Description

Technical Field

[0001] This utility model relates to the field of ecological ditch technology, specifically to an ecological ditch for highway networks suitable for mountainous ecological zones. Background Technology

[0002] Ecological ditches are an environmentally friendly type of ditch that eliminates a large amount of masonry work and replaces it with greenery, while also effectively solving drainage problems.

[0003] Currently, the cross-sections of ditches in my country mainly take the forms of trapezoids, triangles, rectangles, and streamlines. The cross-sections of drainage ditches and intercepting ditches are mainly trapezoidal. The main protection types include earthen ditch compaction reinforcement, three-component or four-component soil reinforcement, single-layer dry-laid rubble reinforcement, single-layer pebble reinforcement, mortar-laid rubble reinforcement, and cement concrete precast block protection. In general, engineering protection is the main focus. However, many ditches in the existing technology suffer from serious siltation, blockage, and subsidence due to factors such as inadequate length, incomplete foundation treatment, lack of proper protection of the ditch body, excessively long outlet spacing, improper end design, and untimely maintenance. This renders the ditches ineffective, and excessive water seeps into the roadbed, causing roadbed subsidence and ultimately affecting the road surface and the normal operation of the highway.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] An ecological ditch for road networks suitable for mountainous ecological zones includes a slope 1. A slope bottom platform 2 is fixedly connected to the outer side of the bottom of the slope 1. A three-dimensional mesh 3 is provided on the front side of the slope bottom platform 2. Plants such as bermudagrass, rhododendron, and Canadian fern are typically planted in the grooves and secured with the three-dimensional mesh 3. A reinforced coconut fiber mat 31 is laid on the surface of the three-dimensional mesh 3 and fixed to the soil surface where grass is sprayed, forming a continuous surface where grass roots, vegetation mat, and soil are combined. This slows down the water flow, reduces the impact of water flow on the ditch, prevents soil erosion, and increases the vegetation coverage. To improve the survival rate, natural coconut fiber mat 31 is embedded on its surface with natural coconut columns 32, which are covered with coconut fiber mesh or geonet. This provides a secure root support system for the plants and has a high water absorption and storage capacity. This material will automatically weather into organic matter after 4-10 years, increasing soil fertility, promoting plant growth, and meeting clean production requirements, thus realizing the concepts of ecology and environmental protection. The lower part of the three-dimensional mesh 3 is filled with backfill soil 4 to ensure vegetation growth. The outer edge of the backfill soil 4 is fixedly connected to a road shoulder 10. The external shoulder 10 is fixedly connected to the public road 12. A gravel layer 5 is filled under the backfill soil 4. A permeable geotextile 11 is lined the outer edge of the gravel layer 5, ensuring normal drainage while improving the stability of the ditch. A concrete support frame base plate 6 is fitted over the gravel layer 5. Concrete support frame side plates 61 are movably connected to the surface of the concrete support frame base plate 6. A first insertion block 62 and a second insertion block 63 are fixedly connected to the upper surface of the concrete support frame base plate 6. The lower surface of the side plate 61 is provided with a slot 64, which makes the concrete receiving frame in this new type easy to transport and assemble on site. Moreover, when the concrete receiving frame does not match the actual site conditions, its size can be changed to facilitate its adaptation to the side ditch. The bottom of the concrete receiving frame base plate 6 is covered with a volcanic rock layer 7. The crushed stone layer 5, the concrete receiving frame base plate 6 and the volcanic rock layer 7 serve as the foundation and ensure normal drainage. The bottom of the outer side of the concrete receiving frame base plate 6 is covered with a crushed stone blind ditch 8. The interior of the crushed stone blind ditch 8 is covered with a flexible permeable pipe structure 9, which is used for underground drainage.

[0024] Furthermore, the three-dimensional mesh 3 is recessed downwards, and the natural coconut column 32 is embedded in the three-dimensional mesh 3. The groove formed by the three-dimensional mesh 3 is 40cm deep. Plants such as bermudagrass, azalea and Canadian fern are usually planted in the groove, and the plants are fixed with the three-dimensional mesh 3.

[0025] Furthermore, the natural coconut columns 32 protrude about 5cm above the ground, with a 5-meter interval between the two sets of natural coconut columns 32. The natural coconut columns 32 are cylindrical bodies made of natural pure coconut fiber, and are covered with coconut fiber mesh or geonet, which can provide a fixed and safe root support system for plants and has a high water absorption and storage capacity. This material will automatically weather into organic matter after 4 to 10 years, which not only increases soil fertility and promotes plant growth, but also meets the requirements of clean production, realizing the concept of ecology and environmental protection.

[0026] Furthermore, the backfill soil 4 is used to ensure the growth of vegetation. The volcanic rocks in the volcanic rock layer 7 have a uniform particle size of 20-30mm. The filling thickness of the volcanic rock layer 7 is about 25cm. The permeable geotextile 11 ensures normal drainage while improving the stability of the side ditch.

[0027] Furthermore, the gravel in the gravel layer 5 has a particle size of 30-40mm, and the filling thickness of the gravel layer 5 is 30cm. The gravel layer 5, the concrete support frame base plate 6, and the volcanic rock layer 7 serve as the foundation while ensuring normal drainage. The flexible permeable pipe structure 9 is used for underground drainage.

[0028] Furthermore, the reinforced coconut fiber mat 31 is composed of three layers of reinforced polypropylene mesh and a single layer of reinforced coconut fiber. The reinforced coconut fiber mat 31 has a high porosity and ideal elasticity. The reinforced coconut fiber mat 31 is fixed to the soil surface of the sprayed grass, forming a continuous surface where grass roots, vegetation mat and soil are combined. This can slow down the water flow speed, reduce the impact of water flow on the ditch, prevent the soil from being washed away by water, and improve the survival rate of plants on the eroded surface.

[0029] Furthermore, both the first plug-in block 62 and the second plug-in block 63 are block-shaped. The side plate 61 of the concrete receiving frame is plugged into the bottom plate 6 of the concrete receiving frame through the first plug-in block 62, the second plug-in block 63 and the plug-in groove 64, which makes the concrete receiving frame in this new type convenient for transportation and on-site assembly. Moreover, when the concrete receiving frame does not match the actual site conditions, its size can be changed to facilitate its adaptation to the side ditch.

[0030] Working principle: For drainage ditches longer than 200 meters, a row of native plants is planted 50 cm apart on both sides of the rectangular ditch, with a planting spacing of one meter. Grass seeds are first sprayed on the outside of the rectangular ditch, and then reinforced coconut fiber blankets 31 are laid. Every 5 meters, a natural coconut column 32 is buried and fixed with iron nails. The natural coconut column 32 protrudes about 5 cm above the ground. Then, cement is poured to form a concrete support frame for the ditch. Then, volcanic rock with a uniform particle size of 20-30 mm is selected to fill the bottom of the ditch to a thickness of about 25 cm. Then, crushed stone with a particle size of 30-40 mm is filled to a thickness of 30 cm. Then, topsoil is used for backfilling, leaving a 40 cm deep groove. Bermuda grass, azalea, and Canadian fern are planted in the groove. The plants are fixed with a 3D mesh 3. After the plants grow to a certain height, water samples from the control ditch and the treated ditch are collected on a rainy day to analyze the effect.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
