[0002] In river management projects, retaining walls are often used to protect the safety of the bank slope. With the progress and development of society, people pay more and more attention to the harmonious coexistence of buildings and the ecological environment. At present, the retaining walls commonly used in rivers include gabion stone cage retaining walls, ordinary mortar masonry retaining walls, and reinforced concrete retaining walls.

Gabion stone cage retaining walls have gaps for fish and shrimp to inhabit and lay eggs, and have good ecology. However, since the exposed surface of the gabion stone cage retaining wall is a gabion net, it is difficult to maintain and manage in the later stage, and it is easy to be damaged or entangled with garbage, which makes the later maintenance and management work more troublesome.

[0026] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0027] Please also read Figures 1 to 3 The embodiment of the present application provides an ecological retaining wall 100, including a first barrier layer 10 and a second barrier layer 20, wherein the second barrier layer 20 is in contact with the bank slope, and the first barrier layer 10 is arranged on the side of the second barrier layer 20 facing the river channel. The first barrier layer 10 includes a plurality of building material layers stacked in sequence along the height direction of the river channel, and an activity space 10a with an opening facing the river channel is formed between two adjacent building material layers.

[0028] In this way, an activity space 10a with an opening toward the river channel is formed between two adjacent building material layers, so that the organisms in the river channel can inhabit and lay eggs, thereby providing a good living and breeding environment for the organisms, thereby improving the ecology of the ecological retaining wall 100, and is conducive to forming a natural appearance, so that the ecological retaining wall 100 is integrated with the surrounding environment, thereby improving the ornamental value of the ecological retaining wall 100. At the same time, the side of the ecological retaining wall 100 close to the river channel is a first retaining layer 10 formed by stacking multiple building material layers. The surface of each building material layer is more stable and reliable than the gabion mesh, which can effectively avoid the easy damage and garbage entanglement caused by the use of the gabion mesh, so that the later maintenance and management work is easier and more convenient, thereby reducing and simplifying the later maintenance and management work.

[0029] In some embodiments, two adjacent building material layers are partially connected by a first bonding material filled between the two, and the first bonding material is located on a side of the building material layer away from the river channel.

[0030] In this way, two adjacent building material layers are connected by semi-mortar masonry and semi-dry masonry, so that the two adjacent building material layers and the first bonding material together enclose a C-shaped activity space 10a. On the one hand, the first bonding material can make the connection between the two adjacent building material layers more stable and reliable, so as to improve the structural reliability of the first barrier layer 10, thereby ensuring the slope protection effect of the ecological retaining wall 100. On the other hand, it can also form an activity space 10a with an opening between the two adjacent building material layers for organisms in the river channel to inhabit and lay eggs, thereby providing a good living and breeding environment for the organisms, thereby improving the ecology of the ecological retaining wall 100.

[0031] Optionally, the first cementing material accounts for 0.2-0.8 of the dimension of the building material layer along the width direction of the river channel, for example, 0.3, 0.5, 0.6 or 0.7, etc. Thus, it can ensure that the first cementing material has a certain size to ensure the bonding stability of two adjacent building material layers, and ensure the size of the activity space 10a to facilitate the movement and habitat of organisms in the river channel.

[0032] Optionally, the first bonding material may be cement mortar, concrete or fusion mortar or other materials having strong bonding ability after curing. The specific setting may be based on actual needs and is not limited here.

[0033] In some embodiments, the building material layer includes a plurality of first masonry stones 11 sequentially arranged along the length direction of the river channel, a first joint is formed between two adjacent first masonry stones 11, and the first joints between two adjacent building material layers are staggered.

[0034] Thus, the first seams of the upper and lower building material layers are overlapped and vertical through seams are avoided, which is conducive to the formation of overall stress on the two adjacent building material layers, thereby improving the integrity and bearing capacity of the first barrier layer 10 and making the stress distribution of the first barrier layer 10 more uniform when subjected to thrust.

[0035] Optionally, the first masonry 11 has a relatively narrow side and a wide side along the width direction of the river channel, the thickness of the narrow side along the height direction of the river channel is smaller than the thickness of the wide side along the height direction of the river channel, and the wide side is arranged toward the second barrier layer 20 .

[0036] In this way, the narrow side of the first masonry 11 faces the river channel, that is, the narrow side is located on the opening side of the activity space 10a, so that the size of the activity space 10a can be increased while ensuring the reliability of the first barrier layer 10, so as to facilitate the movement and inhabitation of organisms in the activity space 10a, thereby improving the ecology of the ecological retaining wall 100.

[0037] Optionally, when the narrow edge is located on one side of the first stone 11 in the thickness direction or extends toward one side of the first stone 11 in the thickness direction, the narrow edge is set in a direction away from the bottom of the river channel, which can facilitate the formation of activity space 10a and facilitate the entry of organisms into the activity space 10a.

[0038] Optionally, the wide side is embedded in the second barrier layer 20. Thus, the embedding depth of the first masonry 11 and the second barrier layer 20 can be increased, the individual stability of the first masonry 11 can be enhanced, the bearing capacity of the first barrier layer 10 can be improved, and the connection between the first barrier layer 10 and the second barrier layer 20 can be made more stable and reliable, so as to improve the connection reliability between the first barrier layer 10 and the second barrier layer 20, thereby improving the slope protection effect of the ecological retaining wall 100.

[0039] In some embodiments, each building material layer has only one first masonry stone 11 along the width direction of the river channel, so that the second retaining layer 20 accounts for a larger proportion of the ecological retaining wall 100, which is beneficial to improve the structural reliability of the ecological retaining wall 100, while simplifying the construction steps of the first retaining layer 10 and reducing the construction difficulty of the first retaining layer 10.

[0040] It can be understood that in other embodiments, each building material layer may also include a plurality of first masonry stones 11 arranged in sequence along the width direction of the river channel. As can be seen from the above, the first joints of two adjacent building material layers along the length direction of the river channel are staggered. Based on this, the first joints of the plurality of first masonry stones 11 along the width direction of the river channel are staggered in the height direction, that is, the first joints of the two adjacent building material layers along the width direction of the river channel are staggered, and the first joints of the same building material layer along the length direction of the river channel are staggered. This can avoid vertical through joints and horizontal through joints, which is conducive to the formation of an overall force on the plurality of first masonry stones 11, thereby improving the integrity and bearing capacity of the first barrier layer 10.

[0041] In some embodiments, the second barrier layer 20 includes a plurality of second masonry stones 21 and a second bonding material filled between the plurality of second masonry stones 21 , and the second masonry stones 21 and the second bonding material are laid together to form a masonry body.

[0042] In this way, the second barrier layer 20 is formed into a masonry body by the second masonry stone 21 and the second binder material, which can make the second barrier layer 20 have greater strength and good integrity, so as to improve the bearing capacity of the ecological retaining wall 100, thereby improving the ecology of the ecological retaining wall 100.

[0043] Optionally, a plurality of the second masonry stones 21 are arranged in sequence on the same horizontal plane and are laid with the second adhesive material to form a masonry layer, two adjacent masonry stones in the same masonry layer form a second joint, and two adjacent second joints in the same masonry layer are staggered. This can help ensure that the masonry layer is staggered horizontally, so as to improve the integrity of the masonry layer, and further improve the bearing capacity of the second barrier layer 20.

[0044] Optionally, the second barrier layer 20 includes a plurality of masonry layers stacked in the height direction of the river channel, and the second joints of two adjacent masonry layers are staggered, so as to ensure that the two adjacent masonry layers are vertically staggered, so as to further improve the integrity of the masonry layers and the bearing capacity of the second barrier layer 20.

[0045] Optionally, the length of the first joint and the second joint extending in the width direction or the length direction of the river channel is 15 mm-20 mm, for example, 16 mm, 18 mm, or 19 mm. The length of the first joint and the second joint extending in the height direction of the river channel is 20 mm-30 mm, for example, 22 mm, 25 mm, or 18 mm. Thus, the size of the masonry joint can be ensured, so as to ensure the area of ​​the first bonding material and the second bonding material, improve the connection reliability of the two adjacent first masonry stones 11 and the two adjacent second masonry stones 21, and further ensure the bearing capacity of the ecological retaining wall 100.

[0046] Optionally, the second bonding material may be cement mortar, concrete or fusion mortar or other materials having strong bonding ability after curing. The specific setting may be based on actual needs and is not limited here.

[0047] In some embodiments, the ecological retaining wall 100 further includes a third barrier layer 30 disposed on the top of the first barrier layer 10 and the second barrier layer 20, the third barrier layer 30 includes a plurality of third masonry stones and a third bonding material filled between the plurality of third masonry stones, and the top of the third barrier layer 30 is kept flat or substantially flat. Thus, the third barrier layer 30 forms a flat surface for pedestrians to walk on, effectively avoiding the situation of hanging feet caused by the use of gabion mesh, thereby improving safety and reducing the work of later maintenance and management.

[0048] Optionally, the first masonry stone 11, the second masonry stone 21 and the third masonry stone can be pebbles, so that materials can be screened and obtained from the river channel, so as to simplify the construction steps and reduce the construction cost.

[0049] It can be understood that in other embodiments, the first masonry stone 11, the second masonry stone 21 and the third masonry stone can also be granite or other stone materials.

[0050] Optionally, the sizes of the first masonry stone 11, the second masonry stone 21 and the third masonry stone may be larger than 150 mm, for example, 160 mm, 200 mm, 250 mm or 300 mm, etc., which can be set according to actual needs and actual conditions and are not limited here.

[0051] In some embodiments, the ecological retaining wall 100 further includes a base layer 40 , which is disposed at the bottom of the first barrier layer 10 and the second barrier layer 20 and is bonded to the first barrier layer 10 and the second barrier layer 20 .

[0052] Thereby, a stable and reliable foundation can be provided for the first retaining layer 10 and the second retaining layer 20 to ensure the stability of the ecological retaining wall 100 relative to the river channel, thereby improving the bearing capacity of the ecological retaining wall 100 .

[0053] Optionally, the material of the base layer 40 may be embedded stone concrete or plain concrete, so that the base layer 40 forms a stable structure to provide a stable and reliable masonry foundation for the first barrier layer 10 and the second barrier layer 20 .

[0054] For ease of reading and understanding, the following is a brief description of the construction steps of the ecological retaining wall 100:

[0055] Before paving, firstly, the soil of the bank slope and the riverbed is excavated along the excavation line, and the stones (the first masonry stone 11, the second masonry stone 21 and the third masonry stone) are sprinkled with water to moisten them so that their surfaces can fully absorb the water and avoid residual water accumulation.

[0056] After excavation is completed, a foundation layer 40 is constructed below the riverbed surface by buried stone concrete or plain concrete.

[0057] After the base layer 40 is solidified, the first barrier layer 10 and the second barrier layer 20 are laid layer by layer. When laying the first barrier layer 10, the first adhesive material is used to sequentially bond the two adjacent first masonry stones 11 through a semi-mortar and semi-dry process, and the first joints are laid in a staggered manner. When laying the second barrier layer 20, the second masonry stones 21 are first placed, and then the second adhesive material is poured from the top to the inside, and the tool (such as a flat iron) is used to gently tamp until the surface is covered with mortar, and the second joints are laid in a staggered manner.

[0058] After one layer is laid, the next layer can be laid. But before continuing to lay, the strength of the completed masonry must be ensured and the scum on the surface of the masonry must be cleaned.

[0059] When the construction of the topmost first barrier layer 10 and the second barrier layer 20 is completed, two adjacent third masonry stones are paved with a third bonding material to form a flat third barrier layer 30 .

[0060] After the entire ecological retaining wall 100 is built, the exposed surface of the ecological retaining wall 100 is watered and maintained on time.

[0061] Finally, the excavated part is backfilled with backfill materials 200 such as sand and gravel to make it flush with the surface of the riverbed and the slope of the bank.

[0062] In this way, the construction of the ecological retaining wall 100 is completed.

[0063] The ecological retaining wall 100 provided by the present application is adopted, and the foundation layer 40 is used to provide a foundation for the first retaining layer 10 and the second retaining layer 20 to improve the stability of the ecological retaining wall 100. The first retaining layer 10 and the second retaining layer 20 form a stable masonry structure to resist the impact force and the gravity of the bank slope and protect the stability of the bank slope. By setting a flat third retaining layer 30 on the top of the first retaining layer 10 and the second retaining layer 20, it is convenient for pedestrians to walk. In addition, the first retaining layer 10 forms an activity space 10a with an opening facing the river channel through semi-mortar masonry and semi-dry masonry, so as to provide a good living and breeding environment for the organisms in the river channel to improve the ecology of the ecological retaining wall 100, and is conducive to forming a natural appearance, so that the ecological retaining wall 100 is integrated with the surrounding environment to improve the ornamental value of the ecological retaining wall 100. At the same time, the side of the ecological retaining wall 100 close to the river channel is a first retaining layer 10 composed of multiple building material layers stacked together. The surface of each building material layer is more stable and reliable than the gabion mesh, and can effectively avoid the easy damage and garbage entanglement caused by the use of the gabion mesh, so that the subsequent maintenance and management work is easier and more convenient, thereby reducing and simplifying the subsequent maintenance and management work.

[0064] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
