Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline construction, in particular to a pipe trench supporting structure. Background Art

[0002] With the rapid development of urban construction, the construction and improvement of underground pipeline networks have become particularly important. The narrowness of urban roads and the increasingly dense traffic and pedestrian flow have made pipeline construction face many challenges and safety hazards. In such an environment, trench excavation work has certain safety hazards.

[0003] Currently, trench support primarily utilizes wooden planks, steel sheet piles, or channel steel spliced ​​together, supported by crossbeams. Each support component has a small contact area with the trench wall, resulting in numerous joints. If the positioning of adjacent support components deviates, resulting in joints that do not meet requirements, the support can become unstable and even collapse. Furthermore, installing or disassembling each component individually is extremely inconvenient, inefficient, time-consuming, and labor-intensive. Furthermore, to save costs and labor, construction teams and workers often use single-point support or no support for excavated trenches. Single-point support has a small contact area and is unstable, often causing trench collapses at on-site joints. Vehicles or people traveling near the trench could fall or be injured. Trench collapses also require rework, wasting time and costs. Utility Model Content

[0030] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0031] In this embodiment, please refer to Figures 1 to 5 The utility model provides a pipe trench support structure, comprising:

[0032] A support device 2, comprising a plurality of support mechanisms 21 and a plurality of support mechanisms 22, wherein the support mechanisms 22 are used to support the support mechanisms 21 on both sides of the connecting trench in the width direction;

[0033] The support mechanism 21 includes a support plate 211, a support tip 212, a trapezoidal penetration block 213, a vertical groove 214 and two circular grooves 215. The support tip 212 is fixedly connected to the bottom of the support plate 211, and the upper bottom of the trapezoidal penetration block 213 is fixedly connected to one side of the support plate 211 facing the length direction of the trench. The support plate 211 has a penetration groove 216 on the other side facing the length direction of the trench, which cooperates with the trapezoidal penetration block 213. The vertical groove 214 is fixedly connected to the side of the support plate 211 facing the center direction of the trench. The two circular grooves 215 are symmetrically arranged along the vertical groove 214 and are located on the same side of the support plate 211 as the vertical groove 214. The top of the support plate 211 has a tip groove 217 that cooperates with the support tip 212.

[0034] Through the trapezoidal connecting blocks 213 and the corresponding connecting grooves 216, the support plates 211 can be quickly spliced ​​in the length direction of the trench, thereby ensuring the tightness of the connection between adjacent support plates 211, facilitating installation and disassembly, and ensuring the positioning of the entire support mechanism 21, avoiding excessive joints, and providing good support performance, thereby enhancing the stability of the entire support structure and reducing the occurrence of collapse accidents. The cooperation between the support tip 212 and the tip groove 217 allows the support plates 211 to be stacked layer by layer in the vertical direction. When the trench support depth needs to be increased, the support tip 212 can be inserted into the tip groove 217 of the upper support plate 211, which increases the overall stability of the support structure and improves versatility and practicality.

[0035] In this embodiment, please refer to Figure 1 The support tip 212 is tapered. When the support tip 212 contacts the ground, its shape allows for easier insertion into the soil. When the tapered tip bears vertical pressure, stress is concentrated at the tip and then gradually dispersed into the surrounding soil.

[0036] In this embodiment, please refer to Figure 2 and Figure 3The support mechanism 22 includes a hollow support tube 221, two support rods 222, two racks 223, a spreading gear 224, a rotating shaft 225, a spreading power member 226, and two sets of support assemblies 227. The rotating shaft 225 is rotatably arranged in the middle of the inner side of the hollow support tube 221. The spreading gear 224 and the rotating shaft 225 are coaxially fixedly matched. The spreading gears 224 are meshed with the two racks 223 for transmission. One end of the two racks 223 is respectively fixedly connected to one end of the two support rods 222. Two sets of support assemblies 227 are respectively fixedly connected to the other ends of the two support rods 222. The two support rods 222 are slidably matched with the inner wall of the hollow support tube 221. The spreading power member 226 drives the rotating shaft 225 to rotate, driving the two racks 223 to move in the opposite direction. The backs of the two racks 223 are respectively slidably matched with the inner wall of the hollow support tube 221. By driving the rotating shaft 225 to rotate through the expansion power part 226, the rotating shaft 225 drives the expansion gear 224 to rotate, thereby causing the two racks 223 to move in opposite directions, and the extension length of the two support rods 222 can be accurately controlled, thereby adjusting the expansion degree of the support assembly 227 to adapt to different trench support widths.

[0037] In this embodiment, please refer to Figure 3 The expansion power member 226 includes a motor, which is wirelessly controlled to improve the flexibility and safety of operation.

[0038] In this embodiment, please refer to Figure 2 and Figure 3 Each support assembly 227 includes a first support rod 2271, a second support rod 2272 arranged to cross the first support rod 2271, two first support columns 2273 respectively fixed vertically to the two ends of the first support rod 2271, two second support columns 2274 respectively fixed vertically to the two ends of the second support rod 2272, and a central support column 2275 vertically fixed to the intersection of the first support rod 2271 and the second support rod 2272. The other end of the support rod 222 is vertically fixed to the intersection of the first support rod 2271 and the second support rod 2272. When in use, the first support column 2273 and the second support column 2274 are placed in the circular groove 215, and the central support column 2275 is placed in the vertical groove 214. The first support rod 2271 and the second support rod 2272 in each support assembly 227 are cross-arranged, and the central support column 2275 is vertically fixed at the intersection position. At the same time, the first support column 2273 and the second support column 2274 are respectively provided at both ends to form multiple triangular stable structures. The stability of the triangle enables the support assembly 227 to effectively resist forces in various directions.

[0039] In this embodiment, please refer to Figure 2 and Figure 3The intersection of the first support rod 2271 and the second support rod 2272 and the vertical fixed position of the other end of the support rod 222 are both provided with reinforcing ribs 2276. The reinforcing ribs 2276 can significantly improve the structural strength of the intersection and the fixed position, enhance the stability of the support mechanism 22, and improve safety.

[0040] In this embodiment, please refer to Figure 4 , further comprising a clamping mechanism 23, the clamping mechanism 23 being used to clamp and fix the support mechanism 21; the clamping mechanism 23 can be used for clamping and fixing protection of the support mechanism 21 during transportation, or the clamping mechanism 23 can be provided on a device for installing the support mechanism 21 to clamp and fix the clamping mechanism 23, wherein the device for installing the support mechanism 21 adopts an existing one and will not be described in detail here;

[0041] The clamping mechanism 23 includes two relatively arranged supports 231, a slide rail 232, a rotating rod 233 rotatably connected to the two supports 231, two L-shaped seats 234, and a clamping power piece 235 that drives the rotating rod 233 to rotate. The bottom of the horizontal part of the L-shaped seat 234 slides with the slide rail 232, and the top of the horizontal part of the L-shaped seat 234 has a support groove 236 that cooperates with the support tip 212. The side of the vertical part of the L-shaped seat 234 has a guard groove 237 that is connected to the support groove 236 and cooperates with the support plate 211. The rotating rod 233 is symmetrically provided with thread lines with opposite rotation directions along its middle part. The horizontal parts of the two L-shaped seats 234 are respectively threadedly engaged with the thread lines of different rotation directions on the rotating rod 233. The rotating rod 233 is driven to rotate by the clamping power piece 235, driving the two L-shaped seats 234 to move toward or in the opposite direction.

[0042] The clamping power member 235 drives the rotating rod 233 to rotate, causing the two L-shaped seats 234 to move toward or in opposite directions, allowing precise adjustment of the L-shaped seat position, thereby precisely controlling the clamping force and position of the support plate 211 and the support tip 212. The bottom of the horizontal portion of the L-shaped seat slides with the slide rail 232, ensuring the stability of the L-shaped seat during movement. The support grooves 236 on the top of the horizontal portion of the two L-shaped seats 234 cooperate with the support tip 212, and the protective grooves 237 on the side of the vertical portion cooperate with the support plate 211, allowing the L-shaped seat to provide good support and protection for the support plate 211 and the support tip 212. When the support plate 211 is placed on the L-shaped seat, the support grooves 236 prevent the support tip 212 from shaking, and the protective grooves 237 limit the horizontal displacement of the support plate 211, thereby enhancing stability.

[0043] In this embodiment, please refer to Figure 4 The clamping power member 235 includes an electric motor or a hydraulic motor.

[0044] In this embodiment, please refer to Figure 2 or Figure 3 The support rod 222 is provided with a scale line 2277, which can provide an accurate reference for adjusting the support rod 222. In scenarios where the support rod 222 needs to be built or adjusted multiple times, the scale line 2277 can help achieve consistency in operation.

[0045] Working principle: When in use, the support plates 211 can be quickly spliced ​​in the length direction of the trench through the trapezoidal connection blocks 213 and the corresponding connection grooves 216, thereby ensuring the tightness of the connection between adjacent support plates 211, facilitating installation and disassembly, and ensuring the position of the entire support mechanism 21, avoiding excessive joints, and having good support performance, thereby enhancing the stability of the entire support structure and reducing the occurrence of collapse accidents. In the depth direction of the trench, the support tip 212 and the tip groove 217 are coordinated to enable the support plates 211 to be stacked layer by layer in the vertical direction. When the trench support depth needs to be increased, the support tip 212 can be inserted into the tip groove 217 of the upper support plate 211, thereby increasing the overall stability of the support structure and improving versatility and practicality. The two ends of the trench are supported and connected by a support mechanism 22. The first and second support columns 2273, 2274 are placed in the circular groove 215, and the center support column 2275 is placed in the vertical groove 214. The first and second support rods 2271, 2272 of each support assembly 227 are intersected, and the center support column 2275 is fixed perpendicularly to the intersection. The first and second support columns 2273, 2274 are provided at each end, forming a plurality of triangular stable structures. The stability of the triangle enables the support assembly 227 to effectively resist forces from various directions. The clamping power member 235 drives the rotating rod 233 to rotate, driving the two L-shaped seats 234 to move toward or in opposite directions, allowing precise adjustment of the L-shaped seat position, thereby precisely controlling the clamping force and position of the support plate 211 and the support tip 212.

[0046] In summary, the utility model uses the trapezoidal connecting blocks 213 and the corresponding connecting grooves 216 to enable the support plates 211 to be quickly spliced ​​in the length direction of the trench, thereby ensuring the tightness of the connection between adjacent support plates 211, facilitating installation and disassembly, and ensuring the position of the entire support mechanism 21, avoiding excessive joints, and providing good support performance, thereby enhancing the stability of the entire support structure and reducing the occurrence of collapse accidents. The cooperation between the support tip 212 and the tip groove 217 enables the support plates 211 to be stacked layer by layer in the vertical direction. When the trench support depth needs to be increased, the support tip 212 can be inserted into the tip groove 217 of the upper support plate 211, thereby increasing the overall stability of the support structure. The utility model improves versatility and practicality; by driving the rotating shaft 225 to rotate by the opening power member 226, the rotating shaft 225 drives the opening gear 224 to rotate, thereby causing the two racks 223 to move in opposite directions, and can accurately control the extension length of the two support rods 222, thereby adjusting the expansion degree of the support assembly 227 to adapt to different trench support widths; by cross-arranging the first support rod 2271 and the second support rod 2272 in each support assembly 227, and vertically fixing the central support column 2275 at the intersection position, and providing the first support column 2273 and the second support column 2274 at both ends, a plurality of triangular stable structures are formed. The stability of the triangle enables the support assembly 227 to effectively resist forces in various directions. Therefore, the utility model effectively overcomes the various shortcomings of the existing technology and has high industrial utilization value.
