Abstract
The utility model discloses a pedestal pile for foundation construction of a transformer substation, which comprises a hollow concrete pile. A hollow expanded toe is arranged at the lower end of the concrete pile and filled with building materials, and the concrete pile is arranged on a designed soil layer, the expanded toe is arranged on a pile-end bearing layer. Further, the expanded toe is filled with common building materials such as slurry, mortar and the like, or is filled with waste building materials such as concrete aggregates, brick aggregates and the like. The pedestal pile is particularly suitable for regions with loose soil. By means of jet-grouting expanding construction, the strength of the soil layer at the end of the concrete pile can be increased greatly, end resistance of the concrete pile can be enhanced greatly, advantages of high-intensity of the body of the concrete pile and high end resistance thereof are functioned and combined sufficiently so that pile top load can be transmitted to the soil layer at the end of the concrete pile effectively, and effects on reducing pile top sedimentation and improving bearing capacity are evident.
Description
Technical field:
The utility model relates to a kind of buildings pile, particularly relates to a kind of transformer station capital construction expanded bore pile, belongs to the realm of building construction.
Background technology:
Along with the development of modern economy, the progress of society, the scale and the territorial scope of transformer station's infrastructure constantly enlarge, and the degree of depth that ground is handled also continues to increase, and pile foundation is as a kind of deep foundation, and it adopts rate also to improve constantly.Concrete pile is a kind of rigid pile, but when soft clay area is used, often to pass thicker mud, pile side friction is on the low side, it is less than normal to add stake end soil body modulus of compressibility, and concrete pile often loses supporting capacity because of sedimentation is excessive, can not give full play to the high advantage of self intensity, supporting capacity is limited, so its range of application is restricted.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of transformer station capital construction expanded bore pile is provided, satisfy the requirement of soft soil property bearing capacity.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of transformer station capital construction expanded bore pile comprises the concrete pile of hollow, and described concrete pile lower end is provided with the enlarged footing of a hollow, the inner constructional materials of filling of enlarged footing; Described concrete pile is positioned at the soil layer design level, and described enlarged footing is positioned at bearing course at pile end.
The inner filling of described enlarged footing used constructional materials always, as slurries, mortar.
The inner construction waste material of filling of described enlarged footing is as concrete particle, brick particle.
Good effect of the present utility model is:
1, the utility model not only can be filled hole, enlarged footing cave with slurries, mortar, gravel, can also use broken concrete, the filling in the lump of brick fragment associating cement paste, not only the purpose that discarded object utilizes again can be reached, the intensity of enlarged footing itself can also be well improved.
2, the utility model can make concrete pile stake end soil layer intensity strengthen greatly, increase substantially the end resistance of concrete pile, give full play to the high advantage of concrete pile pile strength, fully in conjunction with concrete pile self intensity height and the big advantage of end resistance, make pile top load be delivered to stake end soil layer effectively, reduce a top sedimentation and improve bearing capacity, effect is obvious.
3, the utility model is particularly suitable for the area that the soil is porous, in these areas, expands the bottom application worker by churning, can make full use of the advantage of big end bearing, thereby can meet or exceed the designing requirement of bearing capacity.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Referring to Fig. 1, a kind of transformer station capital construction expanded bore pile, comprise the concrete pile 1 of hollow, described concrete pile 1 lower end is provided with the enlarged footing 2 of a hollow, the enlarged footing 2 inner constructional materialss of filling; Described concrete pile is positioned at the soil layer design level, and described enlarged footing 2 is positioned at bearing course at pile end.
Described enlarged footing 2 inner slurries, these constructional materialss commonly used of mortar, perhaps fill concrete particle, these construction waste material of brick particle of filling.
This utility model is particularly suitable for the area that the soil is porous, in these areas, expands the bottom application worker by churning, can make full use of the advantage of big end bearing, thereby can meet or exceed the designing requirement of bearing capacity.
