Description

Technical Field

[0001] The utility model relates to the technical field of bank protection structures, in particular to a river ecological bank protection structure. Background Art

[0002] The river ecological bank protection structure is a comprehensive slope protection system that combines multidisciplinary knowledge such as engineering mechanics, soil science, ecology and botany. It aims to protect the stability of the river bank while promoting the restoration and protection of the ecological environment.

[0003] In my country, soil erosion has reached a serious level. It not only affects production development, but also leads to serious deterioration of the ecological environment, frequent natural disasters, and ultimately leads to ecological imbalance.

[0004] The bank slope protected by hexagonal hollow brick ecological bank protection technology has an immature structural design. Under rainfall conditions, runoff is formed on the slope surface, causing soil loss in the hollow bricks. When the scouring time becomes longer, local collapse is very likely to occur, eventually leading to landslides. Therefore, a river ecological bank protection structure is proposed.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a river ecological bank protection structure with the following features:

[0014] Beneficial effects:

[0015] The utility model adopts a special structural design in which the blocks are set to have unequal heights at both ends. During the rainfall process, rainwater can dissipate energy step by step along the slope, and the potential energy of the falling rainwater cannot be added. The stability of the entire embankment is achieved by stabilizing the local small plane, effectively preventing the damage to the surface and shallow layers of the slope caused by rainfall, so as to keep the moisture and soil of the embankment to the greatest extent. The anti-slip teeth of the bank protection blocks fully engage with the bank slope foundation, directly transmitting the gravity of the blocks to the slope surface, significantly reducing the external force transmitted by the blocks to the gravity of the lower layer, and avoiding the sliding force generated by the self-weight of the brick body, which causes the brick body to be squeezed and damaged, causing the overall collapse of the bank slope. The bank protection blocks are hollow hexagonal inside and regular hexagonal outside. The bottom surface forms an angle α with the horizontal plane, and the size of the angle α is consistent with the slope of the bank protection. When laying the bank protection bricks, the upper end can maintain a horizontal state, and the soil in the bank protection block is in a stable state, which ensures that the soil does not lose to the greatest extent. In summary, the problems raised in the background technology are solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a technical solution, a river ecological bank protection structure, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , including revetment blocks, which are composed of hollow hexagonal blocks 1 with unequal heights at the front and rear ends to form a combination of multiple blocks with horizontal upper parts, the lower end of the hollow hexagonal block 1 is provided with anti-slip teeth 4, and the anti-slip teeth 4 are integrally formed with the hollow hexagonal block 1, and an inner cavity 2 is provided inside the hollow hexagonal block 1, and the inner cavity 2 is hexagonal and hollow.

[0025] See also Figure 4 and Figure 5 The inner cavity 2 is provided with fill soil, and the thickness of the fill soil is 200 mm.

[0026] See also Figure 4 and Figure 5 Aquatic plants 5 are arranged on the upper end of the fill, and the aquatic plants 5 are planted on the upper end of the fill.

[0027] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 An inner groove 3 is provided inside the inner cavity 2, and the inner groove 3 is integrally formed with the inner cavity 2, and the inner groove 3 is filled with soil to improve the stability of the filling.

[0028] This solution: By utilizing the special structural design of the front and rear ends of the revetment blocks being of unequal height, the surface of the protected slope is changed from the inclined surface formed by the hollow hexagonal block 1 to a combination of multiple blocks with horizontal upper parts. During rainfall, rainwater can dissipate energy step by step along the slope, and the potential energy of falling rainwater cannot be added. The stability of the entire embankment is achieved by the stability of the local small planes, effectively preventing damage to the surface and shallow layers of the slope caused by rainfall, so as to maximize the retention of moisture and soil on the embankment. In addition, for the slope paved with hollow hexagonal blocks 1, the pressure accumulated in the downward direction of the slope gradually increases, which can easily cause damage to the brick body and cause the entire slope to lose stability. Through experimental research, in order to reduce the sliding force generated by the self-weight component of the new revetment blocks, a set of anti-slip teeth 4 with a tooth length of 2 cm are designed at the bottom of the new revetment blocks. The anti-slip teeth 4 of the revetment blocks fully engage with the bank slope foundation, directly transmitting the gravity of the blocks to the slope surface, significantly reducing the external force transmitted by the blocks to the gravity of the lower layer, avoiding the sliding force generated by the self-weight of the bricks, which causes the bricks to be squeezed and damaged, and causing the overall collapse of the bank slope. The revetment blocks are hollow inside hexagons and regular outside. The bottom surface forms an angle α with the horizontal plane, and the size of the angle α is consistent with the slope of the revetment. When laying revetment bricks, the upper end can remain horizontal, and the soil in the revetment blocks is in a stable state, which can ensure that the soil does not lose to the greatest extent. Ecological blocks are used at the foot of the embankment on one or both sides of the project. Solid hexagonal blocks are used to protect the slope to the normal water level. Above the normal water level to the top of the embankment, 1:2.5 hollow hexagonal blocks are used to plant grass for slope protection. The bottom uses C20 concrete feet, the foundation top elevation is -0.7m, and the ecological blocks are built to the average water level elevation of 0.50m. A 2m wide platform along the river is set on the top of the embankment. The hollow hexagonal block 1 is filled with 200mm thick soil and aquatic plants 5 are planted. Geogrid reinforcement bars are laid at a height of 480mm on the back of the wall. C20 concrete is used as the top of the embankment. Φ120 pine piles are used as the foundation. This type of revetment is about 10km long.
