Abstract
The invention relates to a method for constructing the concrete screw post of screw drilling rod central pump, and a relative screw producer, wherein it can solve the problems as high cost and hard synchronization; it comprises: first using the long screw driller to drill the hole to preset length; then the hydraulic jack extends out the screw producer to rotate reversely and lift the drilling rod, while filling over-flow concrete into the hollowing drilling rod; then drawing out the drilling rod to insert into the steel bar cage.
Description
Technical field:
The present invention relates to a kind of job practices and facility of pile foundation for building.
Background technology:
The job practices of cast-in-place concrete pile is a lot of in building operations at present, for example: Superfluid state concrete perfusion piling method, its perfusion pile can't form screw thread, there is the waste concrete, the shortcoming that cost is higher, and present existing helical burr ram construction equipment cost height, stationary problem are difficult to solve, be difficult for forming screw thread, be difficult to successfully.
Summary of the invention:
The object of the invention is to provide a kind of bearing capacity that can improve stake, reduces the auger stem center infusion superfluidity concrete helical burr ram job practices and the thread making device thereof of construction cost.
Above-mentioned purpose realizes by following technical scheme:
Auger stem center infusion superfluidity concrete helical burr ram job practices, at first hole to projected depth with the long-spiral drilling machine that is threaded producing device, start hydraulic jack then and stretch out the thread making device, counter-rotating simultaneously promotes drilling rod, when proposing drilling rod, pour into the superfluidity concrete, propose at last to insert reinforcing cage behind the drilling rod by hollow drill.
Above-mentioned auger stem center infusion superfluidity concrete helical burr ram job practices, described superfluidity concrete is the concrete of the slump at 18cm-24cm.
Above-mentioned auger stem center infusion superfluidity concrete helical burr ram job practices, any time of described startup hydraulic jack in promoting the drilling rod process opens, and the screw thread of formation is whole screw threads or part screw thread.
Above-mentioned auger stem center infusion superfluidity concrete helical burr ram job practices, the long-spiral drilling machine boring of described thread making device is one-step pore-creating or twice pore-forming.
The thread making device that above-mentioned auger stem center infusion superfluidity concrete helical burr ram job practices is used, its composition comprises: the auger stem of common long-spiral drilling machine, hydraulic jack, the thread making device, described auger stem is a hollow drill, described hydraulic jack is positioned on the helical blade of described auger stem bottom, and described thread making device is positioned at the end of hydraulic jack.
Advantage of the present invention is:
1. the present invention is when construction superfluidity concrete pile is carried brill, stretch out the thread making device by the hydraulic jack that is fixed on the helical blade of drilling rod bottom, rotation is carried boring and is shown the formation screw thread, thereby reduction construction cost, improve the bearing capacity of stake, and the pile facility can reequip on existing long-spiral drilling machine, and pile-forming effect is good, improvement cost is low, is suitable for generally promoting.
2. the present invention forms screw thread when perfusion superfluidity concrete pile, reduces concrete amount, increases the side frictional resistance and improves bearing capacity.
3. thread making apparatus structure of the present invention is simple, and cost is low, is easy to extensive popularization.
4. the present invention can one-step pore-creating, grasps the superfluidity concrete technology and is very easy to comprehension.
