(2) 〈NOTE〉 “NS-SP” used in this brochure are Nippon Steel & Sumitomo Metal’s internal product codes for steel sheet pile products.. Features. Foreword. A Wide Selection of Shapes and Types. The steel sheet piles of Nippon Steel & Sumitomo Metal are used in many fields (port and harbor structures, river revetment, earth retention and cofferdams) and have acquired high market acceptance due to their excellent product quality and to construction efficiencies that derive from their use. Nippon Steel & Sumitomo Metal, drawing on a wealth of rolling, fabrication and application and further adding to the superb properties of its sheet pile, has recently developed various new products and construction methods in this field, which have also won for the company a high reputation. Based on an accumulation of technical expertise, Nippon Steel & Sumitomo Metal has developed and placed on the market two versions (NSP-10H and NSP-25H) of a new line of sheet piles:”hat-type steel sheet piles 900.” Nippon Steel & Sumitomo Metal will continue its efforts to develop novel products that bring the properties of sheet piles into full play and to respond to more stringent and diversifying user needs in the future.. Sheet pile is available in a wide range of selection moduli per meter of pile wall width, ranging from 874 to 8750 cm³. This allows selection of the most economical type of sheet pile to suit the design requirements and the intended construction method.. Superb Drivability and Water tightness Clearances of joints are tight enough to ensure excellent drivability as well as water tightness of sheet pile wall.. Contents.

This cornersection sheet pile does not require welding, thus it greatly reduces weight. ● For assembly, the conventional cast equipment can be used as-is. ●In particular, Larssen sheet piling has been adopted as a base for the shape of corner joints, in order to prevent detachment, and therefore, particularly, joint performance such as fitment and repetition endurance is excellent. ● Corner sheet pile is a newly developed type produced by rolling to replace the conventional T-shape corner sheet pile produced by welding. Thus it eliminates the need for welding and other fabrication processes, and is far lighter in weight.. ■ Shapes NS-SP-Ⅳ. NS-SP-ⅤL. NS-SP-ⅥL. NS-SP-CⅢ、NS-SP-CⅣ Corner section sheet pile.

(12) Driving Method. ■ Press-in method Sheet piles are pressed-in using hydraulic mechanism by grasping the middle place of sheet pile while taking. ■ Vibration method. reaction by holding driven piles. Driving machine is compact, and need not crane, though it needs crane. Sheet piles are driven into the ground by transferring to them up-and-down vibratory forces generated by vibratory hammer. Because percussion force is not used, pile head is not injured, driving efficiency is high and, is useful for both driving and pulling piles.. separately for hanging sheet piles. It is applicable to the driving conditions such as narrow places and low clearance places. It is also possible to drive piles in conditions of low noise and low vibration. When ground is so hard that driving is difficult by using only pressing machine, it is useful to use water jet cutter together.. Press-in machine for hat-type sheet pile 900. Over view.
