness after laying is within the range of 800mm-1000mm to keep the top of the main container with good thermal insulation performance.
