摘要

以深圳地铁3151标益田站至石厦站盾构区间联络通道施工为例，介绍了联络通道及废水泵房的施工难点，根据工程实际情况，对方案进行了优化，采用全断面注浆加固地层的方式代替旋喷桩土体注浆加固，重点介绍了全断面注浆加固止水的施工工艺及技术要点。方案优化后，保证了不良地质条件下隧道联络通道的顺利进行。

Abstract

The construction difficulties of connection galleries and waste water pump room are presented, with the construction of connection galleries of shieldbored tunnel on Yitian stationShixia station section of 3151 bid section of Shenzhen Metro as an example. Jet grouting reinforcement technology is replaced by fullface grouting reinforcement technology. The construction technology and technical key points of fullface grouting reinforcement technology are presented. The successful construction of connection galleries of shieldbored tunnel under bad geological conditions is guaranteed after construction program optimization.

Key words： tunnel; connection gallery; shieldbored tunnel section; grouting; support; secondary lining
