The main function is to block the soil and filter the seepage through the geotextile of the drainage shaped sheet self-adhesive geotextile, and drain the water through the overhead drainage channel in the drainage shaped sheet self-adhesive geotextile. The existing drainage shaped sheet self-adhesive geotextile includes a drainage shaped sheet body and a geotextile; the drainage shaped sheet body is composed of a plurality of support reinforcement columns arranged on a drainage flat plate and a drainage horizontal plate, and an overhead drainage channel is formed between the plurality of support reinforcement columns. It is applied to the waterproof layer and can become a flexible protective layer of the waterproof layer. The top of the support reinforcement column is coated with glue and bonded with the geotextile to improve the support strength of the adjacent support reinforcement columns and the geotextile.
