Imisebenzi yokukhupha iqhuba ngokupheleleyo kwiSiqithi saseBald Head, njengoko iikontraka zihambisa isanti ukusuka e-Jaybird Shoals elunxwemeni ukukhusela i-rock groin kunye nokongeza imathiriyeli eSouth Beach.

I-Marinex Construction Co. dredge iqale ukutsala isanti malunga neeveki ezintathu ezidlulileyo kwaye malunga nesinye kwisithathu siwenzile umsebenzi, amagosa aqikelela.Asebenza ngexesha lasebusika ukuze aphephe ukuphazamisa ufudo lwaselwandle oluzalela iindlwane kunye neentlobo zeentlanzi ezifudukayo.

UDale McPherson, obeke iliso kwindawo yenjineli u-Erik Olsen, uthe i-24-intshi dredge yayihambisa umndilili we-10,000 yee-cubic yadi zesanti ngosuku, kodwa inosuku olunye xa yatsala ii-cubic yadi ezingama-30,000.Ikhontrakthi yeDolophana yeedola ezili-11.7-million ifuna kubekwe i-1.1-million cubic yards of sand.

Umsebenzi wenza izinto ezininzi.Okokuqala, ibeka isanti ngasemva kunye nenxalenye ye-terminal rock groin apho amalwandle aseNtshona naseMzantsi adibana khona.Oko kubekwa kubizwa ngokuba yi-fillet.Umsebenzi uya kubonelela ngesanti elunxwemeni kwaye uvale iityhubhu ze-geotextile ezili-13 ezizaliswe yisanti ezinceda ukugcina i-South Beach ingatyibiliki kwijelo lokuthumela elikufutshane.

I-rock groin - ekuphela kohlobo lwayo kurhulumente - isebenzisa amatye amakhulu acwangciswe njengengalo egobileyo ukubambisa abanye, kodwa hayi yonke, intlabathi efudukayo yonxweme olude.

Lilonke, ukukhutshwa kuya kudala i-berm ephakathi kwama-200 kunye nama-250-eenyawo ububanzi eyolula malunga nesiqingatha semayile, utshilo uJeff Griffin, umncedisi womphathi welali kunye nokhuseleko lonxweme.

UMcPherson uthe abaqhubi bebezisa intlabathi ekumgangatho ophezulu elunxwemeni kwaye abakhange bafumane naziphi na iingxaki ezibalulekileyo.Bayibethe imfumba yamalahle alukhuni ababengayilindelanga ngenye imini kodwa bakhawuleza bawubeka ngokutsha udoti ukunqanda amalahle.Abasebenzi abaselunxwemeni basusa onke amanqindi alingana namanqindi ngoko nangoko.Amagosa asezilalini akholelwa ukuba eli lahle kusenokwenzeka ukuba lawa kudala ukusuka kwenye yeenqanawa ezininzi ezazifudula zityhutyha iLower Cape.

Umbhobho we-dredge uquka isixhobo sokuqhekeza esivumela abasebenzi ukuba babeke isanti ecaleni kwamacandelo ahlukeneyo onxweme ngaphandle kokubeka ngokupheleleyo umbhobho.

Isinyathelo esilandelayo siya kuba yiBradley Industrial Textiles ukuba ithathe indawo ye-groin tubes egcwele isanti, utshilo uGriffin.Iityhubhu ezitshintshwayo ziya kuba ne-coating ukuze zikwazi ukumelana nokukhanya kwe-ultraviolet xa zingagqunywanga ngokupheleleyo yisanti, utshilo.Loo khontrakthi yeye-1.04 yezigidi zeedola.

Ngexesha lokwakha, abahamba ngeelwandle bayacelwa ukuba baphephe iindawo ezibiyelwe ngokupheleleyo kwaye basebenzise kuphela iindawo ezinqamlezileyo ezigqunywe yintlabathi xa benyathela phezu kombhobho wedredge.
