Description

Technical Field

[0001] This utility model relates to the field of riverbank erosion control technology, specifically a willow stake bank protection for erosion gully control. Background Technology

[0002] Riverbank erosion gullies are linear, trough-shaped depressions formed by continuous downcutting, lateral erosion, and subsequent headward and process-related erosion. They primarily occur on loose sedimentary layers in semi-arid climate zones. This type of erosion landform is the result of temporary water erosion and damage to the land surface, typically developing in sparsely vegetated, gently sloping areas. It easily leads to significant soil and water loss, making erosion gully management an important measure for promoting ecological civilization. Through comprehensive management of soil and water loss, the ecological environment can be improved, and the sustainable use of land resources can be achieved.

[0003] Existing methods for protecting riverbanks with erosion gullies often involve using a single wooden pile arrangement to block soil erosion. However, these piles are easily eroded by the long-term flow of the river, resulting in a limited lifespan for the protection of the riverbank. Therefore, this method does not meet the current needs. To address this, we propose a willow pile bank protection method for erosion gully control. Utility Model Content

[0004] The purpose of this utility model is to provide a willow pile bank protection for gully control, in order to solve the problem mentioned in the background art that when protecting riverbanks with gullies, a single wooden pile is often used to block soil erosion, which is easily eroded by the long-term flow of river water and has a limited lifespan for the protection of the riverbank.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a willow stake revetment for gully erosion control, comprising a barrier net, a connecting horizontal bar fixedly installed at the upper end of the barrier net, multiple hook units installed on the outer side of the connecting horizontal bar, a second isolation frame installed on the outer side of the upper end of the hook unit, a positioning notch provided in the middle of the second isolation frame, a backfill layer installed on the rear end face of the barrier net, a first row of willow stakes and a second row of willow stakes installed on the inner side of the backfill layer, the first row of willow stakes being located in front of the second row of willow stakes, the first row of willow stakes being composed of multiple first willow stakes, and the second row of willow stakes being composed of multiple second willow stakes and third willow stakes.

[0006] Preferably, the plurality of first, second, and third willow stakes are arranged linearly, the plurality of second and third willow stakes are installed alternately, the bottom ends of the plurality of first, second, and third willow stakes penetrate the bottom ends of the backfill layer and the barrier net, and each first willow stake is staggered with the second and third willow stakes.

[0007] Preferably, each of the third willow stakes is connected to a first isolation frame between it and two adjacent first willow stakes, and a second isolation frame is installed between the two adjacent first isolation frames on the inner side of the two first willow stakes. The multiple first isolation frames and second isolation frames are arranged alternately and staggeredly, and the bottom ends of the multiple first isolation frames and second isolation frames are all connected to the inner side of the backfill layer.

[0008] Preferably, the hook unit includes a fixing block, a connecting rope is fixedly installed on the inner side of the fixing block, and a tapered connector is installed on the outer side of the upper end of the connecting rope.

[0009] Preferably, the bottom end of the positioning notch is provided with a positioning hole, the positioning notch is connected to the positioning hole, one end of the conical connector passes through the positioning hole and is fixedly connected to the upper end of the connecting rope, the conical connector is fixedly connected to the fixing block by the connecting rope, and the barrier net is fixedly connected to multiple hook units by connecting crossbars.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model lays the bottom end of the barrier net at the bottom edge of the riverbank. The bottom ends of multiple first, second, and third willow stakes penetrate the bottom end of the barrier net and are inserted into the inner side of the riverbank. Then, multiple first and second isolation frames are staggered and alternately inserted between the first and second rows of willow stakes. This effectively seals the gaps between the multiple first, second, and third willow stakes, isolating the river water from the riverbank and preventing the river water from eroding the riverbank and forming erosion gullies. At the same time, the backfill soil layer protects the willow stakes from river water erosion and extends the lifespan of the willow stakes protecting the riverbank.

[0012] 2. This utility model has a positioning hole at the bottom of the positioning notch. The conical connector is placed inside the positioning hole through the guide of the positioning notch. Under the limiting action of the second isolation frame, multiple conical connectors can pull the connecting crossbar at multiple points through the connecting rope and fixing block. This facilitates the stability of the barrier net by multiple hook units through the connecting crossbar, and backfilling between the barrier net and the riverbank. The barrier net can protect and shape the backfill layer, keeping the backfill layer covering the first and second willow pile rows, and reducing the erosion of the first and second willow pile rows by the river water.

The multiple first willow stake poles 7, second willow stake poles 8 and third willow stake poles 9 can protect the riverbank while ensuring the stability of the barrier net 1.

[0021] Please see Figure 3 and Figure 4Each third willow stake 9 is connected to a first isolation frame 10 between it and two adjacent first willow stakes 7. A second isolation frame 11 is installed between two adjacent first isolation frames 10 on the inner side of the two first willow stakes 7. The multiple first isolation frames 10 and second isolation frames 11 are arranged alternately and staggered. The bottom ends of the multiple first isolation frames 10 and second isolation frames 11 are all inserted into the inner side of the backfill layer 6. The multiple first isolation frames 10 and second isolation frames 11 can effectively seal the gaps between the multiple first willow stakes 7, second willow stakes 8 and third willow stakes 9, effectively preventing the riverbank from being eroded and forming erosion gullies when the river flows.

[0022] Please see Figure 1 , Figure 3 and Figure 4 The hook unit 3 includes a fixing block 15, a connecting rope 14 is fixedly installed on the inner side of the fixing block 15, a tapered connector 13 is installed on the outer side of the upper end of the connecting rope 14, a positioning hole is provided at the bottom end of the positioning notch 12, the positioning notch 12 is connected to the positioning hole, one end of the tapered connector 13 passes through the positioning hole and is fixedly connected to the upper end of the connecting rope 14, the tapered connector 13 and the fixing block 15 are fixedly connected by the connecting rope 14, the barrier net 1 and multiple hook units 3 are fixedly connected by connecting crossbars 2, so that multiple hook units 3 can maintain the stability of the barrier net 1 by connecting crossbars 2, and backfill the backfill layer 6 between the barrier net 1 and the riverbank, thereby protecting and shaping the backfill layer 6 through the barrier net 1.

[0023] In summary, when treating riverbank erosion gullies, the bottom of the barrier net 1 is laid at the bottom edge of the riverbank. Then, the first row of willow stakes 4 and the second row of willow stakes 5 are installed in sequence. Multiple second willow stakes 8 and third willow stakes 9 are arranged alternately, so that the bottom ends of multiple first willow stakes 7, second willow stakes 8 and third willow stakes 9 all penetrate the bottom of the barrier net 1 and are inserted into the inner side of the riverbank.
