Matanda esimbi akaita seUchikamu chakakosha chemapurojekiti akasiyana-siyana ekuvaka, kunyanya muminda yeinjiniya yezvivakwa nekuvandudza zvivakwa. Makomba aya akagadzirirwa kutsigira chimiro uye kuchengetedza ivhu, zvichiita kuti ave chikamu chakakosha chemadziro ekuchengetedza, macofferdams, nezvimwe zvivakwa zvekuchengetedza.
Matanda esimbi akaita seU, anozivikanwawo seMirwi yeU-sheet, ine chimiro chakasiyana cheU-shaped cross-sectional. Chimiro ichi chakasiyana chine zvakanakira zvakawanda, zvinosanganisira kusimba kwakanyanya kukotama uye kuramba mvura zvakanaka, zvichiita kuti zvikwanise zvivakwa zvechigarire nezvechinguva. Dhizaini yakabatana yemaU-sheet piles inobatsira kuisa uye inovimbisa kugadzikana uye kunaka uku ichichengetedza mhando dzakasiyana dzevhu nemvura. Anowanzoshandiswa mukudzivirira mahombekombe, kusimbisa mahombekombe erwizi, uye kuvaka pasi pevhu.
Maitiro ekuisa ma sheet piles akaita seU anoshandisa michina yakakosha senge hydraulic hammers kana vibratory hammers kuti arovere ma piles muvhu, uye nzira yekukiya ma piles inoita kuti avharwe zvakasimba kudzivirira mvura kunyura uye kuchengetedza kugadzikana kwechivakwa. Nzira iyi yekuvaka inoshanda uye inoderedza kukanganisa kwezvakatipoteredza, zvichiita kuti ma piles akaita seU ave sarudzo inogara kwenguva refu yekuchengetedza madziro.
Pamusoro pezvo, machira uye ma sealant zvinogona kushandiswaMirwi yemashizha yakaita seUkuwedzera simba radzo rekudzivirira ngura uye kuwedzera nguva yadzo yebasa, kunyanya munzvimbo dzegungwa nedzevhu dzinokanganisa ngura.
