Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to help understand the content of the present invention.
[0016] As shown in Figure 2, the pile foundation of the present invention protrudes a plurality of steel bars 3 outwards at the bottom of the cylindrical pile foundation body composed of concrete 2 and steel bars 3, and forms a large head-shaped chassis 4 at the bottom of the pile foundation body. The radial dimension of 4 is larger than the main body of the pile foundation. Due to the pressure effect of the soil above the chassis 4 and the shear force effect of the soil, the pile foundation has good pullout resistance in addition to good bearing pressure.
[0017] Since the reinforcing bar protrudes outwards from the bottom of the pile foundation, how to form it is the key and technical difficulty of the present invention. The invention also provides a pile forming method. The pr...
