Abstract
Auger stem center infusion superfluidity concrete helical burr ram job practices and thread making device thereof, 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, has the waste concrete, the shortcoming that cost is higher, and present existing helical burr ram construction equipment cost height, stationary problem is difficult to solve, and is difficult for forming screw thread, is difficult to successfully.The present invention can overcome the above problems, 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 the thread making device that hydraulic jack stretches out its end then, counter-rotating simultaneously promotes drilling rod, hollow part by drilling rod when proposing drilling rod pours into the superfluidity concrete, proposes at last to insert reinforcing cage behind the drilling rod.The present invention is applicable in the various building operations.
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 the thread making device that hydraulic jack stretches out its end then, counter-rotating simultaneously promotes drilling rod, hollow part by drilling rod when proposing drilling rod pours into the superfluidity concrete, proposes at last to insert reinforcing cage behind the drilling rod.
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 and is formed screw thread when boring, 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.
Description of drawings:
Accompanying drawing 2 is to make the constructing structure schematic diagram that screw thread also pours into the superfluidity concrete simultaneously according to method of the present invention.
Accompanying drawing 3 is the constructing structure schematic diagrames that propose to insert behind the drilling rod reinforcing cage according to method of the present invention.
Accompanying drawing 4 is structural representations of superfluidity concrete helical burr ram thread making device.
The specific embodiment of the present invention:
Embodiment 1:
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,, propose at last to insert reinforcing cage behind the drilling rod by the hollow superfluidity concrete that pours into of drilling rod.
