utility model object
The purpose of this utility model is to provide a kind of prefabricated tubular pile quick connecting method, and this pile extension method, under the prerequisite not extending the pile extension time, substantially increases the bonding strength of prefabricated tubular pile, effectively prevent the pile breaking phenomenon occurred in piling process.
The technical solution adopted in the utility model is as follows:
A kind of prefabricated pipe stake, its cross section is circular ring section, is provided with the manhole with pile tube coaxial line therein, is provided with symmetrical and for forming welding skylight hole groove during pile extension at the two ends of prefabricated tubular pile.
The ring surface at described prefabricated tubular pile top is provided with anchor hole, reserved anchor bar on the ring surface of bottom.
The top anchor hole that the prefabricated tubular pile being positioned at upper strata inserts lower floor's prefabricated tubular pile by the anchor bar of bottom carries out anchor connection.
Described prefabricated tubular pile two ends groove is all 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.
Groove mutually corresponding between adjacent prefabricated tubular pile forms welding skylight hole.
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, be pressed into below ground according to after the true fixed pile of designing requirement through the first root canal pile, more than ground, reserved about 1m carries out pile extension;
Step 2, lift the second root canal pile, slip casting in anchor hole, by the dowel of the second root canal pile and the first root canal pile and anchor hole anchor connection, and ensure verticality;
Step 3, the external surface of upper and lower two root canal piles to be welded;
Step 4, by two root canal pile stake end grooves formed welding skylight opening carry out pile tube interior welds;
Step 5, employing circular arc H profile steel plate shutoff welding skylight;
Step 6, carry out next step piling work;
Step 7, repetition above-mentioned steps 1-6, until reach design elevation;
Step 8, finally carry out the inner grouting treatment of pile tube.
the beneficial effects of the utility model are as follows:
This prefabricated circular pile tube, upper and lower two ends are all fluted, form welding skylight, and the ring surface at prefabricated tubular pile top are provided with anchor hole, reserved anchor bar on the ring surface of bottom.Be connected with anchor hole by dowel between upper and lower pile tube, external surface is by being welded to connect, and inner surface carries out interior welds by welding skylight, ensure that weld strength, greatly reduces the appearance of broken pile.
