[0002] In highway engineering, embankment refers to the fill roadbed that is higher than the original ground. Its function is to support the roadbed and road surface, and connect with the road cutting to form a complete line. High embankment is an embankment that reaches a certain standard in height, usually an embankment with a height greater than 20m. High embankments are more common in mountainous and hilly areas with complex terrain.

A plurality of water outlet holes 214 are provided on the peripheral wall of the connecting rod 21, and all the water outlet holes 214 are arranged at intervals along the length direction of the connecting rod 21, and each water outlet hole 214 is connected to the flow channel 213; a pushing bar 26 is slidably installed in the water storage chamber 25, and the pushing bar 26 is provided with a driving component 7, and the driving component 7 is used to drive the pushing bar 26 to rise and fall so as to push the rainwater in the water storage chamber 25 into the flow channel 213 of the connecting rod 21.

[0050] Reference Figure 7 In this embodiment, the driving assembly 7 includes a driving screw rod 71 and a driving hand wheel 72. The driving screw rod 71 is vertically arranged and rotatably installed in the water storage chamber 25. The driving screw rod 71 is penetrated by the pushing bar 26 and is threadedly connected with the pushing bar 26. One end of the driving screw rod 71 passes through the water storage chamber 25 and is connected with a rotating head 711. The cross-sectional shape of the rotating head 711 is polygonal; the driving hand wheel 72 has a rotating groove 721 for the rotating head 711 to be matched and inserted. When the rotating head 711 is matched and inserted in the rotating groove 721, the driving hand wheel 72 and the driving screw rod 71 are circumferentially linked (that is, the driving hand wheel 72 can drive the driving screw rod 71 to rotate), and the driving hand wheel 72 and the driving screw rod 71 are detachably connected through the rotating head 711.

[0051] The implementation principle of Example 2 of the present application is as follows: for areas with low precipitation, a reinforcing strip 2 with a water storage chamber 25 is selected. The water storage chamber 25 can be used to collect and store rainwater. When the vegetation growing on the slope 11 or the step surface 12 needs to be watered, the driving screw 71 is driven to rotate by the driving hand wheel 72 to drive the pushing strip 26 to rise and fall. The pushing strip 26 can push the rainwater collected in the water storage chamber 25 into the flow channel 213 of the connecting rod 21, and then discharge it to the step surface 12 of the base layer 1 through the water outlet 214 for absorption by vegetation, thereby improving the utilization rate of rainwater.

[0052] Embodiment 3: The embodiment of the present application discloses a construction method of a high embankment.

[0053] Reference Figure 8 The difference between the construction method of the high embankment disclosed in the embodiment of the present application and that in embodiment 2 is that: In this embodiment, an installation groove 252 is opened on the inner wall of the water storage chamber 25, and the driving assembly 7 includes a rotating disk 73, a return spring 74, a first connecting rod 75, a second connecting rod 76 and a driving member. The rotating disk 73 is rotatably installed on the inner wall of the installation groove 252, and the return spring 74 is installed between the push bar 26 and the inner wall of the water storage chamber 25. One end of the return spring 74 is fixedly connected to the top wall of the water storage chamber 25, and the other end is fixedly connected to the push bar 26. The return spring 74 normally moves the push bar 26 to the bottom of the water storage chamber 25.

[0054] Reference Figure 8 The driving member includes a pedal 77 and a third connecting rod 78. The pedal 77 is located at the top of the reinforcing strip 2. The third connecting rod 78 is vertically arranged. One end of the third connecting rod 78 is connected to the pedal 77, and the other end is slidably penetrated through the reinforcing strip 2 and extends into the water storage chamber 25. The pedal 77 is slidably installed on the reinforcing strip 2 through the third connecting rod 78; the first connecting rod 75 and the second connecting rod 76 are both in the shape of long strips. One end of the first connecting rod 75 is hinged to the rotating disk 73, and the other end is hinged to the pushing strip 26. One end of the second connecting rod 76 is hinged to the rotating disk 73, and the other end is hinged to the third connecting rod 78. When the second connecting rod 76 descends, the rotating disk 73 rotates and the pushing strip 26 is lifted to push the rainwater in the water storage chamber 25 into the flow channel 213 of the connecting rod 21.

[0055] The implementation principle of Example 3 of the present application is as follows: when the vegetation needs to be watered, the pedal 77 is stepped on to force the pedal 77 to sink, and the pedal 77 pushes the second connecting rod 76 through the third connecting rod 78 to drive the rotating disk 73 to rotate, and then the push bar 26 can be driven to lift under the action of the first connecting rod 75, thereby greatly improving the convenience of operation for taking out rainwater from the water storage chamber 25; after the push bar 26 is lifted, the reset spring 74 is deformed and has elastic force. When people lift their feet, the elastic force enables the push bar 26 to reset, so that the water storage chamber 25 can regain the ability to collect rainwater, thereby greatly improving the convenience of operation of the overall structure.

[0056] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
