Description

Technical Field

[0001] This utility model relates to the field of water conservancy, specifically to a structurally stable ecological open channel. Background Technology

[0002] An ecological open channel is a waterway system designed and constructed using natural materials and environmental characteristics, with the aim of reducing negative impacts on the environment, improving water quality, and protecting the ecological environment.

[0003] An ecological open channel includes the channel bottom and the slopes on both sides. Stones are placed on the slopes to stabilize them and prevent erosion by water flow. Compared to traditional protective structures (such as concrete walls), stones have better permeability, allowing water to seep through the gaps between the stones, reducing water pressure and facilitating natural flow and drainage. Furthermore, the stone design not only provides protection but also blends into the surrounding environment, creating a more natural landscape. The stones on the slopes of the ecological open channel also help maintain a suitable environment for aquatic plants, enhancing biodiversity.

[0004] However, the stones are located on a slope with a certain inclination, and the stones are not fixed by any structure. The stones are not very stable on the slope. When many stones are placed on the slope, the stones above press down on the stones below, and the stones above exert pressure on the stones below. There is a risk that the stones will slide down and collapse.

[0005] At the same time, during the rise and fall of the water flow, or under the impact of the water flow, the stones may also slide down or collapse.

[0006] Therefore, how to improve the stability of rocks on a slope is the technical problem that this application needs to solve. Utility Model Content

[0007] The present invention aims to provide a structurally stable ecological open channel to improve the stability of stones on the slope and reduce the slippage of stones.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a structurally stable ecological open channel, including a channel bottom and slopes located on both sides of the channel bottom, a stone partition fixedly provided on the slope, a plurality of placement holes provided on the stone partition, slope stones placed on the slope, and the slope stones filling the placement holes.

[0009] The principle and advantages of this scheme are as follows: This scheme fixes a stone separator on the slope, and the stone separator has multiple placement holes. The slope stones are placed in the placement holes, and the placement holes accommodate the slope stones. In this way, the slope stones in different placement holes are separated. The slope stones are laid on the slope, and the pressure of the slope stones presses on the inner wall of the placement holes, thereby reducing the downward pressure of the slope stones above on the slope stones below. This can prevent the slope stones below from sliding down due to the downward pressure of the slope stones above, and improve the stability of the slope stones on the slope.

[0010] In addition, the slope stones are located in the placement holes, which limit the slope stones and thus hinder their downward sliding, thereby reducing the sliding of slope stones and improving the stability of the slope stones.

[0011] Therefore, this solution utilizes stone separators to improve the stability of the stones on the slope by limiting the stones on the slope and preventing them from sliding down, and by reducing the pressure of the stones on the upper slope on the lower slope, thus reducing the downward sliding of the stones on the lower slope.

[0012] In this design, the slope stones are laid on the slope surface, stabilizing it and preventing erosion. The stones also have good permeability, allowing water to seep through the gaps between them. The perforated design ensures that the spacing between the stones does not obstruct water infiltration into the slope, facilitating natural water flow and drainage. Furthermore, the slope stones blend seamlessly with the surrounding environment, providing a more natural landscape effect. They also help maintain a suitable environment for aquatic plants, enhancing biodiversity.

[0013] In summary, the stone separators in this design stabilize the stones on the slope without affecting their function and value.

[0014] Preferably, as an improvement, the placement hole is square or round. Thus, the placement hole can be set in different shapes.

[0015] Preferably, as an improvement, the wall thickness of the placement hole is 200-300mm. Therefore, setting the wall thickness of the placement hole within this range ensures that the sidewalls of the placement hole have a certain load-bearing capacity.

[0016] Preferably, as an improvement, the material of the stone partition is C25 concrete.

[0017] Preferably, as an improvement, settlement joints are provided every 10m on the stone partition, and the settlement joints are filled with asphalt-impregnated hemp fibers.

[0018] Therefore, the purpose of setting settlement joints on the stone partition is to cope with the structural deformation of the stone partition caused by soil settlement, temperature changes or water flow, and to ensure the stability of the stone partition structure.

[0019] Asphalt-impregnated hemp fibers can seal settlement joints. At the same time, asphalt-impregnated hemp fibers have good elasticity and toughness, which can effectively absorb and adapt to the minor settlement deformation of the stone separation part.

[0020] Preferably, as an improvement, a slope crushed stone cushion layer is laid on the slope surface, and slope stones are placed on the slope crushed stone cushion layer.

[0021] Therefore, laying a gravel cushion layer on the slope can enhance the structural stability of the slope and prevent soil sliding or collapse caused by rainwater erosion or gravity. The gravel on the slope cushion layer can effectively disperse the pressure of the rocks on the slope, reducing the load on the slope soil. At the same time, the gravel can effectively prevent water flow from directly eroding the soil on the slope, reducing the risk of soil erosion. In environments with heavy rain or high water flow, the gravel can act as a "buffer," slowing down the speed of water flow and reducing the probability of soil erosion.

[0022] Preferably, as an improvement, multiple anchors are fixedly installed at the connection points between the channel bottom and the slope, and the stone separators and the slope stones at the bottom of the slope abut against the anchors.

[0023] Therefore, anchors are installed on both the left and right sides of the channel bottom. The stone partition and the slope stones at the bottom of the slope are all abutted against the anchors. In this way, the anchors restrain the stone partition and the slope stones at the bottom of the slope, and support the bottom of the stone partition and the slope stones at the bottom of the slope. This can effectively prevent the bank from collapsing during the rise and fall of the water, and greatly improve the stability of the slope.

[0024] Preferably, as an improvement, the bottom of the canal is paved with a crushed stone cushion layer, and canal bottom stones are placed on the crushed stone cushion layer, with the canal bottom stones located between the two sides of the canal foot.

[0025] Therefore, the gravel cushion layer laid on the canal bottom reduces the erosion of the canal bottom by the water flow and improves the canal bottom's resistance to erosion. The stones laid on the canal bottom are located between the two sides of the anchorage. The pressure on the anchorage from the bottom of the stone partition and the slope stones at the bottom of the slope can be transferred to the stones on the bottom of the canal bottom. The stones on the bottom of the canal bottom disperse the pressure on the anchorage, making the anchorage more stable on both sides of the canal bottom.

[0026] Preferably, as an improvement, the cross-section of the anchor foot is a 1m*1m square.

[0027] Preferably, as an improvement, the anchor foot material is C25 plain concrete.

[0028] Preferably, as an improvement, there are multiple anchor feet, which are arranged along the length of the channel bottom, and adjacent anchor feet are connected by connecting blocks.

[0029] Therefore, during construction, the anchor feet are transported to the construction site without being connected, and each anchor foot can be installed independently on the channel bottom. After each anchor foot is installed, adjacent anchor feet are connected by connecting blocks. In this way, multiple anchor feet are connected as a whole, thereby improving the stability of the anchor feet. Even if some anchor feet are not fixed and stable on the channel bottom, they will not tilt or shift because they are connected to other anchor feet, allowing the anchor feet to provide stable support for the structure on the slope.

[0030] Preferably, as an improvement, the end of the foot is provided with a slot on both sides, and the connecting block includes a first connecting part and a second connecting part. The first connecting part is plate-shaped and the second connecting part is T-shaped. The first connecting part and the second connecting part are fixedly connected. After the first connecting part and the second connecting part are connected, they form an I-shaped connecting block. The connecting block is locked between two adjacent feet, and the end of the second connecting part and the first connecting part are respectively locked in the slots on both sides of the foot.

[0031] Therefore, when connecting adjacent feet using the connecting block, the first connecting part is placed in the slot on one side of the foot, the second connecting part is inserted into the gap between adjacent feet, and the end of the second connecting part is placed in the slot on the other side of the foot. Then, the first and second connecting parts are connected. Using the connecting block in this solution, the connecting block can fill the gap between adjacent feet and also hold the two feet together. The slot design prevents the connecting block from protruding excessively from the side of the foot.

[0032] Preferably, as an improvement, the first connecting part and the second connecting part are fixedly connected by bolts and nuts. Attached Figure Description

[0035] Figure 3 This is a schematic diagram of the connection between adjacent town feet in Example 2, viewed from above. Detailed Implementation

[0036] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: 1. Anchor foot; 2. Bottom stone; 3. Slope stone; 4. Bottom gravel cushion layer; 5. Stone separator; 6. Slope gravel cushion layer; 7. Placement hole; 8. Settlement joint; 9. Bottom of the canal; 10. Slope; 11. First connection part; 12. Second connection part; 13. Bolt; 14. Slot.

[0037] Example 1 The basics are as follows: Figures 1-2 As shown: A structurally stable ecological open channel includes a channel bottom 9 and slopes 10 located on both sides of the channel bottom 9. In this embodiment, the width of the channel bottom 9 is 10m, and the slope of the slope 10 is 1:1.75. The height of the top of the slope 10 is 2.5m.

[0038] In this embodiment, gravel is laid on the slope 10 to form a slope gravel cushion layer 6, and the thickness of the slope gravel cushion layer 6 is 20cm.

[0039] A stone partition 5 is fixedly installed on the slope 10, and multiple placement holes 7 are provided on the stone partition 5. The placement holes 7 are square or round. Figure 2 A complete placement hole 7 is square in shape, with a side length of 2m and a wall thickness of 200-300mm, specifically 250mm. The stone partition 5 is made of C25 concrete. Since the stone partition 5 cannot extend indefinitely, it needs to be designed according to the specific area of ​​the slope 10. Figure 2 The placement hole 7 on the edge of the stone partition 5 is an incomplete square shape.

[0040] Along the length of the open channel, settlement joints 8 are installed every 10 meters on the stone partition section 5. These settlement joints 8 are filled with asphalt-impregnated hemp fibers. The width of the settlement joints 8 is 2-3 cm. The settlement joints 8 divide the stone partition section 5 into multiple independent unit modules. Figure 3 As shown, Figure 3 The stone partition 5 is composed of two independent unit modules joined together. Each independent unit module includes a square frame, within which multiple square placement holes 7 are provided, with the sidewalls of the placement holes 7 intersecting each other. Figure 1 As shown, the stone separator 5 is placed on the slope gravel cushion layer 6, and the stone placement part is inserted downward into the slope gravel cushion layer 6.

[0041] Slope stones 3 are placed on the slope 10, and the slope stones 3 fill the placement holes 7.

[0042] Combination Figure 1As shown, anchors 1 are fixedly installed at the connection points of the channel bottom 9 and the slope 10. Multiple anchors 1 are distributed along the length of the channel bottom 9, and each anchor 1 has a 1m x 1m square cross-section. The anchors 1 are made of C25 plain concrete. The bottom of the stone separator 5 and the slope stones 3 at the bottom of the slope 10 abut against the anchors 1. The channel bottom 9 is paved with gravel to form a gravel cushion layer 4, which is 20cm thick. Ditch bottom stones 2, 30cm thick, are placed on the gravel cushion layer 4 between the two anchors 1. In this embodiment, the anchors 1 are inserted downwards below the ground level of the channel bottom 9.

[0043] In this embodiment, the stone separator 5 is placed on the slope 10. The stone separator 5 is provided with multiple placement holes 7. The slope stones 3 are placed in the placement holes 7, and the placement holes 7 accommodate the slope stones 3. In this way, the slope stones 3 in different placement holes 7 are separated. The slope stones 3 are laid on the slope 10. The pressure of the slope stones 3 presses on the inner wall of the placement holes 7, thereby reducing the downward pressure of the upper slope stones 3 on the lower slope stones 3. This can prevent the lower slope stones 3 from sliding down due to the downward pressure of the upper slope stones 3, and improve the stability of the slope stones 3 on the slope 10.

[0044] In addition, the slope stone 3 is located in the placement hole 7, which limits the slope stone 3 and thus hinders the slope stone 3 from sliding down, thereby reducing the sliding of the slope stone 3 and improving the stability of the slope stone 3 on the slope 10.

[0045] In addition, there are anchors 1 on both the left and right sides of the channel bottom 9. The stone partition 5 and the slope stones 3 at the bottom of the slope 10 are all abutted against the anchors 1. In this way, the anchors 1 restrain the stone partition 5 and the slope stones 3 at the bottom of the slope 10, and support the bottom of the stone partition 5 and the slope stones 3 at the bottom of the slope 10. This can effectively prevent the bank slope from collapsing during the rise and fall of the water, and greatly improve the stability of the slope.

[0046] The pressure from the bottom of the stone partition 5 and the slope stone 3 at the bottom of the slope 10 on the bottom of the stone foot 1 can be transmitted to the bottom stone 2. The bottom stone 2 disperses the pressure on the bottom stone 1, making the bottom stone 1 more stable on both sides of the bottom 9.

[0047] In addition, in this embodiment, slope surface 10 is provided with slope stones 3 and some gravel, and channel bottom 9 is provided with some channel bottom stones 2 and gravel. The provision of stones and gravel can improve the bed resistance and erosion resistance of slope surface 10 and channel bottom 9.

[0048] In summary, this embodiment improves the stability of the slope stones 3 on the slope 10 by setting up structures such as stone partitions 5, footings 1, and bottom stones 2, making them less prone to slippage and collapse.

[0049] Example 2 This embodiment is a further improvement and optimization based on Embodiment 1.

[0050] Combination Figure 3 As shown, a connecting block connects the ends of adjacent foot 1. Both sides of the end of foot 1 are provided with slots 14. The connecting block includes a first connecting part 11 and a second connecting part 12. The first connecting part 11 is plate-shaped, and the second connecting part 12 is T-shaped. Both the first connecting part 11 and the second connecting part 12 are provided with bolt holes. The first connecting part 11 and the second connecting part 12 are fixedly connected by bolts 13 and nuts, etc. After the first connecting part 11 and the second connecting part 12 are connected, they form an I-shaped connecting block. The connecting block is locked between two adjacent foot 1s. The end of the second connecting part 12 and the first connecting part 11 are respectively locked in the slots 14 on both sides of the foot 1.

[0051] Therefore, during construction, the anchor feet 1 are transported to the construction site. At this time, the anchor feet 1 are not connected, and each anchor foot 1 can be installed independently on the channel bottom 9. After each anchor foot 1 is installed in place, the ends of adjacent anchor feet 1 are connected by connecting blocks. During connection, the first connecting part 11 is placed in the slot 14 on the left side of the anchor foot 1. The first connecting part 11 is located in the slot 14 on the left side of the two adjacent anchor feet 1 with their ends close to each other. Then, the second connecting part 12 is inserted into the gap between the ends of adjacent anchor feet 1. The right end of the second connecting part 12 is placed in the slot 14 on the right side of the two adjacent anchor feet 1 with their ends close to each other. The first connecting part 11 and the second connecting part 12 abut against each other. Then, multiple bolts 13 are inserted between the first connecting part 11 and the second connecting part 12, and nuts are screwed onto the bolts 13, thereby connecting the first connecting part 11 and the second connecting part 12.

[0052] Therefore, through this embodiment, multiple anchor feet 1 are connected as one unit by connecting blocks, thereby improving the stability of the anchor feet 1. Even if some anchor feet 1 are not fixed and stable at the bottom of the channel 9, because they are connected to other anchor feet 1, the anchor feet 1 that are not fixed and stable will not tilt or shift, so that the anchor feet 1 can provide stable support for the stones, stone partitions 5 and other structures on the slope.
