Construction method for hoisting air pipe in vertical shaft
The invention discloses a construction method for hoisting an air pipe in a vertical shaft, which comprises the following steps: S1, preparing for construction, and enabling at least one wall body of the vertical shaft to be in an unconstructed or dismantled state; s2, a hoisting structure is additionally arranged at the top of the ventilation shaft; s3, a construction platform is erected in each layer of shaft ground reserved hole; s4, the hoisting device is assembled; s5, the air pipes and the hoisting device are assembled, the hoisting device is used for hoisting the multiple sections of air pipes in place, specifically, the first section of air pipe and the hoisting device are assembled, and after the first section of air pipe is lifted to be higher than the second section of air pipe and lower than the bottom of the top plate reserved hole in the bottommost layer of the vertical shaft, lifting is stopped; and after the second section of air pipe and the first section of air pipe are firmly connected through a flange, the whole air pipe is lifted for the second time, and the third section to the last section of air pipe are sequentially hoisted in place until the whole section of air pipe is hoisted.
本发明公开了一种竖井内风管吊装施工方法，包括如下步骤：S1、施工准备，并使竖井至少有一面墙体为未施工或拆除状态；S2、在通风竖井顶部增设起吊结构；S3、在每层竖井地面预留洞搭设施工平台；S4、组装吊装装置；S5、将风管与吊装装置进行组装，利用吊装装置进行多段风管的吊装就位：将首段风管与吊装装置组装，并将首段风管提升到高于第二段风管的高度，且低于竖井最底层顶板预留洞底部后，停止提升，将第二段风管与首段风管通过法兰连接牢固后，再整体进行第二次提升，依次完成第三段至最后一段风管吊装就位，直至完成整段风管吊装。
