[0026] Cable trench is a basic facility in the construction of power projects such as power plants and substations. Currently, the commonly used cable trenches are divided into two categories: cast-in-place construction and prefabricated cable trenches. Cast-in-place cable trenches have problems such as long on-site construction period, great impact on the surrounding environment, great seasonal influence, and difficulty in installing equipment brackets. Therefore, in order to make power construction develop in the direction of resource conservation, environmental friendliness and industrialization, it has become a trend in the development of the industry to replace cast-in-place cable trenches with prefabricated cable trenches. Prefabricated cable trenches can better realize factory production and standardized construction; however, most common prefabricated cable trenches are currently formed in one piece, which makes the interface size and weight of the components large, resulting in the corresponding prefabricated cable trench The installation and construction is not convenient. Therefore, the utility model proposes a cable trench assembly.

[0027] See also Figure 1 , 23. In one embodiment of the utility model, the cable trench assembly includes a bottom plate 100 and at least two side plates 200; the bottom plate 100 and the side plates 200 can be made of concrete, preferably, high-strength concrete can be used to improve strength and reduce weight. The bottom plate 100 is used to form the bottom of the cable trench, and the side plates 200 are used to form the side walls of the cable trench, which is equivalent to further disassembling and designing the components of the common assembled cable trench, so that the size and weight of the components of the assembled cable trench are correspondingly reduced, so that the installation construction is more convenient. A first protrusion 210 is provided on the side of the first end of the side panel 200 facing the inside of the cable trench; the bottom panel 100 is overlapped on the first protrusion 210, and a first overlapping surface 211 is provided on the side of the first protrusion 210 facing the bottom panel 100, and a second overlapping surface 110 is provided at the bottom of the bottom panel 100; one of the first overlapping surface 211 and the second overlapping surface 110 is provided with an insert 220, and the other of the first overlapping surface 211 and the second overlapping surface 110 is provided with a slot 120, and the insert 220 is inserted and matched with the slot 120; with such an arrangement, the two side panels 200 are installed to a suitable position during construction, and the bottom panel 100 is overlapped to the first protrusion 210 of the side panel 200 through the insert 220 and the slot 120 structure, so that the laying of the cable trench can be completed, which further improves the convenience of installation and construction. The connection method between the plug body 220 and the slot 120 is also conducive to limiting the movement of the bottom plate 100 in the width direction of the cable trench to improve the stability of the cable trench. In addition, since the bottom plate 100 is mounted on the first protrusion 210, there is a certain distance between the bottom of the bottom plate 100 and the installation surface. Therefore, the bottom wall of the bottom plate 100 and the side wall of the first protrusion 210 facing the inside of the cable trench together form a drainage ditch. When the cable trench assembly is installed underground or outdoors, there may be groundwater or other accumulated water outside the cable trench. The drainage ditch can be used to guide and discharge the accumulated water to reduce the risk of the accumulated water seeping into the cable trench.

[0028] Further, in some embodiments, see Figure 1 , 2 , the first lap joint surface 211 is provided with a plug 220, and the second lap joint surface 110 is provided with a slot 120. With such an arrangement, the risk of damage to the plug 220 can be reduced. Specifically, the plug 220 is arranged on the first lap joint surface 211, which is equivalent to being arranged on the inner side of the "L"-shaped structure of the side panel 200, so as to reduce bumps and squeezing during movement or installation, thereby reducing the risk of damage and playing a certain protective role for the plug 220. In some embodiments, the first lap joint surface 211 is provided with a plurality of plugs 220, and the second lap joint surface 110 is provided with a plurality of slots 120, and the number of slots 120 is greater than or equal to the number of plugs 220; the length directions of the slots 120 and the plug 220 are parallel to the length direction of the cable trench. By providing a plurality of plugs 220 and slots 120, the connection strength between the bottom plate 100 and the side panel 200 can be improved.

[0029] In some embodiments, see Figure 1 A second protrusion 230 is provided on the side of the first end of the side plate 200 facing away from the inside of the cable trench. The second protrusion 230 can be used to form a support outside the cable trench to reduce the risk of overturning.

[0030] In some embodiments, see Figure 1 A wall column 240 is provided on the side of the side plate 200 facing away from the inside of the cable trench, and the wall column 240 extends along the height direction of the cable trench. The arrangement of the wall column 240 can change the force-bearing mode of the side plate 200, and disperse the force perpendicular to the side plate 200 to the direction parallel to the side plate 200, so as to reduce the bending moment of the side plate 200, thereby improving the stability of the cable trench. Furthermore, a plurality of wall columns 240 can be provided, and the plurality of wall columns 240 are arranged at intervals on the side of the side plate 200 facing away from the inside of the cable trench, so as to further improve the stability.

[0031] In some embodiments, see Figure 1 At least two recessed portions 250 are formed inwardly on the side of the side plate 200 facing away from the inside of the cable trench, and the recessed portions 250 are distributed along the length direction of the cable trench, and the protrusions between two adjacent recessed portions 250 form the wall column 240. In this way, the wall column 240 structure is formed by the recesses, which is conducive to reducing weight and further improving the convenience of installation.

[0032] In some embodiments, see Figure 1 , 4 The cable trench assembly further includes a cover plate 300; a notch is provided at the second end of the side plate 200, and the second end of the side plate 200 is arranged opposite to the first end of the side plate 200; the notch forms a receiving groove 260 for receiving the cover plate 300, so that the cover plate 300 overlaps the bottom of the receiving groove 260. With such an arrangement, the cover plate 300 and the side plate 200 can be quickly spliced ​​during installation. Specifically, during installation, the cover plate 300 overlaps the receiving groove 260, so that the bottom wall of the receiving groove 260 receives the bottom of the cover plate 300, and the side wall of the receiving groove 260 abuts against the side wall of the cover plate 300. Among them, the side wall of the receiving groove 260 plays a role of limiting and guiding.

[0033] In some embodiments, see Figure 1 , 4A splicing gap 400 is provided between the side of the bottom plate 100 and the side wall of the side plate 200; a drainage groove 212 is provided on the first protruding portion, and the drainage groove 212 is connected to the splicing gap 400. The drainage groove 212 is used to collect and drain the accumulated water in the cable trench. Preferably, the drainage groove 212 is provided at the starting point of the first end of the first protruding portion protruding from the side plate 200; in this way, the drainage groove 212 is equivalent to being provided at the position where the side wall of the side plate 200 and the first protruding portion are connected; and there may be a stress concentration phenomenon at this position, and the drainage groove 212 provided here helps to reduce the stress concentration and reduce the risk of cracking at the connection.

[0034] In some embodiments, the bottom plate 100 may be integrally formed; the side plate 200 may also be integrally formed; and the cover plate 300 may also be integrally formed.

[0035] In addition, it can be understood that the cable trench assembly proposed by the utility model is used for assembled cable trenches; the cable trench assembly can be prefabricated and then installed. When multiple cable trench assemblies are installed according to the preset plan, a cable trench can be formed.

[0036] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
