A kind of pile foundation shield-tube embedment creeps into all-in-one with stake holes
Technical field
The present invention relates to a kind of pile foundation shield-tube embedment being applied to building pile foundation engineering device field and creep into all-in-one with stake holes.
Background technology
During building pile foundation engineering construction, often to carry out under different geological conditions.When running into soft geology, if this geological stratification is thicker, in boring procedure or after pore-forming, collapse hole phenomenon often occurs.The problem collapsed to solve stake holes to collapse, building pile foundation construction uses holing with slurry wall protection or tiretube process boring to construct.But the problem that holing with slurry wall protection or tiretube process drilling construction all exist self, specifically: during holing with slurry wall protection, substantial amounts of discarded slurry can be produced, not only pollute construction site, also surrounding can be affected, meanwhile, cleaning discarded slurry or administer the work such as contaminated environment and can cause again the increase of construction cost;During tiretube process boring, sleeve pipe is pressed in stratum by many employing machinerys, and in the easy off normal of process of press in middle sleeve, inclination, and the length of press-in sleeve pipe can not be long, and general 4-6m is advisable, time oversize, and press-in difficulty, and be not drawn out easily, will also result in the waste of sleeve pipe.
Therefore, for at mud, the most miscellaneous bury fast drilling pore-forming in the soft geology layers such as soil layer, silt, sand, clay or a small amount of gravel soil, during building pile foundation construction, it is required for loose and soft surrounding rock to develop one and be able to ensure that hole quality, avoid collapse hole, the most do not pollute construction site, the construction machinery of engineering-environment and construction method simultaneously.

With reference to accompanying drawing 1-4, the present invention provides a kind of pile foundation shield-tube embedment to creep into all-in-one with stake holes, including bearing system, drilling system, shield-tube embedment system, conduit promotes system, described bearing system includes base plate 1, column 2, described drilling system includes air-compressor set, boring rod set 3, revolving gear 4, drill bit 5, described air-compressor set includes air compressor machine 6, air accumulator 7, described air-compressor set is fixed on described base plate 1, described air compressor machine 6, air accumulator 7 is connected with the top of described boring rod set 3 by pipeline, described revolving gear 4 is fixed on described column 2 by guide rail, described boring rod set 3 includes drilling rod 31 of holing, shield-tube embedment drilling rod 32, described boring drilling rod 31 links with described drill bit 5 moveable hinge, convenient dismounting.
Described shield-tube embedment system includes that casing 8, casing union joint 9, described casing 8 include that inwall 81, outer wall 82, described casing union joint 9 are connected with described casing 8 by hoop screw thread 10, and the outer wall of described first joint casing 8 is provided with steam vent.
Described shield-tube embedment drilling rod arranges 32 between described boring drilling rod 31 and described casing union joint 9, and the inwall of described shield-tube embedment drilling rod 32 is provided with high-pressure blast hidden pipe, and described high-pressure blast hidden pipe is connected with described casing union joint 9 by connecting tube.High-pressure blast enters the hollow layer of described casing 8 from the high-pressure blast hidden pipe of described shield-tube embedment drilling rod 32, discharges from the steam vent of casing 8 outer wall, forms air curtain.
Described conduit promotes system and includes hoist engine 11, is mounted with the conduit of armored concrete, described hoist engine 11 is fixed on described base plate 1, described hoist engine 11 is connected with described conduit by steel wire rope, it is exactly specifically that described steel wire rope is connected with described conduit by the fixed pulley 12 being fixed on described column 2, coordinate filling concrete operation, it is achieved conduit extract work.
The bottom of described shield-tube embedment drilling rod 32 is connected with described casing union joint 9, and the top of described casing union joint 9 links with described shield-tube embedment drilling rod 32 moveable hinge.The casing union joint 9 of different size can be made as required, be correspondingly furnished with the drill bit 5 of multiple different-diameter, model, to adapt to different construction environments.
Described casing 8 is two-wall hollow structure, being provided with connection rib between described casing 8 double-walled, described casing 8 is merogenesis structure, and first joint casing 8 bottom is provided with cutting shoe, top is provided with hoop screw thread 10, and middle casing 8 upper and lower is respectively equipped with the hoop screw thread 10 cooperated.
Described casing union joint 9 is correspondingly arranged on interior tapered screw thread with described casing 8 junction, and described casing union joint 9 is both arms hollow structure, and the structure of described casing union joint 9 is corresponding with the structure of described casing 8.
Preferably, the bottom of described base plate 1 is provided with mobile crawler belt 13.Described mobile crawler belt 13 disclosure satisfy that a lot of complicated landform, enhances described pile foundation shield-tube embedment and stake holes and creeps into the adaptive capacity to environment of all-in-one.
A kind of pile foundation shield-tube embedment and the stake holes using the present invention to provide creeps into all-in-one when carrying out operation, is embodied in: before 1. using drill bit 5 perforate, pre-plugged casing 8, is connected with casing 8 by casing union joint 9.
2. opening air Compressor unit air feed, shield-tube embedment drilling rod 32 rotates simultaneously, makes casing 8 rotate underground of submerging.
3., after completing to bury a joint casing 8 underground, close air compressing device, rotate backward casing union joint 9, casing union joint 9 is unloaded, makes second section casing 8 be connected with casing union joint 9, the casing 8 that alignment has been installed, rotate forward second section casing 8, make upper and lower joint casing 8 be connected.
4. being again turned on air compressing device, shield-tube embedment drilling rod 32 rotates into downwards, buries second section casing 8 underground, is similar to this, buries more piece casing 8 underground.
When the most all casings 8 bury the degree of depth needed underground, close air compressing device, casing union joint 9 is unloaded, boring drilling rod 31 is connected with drill bit 5, start to creep into.
6. after being drilled into bottom casing 8, repeat the above steps 3 again, again bury casing 8, then repeat the above steps 4 underground, again hole, the most alternately, up through soft geology layer.
7., after pore-forming, irrigate underwater pile concrete, during concrete embedment 5-6m, start to rotate casing 8, withdrawing certain altitude, then, concrete perfusion is with withdrawing casing 8 alternately, until completing pile foundation, when extracting casing 8, it should conveying high-pressure wind coordinates the withdrawing of casing 8.
When pile foundation shield-tube embedment and the stake holes that the present invention provides creeps into all-in-one boring, can according to different stratum, taking flexibly first holes bury casing 8 afterwards underground or first bury casing 8 underground after the construction technology of boring.The pile foundation shield-tube embedment that the present invention provides and stake holes creep into all-in-one, solve the easy collapse hole of pile foundation boring and casing 8 buries problem long, that cannot extract waste material underground, it is adaptable to the pile foundation construction of all kinds of soft geologies.
