Description

Technical Field

[0001] This utility model relates to the field of river ecological management technology, and in particular to an ecological soil and water conservation structure for river embankments. Background Technology

[0002] River embankments are key engineering facilities for resisting water erosion and protecting the land along the river. Their soil and water conservation effect directly affects the stability of the river ecosystem and the safety of the riverbanks.

[0003] The current embankment structure is a simple ecological structure, such as grass-planted slope protection and geogrid slope protection. Although the concept of vegetation restoration has been introduced, there are still functional shortcomings: the survival rate of vegetation is low, the surface soil of the embankment is easily washed away by rainwater or water flow, resulting in the exposure and death of seedling roots. In addition, the erosion resistance is insufficient, and it relies only on the surface vegetation to stabilize the soil. When facing seasonal floods, the surface soil of the embankment is easily hollowed out, forming gullies, which prevents the vegetation from forming a stable ecological community. Utility Model Content

[0004] The purpose of this utility model is to provide an ecological soil and water conservation structure for river embankments, aiming to solve the technical problems in the prior art where the surface soil of the embankment is easily eroded by rainwater or water flow, resulting in the exposure and death of seedling roots and the surface soil of the embankment is easily hollowed out, forming gullies, which prevents vegetation from forming a stable ecological community.

[0005] To achieve the above objectives, this utility model adopts an ecological soil and water conservation structure for river embankments, comprising an embankment body, with a uniformly distributed grid fixedly installed on the upper part of the embankment body. The grid contains, from bottom to top, a concrete filling block, a gravel filter layer, a permeable cloth, an elastic pad, an anti-erosion guard plate, a root-fixing grid, and an ecological planting box. A first drainage pipe is laid in the gravel filter layer, and the first drainage pipe penetrates the grid. The upper surface of the first drainage pipe is provided with multiple seepage grooves.

[0006] The grid is fixedly installed with a connecting embankment block on the embankment top side near the embankment body, and one end of the first drainage pipe is fixedly installed inside the connecting embankment block.

[0007] The upper surface of the connecting embankment is provided with multiple water diversion channels that are connected to the first drainage pipe.

[0008] The embankment body has a U-shaped ditch at the top and a filter baffle above it.

[0009] The U-shaped ditch is connected to a second drainage pipe, the other end of which passes through the toe of the embankment body.

[0010] The grid is fixedly provided with a limiting embankment block on the embankment toe side near the embankment body, and the other end of the first drainage pipe passes through the limiting embankment block.

[0011] The outer surface of the toe of the embankment body is covered with a protective layer, which is fixed to the outer surface of the toe of the embankment body by fixing nails.

[0012] The lower end of the protective layer is fixedly provided with a positioning post, which is fixed to the bottom of the river.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] 1. The special substrate of the ecological planting box prevents soil erosion and loss, and the expandable root-fixing mesh wraps around and fixes the root system to prevent the vegetation from being exposed and dying. The pores of the concrete filling block provide habitat for microorganisms and roots. At the same time, the expandable permeable cloth and the permeable holes of the ecological planting box work together to regulate humidity, avoid waterlogging or drought, and effectively ensure the survival rate of vegetation.

[0015] 2. The anti-scouring plate directly blocks the impact of water flow, and the elastic pad absorbs the impact energy to reduce structural damage; the grid and the concrete filling block form a rigid skeleton to inhibit soil slippage; the protective layer at the toe of the dike resists the scouring of river water and prevents the toe of the dike from becoming unstable.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] In this embodiment, a uniformly distributed grid 102 is fixedly installed above the embankment body 101. From bottom to top, the grid 102 contains a concrete filling block 103, a gravel filter layer 104, a permeable cloth 105, an elastic pad 106, an anti-erosion guard plate 107, a root-fixing mesh 108, and an ecological planting box 109. A first drainage pipe 110 is laid within the gravel filter layer 104, penetrating the grid 102. Multiple seepage grooves 1101 are provided on the upper surface of the first drainage pipe 110. The grid 102 is fixed to the inclined surface of the embankment body 101 by reinforcing bars. The concrete filling block 103 is made of porous lightweight ecological concrete, and herbaceous plant seeds can be implanted inside to enhance the ecological and structural stability of the grid 102 area, effectively improving the stability of the grid 102. The gravel filter layer 104 fills the area around the first drainage pipe 110, without using pebbles, effectively filtering impurities in the water. The permeable cloth 105 is laid on the surface of the gravel filter layer 104 to effectively filter the silt in the infiltrated water and prevent the first drainage pipe 110 from being blocked. The elastic pad 106 is made of rubber to absorb the impact energy of the water flow on the anti-erosion plate 107 and reduce structural vibration damage. The anti-erosion plate 107 is made of polyethylene board with permeable holes on the surface to block the water flow from directly eroding the slope soil, while allowing rainwater to infiltrate to the lower layer. The root-fixing grid 108 is laid under the ecological planting box 109 to wrap and fix the plant roots to prevent the roots from falling off due to the impact of the water flow. The ecological planting box 109 is made of plastic and filled with a mixture of humus and river sand to fix the plant roots, prevent the substrate from being lost, and provide growth space for the plants. This can effectively prevent the surface soil of the embankment from being eroded and ensure that the vegetation can grow stably.

[0025] The grid 102 is fixedly provided with a connecting embankment block groove 111 on the embankment top side near the embankment body 101, and one end of the first drainage pipe 110 is fixedly provided in the connecting embankment block groove 111, and the connecting embankment block groove 111 fixes one end of the first drainage pipe 110.

[0026] Secondly, the upper surface of the connecting embankment block groove 111 is provided with a plurality of water diversion channels 1111 that are connected to the first drainage pipe 110. The water diversion channels 1111 guide the water on the surface of the connecting embankment block groove 111 into the first drainage pipe 110, and the water on the embankment body 101 near the top of the embankment washes the area of ​​the grid 102 below.

[0027] Meanwhile, a U-shaped ditch 112 is provided at the top of the embankment body 101, and a filter baffle 113 is provided above the U-shaped ditch 112. The U-shaped ditch 112 collects water at the top of the embankment body 101, and the filter baffle 113 prevents silt from entering the U-shaped ditch 112.

[0028] In addition, a second drainage pipe 114 is connected inside the U-shaped ditch 112. The other end of the second drainage pipe 114 passes through the foot of the embankment body. Water in the U-shaped ditch 112 is discharged into the river channel at the foot of the embankment body through the second drainage pipe 114, thus preventing water accumulation in the U-shaped ditch 112.

[0029] Secondly, a limiting block 115 is fixedly installed on the side of the grid 102 near the toe of the embankment body 101, and the other end of the first drainage pipe 110 passes through the limiting block 115. The limiting block 115 fixes the other end of the first drainage pipe 110, and the grid 102 is fixed by the cooperation between the limiting block 115 and the connecting block groove 111, which effectively prevents the grid 102 from settling and deforming due to the tilt angle and improves the stability of the structure.

[0030] Meanwhile, a protective layer 116 is laid on the outer surface of the toe of the embankment body 101. The protective layer 116 is fixed to the outer surface of the toe of the embankment body 101 by the fixing nails 117. The protective layer 116 is a geotextile composite concrete slab, which has both impermeability and erosion resistance, and can directly block the water flow from eroding the toe of the embankment body 101.

[0031] In addition, a positioning post 118 is fixedly installed at the lower end of the protective layer 116. The positioning post 118 is fixed to the bottom of the river channel and is vertically implanted into the bottom of the river channel to provide longitudinal fixing force for the protective layer 116, so as to prevent the protective layer 116 from shifting as a whole under the lateral thrust of the water flow and to ensure the long-term stability of the toe protection of the embankment body 101.

[0032] Using the riverbank ecological soil and water conservation structure of this embodiment, by setting the grid 102, the telescopic anti-scour protection plate 107 and the ecological planting box 109, in specific use, the ecological planting box 109 provides vegetation growth, the root-fixing grid 108 can make the vegetation root system more stable and prevent the root system from shifting when the vegetation is scourted, and the elastic pad 106 absorbs the impact energy of the river water on the anti-scour protection plate 107. The river water flows down into the permeable cloth 105 layer through the permeable holes of the anti-scour protection plate 107. The permeable cloth 105 blocks the silt in the river water, so that the river water flows down to the gravel filter layer 104 and flows into the first drainage pipe 110 through the infiltration channel 1101, so that the river water flows out from the restrictive embankment block 115. In this way, the survival rate of vegetation can be effectively improved, the surface soil of the embankment can be avoided, and the vegetation can be stably ensured to form a stable ecological community.

[0033] The above-disclosed embodiments are merely preferred embodiments of the ecological soil and water conservation structure for riverbanks of this utility model, and should not be construed as limiting the scope of this utility model. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this utility model, still fall within the scope of this utility model.
