The concrete slope protection in the embodiment comprises an underwater horizontal section M1, an underwater inclined section M2, an overwater inclined section I M3 and an overwater inclined section II M4 (see figure 1) which are connected in sequence. Wherein the content of the first and second substances,

the ecological sac units N1 (shown in figure 2) installed in the underwater horizontal segment M1 and the underwater inclined segment M2 are uniformly distributed at intervals according to a rectangular lattice shape, and can also be distributed among the stressed reinforcing meshes of the concrete slope protection by adopting other distribution modes according to actual conditions, and are all positioned in a concrete layer below a water level line, and the concrete structure of the ecological sac units is as follows:

every ecological bag unit all includes the ecological bag 1 that is used for the splendid attire soil of planting, and it comprises stereoplasm bag neck 101 and utricule 102, and the open-top of stereoplasm bag neck 101 and concrete bank protection surface parallel and level are sealed through closing cap 2, and the bottom is passed through flaring structure and is linked to each other with utricule 102. The capsule 102 may be a hard capsule made of engineering plastics, and has certain strength and certain shape, so that the capsule can be used as a concrete pouring template; the above-mentioned capsule 102 can also adopt a flexible capsule with a lower price, which is usually made of materials such as polyethylene and polypropylene through blow molding and injection molding, and in order to overcome the disadvantage that the materials are soft and easy to deform, the ecological capsule 1 needs to be pressurized before the installation of the cover 2, so that the ecological capsule can keep a certain shape and can be used as a concrete pouring template.

The diameter of the sealing cover 2 is larger than that of the hard bag neck 101, a pull ring cover convenient to open is adopted, and planting soil is filled into the ecological bag 1 after concrete pouring is finished. In order to provide a good growth environment for green plants, drip irrigation joint pipes 103 are arranged on the hard bag neck 101 of each ecological bag 1, and each drip irrigation joint pipe 103 is in threaded connection with a drip irrigation header pipe. During drought, water and nutrients can be supplemented through the drip irrigation header pipe. In this case, the bottom of capsule 102 does not need to be provided with a drainage structure.

The hard bag neck 101 is integrally provided with two water stop rings 3 with a distance not less than 5cm for preventing the occurrence of permeation damage. In order to fix the water stop ring 3, a plurality of support columns 4 are arranged around the water stop ring, the top of each support column 4 is fixedly connected with the sealing cover 2, and the bottom of each support column 4 is connected with the flaring structure of the ecological sac 1.

every ecological bag unit all includes the ecological bag 1 that is used for the splendid attire soil of planting, and it comprises stereoplasm bag neck 101 and utricule 102, and the open-top of stereoplasm bag neck 101 and concrete bank protection surface parallel and level are sealed through closing cap 2, and the bottom is passed through flaring structure and is linked to each other with utricule 102. The capsule 102 may be a hard capsule made of engineering plastics, and has certain strength and certain shape, so that the capsule can be used as a concrete pouring template; the above-mentioned capsule 102 can also adopt a flexible capsule with a lower price, which is usually made of materials such as polyethylene and polypropylene through blow molding and injection molding, and in order to overcome the disadvantage that the materials are soft and easy to deform, the ecological capsule 1 needs to be pressurized before the installation of the cover 2, so that the ecological capsule can keep a certain shape and can be used as a concrete pouring template.

The diameter of the sealing cover 2 is larger than that of the hard bag neck 101, a pull ring cover convenient to open is adopted, and planting soil is filled into the ecological bag 1 after concrete pouring is finished. In order to provide a good growth environment for green plants, drip irrigation joint pipes 103 are arranged on the hard bag neck 101 of each ecological bag 1, and each drip irrigation joint pipe 103 is in threaded connection with a drip irrigation header pipe. During drought, water and nutrients can be supplemented through the drip irrigation header pipe. In order to prevent the humidity of the planting soil from being too high, a drain joint pipe 104 is installed at the bottom of the capsule 102 and is connected with a drain main pipe in a threaded manner. The main drainage pipe is laid near the lower layer of reinforcing mesh during the second construction.

The hard bag neck 101 is integrally provided with two water stop rings 3 with a distance not less than 5cm for preventing the occurrence of permeation damage. In order to fix the water stop ring 3, a plurality of support columns 4 are arranged around the water stop ring, the top of each support column 4 is fixedly connected with the sealing cover 2, and the bottom of each support column 4 is connected with the flaring structure of the ecological sac 1. The support columns 4 are bound and connected with the concrete slope protection surface layer reinforcing mesh and are used for fixing the ecological sac 1 in position; secondly, a fixing ring 5 used for binding and connecting with a concrete slope protection lower layer reinforcing mesh is arranged at the bottom of the capsule body 102; through the solid fixed ring 5 and the connection of stereoplasm bag neck 101 department support column and concrete bank protection reinforcing bar net, can prevent to pour the in-process at the concrete vibration, ecological bag 1 is extruded or takes place the displacement because of the dead weight is lighter under the exogenic action.

(III) ecological bag unit N3 (see figure 4) of installation in II sections M4 of slope on water is according to the even interval distribution of rectangle lattice form, also can adopt other ways of laying to lay between concrete bank protection atress reinforcing bar net according to actual conditions, and above-mentioned ecological bag unit is located the waterline, and every ecological bag unit upper portion is located the concrete layer of bank protection, and the lower part is located the soil property bank slope of bank protection, and its concrete structure is as follows:

every ecological bag unit all includes the ecological bag 1 that is used for the splendid attire soil of planting, and it comprises stereoplasm bag neck 101 and utricule 102, and the open-top of stereoplasm bag neck 101 and concrete bank protection surface parallel and level are sealed through closing cap 2, and the bottom is passed through flaring structure and is linked to each other with utricule 102. The capsule 102 may be a hard capsule made of engineering plastics, and has certain strength and certain shape, so that the capsule can be used as a concrete pouring template; the above-mentioned capsule 102 can also adopt a flexible capsule with a lower price, which is usually made of materials such as polyethylene and polypropylene through blow molding and injection molding, and in order to overcome the disadvantage that the materials are soft and easy to deform, the ecological capsule 1 needs to be pressurized before the installation of the cover 2, so that the ecological capsule can keep a certain shape and can be used as a concrete pouring template.
