Matanda esimbi, sezvinhu zvinotsigirwa pakuvaka, anoita basa guru. Kune mhando dzakasiyana-siyana, kunyanyaMurwi wepepa remhando yeU, Z Type Steel Sheet Pile, mhando yakatwasuka uye mhando yekubatanidza. Mhando dzakasiyana dzakakodzera mamiriro akasiyana, uye U-type ndiyo inonyanya kushandiswa.
Chinhu chinowanzoshandiswa isimbi yakasimba uye ine simba rakawanda yeQ345B, iyo inogona kusimbisa kusimba uye kuomarara. Matanda esimbi anowanikwa muhukuru hwakasiyana-siyana, kubva pamamita mashoma kusvika pamamita anopfuura makumi maviri, ane upamhi hwakaenzana hwe600mm, 900mm, 1200mm, nezvimwewo, uye ukobvu hwakasiyana.
Murwi weMapepa eSimbiZvine hunhu hwakakosha. Kubva pamaonero ekusimba, zvakagadzirwa nesimbi yepamusoro-soro uye zvine simba guru rekukombama nekudzvanya. Zvinogona kuchengetedza kugadzikana kwechivakwa mumamiriro ezvinhu akaomarara epasi uye kumanikidzwa kwakasimba kwevhu. Semuenzaniso, mukutsigira kwakadzika kwegomba renheyo yezvivakwa zvepamusoro-soro, mirwi yesimbi inogona kutsigira ivhu rakapoteredza kudzivirira kudonha. Panyaya yekushanda kwekumisa mvura, dhizaini yekukiya yemurwi wesimbi yakanaka kwazvo. Nekurumwa kwakasimba, keteni rekudzivirira mvura rinogadzirwa kudzivirira mvura yepasi kuti isapinde munzvimbo yekuvaka. Izvi zvinonyanya kukosha pakuita kuvaka nheyo munzvimbo dzine mvura yepasi yakawanda, zvichideredza zvakanyanya mari yemvura uye matambudziko ekuvaka. Kureruka kwekuvaka zvakare chinhu chakakosha. Murwi wesimbi unogona kukurumidza kudhonzwa muvhu nerubatsiro rwemichina yehunyanzvi yekuunganidza. Kumhanya kwekuvaka kunokurumidza uye nguva yekuvaka ipfupi. Inogona kuvandudza zvakanyanya kushanda kwepurojekiti uye kuderedza kukanganisa kwekuvaka nharaunda yakapoteredza. Pamusoro pezvo, murwi wesimbi unogona kushandiswazve. Mushure mekunge chirongwa chapera, chinogona kudhonzwa uye kuiswa mumapurojekiti matsva mushure mekugadzirisa kuri nyore. Izvi zvinoderedza zvikuru mutengo wezvinhu uye zvinoenderana nepfungwa yekuvaka yegirini uye isingakuvadzi nharaunda.
Nekuda kweizvi, ine mashandisirwo akasiyana-siyana. Mukutsigira gomba renheyo yekuvaka, inoita kuti kuvaka kuve kwakachengeteka; mukuvaka madoko nemadhoki, inoshandiswa kutsigira mahombekombe; yakakodzerawo kumapurojekiti akadai semacofferdams erwizi. Muchidimbu, mapombi esimbi ave chinhu chakakosha pakuvaka kwakawanda kweinjiniya nekuda kwezvakanakira zvavo zvakasiyana.
