Abstract
Description
Technical Field
[0001] This utility model relates to a cable trench, specifically a waterproof cable trench. Background Technology
[0002] Cable trenches are underground pipes used for laying and replacing power or telecommunications cables. They are also the enclosure structures for the cables being laid. They come in various pipe structures, such as rectangular, circular, and arched.
[0003] Because cables are laid inside cable trenches, it is necessary to prevent water accumulation inside the trenches. Therefore, a cover plate is usually laid on top of the cable trench. However, traditional ordinary cover plates have poor waterproofing effect, especially at the joint between two adjacent cover plates, which is prone to leakage problems. Utility Model Content
[0004] To address the technical problem of poor waterproofing between adjacent cover plates in existing technologies, this utility model provides a waterproof cable trench. By setting a connecting groove on the cover plate and installing a connecting plate covering the connecting groove, the sealing between adjacent cover plates is improved, giving it the advantage of better waterproofing.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0027] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0029] Example:
[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment discloses a waterproof cable trench, including a trench 10, a support frame 20, a cover plate 30, and a connecting plate 40. The trench 10 is excavated underground and its surroundings are filled with concrete to form a stable trough structure. The cross-section of the trench 10 is rectangular.
[0031] There are multiple support frames 20, and multiple support frames 20 are respectively provided on both side walls of the trench 10, and multiple support frames 20 are also provided along the extension direction of the trench 10. The support frames 20 are mainly used to support the cables in the trench 10.
[0032] Multiple closely adjacent cover plates 30 are provided on the top of the trench 10. The two sides of the cover plates 30 extend to the outside of the two sides of the trench 10. In addition, a drainage channel 11 is provided on the outside of the two sides of the trench 10. The two sides of the cover plates 30 are located above the drainage channels 11, so that water on the cover plates 30 can flow into the drainage channels 11.
[0033] After the two cover plates 30 are tightly abutted together, the two ends of the connecting plate 40 cover the ends of the two cover plates 30 that are close to each other. A connecting groove 32 is provided at the top of each end of the cover plate 30, and the two sides of the connecting plate 40 have connecting parts 41 that bend into the connecting groove 32. The two connecting parts 41 make the connecting plate 40 form a long strip structure with a U-shaped cross section.
[0034] In addition, the top surface of the cover plate 30 and the top surface of the connecting plate 40 are on the same plane. The top surfaces of both the cover plate 30 and the connecting plate 40 have a slope and are inclined towards the side of the cover plate 30, so that the water on the cover plate 30 and the water on the connecting plate 40 can flow into the drainage ditch 11.
[0035] In practical applications, the extension direction of the groove 10 is curved, and its direction is adapted to the actual needs. Therefore, the shape of the cover plate 30 is not necessarily rectangular, but can be other irregular shapes. It is only necessary to ensure that a connecting groove 32 is provided at the end where the two cover plates 30 abut each other, so as to facilitate the installation of the connecting plate 40.
[0036] During operation, when rainwater or other water stains overflow from the top of the cover plate 30, the water cannot seep into the trench 10 at the contact point between the two adjacent cover plates 30 due to the obstruction of the connecting plate 40. Instead, the water can only flow into the drainage ditch 11 from both sides of the cover plate 30.
[0037] By providing a connecting groove 32 on the cover plate 30 and installing a connecting plate 40 covering the connecting groove 32, the sealing between two adjacent cover plates 30 is improved, giving the cable trench the advantage of better waterproofing.
[0038] In one specific embodiment:
[0039] A water trough 12 is provided on the top of the outer wall of the trench 10. The water trough 12 is connected to the top of the drainage ditch 11. The top of the drainage ditch 11 is a closed structure. The water trough 12 is used to achieve air pressure balance with the outside. By setting the water trough 12, foreign objects can be prevented from entering the drainage ditch 11 and causing blockage.
[0040] In addition, a guide portion 31 is provided on each side of the cover plate 30. The two guide portions 31 are bent towards the bottom of the cover plate 30 and can be embedded in the water tank 12 respectively. This makes the contact surface between the cover plate 30 and the groove 10 higher than the side of the cover plate 30, thereby preventing water from seeping into the groove 10 from the contact surface between the cover plate 30 and the groove 10. At the same time, after the guide portion 31 at the end of the cover plate 30 is embedded in the water tank 12, the internal size of the water tank 12 is reduced, which can prevent foreign objects from entering the water tank 12.
[0041] In another specific embodiment:
[0042] The top surfaces of both the cover plate 30 and the connecting plate 40 are higher in the middle than on both sides, so that the water on the cover plate 30 and the connecting plate 40 can flow into the drainage channels 11 on both sides of the trench 10, thus preventing a single drainage channel 11 from being filled.
[0043] In another specific embodiment:
[0044] The bottom of the cover plate 30 is provided with a weight-reducing hollow area. By setting the weight-reducing hollow area, the weight of the cover plate 30 is reduced, making it easier to handle, install and disassemble.
[0045] In another specific embodiment:
[0046] The portion of the connecting plate 40 that can be embedded in the connecting groove 32 is provided with a high-pressure zone 42. The high-pressure zone 42 is a hollow structure and exists inside the connecting portion 41, while also being located within the connecting groove 32 of the cover plate 30. By providing the high-pressure zone 42, the effect of air pressure can be used to prevent water from seeping from the connecting groove 32 into the trench 10.
[0047] In another specific embodiment:
[0048] The slope of the top surfaces of the connecting plate 40 and the cover plate 30 is less than or equal to 1°. By setting a small slope, the water flow can be guided and the top of the trench 10 can be prevented from protruding too high.
[0049] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
