AI Technical Summary
Technical Problem
[0003]钢筋混凝土管是最传统的顶管管材之一，优点是抗压强度高，生产工艺成熟，原材料成本相对较低；然而，其自重极大，给运输、吊装和施工带来了巨大的负担，增加了设备和能源消耗，其次，其为脆性材料，抗弯和抗剪性能较差，在复杂地质条件下或遭遇不均匀沉降时，容易开裂破损，再者，混凝土管的接头密封难度较大，易发生渗漏，最后，在面对高腐蚀性土壤或输送工业污水时，混凝土的耐化学腐蚀性能不足，使用寿命受限
Benefits of technology
1.以外部合金外壳作为主要承力结构，确保了管材具备足够的轴向抗压强度和径向刚度，能够承受严苛的顶管施工载荷，内部采用低密度的木纤维复合材料作为芯体，大幅降低了管材的整体重量，与同等强度的实心钢管或钢筋混凝土管相比，减重效果显著，降低了运输成本，减轻了现场吊装设备的负荷，提高了施工效率。
