Description

Technical Field

[0001] The present application relates to the field of embankment support, and in particular to a steep slope embankment support and protection structure. Background Art

[0002] A steep embankment is a civil engineering structure used for high fill sections of roads or railways, especially when crossing valleys, rivers or other low-lying areas. The side slopes of a steep embankment are steeper and the angle with the horizontal plane is larger, which helps to reduce the amount of fill and save space. Due to the steep slope, steep embankments require special attention to their stability to prevent landslides or erosion.

[0003] The most common method of retaining and protecting steep embankments is to first lay a protective interception fence on the embankment, then lay evenly distributed hollow bricks on the fence, and then fill the hollow parts of the hollow bricks with soil and plant green plants.

[0004] The stability of existing hollow brick paving mainly relies on its own weight against the slope of the embankment. The hollow bricks contact each other to form a complete protective structure. However, in practice, the hollow bricks are only supported by the slope of the embankment and contact each other. When it rains or vibrates, the hollow bricks may slide down the slope of the embankment. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the hollow bricks proposed in the above-mentioned background technology are only supported by the slope of the embankment and conflict with each other, and the hollow bricks may slide down the slope of the embankment when it rains or vibrates. The present application provides a steep slope embankment support and protection structure.

[0008] By adopting the above technical solution, the fixed support mechanism is fixed to the embankment, and the drainage mechanism is also fixed to the embankment, and then evenly distributed hollow bricks are laid on the fixed support mechanism. The fixed support mechanism fixes the fence net and supports the hollow bricks at the same time. When it rains, the surface water on the road is discharged into the drainage ditch under the embankment along the drainage mechanism, and the rainwater on the embankment also seeps into the drainage mechanism and then is discharged into the drainage ditch, thereby further improving the stability of the embankment and further reducing the possibility of landslides on the embankment.

The reinforcement blocks are slidably connected to the fixed piles, and a resistance rod is slidably connected to the fixed piles, and the resistance rod corresponds to the reinforcement blocks.

[0012] By adopting the above technical solution, the abutment rod is inserted into the fixed pile, the abutment rod pushes the reinforcement block, and the reinforcement block extends from the fixed pile, thereby further improving the stability of the fixed pile inserted into the embankment.

[0013] Furthermore, a threaded ring is fixed on the limiting ring, and the threaded ring is threadedly connected to the interference rod.

[0014] By adopting the above technical solution, when the interference rod is inserted into the fixing pile, the interference rod is threadedly connected with the threaded ring, so that the interference rod can be stably inserted into the fixing pile.

[0015] Furthermore, the reinforcement block is provided with an inclined surface, and the inclined surface faces an end close to the nail head of the fixing pile.

[0016] By adopting the above technical solution, an inclined surface is provided on the reinforcement block, and when the fixed pile is inserted into the embankment, the reinforcement block is retracted into the fixed pile under the action of the inclined surface, thereby reducing the possibility that the reinforcement block affects the insertion of the fixed pile.

[0017] Furthermore, the drainage mechanism includes a water collecting square pipe fixed on a fixed baffle, and evenly distributed water collecting holes are provided on a side of the water collecting square pipe away from the fixed baffle and a side of the water collecting square pipe away from the embankment. A through hole is provided on the fixed baffle, and the through hole is connected to the water collecting square pipe.

[0018] By adopting the above technical solution, the water collecting square pipe can collect the accumulated water on the road surface, and then discharge it layer by layer to the drainage channel, so that the accumulated water on the road surface can be collected conveniently.

[0019] Furthermore, a communication pipe is provided between adjacent fixed baffles, one end of the communication pipe conflicts with the fixed baffle and corresponds to the through hole, and the other end of the communication pipe conflicts with the water collecting square pipe.

[0020] By adopting the above technical solution, the accumulated water in the water collecting square pipe can pass through the connecting pipe, then be drained layer by layer, and finally flow to the drainage ditch, so that the collected accumulated water can be easily entered into the drainage ditch.

[0033] The embodiment of this application discloses a retaining and protecting structure for steep embankments.

[0034] Referring to Figure 1 、 Figure 2 and Figure 3 , a retaining and protecting structure for a steep embankment 1 includes an embankment 1, a road surface 2 is arranged on the embankment 1, a drainage channel 3 is arranged below the embankment 1, a fence net 7 is laid on the embankment 1, uniformly distributed hollow bricks 4 are laid on the fence net 7, a fixed support mechanism 5 is arranged on the embankment 1, and a drainage mechanism 6 is arranged on the embankment 1. When retaining and protecting the embankment 1, first lay the fence net 7 on the slope of the embankment 1 to make the fence net 7 closely adhere to the slope of the embankment 1, then fix the fixed support mechanism 5 to the embankment 1, and at the same time fix the drainage mechanism 6 to the embankment 1. Then lay uniformly distributed hollow bricks 4 on the fixed support mechanism 5. The fixed support mechanism 5 fixes the fence net 7 and supports the hollow bricks 4. When it rains, the water accumulated on the road surface 2 drains into the drainage channel 3 below the embankment 1 along the drainage mechanism 6, and the rainwater on the embankment 1 also seeps into the drainage mechanism 6 and then drains into the drainage channel 3. By using the fixed support mechanism 5 to segmentally support the fence net 7 and the hollow bricks 4, the stability of the embankment 1 can be further improved, and the possibility of the embankment 1 landsliding can be further reduced.

[0035] Referring to Figure 1 、 Figure 2 and Figure 3The fixed support mechanism 5 includes a plurality of fixed baffles 51 uniformly distributed laterally, a plurality of fixed piles 52 are arranged on the fixed baffles 51, the fixed piles 52 penetrate the fixed baffles 51, a limiting ring 53 is fixed at one end of the fixed baffles 51, the limiting ring 53 conflicts with the fixed baffles 51, and a reinforcement component 54 is arranged on the fixed piles 52.

[0036] In addition, the reinforcement assembly 54 includes a plurality of reinforcement blocks 541 arranged on the fixed pile 52, and the plurality of reinforcement blocks 541 are located at one end of the fixed pile 52 away from the fixed baffle 51. The reinforcement blocks 541 are slidably connected to the fixed pile 52, and a resistance rod 542 is slidably connected to the fixed pile 52, and the resistance rod 542 corresponds to the reinforcement block 541.

[0037] Moreover, a threaded ring 543 is fixed on the limiting ring 53 , and the threaded ring 543 is threadedly connected to the abutment rod 542 .

[0038] Furthermore, a slope is formed on the reinforcing block 541 , and the slope faces the end close to the nail head of the fixing pile 52 .

[0039] After laying the fence net 7 on the embankment 1, the fixed stop bar 51 is placed on the fence net 7 and abuts against the fence net 7, and then the fixed pile 52 passes through the fixed stop bar 51 and is inserted into the ground of the embankment 1, so that the limiting ring 53 on the fixed pile 52 abuts against the fixed stop bar 51, and the fixed pile 52 and the limiting ring 53 restrict and fix the fixed stop bar 51, and then the abutment rod 542 is inserted into the fixed pile 52, and the abutment rod 542 is threadedly connected with the threaded ring 543, and the abutment rod 542 is moved into the fixed pile 52, and then the abutment rod 542 is inserted into the fixed pile 52.
