항주오대교침관수도시세계범위내최장、매치최심、규모최대적해저공로침관수도，수도결구위반강성절단식침관，설계사용수명120 a，관절지수공제시학보항주오대교예제침관사용수명적관건기술，기중주장관안장여주장시관절지수적최주요조시。문장대주장관안장화주장공예등진행상세천술。목전지수효과량호。
Hongkong-Zhuhai-Macao Bridge immersed tunnel is the longest, the deepest buried, and the largest-scale highway immersed tunnel under the sea in the worldwide, for the semi-rigid sectional immersed tube tunnel structure, the service life of the design is 120 a, immersed sealing control is the key technology to ensure the service life of the Hongkong-Zhuhai-Macao Bridge prefabrication immersed tubes, including grouting pipe installation and grouting pipe joint are the main measures of water sealing. This paper focused on grouting pipe installation and grouting process. The water sealing effect is good at present.
