Embodiment Construction
[0025] The construction method of the immersed tube type non-crowding underground diaphragm wall, the construction steps are as follows:
[0026] 1) Place the solid concrete pile shoe 7 on the designated pile position;
[0027] 2) Use the pile driver equipment 1 to lift the rectangular pipe sinker 5, and set the rectangular pipe sinker 5 with the soil discharge pipes 6 on both sides on the solid concrete pile shoe 7;
[0028] 3) Hit the holder 3 on the top of the rectangular pipe sinker 5 with a high-frequency hydraulic vibrating hammer 2, vibrate in turn into a group of four rectangular pipe sinkers that are adjacent to each other, and the soil passes through the discharge pipes on both sides of the rectangular pipe sinker 6 The bottom port enters the soil discharge pipe 6, and is discharged to the ground from the mud outlet 4 on the top of the soil discharge pipe 6;
[0029] 4) Place a reinforcement cage in the rectangular immersed tube;
[0030] 5) Pour concrete into the ...
