Mold for laying granular seepage-proofing materials

The utility model relates to a mold for laying granular seepage-proofing materials. The mold comprises a rectangular frame, a bottom plate with holes and at least two limiting blocks arranged on the outer sides of two adjacent edges of the frame, the surface of the frame and the surface of the bottom plate are sequentially coated with a binder layer and a tectorial quartz sand layer, and the surface of the frame and the surface of the bottom plate are both of a wavy structure. The mold for laying granular seepage-proofing materials can lay granular seepage-proofing materials rapidly and stably, has the advantages of being easy and convenient to apply and good in effect, construction efficiency is improved greatly, and manpower, material resources and time cost are saved. Meanwhile, due to the fact that the tectorial quartz sand layer has strong hydrophobicity, and the interfacial effect between the tectorial quartz sand layer and the granular seepage-proofing materials is low, water cannot permeate through clearances between the mold and the granular seepage-proofing materials.
