Description
Technical field
The utility model relates to the drilling tool in the mixing pile machine.
Background technology
Along with the continuous expansion of mixing pile machine utilization scope, also more and more higher to the requirement of mixing pile machine drilling tool.The pile strength of conventional cement mixing method significantly reduces with the increase of the degree of depth, the shearing force that produces when blade stirs is big, mixing pile construction is big to the disturbance of pile peripheral earth, exist that mixing direction is single, ground emits slurry, stir inadequately evenly, the drilling rod the inside advances easily that slurry stops up, pile quality is poor, problems such as pile inefficiency.Yet there are no the report that can overcome the above problems simultaneously.
Summary of the invention
The utility model is single for solving existing mixing pile machine mixing direction, stirs inhomogeneously, and problem such as drilling rod stops up easily, and pile quality is poor, efficient is low proposes the drilling tool of the two-way stirring of a kind of mixing pile machine.
The purpose of this utility model is achieved through the following technical solutions: the drilling tool of the two-way stirring of mixing pile machine, comprise water tap, core pipe, interior drilling rod and outer drilling rod, drilling rod and outer drilling rod bottom are installed stirring vane and drill bit respectively in it, it is characterized in that below water tap, being equipped with transfer case, establish three mutual 90 ° taper gear with curved teeth transmission mechanism in the transfer case, be connected with outer drilling rod with interior drilling rod respectively with outer mandrel by inner spindle, drive the two-way rotation of stirring vane and drill bit and stir.
The utility model also has following technical characterictic:
The adpting flange of described transfer case and outer drilling rod adopts the tubular loose flange to combine with mounting flange, interior drilling rod and outside be provided with interior tool joint more than at least one place between the drilling rod.
In described drilling rod and outside be filled with liquid medium between the drilling rod.
The utility model compared with prior art has significant advantage:
One, owing to adopted 90 ° of transmissions of taper gear with curved teeth, its stable drive, simple in structure, compact.Volume is little, in light weight, the eccentric weight when having reduced transmission.The adpting flange of transfer case and outer drilling rod adopts the tubular loose flange to combine with mounting flange, in maintenance overhaul during the drilling rod adpting flange, can be along outer drilling rod slip loose flange, and make more reasonable structure, maintenance and inspection more convenient.The oil or the liquid medium of filling used oil or other type between inside and outside drilling rod, be full of whole drilling rod gap (generally highly being 18 meters), its oil column forms certain pressure balance to the pressure and the bit exterior slurries pressure of drill bit sealing place, and drilling rod and the sufficient lubrication of drill bit seal in keeping, help the sealing of drill bit, prolong the application life of drill bit.
Two, adopt this drilling tool to make the pile quality of agitation pile more even, pile strength is less along change in depth, has improved mixing uniformity effectively, has eliminated ground and emit the slurry phenomenon, increase effective reinforcement depth.When using this bidirectional stirring pile drilling tool construction, because inside and outside drilling rod direction of rotation is opposite, blade stirs the shearing force basic neutralisation that produces, can reduce the disturbance of mixing pile construction to pile peripheral earth, make the stirring technique stirring efficiency improve, the construction technology that conventional agitation pile four can be stirred two sprays changes two into and stirs a spray, and the construction energy consumption is constant substantially, and work efficiency can double.Also change drilling tool in the past and stopped up the shortcoming of pile inefficiency easily.Under engineering geological conditions and the essentially identical situation of design parameters, bidirectional stirring pile can be saved the engineering time, improve consolidation effect, and good practicability and economy are arranged.
Three, have the function of reequiping on existing stake machine, only needing to change on former stake machine this drilling tool of cover can use.Repacking is convenient, rapid, need not special requirement, saves time, saves, and cost is low, dependable performance.
