[0025] As Figures 1-5As shown in the figure, a cable trench structure is provided with a quick - release cable support 5 system. The main body of the cable trench is composed of a prefabricated cable trench 1, and a water - collecting tank 2 is designed inside it for effective water collection and sewage discharge. An embedded prefabricated partition 3 is arranged on the side wall of the cable trench to divide the space inside the trench. Cable perforations 4 are opened on the partition, and special slots 7 are designed at the openings of the perforations for installing the quick - release cable support 5.

[0026] The core components of the quick - release cable support 5 include an L - shaped strip and a cable placement rack 55. At the opening of the cable perforation 4, two opposite L - shaped strips are installed, namely the first L - shaped strip 51 and the second L - shaped strip 52. Both the upper and lower ends of these two strips are provided with insertion blocks 53 that match the slots 7 to ensure the stable installation of the support. Alignment holes 54 are also opened on the end face of the L - shaped strip. Through these holes, the cable placement rack 55 can be inserted and fixed by fastening nuts 56. The cable placement rack 55 extends into the inner wall opening of the prefabricated cable trench 1 to form a stable cable support structure.

[0027] When cable maintenance or replacement is required, only the cable placement rack 55 needs to be removed, and at the same time, the embedded prefabricated partition 3 and the two L - shaped strips can be removed, simplifying the maintenance process. The entire prefabricated cable trench 1 and the embedded prefabricated partition 3 are pre - formed with concrete to ensure the strength and stability of the structure. Embodiment

[0028] This embodiment provides an improved cable trench structure, which adds a maintenance slide rail 64 system on the original basis. The main body of the cable trench is still composed of a prefabricated cable trench 1, and is equipped with a water - collecting tank 2 and an embedded prefabricated partition 3. The settings of the cable perforations 4 and the quick - release cable support 5 are the same as those in Embodiment 1, ensuring the stable support and quick - disassembly function of the cable.

[0035] Next, the first L-shaped bar 51 and the second L-shaped bar 52 are removed respectively. Since the upper and lower ends of the L-shaped bar are provided with inserting blocks 53, it is necessary to gently tap the inserting blocks 53 to disengage them from the slots 7.

[0036] As the L-shaped strip is disassembled, the cable through-holes 4 on the embedded prefabricated partition 3 will also be exposed, and at this time the entire quick-detachable cable bracket 5 is successfully disassembled.

[0037] When installing the quick-detachable inspection rail 6: After disassembling the cable support, prepare to install the quick-detachable inspection rail 6. First, determine the installation position and length of the inspection rail 64 to ensure that it can cover the area that needs to be inspected.

[0038] The L-shaped frame 61 is installed at the lower inner end of the removed first L-shaped strip 51 to ensure a stable installation.

[0039] A support block 63 is placed in the slide groove 62 of the L-shaped frame 61 and fixed with bolts. According to actual needs, the position of the support block 63 is adjusted to ensure that the inspection slide rail 64 and the cable placement frame 55 maintain an appropriate distance.

[0040] The inspection rail 64 is placed on the support block 63 to ensure that the rail is stable and firm. At this point, the quick-detachable inspection rail 6 has been preliminarily installed.

[0041] Finally, debug and inspect the track to ensure that the slide rail moves smoothly without obstruction and can meet the operational needs of maintenance personnel.
