Description

Technical Field

[0001] This utility model relates to the field of riverbank slope technology, specifically to a flood control device for riverbank slopes. Background Technology

[0002] Riverbank slopes refer to the sloping surfaces on both sides of a river. The construction of slopes can provide support and protection for roads and facilitate access to the river. Most existing riverbank slopes are earthen slopes or earthen slopes with one side revetment. When floods occur, riverbank slopes are often eroded by rainwater, resulting in land loss and damage to the revetment, and are unable to effectively resist floods.

[0003] Patent document CN222139911U discloses a river channel with flood-resistant slope protection. The slope protection effectively resists the impact of river water and prevents slope erosion. Laying paving stones on the slope protection increases its stability and reduces the possibility of soil erosion and water loss. The paving stones also provide some protection, shielding the slope from external environmental erosion. Vegetation reduces soil erosion, maintains water source stability, and protects the slope and water resources. When water impacts the buffer plate, the curved upper end of the plate causes the water to return after impact, reducing splashing. However, the buffer device is easily corroded by prolonged immersion in river water, and the accumulation of silt between the buffer plate and the fixing plate can cause it to lose its buffering effect. Therefore, this technical solution has high maintenance costs and is not suitable for use in rivers with high silt content.

[0004] Patent document CN212561383U discloses a secondary flood control dike for riverbank slopes. In use, the flood control panel is swung to a horizontal position and the mounting base is fixed to the riverbank slope. During this process, because the flood control panel is horizontal, this device is equivalent to the base of a secondary dike in existing technologies, meaning it occupies less space. It is also more convenient for a single person to transport, lay, and fix the dike when working on narrow riverbank slopes. After fixing the mounting base to the riverbank slope, a drive assembly drives the flood control panel to a tilted position, and a locking element abuts against the drive assembly to prevent the panel from swinging back to a horizontal position, thus fixing the flood control panel in the tilted state and enabling it to prevent river water from washing away. However, this technical solution involves many connecting components, resulting in high production costs and complicated maintenance, making it unsuitable for long-term use. Utility Model Content

[0005] The main purpose of this utility model is to provide a flood control device for riverbank slopes that is suitable for long-term laying and use, can effectively green the slopes, and has low production costs.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A flood control device for riverbank slopes includes a vertical section and an inclined section at the upper end of the vertical section. The upper end of the inclined section is inclined outward from the river channel. The vertical section and the inclined section are integrally formed to form a slope protection. The slope protection is hollow inside and the upper end of the inclined section is open. Multiple through holes are provided on the side of the inclined section facing the river channel. The multiple through holes are arranged in a rectangular array. A support plate is fixed on the inclined section below each row of through holes. The two ends of the slope protection are respectively provided with grooves and protrusions. The grooves and protrusions correspond to each other. When two adjacent slope protections are combined, the protrusion of one slope protection can be inserted into the groove of the other slope protection.

[0008] Specifically, the upper end of the inclined portion is parallel to the lower end of the vertical portion.

[0009] Specifically, vertical holes are provided at both ends of the inclined portion, the axis of the vertical holes is parallel to the horizontal plane, and the vertical holes penetrate the inclined portion.

[0010] Specifically, the slope protection is formed by pouring concrete.

[0011] Specifically, multiple reinforcing ribs are provided on both the side of the slope facing the river and the side away from the river, with the upper end of the reinforcing ribs protruding above the inclined portion.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The vertical and inclined sections are integrally formed (concrete casting), avoiding the weak joints of traditional segmented structures and enhancing the overall scour resistance. The grooves and convex edges of adjacent slope protections quickly fit together to form a continuous and tight protective surface, reducing the risk of water seepage and localized damage, making it especially suitable for rivers with high sediment content.

[0014] 2. After filling the slope with soil, green plants are planted through the openings. The root system can stabilize the soil and prevent erosion, while forming an ecological slope and reducing the ecological damage caused by pure concrete structures. The support plate intercepts rainwater and guides it to the roots of the plants in the openings, realizing automatic irrigation, reducing the frequency of manual maintenance, and extending the survival period of the plants.

[0015] 3. The slope protection structure allows for rapid assembly via a plug-in connection, eliminating the need for complex connecting components (such as bolts or hinges), thus reducing construction time and labor costs. The concrete pouring combined with internal reinforcing ribs ensures strength while preventing long-term corrosion of metal components, reducing subsequent maintenance costs.

[0016] 4. Anchor rods or steel bars can be inserted into the vertical holes at both ends of the inclined section to further fix the slope. The reinforcing bars extend to the top of the slope and are pre-embedded in the top road of the embankment to improve the integrity of the slope and the road and make it less likely to shift when resisting flood impact.

[0017] 5. The slope of the revetment is designed to face the river channel, and the through holes disperse the water flow pressure, reducing direct impact; the concrete material has strong corrosion resistance and is suitable for long-term underwater environments. The hollow structure, after being filled with soil, increases its self-weight, and combined with the design of the revetment and the river embankment, it prevents floods from eroding the slope.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figures 1-5 As shown, a flood control device for a riverbank slope includes a vertical part 1 and an inclined part 2 at the upper end of the vertical part 1. The upper end of the inclined part 2 is inclined outward from the river channel, and the upper end of the inclined part 2 is parallel to the lower end of the vertical part 1. The vertical part 1 and the inclined part 2 are integrally formed to constitute a slope protection. The slope protection is formed by pouring concrete.

[0027] Vertical holes 5 are provided at both ends of the inclined part 2. The axis of the vertical holes 5 is parallel to the horizontal plane and the vertical holes 5 penetrate the inclined part 2.

[0028] The slope is hollow inside and the upper end of the inclined part 2 is open. Multiple through holes 6 are opened on the side of the inclined part 2 facing the river channel. The multiple through holes 6 are arranged in a rectangular array. A support plate 7 is fixed on the inclined part 2 below each row of through holes 6. The two ends of the slope are respectively provided with grooves 4 and protrusions 3. The grooves 4 and protrusions 3 correspond to each other. When two adjacent slopes are combined, the protrusions 3 of one slope can be inserted into the grooves 4 of the other slope.

[0029] Before laying the slope protection, the side of the riverbank 9 facing the river channel is trimmed so that the lower part of the side of the riverbank 9 facing the river channel is a vertical surface and the upper part is an inclined surface. After the slope protection is laid, the side of the slope protection away from the river channel can fit into the side of the riverbank 9 facing the river channel.

[0030] The slope protection is laid on the side of the riverbank 9 facing the river channel. When two adjacent slope protections are combined, the protruding edge 3 of one slope protection can be inserted into the groove 4 of the other slope protection.

[0031] After the slope protection is laid, the drill rod can be passed through the vertical hole 5, so that the part of the drill rod below the vertical hole 5 is inserted into the river embankment 9, thereby improving the stability of the slope protection.

[0032] After the slope protection is laid, soil is filled into the slope protection. Filling the slope protection with soil increases its weight, thus allowing the slope protection to adhere tightly to the river embankment 9. When filling the slope protection with soil, in order to prevent soil from leaking out of the through holes 6, baffles can be placed in the through holes 6. After the slope protection is filled with soil, the soil corresponding to the through holes 6 is compacted using the baffles, thereby preventing soil from leaking out of the through holes 6.

[0033] After filling the slope with soil, green plants can be planted in the soil through the through holes 6. After the green plants grow, they can green the slope.

[0034] By setting up the support plate 7, the support plate 7 can intercept rainwater on the slope when it rains, and can irrigate the green plants in the through hole 6.

[0035] Example 2: Based on Example 1, referring to... Figure 6 As shown, multiple reinforcing ribs 8 are provided on both the side of the slope facing the river and the side away from the river, with the upper end of the reinforcing ribs 8 protruding above the inclined part 2.

[0036] The strength of the slope protection can be increased by setting the reinforcing ribs 8. After the slope protection is laid, the top road 10 is laid on the upper end of the river embankment 9. The top road 10 can cover the upper end of the slope protection. The reinforcing ribs 8 protruding to the upper end of the slope protection can be pre-embedded in the top road 10. After the top road 10 is laid, the stability of the slope protection can be improved.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
