Description

Technical Field

[0001] This utility model belongs to the technical field of trench construction equipment, and in particular relates to a pipeline trench support structure that can be quickly adjusted. Background Technology

[0002] In the field of water supply and drainage construction, trench excavation is a crucial foundational task. The stability of the trench sidewalls after excavation directly affects construction safety, project quality, and the smooth progress of subsequent pipeline installation. Due to the complex and diverse geological conditions, the pressure and deformation experienced by the trench sidewalls vary significantly across different areas and depths. Therefore, effective support structures are needed to ensure the stability of the trench during construction.

[0003] Traditional pipeline trench support structures typically have several drawbacks. In terms of support adjustment, traditional structures are slow to adapt to varying excavation depths. As trench depth increases, traditional support structures require significant time and manpower for rebuilding or adjustment, undoubtedly extending the construction period and reducing efficiency. For example, in some traditional supports using wood or simple metal bracing, each adjustment necessitates the disassembly and reinstallation of components, a cumbersome and time-consuming process.

[0004] From a stability perspective, the stability of traditional support structures is difficult to guarantee. Some traditional support structures have few contact points with the trench sidewalls, resulting in uneven stress distribution. This makes them prone to deformation, displacement, or even collapse under high pressure on the trench sidewalls or complex geological conditions, posing significant safety hazards to construction. Furthermore, due to the lack of an effective pressure support mechanism, traditional support structures cannot dynamically adjust the support intensity according to actual pressure conditions, failing to provide stable and reliable support for the trench sidewalls.

[0005] In terms of flexibility and adaptability, traditional support structures are often designed in a relatively fixed manner, making it difficult to adapt to different geological conditions and trench sizes. Geological differences in different regions, such as soil type, water content, and groundwater level, all affect the stability of trench sidewalls. Traditional support structures cannot be flexibly adjusted to these changes, resulting in unsatisfactory support effects under some special geological conditions, and even requiring the redesign of support schemes, increasing construction costs and difficulty.

[0006] In summary, existing pipeline trench support structures have many shortcomings in terms of adjustment speed, stability, flexibility, and cost, failing to meet the demands of modern water supply and drainage construction for efficient, safe, and economical support. Therefore, developing a pipeline trench support structure that is quickly adjustable, stable, reliable, flexible, and cost-effective is of significant practical importance. Utility Model Content

Detailed Implementation

[0034] 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 scope of protection of the present utility model. Specific Implementation Example 1:

[0036] Please see Figure 1-8 As shown, this utility model is a quickly adjustable pipeline trench support structure, particularly suitable for support operations during pipeline trench excavation in water supply and drainage construction projects, especially in areas with poor soil structure stability. Its structure includes a support plate assembly and a telescopic pressurizing assembly connecting and supporting the two support plate assemblies. The support plate assembly includes a support plate 1, a support connecting rod 2, and positioning seats 3. Two positioning seats 3 are snapped onto the support plate 1. The support connecting rod 2 is rotatably mounted on the two positioning seats 3. The telescopic pressurizing assembly includes a guide groove 4, two connecting sleeves 5, and a jack 6. The jack 6 is a hydraulic jack or a mechanical jack that can be laid flat. A connecting sleeve 5 is slidably guided at each end of the guide groove 4. The jack 6 is installed inside the guide groove 4 to extend the two connecting sleeves 5. The connecting sleeves 5 are sleeved onto the support connecting rod 2 and connected and positioned by pins 7.

[0037] The support plate 1 includes a rectangular plate 11. Two rectangular frame plates 12, symmetrical about the vertical centerline of the rectangular plate 11, are fixed to one side of the rectangular plate 11. Cylindrical rods 13 are fixed between the upper and lower inner walls of the rectangular frame plates 12. A row of rectangular slots 14 is formed on the opposite sidewalls at the outer ends of the rectangular frame plates 12.

[0038] The positioning seat 3 includes a rectangular base plate 31. A slider 32, which is placed inside a rectangular frame plate 12, is fixed to the inner side of the rectangular base plate 31. An oblong through hole 33, which mates with a cylindrical rod 13, is provided between the upper and lower ends of the slider 32. Two pairs of rectangular locking blocks 34, which mate with rectangular locking slots 14, are fixed to the inner side of the rectangular base plate 31. A seated bearing 35 is installed on the outer side of the rectangular base plate 31.

[0039] The support link 2 includes a round rod 21 that connects to two bearings 35. A sector-shaped reinforcing plate 22, tangentially fitted to a rectangular plate 11, is fixed to the center of the round rod 21. A rectangular link 23 is fixed to the round rod 21 and the sector-shaped reinforcing plate 22. A first pin hole 24, fitted to a pin 7, is provided on the rectangular link 23. When the support link 2 on the support plate assembly needs to change position, the two positioning seats 3 are pulled outwards, the rectangular locking block 34 disengages from the rectangular slot 14 on the support plate 1, and the end of the oblong through hole 33 adjacent to the support plate 1 contacts the cylindrical rod 13. After the positioning seat 3 moves vertically to a new position, the rectangular locking block 34 on the positioning seat 3 re-engages into the rectangular slot 14, the end of the oblong through hole 33 adjacent to the support link 2 contacts the cylindrical rod 13, and the inner end of the slider 32 abuts against the rectangular plate 11. The positioning seat 3 contacts the support plate 1 at multiple points, distributing the force. The support rod 2 applies force to the two positioning seats 3 at both ends, and the central fan-shaped reinforcing plate 22 applies force directly to the support plate 1.

[0040] Among them, the fan-shaped reinforcing plate 22 has several through holes 25, which achieves the purpose of reducing the overall mass of the support connecting rod 2 while ensuring structural strength, reducing material costs and facilitating operation.

[0041] The guide groove 4 includes a rectangular groove 41 with an upper opening. A rectangular guide hole 42 is provided at each end of the rectangular groove 41. The connecting sleeve 5 includes a rectangular tube 51 that slides axially with the rectangular connecting rod 23. A row of second pin holes 52 are provided on the upper and lower walls of the rectangular tube 51 to mate with the pin 7, allowing adjustment of the effective length between the rectangular tube 51 and the rectangular connecting rod 23 to accommodate different widths of pipe trenches and different inclination angles of the support connecting rod 2. The rectangular tube 51 slides with the rectangular guide holes 42. A rectangular end plate 53 is fixed to one end of the rectangular tube 51. The two ends of the jack 6 rest on the two rectangular end plates 53.

[0042] Support structure installation: Support plate assemblies are installed on both sides of the excavated pipe trench. Support plate 1 is attached to the side wall of the trench, positioning seat 3 is snapped onto support plate 1, and support connecting rod 2 is rotatably installed between the two positioning seats 3.

[0043] Install the telescopic pressurization assembly: The connecting sleeve 5 passes through the inside of the guide groove 4, the connecting sleeve 5 is sleeved on the support rod 2 and connected and positioned by the pin 7, and the jack 6 is installed in the guide groove 4.

[0044] Support plate assembly adjustment: During excavation, as the trench depth increases on each side, the support plate assembly needs to be moved downwards sequentially. First, manually retract the jack 6 to release its tension. Remove the corresponding pin 7 to disconnect the connecting sleeve 5 from the support rod 2. Move the support plate assembly down to the desired position, while simultaneously adjusting the position of the positioning seat 3 at the bottom of the support rod 2 to ensure a tight fit between the support plate 1 and the trench sidewall. Reinsert the pin 7 to connect the support plate assembly to the telescopic pressurization assembly.

[0045] Pressure support for the support plate assembly: The jacks 6 are manually extended to push the two connecting sleeves 5 outwards, thereby applying pressure to the support plate assembly and achieving pressure support for the support plates 1 on both sides. The extension force of the jacks 6 is adjusted to ensure that the support plate assembly stably and reliably supports the trench sidewalls and prevents collapse.
