The river-dredging and sea-crossing engineering and the underwater construction engineering need to build an underwater structure and pour underwater concrete. In the process of underwater pouring concrete, in order to ensure that the concrete is not interfered by water and keep the integrity and continuity of the concrete, a guide pipe is usually adopted for auxiliary pouring. The guide pipe is processed by a seamless steel pipe with the thickness of 5-8mm, and a plurality of guide pipes with the length of 2-4m and hoppers are usually required for underwater construction. Assembling the guide pipes section by section to the designed length before concrete pouring; the pipes are removed section by section along with the pouring of the underwater concrete, the bottom of each pipe is always ensured to be buried in the concrete, and the pipes (particularly the joint positions) must be strictly sealed. In the whole underwater concrete construction process, the key is that the guide pipes are installed and removed section by section, and the construction efficiency and the concrete quality are determined.
The common connection forms of the current conduit are a spiral sleeve connection and a flange connection. The two connection modes have a large number of repeated screwing and loosening operations, are more complicated, have finer connecting threads and are easy to damage; and underwater sealing performance is not durable.
