1 中掘工法埋入式桩1 1 基本原理中掘工法 (可称桩中钻孔法 )埋入式桩 ,是在开口的ＰＣ管桩、ＰＨＣ管桩及钢管桩等的中空部插入专用钻机 ,边钻孔取土边将桩埋入土层中 ;为增大其桩侧摩阻力 ,可采取边注入水泥浆等边钻孔边将桩埋入土层中 ,由水泥浆充填桩周间隙 ;为增大其桩?
1 excavation method embedded pile 1 1 basic principle digging method (which can be called the pile drilling method) buried pile, is inserted in the opening of the PC pipe pile, PHC pipe pile and hollow parts such as steel pipe dedicated In order to increase the lateral friction of the pile, the pile can be embedded into the soil layer while injecting the slurry into the soil layer while injecting the slurry into the soil layer. To increase its stake?
