Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 2, the light high-strength steel rectangular pipe railway protective fence for steep slope sections of the utility model comprises a plurality of ground openings arranged on the ground along the steep slope, wherein a vertical upright post 3 is fixed in each ground opening by pouring first concrete 1; a square fence is fixed between two adjacent upright posts 3, and a second concrete 2 embedded in the ground is filled and poured between the lower part of each fence and the ground;

the cell width of the fence (i.e., the width of a single fence) decreases as the ground slope increases.

The unit width of the fence in the area of the ground with the gradient less than 6 degrees is set to be 3.0m, and the unit widths of the fence with other gradients can adopt smaller width values as required.

The bottom end of the upright post 3 is fixed with a hook bolt 10, and the hook bolt 10 is embedded in advance and poured with first concrete 1 embedded in the ground opening.

The bottom end of the upright post 3 is fixed on a horizontal angle steel base 9 through a fastener, and a hook bolt 10 is fixed at the bottom end of the angle steel base 9.

The fence comprises a horizontal upper fence 6 and a horizontal lower fence 7, and a plurality of vertical cores 8 vertically fixed between the upper fence 6 and the lower fence 7.

The upright post 3 is connected with the core 8 close to the upright post 3 through a connecting plate 4.

Short vertical columns 5 are welded at the top ends of the vertical columns 3, and a barbed wire rolling cage (not drawn in the drawing) is welded between every two adjacent short vertical columns 5.

Some dimensional information may be taken as follows: the height of a fence formed by splicing the steel rectangular pipes is 2.2m, and a 0.5m barbed wire rolling cage is additionally arranged at the top of the fence. The gradient of the ground longitudinal slope is less than 6 degrees, and the width of a single fence can be set to be 3.0m; when the ground longitudinal slope is greater than or equal to 6 degrees, the unit length of the fence can be reasonably selected according to the longitudinal slope, but the general principle is that the larger the slope is, the smaller the width of the fence is.
