The present invention relates to a combined pipe kit and a raft. The combined pipe kit has a main body of a detachable group. The second half system of the main body is mated and detachably arranged on the first half of the main body. The raft body adopts the combined pipe set to be arranged at the staggered position of the pipe fittings, and the first half and the second half of the combined pipe set can be directly fitted and combined at the staggered position of the pipe fittings to improve assembly convenience and replace The first half body and the second half body can be removed in situ, without the need to pump the pipe fittings, so that the purpose of easy replacement is achieved, and the combined pipe kit provides through holes arranged vertically and axially to each other. The staggered position of the pipe fittings is vertical to improve the balance stability.本發明係一組合式管套件及一筏體,該組合式管套件具有可拆組的一本體,該本體的第二半體係對合且可拆組地設置於該本體的第一半體,該筏體採用所述組合式管套件設置於管件的交錯處,且組合式管套件的第一半體與第二半體可直接套合組合於管件的交錯處,提高組裝便利性,且更換時可原地原處將第一半體與第二半體拆下即可,且不需要抽動管件,故達到便於更換的目的,以及該組合式管套件提供相互垂直軸向配置的通孔,以定位管件交錯處呈垂直以提高平衡穩定性。
