BIM技术在地铁机电工程中的应用效果研究

Study on the Application Effect of BIM Technology in Metro Mechanical and Electrical Engineering

机电工程是地铁建设中的重点内容,其所涉及到的站点较多、路线较长、管线布置比较复杂,这样在一定程度上也增加了工程量,延长了工期。地铁机电工程主要包括通风空调的安装、给排水及消防设施的安装、动力照明、信号系统、通信系统以及BAS、FAS、PSD等。传统的机电工程在进行安装时所使用的图纸为二维图纸,其中存在的这大量的错漏碰缺情况,尤其是通风、水电及弱电等专业间管线碰撞情况比较严重,加大了机电工程项目的管理压力,因此,在现阶段的地铁机电安装过程中利用BIM技术对管线进行布置,并对构件的预制进行指导,实现现场安装,在此基础上提升机电安装的质量及管理水平。

Mechanical and electrical engineering is the key content in subway construction, which involves many stations, long routes and complex pipeline layout, which also increases the project quantity and prolongs the construction period to a certain extent. Subway mechanical and electrical engineering mainly includes the installation of ventilation and air conditioning, water supply and drainage and fire protection facilities, power lighting, signal system, communication system and BAS,FAS,PSD. The drawings used in the installation of traditional mechanical and electrical engineering are two-dimensional drawings, in which a large number of errors and leakage collision exist, especially the serious collision between professional pipelines such as ventilation, hydropower and weak electricity, which increases the mechanical and electrical machinery and electrician. The project management pressure, therefore, during the current subway electromechanical installation process, the BIM technology is used to arrange the pipeline, and the prefabrication of components is guided to realize the field installation, on this basis, the quality and management level of the electromechanical installation is improved.
