鞍钢1780工程空压站—地下管廊逆作法施工简介——鞍钢1780工程热连轧技改工程跟踪报道之十一

Introdution of Counter-construction on Air-compressure Station and Underground Pipeline for 1780 Engine in AISC

针对四周有建筑物、铁路密集、地质条件较差、工期十分紧迫的情况，空压站－地下管廊采用逆作法施工。阐述了逆作法工艺原理、施工程序、施工技术关键及技术经济效果。

The counter\|construction is applied on the air compressure station and underground pipeline in terms of concentrated buildings and railway all around,bad geoligical conditions and pressing time limit.The process principle of the counter\|construction,the construction precedures,the keys to construction and technical and economic benefits are described.
