Matanda esimbi, sechishandiso chekutsigira chimiro chinosanganisa simba nekuchinjika, anoita basa risingatsiviwi mumapurojekiti ekuchengetedza mvura, kuvaka kwakadzika kwenheyo, kuvaka chiteshi chengarava, nedzimwe nzvimbo. Mhando dzadzo dzakasiyana-siyana, maitiro ekugadzira akaomarara, uye kushandiswa kwakawanda pasi rose zvinoita kuti zvive chinhu chakakosha pakuona kuchengetedzeka uye kuvandudza kushanda zvakanaka mukuvaka. Chinyorwa chino chichapa ongororo yakadzama yemhando dzematanda esimbi, misiyano yawo, nzira dzekugadzira dzakajairika, uye saizi dzakajairika uye zvirevo, zvichipa ruzivo rwakakwana kune vanoita zvekuvaka nevatengi.
Matanda esimbidzakarongwa zvichienderana nechimiro chepakati. Mapombi esimbi emhando yeZ- neU ndiwo anonyanya kusarudzwa muinjiniya nekuda kwekushandiswa kwawo kwakasiyana-siyana uye zvakanakira mashandiro awo. Zvisinei, pane musiyano wakakura pakati pemhando mbiri idzi maererano nechimiro, mashandiro, uye mamiriro ekushandiswa:
Matanda esimbi akaita seU: Dzine chimiro chakaita semugero wakavhurika une mipendero inokiya kuti ikwane zvakanaka, zvichivabvumira kuti vagone kuchinja zvinoenderana nezvinodiwa zvikuru zvekuchinja-chinja mumapurojekiti einjiniya. Hunhu hwavo hwakanaka hwekuchinja-chinja hunoita kuti dzishandiswe zvakanyanya mumapurojekiti ehydraulic ane mvura yakawanda (akadai sekutarisira rwizi nekusimbisa reservoir embankment) uye rutsigiro rwegomba renheyo rakadzika (sekuvaka pasi pevhu kwezvivakwa zvirefu). Pari zvino ndidzo mhando dzesimbi dzinonyanya kushandiswa pamusika.
Matanda esimbi akaita seZ: Dzine chikamu chakavharwa, chine zigzag cross-section chine maplate esimbi akakora kumativi ese, zvichikonzera modulus yechikamu chakakwirira uye kuomarara kwakanyanya. Izvi zvinobvumira kudzora kwakanyatsojeka kwekushanduka kwemainjiniya uye zvakakodzera kumapurojekiti epamusoro ane zvinodiwa zvakasimba zvekudzora kukanganiswa (senge makomba efactory foundation uye kuvaka bridge foundation hombe). Zvisinei, nekuda kwekuoma kwehunyanzvi hwekumonera kusina kuenzana, makambani mana chete pasi rese ane kugona kugadzira, zvichiita kuti rudzi urwu rwemurwi wepepa ruve rushoma.
Maitiro ekugadzira mapurasitiki esimbi anokanganisa zvakananga mashandiro awo uye mashandisirwo azvo. Parizvino, kutenderedza kupisa uye kukotama kunotonhora ndiyo nzira mbiri huru dzinoshandiswa muindasitiri, imwe neimwe iine chinangwa chayo chakasiyana mumaitiro ekugadzira, hunhu hwechigadzirwa, uye nzvimbo yekushandisa:
Matanda esimbi anomonerwa nekupisaZvinogadzirwa nesimbi, zvinodziiswa kusvika pakupisa kwakanyanya, uye zvobva zvakungurutswa kuita chimiro uchishandisa michina yakasarudzika. Chigadzirwa chapedzwa chinopa kunyatsokiya kwakanyanya uye simba rakawanda, zvichiita kuti chive chigadzirwa chinotungamira mumapurojekiti einjiniya. Royal Steel Group inoshandisa nzira yekumonera yakatevedzana kuti ipe mapairi akaita seU ane upamhi hwe400-900mm uye mapairi akaita seZ ane upamhi hwe500-850mm. Zvigadzirwa zvavo zvakashanda zvakanaka kwazvo paShenzhen-Zhongshan Tunnel, zvichivawanisa mukurumbira we "kudzikamisa mapairi" kubva kumuridzi wepurojekiti, zvichiratidza zvizere kuvimbika kwemaitiro ekumonera anopisa.
Matanda esimbi akaumbwa nechandoDzinoumbwa netambo dzemumba, zvichibvisa kudiwa kwekugadzirisa tembiricha yepamusoro. Izvi zvinoita kuti dzive dzakatsetseka uye dzisarambe dzichipisa ne30%-50% kupfuura dzinopisa. Dzakakodzera kushandiswa munzvimbo dzine hunyoro, dziri pamhenderekedzo yegungwa, uye dzinokurumidza ngura (semuenzaniso, kuvaka gomba renheyo). Zvisinei, nekuda kwekusakwana kwemaitiro ekugadzira tembiricha yemumba, kuomarara kwadzo kwechikamu chimwe chete hakuna kusimba. Dzinonyanya kushandiswa sezvinhu zvekuwedzera, pamwe chete nemapombi anoputika nemoto kuti pave nemutengo wepurojekiti uye mashandiro ayo.
Mhando dzakasiyana dzemapuranga esimbi dzine zviyero zvakajeka. Kutenga mapurojekiti kunofanirwa kufunga nezvezvinodiwa (sekudzika kwekuchera uye kusimba kwemutoro) kuti vasarudze zvinodiwa zvakakodzera. Izvi zvinotevera zviyero zvakajairika zvemhando mbiri dzemapuranga esimbi:
Matanda esimbi akaita seU: Chimiro chakajairika chinowanzova SP-U 400×170×15.5, ane upamhi hunotangira pa400-600mm, ukobvu hunobva pa8-16mm, uye hurefu hwe6m, 9m, uye 12m. Kune zvinodiwa zvakakosha zvakaita sekuchera kwakakura, kwakadzika, mamwe matanda eU akaputirwa nemoto anogona kugadziriswa kuti asvike pa33m kuti aenderane nezvinodiwa zvekutsigira zvakadzama.
Matanda esimbi akaita seZ: Nekuda kwemiganhu yemaitiro ekugadzira, saizi dzacho dzakafanana, nehurefu hwakasiyana hunobva pa800-2000mm uye ukobvu hunobva pa8-30mm. Hurefu hwakajairika hunowanzova pakati pe15-20m. Maitiro akareba anoda kubvunzana nemugadziri kuti ave nechokwadi chekuti maitiro acho anogona kushanda.
Kubva kuzviteshi zveSoutheast Asia kusvika kunzvimbo dzinochengetedza mvura dzeNorth America, simbi dzakaita sema "steel sheet pills", pamwe nekugona kwadzo kuchinjika, dzave dzichishandiswa mumapurojekiti akasiyana-siyana pasi rose. Izvi zvinotevera zvidzidzo zvitatu zvakajairika kubva kuvatengi vedu, zvichiratidza kukosha kwazvo:
Chirongwa Chekuwedzera Chiteshi chengarava chePhilippines: Munguva yekuwedzera kwechiteshi chengarava muPhilippines, njodzi yekukwira kwemvura ine dutu inokonzerwa nemadutu anowanzoitika yairatidzika. Dhipatimendi redu rehunyanzvi rakakurudzira kushandiswa kwemapuranga esimbi ane chimiro cheU-shaped hot-rolled steel sheet piles paCofferdam. Nzira yavo yekukiya yakasimba yakabudirira kudzivirira kukanganiswa kwemvura ine dutu, ichivimbisa kuchengetedzeka nekufambira mberi kwekuvakwa kwechiteshi.
Chirongwa chekudzoreredza nzvimbo yekuchengetedza mvura muCanada: Nekuda kwechando chinotonhora panzvimbo yenzvimbo yekuvaka, ivhu rinowanzo shanduka-shanduka nekuda kwechando, zvichida kugadzikana kwakanyanya. Dhipatimendi redu rehunyanzvi rakakurudzira kushandiswa kwemapuranga esimbi ane chimiro cheZ-shaped hot-rolled steel sheet kuti asimbiswe. Simba rawo rakakombama rinogona kutsungirira kushanduka-shanduka kwesimba revhu, zvichiita kuti nzvimbo yekuchengetedza mvura ishande zvakanaka kwenguva refu.
Chirongwa chekuvaka chivakwa chesimbi muGuyana: Panguva yekuvaka gomba renheyo, chirongwa ichi chaida kudzorwa kwakasimba kwekushanduka kwemawere kuti ive nechokwadi chekuti chivakwa chikuru chakachengeteka. Muvaki akachinja kuita machira edu esimbi akagadzirwa nechando kuti asimbise gomba renheyo, achibatanidza kuramba kwavo ngura uye kugona kwavo kuchinjika nemamiriro ekunze ane hunyoro kuti vapedzise chirongwa ichi zvinobudirira.

Ingave iri purojekiti yekuchengetedza mvura, purojekiti yechiteshi, kana rutsigiro rwegomba renheyo yekuvaka, kusarudza mhando yemurwi wesimbi, maitiro, uye zvinodiwa zvakakosha kuti uve nechokwadi chekuti purojekiti yako ndeyemhando yepamusoro. Kana uchironga kutenga mirwi yesimbi yepurojekiti yako, kana kuti uchida tsanangudzo dzakadzama dzezvigadzirwa, sarudzo dzekugadzirisa, kana mitengo yazvino, ndapota inzwa wakasununguka kutibata. Tichapa mazano ehunyanzvi ekusarudza uye mitengo chaiyo zvichienderana nezvinodiwa nepurojekiti yako, tichiona kuti purojekiti yako inofambira mberi zvakanaka.
