[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Reference Figure 1 and Figure 2 The utility model discloses a slope cutting structure, which comprises a structural bottom plate 1, a pile-sheet wall 2 and a second retaining wall 4.

[0024] The structural base plate 1 is a reinforced concrete structure, and a plurality of groups of anti-sliding piles 10 are arranged at the bottom thereof to prevent the structural base plate 1 from being displaced due to the water and soil pressure of the broken rock and soil of the slope.

[0025] In addition, drainage ditches 11 are arranged on both sides of the structural bottom plate 1 , and cover plates are arranged on the ditches 11 .

[0026] In the road cutting structure, the retaining wall close to the side of the slope directly bears the water and soil pressure generated by the broken rock and soil of the slope. Therefore, the retaining wall on this side adopts a pile-sheet wall 2.

[0027] Reference Figure 2The pile-sheet wall 2 includes a plurality of piles 25 arranged linearly, and each two adjacent groups of piles 25 are connected by a first retaining wall 20, so that the pile-sheet wall 2 itself has high structural strength and is not easily tilted or deformed due to water and soil pressure.

[0028] In addition, refer to Figure 1 The second retaining wall 4 is arranged on the other side of the structural base plate 1 relative to the pile-sheet wall 2. According to the slope terrain, the water and soil pressure on the second retaining wall 4 is much lower than the water and soil pressure on the pile-sheet wall 2, and the height of the second retaining wall 4 is lower than the first retaining wall 20.

[0029] Reference Figure 1 The first retaining wall 20 and the second retaining wall 4 are arranged opposite to each other, and a permeable layer 22 is arranged on the back of the opposite surfaces of the two. The permeable layer 22 is mainly used to quickly discharge the accumulated water in the crushed rock. Therefore, the permeable layer 22 adopts a structure of pebbles and gravel filled in the pebbles.

[0030] Among them, refer to Figure 2 The permeable layer 22 on the back of the first retaining wall 20 is arranged in the gap between each two adjacent groups of piles 25 .

[0031] In the above embodiment, the water-permeable layer 22 is connected to the ditches 11 on both sides of the structural bottom plate 1 through a plurality of drainage pipes 30 penetrating the first retaining wall 20 and the second retaining wall 4 , so that the accumulated water can be easily drained into the ditches 11 .

[0032] In one embodiment, a permeable pipe 3 is buried in the permeable layer 22 , and the permeable pipe 3 is connected to a plurality of drainage pipes 30 . A plurality of permeable holes are provided on the side wall of the permeable pipe, which can guide the accumulated water into the drainage pipe 30 while preventing gravel from entering the permeable pipe 3 .

[0033] In addition, in order to reduce the impact of rainfall on the upper side slope of the pile-sheet wall 2 , a drainage channel 23 is also provided on the upper side slope of the pile-sheet wall 2 .

[0034] In order to enhance the structural strength of the pile-sheet wall 2 and the second retaining wall 4 , in one embodiment, a plurality of buttresses 21 are further provided on the opposite surfaces of the first retaining wall 20 and the second retaining wall 4 .

[0035] During the construction process, anchor rods 24 are driven into the broken rock mass and grouted to combine the broken rock mass 24 into a whole and reduce the risk of collapse and deformation. During the casting of the pile-sheet wall 2, the part of the anchor rod 24 located outside the slope is cast in the first retaining wall 20.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
