[0001] The present invention relates to the technical field of bridge embankment protection, and in particular to a gravity-type bridge embankment protection structure and an assembly method thereof. Background Art

[0002] A gravity bridge embankment refers to an embankment structure that relies on its own weight to maintain its anti-tilting and anti-sliding stability. It is mainly composed of walls, superstructures and base beds. It is usually used for the protection and reinforcement of bridges to ensure the safety and stability of bridges and their surrounding areas. Gravity bridge embankments can effectively resist erosion and damage from natural factors such as wind, waves and water flow. Compared with other types of embankment structures, the construction process of gravity bridge embankments is relatively simple.

[0011] Preferably, the cross-section of the arc baffle is set to be semi-elliptical, and the arc baffle is sleeved on the outer surfaces of two adjacent water-dividing tips. Three second reserved holes are evenly spaced on both sides of the outer surface of the water-dividing tip, and the positions of the second reserved holes correspond to the positions of the second mounting holes and are connected to each other.

[0012] Preferably, the second connecting bolt passes through the inner cavity of the second reserved hole and the second mounting hole, and second fastening nuts are threadedly connected to both sides of the outer surface of the second connecting bolt.

[0013] Preferably, the middle part of one end of the embankment body away from the fixing assembly is arranged in an arc shape, and the upper and lower ends of the embankment body are respectively provided with a reinforcement layer and a crushed stone layer.

[0014] The present invention also provides an assembly method of a gravity bridge embankment structure, comprising the following steps: Step 1: according to the specific conditions of the bridge, several berm bodies are spliced ​​together, and two adjacent water diversion tips are also spliced ​​together. Then, at the end of the berm body away from the water diversion tip, steel cables are evenly laid according to the position of the first reserved hole. After the laying is completed, a fastening assembly is installed in the inner cavity of the first reserved hole, and the fixing plate is installed according to the position of the first reserved hole, so that the positions of the first reserved hole and the first installation hole correspond to each other; Step 2: After the positions of the steel cable and the fixing plate are determined, the first connecting bolt is passed through the inner cavities of the first mounting hole and the first reserved hole, and inserted into the inner cavity of the connecting groove of the inner cavity of the connecting column, and then the first fastening nut is rotated, so that the fixing plate squeezes and fixes the steel cable through the rotation of the first fastening nut; Step 3: When the first connecting bolt is tightened through the first fastening nut, it will continuously squeeze into the inner cavity of the first reserved hole.

[0015] Technical effects and advantages of the present invention: The present invention provides a levee body with an arc-shaped structure. The arched design in the middle can effectively disperse the pressure and improve the overall stability of the levee body. At the same time, the water diversion tip structure at one end of the levee body can effectively resist the impact and scouring of the water flow and disperse the impact force of the water flow on the levee, thereby improving the overall stability of the levee and helping to slow down the water flow speed and reduce the scouring and erosion of the soil on both sides of the levee by the water flow.

[0016] The present invention assembles multiple embankment bodies by providing a fixing component. According to the specific conditions of the bridge river channel, several prepared embankment bodies are spliced ​​together. Since the upper and lower ends of the embankment body are respectively provided with a reinforcement layer and a gravel layer, they are reinforced by the fixing component. At the same time, the two embankment bodies are reinforced by the fixing component, so that the steel cable is fixed as a whole. Several embankment bodies are firmly connected together by binding to form a stable overall structure. The first reserved hole and the first mounting hole determine the installation position of the fixing component, and a fastening component is added to the inner cavity of the first reserved hole. The first connecting bolt is maintained in a predetermined position by the reverse force generated by the compression of the fastening spring therein, and when the first connecting bolt and the first fastening nut are tightened, the elastic part of the spring washer will be compressed, thereby generating a force to resist loosening, preventing the first connecting bolt or the first fastening nut from loosening under vibration or other stresses, thereby improving the tightness of the connection between the fixing component and the embankment body.

[0017] The present invention protects the water-dividing tip structure by providing a protection component. Since the structure at the water-dividing tip is relatively thin and a certain gap is generated between two adjacent water-dividing tips, the gap will continue to expand under the impact of the water flow. The arc-shaped baffle plate is used to prevent the connection between the water-dividing tips from being impacted by the water flow, which would cause the structure to be damaged. The semi-arc design can protect it while ensuring the dispersion of the water flow, and at the same time play a certain buffering role. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Further, such as Figure 3 and Figure 4 As shown, the position of the first reserved hole 5 corresponds to the position of the first mounting hole 62 and they are connected, the fastening component 64 is located in the inner cavity of the first reserved hole 5, the first connecting bolt 63 passes through the first mounting hole 62 and the inner cavity of the first reserved hole 5, and the installation position of the fixing component 6 is determined by the first reserved hole 5 and the first mounting hole 62. When several embankment bodies 1 are spliced, the fixing component 6 is installed in the middle part and the connection of the embankment body 1 for fixing.

[0029] Further, such as Figure 3 As shown, the outer surface of the first connecting bolt 63 is sleeved with a reinforcing gasket 65 and a spring washer 66, and the outer surface of the first connecting bolt 63 is threadedly connected with a first fastening nut 67, and the spring washer 66 is located between the reinforcing gasket 65 and the first fastening nut 67. The reinforcing gasket 65 and the spring washer 66 provide additional fastening force. When the first connecting bolt 63 and the first fastening nut 67 are tightened, the elastic part of the spring washer 66 will be compressed, thereby generating a force to resist loosening, preventing the first connecting bolt 63 or the first fastening nut 67 from loosening under vibration or other stresses, thereby improving the tightness of the connection between the fixing assembly 6 and the embankment body 1.

[0030] Further, such as Figure 4 and Figure 5 As shown, the fastening assembly 64 includes a fastening spring 641 arranged in the inner cavity of the first reserved hole 5, and the end of the fastening spring 641 close to the fixing plate 61 is fixedly connected to a connecting block 642, and the middle part of the connecting block 642 is fixedly connected to a connecting column 643, and the inner cavity of the connecting column 643 is provided with a connecting groove 644.

[0031] Further, such as Figure 4 and Figure 5 As shown, the connecting block 642 is movably connected to the inner cavity of the first reserved hole 5, the position of the first connecting bolt 63 corresponds to the position of the connecting column 643, the first connecting bolt 63 passes through and is movably connected to the inner cavity of the connecting through groove 644, when the first connecting bolt 63 is continuously screwed into the inner cavity of the connecting through groove 644, the fastening spring 641 is compressed, when the first connecting bolt 63 is screwed in to a certain extent, the fastening spring 641 is no longer compressed, thereby generating a force in the opposite direction, so that the first connecting bolt 63 remains in a predetermined position.

[0032] Further, such as Figure 1 As shown, a steel cable 7 is arranged between the fixing plate 61 and the embankment body 1. After the embankment body 1 is spliced, the steel cable 7 is evenly laid according to the position of the first reserved hole 5. The first connecting bolt 63 passes through the middle of the steel cable 7. The steel cable 7 is fixed into a whole by the fixing assembly 6. The steel cable 7 is used as a high-strength connecting component, and several embankment bodies 1 are firmly connected together by binding to form a stable overall structure.

[0033] Further, such as Figure 2 and Figure 6 As shown, the cross section of the arc baffle 91 is set to be semi-elliptical, and the arc baffle 91 is sleeved on the outer surfaces of two adjacent water-dividing tips 4. When the two adjacent water-dividing tips 4 are spliced ​​together, a certain gap will be generated, and the structure at the water-dividing tip 4 is relatively thin. Under the impact of the water flow, the gap will continue to expand and cause certain damage. The arc baffle 91 can prevent the connection between the water-dividing tips 4 from being impacted by the water flow, causing the structure to be damaged. The semi-arc design can protect it while ensuring the dispersion of the water flow, and at the same time play a certain buffering role. Three second reserved holes 8 are evenly spaced on both sides of the outer surface of the water-dividing tip 4, and the position of the second reserved hole 8 corresponds to the position of the second mounting hole 92 and is connected and communicated.

[0035] Further, such as Figure 1 As shown, the middle part of one end of the embankment body 1 away from the fixing assembly 6 is arranged in an arc shape. The arched design of the middle part of the embankment body 1 can effectively disperse the pressure and improve the overall stability of the embankment body 1. The upper and lower ends of the embankment body 1 are respectively provided with a reinforcement layer 2 and a gravel layer 3. Suitable aquatic plants can be planted above the reinforcement layer 2, which can absorb pollutants in the water, thereby reducing the pollution load of the water body. The gravel layer 3 can effectively disperse the pressure of water flow, waves or ground water bodies, reduce the direct impact on the soil layer at the bottom of the embankment, thereby enhancing the overall stability of the embankment.

[0036] A method for assembling a gravity bridge embankment structure comprises the following steps: Step 1: according to the specific conditions of the bridge, several berm bodies 1 are spliced ​​together, and two adjacent water diversion tips 4 are also spliced ​​together. Then, at the end of the berm body 1 away from the water diversion tip 4, the steel cable 7 is evenly laid according to the position of the first reserved hole 5. After the laying is completed, the fastening component 64 is installed in the inner cavity of the first reserved hole 5, and the fixing plate 61 is installed according to the position of the first reserved hole 5, so that the positions of the first reserved hole 5 and the first installation hole 62 correspond. The fixing component 6 is fixed to the middle part of the berm body 1 and the connection between every two berm bodies 1 to ensure the stability and firmness of the connection between the berm bodies 1, and at the same time ensure the firmness of the reinforcement layer 2 and the gravel layer 3 set at the upper and lower ends thereof; Step 2: After the positions of the steel cable 7 and the fixing plate 61 are determined, the first connecting bolt 63 is passed through the inner cavity of the first mounting hole 62 and the first reserved hole 5, so that it is inserted into the inner cavity of the connecting groove 644 of the inner cavity of the connecting column 643, and then the first fastening nut 67 is rotated. Through the rotation of the first fastening nut 67, the fixing plate 61 squeezes and fixes the steel cable 7. A reinforcing gasket 65 and a spring washer 66 are added between the first fastening nut 67 and the fixing plate 61. The reinforcing gasket 65 and the spring washer 66 provide additional fastening force. When the first connecting bolt 63 and the first fastening nut 67 are tightened, the elastic part of the spring washer 66 will be compressed, thereby generating a force to resist loosening, preventing the first connecting bolt 63 or the first fastening nut 67 from loosening under vibration or other stresses, thereby improving the tightness of the connection between the fixing assembly 6 and the embankment body 1; Step 3: When the first connecting bolt 63 is tightened by the first fastening nut 67, it will continuously squeeze into the inner cavity of the first reserved hole 5. When the first connecting bolt 63 is continuously screwed into the inner cavity of the connecting groove 644, the fastening spring 641 is compressed. When the first connecting bolt 63 is screwed in to a certain extent, the fastening spring 641 is no longer compressed, thereby generating a force in the opposite direction, so that the first connecting bolt 63 is kept in a predetermined position. After the fixing assembly 6 is installed, the steel cable 7 is fixed into a whole. The steel cable 7 is used as a high-strength connecting member, and a plurality of berm bodies 1 are firmly connected together by binding to form a stable overall structure. Step 4: After several embankment bodies 1 are assembled through the fixing assembly 6, an arc-shaped baffle plate 91 is sleeved on the outer surface of two adjacent water-dividing tips 4 between every two embankment bodies 1. The arc-shaped baffle plate 91 is positioned through the second reserved hole 8 and the second mounting hole 92. After the position is determined, the second connecting bolt 93 is passed through the inner cavity of the second reserved hole 8 and the second mounting hole 92, and then the second fastening nuts 94 on both sides are rotated so that the arc-shaped baffle plate 91 is fixed on the outer surface of the water-dividing tip 4, and the assembly of the bridge embankment is completed. Since the structure at the water-dividing tip 4 is relatively thin, and a certain gap will be generated between two adjacent water-dividing tips 4, the gap will continue to expand under the impact of the water flow. The arc-shaped baffle plate 91 is used to prevent the connection between the water-dividing tips 4 from being impacted by the water flow, causing the structure to be damaged.
