Abstract
Sediments at the bottom of a pile hole are cleaned after pore-forming of a cast-in-situ bored pile at present; a commonly-used technology is single guide tube direct cycle cleaning or single guide tube reverse cycle cleaning; when a rock-embedded pile with extremely high quality requirements is required, the quality of the pile is difficult to achieving the standard of level A pile. In order to solve the problem that sediments for single guide tube cleaning cannot meet the quality requirements, the invention provides a hole cleaning device with double guide tubes. The hole is cleaned by adopting the double guide tubes, a water outlet of a water inlet guide tube horizontally rushes at the wall of the hole, so that the sediments adhered to the wall of the hole are cleaned through washing, the sediments after washing are sucked by a water outlet guide tube, and the sediments are discharged in time.
Description
Technical field
The present invention relates to after a kind of drilling pouring pile hole the sediment scavenge unit of bottom, stake hole.
Technical background
At present after drilling pouring pile hole, the sediment of stake hole bottom is removed, and conventional technique is single conduit direct circulation or the anti-loop cleaning of single conduit, but the sediment that is bonded at hole wall surrounding cannot be removed totally, in the time running into the very high socketed pile of quality requirement, the quality of stake is difficult to reach a class pile beacon standard.
Summary of the invention
The problem that can not meet quality requirement for solving single conduit removing sediment, the invention provides a kind of DLC hole cleaning device.
The technical solution adopted for the present invention to solve the technical problems is: adopt the clear hole of DLC, the delivery port level of penstock rushes at hole wall, and the sediment that makes to be bonded on hole wall washes away totally, and the sediment that washes away out, by water output duct sucking-off, discharges sediment in time.
The invention has the beneficial effects as follows, the sediment of bottom, stake hole can be removed totally, meets pile foundation quality requirement.
Brief description of the drawings
Fig. 1 is DLC hole cleaning device sectional drawing
Fig. 2 is DLC hole cleaning device plan view
In figure: 1. drilling pouring pile hole; 2. water output duct; 3. penstock; 4. air inlet pipe; 5. water output duct water inlet; 6. water output duct delivery port; 7. penstock water inlet; 8. penstock delivery port; 9. air inlet port; 10. gas outlet.
Specific implementation method
In Fig. 1, in drilling pouring pile hole (1), put into water output duct (2), in water output duct (2), put into air inlet pipe (4), air inlet port (9) is connected with air compressor, sediment is sucked in water output duct (2) by water output duct water inlet (5) by gas lift reverse circulation method, discharge from water output duct delivery port (6), put into again penstock (3), penstock water inlet (7) is connected with high-pressure hydraulic pump, by penstock delivery port (8), water is rushed to hole wall.
Claims (1)
1. a DLC hole cleaning device, is in drilling pouring pile hole, to put into two conduits, it is characterized in that: water is rushed at a sediment for bottom, hole hole wall by a conduit direct circulation, and the anti-circulation of another root conduit is by the sediment sucking-off of bottom, stake hole.
