| Abstract: | The project of optical cable tube crossing at Qiantangjiang River with the length of 2 454.15 m and the depth of about 32 m has adopted many new techniques, new processes and new methods, which upgrade the crossing technology to a brand-new level. The applications of the techniques in this project including guided borings from both sides, casing technique, technique of cable laying by means of underwater magnetic field, technique of long distance mud circumfluence and technique of drilling pipes assembled for long distance drilling operation are described. |
