Ho hahoa ha Lile River Bridge

Khampani ea rona e fana haholo ka likhoele tsa tšepe tse hahelletsoeng pele bakeng sa ho etsa marokho a konkreite le likhoele tsa ho lula bakeng sa litora tse khutšoane tsa borokho bo kentsoeng morerong ona.

1. The superstructure ea borokho ka sehloohong ke ka mokgwa wa prestressed konkreite feto-fetoha sefapano karolo lebokose girder, bophara ba borokho ka sehloohong ke 33,5 limithara tse. Borokho ba ho atamela bo entsoe ka li-slats, ka bophara bo le bong ba limithara tse 12,5, borokho bo atamelang bo nka sebopeho sa girder se senyenyane sa 30-meter span. Borokho ba Lile River bo bolelele ba limithara tse 30, 'me boima ba girder ea lebokose le le leng ke lithane tse 100.

2. Mohala o ts'oaretsoeng o entsoe ka 15-91 epoxy sprayed steel strand e nang le tšireletso ea HDPE e nang le likarolo tse peli, bophara ba khoele e le 'ngoe φ15.2mm, matla a thata a fpk = 1860MPa. (boleng bo tloaelehileng)

3. Thepa ea mochini oa likhoele tsohle tsa tšepe tse hatelitsoeng pele tse sebelisitsoeng morerong li lumellana le lipehelo tsa "Steel Strands for Prestressed Concrete"(GB/T5224-2014) le EN10138-3:2009, thepa ea bona e thibelang kutu e fihlela litlhoko tsa ASTM. A882/A882M-02a le ISO 14655:1999. Ho hanyetsa mokhathala oa cable e lutseng ho lokela ho finyella moeli o ka holimo oa khatello ea kelello σmax = 0.45fptk, amplitude ea khatello ea kelello ea 200MPa, le tekanyo ea ho robeha ha terata ea ≤2% ka mor'a lipotoloho tse limilione tse 2.

Likhoele tsa 1.Prestressed concrete (PC) li atisa ho sebelisoa ha ho hahoa maballo a konkreite ho fana ka matla a thata le ho matlafatsa.

2.Likhoele tsena hangata li tsitsitse pele kapa ka morao ho tsitsipano ka har'a konkreite ho eketsa matla a ho jara le ho fokotsa ho phunyeha.

3.Tšebeliso ea likhoele tsa PC e thusa ho ntlafatsa ts'ebetso ea kakaretso ea sebopeho le ho tšoarella ha maballo a konkreite. Likhoele tsa konkreite tse hahelletsoeng (PC) li atisa ho sebelisoa ha ho hahoa maballo a konkreite ho fana ka matla le ho matlafatsa.
