This construction is particularly suitable for the current development of high-speed railway construction. With the rapid development of high-speed railways, the safety of new lines and safety during the construction process are particularly important. The installation of pier hanging fences provides convenience for construction and maintenance work, making the inspection, maintenance and replacement of pier bearings more efficient and safe. This facility can not only protect construction workers from accidental injuries, but also help improve construction efficiency and shorten the construction period, thereby ensuring the safety and engineering quality of new high-speed railway lines.

[0015] The working principle and beneficial effects of the utility model are:
[0016] In the utility model, the guardrail is folded to reduce the volume of the device, so that the fence can be folded into a smaller size during transportation, saving transportation space, and more fences can be loaded in the same transportation container or vehicle, thereby improving transportation efficiency.

After the engaging column 5 is fully extended, a section of the volume will be located in the slot 10, so that the fixing block 2 and the slot 10 are connected at the same time through the engaging column 5, so as to limit the guardrail 9. A second slide groove 6 is provided on the left inner end of the first limiting column 4, and a second limiting column 8 is fixedly connected to the left inner wall of the first slide groove 3. The second limiting column 8 is fixed by the first slide groove 3, and a first spring 7 is provided on the outside of the second limiting column 8, and the first spring 7 is limited by the second limiting column 8.
[0027] In this embodiment, the engaging column 5 is engaged with the fixing block 2 , and the fixing block 2 is engaged by the engaging column 5 , thereby limiting the position of the guardrail 9 .
[0028] In this embodiment, the second sliding groove 6 is slidably connected to the second limiting column 8 . Example 2
[0029] On the basis of Example 1, a preferred embodiment of a hanging fence for safety protection of high-speed railway piers provided by the utility model is as follows: Figures 1 to 5 As shown: the inner wall of the bottom plate 1 is fixedly connected with evenly distributed fixed baffles 11, and the fixed baffles 11 are fixed by the bottom plate 1, and the right inner end of the fixed baffle 11 is fixedly connected with evenly distributed buffer plates 12, and the buffer plates 12 are fixed by the fixed baffles 11.
[0030] In this embodiment, the right side of the buffer plate 12 is fixedly connected to a limiting frame 14, and the limiting frame 14 is fixed by the buffer plate 12. The right side of the limiting frame 14 is fixedly connected to a protective cover 13, and the fixed baffle 11 and the protective cover 13 are connected by the buffer plate 12.
[0031] In this embodiment, the right outer end of the fixed baffle 11 is fixedly connected with evenly distributed transmission columns 15, and the transmission columns 15 are fixed by the fixed baffle 11.
