Ke kōkua ana ka Hōʻailona Kahi Waena o Guangzhou-Zhanjiang i hea ʻekahi kuhikuhi kai, he kuhikuhi kai o Zhanjiang Bay. Hoʻopuka ʻia e ka kuhikuhi kai o Zhanjiang Bay ma Zhanjiang Bay me ke kūlana noho ʻelua mai 9.640 km (hiki i ka 7.352 km o ke kahakai puʻu, 1.148 km o ke kahakai wāwae ʻia a me ka hale hana (no laila, 794 m i kēia panemai hemahema)), ʻekahi kuhikuhi hoʻokahi papa me ka holo ʻelua papa me ka hopena kualapū 250km/h a me 200km/h. Ke kūʻokoʻa nei ka hope loa o ke kualapū i ka hope o 31m., no laila, ka honua lepo (lepo hemahema, lepo paheʻe, lepo paheʻe) he kanakaʻole 5 iki i ka hōʻemi ʻana i 15m. No ka makahiki hope loa o ka kuhikuhi, he ʻano ʻelua mailuna ʻoi aku 2.5 km i ka hōʻemi ʻana i nā waiwai o Zhanjiang Bay, a me ka hopena ʻāina i ka hope.

ʻEkahi o nā mea hoʻokuʻu Yuru inā makeke i ka hopena kēia, he kopepeʻe kopekope puʻupuʻuʻiʻini. Ma hope o kona kopepeʻe, no laila, ka hōʻomaikaʻi, ka hōʻomaikaʻi waiwai a me ka hōʻomaikaʻi UV, hiki ke holo kona manaʻo i ka papahana nui i ka hopena -30 ° C i ka hopena 80 ° C. ʻO ia ke kōkua ʻana i ka hopena loaʻa nui a me ka hopena ma mua o ke kūlana ʻāpana. Ke koho nei i ka waeʻawaʻe nui hoʻopau wai a me ka hopena pololei no ka hoʻokumu ʻana i nā kūlana ʻāpana a me nā hopena kahua hoʻomehana, a me ka holoʻokoʻa no nā kumuwaiwai pūnana. Ma hope oiai, ʻoiai ua hoʻomehana ʻia ka poʻe hana me ka mahina Yuru polyurethane grouting materials. He kanaka wai ka hopena polyurethane grouting, hoʻomehana ʻia no ka hōʻemi wai mai loko o nā huinahā a me nā waeʻawaʻe konikoni. ʻO ia ke kōkua ʻana i ka hopena loaʻa nui a paʻa ke kōkua i nā waeʻawaʻe konikoni. He kanaka wai ka hopena polyurethane grouting, he nui ka hopena holo, hoʻomehana ʻia no ka hōʻemi wai a me ka hoʻomaʻemaʻe i nā waeʻawaʻe a me nā huinahā konikoni ma o kēia mau kumuwaiwai. Hoʻopau wai a me ka hōʻemi wai kēia no ka hōʻemi wai hoʻomehana.
