Pamapurojekiti ekuvaka nekuvaka, kusarudzwa kwezvinhu zvinogona kukanganisa zvakanyanya kugara kwenguva refu uye kuvimbika kwechivako chekupedzisira. Pakati pezvinhu zvakasiyana-siyana zviripo, pombi yesimbi isina kusimba inoonekwa nekusiyana-siyana kwayo uye kusimba kwayo. Mublog rino, tichaongorora mashandisirwo akawanda epombi yesimbi isina kusimba, kunyanya kana tichitarisa mapaipi edu esimbi emhando yepamusoro, ayo akagadzirirwa kusangana nezvinodiwa zvekuvaka kwemazuva ano.
Simbi isina kusimba isarudzo yakakurumbira muindasitiri yekuvaka, inozivikanwa nekugona kwayo kupinza uye kugadzira zvakanaka. Inokwanisa kutsungirira mamiriro akasiyana-siyana ezvakatipoteredza uye yakakodzera kushandiswa kwakasiyana-siyana. Imwe yenzira dzinonyanya kushandiswa dzemapombi esimbi isina kusimba ndeyekuvaka macofferdams. Izvi zvivakwa zvenguva pfupi zvakakosha pakugadzira nzvimbo yakaoma yekushandira munzvimbo dzine mvura yakawanda kana dzinokurumidza kufashamira. Mapombi edu esimbi akagadzirwa zvakanyanya kuti ape kuvimbika uye kugara kwenguva refu kunodiwa pakushandisa kwakadai.
Kambani iyi iri muCangzhou, Hebei Province, yave iri mutungamiri muindasitiri yekugadzira simbi kubvira payakavambwa muna 1993. Kambani iyi ine nzvimbo inosvika 350,000 square metres uye ine tekinoroji yepamusoro-soro nemichina yekugadzira zvigadzirwa zvesimbi zvemhando yepamusoro zvinosangana nezvinodiwa pasi rose. Nehupfumi hwese hweRMB 680 miriyoni uye vashandi vakazvipira 680, kambani iyi yakazvipira kupa vatengi zvigadzirwa nemasevhisi akanaka kwazvo.
Hunhu hwakanaka ndicho chinhu chinonyanya kukosheswa nebhizinesi redu. Pombi yega yega yesimbi inoongororwa zvakanyanya kuti ive nechokwadi chekuti inosangana nezvinodiwa zvepamusoro. Kunyatsotarisa zvinhu zvakadzama uku kunopa vatengi vedu rugare rwepfungwa, vachiziva kuti vari kushandisa zvinhu zvakavimbika mumabasa avo ekuvaka. Pombi dzedu dzesimbi hadzina kugadzirirwa chete macofferdams, asiwo mamwe mashandisirwo akasiyana-siyana, anosanganisira rutsigiro rwenheyo, kuvaka gungwa, uye kugadzikana kwevhu.
Kuchinja-chinja kwepombi yesimbi yakapfavaHaingogumiri pakushandiswa kwayo chete. Inogona kuputirwa kana kugadziriswa zviri nyore kuti irambe yakasimba mukuora, zvichiita kuti ikodzere kushandiswa munzvimbo dzakaoma. Kuchinjika uku kunoita kuti mainjiniya nevanoita mabasa ekuvaka vashandise mapaipi esimbi asina kusimba mumapurojekiti akasiyana-siyana kubva pakuvaka dzimba kusvika pakuvaka zvivakwa zvikuru.
Pamusoro pezvo, kushanda zvakanaka kwepombi dzesimbi dzakapfava kunoita kuti ive sarudzo inokwezva mapurojekiti mazhinji ekuvaka. Kuwanikwa kwayo uye nyore kwayo kugadzira zvinobatsira kuderedza mari yevashandi uye kupfupisa nguva yepurojekiti. Nekuda kweizvozvo, nyanzvi zhinji dzekuvaka dziri kushandisa pombi dzesimbi dzakapfava semhinduro yakavimbika kune zvavanoda.
Mukupedzisa, kunzwisisa kushanduka-shanduka kwepombi dzesimbi dzakapfava kwakakosha kune chero munhu ari kuita zvekuvaka nekuvandudza zvivakwa. Mapombi edu esimbi anoratidza simba, kuvimbika uye kugona kuchinjika kwesimbi dzakapfava, zvichiita kuti dzive dzakakodzera kushandiswa kwakasiyana-siyana kusanganisira cofferdams. Nekuzvipira kwedu kune mhando uye hunyanzvi, ticharamba tichipa indasitiri yekuvaka zvigadzirwa zvinosangana nezvinodiwa zvepamusoro. Ungave uri kutanga chirongwa chitsva kana kutsvaga kuvandudza chivakwa chiripo, funga nezvemabhenefiti epombi dzesimbi dzakapfava uye rugare rwepfungwa runouya nekushandisa mapombi edu esimbi akagadzirwa nehunyanzvi.
