| Abstract: | For the safety of tunnel collapse construction,long pipe roof was constructed in the tunnel.The long pipe roof 'obliquity is relatively big.Under the protect of the long pipe roof,advance grouting and radial small duct grouting was constructed.After the grouting,one 4m-thichness protecting shield was formed to bear the weight of tunnel top.By the assistant of other engineering measure,the tunnel collapse construction was completed successfully. |
