Description

Technical Field

[0001] This utility model belongs to the field of urban pipeline construction technology, and in particular relates to a slope reinforcement device for urban pipeline construction. Background Technology

[0002] Urban pipeline construction areas are often located in densely populated areas with buildings, roads, and complex underground pipelines. Especially when excavating trenches in soft, fine-grained soil layers, slope stability is a critical safety issue. Due to their loose structure and high permeability, gravelly soil layers are prone to seepage damage under the influence of groundwater, leading to slope instability of the trench.

[0003] Traditional trench slope protection often uses closed steel sheet piles or retaining plates. These types of protection are prone to causing pore water pressure to accumulate in gravel layers, leading to seepage damage. Existing slope protection devices have poor reliability in loose gravel and limited drainage effect.

[0004] In the reinforcement of gravel slopes during urban pipeline construction, drainage reinforcement is an effective method to reduce pore water pressure and minimize seepage damage. However, traditional closed-type support has poor adaptability, easily causes water pressure accumulation, and is difficult to adapt to the seepage characteristics of gravel layers. Furthermore, traditional slope support devices have relatively complex structures, poor anchoring effects, and low support efficiency. Utility Model Content

[0007] A slope reinforcement device for urban pipeline construction includes a trench slope. Several equally spaced support modules are provided on both sides of the trench slope. The support modules are fixedly connected to the trench slope through anchoring devices. The anchoring devices on both sides of the trench slope are hinged together by a crossbar assembly.

[0008] The support module includes a hollow slope plate. The hollow slope plate has an upper drainage outlet and a lower drainage outlet at both ends along the slope direction. Several equally spaced drainage fins are fixedly connected to the side of the hollow slope plate facing the slope. Several seepage holes are opened on the top surface of the drainage fins and the side of the hollow slope plate facing the slope. Geotextile is provided on the side of the hollow slope plate facing the slope.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Example

[0028] like Figures 1-4 As shown, a slope reinforcement device for urban pipeline construction is used for slope support during trench excavation in soft, fine gravel strata. It includes a trench slope 1, with several support modules evenly distributed on both sides of the trench slope 1, which are reliably fixed to the trench slope 1 through anchoring devices.

[0029] like Figure 1 , Figure 2As shown, the support module includes a hollow slope plate 2. The hollow slope plate 2 adopts a double-layer structure design. At both ends along the slope direction, there are upper drainage outlets 3 and lower drainage outlets 4 respectively. Water from the top of the slope can enter through the upper drainage outlet 3 and exit through the lower drainage outlet 4, forming a complete drainage channel. Several drainage fins 5 are fixedly connected at equal intervals on the side of the hollow slope plate 2 facing the slope. The drainage fins 5 adopt a hollow rectangular structure, and their inner cavity is connected to the hollow slope plate 2 to form a continuous drainage system.

[0030] The bottom of the support module is equipped with a drainage ditch 101, which collects seepage water from the lower drainage outlet 4 and possible surface runoff to prevent water accumulation at the slope toe and avoid adverse effects on slope stability. The top of the support module is equipped with a water guide plate 8, which is designed to guide surface water into the upper drainage outlet 3 to prevent rainwater and other surface water from directly scouring the slope surface or seeping into the slope body.

[0031] The top surface of the drainage fins 5 and the side of the hollow slope plate 2 facing the slope are provided with several seepage holes 6 to prevent water pressure accumulation from causing slope instability. They can effectively collect seepage water in the gravel layer and prevent the loss of gravel particles from causing soil cavities. The side of the hollow slope plate 2 facing the slope is provided with geotextile 7, which plays a filtering role that allows water to pass through but not soil, effectively avoiding slope instability caused by water accumulation.

[0032] like Figure 5 , Figure 6 As shown, the anchoring device includes an anchoring flange 9, which is snapped together with two or four adjacent hollow slope plates 2. This one-to-many connection not only simplifies the installation process but also concentrates the load of multiple slope plates, improving the anchoring efficiency. Both the hollow slope plate 2 and the anchoring flange 9 are provided with threaded holes, and the hollow slope plate 2 and the anchoring flange 9 are fixedly connected by bolts. The bottom end of the anchoring flange 9 is fixedly connected with a threaded rod 10, and the outer end of the threaded rod 10 is threadedly connected with a limit nut 11. Rotating the anchoring flange 9 can drive the threaded rod 10 to rotate within the limit nut 11, and the position of the threaded rod 10 can be adjusted.

[0033] An anchoring cylinder 12 is fixedly connected to the outer end of the limiting nut 11. A stiffening plate 13 and a spiral blade 15 are fixedly connected to the outer end of the anchoring cylinder 12. A drill bit 14 is fixedly connected to the bottom end of the stiffening plate 13. The stiffening plate 13 enhances the structural strength of the anchoring cylinder 12. The spiral blade 15 can effectively cut into the gravel layer and increase the friction area with the gravel during the screwing process. An adjusting anchor head 16 is rotatably connected to the bottom end of the threaded rod 10. The adjusting anchor head 16 is rotatably connected to two symmetrically arranged adjusting rods 17 through a pin.

[0034] The end of the adjusting rod 17 away from the adjusting anchor head 16 is rotatably connected to the anchoring shovel 18 via a pin. The outer end of the anchoring cylinder 12 has a through T-shaped hole 19. The anchoring shovel 18 is connected to the T-shaped hole 19 via the base 20. When the upper threaded rod 10 moves downward along the anchoring cylinder 12, the adjusting anchor head 16 pushes the adjusting rod 17, causing the anchoring shovel 18 to open outward, forming an enlarged anchoring surface in the gravel layer, which improves the anchoring reliability in loose gravel. When dismantling, the threaded rod 10 is rotated in the opposite direction to retract the anchoring shovel 18, which facilitates the removal of the entire anchoring device and meets the requirement that the temporary support device can be reused.

[0035] like Figure 1 , Figure 2 As shown, the crossbar assembly includes an adjusting rod 21. Both ends of the adjusting rod 21 are hinged to the top of the anchoring flanges 9 on both sides of the slope, improving the overall stability of the slope support system. A sleeve 22 is sleeved on the outer end of the adjusting rod 21. Both ends of the sleeve 22 are provided with adjusting nuts 23, which are threaded to the adjusting rod 21. The effective length of the adjusting rod 21 can be adjusted by adjusting the nuts 23 to adapt to trenches of different widths. When the crossbar assembly is used to temporarily support the pipeline, the gravity load of the pipeline is transmitted to the anchoring flanges 9 on both sides through the adjusting rod 21, and then to the anchoring device, converting the gravity of the pipeline into anchoring reinforcement force. The heavier the pipeline, the greater the pressure transmitted to the anchoring device through the crossbar assembly. The normal pressure of the anchoring device in the gravel layer increases accordingly, thereby improving the friction between the anchoring device and the gravel layer and the anchoring bearing capacity.

[0036] During installation, first place the support module at the corresponding position on the trench slope, insert the drainage fins 5 into the gravel layer, screw the anchoring device into the gravel layer, then rotate the anchoring flange 9 to drive the anchoring shovel 18 to open and form an anchor. Then, fix the hollow slope plate 2 to the anchoring flange 9 with bolts. Finally, install the crossbar assembly, adjust the length by adjusting the nut 23, and then hinge it to the anchoring flanges 9 on both sides.

[0037] During use, seepage water in the gravel layer enters the inner cavity of the drainage fin 5 through the seepage hole 6, then flows into the internal space of the hollow slope plate 2, and finally is discharged through the lower drainage outlet 4, and finally flows into the drainage ditch 101 for centralized discharge, effectively preventing slope instability caused by water pressure accumulation. The crossbar assembly provides mutual support for the slopes on both sides, improving the overall stability.

[0038] In this invention, drainage fins are used to actively collect seepage water from the gravel layer. Combined with the synergistic effect of the expansion anchoring device and the crossbar assembly, a complete slope reinforcement system is formed, which can shorten the support time and improve construction efficiency and safety.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
