Description

Technical Field

[0001] The present application relates to the technical field of water conservancy engineering, and in particular to a stepped ecological landscape slope protection. Background Art

[0002] Ecological landscape slope protection refers to a comprehensive slope protection project that combines ecological protection and landscape design. This comprehensive slope protection project can not only maintain the stability of the river embankment slope protection soil, but also pay more attention to the beauty that the slope protection brings to people and the restoration of the original ecological environment. With the continuous development of slope protection construction technology, slope protection can be roughly divided into concrete slope protection, gabion slope protection, mesh slope protection and plant slope protection, etc.

[0003] The stepped ecological landscape slope protection, as the name suggests, is based on the local geological conditions and is divided into several distinct steps according to a certain slope and proportion. On the one hand, it reflects the staggered functional areas of the slope protection. On the other hand, plants with strong soil-fixing properties are planted on each step to reduce the rate of soil erosion, thereby enhancing the stability of the slope protection and being able to withstand more severe natural environments such as storms and floods.

[0004] Common stepped ecological landscape slope protection is formed by piling up larger solid stones on the slope protection. However, solid stones are not only heavy and difficult to carry and stack, which increases the labor load of operators, but also the stones themselves do not contain soil, making it difficult to plant and cultivate soil-fixing plants through the stones, which restricts the number and planting area of ​​soil-fixing plants. Summary of the Invention

[0005] In order to reduce the workload of operators and plant more soil-fixing plants, the present application provides a stepped ecological landscape slope protection.

[0006] This application provides a stepped ecological landscape slope protection, which adopts the following technical solutions:

[0007] A stepped ecological landscape slope protection comprises several steps, each step comprises several unit blocks, each unit block has a cavity running through it from top to bottom, the cavity is filled with a filler, and the filler is made of a mixture of stones and soil, the side walls of the unit blocks are provided with water holes, and the water holes and the cavity are interconnected.

[0008] Through the above technical solution, during the construction phase of the river bank protection, several steps are formed by stacking unit blocks. The unit blocks can be made of materials such as stones and fired blocks. Since the unit blocks have cavities, on the one hand, this reduces the weight of the unit blocks, thereby reducing the workload of operators in handling the unit blocks. On the other hand, operators can fill the cavities of the unit blocks with stones and soil, which not only maintains the total weight of the unit blocks and the filler, but also allows the planting of soil-fixing plants in the filler, allowing operators to plant more soil-fixing plants in the unit blocks, thereby enhancing the stabilization effect of the slope protection structure on the slope soil.

[0009] In addition, since the unit block is provided with water-permeable holes, on the one hand, the structural deadweight of the unit block is further reduced, and on the other hand, the water accumulated in the unit block is easily discharged along the water-permeable holes.

[0010] In summary, this structure can not only reduce the labor load of operators in carrying unit blocks, but also expand the planting area of ​​soil-fixing green plants, thereby increasing the number of soil-fixing green plants planted.

[0011] In a preferred example, the present application can be further configured as follows: adjacent unit blocks on the steps of different levels are staggered in sequence.

[0012] Through the above technical solution, since adjacent unit blocks on different steps are staggered with each other, the unit blocks on the upper layer can exert pressure on the two adjacent unit blocks on the lower layer, thereby stabilizing the above two adjacent unit blocks and further increasing the stability of the slope protection structure.

[0013] In a preferred example, the present application can be further configured as follows: a sink groove is opened on the top surface of the unit block, and the sink grooves on adjacent unit blocks on the same level of the step are spliced ​​to form a drainage trough.

[0014] Through the above technical solution, in the event of rainfall, rainwater can naturally fall into the trough on the top surface of the unit block, and the rainwater can gradually flow along the trough, and the troughs on two adjacent unit blocks can be spliced ​​to form a drainage trough to increase the flow cross-section through which water flows, thereby enhancing the drainage capacity of the unit block, reducing the rainwater accumulated in the unit block, and further reducing the possibility of drowning and inactivation of soil-fixing green plants planted in the unit block.

[0015] In a preferred example, the present application can be further configured as follows: a through groove is provided on the unit block, the through groove and the cavity are communicated with each other, a filter is provided in the through groove, a sliding groove is provided on the unit block, the sliding groove and the through groove are communicated with each other, a blocking plate is slidably provided in the sliding groove, and the filter is located on the side of the blocking plate close to the cavity.

[0016] Through the above technical solution, for the unit blocks piled at a lower elevation, when the location of the slope protection is in the flood season, there is a possibility that the water level in the river channel will gradually rise. When the water level reaches the unit block, the operator inserts the baffle plate into the sliding groove so that the baffle plate closes the sliding groove to reduce the erosion of the soil in the unit block by rainwater, thereby reducing the impact of soil erosion on the slope.

[0017] During the non-flood season, the water level is usually below the unit block. At this time, the operator will remove the baffle and the filter net will block the stones and soil in the cavity of the unit block to reduce the possibility of stones and soil falling into the water flow. In addition, the filter net can also maintain the smooth flow of water in the unit block.

[0018] In a preferred example, the present application can be further configured as follows: an arc groove 1 is provided on the unit block, and an arc groove 2 is also provided on the unit block, the radius of the arc groove 1 and the radius of the arc groove 2 are consistent, an arc bar is slidably provided in the arc groove 1, and the arc bar can slide along the arc groove 1 to the arc groove 2 on the upper adjacent unit block, an arc block is slidably provided in the arc groove 1, and the arc block can push the arc bar to slide, and a blocking mechanism is provided in the arc groove 1, and the blocking mechanism is used to prevent the arc bar from falling back.

[0019] With the above technical solution, before the operator places the upper unit block on the lower unit block, the operator slides the arc bar into the arc groove 1 of the lower unit block. After the operator places the upper unit block on the lower unit block and aligns the arc groove 2 on the upper unit block with the arc groove 1 on the lower unit block, the operator inserts the arc block into the arc groove 1 on the lower unit block and pushes the arc block to slide downward along the arc groove 1. At this time, the arc block pushes the arc bar to slide upward and enter the upper arc groove 2. The arc bar and the arc block are both made of materials with sufficient rigidity. At this time, the upper and lower unit blocks are connected under the obstruction of the arc bar 1, thereby reducing the possibility of the upper and lower unit blocks separating from each other.

[0020] After that, the operator uses the blocking mechanism to prevent the arc bar from falling back to maintain the connection between the upper and lower unit blocks.

[0021] In a preferred example, the present application can be further configured as follows: the blocking mechanism includes a plurality of gravels, the plurality of gravels are filled in the arc-shaped groove one, the inner wall at the end of the arc-shaped groove one is provided with a plurality of blocking grooves, and the gravels abut against the inner wall of the blocking groove.

[0022] Through the above technical solution, when the operator pushes the arc block to make the arc bar enter the arc groove 2 of the upper unit block, a number of crushed stones are placed into the lower unit block and the crushed stones are appropriately squeezed to reduce the gaps between the crushed stones, so that the sharp corners of the crushed stones are stuck in the blocking groove. At this time, under the obstruction of the crushed stones, the possibility of the arc block sliding is reduced, and the possibility of the arc bar falling back is also reduced, thereby maintaining the connection between the upper and lower unit blocks.

[0023] In a preferred example, the present application can be further configured as follows: a plurality of socket rods are provided on the bottom surface of the unit block, a plurality of socket holes are opened on the unit block, a plurality of the socket rods and a plurality of the socket holes are provided in a one-to-one correspondence, and the socket holes are used for the corresponding socket rods to be plugged in.

[0024] Through the above technical solution, when the operator stacks another layer of unit blocks on the unit block, the socket rod on the upper unit block is inserted into the socket hole on the lower unit block. On the one hand, the integrity between the upper and lower unit blocks is further improved. On the other hand, this can position the upper unit block and improve the accuracy of the docking between the arc groove 2 of the upper unit block and the arc groove 1 of the lower unit block.

[0025] In a preferred example, the present application can be further configured as follows: a through hole is opened on the unit block, a reinforcement rod is inserted into the through hole, and the length of the reinforcement rod is greater than the height of the unit block.

[0026] Through the above technical solution, after the operator piles the unit blocks on the slope, the reinforcing rods are inserted into the through holes on the unit blocks and then into the soil on the slope to improve the stability of the unit blocks.

[0027] In a preferred example, the present application can be further configured as follows: a connecting plate is provided between the reinforcing rods on two adjacent unit blocks on the same level of the step, and a connecting hole is provided on the connecting plate for the reinforcing rod to pass through.

[0028] Through the above technical solution, the integrity between the two adjacent unit blocks is improved due to the connecting action of the connecting plate on the reinforcement rods of the two adjacent unit blocks.

[0029] In a preferred example, the present application can be further configured as follows: a connecting block is provided between the adjacent unit blocks on the same level of the step, a connecting protrusion is provided on the connecting block, and a groove for accommodating the connecting block and the connecting protrusion is opened on the unit block.

[0030] Through the above technical solution, after the operator places two adjacent unit blocks on the slope, the two ends of the connecting block are respectively placed into the grooves on the two adjacent unit blocks. At this time, under the obstruction of the connecting protrusion, the integrity between the two unit blocks is further improved.

[0031] In summary, this application has the following beneficial technical effects:

[0032] 1. Since there is a cavity in the unit block, it not only reduces the structural deadweight of the unit block and reduces the labor load of operators in carrying the unit block, but also the cavity is filled with a mixture of stones and soil, which expands the planting area of ​​soil-fixing green plants, thereby enabling the planting of more soil-fixing green plants;

[0033] 2. When the slope protection is in the flood season, a baffle is inserted into the sliding groove to close the sliding groove to reduce the erosion of the soil in the unit block by rainwater, thereby reducing the impact of soil erosion on the slope; in the non-flood season, the baffle is removed and the filter net is used to block the stones and soil in the cavity of the unit block to reduce the possibility of stones and soil falling into the water flow. In addition, the filter net can also maintain the smooth flow of water in the unit block;

[0034] 3. The operator pushes the arc bar in the lower unit block so that the arc bar enters the arc groove 2 in the upper unit block. Under the obstruction of the arc bar, the connection between the upper and lower unit blocks is completed, thereby reducing the possibility of separation of the upper and lower unit blocks.

[0043] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0044] The embodiments of the present application disclose a stepped ecological landscape slope protection.

[0045] Refer to the attached Figure 1 and attached Figure 2 As shown, a stepped ecological landscape slope protection includes several steps 1, each of which has the same width (the width of the step 1 can be slightly adjusted according to the actual slope topography). Each step 1 includes several unit blocks 2, which are made of stone, fired blocks, or prefabricated blocks.

[0046] Refer to the attached Figure 1 and attached Figure 2 As shown, several unit blocks 2 on the same level are aligned and closely arranged. Adjacent unit blocks 2 on different steps 1 are staggered in sequence. Therefore, the unit blocks 2 on the upper level exert a covering weight pressure on the two adjacent unit blocks 2 on the lower level, thereby stabilizing the two adjacent unit blocks 2 on the lower level and increasing the stability of the slope protection structure.

[0047] Refer to the attached Figure 1 and attached Figure 2 As shown, each unit block 2 has a cavity 11 extending from top to bottom to reduce the weight of the unit block 2 and the workload of operators handling the unit block 2. Cavity 11 is filled with a mixture of rocks and soil to increase the planting area for soil-fixing plants, allowing for more soil-fixing plants to be planted. Fine sand can also be added to the filler to increase its weight and density.

[0048] Refer to the attached Figure 1 and attached Figure 2As shown, water holes 12 are formed through the four side walls of the unit block 2 to facilitate the drainage of water accumulated in the unit block 2 along the water holes 12. Each water hole 12 is located at the bottom of the unit block 2, and each water hole 12 and the cavity 11 are interconnected. The water holes 12 on adjacent unit blocks 2 on the same step 1 can be aligned with each other to facilitate water flow.

[0049] Refer to the attached Figure 1 and attached Figure 2 As shown, the top surface of each unit block 2 is provided with a trough 13, distributed along the edge of the top surface of the unit block 2. The troughs 13 of adjacent unit blocks 2 on the same step 1 are connected to form a drainage channel 14, thereby increasing the flow cross-section of the water body. During rainy weather in the area where this structure is located, rainwater can flow through the drainage channels 14 with a larger flow cross-section, reducing the amount of rainwater accumulated in the unit block 2, thereby reducing the possibility of drowning and inactivation of soil-stabilizing green plants.

[0050] Refer to the attached Figure 2 and attached Figure 3 As shown, a through slot 15 is horizontally provided on one side of the unit block 2. The through slot 15 communicates with the cavity 11. A filter 151, which can be made of wire mesh, is disposed within the through slot 15. A sliding slot 16 is vertically provided on the unit block 2. The sliding slot 16 and the through slot 15 are located on the same side of the unit block 2 and communicate with each other. A blocking plate 161 is slidably disposed within the sliding slot 16. The blocking plate 161 is used to seal the sliding slot 16 and is made of steel or other hard plate material. The filter 151 is located on the side of the blocking plate 161 closest to the cavity 11.

[0051] During the flood season, when the river water level rises, operators insert baffles 161 into sliding slots 16, sealing them to reduce rainwater erosion of the soil within unit blocks 2 and mitigate the impact of soil erosion on the slope. During the non-flood season, baffles 161 are removed, and filter screen 151 blocks rocks and soil within cavities 11 of unit blocks 2, reducing the likelihood of them falling into the water flow. Filter screen 151 also maintains the unimpeded flow of water within unit blocks 2.

[0052] Refer to the attached Figure 4 and attached Figure 5 As shown, the top surface of the unit block 2 is provided with an arc-shaped groove 101, and the central angle of the arc-shaped groove 101 is 180 degrees. The bottom surface of the unit block 2 is also provided with an arc-shaped groove 102, and the central angle of the arc-shaped groove 102 is between 70 degrees and 90 degrees. The radii of the arc-shaped groove 101 and the arc-shaped groove 102 are the same, and the cross-sections of the arc-shaped groove 101 and the arc-shaped groove 102 are both rectangular.

[0053] Refer to the attached Figure 4 and attached Figure 5 As shown, an arcuate bar 3 is slidably disposed within arcuate groove 101. The arcuate bar 3 can slide along arcuate groove 101 into arcuate groove 2 102 on the upper adjacent unit block 2, thereby limiting the upper unit block 2 and completing the connection between the two adjacent unit blocks 2. An arcuate block 4 is slidably disposed within arcuate groove 101. Both the arcuate bar 3 and the arcuate block 4 are made of sufficiently rigid materials. The arcuate block 4 can push the arcuate bar 3 to slide, thereby allowing the arcuate bar 3 to enter arcuate groove 2 102 on the upper adjacent unit block 2.

[0054] Refer to the attached Figure 4 and attached Figure 5 As shown, a blocking mechanism 5 for preventing the arc strip 3 from falling back is provided in the arc groove 101. The blocking mechanism 5 includes a plurality of irregularly shaped polygonal gravels. The gravels are made of stones with relatively high hardness. The plurality of gravels are filled in the end of the arc groove 101 away from the arc strip 3. The inner wall of the end of the arc groove 101 away from the arc strip 3 is provided with a plurality of blocking grooves 103. The gravels and the inner wall of the blocking groove 103 are in abutment with each other.

[0055] Refer to the attached Figure 4 and attached Figure 5 As shown, the bottom surface of the unit block 2 is provided with a plurality of vertically arranged socket rods 17, the socket rods 17 and the unit block 2 are integrally formed, and a plurality of socket holes 171 are opened on the unit block 2, and the plurality of socket rods 17 and the plurality of socket holes 171 are arranged in a one-to-one correspondence. The socket holes 171 are used for the corresponding socket rods 17 to be plugged in, so as to facilitate the positioning of the upper unit block 2, thereby improving the accuracy of the docking between the arc groove 2 102 of the upper unit block 2 and the arc groove 1 101 of the lower unit block 2.

[0056] Before the operator places the upper unit block 2 on the lower unit block 2, the arc strip 3 is slid into the arc groove 1 101 of the lower unit block 2 in advance, and then the upper unit block 2 is placed on the lower unit block 2, so that the socket rod 17 on the upper unit block 2 is inserted into the socket hole 171 on the lower unit block 2, completing the docking of the arc groove 1 101 and the arc groove 2 102 on the upper and lower adjacent unit blocks 2.

[0057] At this time, the operator inserts the arc block 4 into the arc groove 1 101 on the lower unit block 2, and pushes the arc block 4 to slide downward, so that the arc block 4 pushes the arc bar 3 into the arc groove 2 102 on the upper unit block 2, and then embeds a number of gravel into the arc groove 1 101 on the lower unit block 2, and squeezes the gravel with appropriate force, so that the gravel is pressed against the arc block 4 and the inner wall of the blocking groove 103. In this way, under the obstruction of the arc block 4 and the gravel, the possibility of the arc bar 3 falling back is reduced, so that the arc bar 3 can be maintained in the arc groove 2 102 of the upper unit block 2, and the connection between the upper and lower unit blocks 2 can be maintained.

[0058] Refer to the attached Figure 1 and attached Figure 2 As shown, two through holes 18 are vertically penetrated on the unit block 2, and a vertically arranged reinforcement rod 181 is inserted into each through hole 18. The bottom end of the reinforcement rod 181 is pointed, and the length of the reinforcement rod 181 is greater than the height of the unit block 2, so that the reinforcement rod 181 can be inserted into the soil after passing through the unit block 2 to enhance the stability of the unit block 2. A connecting plate 6 is provided between the reinforcement rods 181 on two adjacent unit blocks 2 on the same step 1. The connecting plate 6 is arranged horizontally and has a connecting hole 61 vertically penetrated on the connecting plate 6 for the reinforcement rod 181 to pass through. Under the restraining effect of the connecting plate 6 on the two adjacent reinforcement rods 181, the integrity between the two adjacent unit blocks 2 is improved.

[0059] Refer to the attached Figure 1 and attached Figure 6 As shown, a connecting block 7 is provided between adjacent unit blocks 2 on the same step 1. The connecting block 7 is provided with two spike-shaped connecting protrusions 71. The two connecting protrusions 71 are integrally formed with the connecting block 7, and the two connecting protrusions 71 face opposite directions, one at each end of the connecting block 7 and the other on either side of the connecting block 7. A groove 19 is provided on the unit block 2 for accommodating the connecting block 7 and the connecting protrusions 71. The groove 19 fits in with the connecting block 7 and the connecting protrusions 71. The operator places the two ends of the connecting block 7 into the grooves 19 on the adjacent unit blocks 2. The obstruction of the connecting protrusions 71 further enhances the integrity between the two unit blocks 2.

[0060] The implementation principle of this embodiment is: the unit blocks 2 of the slope protection structure are stacked and made of materials such as stones and fired blocks. A cavity 11 is opened in the unit block 2 to reduce the weight of the unit block 2, which is the labor load of the operator in carrying the unit block 2 at a time. The operator can fill the cavity 11 of the unit block 2 with a mixture of stones and soil to expand the planting area of ​​soil-fixing green plants, so that more soil-fixing plants can be planted.

[0061] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application in turn. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
