基于城市中心区域下沉式电缆综合工作井设计方案研究

Research on the Design Scheme of Sunken Cable integrated Working Well Under the City Center Area

传统电缆综合工作井以高于地面的形式存在,在通风、排水等方面具有一定优势,但存在与城市规划不协调的矛盾。针对城市中心区域规划要求的提高,将电缆综合工作井设计分为3大模块、8个设计要素,利用多个通风腔体相连转换,改变通风路径,设置双层通风口,从而提出下沉式电缆综合工作井设计方案。利用ANSYS有限元软件对设计方案进行了建模验证,实体模型与试点工程的应用运行数据表明,该城市中心区域下沉式电缆综合工作井在不露出地面的情况下满足通风排水功能,解决了电力设施突出地面与城市规划之间的矛盾,美化了城市形象,具有良好的社会效益和推广应用价值。

The traditional cable comprehensive working well is higher than the ground,which has certain advantages in ventilation and drainage,but it is not in harmony with urban planning.In view of the improvement of urban center area planning requirements,the design of cable comprehensive working well is divided into three modules and eight design ele-ments.By using mul tiple ventilation cavities connected and converted,the ventilation path is changed and double layer vents are set,so that the design scheme of sunken cable comprehensive working well is proposed.The design is modeled and verified using ANSYS finite element software.The application operation data of the solid model and the pilot project show that the sunken cable comprehensive working well in the central area of the city meets the ventilation and drainage function without exposing the ground,which solves the contradiction between the prominent ground and urban planning of power facilities,beautifies the city image,and has good social benefits and promotion and applica tion value.
