Profit, we have to clear out the debris of in the hole.
At present, in steel-pipe pile work progress, remove steel-pipe pile in debris, using by the way of be artificial borehole cleaning,
This borehole cleaning mode, high labor intensive, inefficiency, borehole cleaning effect is undesirable, and during borehole cleaning, there is safety hidden
Suffer from.
Content of the invention
It is an object of the invention to solving drawbacks described above that prior art exists it is proposed that a kind of pile foundation construction stake bottom borehole cleaning
Construction method, it has the characteristics that low cost, efficiency high, simple to operate.
The present invention is to be realized using following technical scheme：A kind of construction method of pile foundation construction stake bottom borehole cleaning, including
Following steps：
The bottom of the outlet side of the appendix being connected with air delivery device and outlet pipe is connected；
Outlet pipe is put in mounted casing；
The water side of the water-supply-pipe being connected with water delivery device is put in casing；
Start air delivery device and water delivery device, until after no-sundries in casing, first making water delivery device quit work, finally making
Air delivery device quits work.
Preferably, the step bag bottom of the outlet side of the appendix being connected with air delivery device and outlet pipe being connected
Include, the outlet side of appendix is put in outlet pipe from the bottom of outlet pipe；By appendix together with outlet pipe colligation it is ensured that
The outlet side of appendix will not be deviate from from outlet pipe.
Preferably, outlet pipe is put into the step in mounted casing to include, outlet pipe is connected with loop wheel machine；Behaviour
Make loop wheel machine to put into outlet pipe in casing.
Preferably, when operation loop wheel machine puts into outlet pipe in casing, outlet pipe is vertically placed.
Preferably, outlet pipe bottom is located above the debris within casing.
Preferably, the water side of water-supply-pipe is located above the debris within casing.
Preferably, after starting air delivery device, persistently rock outlet pipe, until the debris in casing are discharged.
Preferably, air delivery device is the air compressor machine being provided that gases at high pressure, and water delivery device is to be provided that highly pressurised liquid
Centrifugal pump.
The invention has the beneficial effects as follows：
The present invention has little, the efficiency high of input, feature simple to operate, with respect to labor cleaning, with more safety, is
The smooth enforcement of piling construction provides guarantee.
Brief description
Fig. 1 is the structural representation of hole cleaning device；
In figure：1 air compressor machine, 2 appendix, 3 centrifugal pump, 4 water-supply-pipe, 5 outlet pipe 6 casing.
Specific embodiment
With reference to specific embodiments and the drawings, the present invention will be further described.
As shown in figure 1, in steel-pipe pile installation, carrying out setting of casing 6 first, casing 6 sets takes vibration hammer
Constructed, stop when cannot sinking to casing 6, then carry out borehole cleaning operation.
The borehole cleaning operation of the present invention adopts the construction method of pile foundation construction stake bottom borehole cleaning, comprises the following steps, first will be defeated
Trachea 2 is connected with air delivery device, and the bottom of the outlet side of appendix 2 and outlet pipe 5 connects, specifically, by giving vent to anger of appendix 2
End puts in outlet pipe 5 from the bottom of outlet pipe 5；By appendix 2 it is ensured that the giving vent to anger of appendix 2 together with outlet pipe 5 colligation
End will not be deviate from from outlet pipe 5.
Then outlet pipe 5 is connected with loop wheel machine, outlet pipe 5 is vertically put in casing 6 by operation loop wheel machine, and outlet pipe
5 bottoms are located above the internal debris of casing 6, leave certain gap, to ensure that debris can smoothly enter casing 6 and then row
Go out.Again the water side of the water-supply-pipe 4 being connected with water delivery device is put in casing 6, make the water side of water-supply-pipe 4 be located at casing 6
Above internal debris, with hovel every a small distance, to ensure scouring effect.The device of so whole borehole cleaning just arranges
Become.Preferably, wherein air delivery device is the air compressor machine 1 being provided that gases at high pressure, water delivery device be provided that highly pressurised liquid from
Heart pump 3.
Finally start air compressor machine 1 and centrifugal pump 3, until after no-sundries in casing 6, that is, after the no obvious silt of casing 6, first
So that water delivery device is quit work, after the water in casing is all discharged, so that air delivery device is quit work, whole borehole cleaning work
Complete.It should be strongly noted that after startup air delivery device, will persistently rock outlet pipe 5, until the debris in casing 6 are discharged,
Such that borehole cleaning is in hgher efficiency, the effect of borehole cleaning is even more ideal.
After borehole cleaning finishes, take out whole hole cleaning device, then using vibration hammer, steel pile casting is extracted, then carry out staking out work
Industry.
The present invention reduces the blast of venthole by air compressor machine aerofluxuss, makes the mouth of pipe form the side of blowout by the pressure of water
Method realizes borehole cleaning.Centrifugal pump extracting seawater is introduced in casing by water-supply-pipe and forms high-pressure spray, silt is rushed, by water outlet
Bank of tubes goes out, and meanwhile, water-supply-pipe need to supplement casing maritime interior waters, keeps water-head.Air compressor machine air vent passes through hose connection high pressure steel
Pipe enters near mouth under sand discharge pipe (i.e. outlet pipe), forms powerful draught head, silt is along pipe in the pipe of sand discharge pipe and outside pipe
It is rushed out outside stake.
Certainly, the above is only presently preferred embodiments of the present invention it is impossible to be considered for limiting to inventive embodiment
Scope.The present invention is also not limited to the example above, and those skilled in the art are in the essential scope of the present invention
The impartial change made and improvement etc., all should belong to patent covering scope of the present invention.
