隧道盾构施工抽出式通风方法探究

Study on Exhaust Ventilation Method of Tunnel Shield Construction

由于城市市政建设和全国轨道交通的快速发展,盾构隧道具有的安全、高效、可靠的优点在地下基础工程建设中逐渐得到了广泛的应用。但是,由于地铁隧道施工属于深入地下的长大独头类型,通风效果不理想,所以需要采取必要的措施改善施工空气质量。论文根据盾构施工的环境特点,提出使用抽出式通风的方法,并验证该方案的可行性。

Due to the rapid development of urban municipal construction and national rail transit,shield tunnels have been widely used in underground infrastructure construction with the advantages of safety,efficiency and reliability.However,because the construction of metro tunnel belongs to the long single-headed type deep underground,the ventilation effect is not ideal,so it is necessary to take necessary measures to improve the construction air quality.According to the environmental characteristics of shield tunneling,this paper puts forward the method of using exhaust ventilation,and verifies the feasibility of the scheme.
