【課題を解決するための手段】
本発明は、杭本体の下端に補強鋼を固着し、杭本体と補強鋼にわたって当て板を、その下端が補強鋼の下端より上方に位置するごとく取付けた岩盤への杭打用杭および、杭本体の下端に補強鋼を固着し、補強鋼のフランジ同士又はフランジとウエブを夫々連結するごとく補強部材を、夫々の補強鋼の下端より上方に取付けた岩盤への杭打用杭からなり、さらに杭本体と導水パイプとからなり、該導水パイプは該杭本体に対して上下方向に移動可能で、かつ隣接して該杭本体に取付けられ、該杭本体の先端を振動杭打機により岩盤に打ちつけて岩盤を破砕し、この破砕した岩石を該導水パイプからの噴射水で排除することにより岩盤中に杭を打込む岩盤への杭打工法において、杭本体の下端に補強鋼を固着し、杭本体と補強鋼にわたって当て板を、その下端が補強鋼の下端より上方に位置するごとく取付けた岩盤への杭打工法および杭本体と導水パイプとからなり、該導水パイプは該杭本体に対して上下方向に移動可能で、かつ隣接して該杭本体に取付けられ、該杭本体の先端を振動杭打機により岩盤に打ちつけて岩盤を破砕し、この破砕した岩石を該導水パイプからの噴射水で排除することにより岩盤中に杭を打込む岩盤への杭打工法において、杭本体の下端に補強鋼を固着し、補強鋼のフランジ同士又はフランジとウエブを夫々連結するごとく補強部材を、夫々の補強鋼の下端より上方に取付けた岩盤への杭打工法からなる。 [0016]
[Means for Solving the Problems]
In the present invention , a pile driving pile and a pile are mounted on a bedrock in which a reinforcing steel is fixed to the lower end of a pile main body and a caul plate is installed over the pile main body and the reinforcing steel with its lower end positioned above the lower end It consists of piles for pilings to the rock, with reinforcement members fixed at the lower end of the main body and reinforcement members to connect the flanges of the reinforcement steel or the flanges and the web, respectively, above the lower ends of the respective reinforcement steels Consisting of a pile body and a water pipe, the water pipe is vertically movable with respect to the pile body and is adjacently attached to the pile body, and the tip of the pile body is placed on a bedrock by a vibrating pile driver. In the piling method to the bedrock that drives a pile into the bedrock by fixing the reinforcing steel at the lower end of the pile body, by striking and breaking the bedrock and removing the crushed rock with the water jetted from the water transmission pipe, Battening plate across pile body and reinforcing steel The pile driving method for a bedrock mounted so that the lower end thereof is positioned above the lower end of the reinforcing steel, and a pile body and a water conveyance pipe, the water conveyance pipe is vertically movable with respect to the pile body, Adjacently attached to the pile body, the tip of the pile body is struck against the bedrock with a vibrating pile driver to break up the bedrock, and the crushed rock is expelled by the water jetted from the water transmission pipe into the bedrock In the pile driving method to the rock that drives the pile, the reinforcing members are fixed to the lower end of the pile main body and the flanges of the reinforcing steel or the flanges and the web are connected, respectively, above the lower ends of the respective reinforcing steels. It consists of pile driving method to the attached rock mass.
