Guide device and method for butt joint of immersed tubes
The invention relates to the technical field of tunneling construction of immersed tubes and provides a guide device and method for butt joint of immersed tubes. The guide device comprises guide bars and guide frames. The guide frames are disposed at the top tail of an immersed segment. From lengthwise view of the immersed segment, each guide frame is in a structure contracting gradually from top to bottom. The guide bars are disposed at the top front of the immersed segment. One end of every guide bar overhangs from the front end of the immersed segment; the diameter of the guide bars fits the width of the bottom of the guide frames; the axial centers of the guide bars are located on a central interface of the guide frames. The guide device and method is suitable for pre-laying immersed tube tunnels; owing to the use of the immersed tubes, a nose support is not required; by providing the guide bars at the top front of the immersed segment and the guide frames at the top tail of the immersed segment, when sinking to a foundation, a segment to be immersed automatically horizontally aligns with the immersed segment, construction efficiency is greatly improved, and labor intensity is greatly lowered.
