Description

Technical Field

[0001] This utility model relates to the field of power engineering construction technology, and in particular to a new type of cable trench cover. Background Technology

[0002] In power engineering construction, whether it is the construction of substations or lines, there are a large number of cable trenches. The cables are laid out in the cable trenches, and the cable trenches need to be covered to protect the cables.

[0003] In existing technologies, cable trench covers typically use galvanized edged covers, where hot-dip galvanized angle iron is used to edge the main body of the concrete cover. The main purpose of this edged design is to significantly enhance the strength and impact resistance of the cover edges, preventing damage during transportation, installation, and maintenance. It also improves the fit between the cover and the trench, reducing wobbling. However, the quality of the galvanized layer in galvanized edged covers varies. Insufficient galvanized layer thickness and subsequent processing that damages the original galvanized layer structure result in poor corrosion resistance, potentially causing rust within a few months of use, thus affecting the cover's lifespan and performance. Even with hot-dip galvanized covers, if the galvanized layer is damaged during transportation, installation, or use, the sheet is easily exposed to air, leading to rust. This requires careful maintenance and timely repair of damaged galvanized layers, increasing operating costs and maintenance workload.

[0004] In order to improve the strength and impact resistance of the cover edge, the existing cable trench cover adopts a galvanized edge structure. However, the galvanized layer is prone to failure during use, which leads to rust and makes subsequent maintenance difficult. Utility Model Content

[0005] This utility model provides a novel cable trench cover that solves the problem of difficult later maintenance in existing technologies. The technical solution is as follows: A novel cable trench cover includes: multiple cover bodies arranged side by side, each cover body being a square concrete component, and a reinforcing rib provided on the bottom edge of each cover body. The reinforcing rib includes a first reinforcing rib and a second reinforcing rib, wherein the first reinforcing rib is arranged along the length direction of the cover body and the second reinforcing rib is arranged along the width direction of the cover body.

[0006] Optionally, the cover includes a first cover and a second cover, which are arranged alternately. The first cover has a first lug protruding laterally on both sides, and a drainage groove arranged along the length of the first cover is provided on the top of the first lug.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

Figures 1 to 9The present invention relates to a novel cable trench cover, comprising: multiple cover bodies 1 arranged side by side, each cover body 1 being a square concrete component, and a reinforcing rib 2 provided at the bottom edge of the cover body 1, the reinforcing rib 2 including a first reinforcing rib 21 and a second reinforcing rib 22, the first reinforcing rib 21 being arranged along the length direction of the cover body, and the second reinforcing rib 22 being arranged along the width direction of the cover body 1.

[0021] Exemplarily, in this embodiment of the invention, operating holes are provided at both ends of the cover 1, facilitating transportation and installation of the cover 1 during transport. The cover 1 adopts a beam-plate design, with first reinforcing ribs 21 and second reinforcing ribs 22 at the main stress-bearing positions and plate surfaces at secondary positions. Due to the high strength and toughness of its material, a smaller cross-sectional size can be used for the same structural strength, thereby reducing the volume and weight of the components, providing greater freedom and flexibility for on-site construction, and reducing manufacturing costs. This embodiment uses self-compacting concrete, eliminating the need for the original vibration method, solving the problem of insufficient compaction caused by manual vibration, and ensuring production quality. This embodiment uses higher-strength concrete to replace the original ordinary concrete, increasing the fiber volume content in the concrete, enabling it to withstand greater deformation without damage when subjected to impact or vibration, completely replacing the original galvanized edge-sealed angle iron, solving problems such as later corrosion and peeling, and reducing later maintenance costs.

[0022] Taking a 1700*500*50mm cover plate as an example, in the existing technology for construction and installation within substations, the cover plate is a galvanized edged cover plate. The cover plate is made of C40 strength concrete, with L50*50*5mm angle iron edging on all four sides, and internal steel bars of 8mm and 6mm diameter. The specific materials used for the cover plate are as follows: The weight of a single cover plate is: G1 = 1.7 * 0.5 * 0.05 * 2400 = 102 kg.

[0023] Weight of a single galvanized angle iron cover plate: G2 = (1.7 * 2 + 0.5 * 2) * 3.770 = 16.588 kg.

[0024] The weight of the steel reinforcement used in a single cover plate is: G3 = 1.7 * 4 * 0.395 + 0.5 * 9 * 0.395 = 4.46 kg.

[0025] The construction of the cover plate requires several processes, including cutting and welding angle iron; sending the angle iron to the processing plant for galvanizing; welding steel mesh to the angle iron frame after returning to the factory; installing the angle iron frame onto the casting mold; pouring concrete; demolding and packaging; and finally, warehousing.

[0026] In this embodiment, high-strength concrete is used instead of galvanized edge-sealed angle iron cover plates. The dimensions are also 1700*500*50mm. To achieve the same or even higher strength as the galvanized edge-sealed cover plates, cover body 1 adopts a beam-slab structure. The beams are reinforced with steel bars for tensile strength, while the slab relies on the inherent fibers of the concrete material for tensile strength. The beams have a 40*50mm cross-section (only needing to meet the thickness of the steel reinforcement protective layer). Because cover body 1 needs good hydrophobicity, the top surface of cover body 1 is designed with a slightly curved cross-section, with a thickness of 50mm in the middle and 45mm on the two short sides. Therefore, the slab thickness is designed to be 15-20mm. Thus, the practical materials for cover body 1 are as follows: The weight of a single cover piece 1 is: G1 = 62 kg.

[0027] The weight of the steel reinforcement used in a single cover piece 1 is G3 = 4.1 kg.

[0028] The construction of cover body 1 only requires welding the steel mesh; installing the formwork and pouring the concrete; demolding, packaging, and warehousing to complete production. Compared to the galvanized angle iron edging in existing technologies, this cover plate structure adopts a beam-slab structure, saving approximately 40% of concrete, resulting in lighter weight and lower labor intensity during on-site construction; eliminating the use of galvanized angle iron edging saves 100% on profile usage and reduces production processes, making production more convenient and lowering production costs; using higher-strength concrete, relying on the inherent properties of concrete, under the same load requirements, the internal reinforcement of cover body 1 is reduced by approximately 8%; in summary, it is more economical.

[0029] This utility model provides a novel cable trench cover. By setting reinforcing ribs 2 at the bottom edge of the cover 1, the strength and impact resistance of the edge of the cover 1 can be improved. The cover 1 is made of concrete casting, which replaces the structure of galvanized edge-wrapped angle iron in the prior art, solves the problems of later corrosion and peeling, and reduces the frequency of later maintenance. This can effectively solve the problem of difficult later maintenance in the prior art.

[0030] Optionally, the cover 1 includes a first cover 11 and a second cover 12, the first cover 11 and the second cover 12 are arranged alternately, the first cover 11 has a first ear 111 protruding outward laterally on both sides, the top of the first ear 111 has a drainage groove 112 arranged along the length direction of the first cover 11, and the second cover 12 has a second ear 121 protruding outward laterally on both sides, the second ear 121 overlaps the first ear 111.

[0031] Exemplary, in embodiments of this utility model, such as Figure 3As shown, the overlapping fit of the first lug 111 and the second lug 121 limits the fit between the first cover 11 and the second cover, making the overall cover plate more stable after the fit is completed. When rainwater or other liquids are present on the upper surface of the cover 1, they will first flow into the edge drainage groove 112 through the edge of the cover 1, and then flow along the drainage groove 112 to both ends of the cover 1 for discharge. In places with higher requirements for wind and sand sealing, sealing strips can also be installed in the groove. The weight of the cover 1 will flatten the sealing strip, achieving a complete seal. Furthermore, with the overlapping method in this embodiment, when it is necessary to maintain the cables in the cable trench, only the cover 1 of the target area needs to be removed. At most, only one first cover 11 and one second cover 12 need to be removed to maintain the target area. Compared with the traditional end-to-end overlapping method, which requires the removal of all cover plates to maintain the target area, the overlapping method in this embodiment is more convenient to operate during maintenance.

[0032] Optionally, a support bar 113 is provided on the side of the drainage groove 112 away from the first cover 11, and the support bar 113 is arranged along the length of the first cover 11.

[0033] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, by setting the support bar 113, the space of the drainage groove 112 can be expanded, which can prevent the drainage groove 112 from failing due to the first cover 11 and the second cover 12 being too tightly closed. By setting this structure, liquid can be more easily discharged to the outside of the cover plate through the drainage groove 112, thereby improving the drainage effect of the cover plate.

[0034] Optionally, the support bar 113 is provided with reinforcing bars along its length.

[0035] For example, in this embodiment of the present invention, the support bar 113 serves as the load-bearing part where the first cover 11 and the second cover 12 overlap. By setting steel bars inside it, the structural strength of the support bar 113 can be improved, thereby providing a more stable support force for the second cover 12.

[0036] Optionally, the second lug 121 is provided with a steel bar parallel to the first reinforcing rib.

[0037] For example, in this embodiment of the present invention, the second lug 121 serves as the load-bearing part where the first cover 11 and the second cover 12 overlap. By setting steel bars inside it, the structural strength of the second lug 121 can be improved, thereby improving the structural strength of the second cover 12 and preventing the second cover 12 from being damaged due to excessive external pressure.

[0038] Optionally, the first reinforcing rib 21 of the second cover 12 is provided with an auxiliary reinforcing rib 122 on the side near the first cover 11. The auxiliary reinforcing rib 122 is positioned toward the support bar 113, and the support bar 113 is provided with an installation groove 114 that matches the auxiliary reinforcing rib 122.

[0039] Exemplary, in embodiments of this utility model, such as Figure 6 , Figure 7 and Figure 9 As shown, the auxiliary reinforcing rib 122 can be a steel bar. By lapping the auxiliary reinforcing rib 122 in the mounting groove 114, it can overlap with the steel bars inside the support strip 113. Through the overlap between the steel bars, the structural strength of the first cover 11 and the second cover 12 can be improved, preventing damage to the mating parts between the first cover 11 and the second cover 12 due to excessive external pressure. Furthermore, the cooperation between the auxiliary reinforcing rib 122 and the mounting groove 114 can restrict the movement of the first cover 11 and the second cover 12 along the length direction, preventing misalignment and further improving the stability of the mating of the first cover 11 and the second cover 12.

[0040] Optionally, multiple auxiliary reinforcing ribs 122 are arranged at intervals along the direction of the first reinforcing rib 21, and multiple mounting grooves 114 are arranged at intervals along the direction of the first reinforcing rib 21.

[0041] Exemplary, in embodiments of this utility model, such as Figure 7 and Figure 9 As shown, by setting multiple pairs of matching auxiliary reinforcing ribs 122 and mounting grooves 114, the fit stability of the first cover 11 and the second cover 12 is further improved.

[0042] Optionally, the height of the middle part of the bottom of the drainage trough 112 is higher than the height of the two ends.

[0043] Exemplary, in embodiments of this utility model, such as Figure 6 As shown, the bottom of the drainage trough 112 can be set in the form of two slopes. The bottom of the drainage trough 112 in the middle is higher and the bottom of the drainage trough 112 at the end is lower. By setting this structure, when there is liquid in the drainage trough 112, it will flow to both ends of the first cover 11, thereby further improving the drainage performance of the cover plate.

[0044] Optionally, the top profile of the cover 1 along its length is convex arc-shaped.

[0045] Exemplary, in embodiments of this utility model, such as Figure 5As shown, the top of the cover 1 is designed with a slight arc. When there is rain or oil on the upper part of the cover 1, the arc design allows the liquid to be discharged to both ends of the cover 1, avoiding liquid accumulation. It can also reduce the amount of liquid flowing into the drainage groove 112, keeping the cover surface clean while reducing the drainage pressure of the drainage groove 112, and further improving the drainage performance of the cover.

[0046] Optionally, the top of the cover 1 is provided with anti-slip texture 13.

[0047] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, by providing anti-slip texture 13 on the top of the cover 1, the anti-slip performance of the cover 1 can be improved, preventing people from slipping when walking on it, thus improving the safety performance of the cover 1. At the same time, the anti-slip texture 13 can be customized into different patterns according to customer needs, thereby improving the economic performance of this cover.
