摘要
本研究旨在提升地铁工程施工的质量水平,通过深入剖析地铁盾构技术的工作机理及其技术特性,结合宁波市轨道交通7号线土建工程TJ7019标段施工过程,探讨并提炼出一系列地铁盾构施工的质量与安全控制措施.本文首先详细说明了盾构机的作业原理,包括土压平衡原理及其对周边环境的保护效果,随后分析了盾构施工过程中的关键技术难点,如地质适应性、施工参数优化、管片装配精度等.通过实践验证,提出的保障措施在确保施工安全的同时,显著提高了施工质量.
Abstract
This study aims to improve the quality level of subway engineering construction,discusses and refines a series of quality and safety control measures for subway shield construction through an in-depth analysis of the working mechanism and technical characteristics of subway shield technology,combined with the construction process of Ningbo Rail Transit Line 7 civil engineering TJ7019 bid section.This paper first explains the operating principle of the shield machine in detail,including the principle of earth pressure balance and its protection effect on the surrounding environment,and then analyzes the key technical difficulties in the shield construction process,such as geological adaptability,construction parameter optimization,and segment assembly accuracy.Through practical verification,the proposed safeguard measures can significantly improve the construction quality while ensuring the safety of construction.
