The invention discloses an integral or sectional construction method of a high-leakproofness air pipe in a narrow well, the leakproofness test shows that the air leakage amount of the whole air pipe installed by the construction method is only 7% of that of a traditional mode, the one-time acceptance success rate of a smoke exhaust system is greatly improved and can be improved to 95% from 78%, and the construction efficiency is greatly improved. And meanwhile, the number of bolts which cannot be fastened in the super high-rise tube well is reduced to about 2% from traditional 15%. Due to the fact that operation is convenient and fast, labor cost is reduced by about 20%, manufacturing cost is reduced by 15%, material loss is reduced by about 30%, and safety of well operation is effectively improved.

    本发明公开了一种狭小井道内高严密性风管的整体或分段式施工方法,本发明的施工方法安装的风管整体,经过严密性测试,漏风量仅为传统方式的7%,大大提升了排烟系统的验收一次成功率,可以由78%提升至95%,同时实现了在超高层管井中将无法紧固的螺栓数量从传统的15%降低至2%左右。也因为操作便捷,缩小了人力成本20%左右,减少了15%的造价和减少了30%左右的材料损耗,并有效提高了井道作业的安全性。
