双护盾TBM超前支护系统设计

Design of Advanced Support System for Double Shield TBM

双护盾隧道掘进机(简称双护盾TBM)具有施工安全高效的优势,在隧道施工中得到广泛应用。本文首先分析了双护盾TBM配置超前支护系统的必要性和隧道施工中常用的几种超前支护方案。然后,重点介绍了双护盾TBM超前支护系统总体方案设计、超前钻机及注浆设备的选型。双护盾TBM超前支护系统在工地进行了实际应用并取得了良好的效果,顺利通过了用户的现场验收。

Double shield tunnel boring machine (shorted for double shield TBM) was widely used in tunnel construction, because of its advantage of safety and high efficiency. The necessity of designing an advanced support system for the double shield TBM was analyzed as well as several normally used advanced support schemes. Then, the overall design of advanced support system as well as selection of advanced driller and grout injection equipment was introduced. The advanced support system of the double shield TBM was applied successfully in jobsite, and passed the acceptance of customer.
