【摘要】：铁路桥梁是铁路建筑工程的重要组成部分之一,而铁路桥梁中大部分为预制梁。本文将以铁路预制桥梁施工质量管理进行分析和研究。因铁路预制桥梁工程的结构类型复杂、质量要求高、体型庞大、施工周期长、受地理条件约束大、受天气影响大等一系列特性,使得铁路预制桥梁施工质量管理比一般工业产品生产质量管理更难控制。本文以笔者亲历的一项实际工程为案例—新建QZCZQ-6标正线(DK152+335~DK167+925)15.59公里范围内9座桥梁的预制简支T梁工程,针对预制桥梁施工阶段的质量管理进行分析和研究。根据实际工程情况,主要从施工质量控制的重点(施工过程质量控制和特殊季节质量控制)、难点(质量管理信息化和质量风险管理)等进行分析和研究,针对各种质量要求和问题,提出了一系列质量保证措施,形成了一套比较完整的预制桥梁工程项目施工质量管理方法。在项目实施过程中对预制桥梁质量问题有明显的改善,初步取得良好的效果。
[Abstract]:Railway bridge is one of the important components of railway construction, and most of railway bridges are prefabricated beams. In this paper, the construction quality management of railway prefabricated bridges will be analyzed and studied. Because of the complex structure type, high quality requirement, large size, long construction period, large constraints of geographical conditions and great influence of weather, the railway prefabricated bridge project has a series of characteristics, such as: the structure type is complex, the quality requirement is high, the construction period is long, The construction quality management of railway prefabricated bridges is more difficult to control than the general industrial production quality management. This paper takes a practical project experienced by the author as an example-the prefabricated simply supported T-beam project of 9 bridges within 15.59 km of newly built QZCZQ-6 standard main line (DK152 335 / DK167 925). The quality management of prefabricated bridge construction phase is analyzed and studied. According to the actual engineering situation, the key points of construction quality control (construction process quality control and special season quality control), the difficult points (quality management information and quality risk management) are analyzed and studied. Aiming at various quality requirements and problems, this paper puts forward a series of quality assurance measures and forms a set of relatively complete construction quality management methods for prefabricated bridge projects. In the process of implementing the project, the quality of prefabricated bridges has been improved obviously, and good results have been obtained.
