Abstract
Description
Technical Field
[0001] This invention belongs to the field of ecological bank protection technology, and in particular relates to a construction method for gabion ecological bank protection. Background Technology
[0002] The Tarim River, located in my country's arid inland region, is the country's longest inland river. Its water source is primarily meltwater from high-altitude glaciers and snowmelt. It is characterized by summer floods and winter droughts, a fragile ecosystem, and severe desertification along its course. It is renowned worldwide for its unique topography and ecological desertification. Historically, the Tarim River was a notorious wandering river in the desert region. Its riverbed boundary materials have weak erosion resistance, the surrounding soil is mostly fine sand, vegetation cover is low, and it is significantly affected by wind and sand, resulting in poor riverbed control over the flow. This is particularly evident in the section upstream of Xinqiman, specifically the section from Alar to Luchang in Shaya County, where the central channel is wide and shallow, numerous mid-channels and distributaries crisscross the river, and the main stream is unstable, exhibiting clear wandering characteristics.
[0003] A key characteristic of the horizontal evolution of wandering rivers is the unpredictable shifting of the main channel and dramatic changes in river course. Because the riverbed boundaries are often composed of easily eroded fine sand, especially during the flood season, the riverbed experiences significant silting and scouring, resulting in large longitudinal erosion and deposition amplitudes and intense lateral swaying. Since wandering rivers are often above-ground, they face significant flood control challenges. Therefore, there is an urgent need for researchers to develop a method to prevent river channel shifting in desert areas and to achieve ecological bank protection through vegetation planting. Summary of the Invention
[0004] In view of this, the present invention provides a construction method for gabion ecological revetment to solve the above problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A construction method for gabion ecological revetment includes the following steps:
[0007] S1. Choose a relatively dry season and excavate overflow channels on both sides of the river following the river's course;
[0008] S2. Lay multi-level stepped gabions between the river channel and the overflow trough;
[0009] S3. Plant shrubs and protective forests in sequence on the outside of the overflow channel of the DC river, and dig multiple first irrigation ditches outward from the overflow channel. The first irrigation ditches provide water for the shrubs and protective forests.
[0010] S4. Excavate the first reservoir and connecting ditch on the outside of the bend of the river, and connect the overflow ditch and the first reservoir.
[0011] S5. Excavate second irrigation ditches on both sides of the first reservoir. The second irrigation ditches are connected to multiple first irrigation ditches. Install a water pump next to the first reservoir to pump out the stored water in the first reservoir and provide water to the shrubs and shelterbelts outside the river through the second irrigation ditches and multiple first irrigation ditches.
[0012] Furthermore, in step S1, when excavating the overflow trough, the outer side of the overflow trough is higher than the bottom surface of the gabion and lower than the top surface of the gabion, so that the overflow trough has water storage capacity.
[0013] Furthermore, in step S1, paving stones are laid inside the overflow trough, and cement is applied to the surface of the paving stones to prevent the overflow trough from collapsing and the water in the overflow trough from seeping into the soil.
[0014] Furthermore, in step S2, a filter screen is laid on the river side of the multi-tiered stepped gabion to prevent sand in the river from entering the overflow trough through the gabion.
[0015] Furthermore, in step S4, multiple plastic pipes are laid at intervals at the bottom of the river bend, so that the plastic pipes connect the overflow channels on both sides of the river.
[0016] Furthermore, in step S4, a second reservoir and a connecting ditch are excavated on the inner side of the river bend, and the overflow ditch, the connecting ditch and the second reservoir are connected.
[0017] Furthermore, second irrigation ditches were excavated on both sides of the second reservoir. The second irrigation ditches were connected to multiple first irrigation ditches. A water pump was installed next to the second reservoir to pump out the stored water from the second reservoir and provide water to the shrubs and shelterbelts on the inner side of the river through the second irrigation ditches and multiple first irrigation ditches.
[0018] The beneficial effects of this invention are as follows:
[0019] 1. Gabions can prevent river channels in desert areas from shifting. During the rainy season, when the water rises, the river water flows through the filter screen on the gabions into the overflow trough. When the water rises further, it irrigates the shrubs and shelterbelts through the first irrigation ditch. The excess water then flows into the first and second reservoirs through the second irrigation ditch.
[0020] 2. When the river flows through the bend, the river water will impact the outer gabion cages. After being filtered, the river water flows into the overflow trough and then through the plastic pipe at the bottom into the inner overflow trough of the bend, reducing the scouring of the outer side of the bend.
[0021] 3. When the river flow is too large at the bend, it can flow into the first and second reservoirs through connecting channels for flood discharge and water storage. During the dry season, when there is a water shortage, water pumps are used to irrigate the shrubs and shelterbelts through the second and first irrigation ditches. Attached Figure Description

[0029] Example 1
[0030] See attached document Figure 1-3 As shown, the present invention provides a construction method for gabion ecological revetment, comprising the following steps:
[0031] S1. In a relatively dry season, excavate overflow channels 2 on both sides of the river channel 1 following the river's course. After excavating the overflow channels 2, lay bricks inside the overflow channels 2 and apply cement to the surface of the bricks to prevent the overflow channels 2 from collapsing and to prevent water in the overflow channels 2 from seeping into the soil. Furthermore, the outer side of the overflow channels 2 should be higher than the bottom surface of the gabion 3 and lower than the top surface of the gabion 3, so that the overflow channels 2 have a certain water storage capacity.
[0032] S2. Lay a multi-stage stepped gabion 3 between the river channel 1 and the overflow channel 2. Lay a filter screen 10 on the river side of the multi-stage stepped gabion 3 to prevent sand in the river from entering the overflow channel 2 through the gabion 3.
[0033] S3. Plant shrubs 4 and shelterbelts 5 in sequence on the outside of the overflow channel 2 of the direct current channel 1, and dig multiple first irrigation ditches 6 outward from the overflow channel 2. The first irrigation ditches 6 provide water for the shrubs 4 and shelterbelts 5.
[0034] S4. Excavate the first reservoir 7 and connecting ditch 8 on the outer side of the river bend, and connect the overflow ditch 2, connecting ditch 8 and the first reservoir 7; at the same time, lay multiple plastic pipes 11 at intervals at the bottom of the river bend, so that the plastic pipes 11 connect the overflow ditch 2 on both sides of the river channel 1; and excavate the second reservoir 12 and connecting ditch 8 on the inner side of the river bend, and connect the overflow ditch 2, connecting ditch 8 and the second reservoir 12.
[0035] S5. Excavate a second irrigation ditch 9 on both sides of the first reservoir 7. The second irrigation ditch 9 is connected to multiple first irrigation ditches 6. A water pump is installed next to the first reservoir 7. The water pump is used to pump out the water stored in the first reservoir 7 and provide water to the shrubs 4 and shelterbelts 5 outside the river channel 1 through the second irrigation ditch 9 and multiple first irrigation ditches 6.
[0036] Second irrigation ditches 9 are excavated on both sides of the second reservoir 12. The second irrigation ditches 9 are connected to multiple first irrigation ditches 6. A water pump is installed next to the second reservoir 12 to pump out the water stored in the second reservoir 12 and provide water to the shrubs 4 and shelterbelts 5 on the inner side of the river channel 1 through the second irrigation ditches 9 and multiple first irrigation ditches 6.
[0037] The gabion 3 of the present invention can prevent the river channel 1 in the desert area from shifting. When the water rises during the rainy season, the river water flows through the filter screen 10 on the gabion 3 into the overflow trough 2. When the river water rises further, it irrigates the shrubs 4 and the shelter forest 5 through the first irrigation ditch 6. The excess water then flows into the first reservoir 7 and the second reservoir 12 through the second irrigation ditch 9.
[0038] When the river flows through the bend, the river water will impact the outer gabion 3. After being filtered, the river water flows into the overflow trough 2, and then flows through the plastic pipe 11 at the bottom into the inner overflow trough 2 of the river bend, reducing the scouring of the outer side of the bend.
[0039] When the river flow is too large at the bend, it can flow into the first reservoir 7 and the second reservoir 12 through the connecting channel for flood discharge and water storage. During the dry season when there is a water shortage, water pumps are used to irrigate the shrubs 4 and the shelterbelts 5 through the second irrigation ditch 9 and multiple first irrigation ditches 6.
