CORE MATERIAL FOR EARTH RETAINING WALL AND UPPER CORE MATERIAL REMOVING METHOD
PROBLEM TO BE SOLVED: To allow an upper core material 12 of a core material 5 built in an earth retaining wall to be removed by releasing connection between the upper core material and a lower core material 11.SOLUTION: A connection means 13 between a lower core material (H-shaped steel) 11 and an upper core material (H-shaped steel ) 12 comprises: a first to fourth splice plates 21 to 24, which butt against outer surfaces and inner surfaces of drilling side flanges 11a, 12a and inner surfaces and outer surfaces of natural ground side flanges 11b, 12b, respectively; a first fixing means 25, which fixes lower parts of the splice plates 21 to 24 and the lower core material 11; and a second fixing means 26, which fixes upper parts of the splice plates 21 to 24 and the upper core material 12. The second fixing means 26 includes a long bolt 35, which penetrates the first splice plate 21, the drilling side flange 12a, the second splice plate 22, the third splice plate 23, the natural ground side flange 12b and the fourth splice plate 24 from the drilling side. Only the second splice plate 22 has a screw part 36 that screws with the long bolt 35.SELECTED DRAWING: Figure 3
【課題】 土留め壁に建て込まれる芯材５において、下側芯材１１との連結を解除して上側芯材１２を撤去可能とする。【解決手段】 下側芯材（Ｈ形鋼）１１と上側芯材（Ｈ形鋼）１２との連結手段１３は、掘削側フランジ１１ａ、１２ａの外面、及び内面、地山側フランジ１１ｂ、１２ｂの内面、及び外面にそれぞれ当接する第１〜第４の添接板２１〜２４と、前記添接板２１〜２４の下部と下側芯材１１とを固定する第１の固定手段２５と、前記添接板２１〜２４の上部と上側芯材１２とを固定する第２の固定手段２６と、を含む。前記第２の固定手段２６は、掘削側から、第１の添接板２１、掘削側フランジ１２ａ、第２の添接板２２、第３の添接板２３、地山側フランジ１２ｂ、及び、第４の添接板２４を貫通する長ボルト３５を含む。ここで、第２の添接板２２にのみ、長ボルト３５と螺合するねじ部３６がある。【選択図】 図３
