Shamwari dzakamboshanda panzvimbo dzekuvaka dzinoziva kuti chii chinonyanya kutyiwa pakuvaka embankment? Kubuda kwemvura.
Kana mipata iri pakati pemakomba ikasagona kuvharwa zvakanaka, mvura inotakura madhaka inonyura. Gomba repasi rinozoshanduka kuita "gomba remvura", uye kuedza kupomba mvura kunozokundikana. Purogiramu yepurojekiti ichanonoka zvakare. Ndokusaka mapurojekiti akawanda, pakusarudzaMapaipi Ekubatanidza Kuvhara Kuvhara, isa "sealing performance" pakutanga.
Mirwi yesimbi yechinyakare kana mirwi yemapaipi yakatenderera inowanzova nemipata midiki pajoini nekuda kwekutsauka kwekuvaka. Kana mvura yakakwira kana ikasangana nekuchinja kwemvura, kubuda kwemvura hakudzivisiki. Zvisinei, mirwi yemapaipi yakagadzirirwa kuvharwa kwekubatanidza ine migero yakatsaurirwa yekuvhara uye zvivakwa zvekukiya kumativi ese emuviri wemurwi. Munguva yekuunganidzwa kwemurwi, mapaipi maviri ari pedyo anobatana, uye nezvinhu zvinomisa mvura, zvinogona "kusabuda mvura zvachose".
Ngatitaurei nezve chimiro -Mapombi eSimbi ane Maumbirwo eCylindrical, ayo ari mapaipi esimbi akatenderera. Sei ari mapaipi akatenderera? Chikonzero chacho chiri nyore: Chikamu chakatenderera chine kuomarara kwakafanana kwekukombama kumativi ese. Munguva yekuronga, simba rinoparadzirwa zvakaenzana, uye kashoma kuti ritsauke. Panguva imwe chete, pamusoro pedenderedzwa pane kupararira kwakanaka kwekudzivirira kukweshana muvhu, uye kugona kwekutakura murwi mumwe chete kwakakwira kupfuura kwemapaipi akatenderera ane chikamu chimwe chete. Kana ikashandiswa mucofferdams, haingovhari mvura chete asiwo inorema, ichiwana mabhenefiti maviri nemhinduro imwe chete.
Boka redu reCangzhou Spiral Steel Pipe Group rave riri muindasitiri iyi kwemakore anopfuura makumi matatu (rakatangwa muna 1993, riine kugona kwekugadzira matani 400,000 pagore uye midziyo ye680 miriyoni yuan). Chimwe chiitiko chakadzama chatakawana ndechekuti pamapombi esimbi anoshandiswa mucofferdam, munhu haafanire kungofunga nezveukobvu hwemadziro nedhayamita, asi kunyatsogadzirisa zvikamu zvinobatana chiratidzo chechokwadi chekuvimbika. Kana nzira yekukiya isina kumira zvakanaka kana kuti gomba rekuvhara rakadzikira ne0.5 millimeters, harizokwanisi kubatana zvakasimba kana rakaiswa panzvimbo yacho.
Saka nguva inotevera paunenge uchigadzira cofferdam kana hurongwa hwekutsigira gomba rakadzika, wadii kuzvibvunza mubvunzo uyu: Zvisimbiso zvinobatana zvemapombi aya esimbi akasimba zvinovimbika here? Kana ukasarudza akakodzera, unogona kuchengetedza mamiriyoni emadhora emari yekugadzirisa kudonha kwemvura mune ramangwana - izvi hazvisi zvekuwedzeredza, asi ndezvechokwadi pakuvaka panzvimbo yekuvaka.
