Abstract
The utility model discloses a vertical load bearing pile with a buoyancy pontoon for a pile foundation wharf. A circular pipe pile body made of steel is composed of a pile head section, an in-water section and an earth penetrating section, wherein the in-water section of the pile body is provided with a concentric and circular outer sleeve barrel of which the diameter is 2 to 8 times of the diameter of the pile body, both ends of the sleeve barrel are connected with the pile body via taper panels, and a sealing cabin is formed by the sleeve barrel and the pile body. A through hole which can be opened and closed is arranged on a connecting plate of taper surfaces at both ends, and a transversal and a vertical connecting support plates or support rods are arranged between the walls of the sleeve barrel and the pile body. The utility model can effectively improve the vertical load bearing force of a pile by buoyancy supplied by a buoyancy pontoon of the in-water pile body section, and have simple and convenient operation.
Description
Technical field
The utility model relates to the vertical bearing peg of the band floating drum of using in a kind of pile foundation wharfs.Belong to the building structural member in harbour, seashore and the ocean engineering field.
Background technology
Vertical bearing peg is used very extensive in harbour, seashore and ocean engineering, as pile foundation wharfs, pile foundation ocean platform etc., and the vertical bearing capacity that provides of single pile foundation from hundreds of tons to nearly two kilotons.Stake for large bearing capacity is generally the stake of steel pipe, and diameter is more than 1m, and embedded depth reaches 30m～50m.Improve the bearing capacity of stake, the general method that adopts is the diameter that increases stake, perhaps increases the length of stake, and these two kinds of methods need increase the material usage of stake on the one hand, and the power of driving piles on the other hand also will strengthen, and can cause making the increase of stake and piling expense.Cross when thick or long when stake, piling is also had any problem.
Require the bearing capacity of pile foundation bigger in the large-sized deep water pile foundation wharfs, and the free section that this pile foundation is in water is longer, if the pile cutoff volume that is in water is strengthened, makes it that buoyancy is provided, and so just can increase the vertical bearing capacity of stake.
Summary of the invention
The purpose of this utility model is to provide the vertical bearing peg of the band floating drum that a kind of pile foundation wharfs use, and the buoyancy that the floating drum by the pile body section provides can improve the vertical bearing capacity of stake effectively.
For achieving the above object, the utility model is realized by following technical proposals: the vertical bearing peg of the band floating drum that pile foundation wharfs are used, the pipe pile body of steel is made up of pile crown section, water stage casing and the section of burying, it is characterized in that, being shaped on a diameter in pile body water stage casing is 2～8 times concentric circles outer sleeve of pile body diameter, the two ends of sleeve are connected with pile body with the circular cone panel, sleeve and pile body constitute a sealed compartment, but on the taper seat junction plate at two ends, be provided with the through hole of switch, between sleeve wall and pile body, be provided with horizontal with vertical gripper shoe or the support bar of being connected.
Superiority of the present utility model is: the buoyancy that the floating drum by water king-pile figure provides can improve the vertical bearing capacity of stake effectively, is easy to implement.
Description of drawings
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a cross-sectional drawing of the present utility model.
1 is the pile crown section among the figure, and 2 is water king-pile figure, and 3 is outer sleeve, and 4 are the section of burying, and 5 is bottom through-hole, and 6 is bottom taper seat junction plate, and 7 is vertical junction plate, and 8 is cross connecting plate, and 9 is nose-circle conical surface junction plate, and 10 is the top through hole.
The specific embodiment
An embodiment is as follows for the utility model: the vertical bearing peg of the band floating drum that pile foundation wharfs are as depicted in figs. 1 and 2 used, constitute by steel pipe pile body and outer sleeve, outer sleeve surrounds water king-pile figure, the bottom of sleeve all is connected with pile body with the taper seat steel plate with the top, make and constitute a sealed compartment between pile body and the sleeve, but be provided with the through hole of switch at the top of the bottom of bottom taper seat junction plate and nose-circle conical surface junction plate, between pile body and sleeve, be provided with 3 layers every layer 4 totally 12 vertical rectangle junction plates and 4 layers every layer 4 totally 16 horizontal fan-shaped junction plates.
Above-mentioned pipe pile body diameter 1.4m, the long 20m of water king-pile figure, segment length 28m buries, outer sleeve diameter 6m, each 2m of taper seat height of top and bottom, middle outer sleeve height 16m, this is arranged in the mixing ground of argillic horizon and sandy soil layer, the vertical design bearing capacity that the section of burying of stake provides is about 6000kN, the buoyancy that is produced by floating drum is about 4630kN, and then the general design bearing capacity of this stake is 10630kN, 77% of the bearing capacity that the bearing capacity that buoyancy provides provides for the pile foundation section of burying, when the outer sleeve enlarged diameter, this ratio can also improve.As seen the buoyancy of floating drum can account for higher ratio in the vertical bearing capacity of stake.
Because the inaccuracy of soil body parameter, when using the vertical bearing capacity that the section of burying of stake provides in the design, the safety factor that essential consideration is 2～3 times, when bearing dynamic load, this safety factor is taller.And the vertical bearing capacity that buoyancy provides is determined, need not consider safety factor during use.For the vertical bearing capacity that requires to provide big and conventional stake when being difficult to meet the demands, it is very effective utilizing the utility model stake.Can increase material usage though build floating drum, provide under the situation of equal vertical bearing capacity, the vertical bearing peg of band floating drum is shorter than the segment length of burying of conventional stake, or pile body diameter is little, so also saves the part material, and piling is also easy in addition.After sleeve and junction plate were established in the pile body outside in water in addition, the bending resistance of pile body was strengthened, and the wall thickness of top pile body or diameter also can reduce significantly.These all can make the increasing degree of the utility model pile material consumption reduce.
In the piling construction process, the through hole of top and bottom is opened, allow water enter in the floating drum, do not increase the difficulty of piling like this.After piling put in place, perhaps the stake effect of going up had after certain vertical load, inflates in floating drum by the through hole on top, and the water in the floating drum is extruded from bottom through-hole, after the water to the floating drum all is excluded, the through hole of top and bottom was closed sealing.
Claims (1)
1. the vertical bearing peg of the band floating drum used of pile foundation wharfs, the pipe pile body of steel is made up of pile crown section, water stage casing and the section of burying, it is characterized in that, being shaped on a diameter in pile body water stage casing is 2～8 times concentric circles outer sleeve of pile body diameter, the two ends of sleeve are connected with pile body with the circular cone panel, sleeve and pile body constitute a sealed compartment, but are provided with the through hole of switch on the taper seat junction plate at two ends, are provided with horizontal with vertical gripper shoe or the support bar of being connected between sleeve wall and pile body.
