Description

Technical Field

[0001] The present invention belongs to the technical field of greening landscape dikes, and particularly relates to an assembled landscape dike slope protection structure capable of automatically compensating water for a dike slope protection landscape by fully recycling natural precipitation, increasing the watering and maintenance period of the slope protection landscape greening, reducing the manual maintenance cost, and being convenient for installation and disassembly. Background Art

[0002] Most of the existing dikes in cities need to be decorated with greening landscapes. The dike slope protection structure only plays a role in fixing the soil and preventing soil loss caused by rainfall and watering erosion. At the same time, during the dry season in summer, in order to maintain the greening landscape effect of the dike slope protection, continuous manual watering of the slope protection greening is also required, which not only has a high labor intensity but also increases the maintenance cost of such greening landscapes. Therefore, it is necessary to design a landscape dike slope protection structure that can use the slope protection structure to store natural precipitation and slowly export and release the rainwater to the surrounding greening soil through capillary ducts, which can not only fully recycle natural precipitation but also realize automatic water compensation for the slope protection greening. Summary of the Invention

[0003] The present invention aims at the above problems and provides an assembled landscape dike slope protection structure capable of automatically compensating water for a dike slope protection landscape by fully recycling natural precipitation, increasing the watering and maintenance period of the slope protection landscape greening, reducing the manual maintenance cost, and being convenient for installation and disassembly.

[0004] The technical solution adopted by the present invention is: The assembled landscape dike slope protection structure capable of automatically compensating water includes several groups of slope protection partition members. It is characterized in that: The slope protection partition members are arranged on the dike landscape surface on the side close to the pedestrian road surface of the river-lake dike, and the slope protection partition members adopt a cross-enclosing layout form. Blocked slope protection greening landscapes are respectively arranged in the middle spaces enclosed by the slope protection partition members; moreover, cross-point connection members are respectively arranged at the cross-connection parts of the slope protection partition members.

[0005] The slope protection partition member includes a partition member main body. A water-holding cavity is arranged inside the partition member main body. A partition member upper permeable connection card slot is arranged at the upper end of the partition member main body. Permeable concrete for allowing rainwater or watering water to flow into the water-holding cavity is arranged in the partition member upper permeable connection card slot; moreover, a partition member lower closed connection card slot is arranged at the lower end of the partition member main body. So that rainwater or watering water flows into the water-holding cavity of the partition member main body through the permeable concrete in the partition member upper permeable connection card slot, thereby collecting water and fully recycling natural precipitation or watering water.

[0006] On the side wall inside the water-holding cavity, several groups of capillary water-conducting holes are provided. Water-conducting capillaries are respectively arranged in the capillary water-conducting holes, and the inner ends of the water-conducting capillaries are flush with the inner sides of the capillary water-conducting holes, while the outer ends of the water-conducting capillaries are located in the slope protection greening landscape in the corresponding area. The water-holding cavity of the slope protection separating member is also filled with water-retaining materials. In this way, the water flowing into the water-holding cavity through the upper permeable connection card slot of the separating member is temporarily gathered in the water-retaining materials (such as superabsorbent fiber cotton), and then the water in the water-retaining materials is slowly released into the planting soil of the surrounding slope protection greening landscape through the water-conducting capillaries, effectively saving urban water resources.

[0007] At the opening on the upper side of the water-holding cavity of the separating member main body, a top cover plate of the separating member is provided, and the lower side of the top cover plate of the separating member is clamped in the separating cover plate slot provided on the upper side periphery of the separating member main body. By using the top cover plate of the separating member movably arranged at the opening on the upper side of the water-holding cavity, it is convenient to clean the inside of the water-holding cavity and replace and maintain the water-retaining materials in the water-holding cavity.

[0008] The intersection connection member includes a connection member main body. A water-conducting cavity is arranged inside the connection member main body. On the left and right sides of the upper part of the connection member main body, upper closed connection clamping blocks of the connection member are respectively provided. A permeable V-shaped opening is arranged between the two upper closed connection clamping blocks of the connection member. At the permeable V-shaped opening, permeable concrete for allowing rainwater or watering water to flow into the water-conducting cavity is also provided. And on the left and right sides of the lower part of the connection member main body, lower permeable connection clamping blocks of the connection member are respectively provided. On the lower permeable connection clamping blocks of the connection member, permeable concrete for allowing the water in the water-conducting cavity to flow into the adjacent separating member is respectively provided. In this way, through the upper closed connection clamping blocks of the connection member, the intersection connection member is connected to the lower closed connection card slot at the lower end of the separating member above it, and by using the lower permeable connection clamping blocks of the connection member, the intersection connection member is connected to the upper permeable connection card slot at the upper end of the adjacent separating member below it. At the same time, through the permeable concrete at the permeable V-shaped opening, the accumulated water at the water accumulation point at the lower part of the slope protection greening landscape in each block flows into the water-conducting cavity of the intersection connection member, and then flows downward through the lower part of the water-conducting cavity and the permeable concrete on the lower permeable connection clamping blocks of the connection member into the water-holding cavity of the adjacent slope protection separating member or the lower separating member at the lower end for layer-by-layer water collection.

[0009] At the opening on the upper side of the water-conducting cavity of the connection member main body, a top cover plate of the connection member is provided, and the lower side of the top cover plate of the connection member is clamped and arranged in the connection cover plate slot on the upper side of the connection member main body. By using the top cover plate of the connection member movably arranged at the opening on the upper side of the water-conducting cavity, it is convenient to maintain and clean the inside of the water-conducting cavity.

[0010] At the upper edge of the dam landscape surface, at one end close to the upper dam road, there is an upper separating member. At the lower end of the upper separating member, there is a lower closed connection slot for the separating member. At the upper end of the upper separating member, there is a top of the upper separating part, and permeable concrete is provided on the top of the upper separating part. At the lower edge of the dam landscape surface, at one end close to the lower pedestrian road surface, there is also a lower separating member. At the upper end of the lower separating member, there is an upper permeable connection slot for the separating member. Permeable concrete is provided in the upper permeable connection slot for the separating member. At the bottom end of the lower separating member, there is a bottom of the lower separating part. The upper separating member and the lower separating member are respectively connected to the ends of the adjacent slope protection separating members through intersection connection members, and the internal structures of the upper separating member and the lower separating member are the same as those of the slope protection separating member. This is to facilitate the connection between the separating member at the uppermost end of the dam landscape surface and the side of the top dam road, and at the same time, it is also beneficial to the connection between the separating member at the lowermost end of the dam landscape surface and the side of the bottom pedestrian road surface, thereby facilitating construction and enhancing the overall aesthetics of the dam slope protection structure.

[0011] Between two adjacent groups of upper separating members or lower separating members, separating member tie bars are respectively provided. The two ends of the separating member tie bars are respectively connected to the tie bar connection holes provided on the separating member. To enhance the structural stability of the upper and lower ends of the entire landscape dam slope protection structure through the separating member tie bars and extend the service life of the project.

[0012] Between the slope protection separating member and the slope protection greening landscape and the dam main structure below them, there is a dam gravel cushion layer. By using the dam gravel cushion layer, the load of the planting soil of the separating member and the slope protection greening landscape on the dam's own structure can be made more even, preventing uneven settlement of the separating member and avoiding adverse effects on the overall structure of the dam.

[0013] The construction method of the above-mentioned prefabricated landscape dam slope protection structure that can achieve automatic water compensation is characterized by including the following steps:

[0014] Step 1: Lay a layer of dam gravel cushion layer on the dam structure surface of the river-lake dam. After that, lay a layer of geotextile above the dam gravel cushion layer, and install separating members (including lower separating members, slope protection separating members, and upper separating members) layer by layer from bottom to top on the upper layer of the geotextile;

[0015] Step 2: Embed the lower part of the lower separating member into the bottom structure layer of the pedestrian road surface or the vertical structure surface on the roadside. Then, tighten two adjacent groups of lower separating members with separating member tie bars, and place the ends of the separating member tie bars into the tie bar connection holes on the separating member;

[0016] Step 3: Install the intersection connection member at the upper intersection point above the lower partition member. Connect the lower water-permeable connection blocks of the connection member at the lower part of the intersection connection member to the upper water-permeable connection slots of the partition member at the upper end of the lower partition member respectively. Moreover, connect the lower closed connection slot of the partition member at the lower end of the upper slope protection partition member to the upper closed connection block of the connection member at the upper part of the intersection connection member. Connect the slope protection partition members to the intersection connection members layer by layer upwards until the top of the river-lake dam slope protection;

[0017] Step 4: Connect the lower closed connection slot of the upper partition member at the top to the upper closed connection block of the intersection connection member at the topmost layer, and embed the upper part of the upper partition member into the bottom structural layer of the dam road. Then, tighten the adjacent two groups of upper partition members with partition member tie bars;

[0018] Step 5: Place multiple water guide capillaries into the capillary water guide holes on both sides of the water holding cavity of each partition member and align them. The outer sides of the water guide capillaries are placed in the landscape planting area surrounded by the partition members on the periphery. Then, fill the water holding cavities of each partition member with water retaining materials, and use the top cover plates of the partition members and the top cover plates of the connection members to cover the upper openings of the partition members and the intersection connection members respectively;

[0019] Step 6: After the dam slope protection structure is laid, cover the dam landscape surface with planting soil. According to the specific landscape effect requirements, the covering soil of the slope protection greening landscape can be flush with the dam slope protection structure or slightly higher than the top of the structure, and the water guide capillaries are evenly covered inside the soil, so as to automatically inject rainwater or watering water into the structure for water retention and slow release.

[0020] Advantages of the present invention: Since the present invention adopts several groups of slope protection partition members, the slope protection partition members are arranged on the dam landscape surface on the side close to the pedestrian road surface of the river-lake dam. The slope protection partition members adopt a cross-enclosing layout form. Blocked slope protection greening landscapes are respectively arranged in the middle spaces enclosed by the slope protection partition members. The cross-connected parts of the slope protection partition members respectively adopt the structural form of intersection connection members. Therefore, its design is reasonable and the structure is compact, and it can be implemented or transformed according to the urban area and climate characteristics. After natural rainfall, rainwater can be collected and stored through the cavities and water retaining materials of the structure, saving a certain amount of urban water resources. During the long-term drought and less rain period in summer, it is also possible to fully water manually, fill the cavities of the members with water at one time, and slowly release the water to the greening landscape through capillary and transpiration effects, extending the maintenance period of the dam slope protection greening. Compared with a simple slope protection and soil fixation structure, its functionality is stronger, similar to the sponge city theory in urban space.

[0021] The advantages compared with the existing slope protection dam structures are as follows: 1. The structural practice is stable and can be widely applied in areas with little rain in summer. The automatic water collection and slow release functions of the structure greatly reduce the later maintenance cost of this greening landscape. In addition to the dam slope protection, this automatic water compensation structure system can be adopted at locations with slope protection green space landscape functions in the city.

[0022] 2. The structural form and modulus are variable. According to the requirements of the site scale and landscape conditions, the structural dimensions and connection forms can be adaptively designed while the structural principle remains unchanged.

[0023] 3. This structure adopts standard modular installation. Its components can be installed by simple plugging. The construction is simple and convenient, and can be prefabricated in advance according to the characteristics of the shape and size of the implementation or renovation site, and formed in one construction on site, effectively shortening the construction period of the dam slope protection and reducing the later maintenance cost.

[0024] 4. The modular components that make up this structure system can be disassembled and opened, which is convenient for later maintenance and repair, and the replacement of local modules is convenient.

[0025] 5. The present invention makes full use of the natural precipitation in the city. Through the water collection and slow release process of the slope protection structure, the automatic water compensation function of the greening landscape is realized, reducing the costs of greening and manual maintenance. It belongs to a low-impact development mode of the urban green space landscape system and has a wide application range. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0038] According to Figures 1 to 11 The specific structure of the present invention will be described in detail. The prefabricated landscape dam slope protection structure capable of realizing automatic water compensation includes a plurality of groups of slope protection separation members 5, which are arranged on the dam landscape surface 3 on the side of the river-lake dam 1 close to the pedestrian road surface 8, and each group of slope protection separation members 5 adopts a cross-enclosing layout form. Block-shaped slope protection greening landscapes 7 are respectively arranged in the middle spaces enclosed by the slope protection separation members 5. Between the slope protection separation members 5 and the slope protection greening landscapes 7 and the dam main body structure below them, a dam gravel cushion 4 is provided, and then the dam gravel cushion 4 is used to make the loads of the separation members (including the slope protection separation members 5, the upper end separation members 10 and the lower end separation members 11) and the planting soil of the slope protection greening landscapes 7 on the dam structure itself more evenly distributed, so as to prevent uneven settlement of the separation members and avoid adverse effects on the overall structure of the dam caused by different loads of the planting soil of the slope protection greening landscapes 7 and the separation members.

[0039] The slope protection separation member 5 is composed of a separation member main body 12. A water holding cavity 16 is arranged inside the separation member main body 12. The lower side of the water holding cavity 16 is a closed structure, and an opening is arranged on the upper side of the water holding cavity 16. A separation member upper permeable connection clamping groove 13 is arranged at the upper end of the separation member main body 12, and permeable concrete 14 for allowing rainwater or watering to flow into the water holding cavity 16 is arranged in the separation member upper permeable connection clamping groove 13; at the lower end of the separation member main body 12, a separation member lower closed connection clamping groove 15 is arranged. On the left and right side walls inside the water holding cavity 16 of the slope protection separation member 5, several groups of capillary water guiding holes 18 are respectively arranged; and water guiding capillary tubes 30 made of corrosion-resistant rubber materials are respectively arranged in the capillary water guiding holes 18. The inner end of the water guiding capillary tube 30 is flush with the inner side of the capillary water guiding hole 18, and the outer end of the water guiding capillary tube 30 is located in the planting soil of the slope protection greening landscape 7 in the corresponding area. At the same time, a water retaining material 17 (such as superabsorbent fiber cotton) is also filled in the water holding cavity 16 of the slope protection separation member 5.

[0040] Thus, rainwater or watering flows into the water holding cavity 16 of the separation member main body 12 through the permeable concrete 14 in the separation member upper permeable connection clamping groove 13 for water collection, and natural precipitation or watering is fully recycled. And the water flowing into the water holding cavity 16 through the permeable concrete 14 in the separation member upper permeable connection clamping groove 13 is temporarily gathered in the water retaining material 17. Then, when the soil of the slope protection greening landscape 7 is relatively dry and needs to be replenished with water, the water in the water retaining material 17 of the separation member will be slowly released into the planting soil of the surrounding slope protection greening landscape 7 through the water guiding capillary tubes 30, effectively saving urban water resources. At the opening on the upper side of the water holding cavity 16 of the separation member main body 12, a separation member top cover plate 20 is also arranged; and the lower side of the separation member top cover plate 20 is clamped in a separation cover plate clamping groove 19 arranged on the upper side periphery of the separation member main body 12; furthermore, by using the separation member top cover plate 20 movably arranged at the opening on the upper side of the water holding cavity 16, it is convenient to clean the inside of the water holding cavity 16 and replace and maintain the water retaining material 17 in the water holding cavity 16.

[0041] At the upper edge of the dam landscape surface 3, at one end close to the upper dam road 2, there is an upper end separating member 10. At the lower end of the upper end separating member 10, there is a lower closed connection slot 15 for the separating member; at the upper end of the upper end separating member 10, there is an upper separating member top 28 for cooperating with the top dam road 2, and permeable concrete 14 is provided on the upper separating member top 28. At the lower edge of the dam landscape surface 3, at one end close to the lower pedestrian road surface 8, there is also a lower end separating member 11. At the upper end of the lower end separating member 11, there is an upper permeable connection slot 13 for the separating member, and permeable concrete 14 is provided in the upper permeable connection slot 13 for the separating member; at the bottom end of the lower end separating member 11, there is a lower separating member bottom 29 for cooperating with the bottom pedestrian road surface 8. The lower end of the upper end separating member 10 and the upper end of the lower end separating member 11 are respectively connected to the ends of the adjacent slope protection separating members 5 through the intersection connection members 6.

[0042] Moreover, the upper end separating member 10 and the lower end separating member 11 have the same internal structure as the slope protection separating member 5, and both are composed of a separating member main body 12; a water holding cavity 16 is provided inside the separating member main body 12 of the upper end separating member 10 and the lower end separating member 11, and several groups of capillary water guiding holes 18 for connecting with the water guiding capillary 30 are respectively provided on the side walls of the left and right sides inside the water holding cavity 16. This is to facilitate the connection between the separating member at the uppermost end of the dam landscape surface 3 and the end side of the top dam road 2. At the same time, it is also beneficial to the connection between the separating member at the lowermost end of the dam landscape surface 3 and the end side of the bottom pedestrian road surface 8, thereby facilitating construction and improving the overall aesthetics of the dam slope protection structure. Furthermore, between two adjacent groups of upper end separating members 10 and between two adjacent groups of lower end separating members 11, there are respectively provided separating member tie bars 32. The two ends of the separating member tie bars 32 are respectively connected to the tie bar connection holes 33 provided on the upper end separating member 10 and the lower end separating member 11, and thus the structural stability of the upper and lower ends of the entire landscape dam slope protection structure is enhanced through the separating member tie bars 32, and the service life of the project is extended.

[0043] At the intersecting and connecting parts of the slope protection separating member 5, the upper end separating member 10, and the lower end separating member 11, intersection point connecting members 6 are respectively provided. The intersection point connecting member 6 is composed of a connecting member main body 21 in a "×" shape. A water guiding cavity 24 is arranged inside the connecting member main body 21. The lower side of the water guiding cavity 24 is a closed structure, and an opening is arranged on the upper side of the water guiding cavity 24. On the left and right sides of the upper part of the connecting member main body 21, connecting member upper closed connecting blocks 22 are respectively arranged. A permeable V-shaped opening 23 is arranged between the two connecting member upper closed connecting blocks 22; and permeable concrete 14 for allowing rainwater or watering to flow into the water guiding cavity 24 is also arranged at the permeable V-shaped opening 23. At the same time, on the left and right sides of the lower part of the connecting member main body 21, connecting member lower permeable connecting blocks 25 are respectively arranged; and permeable concrete 14 for allowing the water in the water guiding cavity 24 to flow into the adjacent separating member below is respectively arranged on the two connecting member lower permeable connecting blocks 25.

[0044] Furthermore, through the connecting member upper closed connecting block 22, the intersection point connecting member 6 is connected to the separating member lower closed connecting slot 15 at the lower end of the separating member (slope protection separating member 5 or upper end separating member 10) above it; and the connecting member lower permeable connecting block 25 is used to connect the intersection point connecting member 6 to the separating member upper permeable connecting slot 13 at the upper end of the separating member (slope protection separating member 5 or lower end separating member 11) below it. Moreover, through the permeable concrete 14 at the permeable V-shaped opening 23 between the two connecting member upper closed connecting blocks 22, the accumulated water at the lower slope water accumulation point 31 of the slope greening landscape 7 in each block flows into the water guiding cavity 24 of the intersection point connecting member 6; then, the accumulated water flows downward through the permeable concrete 14 on the lower part of the water guiding cavity 24 and on the connecting member lower permeable connecting block 25 into the water holding cavity 16 of the adjacent slope protection separating member 5 or lower end separating member 11 for layer-by-layer water collection. A connecting member top cover plate 27 is arranged at the opening on the upper side of the water guiding cavity 24 of the connecting member main body 21, and the lower side of the connecting member top cover plate 27 is clamped and arranged in a plurality of connecting cover plates slots 26 arranged on the upper side of the connecting member main body 21; so as to facilitate the maintenance and cleaning of the inside of the water guiding cavity 24 by using the connecting member top cover plate 27 movably arranged at the opening on the upper side of the water guiding cavity 24.

[0045] When constructing the prefabricated landscape dam slope protection structure capable of realizing automatic water compensation, the following steps are adopted:

[0046] Step 1, lay a layer of dam gravel cushion 4 on the dam structure surface of the river-lake dam 1; then, lay a geotextile above the dam gravel cushion 4, and install separating members (including the lower end separating member 11, the slope protection separating member 5, and the upper end separating member 10) layer by layer from bottom to top on the upper layer of the geotextile.

[0047] Step 2: Embed the lower part of the lower end separating member 11 into the bottom structural layer of the pedestrian pavement 8 or the vertical structural surface on the roadside; then, tighten two adjacent groups of lower end separating members 11 with the separating member tie bars 32, and place the ends of the separating member tie bars 32 into the tie bar connection holes 33 on the lower end separating members 11.

[0048] Step 3: Install the intersection connection member 6 at the upper intersection point of the lower end separating member 11, and connect the lower connection member permeable connection blocks 25 at the lower part of the intersection connection member 6 with the separating member upper permeable connection slots 13 at the upper end of the lower end separating member 11 respectively; moreover, connect the separating member lower closed connection slots 15 at the lower end of the upper slope protection separating member 5 with the connection member upper closed connection blocks 22 at the upper part of the intersection connection member 6. Connect and install the slope protection separating members 5 layer by layer upward with the corresponding intersection connection members 6 until the top of the slope protection of the river-lake dam 1.

[0049] Step 4: Connect the separating member lower closed connection slots 15 at the lower end of the upper end separating member 10 at the top with the connection member upper closed connection blocks 22 at the upper part of the topmost intersection connection member 6, and embed the upper part of the upper end separating member 10 into the bottom structural layer of the dam road 2; then, tighten two adjacent groups of upper end separating members 10 with the separating member tie bars 32 respectively, and place the ends of the separating member tie bars 32 into the tie bar connection holes 33 on the upper end separating members 10.

[0050] Step 5: Place a plurality of water guiding capillary tubes 30 into the capillary water guiding holes 18 on both sides of the water holding cavities 16 of each separating member respectively and align the ends, and place the outer sides of the water guiding capillary tubes 30 in the landscape planting areas surrounded by the separating members on the periphery. Then, fill the water holding cavities 16 of each separating member with water retaining materials 17 (super absorbent fiber cotton); and use the separating member top covers 20 and the connection member top covers 27 to cover the upper openings of the separating member and the intersection connection member 6 respectively to form a closed structure.

[0051] Step 6: After the dam slope protection structure is laid, cover planting soil in the middle space formed by the intersecting and enclosing separating members and on the upper part of the dam slope protection members respectively, so as to form an overall slope protection greening landscape 7; and the water guiding capillary tubes 30 are evenly covered inside the soil, so as to automatically inject rainwater or watering water into the structure for water retention and slow release. According to the specific landscape effect requirements, the covering soil of the slope protection greening landscape 7 can be flush with the dam slope protection structure or slightly higher than the top of the structure.

[0052] The prefabricated landscape dike slope protection structure capable of realizing automatic water compensation utilizes a hollow slope protection structure, combined with water-retaining materials (superabsorbent fiber cotton) and water-conducting capillary tubes. While ensuring the stability of the soil covering for the slope protection greening landscape of the dike, it slowly guides and releases rainwater to the surrounding greening soil through capillary ducts. This can not only fully recycle and utilize natural precipitation but also realize the automatic water compensation for the slope protection greening, increase the watering and maintenance cycle of the slope protection greening landscape of the dike, reduce the manual maintenance cost, and effectively solve the problem of continuous watering and maintenance of the slope protection landscape greening in summer. Moreover, this structure adopts the form of assembled components, which is convenient for installation, disassembly, and later maintenance.
