Description

Technical Field

[0001] This utility model relates to the field of pipe trench technology, and in particular to prefabricated U-shaped integrated power pipe trench. Background Technology

[0002] Integrated power utility trenches are widely used in the construction of underground pipelines in urban core areas, new urban areas, and industrial parks. Under urban roads, they can centrally accommodate high-voltage cables, low-voltage cables, and supporting facilities, avoiding the need for separate excavation and laying of power lines and water supply, drainage, and communication lines, thus reducing repeated road construction. In industrial parks, they can meet the dense power demand of enterprises, providing a unified laying channel for multiple power lines, facilitating centralized management in the later stages. They are especially suitable for areas with high requirements for underground space utilization and pipeline safety, and are an important infrastructure to ensure the stability of urban power supply.

[0003] However, it has significant drawbacks: the channel space is fixed, making it difficult to expand when adding new pipelines later; once a problem occurs, it can easily affect the normal operation of all pipelines, and the internal maintenance environment is complex, with high maintenance difficulty and safety risks; the dimensions of prefabricated components are fixed, making it difficult to adapt to pipeline routes in complex terrains; and when a part is damaged, the entire component needs to be replaced, resulting in high maintenance costs.

[0004] In the prior art, for example, there is a reusable light steel integrated pipe trench with publication number CN218508483U, which relates to the field of pipe trench technology. It includes multiple pipe trench segments spliced ​​together, with each segment having a U-shaped longitudinal section. One end of each segment has a female connector, and the other end has a male connector. The female and male connectors are fitted together. The female connector includes U-shaped members positioned opposite each other on both sides of the pipe trench segment, with their openings facing each other. The male connector includes L-shaped members positioned opposite each other, with their openings facing away from each other. The vertical axis of the L-shaped member is inserted into and fitted with the opening of the U-shaped member. There is space between the bottom of the L-shaped member and the bottom of the pipe trench segment for the bottom of the U-shaped member to be inserted. Both the U-shaped and L-shaped members are integrally formed with the pipe trench. This utility model's integrated pipe trench features simple and quick assembly, convenient operation, durability, high functionality, and high reusability. However, this design also has some drawbacks. It does not have a pipeline fixing device and lacks drainage equipment, which can easily lead to water accumulation and soaking of the pipeline. It is difficult to simultaneously take into account the pipeline's compatibility, drainage function and ease of maintenance.

[0005] Therefore, this application provides a prefabricated U-shaped integrated power trench to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology by proposing a prefabricated U-shaped integrated power trench, which has a simple structure and is easy to assemble.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A prefabricated U-shaped integrated power trench includes trench segments. Several support columns are fixedly installed on both sides of the inner wall of each trench segment. Three fixing screws are threaded on one side of each support column. A fixing bolt is threaded to one end of each fixing screw. A first snap-fit ​​block is fixedly installed at one end of each trench segment, and a second snap-fit ​​block is fixedly installed at the other end of each trench segment. A sealing gasket is fixedly installed on the snap-fit ​​contact surface between the second snap-fit ​​block and the first snap-fit ​​block.

[0008] Furthermore, a water collection pit is fixedly installed at the lower end of the trench segment, and water pipes are fixedly installed at the lower ends of both sides of the water collection pit.

[0009] Furthermore, a cover plate is snapped onto the upper end of the trench segment, and multiple movable blocks are fixedly installed on the upper end of the cover plate, with handles rotatably arranged between the movable blocks.

[0010] Furthermore, limit plates are snapped onto the upper and lower ends of several of the support columns.

[0011] Furthermore, several of the support columns have sliding grooves on both sides, and two of the sliding grooves have support plates that are slidably arranged inside them. A support frame is fixedly arranged at the lower end of each support plate.

[0012] Furthermore, tightening screws are threaded onto one end of both sides of the support plate.

[0013] Furthermore, a pipe clamp is fixedly installed at the upper end of the support plate, and an adjuster is installed at the upper end of the pipe clamp.

[0014] This utility model has the following beneficial effects: 1. The prefabricated U-shaped integrated power conduit trench proposed in this utility model features a support plate that can move up and down within the sliding groove of the support column. Its position is fixed by tightening screws, and with the help of adjustable clamps, it can flexibly adapt to power conduits of different diameters, solving the problem that traditional fixed structures can only accommodate a single conduit diameter and meeting various pipeline laying needs. Furthermore, the support column and support plate are connected by tightening screws, allowing for disassembly without damaging the overall structure; simply unscrewing the screws is sufficient for disassembly, significantly simplifying the maintenance process, reducing maintenance time and costs, and improving the flexibility and practicality of the conduit trench. 2. The prefabricated U-shaped integrated power cable trench proposed in this utility model connects the trench segments from top to bottom using snap-fit ​​blocks. This allows for rapid length expansion without complex splicing tools, adapting to the size requirements of different laying scenarios and significantly improving installation efficiency. The sealing gaskets at the connection surfaces effectively block groundwater and impurities, preventing moisture inside the trench and ensuring the safety of the power lines. Simultaneously, the sump at the bottom of each segment collects accumulated water, forming a drainage system with the water pipes between the sump pipes, preventing water from soaking the pipelines and reducing maintenance risks.

[0017] 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.

[0018] Reference Figure 2 , Figure 3 , Figure 4 One embodiment provided by this utility model: The prefabricated U-shaped integrated power trench includes a trench segment 4. Several support columns 9 are fixedly installed on both sides of the inner wall of the trench segment 4. Three fixing screws 7 are threaded on one side of the support column 9. A fixing bolt 8 is threaded to one end of the fixing screw 7. A first snap-fit ​​block 18 is fixedly installed at one end of the trench segment 4. A second snap-fit ​​block 19 is fixedly installed at the other end of the trench segment 4. A sealing gasket 17 is fixedly installed on the snap-fit ​​contact surface between the second snap-fit ​​block 19 and the first snap-fit ​​block 18.

[0019] Specifically, trench segment 4 is precast using C30 reinforced concrete and has a U-shaped structure to provide laying space for power lines; support columns 9 are vertically fixed on both sides of the inner wall of trench segment 4 to install support plates 13 and provide a support foundation for the pipeline; fixing screws 7 and fixing bolts 8 cooperate to firmly fix the support columns 9 to the inner wall of trench segment 4 to prevent the support columns 9 from shifting under force; the first clamping block 18 and the second clamping block 19 are located at both ends of trench segment 4, which can realize the rapid splicing of two adjacent trench segments 4; the sealing gasket 17 is pasted on the first clamping block 18 and fits tightly with the second clamping block 19, which can prevent impurities from entering the trench, prevent the pipeline from getting damp or corroded by impurities, and ensure the safety of the power pipeline.

[0020] Reference Figure 2 A water collection pit 5 is fixedly installed at the lower end of the trench segment 4, and water pipes 6 are fixedly installed at the lower ends of both sides of the water collection pit 5.

[0021] Specifically, the inner wall of the water collection pit 5 is treated with epoxy resin for corrosion protection and is used to collect water accumulated in the pipe trench to prevent water from soaking the pipeline. A stainless steel removable filter basket is installed at the bottom of the water collection pit 5 to intercept impurities. The filter basket is fixed by buckles and can be directly removed for cleaning. The water pipe 6 connects the water collection pits 5 of two adjacent pipe trench sections 4, so that all the water collection pits 5 form a continuous drainage channel. The accumulated water can be discharged to the outside of the pipe trench through the water pipe to prevent water accumulation in the pipe trench and reduce the risk of corrosion of the pipeline 6.

[0022] Reference Figure 1 The upper end of the trench segment 4 is fitted with a cover plate 3, and multiple movable blocks 2 are fixedly installed on the upper end of the cover plate 3. A handle 1 is provided between the movable blocks 2 for rotation.

[0023] Specifically, the cover plate 3 is made of fiberglass reinforced plastic and is snapped onto the upper end of the trench segment 4. It can cover the trench opening and prevent rainwater and garbage from falling into the trench. The movable block 2 provides an installation fulcrum for the handle 1. The handle 1 is made of stainless steel and can rotate around the movable block 2. The cover plate 3 can be easily removed by lifting the handle 1 upwards, which facilitates the later opening of the trench for pipeline maintenance and makes the operation more convenient.

[0024] Reference Figure 3 Several support columns 9 are fitted with limit plates 10 at their upper and lower ends.

[0025] Specifically, the limiting plate 10 is snapped onto the upper and lower ends of the support column 9 to limit the sliding range of the support plate 13, prevent the support plate 13 from coming out of the groove 16 of the support column 9 when it moves up and down, avoid excessive downward movement of the support plate 13 under excessive force, ensure the stability of the pipeline support, and at the same time, the snapping allows the support plate 13 to be disassembled at any time, which is convenient for the replacement and maintenance of the support plate 13.

[0026] Reference Figure 3 , Figure 4Several support columns 9 have sliding grooves 16 on both sides, and support plates 13 are slidably arranged inside the two sliding grooves 16. Support frames 14 are fixedly arranged at the lower end of the support plates 13.

[0027] Specifically, the chute 16 is a long, narrow groove on both sides of the support column 9, providing a track for the support plate 13 to slide up and down; the support plate 13 is made of Q235 steel and is horizontally set in the chute 16. By sliding the support plate 13 up and down, the laying height of the pipeline can be adjusted to adapt to the installation requirements of pipelines of different thicknesses; the support frame 14 is welded to the lower end of the support plate 13 and has a triangular structure, which can enhance the load-bearing capacity of the support plate 13 and prevent the support plate 13 from bending and deforming due to the weight of the pipeline.

[0028] Reference Figure 3 , Figure 4 The support plate 13 has a tightening screw 15 threaded on one end of each side.

[0029] Specifically, tighten the screw 15 through the support plate 13 and contact the side wall of the groove 16 of the support column 9. After the support plate 13 is adjusted to a suitable height, turn the screw 15 to squeeze the side wall of the groove 16 and firmly fix the support plate 13 on the support column 9 to prevent the support plate 13 from sliding under the weight or vibration of the pipeline and ensure the stability of the pipeline laying position.

[0030] Reference Figure 3 A pipe clamp 12 is fixedly installed on the upper end of the support plate 13, and an adjuster 11 is installed on the upper end of the pipe clamp 12.

[0031] Specifically, the pipe clamp 12 is made of stainless steel and has a ring-shaped structure. It is welded to the support plate 13 to wrap and fix the power cable, preventing the cable from swaying in the trench. The adjuster 11 is a bolt-type structure that can change the tightness of the pipe clamp 12, allowing it to adapt to power cables of different diameters and improving the flexibility of the support structure. The adjuster 11's method of adjusting the tightness of the pipe clamp 12 is a mature and publicly available technology; therefore, its specific structure and working principle will not be elaborated upon in this paper.

[0032] Working principle: During installation, align the first snap-fit ​​block 18 of the second trench segment 4 with the second snap-fit ​​block 19 of the first trench segment 4, and snap-fit ​​them together from top to bottom. Then, connect the water collection pits 5 of the two trench segments 4 through the water pipe 6. Repeat this step to splice the required number of trench segments 4 according to the pipeline laying length to complete the main assembly of the trench. Then, lift the handle 1 to remove the cover plate 3. According to the diameter of the power line, slide the support plate 13 up and down, adjust it to a suitable height, and tighten the screws 15 to fix the support plate 13. Place the pipeline into the pipe clamp 12 at the upper end of the support plate 13, and adjust the adjuster 11 at the upper end of the pipe clamp 12 to make the pipe clamp 12 tightly wrap the pipeline, thus fixing the pipeline. After all pipelines are laid, snap the cover plate 3 back onto the upper end of the trench segment 4 to cover the opening. When the pipeline needs to be inspected, simply lift the handle 1 to remove the cover plate 3, loosen the adjuster 11 of the pipe clamp 12, and the pipeline can be removed. After the inspection is completed, re-fix the pipeline and replace the cover plate 3.
