Description

Technical Field

[0001] The utility model relates to a cement blanket erosion ditch head protection structure. Background Art

[0002] The development of gully erosion mainly includes three aspects: first, gully head headward erosion; second, gully bank expansion; and third, gully bottom incision. Gully head protection is a measure to prevent gully head headward erosion, which can effectively control the advancement of gully head, prevent soil erosion, and protect arable land. Gully head protection can be divided into waterfall type gully head protection and pipeline energy dissipation type gully head protection. According to the different building materials used, waterfall type gully head protection can be divided into: willow waterfall, eco-bag waterfall, gabion waterfall, mortar stone waterfall, etc. Traditional gully head protection measures use plants, eco-bags, gabions and other materials to construct buildings on the basis of slope cutting and shaping to prevent gully head headward erosion, but there are two problems: first, the problem of land occupation caused by slope cutting. The gully head of the erosion gully is complex in shape and has a steep slope. Slope cutting and shaping are required to implement the measures, which involves land occupation; second, the process is relatively complex, and the construction details directly affect the function of the measures.

[0003] Cement blanket is a new type of material that combines cement and textiles. It has the characteristics of easy use, quick forming, durability, and environmental friendliness. It can be used to prevent and control soil erosion and play a role in reinforcement and reinforcement. Utility Model Content

[0004] The utility model aims to solve the technical problems that the current erosion ditch head protection slope cutting takes up space, requires slope cutting and shaping, and has complex processes, and provides a cement blanket erosion ditch head protection structure.

[0005] The cement blanket erosion ditch head protection structure of the utility model is to lay a cement blanket 1 on the surface of the ditch head near the steep slope 5, lay a cement blanket 1 on the surface of the steep slope 6, lay a cement blanket 1 on the surface of the ditch bottom near the steep slope 4, and lay cement blankets 1 on the ditch slopes on both sides of the above three cement blanket laying positions; all of the above cement blankets are fixed in corresponding positions by T-shaped nails 3; the cement blanket 1 on the ditch head is flush with the surface of the ditch head where the cement blanket is not laid;

[0006] A floodplain 2 is laid on the side of the cement blanket 1 at the bottom of the ditch away from the ditch head, and the floodplain 2 is higher than the cement blanket 1 at the bottom of the ditch. The cement blanket 1 extends to the bottom of the floodplain 2 along the direction of water flow.

[0007] The utility model first needs to remove the loose soil and debris on the surface of the ditch head and ditch slope to ensure that the base is smooth, and then lay the cement blanket. The cement blanket on the ditch head is flush with the surface of the ditch head where the cement blanket is not laid. After the cement blanket is laid, it needs to be watered and solidified, and the curing time is not less than 3 days. After the cement blanket is laid, the seabed is laid at the end of the cement blanket at the bottom of the ditch in the direction of the water flow to play the role of energy dissipation and anti-scouring.

[0008] The utility model adopts cement blanket for erosion ditch head protection, which has the advantages of adapting to complex ditch head shapes, requiring no slope cutting and occupying land, simple construction, low cost, and can quickly and effectively solve the problem of source erosion at the erosion ditch head.

[0009] This new cement blanket erosion ditch head protection system consists of two parts: the laying of the cement blanket and the downstream stone floodplain. After the cement blanket is laid, runoff is directed from the ditch head into the erosion ditch, controlling the head's forward movement. The downstream floodplain dissipates runoff energy, acting as a transition and buffer. This new system primarily focuses on compaction and leveling, significantly reducing the difficulty and cost of repairing the ditch head.

[0010] The utility model is a medium slope protection solidifying cement blanket which is applied to soil slopes, hillsides, garden greening and other projects to provide slope protection and stabilization functions. BRIEF DESCRIPTION OF THE DRAWINGS
