There is following shortcoming in the above-mentioned drilling rig technique of constructing the underground foundation stake:
1, spiral drilling machine:
1) when boring in order to obtain bigger cutting force, generally adopt low rotation speed large torque to drive drill bit drilling stratum; And, generally need the spiral leaf of auger stem that high rotational speed is arranged for smooth and easy and high efficiency casting; But because the drill bit and the spiral leaf of the auger stem of this spiral drilling machine are coaxial integrative-structure, drilling and casting can't be selected two kinds of rotating speeds simultaneously, can't realize high efficiency drilling and casting simultaneously.
2), when boring is dark, can produce a phenomenon of hole deflection because auger stem rigidity is limited; And not being suitable for ovum, layer of gravel and batholith stratum creeps into.
3) when holing, occur the hole wall collapse phenomenon easily, in this case, generally need will fill mud off in the hole, and need carry out strict management, otherwise can cause environment pollution mud balance, perfusion, discharging at sandstone or than scall.
4) adopt above-mentioned mud off method, will cause the complicated of work progress: need mud to be displaced a hole, and occur the damaged quality problems of pile body section easily from mud bottom concrete perfusion.
5) the disclosed spiral drilling machine of Japanese Utility Model patent (real fair 7-3269), though can drive the drill bit low speed rotation respectively and the spiral leaf rotates at a high speed, but the relative scale of its drill bit and spiral leaf rotating speed is fixed, still there is the shortcoming that by concrete execution conditions drill bit and spiral leaf all to be adjusted to optimum speed respectively, exist and occur hole wall collapse easily, need, cause environmental pollution problems with mud off, and because the damaged quality problems of pile body section can appear in the complex process of concrete perfusion.
2, telescopic screw rig (SMD, SDA rig):
Owing to outside auger stem, set up outer tube, the problem of hole wall collapse in the time of can solving boring, but still the drilling that has an auger stem and casting can't be selected the shortcoming of different optimum speeds simultaneously.
Particularly the SDA rig exists complete machine weight big, cost height, the shortcoming of poor stability by the drill power head that separates driving that outside unit head and inboard unit head constitute.
There is following shortcoming in aforementioned drilling rig technique to the soft foundation consolidation process:
1, unidirectional rotation deep agitation driller (CDM worker's method machine):
1) when the drilling stratum in order to obtain bigger cutting force, wish that low rotation speed large torque drives drill bit drilling stratum, and for the cement paste that injects with fully mixed by the loose native sand of drilling is high efficiency, wish that paddle can rotate at a relatively high speed, but because the drill bit and the paddle of puddler are coaxial integrative-structure, drilling and stirring can't be selected two kinds of rotating speeds simultaneously, can't realize high efficiency drilling and stirring simultaneously, and rate of penetration is lower.
2) because the unidirectional rotation of puddler, when running into viscous soil horizon, clay can be bonded in gradually and form clay on the paddle and stick together, and with the paddle corotation, and can't play the effect that cement paste and native sand fully mix, and causes quality problems.
2, two-way rotation deep agitation driller (ASC worker's method machine):
Though this machine can drive the drill bit low speed rotation respectively, puddler rotates at a high speed, because two groups of paddles on the puddler remain to same direction rotation, still exists cohesive soil and paddle to be bonded to and sticks together, and produces the problem of corotation.
Above-mentionedly construct the underground foundation stake and also there is function singleness in two class rigs of soft foundation consolidation process, uses circumscribed shortcoming is arranged: though on the driving principle of unidirectional or two-way rotation, this two classes rig seems identical, but because construction purpose difference, absolute tachometer value is mutually far short of what is expected, and for example: the various rig ranges of speeds of constructing the underground foundation stake are at 3～40min
-1, and to the rig range of speeds of soft foundation consolidation process at 20～80min
-1Even and same class rig because execution conditions (as formation condition, pore size) difference, needed rotating speed is also different.Therefore,, construct the underground foundation stake or, need select different rigs respectively for use, make that investment increases, utilization rate of equipment and installations is low the soft foundation consolidation process according to prior art.
