Bottom changing construction method for cave depot oil tank
The invention relates to a bottom changing construction method for a cave depot oil tank. The method comprises the following steps: ventilating and cleaning the oil tank, forming a temporary feeding hole, installing a transportation platform in a temporary channel, jacking the oil tank, cutting the bottom of the oil tank, replacing an asphalt sand cushion layer, conveying a new sand cushion layermaterial, conveying asphalt sand, conducting centering operation on the tank bottom, carrying out typesetting processing on the tank bottom outside a cave depot, conveying a middle plate, side platesand arc-shaped plates into the oil tank through the transportation platform, welding the middle plate, the side plates and the arc-shaped plates into a whole to form a new tank bottom, and welding thenew tank bottom and the side wall of the oil tank together to complete bottom changing construction of the oil tank. According to the method, the conveying efficiency is improved, the temperature requirement of asphalt sand cushion layer construction is guaranteed, the bottom plate can be manufactured to be larger, the length of a bottom plate weld joint is greatly reduced, the construction efficiency is improved, and deformation during welding is reduced.
本发明涉及一种洞库油罐换底施工方法，包括油罐通风以及清洗、开设临时进料口、在临时通道内安装运输平台、对油罐进行顶升、对油罐罐底进行切割、更换沥青砂垫层、输送新的砂垫层材料、输送沥青砂、进行罐底对中操作、在洞库外对罐底进行排版加工、使用运输平台将中间板、侧板以及弓形板输送至油罐内，将中间板、侧板以及弓形板焊接为一体形成新罐底，并将新罐底和油罐侧壁焊接在一起，完成油罐的换底施工。本发明提高了输送效率，保证了沥青砂垫层施工的温度要求，使底板板材能够做的较大，大大缩减底板焊缝的长度，提高施工效率、较少焊接时的变形。
