Munzvimbo iri kuramba ichichinja-chinja yeindasitiri yesimba, kudiwa kwemhinduro dzezvivakwa zvinoshanda uye zvakavimbika ndiko kwakakosha. Imwe yenzira dzakabudirira zvikuru mundima iyi ikushandiswa kwehunyanzvi hwe spiral submerged arc pipe (SSAW). Pamberi pekuvandudzwa uku pane A252 Grade 3 Steel Spiral Submerged Arc Pipe, chigadzirwa chisingangosviki chete asi chinodarika mwero weindasitiri, chichiisa chiyero chitsva chemhando yepamusoro uye kushanda zvakanaka.
Iri muCangzhou, Hebei Province, kambani iyi yave iri kutungamira muindasitiri yekugadzira mapaipi kubvira payakavambwa muna 1993. Kambani iyi ine nzvimbo inosvika 350,000 square metres, ine tekinoroji yepamusoro-soro, uye ine vashandi vehunyanzvi 680. Mari yese yekambani iyi inosvika RMB 680 miriyoni, uye takazvipira kuita tsvakurudzo nekuvandudza kuti tive nechokwadi chekuti zvigadzirwa zvedu zvinogara zviri pamberi peindasitiri iyi.
Simbi yeGiredhi 3 yeA252Pipe yeArc Yakanyudzwa neSpiralYakagadzirwa kuti iite basa rakanaka mumabasa akasiyana-siyana, kunyanya muchikamu chesimba. Dhizaini yayo yakasiyana inopa simba rakawedzerwa uye kuchinjika, zvichiita kuti ive yakakodzera kutakura mvura nemagasi pakumanikidzwa kwakanyanya. Iyi pombi itsva haina kusimba uye inogara kwenguva refu chete, asiwo yakareruka, izvo zvinoita kuti kuiswa kuve nyore uye kuderedza mari yepurojekiti.
Chimwe chezvakanakira zvikuru zvemapaipi edu eSSAW kugona kwawo kutsungirira mamiriro ekunze akaoma. Indasitiri yesimba inowanzo shanda munzvimbo dzakaoma, kungave kuri kucherwa kwemvura, kutakurwa kwegasi kana mapurojekiti esimba rinodzokororwa. Mapaipi edu akagadzirwa kuti agone kutsungirira mamiriro aya, zvichiita kuti agare kwenguva refu uye akavimbika zvakanyanya. Maitiro ekugadzira epamusoro atinoshandisa anoratidza kufambira mberi kwetekinoroji, zvichitibvumira kugadzira mapaipi asingangoshande zvakanaka chete asiwo ane hushamwari kune nharaunda.
Pamusoro pezvo,A252 Giredhi 3 Steel Pipeinogadzirwa ichinyanya kutarisa pakuchengetedza nharaunda. Sezvo indasitiri yesimba iri kuramba ichienda kune tsika dzekuchengetedza nharaunda, mapaipi edu anobatsira mukufamba uku nekuderedza marara uye kuderedza kukanganiswa kwekabhoni kunobatanidzwa nekugadzirwa kwemapaipi echinyakare. Kuzvipira uku kwekuchengetedza nharaunda kunoenderana nekuedza kwenyika dzese kurwisa shanduko yemamiriro ekunze nekusimudzira manejimendi ane hungwaru.
Pamusoro pekushandiswa kwayo muchikamu chemagetsi, mapaipi edu eSSAW anogona kushandiswa zvakasiyana-siyana uye anogona kushandiswa mune mamwe maindasitiri akasiyana-siyana, kusanganisira mvura, masisitimu etsvina, uye kuvaka. Kuchinjika uku kunoita kuti ive chinhu chakakosha kune chero chirongwa chinoda mhinduro yemapaipi yakavimbika.
Tichitarisa ramangwana, kambani yedu inoramba yakazvipira mukuvandudza zvinhu zvitsva uye kugona. Tinonzwisisa kuti indasitiri yesimba iri kuramba ichichinja, uye takazvipira kuramba tiri pamberi pechinjo. Nekuramba tichivandudza maitiro edu ekugadzira uye kuisa mari mumatekinoroji matsva, chinangwa chedu ndechekupa vatengi vedu zvigadzirwa zvemhando yepamusoro zvinoenderana nezvinodiwa zvavo zvinochinja.
Muchidimbu, kushandiswa kutsva kwepombi yesimbi inoyerera mudenga, kunyanya simbi yeA252 Grade 3, kuri kuchinja indasitiri yesimba. Nesimba rayo guru, kuchinjika uye kugara kwenguva refu, chigadzirwa ichi chinoisa mitemo mitsva yekushanda zvakanaka uye kuvimbika. Sekambani ine hunyanzvi uye mhando, tinodada nekubatsira mukusimudzira indasitiri yesimba uye tinotarisira kutamba basa guru mukuvandudzwa kwayo mune ramangwana. Kunyangwe uri muchirongwa chemafuta negasi, simba rinogona kushandiswazve kana mapurojekiti ezvivakwa, pombi yedu yeSSAW mhinduro yaunogona kuvimba nayo.
