Abstract
The utility model relates to a large-diameter steel pipe foundation pile with a grouting accessory, and aims to provide the large-diameter steel pipe foundation pile, with the grouting accessory, which is provided with the grouting accessory, simple in structure and convenient to manufacture so as to effectively improve lateral stiffness of the foundation pile, increase pile shaft resistance, and reduce settlement. According to the technical scheme, the large-diameter steel pipe foundation pile with the grouting accessory is characterized in that a plurality of small grouting pipes are evenly arranged on the outer wall of the large-diameter steel pipe foundation pile, the grouting pipes are welded along the large-diameter steel pipe foundation pile in an axial total length mode, and grouting holes are formed in the outer sides of the grouting pipes at intervals. The large-diameter steel pipe foundation pile with the grouting accessory is suitable for the technical field of sea geotechnical engineering of sea structure foundation base construction, and is also suitable for the basic technical fields of hydraulic engineering and port navigable engineering foundations.
Description
Technical field
The utility model relates to a kind of large diameter steel pipe foundation pile of being furnished with the slip casting accessory.Be applicable to the ocean geotechnical engineering technical field that the marine structures foundation is built, also be applicable to hydraulic engineering, port navigation engineering foundation basic technology field.
Background technology
Marine resources development all is devoted to develop in countries in the world, marine petroleum exploitation, wind-powered electricity generation energy construction etc. all depend on the safety and stability of foundation, horizontal power load actions such as the marine structures structure mainly is subjected to morning and evening tides, surges, wind-force, earthquake, marine facies soil body ground weakness in addition, its basic supporting capacity, stability and safety all should be protected.Marine structures is built more application large diameter steel pipe single pile form, and single pile form of structure integral rigidity is on the low side, and supporting capacity and long-time stability under the horizontal dynamic load effect are had relatively high expectations.
Summary of the invention
The technical problems to be solved in the utility model is: at the problem of above-mentioned existence, provide a kind of simple in structure, easily manufactured large diameter steel pipe foundation pile of being furnished with the slip casting accessory, to improve the anti-side rigidity of foundation pile effectively and to increase pile side friction, reduce sedimentation.
The technical scheme that the utility model adopted is: a kind of large diameter steel pipe foundation pile of being furnished with the slip casting accessory, it is characterized in that: evenly arrange some small-sized Grouting Pipe at large diameter steel pipe foundation pile outer wall, Grouting Pipe is welded along described large diameter steel pipe foundation pile entire axial length, and injected hole is offered in the described Grouting Pipe outside at a certain distance at interval.
Described injected hole parcel rubber sealing leather sheath.
Described Grouting Pipe bottom section dwindles gradually, is tip-shape.
Described Grouting Pipe has 6, and the angle of the adjacent two Grouting Pipe centers of circle and described large diameter steel pipe foundation pile circle center line connecting is 60 °.
The beneficial effects of the utility model are: 1) Grouting Pipe and large diameter steel pipe foundation pile form the overall structure acting in conjunction, upper component are installed do not exert an influence, as sectional dimension and the integral rigidity that member has increased foundation pile forever is set.2) length of Grouting Pipe and injected hole are offered situation and are carried out prefabricatedly according to stratum, ocean survey information, do not influence programming.3) Grouting Pipe has the whole mechanical characteristic of raising and the double function of slip casting, many Grouting Pipe can be guaranteed combining closely of slurry and inter-pile soil around arranging during slip casting, in addition silt and sand in the Yu Haiyang stratum are carried out high-pressure slip-casting also for administering the effective measures of liquefaction.

The specific embodiment
As Fig. 1 ~ shown in Figure 3, evenly arrange 6 small-sized Grouting Pipe 2 at large diameter steel pipe foundation pile 1 pile body periphery in the present embodiment, adjacent two Grouting Pipe 2 centers of circle and large diameter steel pipe foundation pile 1 circle center line connecting angle are 60 °.Grouting Pipe 2 is connected with the welding manner total length with large diameter steel pipe foundation pile 1, along the welding of Grouting Pipe 2 bilateral symmetry, determines weld size according to designing requirement, guarantees to form overall structure and plays a role jointly.
Grouting Pipe 2 is made by steel pipe in this example, and the cross section dwindles pointedly gradually from top to bottom, and Grouting Pipe 2 length can or not wait with large diameter steel pipe foundation pile 1 equal in length, determine according to the slip casting soil depth.Grouting Pipe 2 outsides are provided with injected hole 201 at a certain distance at interval, injected hole 201 outer wrapping rubber sealing leather sheath, and injected hole 201 is provided with scope and determines according to slip casting soil layer projected depth.
Concrete construction sequence is: as Fig. 4, shown in Figure 5, and after large diameter steel pipe foundation pile 1 is squeezed into design attitude together with 6 Grouting Pipe 2, injected hole 201 degree of depth this moment powder soil horizon 6 and sand layer 7 scope in the stratum, ocean.Grouting Pipe 2 tops link to each other with high-pressure injection pump 5, start high-pressure injection pump 5 beginning slip castings, and make slurries infiltrate the soil body along the splitting slit and fill the space, and compaction pile side soil, when reaching, slip casting stops stopping behind operating pressure or the design flow rate of grouting.
High-pressure slip-casting makes slurry combine with the soil body by effects such as infiltration, splitting, compacted, fillings, can improve the anti-side rigidity of foundation pile effectively and reduce sedimentation, greatly improve ocean soil layer mechanical characteristic, particularly for ocean soil layer medium sand soil layer and powder soil horizon, sidewall frictional resistance loss in the work progress between itself and foundation pile is maximum, when improving soil body mechanical property by grouting behind shaft or drift lining, also can increase pile side friction, cement belongs to hydraulic material in the slurries in addition, effect is better in the geotechnical engineering of ocean, and construction quality can be guaranteed.
