Abstract
The utility model provides a soil-absorbing hole-forming drilling bit of a diamond drill, which is characterized in that the soil-absorbing hole-forming drilling bit is provided with a drilling bit. The drilling bit is arranged at the tail end of a drilling rod which is connected with a power source and is provided with soil stirring blades which are uniformly distributed at the periphery; the soil stirring blades are distributed at the periphery of the drilling bit; and soil absorbing pipelines are arranged at the interval positions of the soil stirring blades and are connected with a soil absorbing pressure pump. In the soil-absorbing hole-forming drilling bit of the diamond drill, the semi-soil-extruding operation is adopted, i.e., the drilling bit is used for stirring up a soil layer and breaking crushed stones, soft soil is pressed onto the ground by the soil absorbing pipelines, the broken stones are driven by the soil stirring blades to be extruded onto the hole wall, and after the hole wall is extruded, the compactness of the hole wall is improved without hole collapse, so that the hole forming speed is high and the hole forming quality is good.
Description
Technical field
The utility model belongs to the constructional engineering machinery field, relates in particular to a kind of parts that carry out the stake machine of foundation drilling.
Background technology
In the prior art, the hole forming method in construction work foundation pile hole has four kinds, i.e. punching, boring, manually digging hole, rotary drilling rig at present.But these four kinds of modes respectively have shortcoming.Punching stake machine uses iron hammer to impact, soil battered down extract out after becoming soil paste, but can only smashing rock to rubble, this method can't break into slurry, also coarse sand can't be broken into slurry, like this, rubble, cobble and coarse sand just are difficult to be drawn out of, thereby form the quality in sediment and influence stake hole in the stake hole.When the drill bit of bored pile stirs soil, if run into stone, just stir to enter, speed is slow, and stake hole quality is difficult to guarantee.Manually digging hole is big in the water yield, can't operation under super dark, the super dark rough sledding of drift sand of stream soil, dangerous, a hole quality is unreliable.Rotary drilling rig adopts the grab bucket operation, every bucket up and down twice, and underground water and produce water under high pressure below the compressing in the decline process, the high pressure water impact hole wall produces the hole of collapsing, and rotary drilling rig needs a pipeful of digging, and speed is slow, and quality is unreliable.
Summary of the invention
The utility model provides a kind of golden steel to bore suction soil one-tenth drill, and its purpose solves the shortcoming that prior art exists, and the machine critical piece that a kind of speed of fulfiling hole is fast, hole quality is good is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of golden steel bores inhales soil one-tenth drill, it is characterized in that: have drill bit, drill bit is arranged at the drilling rod end, drilling rod is connected with power source, drilling rod is provided with the native blade of stirring of circumference uniform distribution, stir the periphery that native blade is distributed in drill bit, the interval location that stirs native blade is provided with inhales native pipeline, inhales native pipeline and is connected with suction soil pressure pump.
The usefulness of technique scheme is: golden steel of the present utility model bores suction soil and becomes drill to adopt half soil compaction mode operation, also be that drill bit stirs mashed soil layer and broken stone, weak soil is inhaled native pipeline and is pressed ground, rubble is stirred native blade and drives to be expressed on the hole wall and compress, and hole wall is extruded the back compactness and improves and the hole of can not collapsing, thereby finger stone squeezes toward hole wall, drill bit down bores always, earth is inhaled native pipeline from high pressure, and speed of fulfiling hole is fast, and hole quality is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is the elevational schematic view of Fig. 1.
The specific embodiment
The utility model as shown in Figure 1 is that a kind of golden steel bores suction soil one-tenth drill, with maintenance adpting flange 10 two parts connection is provided with rotation motor 31 in the diving protective cover 1 of formation, rotation motor 31 connects and driving drilling rod 3, drilling rod 3 stretches out diving protective cover 1, the end of drilling rod 3 is provided with drill bit 4, the native blade 5 that stirs that has the eccentric big flabellum shape of four bending tablets at the periphery of drill bit 4, as shown in Figure 2, each stirs and the many places detiform spark of little diamond all has been installed on the native blade 5 is stirred soil point 51, be arranged on the drill bit 4 with stirring native blade 5 circumference uniform distributions, the interval location that stirs native blade 5 is provided with inhales native pipeline 6, and the golden steel in inhaling native pipeline 6 and being installed in diving protective cover 1 bores high-pressure hydraulic power suction soil pressure pump 2 and is connected; The high-pressure oil pipe that bores high-pressure hydraulic power suction soil pressure pump 2 power resources as golden steel is connected with ground active force pump by oil circuit line outlet 21, inhales and elevates above the soil after native pipeline 6 passes diving protective cover 1.
During real-world operation, golden steel is bored suction soil become drill to be located at the below of drilling bar, in deeply holing, the probing bar is fixed, and the drill bit rotation is bored sandstone broken, inhales native pipeline weak soil is extruded ground, quilts such as rubble stir native blade and drive and be expressed on the hole wall and compress, so always pore-forming.
