Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, and in particular relates to a recyclable slope ecological protection structure and a construction method thereof. Background Art

[0002] In some construction projects, because the project is located in an urban area and the terrain is undulating, the original design requires a certain amount of excavation during the construction process to expand the effective use space of the relevant buildings. The narrow original area will result in some steep and high slopes during the excavation process. Due to the effective space, the slope cannot be effectively eliminated and can only maintain the existing slope shape.

[0003] In view of the above situation, the traditional protection and support measures adopt concrete spraying anchor, mortar masonry, and green grass vegetation on the slope. The support of the slope has a certain stability, but there are also certain defects: first, the protective layer is only a thin layer, which is easy to be damaged by external objects and the sealing is reduced after repair, which is easy to cause water erosion; second, after the surface hardens, natural water bodies such as rainwater cannot erode the slope, but the problem is that the rapid loss of water bodies cannot achieve effective soil and water conservation and the concept of green construction. In addition, after a one-time construction, if there are design changes, house demolition, road rights expansion, etc., it cannot be used again and can only be destroyed and become construction waste; there are green plants that need protection and stability, and most of them can only be planted with grass, which is single and cannot effectively guarantee the aesthetics; the one-time use characteristics and the inability to recycle violate the concept of energy conservation, emission reduction, and green construction.

[0004] It can be seen that the above-mentioned methods can provide protection for the stability of the slope to a certain extent, but there are many unfavorable factors such as low soil and water conservation efficiency, one-time projects cannot be recycled, poor repair effect once damaged, steep slopes and high flow rates of rainwater, which can easily cause splashing, long-term water flow causing serious erosion on the toe of the slope, and poor aesthetics, which also have a certain impact on the overall appearance of the building construction project. Summary of the invention

[0005] The purpose of the present invention is to provide a recyclable slope ecological protection structure and a construction method thereof, so as to solve the problems existing in the prior art such as low soil and water conservation efficiency, inability to recycle one-time projects, poor repair effect once damaged, high flow rate of rainwater on steep slopes and easy splashing, serious erosion of the slope foot by long-term water flow, poor aesthetics, and certain influence on the overall aesthetics of building construction projects, so that the structure can be beneficial to soil and water conservation on the slope, can be recycled, is easy to repair, has good impact resistance, is beneficial to slope stability, and has beautiful planting.

The holes can be filled with soil for planting. The slope soil body is covered by the geotextile and the masonry, and the soil and water conservation function can be improved by filling the holes with soil and planting green plants. The building blocks, the anchor rods, and the geotextile can be recycled to avoid one-time losses and save energy and reduce emissions.

[0024] The slope ecological protection structure and the construction method thereof provided by the present invention have the following beneficial effects:

[0025] 1. The recyclable slope ecological protection structure and the construction method thereof provided by the present invention, on the basis of isolating the direct contact between the slope and the water body, retain some indirect contact channels, mainly in the following ways: the slope ecological protection structure is a masonry with a cylindrical hole in the center that is cast at one time, and then the masonry is stacked in a stepped manner and connected to each other according to the actual slope of the slope on site, thereby providing a guarantee for the stability of the slope through the stability of its own weight and the connection between them; the thickness of the slope protection structure and the protection against gravity impact of external objects are increased by the thickness of the masonry itself, thereby effectively reducing the possibility of damage to the slope protection structure and avoiding the risks of reduced sealing and mismatch caused by subsequent damage repairs; the flow rate of the surface water body is effectively reduced by its own stepped stacking, thereby further increasing soil and water protection while reducing the flow rate of water when it reaches the toe of the slope, thereby reducing the problems of water erosion and splashing at the toe of the slope.

[0026] 2. The recyclable slope ecological protection structure and construction method provided by the present invention can adopt the method of one-time concrete pouring of blocks, and realize the recycling of engineering materials, the beautification of diversified planting and recycling by means of geotextile backing, stepped stacking of blocks, center holes of blocks, and diversified planting in the gaps between blocks, thereby further achieving the effects of energy conservation, emission reduction and green construction.

[0027] 3. The recyclable slope ecological protection structure and its construction method provided by the present invention provide an ecological protection structure for high and steep slopes that can be used for soil and water conservation, recycling and planting beautiful plants in various construction processes such as house construction and highway engineering construction; provide a way of recycling the main materials for slope protection operations in traditional narrow spaces, realize the call for energy conservation and emission reduction, and reduce long-term costs; reduce the probability of slope instability caused by soil erosion and slope foot erosion; facilitate the realization of diversified planting, effectively improve the unsightly appearance of slopes and steepness, and better meet the needs of appearance matching within a limited range; the required materials are all existing materials on the construction site, and the requirements for raw materials are relatively high Low, masonry structure is mainly based on the requirements of self-weight stability, and does not have excessive requirements on its own bearing capacity and strength; the masonry blocks are simple in shape without complex shapes, and the molds can be made on site with low cost; increasing the thickness of the masonry blocks can increase the impact resistance and anti-destruction performance of the protective structure; they can be disassembled and used in a cycle as the construction site changes, which increases practicality and reduces loss, saves costs from an economic perspective, and reduces material loss from an environmental perspective; the self-weight of the blocks can be adjusted to be large enough according to actual conditions, the blocks are interconnected, and the installation and stacking are simple, the blocks are quickly built and installed at one time, the unified mold for the blocks has high production efficiency, and the standardized shape of the blocks is easy to transport, which makes them highly operational and safe, and reduces safety costs.

[0028] 4. The recyclable slope ecological protection structure and construction method provided by the present invention can solve many unfavorable factors existing in the prior art, such as low soil and water conservation efficiency, inability to recycle one-time projects, poor repair effect once damaged, steep slopes and high rainwater collection flow rate that easily causes splashing, long-term water flow causing serious erosion of the slope foot, poor aesthetics, and a certain impact on the overall aesthetics of the building construction project. It can reduce the flow rate of water on the slope, which is beneficial to soil and water conservation and stability of the slope, is easy to disassemble, has good impact resistance, is easy to repair, can be recycled, saves energy and reduces emissions, and is also beautiful. Since the stacking area area of ​​the upper and lower layers of blocks to form steps can be adjusted according to different space sizes, the slope range that can be applied to slope protection is relatively large, and it is particularly suitable for the protection construction of higher and steeper slopes where the construction space is limited and the slope cannot be effectively lowered.

[0038] The present invention is further described in detail below through the accompanying drawings and specific embodiments.

[0039] Embodiment 1

[0040] Please refer to Figures 1 to 6 The present embodiment provides a recyclable slope ecological protection structure, including a slope soil 1, a geotextile 2 and a building block 3, wherein the geotextile 2 is covered on the slope surface of the slope soil 1; the building block 3 is provided with a hole 301 and at least two reserved holes, and anchor rods 302 are arranged in the reserved holes; the building blocks 3 are arranged in at least two layers from bottom to top, and the number of building blocks 3 in each layer is set to at least two, and two adjacent building blocks 3 in each layer of building blocks 3 are contacted and spliced; the multiple layers of building blocks 3 are stacked and connected upward and backward in a stepped shape, and each building block 3 is connected to the geotextile 2 and the slope soil 1 by at least one anchor rod 302; two adjacent layers of building blocks 3 corresponding to each other, the geotextile 2 and the slope soil 1 are connected by at least one anchor rod 302, and the hole 301 is arranged outside the stacking area of ​​the building blocks 3.

[0041] The front and rear directions refer to Figure 5 The downward and upward directions shown in also refer to Figure 6 The right and left directions shown in .

[0042] like Figures 4 to 6 As shown, specifically, the slope surface of the slope soil body 1 is set as at least two layers of stepped surfaces inclined upward and backward, the geotextile 2 is laid on each layer of the stepped surface, and the multi-layer building blocks 3 are stacked and connected to the side and top surfaces of each layer of the stepped surface from bottom to top. The stepped layout reduces the flow rate of the water body on the slope surface of the slope soil body 1, further maintains water and soil, and prevents the high-speed falling water flow from eroding the slope foot.

[0043] like Figure 6 As shown, specifically, the geotextile 2 is configured as a single layer.

[0044] like Figure 2 and Figure 5 As shown, specifically, the hole 301 is opened at the center of the building block 3, and the hole 301 is set to be circular.

[0045] like Figure 6 As shown, specifically, reserved holes are respectively provided on the front and rear sides of the hole 301 .

[0046] like Figure 2 and Figure 5 As shown, specifically, the building blocks 3 are arranged as regular hexagonal columns.

[0047] like Figure 5 As shown, specifically, the holes 301, the gaps between two adjacent blocks 3 in each layer of blocks 3, and the gaps between two corresponding blocks 3 in two adjacent layers of blocks 3 are filled with soil 4. A structure similar to a flower bed is formed in the gaps and holes 301 of the stacked structure, and various types of planting can be carried out to meet the needs of aesthetic layout and water and soil conservation.

[0048] Specifically, two adjacent building blocks 3 in the same layer of building blocks 3 are contacted and spliced ​​at adjacent vertex positions, that is, in each layer of building blocks 3, adjacent vertex positions of two adjacent building blocks 3 are in close contact, which is conducive to having sufficient gaps between two adjacent building blocks 3 in the same layer for filling with soil 4, and is also conducive to the front and rear sides of the building blocks 3 in each layer being parallel to or aligned with the vertical sides of the steps, respectively, thereby improving the neatness, aesthetics and stability of each layer of building blocks 3 after being stacked on each level of steps.

[0049] Please refer to Figures 1 to 6, it can also be specific that the hole 302, the reserved hole and the anchor rod 302 are all set to be vertical. The block 3 is set to be a concrete block cast in one time. The hole 301 is set to be a cylindrical hole. The inner diameter of the reserved hole is equal to the diameter of the anchor rod 302, and the diameter of the anchor rod 302 is set to 1 cm. The step surface is set to be rectangular. The diameter of the hole 301 is set to 15 cm. The side length of the block 3 is set to 40 cm. The stacking size of the upper and lower layers of adjacent blocks 3 in the front and rear direction is set to 15 cm, that is, the stacking size of the upper and lower layers of blocks 3 is 15 cm, and they are stacked upward and backward layer by layer. The thickness of the block 3 is set to 50 cm. The length of the anchor rod 302 is the thickness of the upper and lower layers of blocks 302 plus the depth of the anchor rod 302 into the soil. For example, if the depth of the anchor rod 302 into the soil is 10 cm, the length of the anchor rod 302 is 110 cm, thereby ensuring the stability of the upper and lower layers of blocks 302, the geotextile 2 and the slope soil 1 connected by the anchor rod 302. The width of the step surface is 55 cm and the height is 30 cm. The spacing between adjacent holes 301 and the density of the reserved holes can be set according to the slope of the slope soil 1.

[0050] like Figures 4 to 6 As shown, the upper and lower layers of blocks 3 can be arranged in a staggered manner. That is, the front side of the blocks 3 of the upper layer is placed on the adjacent rear corner positions of the two blocks 3 of the lower layer, thereby improving the firmness and stability of the stacking structure of the upper and lower layers of blocks 3 and facilitating the filling of soil in the gaps between the upper and lower layers of blocks 3. The two front corner positions and the two rear corner positions of the blocks 3 can be provided with reserved holes, and anchor rods 302 can be respectively arranged in the reserved holes. The two front corner positions of each layer of blocks 3 at the middle position can be respectively connected to the adjacent rear corner positions of the two adjacent blocks 3 of the lower layer through the anchor rods 302, and the two rear corner positions of each layer of blocks 3 at the middle position can be respectively connected to the adjacent front corner positions of the two adjacent blocks 3 of the upper layer through the anchor rods 302; stacking layers by layers in this way makes the multi-layer blocks 3 form a firm and stable protective structure.
