Description

Technical Field

[0001] The present invention relates to the field of slope management, and in particular to a green ecological slope management structure and a construction method thereof. Background Art

[0002] Green ecological slopes are a slope protection system built through a combination of natural and engineering approaches, with ecological restoration at its core. Its core concept is to restore damaged ecosystems using vegetation, natural materials, and ecological engineering techniques while ensuring the stability of the slope structure, thereby achieving the synergistic benefits of soil and water conservation, landscaping, and biodiversity protection.

[0003] At present, the commonly used green ecological slopes mainly include: cast-in-place green concrete slope protection, imported soil spraying technology slope protection, three-dimensional vegetation net slope protection, vegetation concrete technology slope protection, ecological bag slope protection, etc. However, the support effect of the above technologies is poor, such as insufficient support structure strength, anchor failure, uneven spraying thickness, lack of drainage facilities, etc., which lead to failure of the slope protection structure or matrix shedding. The selection of vegetation and the slope gradient lead to the failure of slope support, the vegetation is washed away by water, and secondary soil and water loss occurs on the slope. Based on this, the present invention proposes a green ecological slope management structure and its construction method. Summary of the Invention

[0004] In response to the above-mentioned technical problems existing in the prior art, the present invention proposes a green ecological slope management structure and its construction method, which overcomes the shortcomings of the prior art. By adopting a stepped design to break the slope into small pieces, and the slope surface is supported by a plate-like structure composed of a slope protection structure, a crown beam, anchor rods, and a stiffener, the overall support effect is good, which can fully mobilize the role of the deep soil and solve the problem of poor slope stability; by setting up a green ecological platform, the survival rate of vegetation is guaranteed, and it is easier to carry out landscape design, solving the problem of traditional slope planting causing vegetation to be washed away by water and having a low survival rate; climbing plants are planted at the foot of the slope protection structure and the green ecological platform. The climbing plants are attached to the surface of the slope protection structure, which increases the overall greening effect.

[0005] A green ecological slope management structure includes a slope protection structure, a green ecological platform, a crown beam, anchor rods, and a stiffener. The entire original slope is divided into steps by the slope protection structure and the green ecological platform.

The slope protection structure, the crown beam, the anchor rods, and the stiffener together form a plate-like structure. Green plants are planted on the green ecological platform and drainage ditches are provided.

[0006] Preferably, the angle between the slope protection structure and the vertical plane is 0°-45°, and the slope protection structure is an interlocking mixing pile or a TRD mixing wall.

[0010] A construction method for a green ecological slope control structure is provided, wherein construction equipment is used to construct the green ecological slope control structure. The specific construction method is as follows: Step 1: Construction of slope protection structure Use inclined pile mixing equipment or TRD equipment for construction. During the construction process, inject cement slurry or curing agent slurry and mix it evenly with the in-situ soil. Determine the angle between the slope protection structure and the vertical surface according to the design. When using inclined pile mixing equipment, control the interlocking distance of the mixing piles; when using TRD equipment, directly form a trough structure. Step 2: Implant the stiffener Implant the stiffener into the completed slope protection structure before the initial setting of the slope protection structure. Determine whether the stiffener is a continuous structure or a discontinuous structure based on the depth of the slope protection structure. When the stiffener is a continuous structure, steel mesh and steel sheet piles are preferred. When the stiffener is a discontinuous structure, steel pipes, precast piles, steel mesh and steel sheet piles are selected. Step 3: Casting the crown beam When the slope protection structure reaches the designed strength, the top of the slope protection structure is trimmed to expose the stiffener, and the formwork is supported to cast the concrete crown beam, ensuring that the steel bars in the crown beam are connected to the stiffener; Step 4: Excavate and install anchor bolts in steps Excavate the original slope along the slope protection structure, excavating downward in steps. When the excavation reaches the designed depth of the anchor bolt, stop excavation and install the anchor bolt. After the anchor bolt is completed, continue the next step of excavation until the first step-like structure is completed.

[0023] A construction method for a green ecological slope control structure is provided, wherein construction equipment is used to construct the green ecological slope control structure. The specific construction method is as follows: Step 1: Construction of slope protection structure 1 Use inclined pile mixing equipment or TRD equipment for construction. During the construction process, inject cement slurry or curing agent slurry and mix it evenly with the in-situ soil.

Step 2: Implant the stiffener 5 Implant the stiffener 5 in the completed slope protection structure 1 before the initial setting of the slope protection structure 1. Determine whether the stiffener 5 is a continuous structure or a discontinuous structure according to the depth of the slope protection structure 1. When the stiffener 5 is a continuous structure, steel mesh and steel sheet piles are preferably used. When the stiffener 5 is a discontinuous structure, steel pipes, precast piles, steel mesh and steel sheet piles are selected. Step 3: Casting crown beam 3 When the slope protection structure 1 reaches the designed strength, the top of the slope protection structure 1 is trimmed to expose the stiffener 5, and the formwork is supported to cast the concrete crown beam 3, ensuring that the steel bars in the crown beam 3 are connected to the stiffener 5; Step 4: Excavate and install anchor bolts in steps 4 Excavate the original slope along the slope protection structure 1, and excavate downward in steps.

[0025] Preferably, the TRD device is provided with a rotary structure on the upper portion of the chain-type cutting tool, and the rotary structure drives the chain-type cutting tool to rotate clockwise or counterclockwise. Example 2:

[0026] like Figures 1-3 As shown, a green ecological slope management structure includes a slope protection structure 1, a green ecological platform 2, a crown beam 3, an anchor rod 4, and a stiffener 5. The entire original slope is divided into steps by the slope protection structure 1 and the green ecological platform 2. The step-shaped setting is to increase the overall stability of the slope. The stiffener 5 is set in the slope protection structure 1, and the top of the slope protection structure 1 is provided with a crown beam 3. The stiffener 5 is connected to the crown beam 3. The bottom of the slope protection structure 1 is inserted into the lower green ecological platform 2. The slope protection structure 1 part with the stiffener 5 is provided. Anchor rods 4 are provided, and the slope protection structure 1, crown beam 3, anchor rods 4, and stiffeners 5 together form a plate-like structure. The slope protection structure 1 is actually already an integral plate-like structure. In order to further increase the strength of the plate-like structure, stiffeners 5 are inserted into the interior of the slope protection structure 1, and no crown beam 3 is provided on it. The crown beam 3 connects the stiffeners 5 into a whole, and the anchor rods 4 on the surface of the slope protection structure 1 can connect the slope protection structure 1 with the deep soil, further ensuring the structural strength. Green plants are planted on the green ecological platform 2 and drainage ditches are set.

[0027] Preferably, the slope protection structure 1 is angled between 0° and 45° with the vertical, and is constructed using interlocking mixing piles or a TRD mixing wall. While the slope protection structure 1 can be constructed using mixing piles or other equipment, TRD equipment is the most suitable, as it allows the wall to be formed in one go, ensuring integrity. Furthermore, the angle between the slope protection structure 1 and the vertical is intended to reduce the static earth pressure on the slope protection structure 1.

[0028] Preferably, the types of the stiffeners 5 include steel pipes, steel meshes, prefabricated piles, and steel sheet piles, and the stiffeners 5 are arranged in an intermittent or continuous manner.

[0029] Preferably, the anchor rods 4 are installed at the part of the slope protection structure 1 provided with the stiffener 5, and the number of rows and length of the anchor rods 4 are calculated and determined according to the actual conditions of the slope. The anchor rods 4 are calculated and set according to various parameters such as the slope gradient, the depth of a step, and the overall depth.

[0030] Preferably, the length of the bottom of the slope protection structure 1 inserted into the lower green ecological platform 2 is calculated and determined according to the actual situation of the slope. The bottom of the slope protection structure 1 is inserted into the lower green ecological platform 2 to increase the stability of the slope protection structure 1, which is equivalent to the role of the anchoring section.

[0031] A construction method for a green ecological slope control structure is provided, wherein construction equipment is used to construct the green ecological slope control structure. The specific construction method is as follows: Step 1: Construction of slope protection structure 1 Use inclined pile mixing equipment or TRD equipment for construction. During the construction process, inject cement slurry or curing agent slurry and mix it evenly with the in-situ soil. Determine the angle between the slope protection structure 1 and the vertical plane according to the design. When using inclined pile mixing equipment, control the engagement distance of the mixing piles; when using TRD equipment, directly form a trough structure. Step 2: Implant the stiffener 5 Implant the stiffener 5 in the completed slope protection structure 1 before the initial setting of the slope protection structure 1. Determine whether the stiffener 5 is a continuous structure or a discontinuous structure according to the depth of the slope protection structure 1. When the stiffener 5 is a continuous structure, steel mesh and steel sheet piles are preferably used. When the stiffener 5 is a discontinuous structure, steel pipes, precast piles, steel mesh and steel sheet piles are selected. Step 3: Casting crown beam 3 When the slope protection structure 1 reaches the designed strength, the top of the slope protection structure 1 is trimmed to expose the stiffener 5, and the formwork is supported to cast the concrete crown beam 3, ensuring that the steel bars in the crown beam 3 are connected to the stiffener 5; Step 4: Excavate and install anchor bolts in steps 4 Excavate the original slope along the slope protection structure 1, and excavate downward in steps. When the excavation reaches the designed depth of the anchor rod 4, stop excavation and construct the anchor rod 4. After the construction of the anchor rod 4 is completed, continue the next step of excavation until the first step-like structure is completed. Repeat the steps until step 4 until the entire slope is trimmed into a step-like structure; Step 5: Slope protection and treatment Drain holes are installed on the surface of slope protection structure 1, while drainage ditches are installed on the surface of green ecological platform 2. Green plants are planted on the surface of green ecological platform 2 to complete the slope management. The establishment of green ecological platform 2 ensures the survival rate of vegetation and facilitates landscape design, solving the problem of traditional slope planting, which often causes vegetation to be washed away by water and has a low survival rate.

[0032] Preferably, green plants are planted on the surface of the green ecological platform 2, including trees, shrubs and lawns, and climbing plants are planted at the foot of the slope protection structure 1 and the green ecological platform 2, and the climbing plants are attached to the surface of the slope protection structure 1. Planting climbing plants at the foot of the slope protection structure 1 and the green ecological platform 2, and the climbing plants are attached to the surface of the slope protection structure 1, increases the overall greening effect.

[0033] Preferably, the TRD device is provided with a rotary structure on the upper portion of the chain-type cutting tool, and the rotary structure drives the chain-type cutting tool to rotate clockwise or counterclockwise.
