Technical Field
[0001] This utility model relates to the field of riverbank reinforcement technology, specifically an ecological revetment for canal bank reinforcement. Background Technology
[0002] The protected objects along the Southern Jiangsu Canal include the central urban areas of Suzhou, Wuxi, and Changzhou, as well as many important towns. It is the most prosperous area in the Taihu Lake Basin and also the most important protected object in the basin.
[0003] The existing canal embankment is mostly composed of masonry retaining walls, with some sections covered by a concrete surface. Due to the age of the existing revetment, although it has been heightened and reinforced multiple times, the reliability of the original wall structure is poor due to the limitations of the construction conditions, construction, and design standards at the time. The overall structure of the existing retaining walls is severely damaged, exhibiting problems such as forward tilting, subsidence, wall damage, leakage, and erosion damage, cracking, and leakage along the bank, posing safety hazards to the retaining walls.
[0004] Furthermore, the current landscape environment of the embankment is poor. Waterfront landscapes and cultural scenic spaces have been encroached upon and blocked by factory buildings, which is incompatible with the requirements for the protection, inheritance, and utilization of the Beijing-Hangzhou Grand Canal World Cultural Heritage. The landscape and cultural elements are dull and empty, lacking vitality. Utility Model Content
[0005] The purpose of this utility model is to provide an ecological revetment for canal bank reinforcement, which solves the problem that the existing retaining wall has serious structural damage after long-term use, such as wall tilting and sinking, as well as leakage, which affects personnel safety.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An ecological revetment for canal bank reinforcement includes: several U-shaped steel sheet piles, which are sequentially connected and installed against the water-facing side of the old revetment wall; the bottom of the U-shaped steel sheet piles is inserted into the soil to a depth twice the height of the U-shaped steel sheet pile above the soil surface; wherein: the two ends of the U-shaped steel sheet piles form curved interlocking buckles, and the middle body is bent to one side to form a U-shape; two adjacent U-shaped steel sheet piles are locked together by interlocking buckles on one side, one facing forward and the other backward; a C35 fine stone concrete filling layer is filled between the U-shaped steel sheet piles and the old revetment wall, the C35 fine stone concrete filling layer covers each U-shaped steel sheet pile facing the old revetment wall and fills and connects the U-shaped steel sheet piles facing the water-facing side into a whole; an L-shaped flower bed retaining wall is anchored to the old revetment wall by several anchor bars; the L-shaped flower bed retaining wall is a reinforced concrete structure, which is cast together with the top of the U-shaped steel sheet piles and the C35 fine stone concrete filling layer.
[0008] Preferably, the L-shaped flower bed retaining wall is located on top of the old revetment wall after the damaged parts have been removed, and is below ground level.
[0009] Preferably, the L-shaped flower bed retaining wall forms a flower bed near the water-facing side and a landscape retaining wall away from the water-facing side.
[0010] Preferably, the flower bed has a drainage pipe inside the water-facing wall, and the water-facing wall is located below the highest navigable water level and above the average water level.
[0011] Ideally, the landscape retaining wall is integrated with the road surface, and a tempered glass transparent wall is installed on top of the landscape retaining wall.
[0012] Ideally, the U-shaped sheet piles should be kept 0.1 meters away from the bottom of the old revetment wall.
[0013] Preferably, the surface of the U-shaped steel sheet pile is coated with an anti-corrosion coating.
[0014] Compared with existing technologies, this utility model uses interlocking U-shaped steel sheet piles to form a single unit, which is then filled with C35 fine aggregate concrete and poured together with the old revetment wall. An L-shaped flower bed retaining wall is then connected to the old revetment wall via anchor bars. This creates a unified structure where the U-shaped steel sheet piles, the old revetment wall, and the L-shaped flower bed retaining wall work together to stabilize and repair the old revetment wall, preventing it from tilting forward. The U-shaped steel sheet piles prevent direct water contact with the revetment, thus avoiding damage, while the L-shaped flower bed retaining wall blocks water erosion from the top, simultaneously enhancing the river landscape.

[0016] Figure 2 This is a schematic diagram of the U-shaped steel sheet pile of this utility model;
[0017] Figure 3 This is a three-dimensional schematic diagram of the present invention. Detailed Implementation
[0018] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.
[0019] like Figure 1 As shown in the embodiment of this utility model, the ecological revetment for canal bank reinforcement includes: several U-shaped steel sheet piles 1, a C35 fine stone concrete filling layer 2, and an L-shaped flower bed retaining wall 3, etc.
[0020] Considering the damage to the original retaining wall, this invention employs several U-shaped steel sheet piles 1 connected to each other in sequence and installed against the water-facing side of the old revetment wall 4 to reinforce the primary retaining wall. Each U-shaped steel sheet pile 1 is 12m long. The bottom of each U-shaped steel sheet pile 1 is inserted into the soil to a depth twice its height above the soil surface, ensuring sufficient stability. The U-shaped steel sheet piles 1 are kept 0.1 meters away from the bottom of the old revetment wall 4, maintaining close contact as much as possible. The surface of each U-shaped steel sheet pile 1 is coated with an anti-corrosion coating.
[0021] See Figure 2 As shown, each end of the U-shaped sheet pile 1 forms a curved locking buckle 11, and the main body in the middle bends to one side to form a U-shape. Two adjacent U-shaped sheet piles 1 are locked together by the locking buckles 11 on one side, one facing forward and the other backward.
[0022] like Figure 1 and Figure 3 As shown, the C35 fine aggregate concrete filling layer 2 is filled between the U-shaped steel sheet piles 1 and the old revetment wall 4. The C35 fine aggregate concrete filling layer 2 covers each U-shaped steel sheet pile 12 facing the old revetment wall 4 and fills and connects each U-shaped steel sheet pile 13 facing the water-facing side into a whole.
[0023] The damaged top structure of the old revetment wall 4 was removed to an elevation of 4.80m, and an L-shaped flower bed retaining wall 3 was installed on top. The L-shaped flower bed retaining wall 3 is located below ground level but above the multi-year average water level. The base plate of the L-shaped flower bed retaining wall 3 is anchored to the old revetment wall 4 by several anchor bars 5. The L-shaped flower bed retaining wall 3 is a reinforced concrete structure, which is connected and poured together with the top of the U-shaped steel sheet piles 1 and the C35 fine aggregate concrete filling layer 2. In this way, the U-shaped steel sheet piles 1, the C35 fine aggregate concrete filling layer 2, the old revetment wall 4, and the L-shaped flower bed retaining wall 3 form a whole, thus working together to protect the stability of the old revetment wall 4. The U-shaped steel sheet piles 1 stand in front of the old revetment wall 4 to prevent water erosion of the old revetment wall 4, while the L-shaped flower bed retaining wall 3 at the top can protect the top of the old revetment wall 4.
[0024] like Figure 3 As shown, an L-shaped flower bed retaining wall 3 forms a flower bed 31 near the water-facing side and a landscape retaining wall 32 away from the water-facing side. A drainage pipe 311 is installed inside the water-facing wall of the flower bed 31, and the water-facing wall is located below the highest navigable water level and above the average water level. The landscape retaining wall 32 is integrally cast with the road surface 6.
[0025] The newly constructed retaining wall has a base slab 0.4m thick and 2.8m wide, a wall body 0.3m thick and 1.7m high, and a side wall of the flower bed on the water-facing side with a body 0.3m thick and 0.6m high. The flower bed 31 is covered with soil and planted with greenery to create a riverside landscape. A tempered glass transparent wall 7 is added to the top of the landscape retaining wall 32, serving as a protective railing. The top of the transparent wall is at an elevation of 7.00m, and a 0.1m high bamboo and wood handrail is installed at the top to meet the flood control standards for the embankment.
[0026] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
