DETAILED DESCRIPTION

[0050] In the following description, specific details are set forth such as particular system configurations, techniques, etc., in order to provide a thorough understanding of the embodiments of the application. However, persons skilled in the art will understand that the application can be practiced without these specific details. In other instances, well-known structures, devices, circuits, and methods have not been described in detail in order to avoid obscuring the description of the application.

[0051] As shown in Figure 1 , the application discloses a composite embankment, which comprises a water blocking module, a business module, a drainage module 18 and a connecting module 6.

[0052] The water blocking module is arranged on the river bank and is used for preventing river water from washing the river bank;

[0053] Preferably, the water retaining module comprises a body unit, a revetment unit 8 and a wave protection unit 1;

[0054] Preferably, the body unit is the main structure of the entire embankment, which is arranged on the river bank and comprises a third number of stable sub-units and a fourth number of reinforcement sub-units 12.

[0055] The third number of stable sub-units are stacked in sequence along the vertical direction on the river bank to form a firm foundation support structure. Each stable sub-unit is made of high-strength and corrosion-resistant materials, such as reinforced concrete or high-performance composite materials, to ensure the stability and durability of the embankment.

[0056] Each reinforcement sub-unit 12 is arranged between adjacent stable sub-units to form an effective reinforcement barrier. In one embodiment, the reinforcement sub-unit 12 is a geogrid made of any of plastic, steel-plastic or glass fiber.

[0057] In the present application, the reinforcement sub-unit 12 has high tensile strength and can effectively constrain the lateral displacement of soil particles, thereby enhancing the self-stability of the body. When the stable sub-unit cannot meet the water retaining requirement, the use of the reinforcement sub-unit 12 can significantly improve the overall stability of the water retaining module, ensuring the safety and reliability of the embankment project.

[0058] The revetment unit 8 is arranged on the water-facing side of the body of the body unit; the revetment unit 8 is made of materials with good anti-erosion performance, such as precast concrete blocks, natural stone or synthetic materials (such as ecological revetment bricks).

[0059] The revetment unit 8 is fixed on the water-facing side of the body unit by embedding or stacking to form a tight and stable protective layer.

[0060] The wave protection unit 1 is arranged on the water-facing side of the top of the body unit and is made of high-strength, lightweight and corrosion-resistant materials, such as aluminum alloy, stainless steel or high-strength synthetic fiber.

[0061] The wave protection unit 1 is connected to the top of the body unit by fixing devices (such as bolts, welding or ropes) to form an effective wave protection barrier.

[0062] The operating module 5 is arranged on the backwater side of the water retaining module for opening operating places according to preset requirements;

[0063] The operating module 5 can include various functional areas such as catering, retail, viewing platform, cultural display, etc. to meet the needs of different groups of people, and its layout design should fully consider factors such as people flow, logistics and safety to ensure the comfort and safety of tourists.

[0064] Preferably, the composite embankment further comprises a protection module 4, a first greening module 3 and a second greening module 7.

[0065] Both the protective module 4 and the first greening module 3 are installed at the top of the embankment unit;

[0066] The protective module 4 is located on the boundary line between the operation module 5 and the embankment unit, and is used to prevent pedestrians from falling; the protective module 4 is at least one of railings, fences, and safety nets.

[0067] The first greening module 3 is located on the side of the protective module 4 facing the embankment unit;

[0068] The second greening module 7 is located inside the slope protection unit 8.

[0069] like Figure 3 As shown, one end of the connecting module 6 is connected to the top of the water-blocking module, and the other end is connected to the operation module 5. It can be any one of a bridge, boardwalk, tunnel, or staircase, and is used to facilitate pedestrian passage between the top of the water-blocking module and the operation module 5.

[0070] The operating module 5 of this invention is a reinforced concrete structure. The design of the operating module 5 not only brings commercial vitality to the area around the dike and increases economic benefits, but also facilitates the passage of pedestrians and vehicles and improves the convenience of regional traffic by connecting it to the top of the water-blocking module through the connecting module 6.

[0071] The drainage module 18 is connected to the operation module 5 and the water-blocking module respectively, and is used to collect rainwater and seepage water inside and outside the dike, and discharge them through the drainage system.

[0072] Preferably, the top of the water-blocking module is provided with a drainage channel for collecting water from the top of the water-blocking module, and the structure of the drainage channel is similar to that of a city's sewer system.

[0073] like Figure 3 As shown, the drainage module 18 is located on one side of the operation module 5 and is connected to the drainage channel. It is used to receive water from the drainage channel and discharge it to a preset location. The drainage module 18 is a drain pipe.

[0074] The protection module 11 is installed between the operation module 5 and the water-blocking module to regulate the water flow and prevent the soil of the water-blocking module and the operation module 5 from being carried away by the water flow. The protection module 11 can be any one of the water flow regulating facilities such as a water flow diffuser or a filter screen.

[0075] Furthermore, the protection module 11 can also divert the water flowing out of the first greening module 3 to prevent the water flowing out of the first greening module 3 from eroding and damaging the top of the water-blocking module and the operation module 5.

[0076] Preferably, the protection module 11 includes a first filter unit, a second filter unit, and a third filter unit arranged sequentially in a direction away from the river water;

[0077] The first, second, and third filtration units are used to filter soil particles of different sizes in the river water, reducing the impact of the river water and thus preventing the soil in the drainage module 18 and the management module 5 from being carried away by the water flow.

[0078] The first filter unit, the second filter unit, and the third filter unit can all be filter screens of preset size or filter layers of preset material.

[0079] When the first, second, and third filter units are all filter screens of a preset size, the first filter unit uses a metal or plastic mesh with a larger pore size, mainly used to filter larger soil particles and impurities; the second filter unit uses a finer filter screen with a smaller pore size, such as a stainless steel filter screen or a high-density polyethylene (HDPE) filter screen, to further filter medium-sized soil particles; and the third filter unit uses an even finer material, such as an activated carbon filter screen or a ceramic filter screen, to filter out tiny soil particles and suspended matter.

[0080] When the first, second, and third filter units are all filter layers made of preset materials, the three filter layers are composed of gravel, sand, or filter media of different particle sizes. Each layer can effectively filter out soil particles of different sizes while allowing water to pass through. Specifically, the first filter unit is composed of large-particle gravel or pebbles, mainly used for the initial filtration of larger soil particles; the second filter unit is composed of medium-particle sand or filter media, used for further filtration of medium-sized soil particles; and the third filter unit is composed of a fine sand layer or filter cloth, used for filtering out tiny soil particles and suspended solids.

[0081] The invention provides multiple filtration units positioned between the management module 5 and the water-blocking module. By observing the water flow rate in the basin, the number and medium of the filtration units can be selected to effectively control the water flow rate and prevent excessive water flow from damaging the management module 5 and the water-blocking module. Furthermore, the filtration units can also filter soil particles from the management module 5 and the water-blocking module, preventing these soil particles from being washed away by the water.

[0082] Preferably, the embankment unit further includes a first isolation subunit and a second isolation subunit 10;

[0083] The first isolation subunit is located between the embankment unit and the protection module 11, mainly serving as an isolation and buffer to reduce mutual influence between the two.

[0084] The second isolation subunit 10 is set between the embankment unit and the slope protection unit 8 to further reinforce the embankment and facilitate the installation and maintenance of the slope protection unit 8.

[0085] Preferably, the composite dike also includes a first number of continuous support modules 16 and a second number of spaced support modules 15;

[0086] The first number of continuous support modules 16 are sequentially installed on the water-facing side of the bottom of the water-blocking module along the riverbank extension direction;

[0087] The second number of interval support modules 15 are arranged between the continuous support module 16 and the riverbank along the riverbank extension direction, and the second number of interval support modules 15 are located at the bottom of the water-blocking module, with a preset distance between adjacent interval support modules 15.

[0088] Both the continuous support module 16 and the spaced support module 15 are columnar structures made of high-strength and durable materials such as reinforced concrete and high-strength steel.

[0089] Preferably, the composite dike also includes a load-bearing module;

[0090] The load-bearing module is connected to the bottom of the water-retaining module and is connected to each continuous support module 16 and each spaced support module 15 respectively. The load-bearing module is a box girder, I-beam, or other structural form with high strength and load-bearing capacity.

[0091] Preferably, the composite dike also includes a cushion layer module 14;

[0092] The cushion layer module 14 is positioned at a preset height between the continuous support module 16 and the spaced support module 15, and the bottom of the cushion layer module 14 is connected to the riverbed. The cushion layer module 14 can be any one of the following: pile front soil, crushed stone cushion layer, geotextile cushion layer, or concrete cushion layer.

[0093] Preferably, the composite dike also includes a monitoring module 26;

[0094] The monitoring module 26 is located on the side of the load-bearing module facing the water surface and is connected to the remote urban flood control center. It is used to monitor the deformation of the dike structure and water level data and feed them back to the urban flood control center to realize the joint commissioning function.

[0095] Preferably, the monitoring module 26 includes multiple deformation monitoring units and multiple water level monitoring units spaced apart along the water flow direction and at preset intervals. Specifically, the number of deformation monitoring units and water level monitoring units is determined by those skilled in the art based on construction requirements, and the two numbers are not necessarily related.

[0096] Preferably, the deformation monitoring unit can be a displacement sensor or a crack sensor, and the water level monitoring unit can be a pressure water level gauge or a float water level gauge.

[0097] This invention uses the data processing system of the urban flood control center to mine and recognize patterns in the monitoring data of the monitoring module 26, providing a scientific basis for flood control decision-making. Specifically, when the monitoring data received by the data processing system shows that the dike structure is deformed or the water level reaches a threshold, an early warning information is automatically triggered, and relevant personnel are notified through various means such as SMS, email, and telephone, thereby activating emergency plans and dispatching disaster relief materials.

[0098] The apparatus of the present invention will be described below with reference to Example 1:

[0099] In Example 1, the first greening module 3 is a flower bed, the stabilizing sub-unit is the embankment layer, the first isolation sub-unit and the second isolation sub-unit 10 are both geotextiles, the reinforcement sub-unit 12 is a polyester geogrid, the slope protection unit 8 is a prefabricated ecological frame slope protection, the protection module 4 is a guardrail, the business module 5 is a row of shops, and the wave protection unit 1 is a wave wall.

[0100] like Figure 1 As shown, the top of the embankment unit is the embankment road 2, which includes a pedestrian walkway and a flood control road. The flower bed is set between the top of the embankment road 2 and the top of the business module 5. The side of the flower bed near the top of the row of shops is equipped with a guardrail. The guardrail consists of multiple posts spaced at preset intervals. Pedestrians can pass through the gaps between the posts to reach the embankment road 2. The setting of the flower bed increases the green area, beautifies the embankment landscape, and also provides a leisure space for the surrounding residents, promoting the harmonious coexistence of man and nature.

[0101] The lower part of the top road 2 is a layered embankment body layer, with geotextiles laid on both sides of the embankment body and polyester geogrids installed between adjacent embankment body layers. This invention effectively enhances the integrity and deformation resistance of the embankment body by laying geotextiles on both sides of the embankment body and installing polyester geogrids between each embankment body layer, thereby improving the stability and durability of the embankment structure.

[0102] The water-facing side of the embankment unit is a prefabricated ecological frame slope protection. The upper and lower layers of prefabricated ecological frame slope protection are connected by bolts. A gravel cushion layer 9 is filled between the prefabricated ecological frame slope protection and the embankment body. Green plants are planted inside the prefabricated ecological frame slope protection.

[0103] The prefabricated ecological frame slope protection in this embodiment not only achieves stability between the upper and lower layers through bolted connections, but also incorporates greenery planted inside, working together with the gravel cushion layer 9 to form a good ecological slope protection system, which helps stabilize the soil, purify the water, and protect biodiversity. Furthermore, the modular multi-layer design of the prefabricated ecological frame slope protection simplifies the construction process, reduces on-site work, improves construction efficiency, and also facilitates later maintenance and replacement.

[0104] Both the continuous support module 16 and the spaced support module 15 are retaining wall piles. For ease of description, the continuous support module 16 is referred to as the water-facing retaining wall pile, and the spaced support module 15 is referred to as the backwater retaining wall pile. The load-bearing module 13 is the capping beam, and the embankment body sits on the capping beam. The capping beam is formed by casting micro-expansion concrete. The bottom adopts a double row of retaining wall piles to form a support structure. The water-facing retaining wall piles are continuous piles. The distance between two adjacent backwater retaining wall piles is 150cm, and the distance between the front and rear rows of retaining wall piles is 300cm.

[0105] The cap beam is formed by casting micro-expansion concrete and combined with the support structure formed by double rows of retaining piles to provide a solid foundation for the dike. In particular, the continuous pile design on the water-facing side further enhances the flood control and disaster resistance capabilities.

[0106] The foundation module 14 is the soil in front of the piles. The height of the soil in front of the piles is determined by the technical personnel according to the construction requirements. The soil in front of the piles is set for the double-row retaining piles. On the one hand, it reduces the amount of earthwork excavation, reduces the construction cost and the impact on the surrounding environment. On the other hand, it facilitates the construction and installation of the cap beam.

[0107] The following are the construction steps of Embodiment 1 of the present invention:

[0108] Step 1: Construct the retaining wall piles at the bottom of the embankment unit.

[0109] In Example 1, as Figure 2 As shown, the retaining wall pile is a prismatic structure with an internal cavity. The water-facing retaining wall pile adopts the static pile-forming process. The water-facing retaining wall pile is a continuous pile, and one side of the cross-section at the top of the retaining wall pile is wavy. Therefore, a gap will be formed between the contact surfaces of adjacent water-facing retaining wall piles. This gap is filled with cement mortar 17.

[0110] After the water-facing retaining wall piles are driven, the water-repellent retaining wall piles are constructed. The driving method is the same as that for the water-facing retaining wall piles. After the piles are driven, the soil in front of the piles is retained and does not need to be completely excavated.

[0111] Step 2: Construction of the capping beam

[0112] The capping beam is made of micro-expansion concrete, and the top of the retaining wall piles extends 20cm into the capping beam. The retaining wall piles are intermittently installed with reinforcing bars that are anchored into the capping beam.

[0113] Step 3: Construction of the Embankment Unit

[0114] After the cap beam reaches the design strength, the embankment body layer is filled with backfill soil in layers according to the design slope ratio. LYGD200 polyester geogrid is set between each layer, with a folded anchorage of ≥120cm. Geotextile is laid on both sides of the embankment body layer.

[0115] Step 4: Construction of prefabricated ecological frame slope protection and greening

[0116] After the embankment unit is completed, the prefabricated ecological frame slope protection is constructed. Each layer of prefabricated ecological frame slope protection is filled with a layer of gravel cushion. The upper and lower layers of prefabricated ecological frame slope protection are connected by bolts. After each layer of prefabricated ecological frame slope protection is filled with boulders and planting soil, green plants are planted.

[0117] Step 5: Construction of row shops, drainage pipes, guardrails, and embankment road 2

[0118] The row of shops is constructed of poured concrete, with guardrails installed near the flowerbeds on the top to prevent pedestrians and vehicles from falling. Drainage pipes are installed at regular intervals on one side of the shops to drain water from the embankment road 2. A walkway leading to embankment road 2 is provided on the other side. The space between the shops and the embankment is vertically filled with three layers of filter material: fine sand, small stones, and large stones, each 20cm thick, from left to right.

[0119] Step Six: Constructing the Flower Bed

[0120] like Figure 4 As shown, the flower bed is an open concrete flower bed 19, with a filter bag 20 and a drainage hole 21 at the bottom.

[0121] Step 7: Construct Embankment Top Road 2 and Wave Wall

[0122] like Figure 5 As shown, the top road 2 consists of a 15cm granite pavement 23, a 10cm 6% cement stone powder slag 24, and a 20cm graded crushed stone cushion layer 25 from top to bottom. First, the wave wall foundation 22 is poured with concrete on the water-facing side of the top road 2, and then the wave wall is installed on the wave wall foundation 22.

[0123] Compared with the prior art, the present invention has the following beneficial effects:

[0124] (1) In this invention, the setting of the operation module makes full use of the space resources on the back side of the dike. The operation module can open operation venues (such as sightseeing, leisure, commerce, etc.) according to preset needs. Therefore, this invention not only achieves flood control safety, but also improves the economic benefits of the dike and increases land use efficiency.

[0125] (2) By integrating the water-blocking module, the operation module, the drainage module and the connection module, the present invention forms a multifunctional composite dike. The water-blocking module effectively blocks the river water from eroding and ensures the safety of the riverbank. The drainage module efficiently guides the water flow from the top of the water-blocking module and the operation module area to a preset location, avoiding direct damage to the dike structure and the operation site by the water body, and greatly enhancing the overall protection capability of the dike.

[0126] (3) In this invention, the protection module not only regulates water flow and prevents soil erosion, but also helps to maintain the ecological balance around the dike and reduce soil erosion. It is of great significance to protect the ecological environment of the riverbank. At the same time, this design reduces the environmental damage that may be caused by traditional dike construction and embodies the concept of green dike.

[0127] (4) In this invention, the design of the connecting module cleverly connects the top of the water-blocking module with the operation module, providing a convenient passage for pedestrians and enhancing the accessibility and interactivity of the dike area. This not only facilitates the daily activities of residents, but also ensures the safety of personnel evacuation in emergency situations.

[0128] (5) Through reasonable modular design, the present invention makes the maintenance of composite dikes easier. Each module can be inspected and replaced independently, reducing the overall maintenance cost. At the same time, the present invention sets up an efficient drainage system to ensure the long-term stability and service life of the dikes, providing strong support for the sustainable development of the social economy.
