Testing the superblock deck by dynamic loads

Abstract

Tyumen oil and gas industry province is being developed with the use of complete block construction. Especially increases the importance of building large blocks with installed equipment and superblocks on a floating mobile base. Styrofoam concrete is used to insulate the superblock deck. According to the developed methods, the adhesion strength of Styrofoam concrete to the superblock deck was tested and its characteristics for vibration resistance after the test were studied. The thermal characteristics of Styrofoam concrete used for superblock deck insulation are established, taking into account the vibration effects during transportation and operation. For testing, the deck fragment was installed in a climate chamber, and heat flow and temperature sensors were fixed to the surface of the fragment. As a result, it was found that dynamic loads reduce the resistance to heat transfer by 8-12 % due to the opening of cracks and the appearance of convective heat exchange. It is shown that the actual thermal resistance of the superblock deck with a thickness of 0.25 m and after exposure to dynamic loads remains at a sufficiently high level.
