[0002] With the development of social economy, people gradually realize that green, low-carbon and sustainable development is an inevitable requirement for ecological environment construction. With the development of large-scale ships, the long-term action of navigation waves generated by large ships during navigation will cause fatigue damage to the dock structure and even cause structural damage. The impact of waves may also cause scouring and erosion of the dock revetment structure. The dock revetment structure is a building attached to the main body of the shore. Its main function is to prevent the erosion of its land by wave impact. However, the traditional revetment reinforcement method has a large disturbance on the bank slope, and cement, chemical and other grouting materials seriously pollute the water and soil, seriously endangering the surrounding environment.

[0003] The ecological bank protection structure can not only resist wave scouring and maintain the stability of the bank slope, but also protect the ecosystem of the basin. However, the ecological bank protection structure cannot sustainably protect the stability of the bank slope under the action of long-term wave scouring, and cracks and other damage will still occur in the bank protection. How to protect the function of the water body ecosystem while taking into account the long-term stability of the bank protection structure is a difficult problem faced by bank protection engineering design. Summary of the invention

[0008] The ceramsite capsule is composed of urease-producing bacteria and porous ceramsite. The urease-producing bacteria is one or more of Bacillus pasteurianus, Sporosarcina pasteurianus, Bacillus cereus, Bacillus thuringiensis and Bacillus cohnii.

[0009] The cross section of the energy dissipation block is a regular hexagon, and adjacent energy dissipation blocks face each other vertically.

[0010] A flat net is arranged in the cavity of the energy dissipation template at a location where the energy dissipation block is fitted.

[0011] A self-repairing ecological energy dissipation bank protection method for sand-mudstone interlayer slope comprises the following steps: Step 1) Install a vertical template on the shore, and reserve holes on the vertical template at a certain interval; Step 2) Fill the installed upright formwork with the corresponding revetment materials according to the specification requirements, and prefabricate the concrete embedded rods in the reserved holes, wherein the rear 1 / 2 of the concrete embedded rods is set inside the revetment body, and the front 1 / 2 is close to the water body; Step 3), customize the energy dissipation template, network management system, flat net; prepare the corresponding number of ceramsite capsules, mix the ceramsite capsules, coconut brick plant shells, and hydrophilic vegetation seeds in a mass ratio of 1:2:1, and place them in a dry storage box for later use; Step 4), the network management system is placed in the middle of the energy dissipation template, and the energy dissipation template is divided into two cavities on the left and right. The left and right cavities of the network management system are filled with a mixture of ceramsite capsules, coconut brick plant shells, and hydrophilic vegetation seeds. The flat net is set in the energy dissipation block to separate the vegetation growth material from the energy dissipation block. The network management system is connected to the grouting slot pipe, and the water stop valve is closed to prevent soil, gravel and other materials from clogging the grouting slot pipe; Step 5), connect the positioning buckle of the energy dissipation formwork with the pre-embedded concrete rod to realize the integration of the energy dissipation formwork and the revetment body; Step 6), in the early stage of hydrophilic vegetation seed growth, when the wave impacts the energy dissipation module, the water flows into the energy dissipation cavity from the energy dissipation hole on the energy dissipation block, and the channel in the energy dissipation cavity is curved to disperse the impact force of the water flow, thereby achieving a good energy dissipation effect; Step 7), in the later growth stage of the hydrophilic vegetation seeds, open the water stop valve, and the nutrients and calcium source substances enter the cavity of the energy dissipation module through the grouting channel pipe to ensure the long-term supply of hydrophilic vegetation growth substances in the later stage; the hydrophilic vegetation seeds germinate and grow into hydrophilic vegetation, and the roots of the hydrophilic vegetation take root and distribute between the ceramsite capsules and the coconut brick plant shells, and the stems and leaves of the hydrophilic vegetation grow through the flat net and the energy dissipation holes; part of the water flows through the flat net into the cavity of the energy dissipation template, and the water restores the mineralization activity of the microorganisms inside the cavity, inducing the production of a large amount of calcium carbonate precipitation to wrap the ceramsite capsules, coconut brick plant shells, and the roots of the hydrophilic vegetation, thereby improving the overall stability.

The energy dissipation template 17 is provided with a positioning buckle 3 on one side close to the concrete embedded part revetment.

[0033] like Figure 6-8 As shown, a spring 19 and an active clamp 20 are arranged on the inner wall of the positioning buckle 3. A concave card slot 18 is arranged on the concrete embedded rod 2. The concrete embedded rod 2 is connected with the positioning buckle 3 using the key lock principle.

When the concrete embedded rod 2 enters the inner area of ​​the positioning buckle 3, the active clamps 20 correspond to the fixed concave card slots 18 one by one under the action of the spring 19.

[0034] like Figure 9-12 As shown, the energy dissipation template 17 is provided with an energy dissipation block 4 near the water body side, and tenons 21-1 are provided at the four inner corners of the energy dissipation block 4, which are clamped with the tenon clamping area 21-2 of the energy dissipation template 17, and the internal cross-section of the energy dissipation block 4 is a regular hexagon, and the upper top surface of the regular hexagon is connected to the lower top surface, and a plurality of circular energy dissipation holes 5 are provided on the energy dissipation block 4; the bottom areas between the circular energy dissipation holes 5 are connected to form an energy dissipation cavity 6; the energy dissipation cavity 6 and the energy dissipation holes 5 form a water inlet channel and a water outlet channel.

[0035] The energy dissipation block 4 is provided with a network management system in the energy dissipation template 17, and the network management system includes a pipe network 9, a grouting slot pipe 7, and a water stop valve 8. Through holes 11 are distributed on the surface of the pipe network; slurry outlets 10 are arranged on the left and right sides of the pipe network 9, and the slurry outlets 10 penetrate into the left and right cavities of the energy dissipation template 17 to ensure that nutrients and calcium sources can be evenly injected in the later stage; a grouting slot pipe 7 is arranged on the top surface of the pipe network; and a water stop valve 8 is arranged in the middle of the grouting slot pipe 7.

[0049] 4) The network management system, the flat net 16, and the mixture of the ceramsite capsule 12, the coconut brick plant shell 13, and the hydrophilic vegetation seeds 14 are assembled and installed in sequence into the energy dissipation template 17, the grouting channel pipe 7 is connected, and the water stop valve 8 is closed.

[0050] 5) Connect the positioning concave buckle 3 of the energy dissipation template 17 to the pre-embedded concrete rod 2 to form a whole with the pre-embedded concrete revetment.
