ʻO nā pā kai i kūkulu ʻia ma kahakai, he mau hale hydraulic koʻikoʻi ia e kū ai i nā nalu, nā au a i ʻole nā nalu no ka pale ʻana i kahakai.Hoʻihoʻi a hoʻopaʻa ka Breakwaters i nā kahakai ma o ka hoʻopau ʻana i ka ikehu nalu, a ʻae i ke one e hōʻiliʻili ma kahakai.
Hoʻohālikelike ʻia me ka hoʻopiha pōhaku tranditonal, nā paipu geotextile polypropylene lōʻihi me nā kumukūʻai hoʻopiha piha ma ka pūnaewele ma ka hōʻemi ʻana i nā mea waho a me ka lawe ʻana.

Papahana： ʻO Chongqing Chansheng River Dredging
Lcation： Chongqing, Kina
Aia ka muliwai changsheng ma ka moku ʻo Chongqing, me kahi kīʻaha he 83.4km2 a me ka lōʻihi o ka muliwai he 25.2km.Ua hoʻohaumia nui ʻia ka muliwai no ka manawa lōʻihi, me nā pilikia e like me ka eutrophication o nā kino wai, ka pōʻino o nā paipu wai, lawa ʻole nā kumu wai a me ka luku ʻana i nā embankments, etc. hiki ke hoomalu i ka waikahe.I ka makahiki 2018, ua hoʻoholo ke aupuni kūloko e hoʻohana i nā paipu geotextile e huki i ka muliwai.
Ua hoʻomaka ka papahana ma ʻOkakopa 2018 a hiki i Dekemaba 2018. ʻO ka nui o ka lepo i mālama ʻia ma ka kahawai ma kahi o 15,000 cubic mika (90% wai maʻamau).ʻO Honghuan geotube i hoʻohana ʻia ma ka papahana he 6.85 mika ka laulā a me 30 mau mika ka lōʻihi.
Ma ke ʻano he ʻenehana e hoʻomaʻamaʻa i ke kaʻina o ka hoʻoheheʻe ʻana i ka lepo, ua hoʻolaha ʻia ka ʻōnaehana hoʻoheheʻe wai o geotube.
ʻO ka mua, mālama ʻia ka ʻōpala me ka flocculant a laila hoʻopiha ʻia i loko o ka geotube.E noho ka lepo i waiho ʻia i loko o ka paipu a e kahe ka wai mai nā pores o ka paipu.Hoʻopau hou ʻia kēia kaʻina a hiki i ka pae geotextile i ke kiʻekiʻe kiʻekiʻe.
