[0031] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.
[0032] Combination Figures 1 to 4 As shown, this embodiment is a undisturbed soil step structure, including an undisturbed soil step body 1 and a wood-look crossbar 2. The undisturbed soil step body 1 is prefabricated from the undisturbed soil at the construction site, and the slope surface is compacted with plain soil 11 to form a foundation. The front edge of the tread of the undisturbed soil step body 1 is provided with a first protrusion 5, and the rear edge of the tread is provided with a locking groove 12. Multiple undisturbed soil step bodies 1 are arranged in multiple levels on the foundation of the slope surface. A wood-look crossbar 2 is provided between two adjacent levels of undisturbed soil step bodies 1. The bottom of the wood-look crossbar 2 is engaged in the locking groove 12 on the next level of undisturbed soil step body 1, and the first protrusion 5 of the previous level of undisturbed soil step body 1 is engaged in the rectangular groove 13 of the wood-look crossbar 2 to complete the splicing between adjacent undisturbed soil step bodies 1. The surface of the wood-look crossbar 2 is provided with a second protrusion 10, which can abut against the top surface of the next level of undisturbed soil step body 1.
[0033] In some implementation schemes, such as Figure 1 and Figure 4 As shown, the imitation wood crossbar 2 is made of reinforced concrete. The imitation wood crossbar 2 has a reinforcement structure inside, which includes a first reinforcement 7 and a second reinforcement 8. Multiple first reinforcement 7 are arranged horizontally inside the imitation wood crossbar 2 and spaced apart along the inclined vertical direction. Multiple second reinforcement 8 are arranged horizontally inside the imitation wood crossbar 2 and spaced apart along the inclined vertical direction. The multiple first reinforcement 7 and multiple second reinforcement 8 are staggered and connected to form a steel mesh.
[0034] Furthermore, the multiple first reinforcing bars 7 include at least three first reinforcing bars 7. In this embodiment, three first reinforcing bars 7 are used. The specific arrangement is as follows: the first first reinforcing bar 7 is located in the second protrusion 10 of the imitation wood crossbar 2, and the first first reinforcing bar 7 corresponds to the first protrusion 5 of the original soil step body 1. The second first reinforcing bar 7 is located at the middle position of the imitation wood crossbar 2 in the vertical direction. The third first reinforcing bar 7 is located at the bottom position of the imitation wood crossbar 2, and the third first reinforcing bar 7 corresponds to the snap-fit groove 12 of the original soil step body 1.
[0035] Furthermore, in this embodiment, the first reinforcement 7 is φ10 and the second reinforcement 8 is φ8@150.
[0036] Furthermore, the surface of the wood-look crossbar 2 is coated with a wood-look paint finish 9.
[0037] In some embodiments, the second protrusion 10 has a multi-layered semi-cylindrical structure.
[0038] In terms of structural stability, the second protrusion 10, with its multi-layered semi-cylindrical structure, provides vertical support. The contact between the second protrusion 10 and the next step creates an additional support point, helping to distribute vertical loads and reduce the risk of excessive stress at a single point, thus improving the overall stability and load-bearing capacity of the structure. The second protrusion 10 also provides horizontal restraint. When pedestrians ascend or descend the steps, they may exert a certain horizontal thrust on the steps. The presence of the second protrusion 10 can, to some extent, limit this horizontal displacement, ensuring that adjacent steps do not easily slip relative to each other, thus enhancing the tightness of the connection. In terms of decorative effect, this design not only adds an artistic touch to the staircase structure but also makes it more harmonious with the natural environment, enhancing its overall aesthetic value.
[0039] In some implementation schemes, such as Figure 2 and Figure 3 As shown, a drainage ditch 3 is provided on the slope surface of any end of the undisturbed soil step body 1. The tread surface of the undisturbed soil step body 1 has a certain slope, so that water on the tread surface of the undisturbed soil step body 1 can naturally flow into the drainage ditch 3. Specifically, in this embodiment, the slope 4 of the tread surface of the undisturbed soil step body 1 is not less than 2%.
[0040] By setting the drainage ditch 3 at an appropriate slope to the original soil step body 1, the step structure can be ensured to have good drainage performance, reducing the possibility of water accumulation on the step surface and protecting the step body from long-term rainwater erosion.
[0041] In some implementation schemes, in this embodiment, the specific dimensions of the step structure are as follows: the height of the bottom undisturbed soil step body 1 is 180mm, the height of the remaining undisturbed soil step bodies 1 is 150mm, the step width of the undisturbed soil step body 1 is greater than or equal to 240mm, the width of the snap-fit groove 12 is 80mm, the depth of the snap-fit groove 12 is 100mm, the width of the rectangular groove 13 is 60mm, the width of the first protrusion 5 is 60mm, and the width of the second protrusion 10 is 60mm.
[0042] The implementation principle of the undisturbed soil step structure in this embodiment is as follows:
[0043] In this application, the original soil steps 1 are prefabricated using the existing undisturbed soil on site, which reduces the introduction of a large amount of external materials, simplifies the construction process, and improves construction efficiency. The use of locally sourced materials also reduces environmental impact and preserves the original ecosystem.
[0044] The original soil step body 1 and the imitation wood crossbar 2 are connected by a snap-fit structure, which improves construction efficiency. At the same time, in this application, the surface of the imitation wood crossbar 2 abuts against the next level of original soil step body 1 through the second protrusion 10. This structural design increases the contact area between the imitation wood crossbar 2 and the next level of original soil step body 1, making the load distribution more uniform and reducing local stress concentration.
[0045] The imitation wood crossbar 2 is constructed of reinforced concrete with internal reinforcement, enhancing its overall rigidity and bending resistance. This results in high strength and durability, enabling it to withstand long-term external loads without easily being damaged, thus extending its service life. The surface of the imitation wood crossbar 2 is coated with imitation wood grain paint finish 9, mimicking the appearance of natural wood while providing excellent corrosion resistance.
[0046] In mountainous environments, compared to using stone to construct step structures, the use of undisturbed earth steps in this application can reduce material transportation costs and minimize the impact on the ecology. Moreover, the appearance design of the imitation wood crossbar 2 makes it more harmonious with the natural environment and increases the aesthetic value of the step structure.
[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
