Abstract
The invention discloses an overall length core poring prestress pipe pile composite foundation. The overall length core pouring prestress pipe pile composite foundation comprises prestress pipe piles (1) and a broken stone cushion layer (3) laid on the tops of the prestress pipe piles (1), and pile cores (2) are poured in pile holes of the prestress pipe piles (1). According to the overall length core poring prestress pipe pile composite foundation, the overall strength of the prestress pipe piles is improved, the situation that due to the fact that underwater water seeps down along pipe bodies of the prestress pipe piles, the parts, at the pile ends, of the foundation are softened is avoided, and the overall length core poring prestress pipe pile composite foundation has a high bearing capacity and a deformation resisting capacity. The bearing capacity of the prestress pipe piles is improved, the bending resisting and shearing resisting capacity of the prestress pipe piles is improved, the stability of the prestress pipe piles in the foundation is improved, and the seismic performance is improved. Above all, by means of the overall length core poring prestress pipe pile composite foundation, the bearing capacity and the deformation resisting capacity of the composite foundation and the seismic performance of the prestress pipe piles are effectively improved, construction is easy and convenient, the application range is wide, the overall length core poring prestress pipe pile composite foundation is especially suitable for being used in 8-degree earthquake fortification areas, and the overall length core poring prestress pipe pile composite foundation is easy to popularize.
Description
Technical field
The present invention relates to construction implement technical field, relate in particular to a kind of total length and fill with core prestressed tubular pile composite foundation.
Background technology
In building construction process, conventionally adopt pile for prestressed pipe to increase the stability of ground, and then guarantee engineering safety.And high-strength Prestressed Pipe Pile is because its Compressive Bearing Capacity is large and durable resistance, be widely used in pile foundation and rigid pile composite foundation in soft foundation.
But, in work progress, exist because bending resistance, the shear strength (pile extension position) of pile for prestressed pipe are not high, and, owing to thering is a hole in the middle of pile for prestressed pipe, very easily make underground water along oozing under the pipe shaft of pile for prestressed pipe, softening pile end groundwork, makes its supporting capacity and non-deformability can not get fully even reducing; And pile for prestressed pipe is applied independently in ground, its anti-seismic performance is not high, is particularly restricted in the 8 degree regional applicability of providing fortification against earthquakes.
Therefore, how improving the anti-seismic performance of composite foundation supporting capacity, non-deformability and pile for prestressed pipe, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
In view of this, the invention provides a kind of total length and fill with core prestressed tubular pile composite foundation, in order to address the above problem, scheme provided by the invention is as follows:
A kind of total length is filled with core prestressed tubular pile composite foundation, comprising:
Pile for prestressed pipe, is perfused with a core in the stake hole of described pile for prestressed pipe; Be layed in the broken stone cushion layer on stake top;
Preferably, above-mentioned total length is filled with in core prestressed tubular pile composite foundation, and described broken stone cushion layer is arranged at top, described pile for prestressed pipe top.
Preferably, above-mentioned total length is filled with in core prestressed tubular pile composite foundation, and described stake core is plain concrete pile core.
Preferably, above-mentioned total length is filled with in core prestressed tubular pile composite foundation, and the length of described pile for prestressed pipe is identical with the length of described stake core.
Preferably, above-mentioned total length is filled with in core prestressed tubular pile composite foundation, and multiple described pile for prestressed pipe are matrix and arrange.
Preferably, above-mentioned total length is filled with in core prestressed tubular pile composite foundation, and the thickness of described broken stone cushion layer is 20cm～30cm.
Total length provided by the invention is filled with core prestressed tubular pile composite foundation, by be perfused with a core in the stake hole of pile for prestressed pipe, improve the bulk strength of pile for prestressed pipe and avoided underground water to cause the situation of softening pile end groundwork along oozing under the pipe shaft of pile for prestressed pipe, there is higher supporting capacity and non-deformability; And improve bending resistance and the shear strength of pile for prestressed pipe by stake hole filling core, effectively strengthened the anti-seismic performance of pile for prestressed pipe.Total length provided by the invention is filled with core prestressed tubular pile composite foundation, has effectively improved supporting capacity, non-deformability and the anti-seismic performance of composite foundation.
