[0041] S200, cutting or selecting the side pressing plate 2 according to the length of the slope surface of the trench 1 and attaching the side pressing plate 2 to the slope surface of the trench 1;

[0042] S300, placing the groove bottom pressing plate 3 and the groove weir pressing plate 4 at the bottom and the top of the trench 1 respectively, which can be connected with the side pressing plate 2, and fixing the groove bottom pressing plate 3 and the groove weir pressing plate 4 by using the anchoring members 5

[0043] S400, standing the vertical partition plate 6 on the groove bottom pressing plate 3 and adjusting the distance between the vertical partition plate 6 and the side pressing plate 2 to the appropriate size of the side flow channel, and then fixing the position of the vertical partition plate 6 by using the fixing mechanism.

[0044] The pipe network trench supporting device and method provided by the present embodiment can be directly attached to the slope surface of the trench 1 through the cooperation of the side pressing plate 2, the groove bottom pressing plate 3, the groove weir pressing plate 4 and the plurality of anchoring members 5, which can avoid the direct erosion of rainwater to the slope surface of the trench 1; meanwhile, the side flow channel formed between the vertical partition plate 6 and the side pressing plate 2 can accumulate a certain amount of water, so that the side flow channel has a higher water level, thereby further reducing the erosion intensity of rainwater to the slope surface of the trench 1, and more rainwater can flow along the side flow channel to the downstream, reducing the erosion of rainwater to the bottom of the trench 1; through such a structure, temporary support can be quickly realized to cope with rainy weather, which has a good protection effect on the trench 1, and after the rain, the device can be conveniently removed and recycled.

[0045] As Figures 1 to 3 The application provides the following specific implementation based on the first embodiment:

[0046] The fixing mechanism comprises two pulling assemblies and a plurality of pressing assemblies. One pulling assembly is connected with the lower part of the vertical partition plate 6 and the groove bottom pressing plate 3 respectively, and the other pulling assembly is connected with the upper part of the vertical partition plate 6 and the groove weir pressing plate 4 respectively. The pressing assemblies are all supported between the side pressing plate 2 and the vertical partition plate 6 and located at the middle part of the vertical partition plate 6 to cooperate with the two pulling assemblies to fix the vertical partition plate 6.

[0047] The pressing assembly comprises a threaded cylinder 7, a threaded rod 8, a screwing block 9, a pressing head 11 and a screwing handle 12. The threaded cylinder 7 is hinged with the vertical partition plate 6. One end of the threaded rod 8 is matched with the threaded cylinder 7 through a threaded structure. The screwing block 9 is arranged at the other end of the threaded rod 8. The screwing handle 12 is arranged on the screwing block 9 to facilitate people to manually or by using a tool to rotate the threaded rod 8 through the screwing handle 12. The operation is convenient. The pressing head 11 is arranged on the screwing block 9. The middle part of the side pressing plate 2 is provided with a pressing groove 10. The pressing head 11 is inserted into the pressing groove 10 to support the pressing assembly between the side pressing plate 2 and the vertical partition plate 6. The length of the pressing can be adjusted through the adjustable threaded rod 8 and the threaded cylinder 7 in the pressing assembly. The screwing block 9 facilitates the operation of rotating the threaded rod 8. The pressing head 11 inserted into the pressing groove 10 can effectively prevent slipping.

[0048] The pulling assembly comprises a lower pulling line 19 and an upper pulling line 16. The two ends of the lower pulling line 19 are connected with the lower end of the vertical partition plate 6 and one side of the groove bottom pressing plate 3 and the side pressing plate 2 respectively. The two ends of the upper pulling line 16 are connected with the upper end of the vertical partition plate 6 and the groove weir pressing plate 4 respectively. The upper and lower parts of the vertical partition plate 6 can be pulled through the pulling assembly to improve the stability and the pressing strength of the pressing assembly. Meanwhile, the setting of the lower pulling line 19 enables the groove bottom pressing plate 3 and the side pressing plate 2 to pull the side pressing plate 2 downward when the water level difference between the two sides of the side pressing plate 2 is relatively large, to resist the action of the buoyancy and avoid the side pressing plate 2 from floating upward to form a too large leakage channel.

[0049] The pulling assembly further comprises a U-shaped wheel frame 13, a wire guide wheel 14, a wire guide transverse plate 15 and a pressing piece 17. The U-shaped wheel frame 13 is arranged on the groove weir pressing plate 4. The wire guide wheel 14 and the wire guide transverse plate 15 are arranged side by side on the U-shaped wheel frame 13. One end of the upper pulling line 16 is wound on the wire guide wheel 14, and the middle part is arranged on the wire guide transverse plate 15. The other end is connected with the upper end of the vertical partition plate 6. The pressing piece 17 is arranged on the U-shaped wheel frame 13 and cooperates with the wire guide transverse plate 15 to press the middle part of the upper pulling line 16 on the wire guide transverse plate 15, so that the vertical partition plate 6 can be conveniently fixed.

[0050] The anchoring member 5 is a soil nail, the groove bottom pressing plate 3 and the groove weir pressing plate 4 are provided with a pry groove 18 on one side of the anchoring member 5, the pry groove 18 makes the cap portion of the soil nail suspended; the side pressing plate 2 is fixedly connected, crimped or hinged between the side pressing plate 2 and the groove bottom pressing plate 3 and between the side pressing plate 2 and the groove weir pressing plate 4.

[0051] The pipe network trench supporting device comprises two slope protection units, and the two slope protection units are respectively located on the two side slope surfaces of the trench 1.

[0052] In a specific embodiment, the groove bottom pressing plates 3 of the two slope protection units are connected to each other and cover the bottom of the trench 1.

[0053] The vertical partition plates 6 of the two slope protection units are provided with a damping and energy dissipation assembly; the damping and energy dissipation assembly comprises a conducting column 20, an outer shell 21, a spiral elastic sheet 22, a sealing member 23 and an energy dissipation filling body 24, the outer shell 21 is a cylindrical structure, one end of the conducting column 20 is connected to the side pressing plate 2 of one of the slope protection units, the other end is inserted into the outer shell 21, the outer shell 21 is connected to the side pressing plate 2 of the other slope protection unit, the spiral elastic sheet 22 is arranged between the conducting column 20 and the outer shell 21 and is connected to the conducting column 20 and the outer shell 21 respectively, so that a spiral cavity is formed between the conducting column 20 and the outer shell 21, an air bag 25 is arranged on the spiral elastic sheet 22 along the extension direction of the spiral elastic sheet 22, and the air bag 25 is inflated and deflated through an inflation port arranged on the outer shell 21, the energy dissipation filling body 24 is in a liquid or semi-solid state and is filled in the spiral cavity, and the sealing member 23 is arranged at the opening of the outer shell 21 and is sealingly connected to the conducting column 20 and the outer shell 21 respectively to prevent the energy dissipation filling body 24 from leaking out.

[0054] Specifically, the energy dissipation filling body 24 adopts a shear thickening fluid. The air bag 25 is located in the middle of the spiral elastic sheet 22. The conducting column 20 is in a telescopic screw structure; the outer ends of the conducting column 20 and the outer shell 21 are provided with hanging sheets 26, and the side pressing plate 2 is provided with a hanging groove 27 for hanging the hanging sheets 26.

[0055] During installation, after the side pressing plates 2 of the slope protection units on both sides of the trench 1 are fixed, the conducting column 20 is adjusted to an appropriate length, so that the hanging sheets 26 on the conducting column 20 and the outer shell 21 can be hung on the hanging groove 27, and then the air bag 25 is inflated through the inflation port, so that the pressure in the spiral cavity is maintained in an appropriate state.

[0056] In use, when rain impact causes the side pressure plate 2 to vibrate, the vibration is transmitted to the conducting column 20 and the outer shell 21, and the relative movement between the conducting column 20 and the outer shell 21 causes the spiral elastic sheet 22 to deform, and the spiral elastic sheet 22 exerts force on the energy dissipation filling body 24 in the spiral cavity, and the vibration kinetic energy is converted into internal energy by the elasticity of the spiral elastic sheet 22 and the friction of the energy dissipation filling body 24. The energy dissipation filling body 24 is a shear thickening fluid, which hardens when the vibration is intense, so that when the impact of the rain on the side pressure plate 2 is relatively large, the energy dissipation filling body 24 is impacted and hardened, and the rigidity between the side pressure plates 2 of the two slope protection units is greatly enhanced, thereby improving the overall impact resistance.

[0057] The setting of the shock absorption and energy dissipation assembly can exert a certain pressure on the side pressure plates 2 of the two slope protection units, thereby reducing the possibility of floating.

[0058] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0059] It should be noted that the terms used herein are only intended to describe specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and furthermore, it should be understood that when the terms "comprise" and / or "include" are used in the specification, there is a feature, step, operation, device, component and / or combination thereof.
