    • PURPOSE: A pressurized grouting method using a non-displacement self-drilled screw pile is provided to enable simple ground reinforcement work with low costs since pressurized grouting is performed without separate packers. CONSTITUTION: A pressurized grouting method using a non-displacement self-drilled screw pile comprises the following steps. A non-displacement screw wing is formed on the outer surface of the front end of a hollow body, and a screw pile formed with a through-hole on the front end of the hollow body is prepared. A screw pile is rotated and press-fitted into the ground for first insertion until the front end formed with the through-hole is completely inserted into the ground. While the inside of the hollow body of the screw pile is compressed by air pressure or water pressure, the screw pile is rotated and moved forward for second insertion. Grouting fluid is injected into the inside of the hollow body of the screw pile so the screw pile is mounted on the ground(S13).
    • 目的:提供使用非排量自钻螺丝桩的加压灌浆方法,以便在没有单独的封隔器的情况下执行加压灌浆,从而能够以低成本进行简单的地面加固工作。 构成:使用非排量自钻螺杆的加压灌浆方法包括以下步骤。 在中空体的前端的外表面上形成有非位移螺旋翼,并且准备在中空体的前端形成有通孔的螺旋桩。 旋转螺杆堆并压入地面进行首次插入,直到形成有通孔的前端完全插入地面。 当螺杆桩的中空体的内部被空气压力或水压力压缩时,螺杆堆被旋转并向前移动以进行第二次插入。 将注浆液注入螺杆桩的中空体的内部,使螺杆桩安装在地面上(S13)。
