作为一种新型建筑钢材,钢板桩具有许多独特的优点:一是防水性能好、强度高、使用寿命长,其使用寿命可达50年;二是能够重复利用,节约成本;三是效果显著,特别是在塌方、流沙、防洪等项目中的应用,效果极佳;四是施工简单,施工速度快。钢板...作为一种新型建筑钢材,钢板桩具有许多独特的优点:一是防水性能好、强度高、使用寿命长,其使用寿命可达50年;二是能够重复利用,节约成本;三是效果显著,特别是在塌方、流沙、防洪等项目中的应用,效果极佳;四是施工简单,施工速度快。钢板桩的种类主要有 U 型、Z 型、AS 型等几大类,而每一种类又有各自不同的规格,比如 U 型钢板桩根据宽度有400、500、600mm 等不同规格。在国外钢板桩广泛的应用于基础防渗、围堰、码头、堤岸防护等等,据资料显示。展开更多
H-H joint of ＂H-jointed SPSP with H-H joint＂, which is made up of interlocking two H-steel sections of different sizes, is the one of SPSP＇s joint to improve the hydraulic conductivity. ＂H-H jointed SPSP with H-H ...H-H joint of ＂H-jointed SPSP with H-H joint＂, which is made up of interlocking two H-steel sections of different sizes, is the one of SPSP＇s joint to improve the hydraulic conductivity. ＂H-H jointed SPSP with H-H joint＂ is expected to be applied to a vertical cutoff wall in coastal landfill sites. In H-jointed SPSP with H-H joint, the H-joint is completely imperviousness. H-H joint, however, is pervious at interlocked state because a gap of 8 to 11 mm is left between the interlocking flanges, therefore, a water interception treatment must be conducted to seal the gap. The water shielding treatment of H-H joint is executed by coating the gaps with a water-swelling sheet of paint before its installation. Then, hollow space is generated in H-H joint after treating by water-swelling sheet, and that space can be used effectively. This paper proposes leachate control technologies using H-H joint interior space of SPSP cutoff walls. The possibility of those technologies and hydraulic conductivity of H-jointed SPSP with H-H joints are demonstrated by conducting the hydraulic conductivity test.展开更多
