Abstract
The utility model discloses a long rod type hole leading pile machine which comprises a mobile chassis, a derrick, a power mechanism, a drilling rig, and a drilling rod. The movable chassis can move laterally and back and forth. The derrick is vertically arranged on the movable chassis and is close to one end of the movable chassis. The derrick is connected with the other end of the movable chassis through a supporting rod. A guide platform is arranged at the upper end of the derrick. The power mechanism comprises a power head and a lifting mechanism. The power head is composed of a cycloid deceleration mechanism. The lifting mechanism is arranged on the movable chassis, penetrates through the guide platform through steel rope and is connected with the power head suspending in air. Pressure is applied through the self-gravity of the power head. At lifting time, the lifting mechanism drives the power head to move upward. The drilling rig is a down-the-hole type hole leading drill head. The drilling rod is connected between the power head and the drilling rig. The power head drives the drilling rod to rotate and drive the drilling rig to rotate. The long rod type hole leading pile machine effectively solves the problem that hole leading loses efficacy, can be remarkably increased in capacity of penetrating through geological hard layers, especially, deep thick gravel layers, and has the advantages of using one drilling rod to drill to the bottom, having no need of replacement of drilling rods, and being high in working efficiency.
Description
The utility model relates to a kind of constructional engineering machinery, relates in particular to a kind of long-rod type and draws hole stake machine.
Background technology
Advantages such as industry is used pile foundation in a large number with the development of civilian construction, and the PHC pile tube is suitability for industrialized production, is easy to guarantee with quality, and speed of application is fast, and cost is low and become main selection and the developing direction of stake for building, the whole world is all general a large amount of the use.In fact, in PHC tube pile construction process, as underground block of stone, the pile body drift can often occur and tilt or the pile body breakage, even broken pile can't continue piling.According to designing requirement, above-mentioned phenomenon occurring must ascertain the reason, and after carrying out necessary processing, can continue construction.But, how to overcome the PHC pile tube and penetrate closely knit thick dark sandy gravel stratum, the hard formation such as lithosphere or riprap layer, make PHC stake stake end can enter smoothly the bearing stratum of designing requirement? the domestic job practices that makes static pressure PHC pipe pile end penetrate the closely knit hard formations such as thick dark sandy gravel stratum is mainly to draw hole in hard formation at present, the method of drawing hole mainly contains two large classes: a class is water jetting: in the process of static pressure, place water pipe and tracheae in PHC pile tube inwall cavity by auxiliary equipment, wash away the hardpans such as gravelly sand of stake end by aqueous vapor, reach the effect that reduces end resistance, make static pressed pile stake end penetrate this layer, another kind of is to creep into drawing bore method: before advancing pile driving construction, on the piling position first with drilling equipment the mode from earth's surface to set depth bored emptying aperture ground, pan soil is taken out, and then telephone-moving is in place to this position again for the stake machine, puts into the PHC pile tube and again constructs.First kind water rushes drawing bore method and easily produces the pile perimeter resistance loss, reduce the bearing capacity of pile of PHC pile tube, cause a large amount of ponding in construction plant simultaneously, construction costs is high, long in time limit, and the another kind of drawing bore method that creeps into is used the driven by rotary disc drilling rod to advance the stone layer, still, the pile body drift can often occur tilts or the pile body breakage, even broken pile can't continue piling, also very easily produces collapse hole or inclined hole, cause draw hole inefficacy or pile body inclining and cause static pressed pile still can't penetrate closely knit hard formation or cause constructing invalid.How overcoming the above construction difficult problem that hole penetrates closely knit hard formation that draws, is the current domestic technical barrier faced.
In addition, present draw hole stake machine and generally will connect and draw vent stem, but draw vent stem because derrick is too low, make drilling rod too short, if reach rock stratum, must will add bar, thus waste of manpower and cost, and efficiency is not high.
