Abstract
A novel major diameter prefabricated thin-walled cylinder/pipe pile. Major diameter prefabricated thin-walled cylinder/pipe pile containing inner support (partition sheet) is provided with a larger stiffness. As the existence of inner support, specifically the existence of full-length inner support, the contact area of cylinder/pipe pile and soil body has a large increase, in the major diameter prefabricated thin-walled cylinder/pipe pile with cover board, as the soil body in the cylinder is contacted in the construction process, the earth filling effect is increased, after adding the cover board, it also endures the terminal resistance provided by the compacted soil body, so that the bearing capacity of the cylinder/pipe pile obtains larger improvements. The major diameter prefabricated thin-walled cylinder/pipe pile containing inner support (partition sheet) has larger lateral stiffness and can also be used for horizontal retaining.
Description
Technical field
The utility model relates to the stake of a kind of cast-in-place large diameter thin wall tube, the thin-walled cylinder pile that especially a kind of diameter supports in having greater than 800mm.
Background technology
The stake of cast-in-place large diameter thin wall tube has bearing capacity height, advantage that cost is low, applied in the corresponding engineering technical field, but because its construction technology is cast-in-place, concrete curing needs the regular hour, so the duration is long slightly, the cast-in-situ cylinder pile concrete strength of pile is low, and the quality relative difficult guarantees, moreover because the soil body in the tube does not have densification, the end resistance that the soil body provides in the tube is limited.In order to remedy above deficiency, adopt the prefabricated large diameter thin wall tube/pile tube that forms of strong concrete to be invented, but this new type tube/pile tube also comes with some shortcomings, as major diameter prefabricated thin-wall tube/pile tube is big owing to diameter, wall thin, make that its rigidity is less, stake is in the process that is pressed into or squeezes into, if it is excessive to apply the power of being pressed into, major diameter prefabricated thin-wall tube/pile tube is easy to destroy.
Summary of the invention
At the deficiencies in the prior art, the invention reside in provides a class to contain the major diameter prefabricated thin-wall tube/pile tube (following or title tube stake) of interior support (dividing plate) to strengthen tube/pile tube rigidity, and concrete strength of pile is greater than C50.
If the major diameter prefabricated thin-wall tube/pile tube that has interior support (dividing plate) 2 is plate 3 not with cover, as Fig. 1, shown in Figure 3, interior support (dividing plate) 2 can be prefabricated in the factory with a tube pile lining 1 and form, supporting (dividing plate) 2 in guaranteeing is a rigid unitary structure with a tube pile lining 1, thereby guarantees that the tube stake has bigger rigidity, globality preferably.
If the major diameter prefabricated thin-wall tube/pile tube that has interior support (dividing plate) 2 is plate 3 with cover, as Fig. 2, shown in Figure 4, cover plate 3 rigidly connects with tube pile lining 1, interior support (dividing plate) 2 can be prefabricated in the factory with a tube pile lining 1 with cover plate 3 and form, guarantee that cover plate 3, interior support (dividing plate) 2 are a rigid unitary structure with a tube pile lining 1, thereby guarantee that the tube stake has bigger rigidity, globality preferably.
Cover plate various informative, i.e. plectane, but also box out on the plate, also can stay a plurality of holes on the cover board different positions.
Support the various informative of (dividing plate) in the major diameter prefabricated thin-wall tube, as shown in the figure, its length both can be highly the same with the tube stake long, and that also can make is very short.Tube stake cross section such as Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5.
More than new type tube/the pile tube bending rigidity is big, horizontal bearing capacity is improved, and except that being used for vertical pressure-bearing, also can be used for a laterally retaining.
The major diameter prefabricated thin-wall tube that has cover plate among the present invention is owing to the soil body in the tube in work progress obtains densification, and because the existence of interior support (dividing plate), especially support the existence of (dividing plate) in elongated, the outside, interior support (dividing plate), cover plate all contact with the soil body in the tube pile lining, make the tube stake and the contact area of the soil body increase greatly, the soil body obtains densification, soil plug effect increases, frictional resistance increases, cover plate also bears the bigger end resistance that the densification soil body is provided, and makes the tube pile capacity be greatly improved.
Concrete production can be passed through the pretensioned prestressing technology, through the high speed centrifugation moulding process, makes by secondary is steam-cured.
