Nhanganyaya yeChigadzirwa

Tichiunza mapaipi edu esimbi emhando yepamusoro emabasa ekuvaka, akagadzirirwa kusangana nezvinodiwa zvakasimba zvekuvaka kwemazuva ano. Yakagadzirwa mufekitori yedu yemazuva ano muCangzhou, Hebei Province, mapaipi edu esimbi anogadzirwa achishandisa zvinhu zvakanakisisa uye tekinoroji yepamusoro. Kubva patakavambwa muna 1993, takazvipira kuita zvakanaka uye tave vatungamiriri muindasitiri, tichifukidza nzvimbo inosvika 350,000 square metres uye pfuma yese inosvika RMB 680 miriyoni.

Mapombi edu esimbi akagadzirwa kuti ave akavimbika uye agare kwenguva refu, zvichiita kuti akwanise kushandiswa mumabasa akasiyana-siyana ekuvaka akadai seCofferdams. Pombi yega yega inoongororwa zvakanyanya kuti ive nechokwadi chekuti inosangana nezvinodiwa zvepamusoro-soro, zvichikupa rugare rwepfungwa pabasa rako rekuvaka. Nevashandi vane hunyanzvi mazana matanhatu nemakumi masere, tinokwanisa kubata mapurojekiti ehukuru hwese, tichipa chigadzirwa chisingangosviki pane zvinotarisirwa chete, asi chinodarika zvavanotarisirwa.

Ungave uri kushanda papurojekiti huru yekuvaka kana purojekiti diki yekuvaka, mapaipi edu esimbi emhando yepamusoro ndiwo mhinduro yakakwana kune zvaunoda. Vimba nemakore edu eruzivo uye kuzvipira kune mhando kuti zvikupe zvinhu zvakanakisa zvepurojekiti yako yekuvaka. Sarudza yedumurwi wepombi yesimbinekuda kwesimba radzo, kuvimbika kwadzo uye mashandiro adzo, uye kuona musiyano unogona kuitwa nezvinhu zvemhando yepamusoro muchirongwa chenyu chekuvaka.

Kubatsira Kwechigadzirwa

1. Zvichizivikanwa nekuvimbika uye kusimba kwadzo, mapaipi esimbi akanakira kushandiswa kwakasiyana-siyana kwekuvaka, senge cofferdams.

2. Kugadzirwa kwavo kwakasimba kunoita kuti pave nekuchengetedzeka uye kugadzikana kunodiwa pakugadzira nheyo nedzimwe nzvimbo dzekuvaka.

3. Simbi yemhando yepamusoro inoshandiswa mukugadzira mapaipi esimbi inovagonesa kutsungirira mitoro mikuru uye kurwisa zvinhu zvakaita sengura uye kufamba kwevhu.

4. Maitiro ekugadzira anoshandiswa nemakambani akaita seedu, ari muCangzhou, Hebei Province, anoita kuti murwi wega wega usvike padanho remhando yepamusoro, zvichipa makondirakiti nemainjiniya rugare rwepfungwa.

Kushaikwa kwechigadzirwa

1. Chimwe chezvinhu zvikuru inyaya yemutengo; simbi yemhando yepamusoro inodhura, izvo zvinogona kukonzera kuti bhajeti reprojekiti riwedzere.

2. Maitiro ekuisa anogona kuoma, achida michina yakasarudzika uye vashandi vane hunyanzvi, izvo zvinogona kuwedzera nguva yepurojekiti.

3. Kunyange hazvo mapaipi esimbi akasimba, anogona kubatwa nengura kana akasabatwa kana kuchengetwa zvakanaka.

Kushandiswa

Munyika yekuvaka iri kuramba ichichinja-chinja, kusarudzwa kwezvinhu zvine chekuita nekubudirira uye kugara kwenguva refu kwepurojekiti. Chimwe chezvinhu zvakaratidza kuti zvinokosha imapaipi esimbi emhando yepamusoro. Aya mapaipi esimbi anogadzirwa nokungwarira uye akakosha pakushandiswa kwakasiyana-siyana kwekuvaka, kunyanya pakugadzira hwaro hwakasimba uye kuona kuti chivakwa chacho chakasimba.

Yakagadzirwa uchishandisa zvinhu zvemhando yepamusoro uye tekinoroji yepamusoro,pombi yesimbiMapombi isarudzo yakavimbika kune chero basa rekuvaka. Dhizaini yavo yakasimba yekuvaka inobatsira zvikuru mumashandisirwo akadai seCofferdams, uko kugadzikana uye kuchengetedzeka zvakakosha. Mapombi aya anokwanisa kutsungirira mitoro inorema uye mamiriro ekunze akaomarara, zvichiita kuti ave sarudzo inofarirwa nemainjiniya nevanovaka.

Mukupedzisa, kushandisa mapaipi esimbi emhando yepamusoro kwakakosha kuti chirongwa chekuvaka chibudirire. Kuvimbika kwavo, kusimba kwavo, uye maitiro avo ekugadzira epamusoro zvinoita kuti zvive zvakanaka kumapurojekiti enheyo nezvivakwa. Sezvatinoramba tichigadzira zvinhu zvitsva nekuvandudza zvigadzirwa zvedu, tinoramba takazvipira kutsigira indasitiri yekuvaka nezvinhu zvakanakisisa. Sarudza mapaipi edu esimbi epurojekiti yako inotevera uye ona musiyano wemhando uye mashandiro.

Mibvunzo Inowanzo bvunzwa

Mubvunzo 1: Chii chinonzi mapaipi esimbi?

Mapombi esimbi zvivakwa zvesimbi zvakagadzirwa nesimbi yemhando yepamusoro, zvakagadzirirwa kurovererwa pasi pasi kuti zvitsigire hwaro. Zvinogadzirwa uchishandisa tekinoroji yepamusoro kuona kuti zvinosangana nezvinodiwa nemapurojekiti akasiyana-siyana ekuvaka.

Mubvunzo wechipiri: Sei uchifanira kusarudza mapaipi esimbi ekuvaka?

Mapombi esimbi anozivikanwa nekusimba kwawo uye kugara kwenguva refu. Magadzirirwo awo akasimba anoita kuti akwane kuma cofferdams uko kugadzikana kwakakosha zvikuru. Mapombi aya anogona kutsungirira mitoro inorema uye mamiriro ekunze akaoma, zvichiita kuti ave sarudzo yakavimbika yenheyo nemamwe mapurojekiti ezvivakwa.

Mubvunzo 3: Kambani yenyu iri kupi?

Kambani yedu yakavambwa muna 1993 uye iri muCangzhou City, Hebei Province. Iine nzvimbo inosvika 350,000 square metres, ine midziyo inosvika 680 miriyoni yuan, uye parizvino ine vashandi 680. Takazvipira kugadzira mapaipi esimbi emhando yepamusoro anoenderana nezvinodiwa nevatengi.

Mubvunzo wechina: Ndeapi matanho ekusimbisa mhando aunoita?

Tinotarisa pamhando yepamusoro padanho rega rega rekugadzira. Mapombi edu esimbi anogadzirwa achishandisa zvinhu zvemhando yepamusoro uye anoshandisa tekinoroji yepamusoro kuti ave nechokwadi chekuti akavimbika. Maitiro edu ekudzora mhando anovimbisa kuti zvigadzirwa zvedu zvinosangana nezvinodiwa neindasitiri uye zvinodiwa nevatengi.

Yakapfuura: Mapaipi eSimbi Anoshandiswa Nemhando Dzese Ekushandisa Mumaindasitiri

Zvinotevera: Tambo yeMapaipi eMoto Yakavimbika Kuti Igutse Zvaunoda Zvekuchengetedza
