AI Technical Summary
River embankments in high-density urban areas usually use water-impermeable hardened embankments, which lead to damage to the ecology and landscape functions of the river and is difficult to construct. Especially in an environment with narrow rivers and high-rise buildings, the construction of traditional ecological embankments involves difficulties in land acquisition and demolition.
The ecological block bank protection is combined with the embankment bearing structure, and the anti-shock bottom plate and filler body are used, and the load-bearing piles such as mechanical cast-injected piles and high-pressure rotary spray piles are combined to form a stable ecological embankment structure, taking into account the river ecology and landscape effects.
It has achieved the restoration of the river ecological landscape function without affecting the existing buildings, reducing construction difficulty and saving costs, and ensuring the stability and water permeability of the embankment structure.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to an ecological bank structure for urban high-density areas. Background Art
[0002] With the continuous construction of modern cities in China, the space of many urban rivers has been continuously occupied. In particular, the living space of water bodies in high-density built-up areas has been extremely squeezed, and the available space for urban river banks is narrow. Therefore, many hardened river banks have been formed in high-density built-up areas. At present, the common hardened bank types for narrow urban rivers include: gravity retaining walls, cantilever retaining walls, pile retaining walls, etc. Among them, the pile retaining wall is widely used in the design of narrow urban river banks due to its small land occupation space and less involvement in land expropriation and demolition. It can be used as both a temporary support during construction and a permanent structure. However, the structural material of the pile retaining wall is impermeable itself, blocking the water vapor exchange between the river and both banks and damaging the ecological and landscape functions of the river. At the same time, there are many high-rise buildings around the rivers in urban high-density areas, with limited construction space and great construction difficulty. If a traditional natural ecological bank is adopted, it will involve land expropriation and demolition, with great handling difficulty. Summary of the Utility Model
[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide an ecological bank structure for urban high-density areas, which can solve the problem that the hardened impermeable banks that usually damage the ecological and landscape functions of urban narrow rivers are commonly used.
[0004] To this end, the utility model adopts the following technical solutions:
[0005] An ecological bank structure for urban high-density areas includes bank bearing structures on both sides of the river. On the side of the bank bearing structure close to the river, there is an anti-scour bottom plate. The lower part of the anti-scour bottom plate is located in the riverbed, and several ecological block revetments are stacked on the upper surface of the anti-scour bottom plate. There is a filling body between the ecological block revetment and the bank bearing structure.
[0006] On the basis of adopting the above technical solutions, the utility model can also adopt the following further technical solutions, or use these further technical solutions in combination:
[0007] The bank bearing structure includes several first bearing piles arranged along the extension direction of the river. On the side of the first bearing pile close to the river, there are several second bearing piles. The first bearing piles and the second bearing piles are arranged at intervals. The filling body includes graded gravel, and the graded gravel is filled between the bank bearing structure and the ecological block revetment.
[0008] There is a capping beam on the first bearing pile and the second bearing pile.
[0009] The first bearing pile is a mechanical cast-in-place pile, and the second bearing pile is a high-pressure jet grouting pile.
[0010] The diameter of the second bearing pile is greater than that of the first bearing pile. The distance between two adjacent first bearing piles is less than the diameter of the second bearing pile. The second bearing pile is located on one side of the first bearing pile and they are in contact with each other. The vertical center distance between the first bearing pile and the second bearing pile is greater than the radius of the second bearing pile and less than the diameter of the second bearing pile.
[0011] The bank bearing structure includes steel sheet piles arranged along the extending direction of the river course. The filling body includes graded gravel and earth backfill. The graded gravel and the earth backfill are filled between the steel sheet piles and the ecological block revetment. The earth backfill is located on the side of the steel sheet piles close to the river course, and the graded gravel is located between the earth backfill and the ecological block revetment.
[0012] The bank bearing structure further includes steel sheet piles arranged along the extending direction of the river course. The steel sheet piles are located on one side of the river course, and the first bearing pile and the second bearing pile are located on the other side of the river course. The filling body further includes earth backfill. The graded gravel and the earth backfill are filled between the steel sheet piles and the ecological block revetment. The earth backfill is located on the side of the steel sheet piles close to the river course, and the graded gravel is located between the earth backfill and the ecological block revetment.
[0013] The ecological block revetment is a box-shaped block.
[0014] The upper surface of the ecological block revetment flush with the bank is provided with a coping, and a landscape railing is fixed on the coping.
[0015] The ecological block is provided with backfill soil and plant seeds.
[0016] Compared with the prior art, the utility model has the following advantages and beneficial effects: The structure of the utility model is simple, the construction is convenient, it is safe and reliable and the cost is low. By setting the bank bearing structure and the anti-scour bottom plate, the structural stability of the bank is ensured; By setting the box-shaped ecological block revetment, the ecological and landscape effects of the river course are increased. It can not only ensure the flood discharge and drainage functions of the river course, but also restore the ecological landscape and other functions of the river course, and does not affect the existing buildings in the high-density urban area. At the same time, it can also save costs and reduce the construction difficulty. Description of the Drawings
