Abstract
The utility model relates to a pile foundation construction device. The retaining hole-drilling pouring pile machine the patent applies to disclose the device comprising a pile-tool support frame and the positioning mechanism thereof. The pile tools arranged with the support of the pile-tool support frame includes a sinking pipe and the sinking power part thereof, as well as a long spiral drill and the spiral power part thereof, wherein the long spiral drill operates the internal arrangements thereof along the axial line of the sinking pipe; the pipe wall of the upper part of the sinking pipe is provided with a soil discharge pipe for discharging soil screwed out by the long spiral drill. The technology has the advantages of high pile forming quality, high bearing capacity, high efficiency and easy control.
Description
Technical field
The utility model relates to building pile foundation foundation construction stake machine technology.
Background technology
Existing pile foundation piling method mainly contains pipeline sinking pile and long auger stake, classify by the power mode, pipeline sinking pile is involving vibrations formula pipeline sinking pile and static pressure type pipeline sinking pile again, owing to have soil compaction effect in the pipe pile settling construction, be prone to technical problems such as squeezing stake, broken pile, undergauge, broken point and gulp down point and also take place often, so replace pipe pile settling construction technology at present, using is long spiral infusion concrete drill hole pile constructing process more widely.Yet also there are a lot of technical problems not as people's will in long spiral infusion concrete drill hole pile constructing process, and the surflaes that needs outward transport is in a large number stacked in first job site, and the pile foundation construction scene is very chaotic; The main weakness of long auger piling method is: carry when boring, its core tube valve be if can not in time open, and collapses in the stake bottom outlet side soil, underground water seepage flow in the stake hole, and then limb causes undergauge, stake end loosened soil, and forming does not have real stake; In addition, can concrete by drilling tool core pipe continuous uninterrupted perfusion, also can only be listened and is ridden perception to judge by constructor's ear usually, needs the constructor that enough construction experiences are arranged.Because of the existence of multiple uncertain factor, the practice of construction operation causes the pile foundation bearing capacity to reduce, and has influenced its pile quality greatly.For solving long screw pile end undergauge, loosened soil problem, the Chinese patent technology has also proposed multiple solution, as Chinese patent: the patent No. is: 99108024-6, name are called " cast-in-situ method for forming piles by drilling hole and pouring grout ", its technical scheme is at drilling tool lifting forward direction stake end perfusion retarded cement slurries, till the position that the undergauge and the hole danger of collapsing do not take place, drilling tool proposes the back fully and put reinforcing cage in the hole, and concrete perfusion reclaims the retarded cement slurries simultaneously again.Existing various stake each have their own characteristics of machine technology scheme and technique effect, but ubiquity complicated operation, construction technology are difficult to series of technical such as assurance.
Summary of the invention
The breast wall type cast-in-situ bored machine that provides a kind of pile quality height and construction technology to be easy to operate and control is provided invention order of the present utility model.The breast wall type cast-in-situ bored stake machine that the utility model provides, its major technique content is: a kind of breast wall type cast-in-situ bored machine, include a tool bracing frame and a detent mechanism thereof, the stake tool that is supported in a tool bracing frame setting comprises immersed tube and submerged dynamic assembly unit and long screw auger tool and spiral power part thereof, the long screw auger tool moves in it along the immersed tube axis and is provided with, and immersed tube top tube wall is provided with the long screw auger tool and screws out native casting pipe.
The disclosed breast wall type cast-in-situ bored machine technology scheme of the utility model, by walking the long screw auger tool that is arranged at axis in the hollow immersed tube, promptly overcome the existing soil compaction problem that has a strong impact on pile quality of existing pipe pile settling construction technology as stake position soil discharger.Immersed tube in the technical program has constituted the retaining wall parts of long screw auger tool perfusion pile operation in fact, in lifting of long screw auger tool and concrete perfusion process, the drilling tool bottom valve can not in time be opened, work because of augers is positioned at immersed tube all the time, the existence of immersed tube has avoided that stake end caves in, seepage action of ground water.Thereby effectively overcome drilled pile end loosened soil problem, and guaranteed the continuous uninterrupted concrete perfusion, so the technical characterstic that present technique has pile quality height, bearing capacity height, efficient height and is easy to control.In addition, the stake hole soil that the long screw auger tool is discharged is concentrated by immersed tube casting pipe and is discharged, and is directly loaded by load wagon and clears, thereby improved the job site environment greatly.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the breast wall type cast-in-situ bored machine of the present patent application
Fig. 2 and Fig. 3 are respectively the side direction structure chart and the main TV structure figure of Fig. 1 pile frame part.
The specific embodiment
As shown in Figure 1, the disclosed breast wall type cast-in-situ bored machine of the present patent application includes a tool bracing frame 1 and detent mechanism 2 thereof, and stake tool bracing frame 1 is vertically installed on the body 3.The stake tool that is arranged at a tool bracing frame 1 comprises immersed tube 4 and submerged dynamic assembly unit 40 and long screw auger tool 5 and spiral power part 50 thereof, immersed tube submerged dynamic assembly unit 40 wherein can adopt vibration actuating unit or static pressure actuating unit, and what provide in this accompanying drawing structure is the vibration actuating unit.Long screw auger tool 5 moves setting along immersed tube 4 axis in immersed tube, immersed tube 4 top tube walls are provided with long screw auger tool 5 and screw out native casting pipe 6, in the present embodiment, discharge by casting pipe 6 smoothly for making a hole soil, on the immersed tube tube wall interface of casting pipe 6, be provided with the casting vane 60 that drives by long screw auger tool screw thread, by its vane stake hole soil zone gone into casting pipe 6 and discharge.Immersed tube 4 and long screw auger tool 5 traction enhancement mechanisms are the hoist and traction machine structure 7 that is arranged on the body 3.
Realize the breast wall type cast-in-situ bored job practices of the technical program by above-mentioned stake machine.The key step of this breast wall type cast-in-situ bored job practices is: the stake machine is in place in design stake position, start spiral power part 50 and drive long screw auger tool 5, and startup immersed tube submerged dynamic assembly unit 40 sinks to immersed tube 4, long screw auger tool 5 pierces in the process and constantly pipeline sinking pile hole soil is promoted, and, clear by direct loading of load wagon that wait casting pipe below by 6 discharges of casting pipe.After immersed tube 4 and long screw auger tool 5 all reach the bearing stratum depth of design elevation, start high-pressure pump concrete perfusion in the hole.For the drill bit place loosened soil that may occur, before the high pressure pouring concrete of this implementing process method, earlier by plain slurry of spiral drill stamen pipe 51 downward cement injections, consolidation pile end loosened soil, concrete perfusion more thereafter, and begin to promote long screw auger tool 5, the lifting zero-time of immersed tube is later than the long screw auger tool, and makes augers be positioned at immersed tube 4 work all the time, finishes until concrete pouring, put into reinforcing cage then, last pile is handled.
