Example Embodiment
[0016] Embodiment 1: A method for manufacturing a cement-based wood chip composite sound barrier, characterized in that: first, wood chip particles, glue, cement, water and yellow sand are mixed in a certain proportion to form a wood chip mixture; half of the wood chip mixture is injected into a mold Flatten it, put it into the steel mesh, and then inject the rest of the wood chip mixture into the mold to be flat; then inject the cement concrete mixture, hold the pressure for 18 hours under the pressure of 450T, and finally demold it to form a cement-based wood chip composite sound barrier.
Example Embodiment
[0017] Embodiment 2: a method for manufacturing a cement-based wood chip composite sound barrier, characterized in that: first, wood chip particles, glue, cement, water and yellow sand are mixed in a certain proportion to form a wood chip mixture; half of the wood chip mixture is injected into the mold Lay it out, put it into the steel mesh, and then inject the rest of the wood chip mixture into the mold to spread it out; then inject the cement concrete mixture, hold it for 30 hours under a pressure of 500T, and finally demold it to form a cement-based wood chip composite sound barrier.
Example Embodiment
[0018] Embodiment 3: a method for manufacturing a cement-based wood chip composite sound barrier, characterized in that: firstly, the wood chip mixture is formed by mixing wood chip particles, glue, cement, water and yellow sand in a certain proportion; half of the wood chip mixture is injected into the mold Lay it flat, put it in the steel mesh, and then inject the rest of the wood chip mixture into the mold to spread it out; then inject the cement concrete mixture, keep it under pressure of 480T for 24 hours, and finally demold it to form a cement-based wood chip composite sound barrier.
