Description
Technical field
This utility model relates to building field, more specifically, it relates to a kind of foundation pile.
Background technology
Cast-in-situ bored pile is the conventional pile-type of one that building foundation construction processes, and owing to it has the advantage such as easy construction, reasonable, the soil property strong adaptability of cost, is used widely in industry and all kinds of foundation construction such as civil buildings, bridge.
If publication number is a kind of mode that CN204125938U name is called disclosed in " the strong foundation pile of superelevation filled by waste residue ", have employed the mode of waste residue filling to improve the frictional force of foundation pile and soil property part, improve the bearing capacity of prefabricated pile, but owing to its pile body position is directly formed by Concrete Filled, thus cause that its intensity is not high.
Utility model content
The purpose of this utility model is to provide the foundation pile that a kind of pile strength is high and bearing capacity is strong.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of foundation pile, pile body including hollow, the bottom end face of described pile body is connected to end plate, at least one Grouting Pipe it is provided with in described pile body, the lower end of this Grouting Pipe is through end plate and fixes with end plate, the peviform frost boiling dish being arranged below being connected to bottom pile body in Grouting Pipe, the basin edge of peviform frost boiling dish is that spacing coordinates with pile body lower end, the first reinforcing bar being provided with annular permutation vertical in pile body, vertical on the first reinforcing bar of annular permutation it is arranged at intervals with the second reinforcing bar that multi-turn is fixing with the first reinforcing bar.
Pass through such scheme, by arranging the first vertical reinforcing bar and multi-turn in pile body in spaced second reinforcing bar of vertical direction, so that the structural strength of pile body is greatly enhanced and passes through to inject high pressure concrete slurry in Grouting Pipe, can discharge from the bottom of Grouting Pipe and fall to peviform frost boiling dish then again from the basin edge of peviform frost boiling dish and spilling the gap of pile body lower end, the bottom of pile body is encased, form the expansion head that outline is bigger than pile body, and then increase the attachment force between soil layer, it is finally reached the foundation pile that pile strength is high and bearing capacity is strong.
It is optimized for further: the opposite side of the described peviform relative pile body of frost boiling dish is provided with pile top.
By such scheme, by pile top, can be more prone to squeeze in soil layer in the process of piling.
It is optimized for further: the outer rim of described pile body is bigger along outer rim than the basin of peviform frost boiling dish.
Pass through such scheme, after piling, owing to the outer rim of pile body is bigger than the outer rim on basin edge, it is possible to make pile body and soil layer fit tightly compression, such that it is able to prevent pile body and space occurs between the hole that the pile top by peviform frost boiling dish is up to, and then occur that pile body is unstable.
It is optimized for further: between described peviform frost boiling dish and the bottom of pile body, adopt steel column to be connected.
Pass through such scheme, can so that the connection between peviform frost boiling dish and pile body becomes more firm by steel column, and after high pressure concrete slurry is drained into peviform frost boiling dish from Grouting Pipe, it is possible to overflow from peviform frost boiling dish smoothly thus forming the expansion head of the bottom wrapping in pile body.
It is optimized for further: the outer wall of described pile body is provided with the recessed groove extended along its length.
By such scheme, when when piling, the soil property being extruded is owing in bottom squeeze, can pass through recessed groove, it is possible to by recessed groove, unnecessary soil property is reversed discharge, so that piling becomes more smooth and easy.
It is optimized for further: the outer wall of described pile body is additionally provided with the annular protrusion along pile body length direction permutation.
It is optimized for further: the side ring limit bottom the relative pile body of described annular protrusion is provided with the chamfering down to pile body.
By such scheme, pass through annular protrusion, it is possible to increase the frictional force between pile body and soil layer, thus improving the ground connection firmness of foundation pile；And the side ring limit bottom relative for annular protrusion pile body is provided with the chamfering down to pile body, thus can be more smooth and easy when piling.
In sum, this utility model has the advantages that by being provided with the first reinforcing bar and the second reinforcing bar in pile body, so that the intensity of pile body is greatly enhanced；Again through Grouting Pipe and peviform frost boiling dish, Grouting Pipe is injected high pressure concrete slurry, can discharge from the bottom of Grouting Pipe and fall to peviform frost boiling dish then again from the basin edge of peviform frost boiling dish and spilling the gap of pile body lower end, the bottom of pile body is encased, form the expansion head that outline is bigger than pile body, and then increase the attachment force between soil layer, it is finally reached the foundation pile that pile strength is high and bearing capacity is strong.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model.
In the present embodiment, referring to accompanying drawing 1 and accompanying drawing 2, foundation pile mainly includes the pile body 1 of cylindrical, hollow, and in the bottom of pile body 1, envelope has end plate 3, is arranged below peviform frost boiling dish 5 at end plate 3, it realizes being connected with end plate 3 by steel column 4, and between basin edge and the end plate 3 of peviform frost boiling dish 5, there is gap, the outline of pile body 1 is bigger than peviform frost boiling dish 5, is additionally provided with at least one Grouting Pipe 2 in pile body 1, here selecting one, the bottom of this Grouting Pipe 2 is passed and is fixed on end plate 3；By injecting high pressure concrete slurry in Grouting Pipe 2, can discharge from the bottom of Grouting Pipe 2 and fall to peviform frost boiling dish 5 then again from the basin edge of peviform frost boiling dish 5 and spilling the gap of pile body 1 lower end, the bottom of pile body 1 is encased, form the expansion head that outline is bigger than pile body 1, and then increase the attachment force between soil layer.
Referring to accompanying drawing 3, the first reinforcing bar 61 of vertical annular permutation it is internally provided with at pile body 1, vertical on the first reinforcing bar 61 of annular permutation it is arranged at intervals with the second reinforcing bar 62 that multi-turn is fixing with the first reinforcing bar 61, thus improve the intensity of pile body 1, reach the effect of the foundation pile that pile body 1 intensity is high and bearing capacity is strong.
And the outer wall at pile body 1 is additionally provided with the annular protrusion 12 along pile body 1 length direction permutation, and in order to the side ring limit bottom the convenient piling relative pile body 1 of annular protrusion 12 is provided with the chamfering down to pile body 1, thereby through annular protrusion 12, considerably increase the degree of being connected firmly between foundation pile and soil property.
Further it is provided with, at the outer wall of pile body 1, the recessed groove 11 extended along its length, thus when piling, the soil property being extruded is owing to meeting is in bottom squeeze, by recessed groove 11, unnecessary soil property can be reversed discharge by recessed groove 11, so that piling becomes more smooth and easy.
