摘要

为解决大跨度装配式地铁车站施工过程中预制构件自身质量大和形状特殊等因素对其拼装精度和快速定位影响大的问题，依托长春地铁2号线西兴站，首先分析大跨度地铁车站拼装工程技术重难点问题，然后叙述改进后的定位拼装平台的功能，最后从拼装方法、拼装步序、定位过程控制、纠偏控制、基础平面处理和榫槽注浆方面详细阐述拼装施工技术，并运用于工程实践。得出主要结论如下： 1）在现场运用改进后的液压三维定位拼装平台，提高了拼装平台组成构件的拼装精度； 2）开发的装配式预制构件拼装技术，实现了高效、快速、准确的拼装； 3）建立的装配式预制构件连接与拼装的定位技术及纠偏控制，解决了定位精确度及效率不高的难题。

Abstract

When constructing largespan prefabricated metro stations, the characteristics of precast components, such as their large weight and special shape, often affect their assembling accuracies and rapid positioning. Based on this fact, a case study is conducted on the Xixing station of the Changchun metro line 2, China. First, the prefabricated construction difficulties of the largespan underground station are investigated. Then, the requirements of the improved positioning assembly platform are described, after which the prefabricated construction technology is introduced in detail. Remarkably, this technology comprises the assembly method, assembly sequences, positioning process control, deviation correction control, foundation plane treatment technology, and mortise/groove grouting technology. Hence, the following conclusions are drawn from investigations: (1) The improved hydraulic 3D positioning assembly platform improves the assembly accuracy of an assembly

platform′s components. (2) Efficient, rapid, and accurate assembly is achieved using the developed prefabricated component assembly technology. (3) Accurate and efficient assembly of prefabricated components is realized by the established positioning and deviation correction control technologies.
