Description

Building pile foundation

Technical Field

The application relates to the technical field of building construction, in particular to a building pile foundation.

Background

At present, in the building construction process, a softer and weaker foundation needs to be reinforced, common precast piles and cast-in-place piles have the problem of poor bearing capacity, when the common precast piles and cast-in-place piles bear the pressure of the top, bending stress can be generated, and when the stress is overlarge, pile bodies can be broken, so that the bearing capacity is weakened.

SUMMERY OF THE UTILITY MODEL

For solving above-mentioned technical problem, this application provides a building pile foundation, which comprises a body, the body has first base member, transition body and second base member from last to down, first base member with the second base member all has concave arc global to the outside, the external diameter of the transition body is greater than first base member with the external diameter of second base member, the upper surface of the transition body is equipped with the arch of loop configuration, the dead lever of a plurality of cone structures is all established to the lower surface of the transition body.

Optionally, the first base body, the transition body and the second base body are integrally formed.

Optionally, the fixing rods are uniformly arranged along the circumferential direction of the transition body.

Optionally, the protrusion has an arc-shaped structure along the cross section.

Optionally, the bottom end of the fixing rod is located below the bottom of the second base.

Optionally, the circumferential surface of the transition body is an arc-shaped surface.

Use the technical scheme of this application, first base member and second base member all have concave arc global to the outside, the transition body sets up in the middle of first base member and second base member, and the external diameter of the transition body is greater than the external diameter of first base member and second base member, can increase the area of contact of body and soil, reduce the pressure that the unit area receives, the bearing capacity of body has been increased, the protruding area of contact with soil that can further increase of transition body upper surface, can play the effect of consolidating the transition body simultaneously, the dead lever of transition body lower surface inserts in soil, the area of contact of body and soil has been increased, the steadiness of body has been improved.

Detailed Description

As shown in fig. 1-4, the building pile foundation provided by the embodiment of the present application includes a body, and the body includes, from top to bottom, a first base body 1, a transition body 2, and a second base body 3. Wherein, first base member 1 and second base member 3 all have concave arc global to the outside, and the external diameter of transition body 2 is greater than the external diameter of first base member 1 and second base member 3, and the upper surface of transition body 2 is equipped with the arch 4 of loop configuration, and the dead lever 5 of a plurality of tapered structures is all established to the lower surface of transition body 2.

In this embodiment, first base member 1, transition body 2 and second base member 3 integrated into one piece to first base member 1 global 11, second base member 3 global 31 and transition body 2 global 21 are the arc structure, can effectual increase the area of contact of body and soil, and then reduce the pressure that unit area received, have improved the bearing capacity and the steadiness of body.

Specifically, the fixing rods 5 are uniformly arranged along the circumferential direction of the transition body 2, and the bottom ends 51 of the fixing rods 5 are located below the bottom of the second base body 3, so that the fixing rods 5 can effectively improve the stability of the body.

Specifically, the protrusion 4 of the annular structure is in an arc-shaped structure along the cross section.

During the use, first base member and second base member all have concave arc global to the outside, the transition body sets up in the middle of first base member and second base member, and the external diameter of the transition body is greater than the external diameter of first base member and second base member, can increase the area of contact of body and soil, reduce the pressure that the unit area receives, the bearing capacity of body has been increased, the protruding area of contact with soil that can further increase of transition body upper surface, can play the effect of consolidating the transition body simultaneously, the dead lever of transition body lower surface inserts in the soil, the area of contact of body and soil has been increased, the steadiness of body has been improved.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
