High-strength antibacterial jacking pipe and preparation method thereof
According to the high-strength antibacterial jacking pipe and the preparation method thereof, unsaturated resin serves as a continuous phase, waste fibers in the unsaturated resin serve as a reinforcing agent, stone waste powder serves as a filling phase, waste fiber reinforced and modified resin concrete is formed, and the jacking pipe with high initial axial compression strength and external pressure breaking strength and the jacking pipe with the antibacterial function are prepared. The initial axial compression strength is larger than or equal to 80 MPa, the external pressure breaking strength and the minimum-specification pipe jacking index are larger than or equal to 25000N/m, the escherichia coli and staphylococcus aureus resistance is larger than or equal to 90%, the compression resistance requirement of special geology can be met, bacterial virus spreading is avoided, and a clean and comfortable urban environment can be built.
本发明提供一种高强度抑菌型顶管及其制备方法，以不饱和树脂为连续相、不饱和树脂中的废纤维为增强剂、石材废粉为填充相，形成废纤维增强改性的树脂混凝土，制得具备高初始轴向压缩强度、外压破坏强度顶管以及抗菌功能的顶管，初始轴向压缩强度≥80MPa，外压破坏强度，最小规格顶管指标≥25000N/m，抗大肠杆菌和金黄色葡萄球菌能力均≥90％，能够满足特殊地质的抗压需求，避免细菌病毒散播，有利于营造洁净、舒适的城市环境。
