石油部第四工程公司施工的天津石油化纤厂通风、保温工程量很大,达20多万米~2(其中铝皮6万米~2、铁皮14万米~2),而且质量要求高,工艺、结构复杂情况是以往少见的。他们经过反复实践,吸收国外先进经验,抓了施工工艺改进及加深机械化予制两个环节,并推广了空间立体图交底新方法,变被动为主动,加快了工程建设速度。在保温施工工艺方面有以下改进:1.改弯头下料正开口的习惯做法为旁开口连接。仅此一项可节省工时20％、省料10％。
Tianjin Petrochemical Fiber Plant, which is constructed by the Fourth Engineering Company of Ministry of Petroleum, has a large amount of ventilation and insulation works of over 200,000m2 (including aluminum skin of 60,000m2 and metal skin of 140,000m2) and high quality requirements. Process, complex structure is rare in the past. After repeated practice, they absorbed two advanced experiences from abroad, grasping the improvement of construction technology and deepening the mechanization and prerequisites. They also promoted the new method of spatial three-dimensional map, changing from passive to active and speeding up construction. In the insulation construction process has the following improvements: 1. Change the elbow is expected to open the next practice for the side openings to connect. This alone can save 20% of working hours, saving 10%.
