兰州炼油厂曾于1956年和1957年用卷装法试制了300米~3、2000米~3、以及5000米~3立式焊接油罐。现将试制和安装经过简单介绍如下。一、准备工作根据预制场距离安裝油罐的现场很近,以及我们准备进行卷装的大型油罐数量不多的特点,我们采取了只对罐体进行卷制与桁架分片吊装的施工方案,对罐底和罐顶则仍采用一般正装的施工方法。为了克服运输工具上的困难,分别选择了两个距油罐基础不超过200米的预制场地。用滚杠运输卷筒。壁板预制平台是在平好的地面上铺上Π14型钢,互相间距离约500
Lanzhou Refinery had in 1956 and 1957 with the package method of trial production of 300 m ~ 3,2000 m ~ 3, and 5,000 m ~ 3 vertical welding tank. Trial and installation will now be a brief introduction is as follows. First, the preparatory work According to the prefabricated yard from the installation of tanks close to the scene, and we are prepared to carry a small number of large-scale capacity of the package, we have taken only the tank roll and truss pieces of construction plans hoisting , The tank bottom and tank top are still using the normal formal method of construction. In order to overcome the difficulties in the means of transport, two prefabricated sites, each not exceeding 200 meters from the base of the tank, were selected. Roll the drum with rollers. Siding prefabricated platform is laid on the ground level Π14 steel, the distance between each other about 500
