Abstract
Construction of the abutment, pier, and pier cap of long cross-sea bridges are challenging in complex marine environments. In the Hong Kong-Zhuhai-Macao Bridge (HZMB) project, an installation process characterized by concrete integral prefabricated abutment and pier (IPAP) with a flexible water stop curtain was invented. Studies showed that the underwater connection of IPAP and foundation piles can be achieved by adopting the steel cover box (SCB) scheme and separate flexible tray water stop technology. Compression bimodal GINA water stops are valid to seal the gap between SCB and IPAP. The horizontal water stops between trays and IPAP underside are achieved by jacking and compressing GINA water stops, whereas the vertical water stops between trays and steel piles casing (SPC) within 20 m deep underwater are achieved by a rubber capsule with 0.4 MPa pressure. After achieving the water stop between reserved holes and SPC, rapidly hardening concrete is cast into reserved holes. This reliable, efficient, and ecologically friendly innovative construction process, especially the water stop method, ensures that HZMB was constructed more safely and efficiently the China White Dolphin habitat.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
