As a person skilled in the art, the above square pole hole should be set at On the upper stack body, that is, the square pole hole is only opened on the top stack body or on the top few stack bodies, such as when opened on the top few stack bodies, when After the stacking body is stacked, the square pole holes on the corresponding stacking body are connected to form a deeper hole for embedding the bottom of the square pole.

The above shear connectors are used to avoid relative movement in the horizontal direction or relatively large displacement in the horizontal direction by providing shear stress when adjacent piles move relative to each other or have a tendency to move relative to each other in the horizontal direction. In this way, the stability of the foundation body structure can be ensured, and the pile-up body can be avoided when excessive force in the horizontal direction is transmitted from the square bar to the foundation body or when the soil on the side of the foundation body exerts an excessive extrusion force on the foundation body. Serious misalignment affects the position accuracy of the square pole in the distribution network line.

In this scheme, the basic body used to erect the square pole is formed by stacking multiple piles. In this way, the piles can be prefabricated before installation. During the field construction of the distribution network line, the piles can be stacked The body is stacked and installed in the pre-dug ground hole from bottom to top in order to quickly complete the overall forming of the basic body, and then, by inserting the square rod into the hole of the square rod, the installation of the square rod on the basic body is completed.
