[0001] The utility model relates to the technical field of river landscape engineering, in particular to a river embankment slope protection structure. Background Art

[0002] With the development of the urbanization process, landscape rivers have become more and more common. The Chinese utility model patent CN204139121U discloses a river slope protection concrete curing structure, which includes a bottom plate. A first-poured slope protection is longitudinally arranged upward at the front section of the bottom plate. A second-poured slope protection steel bar bracket is arranged at the rear section of the top of the first-poured slope protection. A longitudinally arranged curing water pipe is erected on the second-poured slope protection steel bar bracket. A plurality of water spraying holes are circumferentially arranged on the pipe wall of the curing water pipe. A water pump is placed on the first-poured slope protection. A first hose is arranged between the curing water pipe and the water pump. A second hose is connected between the water pump and the river in front of the bottom plate.

[0003] At present, most of the existing river embankment slope protections adopt the above forms such as reinforced concrete dams, etc. The construction investment is large, the construction period is long, and it is easy to collapse after long-term use. Therefore, it is necessary to provide a river embankment slope protection structure that can solve the problems of large construction investment, long construction period, and short service life of the river embankment slope protection in the form of reinforced concrete dams in the prior art. Summary of the Invention

[0004] The purpose of the utility model is to provide a river embankment slope protection structure that can solve the problems of large construction investment, long construction period, and short service life of the river embankment slope protection in the form of reinforced concrete dams in the prior art.

[0005] The utility model is realized as follows:

[0006] A river embankment slope protection structure includes a base layer, a permeable protection cage, river embankment soil, and slope protection turf. The base layer is constructed at the junction position between the river and the river embankment. The permeable protection cage is placed on the base layer, and the top of the permeable protection cage is higher than the water surface height of the river. River embankment soil is backfilled to form a river embankment between the permeable protection cage and the river bank. The top surface of the river embankment soil is higher than the top surface of the permeable protection cage, and the river embankment soil forms a slope protection structure with a slope structure from the top surface to the top of the permeable protection cage. The slope protection turf is laid and planted on the slope protection structure of the river embankment soil.

[0007] The permeable protection cage includes a protection cage main body and pebbles installed in the protection cage main body. The particle size of the pebbles is larger than the mesh aperture of the protection cage main body.

[0008] The base layer is a concrete base layer, and the base layer is constructed longitudinally along the width direction of the river.

[0009] A plurality of the permeable protection cages are sequentially stacked on the base layer along the length direction of the base layer, so that a plurality of permeable protection cages are longitudinally arranged along the width direction of the river.

[0010] The width of the permeable protection cage is the same as that of the base layer, with one side of the permeable protection cage facing the river channel and the other side being attached to the river embankment soil.

[0011] The top elevation of the permeable protection cage is higher than the bottom elevation of the slope protection structure.

[0012] The river embankment soil includes base soil and planting soil. The planting soil is backfilled on the top of the base soil, and the slope protection turf is laid and planted on the planting soil of the slope protection structure.

[0013] The height of the planting soil is not less than 1 m.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. Since the utility model is provided with a base layer and a permeable protection cage, the main body of the protection cage is filled with pebbles. The permeable protection cage is arranged on the base layer between the river channel and the river embankment soil. The permeable protection cage can allow river water to pass through, and the top elevation of the main body of the protection cage is higher than the bottom elevation of the slope protection structure, which can provide safe and reliable protection for the river embankment soil and prevent the river embankment soil from collapsing.

[0016] 2. Since the utility model is provided with river embankment soil and slope protection turf, the river embankment soil is backfilled between the permeable protection cage and the river bank. The construction method is simple, without the need to pour a reinforced concrete dam, which greatly shortens the construction period and reduces the construction cost. At the same time, the planting of the slope protection turf makes the river embankment less likely to collapse, further improving the safety and aesthetics of the river embankment.

[0021] The following further describes the utility model in conjunction with the drawings and specific embodiments.

[0022] Please refer to the appendix Figure 1, A river embankment slope protection structure, including a base layer 1, a permeable protection cage 2, river embankment soil 3, and slope protection turf 4; the base layer 1 is constructed at the junction of the river channel 5 and the river embankment 6, the permeable protection cage 2 is placed on the base layer 1, and the top of the permeable protection cage 2 is higher than the water surface height of the river channel 5; the river embankment soil 3 is backfilled and constructed to form the river embankment 6 between the permeable protection cage 2 and the river bank, the top surface of the river embankment soil 3 is higher than the top surface height of the permeable protection cage 2, and the river embankment soil 3 forms a slope protection structure with a slope structure from the top surface to the top of the permeable protection cage 2, and the slope protection turf 4 is laid and planted on the slope protection structure of the river embankment soil 3.

[0023] The base layer 1 can be formed by pouring concrete or reinforced concrete, and is used to provide support for the stacking of the permeable protection cage 2. The permeable protection cage 2 is a cage structure, which is convenient for the passage of river water and forms a separation between the river embankment 6 and the river channel 5, so as to avoid the collapse of the river embankment soil 3 of the river embankment 6 and its slope protection structure.

[0024] At the same time, through the planting of the slope protection turf 4, the safety of the river embankment soil 3 can be further improved, the occurrence of collapse accidents can be reduced, and the service life of the entire river embankment slope protection device can be extended. Through the backfilling of the river embankment soil 3, the pouring of reinforced concrete dams is avoided, which can effectively reduce the construction investment and shorten the construction period.

[0025] Please refer to Appendix Figure 2 and Appendix Figure 3 , The described permeable protection cage 2 includes a protection cage body and pebbles installed in the protection cage body, and the particle size of the pebbles is larger than the mesh aperture of the protection cage body.

[0026] Preferably, the protection cage body can be made by binding and weaving galvanized iron wire, with high structural strength, long service life, and not easy to rust or corrode. The pebbles can be cobblestones slightly larger than the mesh aperture of the protection cage body, which can provide protection for the river embankment soil 3, avoid collapse and enable the river water to pass through the permeable protection cage 2.

[0027] Please refer to Appendix Figure 1 , The described base layer 1 is a concrete base layer, and the base layer 1 is constructed throughout the width direction of the river channel 5.

[0028] The length of the base layer 1 is adaptively constructed according to the length of the river embankment slope protection structure. The base layer 1 is completed by using the conventional construction technology of the river channel base layer, which will not be elaborated here.

[0029] A number of the described permeable protection cages 2 are sequentially stacked on the base layer 1 along the length direction of the base layer 1, so that a number of permeable protection cages 2 are arranged throughout the width direction of the river channel 5.

[0030] The single size and stacking quantity of the permeable protection cage 2 can be adaptively adjusted according to the length of the river embankment slope protection structure. Preferably, the length of a single permeable protection cage 2 is 3000mm, the height is 1000mm, and the width is 800mm.

[0031] The width of the permeable protection cage 2 is the same as that of the base layer 1, with one side of the permeable protection cage 2 facing the river channel 5 and the other side of the permeable protection cage 2 being in contact with the river embankment soil 3.

[0032] Preferably, the width of the base layer 1 is the same as that of the permeable protection cage 2, which is also 800 mm. The permeable protection cage 2 abuts against the river embankment soil 3. The self-weight of the permeable protection cage 2 is large and it is stacked stably, which can effectively prevent the collapse of the river embankment soil 3.

[0033] Please refer to the appendix Figure 1 , the top elevation of the described permeable protection cage 2 is higher than the lower elevation of the slope protection structure, thereby effectively preventing the collapse of the river embankment soil 3.

[0034] The described river embankment soil 3 includes base soil and planting soil. The planting soil is backfilled on the top of the base soil, and the slope protection turf 4 is laid and planted on the planting soil of the slope protection structure.

[0035] Preferably, the base soil can be the original river embankment soil, and the planting soil can be adaptively selected according to the planting requirements of the slope protection turf 4 to ensure the planting survival rate of the slope protection turf 4.

[0036] The height of the described planting soil is not less than 1 m, which is beneficial to further ensure the planting survival rate of the slope protection turf 4.

[0037] Please refer to the appendix Figure 1 to the appendix Figure 3 , the construction process of the present utility model is: concrete pouring for the base layer 1 → filling the protection cage main body with pebbles → backfilling the river embankment soil 3 → planting the slope protection turf 4.

[0038] Specifically, the concrete pouring for the base layer 1 includes: the base layer 1 is concretely poured in sections. After being vibrated densely, the flatness is checked according to the elevation control line, scraped flat with a wooden screed, and the surface is rubbed flat with a wooden float. If the base layer 1 has a slope requirement, slope according to the design requirement.

[0039] The concrete pouring construction of the base layer 1 is a conventional construction in the field, and the pouring and vibrating process thereof will not be elaborated here.

[0040] Filling the protection cage main body with pebbles includes: galvanized wire mesh cages are processed in the processing plant in advance as the protection cage main body. After being transported to the site, the protection cage main body is filled with cobblestones to form the permeable protection cage 2. The cobblestones are required to have a particle size larger than the mesh size of the protection cage main body to prevent the cobblestones from falling out. A plurality of permeable protection cages 2 are sequentially stacked on the base layer 1.

[0041] Backfilling the river embankment soil 3 includes: the base soil is required to be tamped layer by layer, and the planting soil is backfilled within 1 m below the surface layer to form the river embankment soil 3. The river embankment soil 3 is backfilled between the river bank and the other side surface of a plurality of permeable protection cages 2.

[0042] The earthwork backfilling construction of the river embankment soil 3 can be carried out by two excavators, and completed in cooperation with the corresponding earthwork transport vehicles and manual labor. The backfilling of the surface planting soil is mainly carried out manually. While mechanically filling and excavating the soil, sufficient manual labor should be allocated to do a good job in trimming the slope, and a special person should be assigned to track and measure the elevation of the soil body during the filling and excavation period. The river embankment soil 3 should reach the design elevation or be about 10 cm higher in the first stage.

[0043] The planting of the slope protection turf 4 includes:

[0044] (1) Use a robust lawn as the grass source. If the soil of the grass source is too dry, it should be irrigated before digging the grass. Dig out the grass roots, and it is best to bring some more native soil at the root. After digging, load and transport it away in time. Stack the grass in a shady place, the stack should be thin, and often spray water to keep the grass roots moist. If necessary, a shade shed can be set up for storage.

[0045] (2) The turf establishment is carried out by the method of dividing and planting grass roots and laying turf blocks. Select turf blocks from grass sources without weeds, good growth potential and no pests and diseases. Trim and spray water 24 hours before transplanting the slope protection turf 4, and suppress to keep the soil moist for better turf lifting.

[0046] (3) The specifications of the lifted turf should be preferably 30 cm × 30 cm, and the thickness should be controlled at 3 - 5 cm appropriately. Otherwise, it is not easy to transport, and it is also not easy for the roots of the slope protection turf 4 to combine with the original terrain soil and take root during laying.

[0047] The above is only the preferred embodiment of the present utility model, and is not used to limit the protection scope of the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
