Illustrate the present invention, but is not intended to limit the scope of the invention.
Embodiment one:
The assembly of the tubular pole designed in the present embodiment is greater than 10m, it is therefore desirable to carry out pile extension to tubular pole, the tubular pole of bottom has been beaten
Enter in ground, and the verticality of the tubular pole of bottom meets the requirements, is welded at the top of the bottom of the second root canal pile and bottom tubular pole
Pile extension, but find that the second root canal pile generates inclination after making a call to the second root canal pile.
Verticality correction is carried out to the second root canal pile referring to attached antidote shown in FIG. 1.
Referring to shown in attached drawing 2, measured using verticality of the verticality measurement device to inclination tubular pole 1, after measurement
Verticality to the inclination tubular pole 1 is greater than 0.5%L, is unsatisfactory for the requirement of tube pile construction specification, thus need to the inclination tubular pole 1 into

Step 2: referring to shown in attached drawing 1 and attached drawing 4, with the drill bit point of km drilling machine, insertion is tilted in tubular pole 1 several times,
Due to tipping tube turn 1 be it is inclined, the drill bit of km drilling machine is vertical, therefore the depth that the drill bit of km drilling machine is squeezed into every time is not
Preferably too deep, the too deep drill bit that will lead to breaks through inclination tubular pole 1, and while drill bit is inserted into, drill bit pours into soil to inside inclination tubular pole 1
5 loosen the soil, and the every insertion of the drill bit of km drilling machine is primary, and the opposite direction level with crane along inclination 1 inclined direction of tubular pole pushes away
Dynamic km drilling machine, due to loosening the soil area 2 and part pours into soil 5 by processing of loosening the soil, correction tilt it is relatively labor-saving when tubular pole 1, by
Successive step tilts the verticality of tubular pole 1, until inclination tubular pole 1 is completely vertical, the speed of correction should not be too fast, avoids correction excessive
And lead to tilt tubular pole 1 to other side inclination, and in entire correcting process, pass through verticality measurement device and cooperates inspection in real time
The verticality for surveying the inclination tubular pole 1 can just stop correcting when verticality is less than 0.5%L.
Step 3: referring to shown in attached drawing 1 and attached drawing 5, run-off the straight during being driven piles due to inclination tubular pole 1 causes to tilt
The pad of tubular pole 1 and the tubular pole of its underpart disconnects, and gap occurs between upper and lower two root canal pile, soil around pile can enter from gap
Into the cavity at tubular pole center, it is centrally formed in tubular pole and pours into soil 5, therefore after tilting tubular pole correction, it is cleared up using small-sized digging machine
Whole in inclination tubular pole 1 pours into soil 5 and pours into soil 5 to correct the part for the tubular pole top position that hypsokinesis inclined tube turns lower section, until
The cleaning face for pouring into soil 5 is located at correction 1 bottom of rear-inclined tubular pole or less position 2m (position cleaned up is for putting steel reinforcement cage 3
Two root canal piles up and down are connected with concrete perfusion 5, therefore the cleaning face for pouring into soil has to be lower than correction 1 bottom of rear-inclined tubular pole,
Again because becoming larger with depth, the cleaning difficulty for pouring into soil 5 is also bigger, empty completely pour into soil 5 project amount it is too big, the later period is mixed
The usage amount of solidifying soil and reinforcing bar also can be very big, causes to waste, and comprehensively considers cleaning to correction 1 bottom of rear-inclined tubular pole or less 2m most
It is suitable).
Step 4: referring to shown in attached drawing 1 and attached drawing 6, steel reinforcement cage 3, steel reinforcement cage are put into inside the tubular pole of 1 lower section of inclination tubular pole

The top in face, then one side penetration concrete 4, one side hoisting grouting pipe, the inclination tubular pole behind the surface of concrete 4 and correction
1 stake top flushes, and stops tank concrete, extracts Grouting Pipe, last curing concrete 5.The armored concrete part is instead of original
Two up and down are improved its role is to reconnect two root canal piles up and down in the part being first welded to connect between two root canal piles up and down
The synergistic effect ability of tubular pole.
Step 6: it referring to shown in attached drawing 1, is loosened the soil the soil in area 2 using the compacting of sandbag static pressure.
Embodiment two:
In conjunction with shown in attached drawing 8, when the assembly of tubular pole is less than 10m, or the first root canal pile is made a call in the case where needing pile extension and is just gone out
When the problem of existing tubular pole inclination, corrected by following construction procedure.
Step 1: it referring to shown in attached drawing 9, is loosened the soil, is formed to the soil away from inclination 1 inclined direction of tubular pole using drilling machine
It loosens the soil area 2, the driving depth that the depth in area 2 of loosening the soil must deeply with the inclination tubular pole 1.
Step 2: referring to shown in attached drawing 10, with the drill bit point of km drilling machine, insertion is tilted in tubular pole 1 several times, due to inclining
Inclined tube turn 1 be it is inclined, the drill bit of km drilling machine is vertical, therefore the depth that the drill bit of km drilling machine is squeezed into every time should not mistake
Deep, the too deep drill bit that will lead to breaks through inclination tubular pole 1, while drill bit is inserted into, drill bit to inside inclination tubular pole 1 pour into native 5 into
Row loosens the soil, and the every insertion of the drill bit of km drilling machine is primary, with crane along the opposite direction Level Promoting thousand of inclination 1 inclined direction of tubular pole
Rice drilling machine, due to loosening the soil area 2 and part pours into soil 5 by loosening the soil processing, correction tilts relatively labor-saving when tubular pole 1, gradually adjusts
The verticality of whole inclination tubular pole 1, until inclination tubular pole 1 is completely vertical, the speed of correction should not be too fast, avoids correction excessive and leads
It causes inclination tubular pole 1 to tilt to the other side, and in entire correcting process, cooperates real-time detection should by verticality measurement device
The verticality for tilting tubular pole 1 can just stop correcting when verticality is less than 0.5%L.
Step 3: it is loosened the soil the soil in area 2 using the compacting of sandbag static pressure.
Due in the tubular pole of work order root canal pile or bottom, the problem of there is no the welding of upper and lower tubular pole, therefore with implementation
Example one is compared, and the present embodiment is not necessarily to 5 carry out emptying processing to the soil that pours into inside tubular pole, without being put into steel reinforcement cage 3 and be perfused
Concrete 4.
It describes the invention in detail in conjunction with the embodiments above, but the content is only preferable implementation of the invention
Example, should not be considered as limiting the scope of the invention.It is all according to all the changes and improvements made by the present patent application range
Deng should all still fall within patent covering scope of the invention.
