各型式预制综合管廊的特点与关注问题探讨

Technical Characteristics and Related Discussion of Different Precast Utility Tunnel Types

摘要: 搜集列举了当今主要的预制综合管廊的型式与各自技术特点，并针对关注问题进行相关介绍与探讨。通过对当前国内工程实例与厂家资料的收集，对预制综合管廊的主要型式——预制拼装式与预制叠合装配式进行相关介绍，并针对重点关注的防水、运输吊装等事项进行进一步的阐述。相关资料表明，虽然现有工程实例中，现浇结构仍占绝大多数，但预制综合管廊凭借其自身特有的优势与潜力，可在今后的工程应用中有更广阔的前景。

Abstract: Different types of precast tunnel and their characteristics are collected, and the related discussion is made in this thesis. Through the collection of engineering examples and manufacture information, we give the related introduction about the main types of precast tunnel: assembled precast municipal tunnel and composite precast tunnel. Meanwhile, waterproof, transport and hoisting are especially focused on as the main problems. The relevant data show that although the cast-in-place structure still account for the vast majority of the existing engineering, precast tunnel with its own unique advantages and potential has a wide prospect in engineering application
