ʻO ka pahū liʻiliʻi liʻiliʻi i waho me ka ikaika
I kēia mau lā, ʻo ka mea kākau ma ka Caoe River Estuary Shangyu "ʻeiwa ʻeono mau puʻu" hoʻoponopono a me ka reclamation papahana kahua, ke hoʻohana nei nā limahana i kahi slurry pump liʻiliʻi no ke kūkulu ʻana i ka pā. He pūʻulu lākou ʻekolu ʻelima mau kānaka, ma o ke kiʻekiʻe puʻupuʻu squirt pū lepo, slurry pump suction a me ka hāʻawi ʻana, hana ʻia e ke kanaka ʻo Cheng sludge, nā kaʻina hana maoli o ka bakeke wai, piecewise hierarchical elevation o ka levee.
slurry pump ma ka South Bank o Qiantang River embankment a puni ka noi o ka aneane ʻumi makahiki o ka mōʻaukala. ʻO ka hoʻohana ʻana i ka pauma slurry i kēlā me kēia lā earthwork i hoʻopau ʻia 300 a 500 cubic mika, ke hoʻohālikelike ʻia me ka hana ʻana i ka lepo manual e hoʻomaikaʻi i ka hana maikaʻi 30 mau manawa, ʻoiai ke kumu kūʻai o ka earthwork he 1/5 wale nō ka pae honua kūlohelohe, a me ka compactness kiʻekiʻe, maikaʻi maikaʻi. Mai Xiaoshan, Shaoxing, Shangyu a me nā kalana ʻē aʻe i ka makahiki 1989 i hoʻomaka i kahi noi nui o ka slurry pump embankment kūkulu ʻia, ʻo ia ka ʻāina reclamation 90000 mu, e mālama ana i ke kumukūʻai o 40000000 yuan.
