[0002] In road engineering, in order to protect the road surface, anti-seepage structures are generally installed to protect the roads. This mainly involves preventing the penetration of rainwater and groundwater during road construction and maintenance to prevent road surface subsidence and collapse, as well as protecting groundwater resources.

[0003] After searching, the patent number is CN213951816U, and the name is a utility model of a road anti-seepage structure, including a base layer. Through research and analysis, it is found that although it is waterproof and water-absorbing, it still has the following disadvantages to a certain extent.

[0004] For example, the structure does not have the function of multi-layer anti-seepage protection. When the single waterproof layer is damaged, it relies on the water-absorbing layer to lock the water, overly relying on the water-absorbing material and the thickness of the water-absorbing layer, and does not have the function of auxiliary water drainage. The hole-shaped design is used in external roads, which is prone to blockage and affects the overall drainage performance of the structure. In order to solve the above technical problems, we designed a road durable anti-seepage structure. Utility Model Content
