Yeduhombe dhayamita welded pombisndiwo musana weiyi mirwi yepombi yesimbi, inovandudza kuvimbika kwavo uye kushanda.Kuburikidza nehunyanzvi hwekushongedza uye maitiro ekudzora emhando, isu tinoona kuti murwi wega wega unosangana nemhando yepamusoro yeindasitiri.Mapombi aya anopa kuchinjika uye kusimba kwakasiyana-siyana, achibvumira mirwi yepombi yesimbi kuti imirire mamiriro akanyanya uye nharaunda dzakaoma.

Semugadziri anotungamira muindasitiri, Cangzhou Spiral Steel Pipes Group Co., Ltd. ine zvivakwa zvechizvino-zvino zvinofukidza nzvimbo inopfuura zviuru mazana matatu nemakumi mashanu emamita.Tine kukosha kweasset kunosvika 680 miriyoni yuan, tinodyara mukucheka-kumucheto tekinoroji nemidziyo kuti tive nechokwadi chekugadzirwa kwemhando yepamusoro.Uyezve, vashandi vedu vakazvitsaurira vevashandi mazana matanhatu nemakumi masere vanova nechokwadi chekuti chigadzirwa chese chinotariswa zvemhando yepamusoro chisati chasvika mumaoko evatengi vedu vanokoshesa.

Fekitori yedu ine goho repagore re400,000 matani espiral simbi mapaipi uye kukosha kwekubuda kwemabhiriyoni 1.8 yuan.Ichi chiitiko chakakosha chinoratidza kuzvipira kwedu kuunza kunaka kwesevhisi uye kusangana nezvinodiwa nevatengi vedu vanokoshesa munyika uye pasi rose.

Simbi pombi mirwiyakasanganiswa nedhayamita yedu yakakura welded mapaipi inopa yakanakisa versatility, ichiita kuti ive yakakodzera kune yakafararira yekushandiswa.Pamusoro pemacofferdam, mirwi yedu inoshandiswa zvakanyanya mukuvaka mabhiriji, zvivakwa zvechiteshi uye mamwe mapurojekiti emugungwa.Iyo yakasarudzika yakakomberedzwa kana yakatenderedzwa dhizaini yeaya mirwi inovimbisa yakakwana mvura uye kuchengetedza ivhu uku ichipa yakasimba chimiro chechimiro.

Kuzvipira kwekambani yedu kumhando, hunyanzvi uye kugutsikana kwevatengi kunotitungamira kuti tirambe tichivandudza maitiro edu ekugadzira uye kugadzira mhinduro nyowani.Isu tinoomerera kune yakasimba yemhando yekudzora zviyero kuti tive nechokwadi chekuti zvigadzirwa zvedu ndezvemhando yepamusoro uye zvinosangana kana kudarika zvaunotarisira.

Muchidimbu,simbi tubular mirwivari kushandura indasitiri yekuvaka nesimba uye kusimba kweyedu yakakura dhayamita yakashongedzwa pombi.Nekugona kwavo kumirisana nemamiriro ezvinhu akaoma uye kushandiswa kwavo kwakasarudzika mumakofidhamu, mirwi iyi inopa dziviriro nerutsigiro zvisingaenzaniswi.Batira pamwe neCangzhou Spiral Steel Pipes Group Co., Ltd. kuti uwane zvigadzirwa zvemhando yepamusoro zvinosimudzira mapurojekiti ako uye zvinopa mhinduro dzinogara kwenguva refu.
