摘要
拖式混凝土输送泵式水下灌注方法是结合了超流态混凝土灌注法和导管灌注法的特点,采用TL型反循环钻机成孔,下钢筋笼,再利用泵送力代替一次投入混凝土产生的冲击力排开孔内浆液,实现传统的水下灌注的目的。
underwater infusion method of towed concrete pump is a combination of super-fluid concrete perfusion and catheter perfusion. It used TL-type reverse circulation drilling rig to drill a hole, filled into the reinforcement cage, and pumned out the serous.
