Description
Technical field:
The present invention relates to a kind of long deep hole pile base construction method, particularly a kind of job practices of extra-deep hole drilling and fast slag tapping.
Background technology:
Along with the continuous progress of deep water bridge design and construction level, the Pile Foundations Design of the reservoir area deep water bridge of lithostratigraphy, construction are also more and more.Because the super depth of water, the length (drift of pile foundation) of drilled pile in water is long, therefore the embedding rock of pile foundation is very dark, the boring method of domestic employing remains the method for gravity jump bit pore-forming, the scum silica frost method of slagging tap and all adopting direct circulation of Churn drill pore-forming, mud by big proportion is rock particles floating aperture of taking at the bottom of the hole, remove boring mud by filtering-depositing, but because the hole is crossed dark and mud balance is bigger, the flow velocity of mud is very slow, the poor effect that scum silica frost removes slag directly causes speed of fulfiling hole to reduce (even it is also not obvious to increase the slush pump effect).
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art; and provide a kind of job practices of extra-deep hole drilling and fast slag tapping; this method improved the speed of slagging tap, reduced energy consumption, improved mud utilization rate, improve execution conditions, protected environment.
As above design, technical scheme of the present invention is: a kind of job practices of extra-deep hole drilling and fast slag tapping is characterized in that: carry out according to the following step:
(1) some steel pipes is coupled together by flange;
(2) the coxopodite welding of the steel pipe after connection is used to collect the bell of sediment, and connects high pressure rubber hose on coxopodite steel pipe;
(3) welding mud veclamation case on drilling platform, in the casing with demarcation strip be separated into mud sediment, separator box and in establish the mud agitator tank of agitator, in the mud agitator tank, put into the pulping agent; Above casing, tilt to place sieve;
(4) tail end of steel pipe is reached on the sieve of mud veclamation case top, high pressure rubber hose is connected on the air compressor machine;
(5) connect according to the degree of depth in hole peace and transfer steel pipe, transfer high pressure rubber hose simultaneously, until near the bottom, hole, steel pipe hangs with the hoist engine on the percussive drill, open the air valve of the air compressor machine that is connected with high pressure rubber hose, make pressure-air arrive the steel pipe of bottom, hole along high pressure rubber hose, rise rapidly along steel pipe afterwards, mud in the steel pipe is blown out boring, deliver to the sieve place of mud veclamation case top, the slag of big particle diameter directly is separated to outside the case, the sediment of small particle diameter is the process precipitation in the mud veclamation case, enter into after the separation and carry out secondary preparation mud in the mud agitator tank, directly be back to the hole after mud is qualified and carry out slurries and replenish, keep the head pressure of mud;
(6) when this slag tap finish after, it is out-of-blast to close the air compressor machine air valve, promotes steel pipe, utilizes pipe clamp the steel pipe card to be placed on the limit portion in hole;
(7) tup is put into the hole, begin boring once more, the construction of boring is finished in circulation successively.
The height of above-mentioned demarcation strip is lower than the height of branch cell.
Above-mentioned sieve props up into 30 ° of angles with dividing cell.
The present invention has following advantage and good effect: (1) has reduced the mechanical output of changing slurry, removing slag; (2) can under the prerequisite that keeps big mud balance, improve the efficient of slagging tap; (3) improved the mud utilization rate, the natural environment of protection job site has well satisfied environmental requirement; (4) facility are simple and easy easily makes, and building-site just can be made, easy construction; (5) scope of Shi Yonging is wide, the boring of difficulty so long as deep hole is slagged tap, and all available this equipment is auxiliary slags tap.

The specific embodiment:
A kind of job practices of extra-deep hole drilling and fast slag tapping is characterized in that: carry out according to the following step:
(1) earlier at long 4000mm, the flange steel plate 7 of the common steel pipe 1 of slagging tap of diameter 150mm (wall thickness 2mm) termination welding wall thickness 10mm diameter 210mm is used for the spreading steel pipe of slagging tap, and sticks on sealed rubber plate 9 between the flange, prevent gas leakage, spillage, connect triangle floor 10 on the flange
(2) at the coxopodite welding bell of the steel pipe of slagging tap, conical mouthful of diameter 200mm, height 150mm is used to collect sediment; At the slag tap little steel pipe mouthpiece of the high local weld diameter 40mm of the bottom 500mm of steel pipe of distance coxopodite, can connect the high pressure rubber hose 2 of tying up internal diameter 40mm.
(3) the mud veclamation case 6 of the steel plate 4m*6m*2m of welding (height) of usefulness 5mm, the separation steel plate 13 of two high 1.8m of welding in the middle of case, the steel case is divided into the mud agitator tank of establishing agitator 12 in two mud sediments, separator box and one, in the mud agitator tank, puts into the pulping agent.Place the reciprocating sieve 14 that reinforcing bar is welded into above chest, sieve aperture spacing 10mm*10mm props up into 30 ° slope with reciprocating sieve, and reciprocating sieve connects eccentric shaking motor 15, disposes so that the slag stone of big particle diameter is directly fallen on the outer platform of case.
(4) tail end of the steel pipe of slagging tap is reached on the reciprocating sieve of mud veclamation case top, and high pressure rubber hose is connected on the air compressor machine 4.If slagging tap, the separate unit rig uses 3.5m
3Small-sized air compressor gets final product, if many augers use simultaneously, the air compressor machine of available generous amount drives many constructions simultaneously simultaneously.
(5) connect according to the degree of depth in hole peace and transfer the steel pipe of slagging tap, transfer high pressure rubber hose simultaneously, until near the bottom, hole, steel pipe hangs with the hoist engine on the percussive drill, open the air compressor machine air valve that is connected with high pressure rubber hose, make pressure-air 3 arrive the steel pipe of bottom, hole along high pressure rubber hose, rise rapidly along the steel pipe of slagging tap afterwards, the slag inclusion mud of extracting out from boring in the steel pipe of slagging tap 5 is blown out boring, deliver to the reciprocating sieve place of mud veclamation case top, the slag of big particle diameter directly is separated to outside the case, the sediment of small particle diameter is the process precipitation in the mud veclamation case, enter into after the separation and carry out secondary preparation mud in the mud agitator tank, the qualified back of mud goes out steel pipe 11 by qualified slurry flows and directly is back to the hole and carries out slurries and replenish, and keeps the head pressure of mud.
(6) when this slag tap finish after, it is out-of-blast to close the air compressor machine air valve, promotes steel pipe 4-5 rice (can remove a joint steel pipe), utilizes pipe clamp the steel pipe card to be placed on the limit portion in hole.
(7) tup is put into the hole, begin boring once more, the construction of boring is finished in circulation successively.
The present invention is according to utilizing air compressor machine to give to slag tap the steel pipe bottom to send pressure-air; allow and form pressure reduction in the steel pipe; the floating aperture of going up of the sediment of bottom; utilize the mud veclamation case mud veclamation, utilization more again, not only accelerated speed of fulfiling hole, shortened the construction period; reclaimed mud; save cost, also protect construction environment, really accomplish to achieve many things at one stroke.
