人工挖孔桩预制拼装钢筋混凝土护壁施工技术 摘 要:由于人工挖孔桩是地下作业,其安全防护措施显得尤其重要,工程中时常发生人工挖孔桩成孔过程中由于桩孔护壁的破坏或倒塌, 造成人身安全事故
在底层不良的情况下确保作业人员的安全,必须对护壁措施进行改良
采纳钢筋混凝土预制拼装护壁能够快速的维护不良土层的稳定,同时将护壁混凝土等强时间压缩,加快了施工速度

In the construction market, due to the destruction or collapse of the pile hole protection wall, personal safety accidents occur in the process of the artificial digging pile hole formation in the engineering market
In order to ensure the safety of the operators, the wall protection measures must be improved
Adopting reinforced concrete precast assembled retaining wall can quickly maintain the stability of the bad soil
