[0034] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0035] Example 1:

[0036] See also Figure 1 and Figure 2 A buried cable protection trough box for use in narrow and curved sections of rural roads, comprising:

[0037] Trough rack 1;

[0038] A trough cover 2 movably connected to the upper end of the trough frame 1;

[0039] A first partition plate 3 and a second partition plate 4 are arranged in parallel inside the trough frame 1;

[0040] Among them, the interior of the trough frame 1 is divided into a first protection space 5, a second protection space 6 and a third protection space 7 by a first partition 3 and a second partition 4. An optical cable fixing 8 is provided in the first protection space 5, and a cable fixing 9 is provided in the second protection space 6 and the third protection space 7.

[0041] Specifically, the trough frame 1 comprises two side panels and a bottom panel, which are fixedly connected to the side panels. The bottom panel has three pre-embedded steel plates, to which optical cable holders 8 and electrical cable holders 9 are welded. The upper ends of the first and second partitions 3 and 4 are fixed to the trough cover 2. When the trough cover 2 is closed over the trough frame 1, the interior of the trough frame 1 is divided into a first protective space 5, a second protective space 6, and a third protective space 7 by the first and second partitions 3 and 4. An optical cable holder 8 is located within the first protective space 5, and two electrical cable holders 9 are located within the second and third protective spaces 6 and 7, respectively.
