Description

Technical Field

[0001] This utility model relates to the field of foundation pit slope protection technology, specifically a special laying device for flexible concrete composite mats. Background Technology

[0002] Flexible concrete composite mats, also known as cement blankets, are blanket-like waterproof rolls made from a mixture of dry concrete, woven fabric, and polyester non-woven fabric. Dry concrete particles are fixed between the non-woven and woven fabric layers using a needle-punching method. After absorbing water, the dry concrete solidifies into a unified slope protection material within the limited space between the top and bottom layers of non-woven fabric. Currently, flexible concrete composite mats are generally laid manually. However, in cases of soft or uneven slopes, manual laying results in poor adhesion to the slope, making it difficult to ensure uniformity and continuity, thus creating safety hazards.
