Specific implementation mode
Embodiment 1
As shown in Figure 1, the concrete support pile layout in a kind of foundation pit, includes the concrete support pile 1 of various shapes, in 4 phase of foundation pit
Adjacent two sides structure at an acute angle or a right angle when, it is circular first concrete support pile that horizontal cross-section is provided on the outside of this angle
101；When the adjacent two sides of foundation pit 4 constitute obtuse angle, second that horizontal cross-section is polygon is provided on the outside of this angle
Concrete support pile 102, the angle of foundation pit 4 and the side of polygon are oppositely arranged；It is that third concrete support pile is arranged in smooth place in foundation pit 4
103, width of the third concrete support pile 103 close to soil layer side is not less than the side far from foundation pit 4.The outer edge of concrete support pile 1
It is smooth shape.The density of 4 corner's concrete support pile 1 of the foundation pit is more than the density for the concrete support pile 1 smoothly located.
Wherein the first concrete support pile 101, the second concrete support pile 102, third concrete support pile 103 are column structure, concrete branch
Fender pile 1 includes basalt fibre arrangement of reinforcement 2 and steel arrangement of reinforcement 3.The density of basalt fibre arrangement of reinforcement 2 of the concrete support pile 1 at soil layer
More than the concentration of any position far from soil layer, basalt fibre arrangement of reinforcement 2 and steel arrangement of reinforcement 3 are arranged alternately, are respectively provided at arc profound
Military rock fiber arrangement of reinforcement 2 ensures the anti-crack ability of concrete support pile 1 in the case where saving resource.
As Figure 2-3, third concrete support pile 103 is not less than close to the sectional area of soil layer side vertical direction far from soil layer
Any position vertical direction sectional area, in this embodiment third concrete support pile 103 from close to soil layer to far from soil layer
On direction, the vertical sectional area of concrete supporting 1 is gradually reduced, and specifically, 103 upper surface of third concrete support pile is trapezoidal portion 11
It is replaced with the tangent arc in two sides with the upper bottom edge of the combination of curved portion 12, trapezoidal portion 11, bottom is close to soil layer.It is trapezoidal
