Pile foundation top is connected using inverse flange with top steel pipe pole, without foundation bolt, ensure that the smooth of precast concrete block
Installation.Steel pipe pile body can be considered basic arrangement of reinforcement, bear the most moments of flexure in basis, exterior pre-cast concrete block can not arrangement of reinforcement or
Few arrangement of reinforcement, while design and also do not limited by component steel ratio, element bearing capacity compared with reinforced concrete foundation can improve 30% with
On.
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Brief description of the drawings
Fig. 1 is the steel-pipe pile body construction schematic diagram of the present embodiment；
Fig. 2 is the weight type steel pipe pile foundation structural representation of the present embodiment.
Embodiment
As shown in Figure 1-2, a kind of transmission line of electricity is from the weight type steel pipe pile foundation of vertical rod, including steel pipe pile body 1, and
Several precast concrete blocks 2 in steel pipe pile body 1 are set in, the bottom of the steel pipe pile body 1 is provided with a steel plate 3, described
Steel plate 3 is used to carry each precast concrete block 2, and the concatenation of precast concrete block 2 in steel pipe pile body 1 forms counterweight group, weight
Precast concrete cushion cap 5 is arranged with the top of code character, the top of steel pipe pile body 1 is provided with flange 6, and the flange 6 is located at steel pipe
