Description
Technical field
The utility model relates to technical field of buildings, particularly relates to a kind of bamboo steel pile tube.
Background technology
Steel pipe pile, be made up of steel pipe, grooved tenon joining, tongue and groove draw pin, the left end tube wall of diameter of steel tube vertically connects rabbet groove, the cross section of rabbet groove is the square frame-shaped of openings at one side, reinforcing rib is provided with in the side of rabbet groove, on the right-hand member tube wall of diameter of steel tube and partially radial location is vertically connected with tongue and groove pin, and the channel section of tongue and groove pin is I-shaped.
The selection of piling machinery will according to engineering landforms, geology, supporting vertical model, appearance and size, weight, the material of stake, specification and length of embedment, engineering quantity size, duration length etc. and determine.
During bridge is cast-in-place, part adopts limited bracket form of construction work, especially in Muddy Bottoms geology, and support processing form difficulty, especially bracket basis part.
And during traditional steel pipe pile construction, because the extrusion friction resistance of steel pipe pile and mud or mucky soil weak soil is little, side friction resistance and the end holding capacity of unit length are little, trouble when making to construct in mud, steel pipe pile is insecure.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of bamboo steel pile tube, effectively solve traditional steel pipe pile contact area level and smooth, frictional resistance is little with end holding capacity, makes construction trouble, the problems such as steel pipe pile is insecure.
Its technical scheme solved comprises spiral steel pipe, and steel pipe is provided with multiple evenly distributed annular plate, and floor is provided with multiple circumferentially uniform stiffened panel, and floor is provided with multiplely lets out hole.
The utility model structure is ingenious, and input cost is low, shortens drainage channel, improves and increases the frictional force of weak soil avris and the holding capacity of termination, and corresponding to decrease steel pipe pile long, reduces and drops into, and simultaneously due to the existence because of annular plate, improves uplift resistance.

Fig. 3 is the utility model top view.
Fig. 4 is the utility model annular plate and lets out hole schematic diagram one.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Provided by Fig. 1 to Fig. 4, the utility model comprises spiral steel pipe 1, and steel pipe 1 is provided with multiple evenly distributed annular plate 2, and floor 2 is provided with multiple circumferentially uniform stiffened panel 3, and floor 2 is provided with multiplely lets out hole 4.
The spacing of described every two annular plates 2 is 3 meters.
Described floor 2 is welded on steel pipe 1, and stiffened panel 3 is welded on steel pipe 1 and floor 2 junction.
Described stiffened panel 3 is triangular in shape.
Described let out the rounded or rectangle in hole 4.
Described let out hole 4 while overlapping with annular plate 2 inner edge.
When the utility model uses, the design feature of bamboo steel pile tube is exactly the steel plate annular plate 2 arranging the protrusion of wide about 10cm together on pile body steel pipe 1 every 3m, during construction, the mode such as back-up sand is filled gilled rings and is formed space, compacted and rubbing action is formed to mud and mucky soil weak soil, for increasing lateral area, improve and increase side friction.
During pile sinking, enlarged footing and rib (wing plate) form space, stake side sand and fill, and define the supporting steel pile tube that pile crown expands lateral irrigation sand.
When pile sinking, formation space, stake side sand is filled, and its advantage to shorten drainage channel, accelerates the diffusion of super interstitial hydraulic pressure and the consolidation of outside muddy soft soil layer, and improve weak soil side skin friction, replace former Pile side soil body, the collateral resistance of back-up sand is higher.Due to the effect of contraction of floor 2, the sand of filling to a certain degree with stake overall work, correspondingly add a footpath and side surface area, add the collateral resistance of stake.
By setting up hoop floor 2, stiffened panel 3 to common steel tube 1, letting out hole 4 equipment, form the steel pipe of similar ring.Under vibration during heavy construction, fill sandstone in surrounding, improve, improve side direction frictional resistance and the termination holding capacity of unit length to stake week mucky soil, corresponding to decrease steel pipe pile long, reduces input.The more identical geologic position of this engineering test reduce 30% long.Meanwhile, because ring (hoop floor) exists, uplift resistance can be improved.
The effect of annular plate 2 is the contacts area expanding pile foundation and soil around pile.Meanwhile, the existence of annular plate 2, improves soil property to sandstone and provides duct.Annular plate 2 width and link height are determined according to actual needs.
The effect of stiffened panel 3 ensures that floor 2 can drive sandstone to sink when being subject to high-drag.
The effect of letting out hole 4 is that the stake first forming link constantly clamp-ons soil around pile during the course, and form space, the sandy soil on upper strata are filled by letting out hole 4, ensures overall improvement.
Specifically first laterally increase on floor 2 when manufacturing and use and let out hole 4, increase sandy soil during to construct and let out passage, then welding annular plate 3 and stiffened panel 4 are on the steel pipe 1 of factory process, carry out construction lofting roughly for the first time, and rear preparation sand heap puts in place, the accurate setting-out in pile foundation position, sand drift is drawn over to one's side into high outside and low outside shape, starts vibrating hammer, along with steel pipe 1 sinks, around sandy soil are with sinking, adopt spade or wood to pull out etc. sandy soil are sent into settling zone in construction.
Construction should be noted before pile sinking, reserved certain back-up sand at periphery, avoided back-up sand deficiency to cause construction steel pipe pile driving construction to interrupt.
The utility model, relative to traditional normal spiral steel pipe pile, by structure design cleverly, adds avris frictional resistance, helping steel pipe pile more firm when constructing, constructing convenient, solving ordinary steel pile tube Problems existing in building field.
The utility model structure is ingenious, and input cost is low, shortens drainage channel, improves and increases the frictional force of weak soil avris and the holding capacity of termination, and corresponding to decrease steel pipe pile long, reduces and drops into, and simultaneously due to the existence because of annular plate, improves uplift resistance.
