If the stake of design is long, it is desirable to many prefabricated tubular piles are applied in combination.Pile tube is usually tubular structure at present, and two ends are wrapped
Being wrapped with steel hoop, steel hoop flush, can only carry out as outside weldings during welding, bonding strength is poor.This connected mode is only
Being the link on surface, bonding strength is poor, there is potential safety hazard.It is not good at additionally, due to construction management, after welding completes, reaches not
Require or do not reach time interval to welding quality and continue with piling work, pile breaking phenomenon easily occurs.
Summary of the invention
It is an object of the invention to provide a kind of prefabricated tubular pile quick connecting method, this pile extension method is not extending the pile extension time
Under premise, substantially increase the bonding strength of prefabricated tubular pile, effectively prevent the pile breaking phenomenon occurred during piling.
The technical solution used in the present invention is as follows:
A kind of prefabricated pipe stake, its cross section is circular ring section, is provided with therein and the manhole of pile tube coaxial line, prefabricated
The two ends of pile tube are provided with symmetrical and form welding skylight hole groove when pile extension.
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 the most corresponding between adjacent prefabricated tubular pile forms welding skylight hole.
Described welding skylight hole is by the welding closure of arc H profile steel plate.
Described prefabricated tubular pile is internal after pile extension completes carries out injecting treatment.
The concrete method of attachment of said apparatus is as follows:
Step 1, require true fixed pile according to design after be pressed into below ground through the first root canal pile, more than ground, reserved 1m is left
The right side carries out pile extension；
Step 2, lifting the second root canal pile, slip casting in anchor hole, by the second root canal pile and the dowel of the first root canal pile and anchor hole anchor
It is solidly connected, and ensures perpendicularity；
Step 3, outer surface to upper and lower two root canal piles weld；
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 closure welding skylight；
Step 6, carry out next step piling work；
Step 7, repeat the above steps 1-6, until reaching designed elevation；
Step 8, finally carry out the internal grouting treatment of pile tube.
Beneficial effects of the present invention is as follows:
This prefabricated circular pile tube, upper and lower two ends are the most fluted, formed and set on welding skylight, and the ring surface at prefabricated tubular pile top
There is anchor hole, reserved anchor bar on the ring surface of bottom.Being attached by dowel and anchor hole between pile tube up and down, outer surface leads to
Crossing and be welded to connect, inner surface carries out interior welds by welding skylight, it is ensured that weld strength, greatly reduces the appearance of broken pile.
