The direct circulation hole-cleaning device has the advantages of being high in hole cleaning and slag removal speed, thorough in slag removal, large in influence depth, rapid to convert, economical, convenient and fast to use, and the like.
Description
Technical field
the utility model relates to a kind of direct circulation hole cleaning device.Belong to priming concrete pile hole technical field of construction in building.
Background technology
at the bottom of priming concrete pile hole, the control of sediment thickness is one of important indicator of punching (brill) hole pouring pile hole quality, and therefore removing priming concrete pile hole bottom sediment is one of important step of controlling the bored pile piling quality.The quality good or not of priming concrete pile hole will directly affect the bearing capacity of castinplace pile, especially on take impact that end resistance is main end bearing pile or friction end bearing pile more very.
hole cleaning device commonly used descends for priming concrete pile hole or the clear hole of the super dark priming concrete pile hole effect of cleaning larger aperture; Particularly, take under the condition that gravel layer is bearing stratum, more be difficult to the cobble that particle diameter is larger or rubble and remove clean.Also there is at present the pump of employing to inhale anti-circulating device and carry out hole clearly, it is heavier that but pump is inhaled in anti-circulating device gravel pump, the facility sealing performance requires high, equipment is moved inconvenience is installed between the stake hole, fault rate is relatively high, if link one occurs that sealing performance is poor, just may affect anti-circulation cleaning hole effect and time, clear hole operating efficiency is unstable.
Summary of the invention
the purpose of this utility model is, a kind of direct circulation hole cleaning device is provided, and can make up the deficiency of existing hole cleaning device, to guarantee the construction quality of priming concrete pile hole.
the technical solution of the utility model:
a kind of direct circulation hole cleaning device, comprise the airduct and the conduit that stand in priming concrete pile hole, and airduct is connected with the compressed air outlet of hemisphere press; Priming concrete pile hole aperture one side is provided with mud pit, is provided with slush pump in mud pit, and the mud delivery side of pump is connected with the upper end of conduit through mud tube.
in aforementioned means, between described mud pit and priming concrete pile hole aperture, through the mud ditch, be connected.
in aforementioned means, described priming concrete pile hole aperture is provided with the steel casing.
in aforementioned means, the air outlet of described airduct is positioned at the priming concrete pile hole bottom, and the air outlet of airduct is provided with nozzle.
compared with prior art, the utility model is applicable to clear up priming concrete pile hole or the super dark priming concrete pile hole of larger aperture, can clear up priming concrete pile hole more than 3 meters.To take priming concrete pile hole that gravel layer is bearing stratum while being cleared up, cobble that can particle diameter is larger or rubble are removed clean.The utility model is simple in structure, and light practicality is carrying out hole conveniently moving while shifting, not high to the sealing requirements of link, failure rate is low, and operating efficiency is stable.The utlity model has clearly that scarfing cinder speed in hole is fast, scarfing cinder thoroughly, affect that the degree of depth is dark, conversion rapidly, the advantage such as economy is convenient.
The accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in accompanying drawing: 1-priming concrete pile hole, 2-airduct, 3-conduit, 4-air compressor machine, 5-mud pit, 6-slush pump, 7-mud tube, 8-mud ditch, 9-steel casing, 10-nozzle.
The specific embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
a kind of direct circulation hole cleaning device, as shown in Figure 1, comprise the airduct 2 and the conduit 3 that stand in priming concrete pile hole 1, and airduct 2 is connected with the compressed air outlet of hemisphere press 4; Priming concrete pile hole 1 aperture one side is provided with mud pit 5, is provided with slush pump 6 in mud pit 5, and the outlet of slush pump 6 is connected with the upper end of conduit 3 through mud tube 7.Between described mud pit 5 and priming concrete pile hole 1 aperture, through mud ditch 8, be connected.Described priming concrete pile hole 1 aperture is provided with steel casing 9.The air outlet of described airduct 2 is positioned at priming concrete pile hole 1 bottom, and the air outlet of airduct 2 is provided with nozzle 10.
Embodiment
during concrete enforcement, as shown in Figure 1, first squeeze into a steel casing 9 in the aperture of priming concrete pile hole 1, in case aperture caves in.Then dig a mud pit 5 in priming concrete pile hole one side, mud pit is formed by the ordinary sinter brick masonry, and long 3 meters of pond is wide 3 meters, high 2 meters, thick 0.2 meter of pool wall, and cement mortar is smeared in the pool wall both sides, and the bed course of thick 100mm is done in bottom.Then dig a mud ditch 8 between the aperture of mud pit and priming concrete pile hole, the mud ditch is formed by the ordinary sinter brick masonry, and 0.5 meter of furrow width is high 0.3 meter, 0.2 meter of ditch wall thickness, and cement mortar is smeared in the pool wall both sides, and the bed course of thick 50mm is done in bottom.The junction of steel casing and mud ditch opens a gap, so that mud can flow into mud pit by the mud ditch.Then a 22KW slush pump 6 is installed in mud pit, and the steel pipe that to place respectively steel pipe that a diameter is 150mm in priming concrete pile hole be 300mm as airduct 2 and diameter is as conduit 3.BOD is installed a nozzle 10, and the airduct top is connected with the compressed air outlet of air compressor machine 4.Air compressor machine adopts 10KW apoplexy air compressor machine.The top of conduit is connected with the mud delivery side of pump through mud tube 7.
the course of work of the present utility model and principle
during clear hole, as shown in Figure 1, at the bottom of by slush pump 6, the mud in mud pit 5 constantly being injected to the hole of priming concrete pile hole 1, then start air compressor machine 4, pressure-air sprays and mixes with mud at a high speed from the nozzle 10 of airduct 2 bottoms, the impact force of pressure-air rises the sediment of the priming concrete pile hole bottom liquid level of getting up along with mud that suspends in mud in priming concrete pile hole, from the aperture of priming concrete pile hole, overflow, flow into mud pit by the mud ditch, rock grain in mud pit in sediment, mud after the precipitated filtration of sand grains injects in priming concrete pile hole again, iterative cycles until at the bottom of hole sediment thickness reach code requirement.
