用模型指导施工,直观易懂,在国外早已推广应用。在天津石油化纤厂的 PX 装置室内电缆安装施工中,石油部第四工程公司电仪队,采用了电缆安装模型指导施工。该装置共有784根电缆从室内配出,计138KM,结构型式复杂,安装尺寸严格。外商仅提供了两张图纸,剖视、剖面很多,很难建立起完整的概念。采用模型化施工,能正确地表达电缆支架的位置及托盘的走向,形象地反映出各部的结构形式,使每个施工人员能建立起较完整的空
Guided by the model construction, intuitive and easy to understand, has long been promoted in foreign applications. In Tianjin Petrochemical Fiber Plant PX installation of indoor cable construction, the Ministry of Petroleum Engineering Company IV electrical instrument team, using the cable installation model to guide the construction. The device has a total of 784 cables dispensed from the room, total 138KM, complex structure, installation size strict. Foreign businessmen only provided two drawings, cutaway view, many profiles, it is difficult to establish a complete concept. With the model construction, the position of the cable supporter and the direction of the tray can be correctly expressed, and the structure of each department is vividly reflected so that each construction worker can establish a relatively complete space
