摘要
针对顶管施工是市政工程中常用的施工工艺,结合自身工程经验,给出了顶管施工工艺,提出了顶管施工的关键技术为:纠偏、中继环设置、减小摩阻力、管内通风、地面沉降控制,并分析了关键技术机理,为顶管施工及设计积累了经验。
The paper puts out top tube construction craft aiming at top tube construction cratf in the municipal engineering, joining together the oneself engineering experience, puts forward key method： rectify decline, repeating installation, the resistance of friction, tube ventilate and the ground decline control, and analyzes the key technique mechanism, backlogs construction and design experience for top tube.
