求翻译：本次工程中采用双门双墙结构，内层为消声结构，外层为隔声层。用2.2mm钢板制成龙骨架，最外层使用2.0mm冷轧钢板折型机上成型后封在龙骨架上，内部填充隔音绵，在内层用1.2mm镀锌钢板封在表面，这样就形成一堵可移动的隔音墙。根据需要施工工程图分成若干块生产，完成后运到现场拼装。生产及拼装的接缝处我们进行密封门处理以防止其漏声。根据室内环境的要求我们处理方式有所不同最终达到用户实验室的要求。是什么意思？

This works in the two-door double-wall structure, muffler structure for an internal layer, outer layer for sound insulation layer. Made with 2.2mm steel joist, outermost 2.0mm cold rolled steel sheet folding machine molding on the keel, interior noise insulation sponge, in inner 1.2mm for galvanized surfaces, thus forming a wall of noise that can be moved. Production of construction works into several blocks as needed, assembling complete games to the scene. Production and assembling at the seams, we sealed the door to prevent leakage. According to the requirements of the indoor environment we handle differently eventually meet the requirement of user laboratories.
