Description

Technical Field

[0001] This utility model relates to the field of riverbank slope protection and landscape design, specifically a landscape protection structure for backwater riverbank slopes. Background Technology

[0002] Riverbank slopes, as the transitional zone between river water and land, have significant ecological and engineering importance. They not only stabilize river morphology and buffer flood erosion, but also provide channels for the exchange of matter, energy, and information between aquatic and terrestrial ecosystems. In river ecological construction, effective slope protection on both sides of the river is crucial for improving river stability and enhancing the landscape.

[0003] Traditional riverbank protection methods are diverse, including masonry and dry-laid riprap slope protection, concrete block slope protection, and cast-in-place concrete slope protection. These slope protection structures can maintain the stability of the bank slope, prevent soil erosion, and control floods and drainage to a certain extent. However, these slope protection projects are relatively expensive and difficult to construct. Moreover, they have adverse effects on the landscape, environment, and ecology to varying degrees, disrupting the original ecological balance between the water body and the terrestrial environment and causing damage to the ecosystem function. Therefore, this utility model provides a landscape protection structure for backwater riverbank slopes. Utility Model Content

[0004] To address the problems of high construction costs and disruption of the original ecological balance between water and land environments caused by traditional riverbank protection structures, which lead to damage to ecosystem functions, this utility model provides a landscape protection structure for backwater riverbank slopes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A landscape protection structure for backwater channel slopes, comprising:

[0007] The underwater slope protection is provided with a toe protection concrete at the bottom, and the return water level and the current water level are both located on the underwater slope protection.

[0032] Please refer to the attached document. Figures 1-2 This application illustrates a landscape protection structure for a backwater channel slope provided by an embodiment of the present application. It is used for the protection of the backwater channel slope and to meet the daily exercise needs of citizens. It includes: an underwater slope protection 2, a leisure walkway 3, a turf slope protection 4, and a pedestrian walkway structure 5.

[0033] like Figure 1 , Figure 2 As shown, the bottom of the underwater slope 2 is provided with a foot protection concrete 1, the return water level and the current water level are both on the underwater slope 2, the leisure walkway 3 is fixedly installed at the top of the underwater slope 2, and the turf slope 4 is installed on the sidewalk structure 5 of the leisure walkway 3 away from the underwater slope 2. The sidewalk structure 5 is installed at the top of the turf slope 4.

[0034] Furthermore, the underwater slope protection 2 includes, from bottom to top, the following layers: impermeable geotextile layer 21, sand and gravel cushion layer 22, and hexagonal concrete brick layer 23.

[0035] The leisure trail 3 includes: trail subbase 31, trail frame 33, and trail anti-corrosion wood 34.

[0036] The walkway frame 33 is installed above the walkway subbase 31, and the anti-corrosion wood 34 is fixedly installed on the walkway frame 33 in the longitudinal direction. Both sides of the walkway subbase 31 and the anti-corrosion wood 34 are fixedly provided with walkway curb stones 32.

[0037] The sidewalk structure 5 includes: a sidewalk sand cushion layer 52, sidewalk bricks 53, and sidewalk curb stones 51. The sidewalk bricks 53 are laid on the sidewalk sand cushion layer 52, and the sidewalk curb stones 51 are set on both sides of the sidewalk bricks 53.

[0038] The specific construction process is as follows:

[0039] Construction of foot protection concrete 1

[0040] Basic cleaning and measurement: First, the bottom of the backwater channel slope is cleaned to remove debris, silt, and loose soil, ensuring a solid and level foundation. Then, according to the design requirements, the location and dimensions of the toe concrete are accurately determined using measuring instruments and marked.

[0041] Formwork Installation: Install the formwork according to the markings. The formwork should have sufficient strength, rigidity, and stability to ensure that it does not deform during concrete pouring. After the formwork is installed, check its verticality and dimensional accuracy to ensure that it meets the design standards.

[0042] Concrete pouring: High-strength erosion-resistant concrete is used for pouring. During the pouring process, a vibrator is used to fully vibrate the concrete to ensure that it is dense and to avoid defects such as honeycomb and pitting. Pouring should be carried out continuously. If it is necessary to interrupt, the interruption time should not exceed the initial setting time of the concrete.

[0043] Curing: After the concrete is poured, it should be cured promptly. This can be done by covering it with moisture-retaining materials (such as plastic film, straw mats, etc.) and watering it regularly. The curing time should not be less than the specified number of days to ensure the strength and durability of the concrete.

[0044] II. Underwater Slope Protection Construction

[0045] 21. Laying the impermeable geotextile: After cleaning and leveling the slope surface, begin laying the impermeable geotextile. The geotextile should be flat and wrinkle-free, and the overlap width must meet the design requirements, generally not less than a certain distance (e.g., 20cm). Use special fasteners to fix the geotextile to the slope to prevent it from shifting.

[0046] 22. Laying the sand and gravel cushion layer: Lay the sand and gravel cushion layer on the impermeable geotextile. The particle size and gradation of the sand and gravel should meet the design requirements, and the laying thickness should be uniform. It can be laid mechanically or manually. After laying, it should be properly compacted to ensure the density of the cushion layer.

[0047] Laying the hexagonal concrete brick layer 23: Starting from the bottom of the slope, lay the hexagonal concrete bricks sequentially from bottom to top. The bricks should fit tightly together and interlock to ensure that they form a whole protective structure. During the laying process, use tools such as a level to check the flatness and slope of the brick surface at any time to ensure that they meet the design requirements.

[0048] III. Construction of Leisure Trail 3

[0049] Laying the walkway subbase 31: Excavate a foundation trench of a certain depth at the planned walkway location, and fill the trench with compacted sand, gravel, or concrete to form the walkway subbase. Use a road roller or plate vibrator to fully compact the subbase to ensure that its density and flatness meet the design standards.

[0050] 32. Install curb stones on both sides of the walkway. The curb stones should be arranged neatly and at the same height. Use cement mortar to firmly fix the curb stones to ensure their stability.

[0051] Install the walkway joists 33, which are fixed at intervals on the walkway subbase 31. The fasteners of the walkway joists 33 should be anchored to the ground base to ensure the stability of the walkway joists 33.

[0052] 34. Laying Anti-corrosion Wood for the Walkway: Lay anti-corrosion wood on the walkway subbase. The anti-corrosion wood should be of qualified quality and have undergone anti-corrosion treatment. During installation, ensure tight joints and secure fixing. Bolts or specialized connectors can be used for fixing, while ensuring the flatness and aesthetics of the anti-corrosion wood surface.

[0053] IV. Construction of Turf Slope Protection

[0054] Soil improvement: The soil on the slope is improved by adding organic fertilizers and water-retaining agents to enhance its fertility and water retention. The improved soil is then evenly spread over the slope surface to a thickness that meets design requirements.

[0055] Vegetation planting: Select a variety of native flood-tolerant plants for planting, which can be done by sowing grass seeds, cuttings, or transplanting. When planting, pay attention to the spacing and density of the plants to ensure that the vegetation can grow well.

[0056] Maintenance and Management: After the turf slope protection is completed, regular maintenance and management are required. This includes watering, fertilizing, pruning, and pest and disease control to ensure the normal growth and development of the plants and improve the protective and aesthetic effects of the slope protection.

[0057] V. Construction of Sidewalk Structure

[0058] 51. Install sidewalk curbs on both sides of the sidewalk. The curbs should be installed firmly and with straight lines. Use cement mortar for fixing to ensure a tight bond between the curb and the ground.

[0059] 52. Laying a sand cushion layer for the sidewalk: Lay a sand cushion layer for the sidewalk inside the curbstone. The thickness and density of the sand cushion layer should meet the design requirements. Use a plate vibrator to properly compact the sand cushion layer to make its surface smooth.

[0060] 53. Laying Pedestrian Walkway Bricks: Lay the pedestrian walkway bricks on the sand cushion layer according to the design pattern and color. A certain gap should be left between the bricks, and the gaps should be filled with sand or cement mortar to ensure the integrity and stability of the walkway.

[0061] In one embodiment, in order to provide habitat and reproduction for aquatic organisms and promote the balance of the river ecosystem, the hexagonal concrete brick layer 23 is entirely made of solid hexagonal concrete bricks 232, and is equipped with strips made of several hollow hexagonal concrete bricks 231 along the slope direction of the underwater slope 2.

[0062] In one embodiment, in order to ensure that the water at the pedestrian structure 5 can be smoothly discharged into the river, a water pipe 6 is buried in the turf slope 4. The top of the water pipe 6 forms a collection trough at the pedestrian structure 5, and the bottom of the water pipe 6 is at the underwater slope 2.
