Abstract

This utility model discloses a power cable trench support structure, including a power cable trench excavated in the soil layer, with two rows of symmetrically arranged retaining plates longitudinally inserted into the sidewalls of the power cable trench; a support component is inserted into the middle of the inner side of each retaining plate in the power cable trench, and the support component is in close contact with the retaining plate; a fixing component is connected to the upper part of the support component. The upper end of the wide plate is pulled and fixed externally by the cooperation of a circular chain, a first carabiner, a second carabiner, an anchor rod, and a pull ring, thereby improving the stability of the wide plate and the retaining plate, achieving the desired support effect for the power cable trench. Since the wide plate is externally fixed by a circular chain, there are no oblique or lateral components such as support plates that abut against the wide plate in the power cable trench, thus not occupying space in the power cable trench, and therefore not affecting the working space of the workers, nor causing injury to the workers.

Description

Technical Field

[0001] This utility model belongs to the field of cable laying protection technology, specifically, it relates to a power trench support structure. Background Technology

[0002] Power cable trenches are underground conduits used for laying and replacing power or telecommunications cables. They also serve as the enclosure structure for the cables being laid, and come in rectangular, circular, and arched shapes. During the construction of power cable trenches, a support structure is needed to ensure construction safety. Currently, there are two main methods for ensuring construction safety: wooden sheet pile support and steel sheet pile support. Wooden sheet pile support utilizes a combination of wooden sheets, piles, and bracing to support the walls of shallow foundation pits. Steel sheet piles are hot-rolled steel sections with interlocking or clamping jaws that are driven into the soil to form a continuous sheet pile wall, which is then combined with a support system to form a complete support system.

[0003] For example, a power trench support device disclosed in the prior art uses wooden baffles for support. However, the mutually abutting support plates installed on top often obstruct the construction work of workers, not only interfering with the workers' activity space but also potentially causing collision injuries to the workers, which has certain limitations. Utility Model Content

[0004] The purpose of this utility model is to provide a support structure for power cable trenches, which solves the technical problem that the support device in the prior art will occupy the activity space of the workers in the power cable trench, thus interfering with the workers' construction work and potentially causing injury to the workers.

[0005] The objective of this utility model can be achieved through the following technical solutions: A power cable trench support structure includes a power cable trench excavated in the soil, with two rows of symmetrically arranged retaining plates longitudinally inserted into the sidewalls of the trench. A support assembly is inserted into the trench at the center of the inner side of each retaining plate, and the support assembly is in close contact with the retaining plate. A fixing assembly is connected to the upper part of the support assembly, and the fixing assembly applies an outward pulling force to the upper part of the support assembly. The support assembly includes a wide plate with a through-hole (like a pig's snout). The fixing assembly includes a circular chain and a first carabiner and a second carabiner located at the beginning and end of the circular chain. The first carabiner can also be detachably equipped with two pull rings, which are respectively connected to the two holes of the "pig's snout".

[0006] Furthermore, the support assembly also includes two side plates integrally formed with the wide plate, wherein the side plates are located on both sides of the wide plate, and the wide plate and the side plates are of equal length, and the corners at the lower ends of the side plates away from the side plates are rounded.

[0007] Furthermore, a connecting plate is welded to the top of the side plate, which is positioned opposite to the wide plate and connects the two side plates; the pig's nostril also passes through the connecting plate.

[0008] Furthermore, the first carabiner and the second carabiner are detachably fastened to the two ends of the circular chain, respectively.

[0009] Furthermore, the fixing component also includes an anchor rod inserted obliquely into the soil layer, the lower end of which is conical and the upper end is a thin cylindrical structure.

[0010] Furthermore, the upper part of the anchor rod is welded with barbs.

[0011] The beneficial effects of this utility model are: 1. This utility model uses retaining plates to form two protective walls inserted into the sidewalls of the power cable trench, thereby preventing the soil layer from collapsing. Wide plates are then used to reinforce the retaining plates, improving the safety of cable laying. Subsequently, a circular chain, a first carabiner, a second carabiner, anchor bolts, and pull rings are used to pull and fix the upper end of the wide plate externally, thereby improving the stability of the wide plate and, consequently, the stability of the retaining plate, achieving the desired support effect for the power cable trench. Because the wide plate is externally fixed using a circular chain, there are no supporting plates or other oblique or lateral components that abut against the wide plate in the power cable trench, thus not occupying space within the trench and not affecting the workers' activity space or causing injury.

[0012] 2. Since the circular chain is equipped with a first carabiner and a second carabiner at both ends, this utility model can be used to fix the cable when the fixing conditions near the power cable trench are not good. It can be fixed by pulling it with a rope or by extending the length by using a linking method (i.e., first carabiner - circular chain - second carabiner - first carabiner - circular chain - second carabiner), which is flexible and convenient to use.

[0013] 3. Because the upper part of the wide plate and the side plate are reinforced with connecting plates, when the operator needs to insert the wide plate, the pull ring can be rotated to both sides and placed on the outer wall of the side plate. Then, the wide plate and the side plate can be inserted into the soil by hammering. This is convenient and will not be deformed by hammering. It is simple and practical. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 2 As shown, a power cable trench support structure includes a power cable trench 200 excavated in the soil layer 100 along the cable laying path, and the power cable trench 200 has a rectangular structure. The shape of the power cable trench 200 is not limited to rectangular; for example, it can also be a trapezoidal structure with both side walls sloping outwards.

[0017] Please refer to it again. Figure 1 As shown, two rows of symmetrically arranged retaining plates 10 are longitudinally inserted into the sidewall of the power cable trench 200. The retaining plates 10 in the same row form a protective wall that can prevent the soil layer 100 from collapsing. A support component 20 is inserted into the middle of the inner side of each retaining plate 10 inside the power cable trench 200. The support component 20 is in close contact with the retaining plate 10 and is used to limit the tilting of the retaining plate 10, thus protecting the soil layer 10. A fixing component 30 is connected to the upper part of the support component 20. The fixing component 30 applies an outward pulling force to the upper part of the support component 20.

[0018] Please refer to it again. Figure 2 As shown, the support assembly 20 includes an integrally formed wide plate 21 and two side plates 22, wherein the side plates 22 are located on both sides of the wide plate 21, and the wide plate 21 and the side plates 22 are of equal length. The corners of the lower ends of the side plates 22 away from the side plates 22 are rounded 25 to facilitate the workers to insert them into the soil layer 100 and to prevent the workers from being scratched. The support assembly 20 also includes a connecting plate 23 welded to the top of the side plates 22. The connecting plate 23 is arranged opposite to the wide plate 21 and connects the two side plates 22. The wide plate 21, the side plates 22 and the connecting plate 23 together form a square tube structure with a rectangular cross-section to increase the connection strength and rigidity at this point. Through holes 24 are opened on the connecting plate 23 and the wide plate 21.

[0019] Please refer to it again. Figure 2 As shown, the fixing component 30 includes a circular chain 31 and a first carabiner 32 and a second carabiner 33 located at the beginning and end of the circular chain 31. The first carabiner 32 and the second carabiner 33 are detachably fastened to the beginning and end of the circular chain 31, respectively. The first carabiner 32 is also detachably provided with two pull rings 36, which are respectively fastened to the two holes of the pig snout 24. The fixing component 30 also includes an anchor rod 34 that is obliquely inserted into the soil layer 100 at a 65° angle. The lower end of the anchor rod 34 is tapered for easy insertion, and the upper end is a thin cylindrical structure for easy hammering. The upper part of the anchor rod 34 is welded with a barb 35 to prevent the second carabiner 33 from falling off, and also to facilitate the application of an upward force to the anchor rod 34 when it is pulled out.

[0020] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below: The power trench support structure provided by this utility model consists of two protective walls inserted into the side wall of the power trench 200 by retaining plates 10, thereby preventing the collapse of the soil layer 100. The retaining plates 10 are reinforced by wide plates 21 to improve the safety of cable laying. Then, the upper end of the wide plate 21 is pulled and fixed externally by the cooperation of circular chain 31, first carabiner 32, second carabiner 33, anchor rod 34 and pull ring 36, thereby improving the stability of the wide plate 21 and the stability of the retaining plates 10, thus achieving the support effect of the power trench 200. Since the wide plate 21 is externally fixed by circular chain 31, there are no supporting plates or other components that abut against the wide plate 21 at an angle or laterally in the power trench 200, so it will not occupy the space in the power trench 200, and will not affect the activity space of the workers or cause them to be injured.

[0021] Since the circular chain 31 is equipped with a first carabiner 32 and a second carabiner 33 at both ends, when the fixing conditions near the power cable trench 200 are not good, it can be fixed by pulling it outward with a rope or by extending the length of the chain using a linking method (i.e., first carabiner 32 - circular chain 31 - second carabiner 33 - first carabiner 32 - circular chain 31 - second carabiner 33), making it flexible and convenient to use.

[0022] Since the upper ends of the wide plate 21 and the side plate 22 are reinforced with connecting plates, when the operator needs to insert the wide plate 21, the pull ring 36 can be rotated to the sides and placed on the outer wall of the side plate 22 respectively, and then the wide plate 21 and the side plate 22 can be inserted into the soil layer 100 by hammering. This is convenient and will not be deformed by hammering, which is simple and practical.

[0023] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
