Detailed description of the invention
Being described in further detail technical solutions of the utility model with specific embodiment below in conjunction with the accompanying drawings, this utility model is only explained by described specific embodiment, not in order to limit this utility model.
Embodiment 1: as shown in Figure 1, a kind of diving drill machine for direct circulation deslagging of this utility model, including square kelly 1, lateral confinement 2 on the ground it is provided with between described square kelly 1 and pile foundation equipment, the bottom of described square kelly 1 is provided with the gear 4 driven by motor 3, the bottom of described gear 4 connects has drill bit shaft 11, the top of described drill bit shaft 11 to be provided with tapered drill bit 6, and the bottom of described drill bit shaft 11 is provided with drill bit 9；Described drill bit shaft 11 bottom to described tapered drill bit 6 bottom a length of 0.6～3.0m or 1～3 times of described tapered drill bit 6 diameter；The side of described rig is provided with a gas-liquid input port 15, and from described gas-liquid input port 15, the junction to described drill bit shaft 11 is provided with the first pipeline 14, be provided with in described drill bit shaft 11 axially through second pipe 5, described first pipeline 14 connects with second pipe 5；The lateral surface of described drill bit shaft 11 is provided with ash pit 7.
Embodiment 1 can realize solution-air (water/mud) unification technological process:
The drill bit 9 of rig is directed at the position needing boring, adjust the perpendicularity of drill bit shaft 11, gear 4 under the driving of motor 3 with 45～120 revs/min of rotational speed and drive drill bit 9, air-flow is first inputted by an air pump and by being arranged on the gas-liquid input port 15 of rig side, stream pressure 0.5～5MPa, it is as the criterion with soil/slurry slurry pressure in overcoming hole, drill bit 9 rotates and breaks ground, the air-flow of input is discharged from drill bit 9 and is carried drill bit 9 along drill bit shaft 11 and ash pit thereon 7 and bore and stir the boring mud of formation and move upward, open slush pump (generally 3PN, 4PN), flow 50～200m3null(selection of above-mentioned pressure and flow belongs to the common knowledge of the art to/h，Do not repeat them here)，When drill bit 9 buries，By this slush pump, the mud in mud pit is poured into gas-liquid input port 15，Mud inputs mud by gas-liquid input port 15 tailing edge the first pipeline 14 and the second pipe 5 drill bit 9 bottom drill bit shaft 11，If be provided with reflux valve on airflow line，The most above-mentioned input air-flow and mud pour into, and do not have sequence requirement，The mud poured into is discharged from drill bit 9 and is moved upward along drill bit shaft 11 and ash pit thereon 7 and self-drilling aperture 16 is returned out，Enter back into mud pit，Mud pit mud in suspension at the middle and upper levels is inputted from gas-liquid input port 15 by slush pump and until drill bit 9 again，In mud cyclic process, boring mud is carried and portals，Meanwhile，Flow in described first pipeline 14 and second pipe 5 mixture 10 of mud and air-flow，The gas-liquid discharged from drill bit 9 and formed upwards along drill bit shaft 11 and ash pit thereon 7 flows to 8，Boring mud is carried out aperture 16，Until completing boring，Slush pump and air pump is closed after completing boring.In tapping process, air-flow plays broken boring mud, assists the effect of mud upwards deslagging.The boring mud formed at drill bit 9 upwards drains at tapered drill bit 6 under air-flow and water/mud blow row's effect along drill bit shaft 11 and ash pit thereon 7, then is carried under circulating mud and airflow function with the boring mud under the drilling of tapered drill bit 6 and portal.This utility model rig utilizes drill bit 9 first to dig a diameter vertical aperture suitable with drill bit shaft 11 by increasing the drill bit 9 of drill bit shaft in drilling process, less because increasing the aperture of drill bit 9 cutting of drill bit shaft, it is the least with soil layer frictional resistance, creeps into perpendicularity on the ground and easily keep under the lifting of lifting means.Also have, lateral confinement 2 on the ground is there are on ground square kelly 1 and pile machine equipment, tapered drill bit 6 is subject to lateral confinement 2 on the ground by square kelly 1, tapered drill bit 6 is underground lateral confinement further through the vertical keyhole formation dug by its bottom drill bit 9 of drill bit shaft 11 lengthened, tapered drill bit 6 rotates under the synergy of upper and lower two lateral confinement and is drilled down into, thus ensure that the perpendicularity of pore-forming.Soil (stone) is constantly bored under air-flow, water/mud recycle stream effect and stirs into the boring mud that can be carried out aperture 16 by air-flow and water/mud recycle stream by tapered drill bit 6 and drill bit 9, is finally drilled to given size and the satisfactory vertical circular hole of perpendicularity.
Embodiment 2: as shown in Figure 2, embodiment 2 is on the basis of above-described embodiment 1, change specializing in gas-liquid input port 15 therein the blowing mouth 15 ' of air inlet into, simultaneously, liquid-transport pipe-line 12 it is provided with by described rig, the top of described liquid-transport pipe-line 12 is inlet 13, the top of the described tapered drill bit 6 of the top-down sensing of liquid outlet of described liquid-transport pipe-line 12.
Embodiment 2 can realize solution-air (water/mud) point for technological process, with being different only in that of above-mentioned gas and water/mud unification technological process: open air pump and input air-flow to blowing mouth 15 ', stream pressure can be 0.5～5MPa, it is as the criterion with soil/slurry slurry pressure in overcoming hole, drill bit 9 rotates after breaking ground opens slush pump (generally 3PN, 4PN), flow 50～200m3/h；During the piercing of drill bit 9, when drill bit shaft 11 is fully embedded in soil, having this slush pump to be poured into the inlet 13 at the top of liquid-transport pipe-line 12 by the mud in mud pit, mud inputs in the hole formed by tapered drill bit 6, flow at the bottom of drill bit 9 hole along drill bit shaft 11 and ash pit thereon 7；During drill bit 9 pierces, the air-flow inputted by blowing mouth 15 ' is along the first pipeline 14 and second pipe 5 until discharging from drill bit 9, and form gas-liquid mixture with the mud being delivered to drill bit 9 by the inlet 13 of liquid-transport pipe-line 12, the gas-liquid formed upwards along the ash pit 7 in drill bit shaft 11 under pressure flows to 8, carry drill bit 9 and tapered drill bit 6 bores the boring mud stirred and returns out entrance mud pit from aperture 16, mud pit mud in suspension at the middle and upper levels is inputted liquid-transport pipe-line 12 by slush pump again until at the bottom of hole, realize the circulation of mud, in mud cyclic process, boring mud is carried and portals, in the process, air-flow plays broken boring mud, assist the effect of mud upwards deslagging, slush pump and air pump is closed after completing boring.
Although embodiment 2 and embodiment 1 belong to the concrete structure of this utility model diving drill machine, but the solution-air (water/mud) achieved by embodiment 2 point is for technological process, facilitates the offer of gas/liquid, has more preferably operation and practicality.
Although this utility model being described above in conjunction with figure; but this utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematically; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the case of without departing from this utility model objective, it is also possible to make many variations, within these belong to protection of the present utility model.
