摘要： PROBLEM TO BE SOLVED: To provide a sheet pile having a drainage function, which has a long- term liquefaction inhibition function and excellent strength and rigidity. SOLUTION: Hollow drainage canals 5 are formed between a ribbed plate 13a and a sheet pile body 1 by utilizing the recessed section of the sheet pile body 1. In the ribbed plate 13a, a proper number of vertical ribs 15 are formed to the plate 13a in the longitudinal direction of the sheet pile, rigidity to the horizontal pressure of a ground at the time of the execution of the sheet pile and the time of usage is ensured, and deflection in the horizontal direction is prevented. A large number of holes 3 are bored to the plate section of the ribbed plate 13a, and a filter 4 for obviating the penetration of soil and sand is installed. The size of the cross sections of the drainage canals 5 is determined in consideration of the characteristics, drainage resistance, etc. of a liquefaction ground.

摘要： PURPOSE:To promote cut-off efficiency and durability by projecting bedrock side steel plates and inside space side steel plates between adjacent segments from a segment body opposite to them to join in a joint section of a steel concrete composite segment. CONSTITUTION:Tunnel bedrock side steel plates 8, inside space side steel plates 9 and segment side plates 17 are projected from segment body ends 20, the projection lengths of the bedrock side steel plates 8 and segment side plates 17 are longer than those of the inside space side steel plates 9. After that, joint boxes 10 opened to a tunnel inside space are provided to positions of the segment body ends 20, and after bolts 21 are inserted into their bolt insertion hole 14 to assemble temporarily adjacent segments, a joining section 11 of the bedrock side steel plates 8 is connected. A joining plate 18 is laid between the inside space side plates 9, joining sections 12 of the joining plate 18 and inside space side steel plates are welded, and mortar is poured from a grout filling hole 13 to form a joint section.

摘要： PURPOSE:To simplify a construction process, decrease the welding residual stress and improve the fatigue strength and to improve the appearance by connecting plural steel members to each other by cross girders to form a main girder and fixing a reinforced concrete floor plate on the main girder. CONSTITUTION:The upper edges of a pair of steel materials 11 having a U-shaped section are butted, welded and joined 12 to form one steel member 10 where upper and lower flange members 111 and right and left web portions 112 are connected to each other. Subsequently, plural brace blocks 130 are welded to the upper flange portion 110. A reinforced concrete floor plate 51 is combined with the main girder 52a through the brace blocks 130. Thus, a construction process can be simplified, the welding residual stress of a main girder can be decreased and further fatigue strength and the appearance can be improved.

摘要： PURPOSE:To prevent liquefaction by providing a draining member having a large number of openings and a filter for preventing the earth and sand from entering the insides of them to a specific section along a sheet pile body at least to the single side of the sheet pile. CONSTITUTION:An earth and sand intrusion preventive material formed by putting a metallic or synthetic resin net 12 and a filter 11 together on the head of a channel steel 2 for preventing the earth and sand from intrusion is mounted to a drainage ditch 5 consisting of the channel steel 2 and a sheet pile body 1. A tip protective plate 10 is mounted to the lower end suction of the channel steel 2 in order to prevent the intrusion of the earth and sand. In addition, the filter 4 is loaded to the side of the drainage ditch 5 of a draining member in case a large number of parts of holes 3 or holes 3 are bored. According to the constitution, the liquefaction of the ground in the vicinity of the sheet pile is suppressed and, at the same time, the resistance to the lateral flow or slippage can also be made.
