盾构隧道管线捷装技术的应用和发展
|
摘要
盾构隧道内传统管线安装技术存在诸多质量和安全隐患,严重影响地下盾构隧道的施工建设和安全使用,为了解决以上难题,提出可在盾构隧道的机电设备和管线安装中采用管线捷装技术。管线捷装技术是指将带齿槽道安装在盾构管片上,形成一个稳定可靠的安装平台,机电设备和管线可以通过配套的支吊架安装在这个平台上。其中,预埋槽道技术指带齿槽道可先期预制进盾构管片中,外置槽道技术指可后期安装到盾构管片上。管线捷装技术利用了标准化齿槽便于调节的灵活性和牢固的齿间啮合作用,是对盾构隧道技术深入认知和探索后的技术创新和突破;此外,管线捷装技术还具备安全环保、经济快捷等优势。管线捷装技术将是未来盾构隧道内设备及管线安装的发展方向。
The traditional pipeline installation technology in shield tunnel is always with quality and safety risk,which would seriously affect the construction and safe operation of shield tunnel. Hence,the rapid installation technology for pipeline is proposed for the installation of electromechanical equipment and pipelines in the shield tunnel. The cogging channel is installed on shield segment,and a stable and feasible installation platform is established,through which the electromechanical equipment and pipelines can be installed by supporting suspension frame. The tooth groove can be preburied in the shield segment,and can also be set on shield segment. The pipeline rapid installation technology makes use of the flexibility of standard tooth groove for adjustment and the strong interaction between teeth,which is a technical innovation and breakthrough of shield tunneling technology. Meanwhile,the rapid installation technology of shield tunnel pipeline has the advantages of safety,environmental protection and economic efficiency,which is the developing direction of installation of equipment and pipelines in shield tunnel in the future.
