Abstract

The invention relates to a pipe joint butt joint and guide device, in particular to a butt joint and guide device applied to pipe joint butt joint operation in immersed pipe tunnel construction. The device comprises a guide frame and a guide rod, wherein the guide frame is connected with an installed pipe joint, the guide rod is connected with a pipe joint to be installed, a guide groove is formed in the guide frame, and the guide groove is used for containing the guide rod. By the design of the guide rod and the guide frame, the guide rod can be placed into the guide groove, and the two pipe joints are made to basically align with each other, namely the axes of the two pipe joints basically coincide with each other; the butt joint end of the pipe joint to be installed finally aligns with and draws close to the tail end of the installed pipe joint; by the adoption of the structure, butt joint is more quickly and smoothly conducted; the construction progress is shortened, and butt joint accuracy is improved; work faults are reduced, and major accidents are avoided.

Description

technical field [0001] The invention relates to a butt joint guide device for pipe joints, in particular to a butt joint guide device applied to the joint joint operation of pipe joints in the construction of immersed tunnels. Background technique [0002] In the current subsea tunnel project, the underwater docking operation of pipe saving is a very important part, and it is also the difficulty of the entire subsea tunnel project; due to the influence of the underwater environment, the underwater operation has many uncertainties, and its construction is also quite difficult. In particular, it is necessary for the staff to complete the docking operation in diving; therefore, the construction progress is slow due to docking errors, and the long underwater operation time not only greatly increases the construction cost but also poses a threat to the personal safety of the staff; how is it for the construction party? It is an urgent problem to be solved to quickly and accuratel...
