技术领域technical field

本发明属于地下工程建造技术领域,具体涉及一种装配整体式拱顶大跨无柱地下结构。The invention belongs to the technical field of underground engineering construction, and in particular relates to an assembled integral vault large-span column-free underground structure.

背景技术Background technique

目前地下结构采用的是传统的现浇钢筋混凝土结构施工技术,设计过程复杂,工作量大。现场施工过程中需要大量的多工种的劳动力,施工作业环境差,施工工序复杂,施工速度慢,施工质量难以保证。施工过程中产生很多废弃的建筑垃圾,既浪费资源又污染环境。现浇混凝土结构施工管控参差不齐,完成施工后往往因各方面原因导致混凝土结构外观或者内在经常出现各种质量缺陷,后期修复难度大,质量难以保证。At present, the underground structure adopts the traditional cast-in-place reinforced concrete structure construction technology, the design process is complicated and the workload is heavy. The on-site construction process requires a large number of multi-skilled labor, the construction environment is poor, the construction process is complicated, the construction speed is slow, and the construction quality is difficult to guarantee. During the construction process, a lot of abandoned construction waste is generated, which wastes resources and pollutes the environment. The construction control of cast-in-place concrete structures is uneven. After the completion of the construction, there are often various quality defects in the appearance or interior of the concrete structure due to various reasons. It is difficult to repair later and the quality is difficult to guarantee.

随着科技的进步、装备制造业的发展、产业升级转型,越来越多的工作由机器替代人力,高技术代替劳动密集型、自动控制装备代替人工控制。在建筑工程领域所需要的各种构件(梁、板、柱、墙)将会逐渐在工厂批量化生产,然后运输到现场进行拼装完成。With the advancement of science and technology, the development of the equipment manufacturing industry, and industrial upgrading and transformation, more and more jobs are replaced by machines, labor-intensive by high technology, and manual control by automatic control equipment. Various components (beams, slabs, columns, walls) required in the field of construction engineering will gradually be mass-produced in factories, and then transported to the site for assembly.

随着装配式技术的发展,地下结构也陆续出现了部分装配式设计、施工技术方案;有些仅适用于地下水少且采用放坡或者锚索(杆)开敞式明挖基坑,不适用于地下水丰富的地区;有些仅仅局部采用装配式结构,装配程度不高,装配效率低;而常规有柱地下结构,地下空间视野不开阔;有些仅适用于明挖基坑体系。With the development of prefabricated technology, some prefabricated designs and construction technology schemes have gradually emerged for underground structures; Areas with rich groundwater; some only partially adopt prefabricated structures, the degree of assembly is not high, and the assembly efficiency is low; while conventional underground structures with columns, the view of underground space is not wide; some are only suitable for open-cut foundation pit systems.
