The fence upright post can be obtained by adopting the following construction method, and the construction method comprises the following steps: a, excavating an underground foundation pit, excavating the underground foundation pit downwards along the designed position of the upright column with the depth of more than 800cm, excavating a sinking groove in an expanded manner towards the periphery at the upper end of the foundation pit, and arranging a layer of broken stone cushion (about 50 mm) at the bottom of the foundation pit; b, pouring the foundation after the foundation pit is dug, embedding two vertical rows of reinforcing steel bars in the foundation during pouring, arranging the two vertical rows of reinforcing steel bars along the front-back direction and arranging the two vertical rows of reinforcing steel bars at left and right intervals, exposing the upper ends of the two vertical rows of reinforcing steel bars out of the foundation and serving as the foundation of a reinforcing steel bar net rack in the stand column, and leveling the upper end surface of the foundation; c, transversely welding or binding a plurality of transverse steel bars on the two vertical steel bars to form a steel bar net rack (when the vertical steel bars are not high enough, the vertical steel bars are welded upwards to the height of the upright posts); d, enclosing four panels on the upper surface of the foundation outside the reinforcing steel bar net rack to form a section of the column section at the lowest part of the column, leveling the upper end surfaces of the four panels, and keeping the outer edges of the four panels aligned and in a tight state; an inner cylinder is arranged between two rows of reinforcing steel bar net racks in the section of the upright post; e, repeating the step d, and butting and arranging the next section of the upright column above each section of the upright column, wherein an inner cylinder is arranged in each section of the upright column and is butted with the lower inner cylinder until the height of the upright column of the enclosure is required; f, pouring a concrete structure in an inner cavity formed by all the upright post sections and the inner cylinder body at one time, and pouring a steel bar net rack in the inner cavity; g, crushing construction waste, filling the construction waste into the inner barrel, and covering the top cover before concrete solidification to complete the construction of the enclosure upright post.

In the method, the outer structure of the upright column body is obtained by splicing the panels section by section upwards, and concrete is poured once again to prepare the upright column; the construction defect that vertical dislocation is difficult to align due to the adoption of a long panel is avoided, the smooth and efficient construction is ensured, and the construction quality and the stand column precision are improved. The structure of the inner cylinder and the reinforcing steel bar net rack saves concrete materials and can ensure that the upright post has enough anti-overturning strength in the front and back directions. The concrete in the upright post and the foundation are poured into a whole, so that the structural integrity and the integral strength of the upright post are improved.

When the foundation pit is implemented, the diameter of the foundation pit is preferably a circle matched with the side length of the rectangular horizontal section of the upright column, and the sinking groove can be a circular groove with the diameter about twice that of the horizontal section circle of the foundation pit, so that the foundation pit can be conveniently obtained by directly adopting drilling equipment for excavation. Of course, the construction can also be a square foundation pit and a sinking groove.

In the above steps, the abutting state of the aligned outer edges of the four panels between each section of the upright column section is maintained by the following method, a connecting ear plate is inserted into an insertion groove between the end surfaces of every two adjacent panels, the outer end hanging part of a fastening connecting rod of the connecting ear plate is hung on a reinforcing steel bar net rack, and the upper half part of the connecting ear plate is exposed out of the upper end of the panel for the panel of the upper section of the upright column section to be installed (the exposed part of the connecting ear plate at the upper end of the uppermost section of the upright column section is cut off or flattened and then a top cover is arranged); and sleeving a tensioning rope sleeve at the middle part of each section of the upright post section, and removing the tensioning rope sleeve after concrete pouring is finished.
