Description
Technical field
This utility model belongs to Bridge Pile Foundation Construction field, relates to the hole equipment after a kind of pile foundation pore-forming, is specifically related to
A kind of it is applied to super large, the mud purifying device of ultra-deep pile foundation hole cleaning.
Background technology
Super large, extra-deep hole drilling bored concrete pile are high with its bearing capacity, technical maturity, to advantages such as surrounding environment influence are little,
Large Span Bridges is used widely.During drilling construction, the thickness of sediment at the bottom of hole directly influences pile foundation bearing capacity, friction
The size of power, and then the stress performance of stake.Pile foundation hole cleaning technique is to determine the principal element of sediment effect at the bottom of cleaning hole, thus also
It it is one of the key link that controls of pile foundation quality.To using the super large of gas lift reverse circulation rig construction, extra-deep hole drilling bored concrete pile, its
Hole mode is usually, and once clear hole is coordinated with desanding case from air lift counter circulation drill mechanomotive force head grout outlet, filters out in mud
Dregs and bulky grain sand grains after, mud is by return pipe return aperture；Secondary pile hole cleaning is to be removed by rig, uses conduit to extract out
In hole, mud coordinates the clear hole of desanding case.Current this clear hole technique can make sand content in mud control at 1%-2%, but is difficult to into one
Step reduces；In mud cyclic process, desanding bottom can deposit thicker sand setting, needs artificial constantly cleaning, expend a large amount of artificial；
Clean up time is long, and once clear hole is it is generally required to 7～8 hours, inefficient.
Summary of the invention
The purpose of this utility model is to improve the structure of current emptying apparatus, to reduce sand content in mud further,
Reduce clean up time, and save empty spent by operation artificial, improve work efficiency.
The technical solution of the utility model is as follows:
A kind of mud cleaner for super large ultra-deep pile foundation hole cleaning, including a desanding case, desanding box top is provided with filtration
Sieve, sieves side is provided with scraper, and desanding case sidewall is provided with the first overfall mouth, it is characterised in that: also include a slush pump and
One cyclone separator, the pulp absorbing hole of described slush pump is internal with described desanding case to be connected, and the grout outlet of slush pump connects described rotation
The stock inlet of stream separator, the top of described cyclone separator is provided with the second overfall mouth, and the bottom of cyclone separator is provided with sediment outflow
Valve.
This utility model the most at least has the advantage that
(1), clear hole speed is fast.Existing slurry purifying equipment once clear hole it is generally required to 7～8 hours, uses this practicality
The novel once clear hole time is only 2 hours.
(2), clear hole is effective.Behind existing slurry purifying equipment once clear hole, sand content in mud can only be reduced to 1%-
2%, and behind this utility model once clear hole, sand content in mud can be reduced to less than 0.5%.
(3), can save manually.Existing slurry purifying equipment is during once clear hole, owing to mud circulation rate is slow,
Desanding bottom can deposit thicker sand setting, needs artificial constantly cleaning, expends a large amount of artificial, and this utility model installs slush pump
After, mud speed rate can greatly speed up, and desanding bottom, substantially without there is sand setting, decreases artificial.
(4) high financial profit.This utility model adds slush pump and cyclonic separation on existing mud purifying device
Device, more slightly higher than existing equipment cost, but owing to man-hour can be greatly decreased, save artificial, whole economic efficiency is far above existing side
Formula.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model includes that a desanding case 1, desanding case 1 top are provided with sieves 2, sieves 2 side
Being provided with scraper 3, desanding case 1 sidewall is provided with the first overfall mouth 4；Also include slush pump 5 and a cyclone separator 6, a described mud
The pulp absorbing hole of stock pump 5 and described desanding case 1 are internal connect, the grout outlet of slush pump 5 connect described cyclone separator 6 enter to starch
Mouthful, the top of described cyclone separator 6 is provided with the second overfall mouth 7, and the bottom of cyclone separator 6 is provided with sediment outflow valve 8.
This utility model is to add slush pump and cyclone separator on existing slurry purifying equipment.Cyclone separator
Also known as hydrocyclone, it is a kind of general equipment separating solid particle from float.Cyclone separator is according to centrifugal heavy
Fall and the principle of density contrast, when mud under pressure from cyclone separator stock inlet tangentially to enter time, can produce strong
Strong rotary motion, owing to mud is different from sand density, under centrifugal force, centripetal buoyancy, fluid drag effect, makes low density
Mud rises, and discharges from the second overfall mouth at cyclone separator top, and the big sand fallout of density is to bottom, from desanding valve row
Go out, thus reach the purpose of effective desanding.
When this utility model is embodied as, sieves can use the screen cloth of 0.5cm*0.5cm, and slush pump is equipped with 15KW electricity
Machine.One support 9, slush pump 5 and cyclone separator 6 are set in desanding case 1 side rack-mount, the bottom of cyclone separator
Overhead certain altitude, it is simple to sand flash valve door row sand.
When this utility model uses, by the second overfall mouth on the first overfall mouth on desanding case and cyclone separator respectively
Being connected with a return pipe one end, the return pipe other end leads in boring.Work process of the present utility model is as follows:
Once clear hole: the residue outlet of gas lift reverse circulation rig is connected scraper, in hole boring mud under gas pressure by going out
Slag pipe enters scraper, then flows through the sieves screen cloth of 0.5cm*0.5cm, more than 0.5cm*0.5cm clod and cobble (solid phase
Granule) it is filtered out, and mud flows directly into desanding case.Flowing into the mud in desanding case, a part is flowed back to by the first overfall mouth
In boring, another part is then sucked cyclone separator by slush pump；Mud enters in cyclone separator with tangential direction, centrifugal
High speed rotating under power effect, fine sand is deposited on bottom and goes out through sand flash valve door row, and the relatively low mud of sand factor is then from cyclone separator
The second overfall mouth at top flow back in boring.
Secondary pile hole cleaning: after once clear hole completes, gas lift reverse circulation rig is removed, transfers pile foundation steel bar cage, under steel reinforcement cage
After discharging into, installing mud in conduit extraction aperture in stake holes, conduit outlet connects scraper, carries out secondary pile hole cleaning, and secondary is clear
Hole mud cyclic process with once empty identical.
