[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Example: Figures 1-4 The prefabricated slope protection device shown includes a flexible protective surface layer 1, which comprises a single layer of mesh geogrid, made of fiberglass geogrid. A single layer of puncture-resistant geotextile is provided at the upper end of the mesh geogrid, and a flexible waterproof board is provided at the upper end of the puncture-resistant geotextile. The mesh geogrid, puncture-resistant geotextile, and waterproof board are bonded together and can be rolled up and unrolled, providing waterproofing and reinforcement functions.

[0019] Furthermore, a flexible positioning layer is provided on the outer side of the flexible protective surface layer 1. The flexible positioning layer includes several positioning strips 2 made of flexible metal material, which can be rolled up and unfolded, so that the flexible protective surface layer 1 can be closely attached to the slope surface of the foundation pit, dividing the foundation pit slope surface into several stress units, effectively preventing the sliding of the soil on the foundation pit slope surface, and significantly improving the stability and stress resistance of the foundation pit slope surface.

[0020] Furthermore, the flexible protective surface layer 1 and the flexible positioning layer are fixedly connected to the slope through several fixing components 3. Each fixing component 3 includes two soil nails, the ends of which are connected as a whole by a U-shaped rod. The U-shaped rod is made of metal. By fixing the flexible protective surface layer 1 and the flexible positioning layer to the slope through the fixing components 3, a complete slope support surface is formed on the slope surface of the foundation pit, achieving the safety and stability of the foundation pit slope, thereby ensuring the smooth completion of the foundation pit project.

[0021] In practical application, the prefabricated slope support device places the flexible protective surface layer 1 on the foundation pit slope, uses a flexible positioning layer to press the flexible protective surface layer 1, and inserts several fixing pieces 3 in sequence, penetrating the flexible positioning layer 2 and the flexible protective surface layer 1 and extending into the soil of the foundation pit slope, forming a slope support structure with waterproof, protective and reinforcement functions.

[0022] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent solutions made using the contents of this utility model specification, whether directly or indirectly applied to other related technical fields, are also within the patent protection scope of this utility model.
