The invention discloses a butt joint structure for large-diameter pipeline site construction. The butt joint structure comprises a first pipeline and a second pipeline, wherein a plurality of lifting devices with universal wheels are detachably arranged at the bottoms of the first pipeline and the second pipeline, and the first pipeline and the second pipeline are coaxially and oppositely arranged; the opposite-pulling assembly comprises a first connecting piece which is detachably arranged in the first pipeline, a plurality of fixing pipes parallel to the axis of the first pipeline are arranged on the first connecting piece, first butt joint pipes coaxial with the fixing pipes are detachably arranged in the fixing pipes, and a telescopic rod coaxial with the first pipeline is detachably arranged on the first connecting piece; the second connecting piece is detachably arranged in the second pipeline, a plurality of second butt joint pipes parallel to the axis of the second pipeline are arranged on the second connecting piece, first butt joint pipes corresponding to the second butt joint pipes are movably inserted into the second butt joint pipes, a main connecting block is arranged on the second connecting piece, and the telescopic end of the telescopic rod is detachably connected with the main connecting block. The difficulty of direct alignment and butt joint of the first pipeline and the second pipeline can be effectively reduced, and a butt joint opening is tight and neat.
本发明公开了一种大直径管道现场施工对接结构,包括:底部均可拆卸设有多个带有万向轮的升降装置的且同轴对口设置的第一管道、第二管道;对拉组件,其包括:第一连接件,其可拆卸设在第一管道内,第一连接件上设有多个与第一管道轴线平行的固定管,固定管内可拆卸设有与其同轴的第一对接管,第一连接件上可拆卸设有与第一管道同轴的伸缩杆;第二连接件,其可拆卸设在第二管道内,第二连接件上设有多个与第二管道轴线平行的第二对接管,第二对接管内移动插设有与其对应的第一对接管,第二连接件上设有主连接块,伸缩杆的伸缩端与主连接块可拆卸连接。本发明能有效降低第一管道和第二管道直接对齐对接的难度,且对接口严密整齐。
