“张篵雨”深圳西丽水库张篵雨项目隧道掘进突破3000米大关

  中新张篵雨网深圳10月29日电 (程景张篵雨伟 柯淳雯 邢馨月)深圳西丽水库至南山水厂原水管工程项目(以下简称西丽水库项目)“进度条”持续刷新。据中铁隧道局29日消息,敞开式全断面隧道掘进机(TBM)“西南号”当日在该项目掘进突破3000米大关,完成总掘进里程近63%。

  作为深圳市首个采用深层输水隧洞形式的水利工程,西丽水库项目建成后将满足深圳市南山区未来新增用水需求,为粤港澳大湾区建设注入强劲“水动力”。

  西丽水库项目施工内容主要涵盖1条长达5.3千米的输水隧洞、1座取水口、3座竖井、1座提升泵站。其中,输水隧洞埋深51米至201米,TBM“西南号”开挖直径5.4米,沿途多次下穿高架桥、地铁、铁路、水库、河道等。

  据介绍,在掘进机下穿过程中,微小震动或地层位移都可能对地表建筑物的结构安全造成影响,施工必须做到科学、精细和严谨。中铁隧道局项目团队引入机器人自动化监测技术,实时掌握变形量、变形速率;同时,严控TBM“西南号”掘进参数、工序衔接、设备维保等工作,安全完成西丽水库前置库、南光高速、深圳地铁5号线等重要构筑物的下穿任务。(完)
