Abstract
The development of H-jointed steel pipe sheet piles and H-H joints commenced in 2000 as one of the steel pipe sheet pile (SPSP) technologies. H-jointed SPSPs are a building material in which two steel pipes and an H-steel are integrated by welding them beforehand in a factory, and H-H joints are a joint section in which two H-steels with different sizes are combined together. In this research, we conducted field installation and permeability tests for H-jointed SPSPs with H-H joints as their first application in the field; this was conducted in December 2006. In a series of field installation and permeability tests, we verified the factors considered in the construction field when using SPSP methods. In this paper, the field installation and water interception performance of H-jointed SPSPs with H-H joints are reported based on the results obtained from the field installation and permeability tests. In the field installation of H-jointed SPSPs with H-H joints, we observed that rotating breaks did not occur. Therefore, a highly accurate installation was possible for H-jointed SPSPs with H-H joints in the field.
