| ①、图纸已经熟悉，并且经过图纸会审。对建筑、结构和电气、暖卫施工图中的管路走向、坐标、标高与通风管道之间跨越交叉在图纸上出现的问题已经有解决方案。 The drawings have been familiar with and have been examined through drawings. Solutions have been proposed to solve the problems of crossing and crossing between pipeline orientation, coordinates, elevation and ventilation ducts in the construction drawings of buildings, structures and electrical and heating and sanitation works. ②、材料表面油污应全部清除干净，以免铁锈或氧化物落于材料表面产生局部腐蚀。 (2) Oil stains on the surface of the material should be completely removed to avoid local corrosion caused by rust or oxides falling on the surface of the material. ③、必须有一个单独的加工场地，为了不破坏镀锌钢板外的保护膜，工作场地最好铺设木板或者橡胶板，保持场地清洁。 (3) There must be a separate processing site. In order not to destroy the protective film outside the galvanized steel sheet, it is better to lay wood or rubber boards on the working site to keep the site clean. ④、已进行了施工技术交底，对风管制作的尺寸，采用的技术标准、接口及法兰连接方法已经明确。并且已经做好施工交底记录。 (4) The construction technology has been reported, and the technical standards, interfaces and flange connection methods for the dimensions of air ducts have been defined. And the construction record has been completed. |
