Description
Technical field
The invention belongs to pile foundation engineering field, particularly relating to a kind of equipment for excavating square stake holes.
Background technology
Compared with circular stake, barrette uniform section, etc. material situation on the downside of friction area larger, which thereby enhance the side-friction force of stake, significantly add the bearing capacity of stake, no matter as antislide pile in deep foundation ditch, high slope engineering, or as bottom bearing structure in other Foundation Designs, the mechanical property of barrette is all better than circular stake.
But the rotary drilling rig of extensive use in the market only can be used for circular stake of constructing, mainly rely on hand excavation to realize pore-forming for barrette, safety is poor, and operating efficiency is low, can not meet the related request of national security production and engineering construction.
Summary of the invention
The present invention aims to provide a kind of barrette pore-forming equipment, is applicable to the construction in soil property, rock quality layer, solves barrette safety, Quick mechanical pore-forming problem.
For this reason, the technical solution adopted in the present invention is: a kind of barrette pore-forming equipment, comprise main frame running gear, drilling rod and creep into power section, the described power section driving drilling rod that creeps into moves up and down and rotary motion, it is characterized in that: also comprise the rig back cover and rig fore shell that are sleeved on drilling rod lower end, rig back cover is positioned at the top of rig fore shell, propulsive mechanism is provided with in the cavity that rig back cover and rig fore shell surround, rig back cover is for being supported on borehole sidewall, the bottom surface of described rig fore shell is provided with cutting assembly, some tumbling-type cutting knife compositions of the rectangular array distribution of described cutting assembly, described propulsive mechanism is advanced by rig fore shell and regains cutting assembly, the lower end of described drilling rod connects center bit, described center bit is ahead of the plane at cutting assembly place, center bit is driven to be rotated down in advance and to creep into by creeping into power section, the digging excavation in hole, square-section is carried out again by cutting assembly.
Preferred as the first of such scheme, described center bit adopts to revolve and digs formula center bit, and carries and get out slag.
Another kind as such scheme is preferred, and described center bit adopts screw center bit, and drilling rod is provided with slag notch, and slag notch is higher than rig back cover and flush with the top of screw center bit.
The invention has the beneficial effects as follows: this equipment is by the leading rotary drilling of center bit, get circular stake holes, form free face release stress, driving is followed again by cutting assembly, form square stake holes, it is all applicable in soil property, rock quality layer, achieves the mechanical hole building of barrette, and safety is higher, speed of fulfiling hole fast, good economical benefit.

Fig. 2 is the partial sectional view of Fig. 1.
Fig. 3 is the upward view of cutting assembly and center bit in Fig. 1.
Fig. 4 adopts to revolve the partial schematic diagram digging formula center bit.

Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the invention will be further described:
Shown in composition graphs 1-Fig. 3, a kind of barrette pore-forming equipment, primarily of main frame running gear 1, drilling rod 2, creeps into the compositions such as power section 3, rig back cover 4, rig fore shell 5, propulsive mechanism 6, cutting assembly 7 and center bit 9.
Main frame running gear 1 is the main part of whole equipment, realizes the walking of equipment and the installation of remainder by main body running gear 1.Creeping into power section 3 drives drilling rod 2 to move up and down and rotary motion, belongs to routine techniques, does not repeat them here.
Difference is: be set with rig back cover 4 and rig fore shell 5 in the lower end of drilling rod 2, rig back cover 4 is positioned at the top of rig fore shell 5, in the cavity that rig back cover 4 and rig fore shell 5 surround, be provided with propulsive mechanism 6.
Rig back cover 2 is for being supported on borehole sidewall, and the bottom surface of rig fore shell 5 is provided with cutting assembly 7.Shown in composition graphs 2, some tumbling-type cutting knifes 8 of the rectangular array distribution of cutting assembly 7 form.Propulsive mechanism 6 is advanced by rig fore shell 5 and regains cutting assembly 7, the lower end of drilling rod 2 connects center bit 9, center bit 9 is ahead of the plane at cutting assembly 7 place, drive center bit 9 to be rotated down in advance to creep into by creeping into power section 3, then carry out the digging excavation in hole, square-section by cutting assembly 7.
Center bit 4 is divided into and revolves the formula of digging and screw two kinds.As shown in Figure 4, center bit 4 adopts and revolves and dig formula center bit, and carries and get out slag.As shown in Figure 5, center bit 4 adopts screw center bit, and drilling rod 2 is provided with slag notch 2a, and slag notch 2a is higher than rig back cover 4 and flush with the top of screw center bit.
The driving pore formation step of employing barrette pore-forming equipment is: rig back cover is supported on hole wall, ready → center bit rotates after excavation → cutting assembly digging excavation → rig fore shell advances a stroke downwards, driving stopping → rig back cover supports to be regained, downward slippage haul distance → start new P. drechsleri.
During work, first rig back cover is supported in hole wall to position, center bit is ahead of cutting assembly certain distance and creeps into downwards in advance, get out circular port, dynamical system drives cutting assembly to follow driving, form square hole, each P. drechsleri promotes rig fore shell by propulsion system and cutting assembly is walked downwards.
The spacing of center bit and cutting assembly can realize free adjustment, to meet the needs of Different Strata condition, reaches the best work efficiency of driving.
Native slag in borehole process is discharged by center bit, adopts to revolve to carry when digging formula drill bit to get out slag, and when adopting screw drill bit, dregs rotates to rise along the body of rod and directly discharges from slag notch.
Drilling rig housing (comprising before and after rig and rig back cover) plays guiding control action in creeping into, often during circulation driving, rig back cover is fixed on hole wall, ensures that drilling rig housing is not moved, rotates, rig fore shell promotes walking downwards by moving system, guarantees that straight line is constructed.
