Description

Split type quick hole cleaning device

Technical field

The utility model is related to building engineering equipment field, more particularly to a kind of split type quick hole cleaning device.

Background technology

At present, filled in the basis overwhelming majority of the buildings such as the bridge, house, harbour of road and rail using armored concrete Stake pile foundation is noted, deposited reinforced concrete pile is typically first drilled by boring (punching) hole machinery, then irrigates pile, Construction of Pile Bedding Boring mistake Cheng Bixu carries out mud circulation, it is therefore an objective to bottom hole boring mud (is contained in mud and suspended by mud circulation when mud off and drilling Particle) take mud-settling pit precipitation to.Then steel reinforcement cage, conduit must be installed by working procedure first borehole cleaning (removing slag) after pore-forming, Concrete perfusion after secondary pile hole cleaning is carried out again, and pile foundation is bored (punching) hole construction requirement mud and is maintained in the state of certain altitude water level Carry out, to ensure that mud has enough pressure to prevent collapse hole to hole wall, while mud must also keep circulating state with up to To the purpose of deslagging and mud slurry uniform；When boring (punching) hole, containing substantial amounts of suspended particulate (including sand or mudstone block) in mud, into Rig is stopped behind hole, and suspended particulate will be deposited in bottom hole formation sediment, if suspended particulate and sediment can not be removed totally, will Pile foundation quality is constituted a serious threat (if reinforced concrete pile bottom is more than the sediment of specific thickness, in deadweight and the work of bearing capacity Pile foundation can be caused to sink under, it is also possible to because sediment is rolled in Reinforced Concrete Core and caused by broken pile give up stake), so, Installation steel reinforcement cage, conduit are carried out again after must carrying out borehole cleaning, borehole cleaning after building code requirement, pile foundation pore-forming, then in secondary pile hole cleaning After could concrete perfusion.Borehole cleaning technique is：By borehole cleaning must be carried out after design aperture and hole depth requirement pore-forming, i.e., in hole Suspended particulate takes to outside hole to reach the purpose of borehole cleaning by mud cycle operation, prevents suspended particulate to be deposited in bottom hole and form heavy Slag, for end-bearing pile, when stake bottom remains sediment more than 5 centimetres, it is possible to cause pile foundation sinking, broken pile, influence pile foundation Construction quality, can cause whole building defect and turn into dangerous building when serious.

At present, pile foundation can effectively ensure the special borehole cleaning equipment of pile foundation quality to carry out borehole cleaning, one also without simple and feasible As the borehole cleaning technique overwhelming majority use direct circulation borehole cleanings, i.e., slush pump in mud-settling pit by sebific duct to bottom hole water filling or Former mud slowly overflows stake holes and flows to mud-settling pit in mud after being precipitated through sediment, hole, forms direct circulation, suspended particulate with Mud overflows into mud-settling pit, and suspended particulate starts precipitation, theoretically seen, in addition to wasting the substantial amounts of time, it appears that will not The problem of having much, but there are problems that in practical operation three, one, be inefficiency, the borehole cleaning time is long, generally requires 12- 72 hours even longer, but easily cause because the operating time is long thought paralysis in practical operation and perform a task perfunctorily and rare patience Go to carry out in real earnest, supervision is also relatively difficult；Larger suspended particulate (difficulty for being more than 5mm is bigger) and sediment can not be complete Thoroughly all taken out of from bottom hole, fine particle rapid precipitation can not but be pumped to bottom hole repeatedly in mud pit again.2nd, it is Because direct circulation borehole cleaning needs injected clear water, make former mud dilution circulation, be typically diluted to 3 times of former mud, the mud after dilution Enormous amount is starched, it is necessary to transport outward and handle again, to follow the line of least resistance, mud is often directly discharged into rivers during some engineering constructions, River course riverbed sludge accumulation and pollution of waterhead will be caused, future trouble is left, the volume of most of stake holes is general at 20-80 cubic metres, By the calculating of 50 cubic metres of absolute averages, as long as a building site there are 100 piles, will then there is 15000 cubic metres of mud after 3 times of dilution Slurry need it is outer transport to certain appointed place and especially handled, otherwise will cause serious environmental pollution, and numerous engineering pile radixes Amount is more than 100, and what is had reaches thousands of；In fact there are more than hundreds of even thousands of seats in each large and medium-sized city every year Newly-built building and bridge, its pile foundation enormous amount, its mud quantity produced is even more huge surprising；3rd, it is due in sedimentation basin Sediment need it is regular draw slag, the slag water content drawn out is big, in sposh state, transports outward substantial amounts and easily causes Water clock.

Reacting cycle borehole cleaning then on the contrary, it by conduit from bottom hole slurry-sucking, stake holes mouthful, hole bottom slurry ratio are back to after removing slag Great, the mud balance after removing slag is smaller, and mud will not be mixed in cyclic process therefore circulation primary is just substantially clean.Therefore by Borehole cleaning slush pump can fundamentally solve what traditional normal circulation technology was present to carry out the separation that carries out removing slag again of reacting cycle slurry-sucking Problem.

The current capital construction scale of China and building level have been walked in the prostatitis in the world, and high ferro is moved towards on a grand scale The world, but the Means of Ensuring and technology of pile foundation quality are still in relatively low level, it is impossible to do not say it is individual sorry.Social active demand It is a kind of fundamentally to ensure the equipment and technology of pile foundation quality.

Utility model content

The purpose of this utility model is to overcome disadvantage mentioned above, and there is provided the split type quick hole cleaning device of one kind, device profit It will again be sent back to after the mud pumping in stake holes to spiral-flow filter and concentrator bowl filtering with slush pump and reacting cycle work carried out in stake holes Industry, not only substantially increases borehole cleaning speed, effectively removes the solid particle in pile foundation slurry, and can realize that machinery is small-sized Change, judicial convenience reduces cost, is conducive to promoteing the wider application.

What the utility model was realized in：A kind of split type quick hole cleaning device, it is characterised in that：Including being arranged at stake Slush pump in hole and the filter for being arranged at stake holes side, the filter include frame, are arranged at frame upper end Spiral-flow filter, be arranged in frame and the collecting chamber below the spiral-flow filter, the concentrator bowl that is arranged in collecting chamber And the centrifugal driving device for being used to drive concentrator bowl to rotate in frame is arranged at, the spiral-flow filter is provided with charging Mouth, overfall and slag-drip opening, the slag-drip opening are located in concentrator bowl, and the slush pump is provided with pump inlet and pump discharge, described Pump discharge is connected by hydraulic fill pipeline with the charging aperture of spiral-flow filter, and the collecting chamber is provided with grout outlet, the eddy flow The overfall of filter and the grout outlet of collecting chamber are respectively by hydraulic fill pipeline by the slurry transportation after filtering to stake holes.
