Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, and more specifically, to a combined ecological bank protection structure. Background Technology

[0002] Current river management technologies primarily utilize rigid structures such as masonry and concrete retaining walls. While these structures offer high stability, they hinder the exchange of matter and energy between the water and the banks, severing the connection between the aquatic and terrestrial ecosystems. This leads to habitat loss and landscape stagnation, which is detrimental to ecological balance. Furthermore, the structures are complex, and the artificiality of the bank protection is excessive. Utility Model Content

[0003] This utility model proposes a combined ecological bank protection structure, the purpose of which is to provide an ecological bank protection that maintains the connection between water and shore, with a simple and natural structure.

[0004] A combined ecological revetment structure includes: a pile foundation structure, which is densely and vertically inserted into the riverbed foundation; a precast slotted guide beam with an "n"-shaped cross-section, including a slot with an open bottom and a top platform, and the outer side of the top platform is provided as a protruding sill; the slot is installed on the top of the pile foundation structure and the contact surface is filled with rubber strips; a planting platform is located on the water-facing side of the precast slotted guide beam, and the planting platform is lower than the precast slotted guide beam; the planting platform is designed for a low water level and is 20cm lower than the normal water level; emergent plants are planted on the planting platform; and a solidified soil slope protection, which is laid diagonally upward along the top platform to the top of the embankment and planted with greenery; the top of the solidified soil slope protection is higher than the designed high water level.

[0005] Preferably, the slope ratio of the solidified soil slope protection is set in the range of 1:2-1:3, and the thickness of the solidified soil layer needs to be ≥30cm.

[0006] Preferably, the prefabricated slotted guide beam has a height of 50cm and a width of 40-50cm; the protruding sill has a width of 20cm; and the slot and the top of the pile foundation structure have an embedding length of 25cm and a width of 20cm-25cm.

[0007] By adopting the above technical solution, the combined revetment structure of this utility model, which uses a combination of precast piles, slotted guide beams and solidified soil slope protection, not only meets the requirements for the stability of riverbanks, but also provides habitats and breeding grounds for fish and amphibians, maintains the connection between the water and the shore, has a simple structure, fewer artificial traces, and is more natural. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the combined ecological bank protection structure of this utility model; Figure 2 This is a schematic diagram of a prefabricated guide beam structure. Detailed Implementation

[0009] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0010] See Figure 1 The diagram shown is a structural schematic of the combined ecological revetment structure of this utility model. In this embodiment, the combined ecological revetment structure includes a planting platform 1, a pile foundation structure 2, a prefabricated slotted guide beam 3, a stabilized soil slope protection 5, and rubber strips 4.

[0011] The pile foundation structure consists of two closely spaced, vertically inserted piles into the riverbed foundation. The piles are a type of precast reinforced concrete square pile, imitation wood pile, sheet pile, or steel sheet pile.

[0012] Combination Figure 1 and Figure 2 As shown, the precast slotted guide beam 3 is a reinforced concrete structure. The cross-section of the precast slotted guide beam 3 is "n"-shaped. The precast slotted guide beam 3 includes a slot 31 with an open bottom and a top platform 32, and the outer side of the top platform 32 is provided with a protruding sill 33. The slot 31 is installed on the top of the pile foundation structure 1 and the contact surface is filled with rubber strips 4 to ensure the stability of the installation. Preferably, the height of the precast slotted guide beam is 50cm and the width is 40-50cm; the width of the protruding sill is 20cm; the embedment length of the slot and the top of the pile foundation structure is 25cm and the width is 20cm-25cm.

[0013] The planting platform 1 is located on the water-facing side of the prefabricated slotted guide beam 3. The planting platform is lower than the prefabricated slotted guide beam 3. The planting platform 1 is designed for a low water level, 20cm below the normal water level, so that the planting platform 1 is below the water surface. Ornamental emergent plants 7 are generally planted on the platform, providing a platform for benthic animals and amphibians to inhabit, reproduce, overwinter, and enter and exit the water.

[0014] The solidified soil slope protection 5 is laid diagonally upwards from the top platform 32 to the top of the embankment 6, and greenery is planted to prevent soil erosion. Raised edges 33 prevent the solidified soil slope protection 5 from sliding down. The slope ratio of the solidified soil slope protection is set within the range of 1:2-1:3, and the thickness of the solidified soil layer must be ≥30cm. The top of the solidified soil slope protection is higher than the design high water level. Under normal water levels, the solidified soil slope protection can also provide a platform for benthic and amphibious animals to inhabit, breed, overwinter, and access water and land.

[0015] The entire modular aquatic ecological revetment has fewer hardened structures, is simple in design and easy to operate, and blends more closely with the natural landscape after completion, providing more living space for benthic and amphibious animals. The pile foundation structure and precast guide beams are all set below the normal water level, meeting the stability requirements of the riverbank slope and effectively preventing soil erosion. The precast piles and guide beams are economically efficient, of stable quality, easy to install, and have a short construction period. Meanwhile, the planting platform in front of the piles and the solidified soil on the guide beams are integrated with the revetment structure, providing conditions for fish and amphibians to inhabit, reproduce, overwinter, and enter and exit the water, promoting biological migration and dispersal.

[0016] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of this utility model. All equivalent changes and modifications made to this utility model by those skilled in the art should fall within the scope of the appended claims.
