Vanhu vazhinji havasati vambonzwa nezve tekinoroji isina trench pfuti yekugadzirisa tekinoroji nekuti zita rayo rakareba uye rakati vhiringike, asi mukurumbira wayo wepasirese unoshamisa. U.S. Highway Strategic Research Program inoidaidza kuti inogara kwenguva refu. uye nzira dzekugadzirisa dzinoshanda.
American Highway Strategic Research Chirongwa? The U.S. Strategic Highway Research Programme ndiyo hombe mugwagwa mukuru wekutsvagisa chirongwa pasi rose kusvika parizvino. Mushure menguva refu yekudzidzira, vaongorori vakawana kuti tsika dzechinyakare dhizaini uye nzira dzekuyedza dzakasiyana nemamiriro chaiwo. Zvimwe zvinetso zvinomuka panguva yebasa zvakaoma kutsanangura nemafungiro echinyakare. Zvinonyanya kukosha kuita tsvakiridzo yesainzi uye yakarongeka kugadzira seti mitsva yemitemo uye zviyero zvekugadzira, kuyedza uye kugadzirisa kwekuvaka kuzadzisa zvinodiwa pakuvaka mugwagwa mukuru.

Nei ruzivo rwokugadzira pfuti ruine mukurumbira wakasimba zvokuti madhipatimendi anozivikanwa zvikuru muUnited States azere nokururumbidza nokuda kwarwo?
Iyo isina trenchless trench pfuti yekugadzirisa yekuvaka tekinoroji inoshandisa yakakwirira-yakadzika uye yakakwirira-viscosity mvura-yakavakirwa polymer inoumba zvinhu sechinhu chinosungirirwa, uye yakashambidzwa imwe-grained gravel seyakaunganidzwa. Migero yacho inocheneswa nemhepo ine simba guru uye yakapfapfaidzwa nezvinhu zvekubatanidza. Iwo mana ekuvaka maitiro ekusanganisa uye kupfapfaidza adhesive layer mafuta, bonding material uye aggregate, uye kupfapfaidza kurapa zvinhu zvinosanganiswa mumuchina mumwe wekugadzirisa pfuti. Gadzirisa zvachose makatsemuka, makatsemuka, maduku, uye makomba ari paasphalt uye simende pavevement.
Kwete izvozvo chete, tekinoroji yekugadzira pfuti isina pfuti ine huwandu hwakasiyana hwemashandisirwo, kusanganisira yakakwirira-kumhanya, yekutanga-kirasi, yechipiri-kirasi, County uye mataundi migwagwa; asphalt, simende, migwagwa yematombo uye mamwe migwagwa; mutengo wekuvaka wakaderera uye unogona kuchengetedza 50% zvinhu; iyo yekumhanyisa yekumhanyisa inokurumidza, uye inogona kuvhurwa kune traffic nekukurumidza mushure mekugadzirisa kuderedza yakavharwa traffic traffic; kana yangogadziriswa, hapana chikonzero chekugadzirisa zvakare, uye hupenyu hwebasa hwakareba semakore 5-10.
Vamwe vanhu vanogona kufunga kuti zviri pamusoro apa zvakawedzeredzwa, asi zvivakwa izvi zvinozivikanwa neUS Highway Strategic Research Chirongwa uye zvinozivikanwa nazvo seyakanyanya kusimba uye inoshanda nzira yekugadzirisa. Zvinogona kuonekwa kuti ine "chaiwo kugona" kwayo. Unofungei?
