Abstract
Provided is a sleeving spiral drilling machine for pile head processing. The sleeving spiral drilling machine for pile head processing comprises a walking-rotary system, a amplitude variation device and an extensible drill stem, wherein the upper end of the extensible drill stem is connected to the amplitude variation device, the lower end of extensible drill stem is connected with a driving rotating electric machine, the tail end of the extensible drill stem is connected with a spiral drill, and sleeving is arranged on the outer side of the spiral drill. The sleeving spiral drilling machine for pile head processing has the advantages of high work efficiency, good economical efficiency, and convenient and fast follow-up construction. Meanwhile, the sleeving spiral drilling machine for pile head processing is suitable for immediate processing construction work after cast-in place pile is filled with underwater concrete.
Description
Technical field
The utility model relates to a kind of horizontal auger for the pile crown processing.
Background technology
China's bored pile pile crown processing at present is many after the cushion cap excavation, and the method that cuts has two kinds of ways usually.The one, use the instruments such as artificial cooperation pneumatic pick, drill rod to carry out pile crown and cut.The 2nd, first cut the main muscle of bored pile, peel off, then the method for ring cutting pile crown.These two kinds of methods all exist damages the shortcomings such as large, that expense is high, work efficiency is full to pile crown concrete, main muscle.
Excavate aspect operation and namely carry out pile crown after drill-pouring pile underwater concrete perfusion is complete, domestic only have the steel of lengthening casing to pile crown, manually excavates the concrete trial of pile crown after draining mud, and its poor stability, work efficiency are not high.
The utility model content
Its purpose of the utility model just is to provide a kind of horizontal auger of processing for pile crown, has that work efficiency is high, good economy performance, follow-up construction characteristics easily.Be applicable to the complete rear pile crown of drill-pouring pile underwater concrete perfusion and immediately process construction operation.
The technical scheme that realizes above-mentioned purpose and take, comprise traveling, rotary system, luffing device and scalable drilling rod, described scalable drilling rod upper end connects luffing device, scalable drilling rod lower end connects the active rotation motor, scalable drilling rod end connects augers, is provided with sleeve pipe outside described augers.
Compared with prior art the utlity model has following advantage.
1) work efficiency is high, and the rear laitance that only needs jetting to clean out pile crown in the reinforcing cage scope of cushion cap excavation knocks out the outer residue pile crown concrete of reinforcing cage with iron hammer or pneumatic pick and namely completed pile crown processing construction.
2) good economy performance, if through this technology construction of measuring and calculating wide-scale adoption, but its decrease bored pile pile crown disposal cost.
3) follow-up construction is convenient, after excavation of foundation pit is complete, just can complete the residue work for the treatment of of pile crown when hanging reinforcing bar to foundation ditch, has realized the seamless link between excavation of foundation pit and cushion cap reinforcing bar working procedure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure schematic diagram.
The specific embodiment
Comprise traveling, rotary system 1, luffing device 2 and scalable drilling rod 3, as shown in Figure 1, described scalable drilling rod 3 upper ends connect luffing device 2, scalable drilling rod 3 lower ends connect active rotation motors 4, and scalable drilling rod 3 ends connect augers 5, and described augers 5 outsides are provided with sleeve pipe 6.
Pile crown place concrete can not stop to be lifted when perfusion in China's bored pile construction process, for not affecting the concrete quality of pile crown, underwater concrete is mixed with retarding agent more, according to code requirement, when the perfusion of drill-pouring pile underwater concrete is complete, pile crown place concrete does not all have initial set, and so just having created for the concrete advanced processing of our pile crown may.The principle of this device is exactly by the drill bit cutting and crushing underwater concrete of initial set not yet, and the principle by conveying worm, outside the concrete belt after fragmentation is portalled, reaches the purpose of pile crown advanced processing.
Design feature is:
Carry out instant work characteristics and the working environment of processing of bored pile pile crown according to the horizontal auger that is used for the pile crown processing, we design this frock need possess the traveling ability, self-ability to work without Aided Machine, the strong adaptability ability of replaceable different-diameter drill bit can be grown the deep hole work capacity that degree of depth pile crown is processed.
Estimate length 10m during a whole set of tooling device transportation traveling, wide 3m, height 3m gross weight is no more than 20t.By walking, steering, luffing device, scalable drilling rod, the active rotation motor, sleeve pipe, the first-class part of auger forms.
this device carries out the instant method of processing of bored pile pile crown, after the perfusion of drill-pouring pile underwater concrete is complete, extract conduit, be used for the horizontal auger of pile crown processing by traveling, rotary system walks to side, stake position, start luffing device and uprightly play large arm drilling rod, carry out horizontal auger in place, make the center, position, centrally aligned hole of augers, putting down telescopic drill rod makes augers arrive floating quarrel face, start the rotation of active rotation motor drives augers, to float the default above concrete of absolute altitude of quarrel and pile crown pierces in augers, after the scale on telescopic drill rod shows that the bottom of augers arrives default absolute altitude, on pull out drilling rod, augers is proposed bored pile, with the floating quarrel in augers, concrete is cleaned out, complete pile crown and immediately process construction operation.
Claims (1)
1. one kind is used for the horizontal auger that pile crown is processed, comprise traveling, rotary system (1), luffing device (2) and scalable drilling rod (3), it is characterized in that, described scalable drilling rod (3) upper end connects luffing device (2), scalable drilling rod (3) lower end connects active rotation motor (4), and scalable drilling rod (3) end connects augers (5), is provided with sleeve pipe (6) outside described augers (5).
