Ｎ値はJIS Ａ−1219の試験法により算出した。 The N value was calculated according to the test method of JIS A-1219.
回転ローラ４１〜４２のみによる打込みでは、
打込みバー９がグラフ上にＡ点で示すＮ値が15の
地盤に達するとローラ４１〜４２が空回りして打
込み不能となつた。 In driving using only the rotating rollers 41 to 42,
When the driving bar 9 reached the ground where the N value indicated by point A on the graph was 15, the rollers 41 to 42 idled and driving became impossible.
補助打込み装置５を併用して打込みを行なつた
ところ、Ｎ値15の地盤を貫通し、Ｂ点で示すＮ値
25の地盤をも破つた。 When driving was performed using the auxiliary driving device 5, it penetrated the ground with an N value of 15, and the N value shown at point B was reached.
It also broke 25 levels of ground.
この時のローラ駆動用の油圧モータ４４の作動

ると約12tになる。昇降用油圧シリンダ６の圧力
は100Kg／cm2を示し、これを打込み力に換算する
と２基の昇降用シリンダ６で約3tになる。 At this time, the discharge pressure of the hydraulic oil from the hydraulic motor 44 for driving the roller is 270 kg/cm 2 , which is approximately 12 tons when converted into driving pressure. The pressure of the lifting hydraulic cylinders 6 is 100 Kg/cm 2 , and when converted into driving force, the two lifting cylinders 6 produce approximately 3 tons.
即ち、ローラによる打込み力と昇降用シリンダ
による打込み力を加えた約15tの打込み力でＮ値
25の地盤を突破出来ることが判つた。 In other words, the N value is approximately 15t, which is the sum of the driving force from the roller and the driving force from the lifting cylinder.
It turned out that it was possible to break through 25 levels of ground.
尚、実施例では主打込み装置４の上流側に補助
打込み装置５を配備したが、逆の配置に出来るの
