“…Riser pipe mounted on oil drilling rigs in the Arctic Ocean is a typical example of its application. The pipe-in-pipe, here introduced, is filled with granular material such as sand instead of ceramic (Kanie et al, 2015). The purpose of the core material is not to increase the flexural rigidity but to transmit stress between double pipes within the section and to prevent local buckling known as Brazier effect as shown in Figure 12.…”

Ground freezing has been broadly applied to construction and maintenance works of infrastructures because of its environmental friendliness. Since freezing technology represented by ground freezing can improve the strength of soil as well as its water-tightness, it becomes an essential technology for construction and maintenance of urban infrastructures where the use of space in underground has already been highly integrated. In this paper, overview of the freezing technology is introduced with some important characteristics of freezing soil for practical application. In addition, freezing technology is used for interesting works which could not be completed without freezing, and the state of the arts in freezing technology is presented. A pipe-in-pipe, now the authors are developing, is an example to utilize the potential of frozen sand, and the effect of freezing is explained with experimental results.
