Abstract
The hole drilling and expanding mechanism contains drilling rod and auger comprising center auger fixed on the drilling rod and fan-like bits hinged to the drilling rod. The fan-like drilling bits are hinged through a linkage to a elevating rod inside the drilling rod. There is a size determining ring around the drilling rod and a mud stopper between the drilling rod and the elevating rod. The fan-like bits are controlled by the elevating rod to expand so as to obtain various pile foundation hole of different shape. The present invention makes it possible to construct piles with great bearing capacity and less material consumption and to construct pressure bearing pile and drawing resisting pile even in low-bearing soil.
Description
The present invention relates to the invention of a kind of highrise building and the used expandable nole drilling mechanism for deposited reinforced concrete pile of large-scale structure.
The datum hole of current highrise building and the used castinplace pile of large-scale structure base generally all adopts rig boring, punching, hand excavation to add the steel concrete retaining wall and squeezes into modes such as immersed tube pore-forming and realize, this wherein the advantage compared with alternate manner of rig bore mode be to be adapted to any soil layer, and the pile foundation hole can be anchored into basement rock, thereby the bearing capacity height, can not produce harmful effect again in the construction to building on every side; But traditional pile foundation hole is because the restriction of rig drill bit structure, can only be upper and lower,, will enlarge the diameter of rig drill bit as obtaining big soil layer bearing capacity face with pile foundation hole, footpath, perhaps increase the degree of depth of rig boring, so also just increased engineering cost, cost and construction period.
The purpose of this invention is to provide a kind of expandable nole drilling mechanism for deposited reinforced concrete pile that can reduce engineering cost, construction period.
Expandable nole drilling mechanism for deposited reinforced concrete pile of the present invention, include drilling rod and drill bit, it is characterized in that drill bit is fixed in center bit on the drilling rod and hinge by the middle part and is linked to the fan-shaped drill blade that can revolve expansion on the drilling rod and forms, be provided with a shadoof in the drilling rod, the outer top of drilling rod is provided with lug, and the bottom tube wall has groove; The groove that shadoof passes on the drilling rod is connected with fan-shaped drill blade middle part hinge through connecting rod, and the upper end of fan-shaped drill blade is connected with lug hinge on the drilling rod again, also is provided with a sizing ring on the drilling rod, also is provided with a bod between drilling rod and shadoof.
The above-mentioned fan-shaped drill blade of the present invention can be made the form that penetrates.
But the present invention's reducing borehole drill construction, owing to be provided with fan-shaped drill blade, fan-shaped drill blade can be opened gradually by shadoof control when rod boring, counterboring towards periphery, thereby can obtain the stake termination of multiple ideal form, as the load stake of the big end, the stake of a plurality of load enlarged footing, be used for the up big and down small back taper stake of supporting etc.And its bore process is identical with traditional handicraft; Compare with traditional deposited reinforced concrete pile, same material can obtain bigger bearing capacity, or can reduce material consumption on the basis of same bearing capacity, and the soil layer of low bearing capacity is fully used.Compare with manually digging hole filling pile, both highly effective and safe saved the steel concrete retaining wall, can increase pile body frictional resistance bearing capacity partly again.Because pile crown can increase the range of application of stake, both can make pressure bearing pile, can do the uplift pile of slant-pull structure again.
Embodiment of the invention structure is as shown in drawings:
Fig. 1 is a structural representation of the present invention.
In accompanying drawing 1, comprise drilling rod 1 in the expandable nole drilling mechanism for deposited reinforced concrete pile of the present invention, the top of drilling rod 1 is provided with center bit 8, and center bit 8 forms can be various; Be provided with a shadoof 2 in the drilling rod 1, drilling rod 1 top is shaped on lug 7, and the bottom is shaped on groove; Pass through groove, shadoof 2 is connected with an end hinge of connecting rod 6, the other end through connecting rod 6 is connected with fan-shaped drill blade 4 hinges again, the other end of fan-shaped drill blade 4 is connected with drilling rod 2 top lugs 7 hinges, in order to reduce the resistance of boring, fan-shaped drill blade 4 can be made the break-through form, also is provided with a sizing ring 3 on the drilling rod 2, also is provided with a bod 5 between drilling rod 2 and the shadoof 1; In order to increase application life, center bit 8 and fan-shaped drill blade 4 are welded with the alloy sword.
When using steel concrete diameter variable rig of the present invention to hole, as long as in the place that needs hole enlargement, by pressing down shadoof 1, via connecting rod 6, impel fan-shaped drill blade 4 to open that soil layer bores system around the scraping, hole as need taking-up drill bit, drilling rod 1, then need only pull-up shadoof 2, pack up fan-shaped drill blade 4, just can achieve the goal.
