Abstract
Description
Technical Field
[0001] This application relates to the field of riverbank protection construction technology in mountainous areas, specifically to an ecological riverbank protection structure applied to mountainous rivers. Background Technology
[0002] Mountain rivers experience rapid formation of torrential rain runoff and short confluence time, resulting in flash floods and extreme fluctuations in water level and flow. Due to the large longitudinal gradient and high flow velocity of these rivers, traditional riverbank protection projects in mountainous areas mostly employ hard revetments with structures such as masonry, concrete, or precast concrete. These revetment forms are simple in structure, have poor landscape effects, and are costly. At the same time, they damage the original ecosystem of mountain rivers, and hard revetments are completely incompatible with the natural landscape style of mountainous areas.
[0003] The rapid development of ecological revetment has injected new vitality into mountain rivers. Most existing ecological revetments adopt a combination of gabion stone cages for toe protection and slope protection. However, mountain rivers have fast flow rates and carry a large number of boulders and pebbles, which makes it impossible to meet the erosion resistance requirements. Hard structures such as concrete and masonry can meet the erosion resistance requirements, but they have poor aesthetic appeal. Utility Model Content
[0004] The purpose of this application is to provide an ecological revetment structure for use in mountainous rivers, which improves the landscape effect and ecological nature of mountainous rivers while ensuring the stability of the revetment for flood control and erosion resistance.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] This application provides an ecological revetment structure for use in mountainous river channels, including pine piles set at the bottom of the river channel, a concrete base set on the bank side of the pine piles, a precast reinforced concrete vegetation frame set on the concrete base, backfilling the bank side of the precast reinforced concrete vegetation frame with backfill soil, a concrete platform set on the backfill soil, and a cast-in-place masonry slope protection connected above the concrete platform, which is then connected to the ecological vegetation concrete slope protection.
[0007] The pine pile is embedded 1.5m into the foundation and rises at least 0.2m above the concrete base.
[0008] The precast reinforced concrete planting frame includes a planting frame body, within which ecological planting concrete is provided, and emergent plants are planted within the ecological planting concrete.
[0009] The concrete platform comprises, from bottom to top, an artificial base layer, a cement-stabilized crushed stone base layer, and a concrete platform layer, with the artificial base layer laid on top of the backfill soil.
[0010] The ecological vegetated concrete slope protection includes a geotextile at the bottom of the structure, a layer of recycled aggregate on the geotextile, a layer of ecological vegetated concrete on the recycled aggregate, and a planting layer on the ecological vegetated concrete, with seeds and seedlings sown inside the planting layer.
[0011] Compared with the prior art, the beneficial effects of this application are: This utility model solves the shortcomings of mountain rivers, such as fast flow velocity, carrying a large amount of gravel and pebbles, easy erosion and collapse of riverbanks, and the neglect of landscape effect and disharmony between traditional hard revetment structures and the natural environment. Through the structural combination of pine piles, concrete bases, precast vegetation frames, concrete platforms, vegetation slope protection and greening planting, a mountain river revetment structure is formed that stabilizes the river channel, improves the boundary conditions of the river flow, effectively prevents the erosion of the mountain river flow, prevents the collapse and sliding of the riverbank, greens and beautifies the environment, and improves the landscape effect of the mountain river. It can effectively stabilize the slope and prevent the bank erosion. Attached Figure Description
[0012] To more clearly illustrate the technical solutions of the embodiments of this application, the accompanying drawings used in the embodiments of this application will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation of the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0015] Figure 3 A schematic diagram of an ecologically vegetated concrete slope protection structure. Detailed Implementation
[0016] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0017] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0018] like Figures 1-3 As shown in the embodiment of this application, an ecological revetment structure for mountain rivers is provided, including pine piles 1 set at the bottom of the river, a concrete base 2 set on the bank side of the pine piles 1, a precast reinforced concrete vegetation frame 3 set on the concrete base 2, backfilling the bank side of the precast reinforced concrete vegetation frame 3 with backfill soil 4, a concrete platform 5 set on the backfill soil 4, a cast-in-place masonry slope protection 6 connected above the concrete platform 5, and an ecological vegetation concrete slope protection 7 connected to the cast-in-place masonry slope protection 6.
[0019] Specifically, in mountainous river channels with high flow velocities below the normal internal water level H2, the combination of pine piles 1, concrete base 2, and precast reinforced concrete vegetation frame 3 can effectively improve the erosion resistance of the revetment. The pine piles 1 are embedded 1.5m into the foundation and extend at least 0.2m above the concrete base 2, effectively shielding the concrete base and providing a certain aesthetic effect. The concrete base 2 is located at the bottom of the precast reinforced concrete vegetation frame 3, which contains ecological vegetation concrete 3.2 and emergent plants 3.3. The superposition of these two elements enhances the self-weight of the revetment, further ensuring the stability of the revetment structure. Simultaneously, the high flow velocity and rapid erosion in mountainous river channels make traditional fill materials susceptible to severe erosion, hindering plant survival. The ecological vegetation concrete 3.2 within the precast reinforced concrete vegetation frame 3 effectively improves plant survival rates.
[0020] Specifically, mountainous river channels have short confluence times, rapid flood rises and falls, and extreme fluctuations in water level and flow. Between the highest controlled water level H3 and the normal internal water level H2, the time for water erosion is relatively short, resulting in weaker requirements for bank protection erosion resistance. Setting the masonry slope protection 6 between the highest controlled water level H3 and the normal internal water level H2 effectively ensures bank stability. The masonry slope protection 6 connects to the ecological vegetation concrete slope protection 7, such as... Figure 3 The ecological vegetated concrete slope protection 7 shown is composed of geotextile 7.1, recycled aggregate layer 7.2, ecological vegetated concrete layer 7.3, and planting layer 7.4. The planting layer 7.4 is planted with seedlings and seeds 7.5 to improve the landscape effect and water accessibility of the ecological bank protection.
[0021] Lower the river water level within the revetment construction area, and determine the position and elevation of pine pile 1 and concrete base 2 by surveying and setting out.
[0022] Precast reinforced concrete planting frame 3 according to Figure 1 As shown, the superposition is performed, and the superposition height is equal to or higher than the normal internal water level H2.
[0023] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
