摘要
盾构始发接收为盾构隧道施工工法的重难点,工法桩围护结构作为盾构始发接收洞门增加了该工序的施工风险,针对此,分析了盾构接收施工中存在的风险,介绍了工法桩围护结构施工洞门的措施以及接收方法,从而加强了盾构施工安全性,减少盾构施工约束性,保证盾构接收顺利完成.
Abstract
As a matter of fact,shield originating and receiving is a critical and difficult point in shield tunneling construc-tion.However,SMW enclosure structure is regarded as the shield originating and receiving tunnel entrance,which increa-ses its construction risk.Based on the above-mentioned construction conditions,the paper analyzes risks existing in shield originating and receiving process,introduces the tunnel entrance processing measures and receiving methods of SMW en-closure structure.As a result,it not only strengthens the shielding construction safety,but also reduces shielding con-struction limit,and ensures smooth shield receiving as well.
