介绍北京市轨道交通房山线阎村车辆段检查坑整体道床的施工工艺和施工质量控制。在工期紧,施工条件复杂,交叉作业频繁的情况下很好地保证检查坑整体道床的施工质量。检查坑架轨主要采用滚道线运输的方式,此方法既快又安全,有效地保障了工期;阐述施工的重难点控制:检查土建与轨道的施工接口,确保上下统一;检查基础预留钢筋,确保轨道安装正确就位;检查轨道施工范围内的预留预埋,确保不漏项;铺轨基标的保护,确保基标不被破坏且需要经常校核;通过对重难点采取有效控制措施,检查坑施工取得了良好的效果。
The construction technology and construction quality control of the integral track bed of Yancun depot of Fangshan Line in Beijing Metro are introduced. In the tight construction period, the construction conditions are complex, frequent cross-operation under the circumstances to ensure a good inspection of the overall pit construction quality. Inspection pit rack rails mainly by means of raceway transport, this method is fast and safe, effectively protect the construction period; elaborate the construction of the heavy and difficult to control: check the construction of civil and rail interface to ensure uniform up and down; , To ensure that the track is installed properly in place; check the track embedded in the construction of the pre-buried to ensure that no leakage items; laying of the basic standard protection to ensure that the base standard is not damaged and need to be frequently checked; by heavy and difficult to take effective control measures, Inspection pit construction has achieved good results.
