近日，珠江三角洲水资源配置工程B3标“粤海37号”盾构机创下单班掘进10环（16米）、日掘进18环（28.8米）的新纪录。
“粤海37号”为开挖直径8.65米的泥水盾构机，盾构区间长度3196米，段洞身岩土体为弱风化泥质粉砂岩类，下穿狮子洋水道穿过多条断层破碎带，地质条件复杂。为了确保盾构机顺利、快速掘进，项目通过超前决策、优化施工方案、召开专家会议等举措攻克了分体始发场地面积不足、仓内积渣、盾构刀盘管理等难题，过程中不断总结提升，极大地提高了施工效率。
截至目前，“粤海37”号已掘进600米。下一步，项目将根据当地疫情防控政策提前筹划施工安排、合理调整资源配置，狠抓生产安全不放松、疫情防控不放松，持续保持稳产高产态势，开启项目工程建设新征程。
