Abstract
The invention discloses a drilled pile drilling deviation rectification guiding device, which comprises a pipe body, wherein one end of the pipe body is provided with a drill rod connecting end, and the other end of the pipe body is provided with a drill bit connecting end; a barrel is wrapped at the periphery of the pipe body and is mutually fixed with the pipe body; and one end of the barrel towards the drill bit connecting end is distributed in a conical surface manner. The invention also provides a pile machine drill rod provided with the deviation rectification guiding device. A drill rod body is fixedly connected with the drill rod connecting end of the deviation rectification guiding device; and a drill bit is fixedly connected with the drill bit connecting end of the deviation rectification guiding device. The drilled pile drilling deviation rectification guiding device provided by the invention can be fixedly connected between the drill rod body and the drill bit through the drill rod connecting end and the drill bit connecting end, so that an interlaid soil body has a constraint effect on the barrel when the drill bit of a pile machine is used for drilling the ground and is contacted with a boulder, and the whole drill rod is continuously operated on the boulder under the guiding action of the barrel until an area in which the boulder is positioned is penetrated; therefore, the drill bit of the pile machine drill rod provided with the guiding device cannot be deviated from a set rail, and a pile hole obtained by the drilling of the drill bit is perfectly straight and has an appropriate diameter, so that the efficiency of drilling operation can be improved, the using amount of concrete can be reduced, and manufacturing cost can be reduced.
Description
Technical field
The present invention relates to a kind of drilled pile boring correcting error guidance device.The invention still further relates to a kind of stake machine drill bar that drilled pile boring correcting error guidance device is installed.
Background technology
As Fig. 1, Fig. 2, shown in Figure 3, the conventional borehole stake is in the process of drilling construction, when running into the geology of gentle breeze granite interlayer in containing in the soil layer, boulder, if adopt conventional method, drill bit tends to first off-axis and returns former axis scope then after passing through boulder, make pore-forming rear tube or reinforcing cage fail to lay down, the hole of scrapping shown in Figure 3 appears, at this moment if adopt conventional method to handle to be exactly the drill bit cleaning bottom of hole (as being that the drill bit of ￠ 600 changes the drill bit that diameter is ￠ 700 or ￠ 800 into original diameter) again that changes larger diameter, to satisfy construction requirement.Like this, fullness coefficient will increase, and be far longer than regime values, cause the concrete consumption to increase, and increase the cost of stake.
Summary of the invention
Technical problem to be solved by this invention provides a kind of drilled pile boring correcting error guidance device that can guide drill bit to creep into along pre-determined route when running into obstruction.Technical problem to be solved by this invention also comprises provides a kind of stake machine drill bar that drilled pile boring correcting error guidance device is installed, and this machine drill bar can continue to creep into along pre-determined route when running into obstruction.
For this reason, drilled pile boring correcting error guidance device provided by the invention, comprise body, body one end is provided with the drilling rod link, the other end is provided with the drill bit link, and the periphery of body is enclosed with cylindrical shell, and cylindrical shell and body interfix, the diameter of cylindrical shell is consistent with the bit diameter that is disposed, and cylindrical shell is the taper seat distribution towards an end of drill bit link.
For this reason, the present invention also provides the stake machine drill bar that above-mentioned drilled pile boring correcting error guidance device is installed, comprise the body of rod, drill bit, stake machine drill bar also comprises the correcting error guidance device, the body of rod is fixedlyed connected with the drilling rod link of correcting error guidance device, drill bit is fixedlyed connected with the drill bit link of correcting error guidance device, and the cylindrical shell in the body of rod, drill bit and the correcting error guidance device is communicated with each other by unified inner passage.
Because drilled pile boring correcting error guidance device provided by the invention can be fixedly connected between the drilling rod body of rod and the drill bit by drilling rod link and drill bit link, when the bit drills of stake machine ground and when running into boulder, the interlayer soil body plays effect of contraction to cylindrical shell, whole drilling rod continues operation on boulder under the guide effect of cylindrical shell, up to the zone of passing the boulder place, therefore the stake machine drill head that disposes this guiding device can not depart from definitive orbit, it is straight and diameter is suitable that it creeps into the stake hole that obtains, therefore can improve the efficient of bore operation, can also save the consumption of concrete, and then reduce the cost cost.
