This invention discloses a layered concrete structure with anti-penetration and filtering properties and its preparation method. It solves the problem in existing technologies where only the composition of the concrete layers is changed without improving the overall filtering performance. This invention has the beneficial effects of improving filtering performance and preventing further crack development. The specific solution is as follows: A layered concrete structure with anti-penetration and filtering properties includes a fiber-reinforced concrete layer and an intermediate composite material layer. The intermediate composite material layer is placed between two fiber-reinforced concrete layers. The fiber-reinforced concrete layer and the intermediate composite material layer are periodically arranged to form a layered concrete structure to enhance the filtering performance and improve the anti-penetration performance. The fiber-reinforced concrete layer contains steel fiber reinforcement to enhance the anti-penetration performance of the layered concrete structure. The wave transmittance in the intermediate composite material layer is different from that in the fiber-reinforced concrete layer, and the intermediate composite material layer is bonded to the fiber-reinforced concrete layer.

This utility model discloses an eco-board based on single mortise and tenon joint. The eco-board includes sub-wood strips and mother-wood strips, and the transverse direction of the eco-board is spliced ​​using mortise and tenon joints, while the longitudinal direction is spliced ​​using toothed joints. Its advantages are as follows: Compared with double mortise and tenon joints, the eco-board of this utility model, using a single mortise and tenon joint, has higher process efficiency and better economy. The processing time for single mortise and tenon joints can be reduced by 30%-50%, making it particularly suitable for mass production and requiring lower equipment precision. Secondly, it reduces the grooving process, lowering labor and tooling costs. Furthermore, the single mortise and tenon joint reduces material removal, making it suitable for scenarios requiring weight reduction (such as hanging cabinets and movable furniture). Moreover, the single mortise and tenon joint is particularly suitable for thin boards, requiring no larger board thickness for support, and can be used stably in eco-boards with a thickness of less than 18mm, thus broadening its application range.
