Description

Technical Field

[0001] This application relates to a dam structure for preventing soil erosion. Background Technology

[0002] When constructing river embankments, the river itself has an impact and abrasive nature, necessitating structural reinforcement of the riverbanks to prevent soil erosion and potential hazards. Currently, a common method is to place stones or concrete blocks at the impact points to cushion the river's impact on the soil. This method presents three main problems: First, the placement is uneven, directly affecting the protective effect; second, it lacks stability, with some blocks being washed away into the riverbed during use; and third, it cannot support vegetation, failing to achieve the desired greening effect during the dry season, even for seasonal rivers. Utility Model Content

[0003] To address the aforementioned problems, this application proposes a dam structure for preventing soil erosion, comprising several layers of fixed units. Each fixed unit includes an impact-resistant block facing the river, a fixed connecting rod on the impact-resistant block, a reinforcing block on the fixed connecting rod, and an inner fixing plate on the side of the fixed connecting rod away from the impact-resistant block. This application uses the impact-resistant block as the unit directly facing the impact of river water, and the impact-resistant block is fixed at the rear by the fixed connecting rod and the reinforcing block, preventing displacement of the impact-resistant block after being impacted by the water flow.

[0004] Preferably, an auxiliary positioning block is provided at the lower part of the bottom shock-absorbing block.

[0005] Preferably, the outward-facing side of the impact-resistant block is arc-shaped, and adjacent impact-resistant blocks are joined at their cross-sections to form a green space for planting soil. This application utilizes arc-shaped impact-resistant blocks that abut against each other, naturally creating a green space for planting soil at the joint. For seasonal rivers, this allows for convenient greening during the dry season.

[0006] Preferably, the impact-resistant block is a sphere.

[0007] Preferably, the impact-resistant block is a concrete sphere or a stone sphere.

[0008] Preferably, the impact-resistant block and the reinforcing block are arranged in abutment.

[0009] Preferably, the reinforcing block comprises a rectangular box, with a wire mesh on the outside of the rectangular box, a plurality of counterweights inside the rectangular box, and gravel filling the spaces between the counterweights. This application uses a rectangular box enclosed by wire mesh, with internal counterweights, and after being buried in the soil, the foundation and the rectangular box are integrated, ensuring the overall structural integrity and stability after assembly.

[0010] Preferably, the counterweight is a counterweight stone.

[0011] Preferably, the counterweight includes a central concrete sphere, on which several outwardly extending concrete rods are provided.

[0012] Preferably, the fixed connecting rod is provided with a number of spaced-apart oblique positioning rods at the position corresponding to the rectangular box, and the oblique positioning rods are arranged perpendicular to the fixed connecting rod.

[0013] This application can bring the following beneficial effects:

[0014] 1. This application uses an anti-impact block as the unit that directly faces the impact of river water. The rear of the anti-impact block is fixed by a fixed connecting rod and a reinforcing block to prevent the anti-impact block from shifting after being impacted by water flow.

[0015] 2. This application uses an arc-shaped anti-impact block that abuts against the ground, and then naturally forms a green space at the abutment location where planting soil can be installed. For seasonal rivers, greening can be easily carried out during the dry season.

[0016] 3. This application uses a rectangular box enclosed by wire mesh, with internal counterweights. After being buried in the soil, the foundation and the rectangular box are integrated, ensuring the integrity and stability of the overall structure after assembly. Attached Figure Description
