The height of described projection is less than the degree of depth with groove.
Described prefabricated tubular pile two ends projection and groove are wrapped up by steel hoop.
Between adjacent prefabricated tubular pile, Jointing is passed through in its outer ring; Its inner ring carries out interior welds by skylight hole.
Described prefabricated tubular pile tube wall is connected by not through four bolts;
The welding skylight hole of described prefabricated tubular pile is finally by H profile steel plate welding shutoff;
Described welding skylight hole is by arc H profile steel plate welding shutoff.
Injecting treatment is carried out in described prefabricated tubular pile inside after pile extension completes.
The concrete method of attachment of said apparatus is as follows:
Step 1, according to after the true fixed pile of designing requirement, the first root canal pile is pressed into below ground, more than ground, reserved about 1m carries out pile extension;
Step 2, lift the second root canal pile, make the groove of the second root canal pile and the first root canal pile and protruding grafting, and ensure verticality;
Step 3, the external surface of employing electric welding to upper and lower two root canal piles weld;
Step 4, welding skylight opening that is protruding by two root canal pile stake ends and groove formation carry out pile tube interior welds;
Step 5, erection bolt, complete the connection work of two root canal piles;
Step 6, employing arc H steel plate carry out shutoff to welding skylight opening;
Step 7, carry out next step piling work;
Step 8, repetition step 1-7, until reach design elevation;
Step 9, finally carry out the inner grouting treatment of pile tube.
Beneficial effect of the present invention is as follows:
This prefabricated square pile tube, upper and lower two ends have projection and groove respectively, and projection and groove can form welding skylight.The prefabricated tubular pile of this structure, not only can surface soldered, and can carry out interior welds and be connected with bolt, ensure that weld strength, greatly reduces the appearance of broken pile.
