Ufakelo olufutshane kunye nexesha lokwakha
Umbhobho wentsimbiIkholveti yenye yobuchwepheshe obutsha obukhuthazwayo kwiiprojekthi zobunjineli bendlela enguhola kule minyaka yakutsha nje, yi-2.0-8.0mm yokuqina okuphezulu kwepleyiti yentsimbi ecinezelwe kwintsimbi emdaka, ngokomlinganiselo wombhobho owahlukileyo oqengqeleke kwicandelo lombhobho ukuze ubuyisele ikholveti eyomeleziweyo yekonkrithi. Ixesha lofakelo lwekholvethi yombhobho oxonxiweyo ziintsuku ezi-3 ukuya kwezi-20 kuphela, xa kuthelekiswa nekholvethi yokugquma yekhonkrithi, ikholvethi yebhokisi, ukonga ngaphezu kwenyanga e-1, uluhlu olubanzi lwezicelo, izibonelelo zentlalo nezoqoqosho.
Ukuchasana okunamandla kwi-deformation kunye nokuhlaliswa
Uhola wendlela eyakhiwe kwindawo engumngxuma wokumbiwa kwamalahle, ngenxa yemigodi engaphantsi komhlaba inokubangela ukuba umhlaba ube ngamanqanaba ahlukeneyo okuhla, okukhokelela ekuhlalweni okungalinganiyo, ukubunjwa kwesamente ngokubanzi kweedigri ezahlukeneyo zomonakalo. Intsimbiimibhobho yentsimbiI-culvert iyisakhiwo esiguquguqukayo, umbhobho wensimbi odibeneyo kwisakhiwo sembuyekezo yecala lokufuduka kweempawu ezibalaseleyo, unokunika umdlalo opheleleyo kwiipropati eziqinileyo zentsimbi, ukuguqulwa kweempawu zokusebenza okuphezulu, kunye nokuchasana okukhulu kwi-deformation kunye ne-deformation. indawo yokuhlala. Ngokukodwa ilungele umhlaba othambileyo, umhlaba odumbileyo, isiseko selahleko emanzi esithwala umthamo weendawo eziphantsi kunye neendawo ezithandwa ziinyikima.
Ukumelana nomhlwa okuphezulu
Ikholvethi yombhobho exonxiweyoinokumelana nomhlwa okuphezulu kunekholvethi yombhobho eqinisiweyo yemveli eyomeleziweyo. Amalungu emibhobho ashushu afakwe idiphu kwaye amazibuko afafazwe nge-asphalt kunyango lokuchasa umhlwa. Isombulula ingxaki yomonakalo kwisakhiwo sekhonkrithi kwiindawo ezimanzi nezibandayo, kwaye ubomi bokusebenza obusebenzayo bude kunobo beekholvethi zemveli.
Ukukhuselwa kwendalo kunye nekhabhoni ephantsi
Ikholvethi yemibhobho yentsimbi egutyungelweyo inciphisa okanye iyeke ngokulula ukusetyenziswa kwezinto zokwakha eziqhelekileyo, njengesamente, isanti ephakathi kunye nerhabaxa, igrabile, iinkuni. Ikholvethi yombhobho wentsimbi eyenziwe ngezinto eziluhlaza nezingangcolisi, nto leyo enceda ukukhuselwa kwendalo kunye nokunciphisa ukukhutshwa kwekhabhoni.
Ixesha lokuvula ngokukhawuleza kunye nokugcinwa lula
Ikholvethi yombhobho wentsimbi egutyungelweyo ukusuka ekugrunjweni ukuya kwi-backfill ingagqitywa ngosuku olunye, xa kuthelekiswa nesakhiwo sekonkrithi esomeleziweyo semveli, sigcina kakhulu ixesha lokwakha, ukuze ixesha lokusetyenziswa kweendleko nalo lincitshiswe kakhulu. Ikholvethi yentsimbi yombhobho yentsimbi egudileyo ukugcinwa kwayo kukulungele, kwindawo enkulu yokusingqongileyo kwaye nangaphandle kokugcinwa, ukwenzela ukuba iindleko zokulondoloza zincitshiswe kakhulu, iinzuzo zoqoqosho zibalaseleyo.
Shwankathela
Ikholvethi yentsimbi yombhobho yentsimbi kubunjineli bendlela inexesha elifutshane lokufakela kunye nokwakhiwa, ixesha lokuvula ngokukhawuleza, ukugcinwa lula, i-carbon ephantsi kunye nokukhuselwa kwendalo, ukuxhathisa okuphezulu kwe-corrosion, ukuxhathisa okuphezulu kwi-deformation kunye nokuxhathisa ukubola. Ekwakhiweni kweeprojekthi zohola wendlela, ukusetyenziswa kombhobho we-corrugated culverts kunokukwenza ukuba ukusebenza kokuthutha kwendlela kungachaphazeleki, kodwa nokomeleza ukusetyenziswa kwayo kwiprojekthi yokulondoloza, izibonelelo zentlalo zibalulekile.
