摘要： PROBLEM TO BE SOLVED: To provide an air injection device to sandy ground and a sandy ground liquefaction preventing engineering method, preventing clogging of an air injection hole to take stable liquefaction preventing measure in injecting the air through an air injection pipe intruded into the sandy ground saturated with water to prevent liquefaction.
SOLUTION: In intruding the air injection pipe 2 into the sandy ground saturated with water, water W supplied from a water tank 9 is naturally delivered through the air injection pipe 2 and discharged from the air injection hole 4, and also water in the sandy ground is caused to flow into a void part 7a constituting a muddy water storing part 7 of a tip member 6 connected to the tip of the air injection pipe 2 through a communicating hole 7b, whereby excessive pore water pressure generated by intruding the pipe is dissipated to avoid fine grains and foreign matter in the sandy ground from entering the air injection hole 4.

摘要： PROBLEM TO BE SOLVED: To provide a method for measuring the degree of saturation of ground, which is employed for a ground liquefaction prevention method for unsaturation degree of the ground by injecting air into the ground, which makes the degree of the saturation of the whole prescribed ground measured in a two-dimensional or three-dimensional manner, and which enables the degree of the saturation of the ground to be accurately measured by a combination of two types of measuring methods.
SOLUTION: The degree of the saturation of the ground is measured by measuring a dielectric constant of the ground by means of a dielectric constant measuring device. Additionally, the degree of the saturation of the ground is measured by measuring a rate of change of specific resistance of the ground by means of a specific resistance tomography measuring device. A correlation between the degrees of the saturation of the ground is derived from the result of measurement by the specific resistance tomography measuring device and that of measurement by the dielectric constant measuring device. The result of the measurement by the specific resistance tomography measuring device is calibrated on the basis of that of the measurement by the dielectric constant measuring device.

摘要： PROBLEM TO BE SOLVED: To provide a liquefaction prevention method for sandy ground and a structure for air injection which prevent the air injected through a pipe buried in an installation hole of the sandy ground, which is saturated with water, from leaking through the gap formed around the outer peripheral surface of the pipe and around the inner peripheral surface of the installation hole so that the degree of saturation may be lowered by the injected air.
SOLUTION: The pipe 3 is internally inserted into a casing pipe inscribed to the installation hole 1 formed in the sandy ground saturated with the water, and silica sand S is filled between the casing pipe and the pipe 3 to the position where an air injection hole 4 of the pipe 3 is buried, so that a filter layer 5 may be formed. Next, an airtight filling material is filled to form an airtight layer 6. Then, after backfilling of the part above the airtight layer 6 and pulling out the casing pipe, the air A from an air supplying device 9 is injected into the ground from the air injection hole 4. When the gap is formed around the outer peripheral surface of the pipe 3 and around the inner peripheral surface of the installation hole, the airtight layer 6 prevents the air A from leaking to the ground surface.
