【摘要】：铁路作为我国国民经济的大动脉,在我国交通运输体系中居于主导的骨干地位。随着城市经济快速的发展和人口流动性的不断提高,人们对于铁路交通运输在时间和载客量上有了越来越高的要求,高速铁路技术的完善在一定程度上满足了城市经济发展和人口流动性的问题。高速铁路是一个集各项最先进的铁路技术、运营管理方式、市场营销和资金筹措等方面的十分复杂的系统工程,它包含基础设施建设、机车车辆配置、站车运营规则及其他方面的内容。客运专线作为高铁建设的主要内容之一,出于稳定、安全运营、维护方便及旅客乘车舒适性的原则,在线路选择模式上大多以桥梁为主,为了便于现场施工和管理,一般采用现场集中预制和架设安装的方法。预制梁的质量与生产架设速度直接影响整个工程的质量与工期,因此,铁路客运专线预制粱场的规划与生产管理的好坏在整个工程施工中起着非常重要的作用。现阶段,我国对预制梁场的规划与生产管理的重视程度相对较弱,大部分现场施工人员都是根据多年的业内经验,加之定性分析,仅以满足工期为主要目标对铁路客运专线预制梁场进行规划和生产管理。因预制梁场施工具有独立性且单品种性生产,多专业工种协同配合,交叉施工,受环境条件影响大等特点,并不是聚集一些机械设备和劳动力就能把工程建起来,而是要遵循客观规律,合理的进行施工安排,做到有序、安全、经济地实现建设工程的质量、工期和成本目标。本文结合工程实践经验,通过对铁路客运专线预制梁场前期规划中的选址、布局及建设规模等影响因素进行分析比选,并以结果为基础对梁场生产中的工艺工序及场内施工管理的影响因素再分析比选,从而得出客运专线预制梁场规划和生产策划的最优化组合,以此依据对宁安铁路客运专线铜陵顺安梁场的实际施工情况进行分析评价,从而得出本文结论,为后续梁场的施工提供一定的参考,改变施工人员的管理习惯,使铁路客运专线预制梁场的施工管理水平进一步提高。
[Abstract]:As the main artery of our national economy, railway plays a leading role in the transportation system of our country. With the rapid development of urban economy and the continuous improvement of population mobility, people have higher and higher demands on the time and capacity of railway transportation. The improvement of high-speed railway technology satisfies the problems of urban economic development and population mobility to a certain extent. High-speed railway is a very complex system engineering that integrates the most advanced railway technology, operation and management mode, marketing and financing, etc. It includes infrastructure construction, locomotive and rolling stock configuration, etc. Standing car operation rules and other aspects of the content. As one of the main contents of high-speed railway construction, the passenger dedicated line is based on bridges in line selection mode, in order to facilitate construction and management on the spot, because of the principles of stability, safe operation, maintenance convenience and passenger ride comfort. The method of centralized prefabrication and erection and installation is generally adopted. The quality and production speed of prefabricated beams directly affect the quality and duration of the whole project. Therefore, the planning and production management of prefabricated beam yard in passenger dedicated railway line plays a very important role in the construction of the whole project. At the present stage, the planning and production management of the precast beam yard is paid relatively little attention in our country. Most of the construction personnel in the field are based on years of experience in the field and qualitative analysis. Planning and production management of precast beam yard of passenger dedicated railway line is carried out only in order to meet the time limit. Because the construction of precast beam yard has the characteristics of independence and single variety production, coordination of many kinds of professional work, cross construction, and being greatly affected by environmental conditions, it is not possible to build the project by gathering some mechanical equipment and labor force. Instead, we should follow the objective law, reasonable construction arrangements, order, safety, and economic realization of the quality of the construction project, time limit and cost objectives. Combined with practical engineering experience, this paper analyzes and selects the influence factors such as location, layout and construction scale of prefabricated beam yard in railway passenger dedicated line. Based on the results, the factors affecting the process and construction management in the beam yard are analyzed and compared, and the optimal combination of the prefabricated beam yard planning and production planning for passenger dedicated line is obtained. Based on the analysis and evaluation of the actual construction situation of Tongling Shun'an beam yard of Ningan railway passenger dedicated line, the conclusion of this paper is drawn, which provides a certain reference for the subsequent construction of the beam yard and changes the management habits of the construction personnel. The construction management level of precast beam yard of passenger dedicated railway line will be further improved.
