Abstract
PURPOSE: To prevent effectively the liquefaction of the sandy ground apt to occur at the time of earthquake, by forming drain piles making use of such space forming materials as crushed stones by means of nonvibration and nonpressure works.
CONSTITUTION: In order to prevent the sandy ground from liquefaction, the drain piles 2 making use of such space forming materials as crushed stones 1 are arranged in the ground 3 with proper dispositions, and the excessive water pressures apt to occur at the time of earthquake are absorbed through the piles 2. These piles 2 are formed by means of nonvibration and nonpressure works, using for instance the Benoto-machine A. That is to say, the boring hole 4 is dug vertically while digging out the sands in the cylindrical casing a1 with hammer-grab a2 and lowering gradually the casing a1. When the casing hole 4 reaches the desired depth, it is filled with the materials 1. By puling up the casing a1, the pile 2 is formed.
