Lithapo tse tšoanang tsa strand/Lithapo tsa Bridge tsa Suspension
Selelekela
Parallel strand cable/Suspension Bridge Cables ke thapo e entsoeng ka likhoele tse ngata tsa tšepe tse bapileng. Hangata likhoele tsena lia sotheha kapa li lohiloe hammoho ho etsa thapo e matla empa e tenyetseha. Parallel strand cable e tsejoa ka matla a eona a phahameng, ho tšoarella le ho hanyetsa ho otlolla. Lithapo tsa borokho tse emisitsoeng li phetha karolo e kholo kahong ea borokho. Li lokela ho ba tse matla le tse ka tšeptjoang e le hore li ka nkoa e le tšebeliso. Re hlahisa lithapo tse emisitsoeng tsa boleng bo holimo haholo tse ka tšeptjoang ka lilemo tse ngata tsa tšebeliso e tšepahalang.
Ntle le moo, substrate ea tšepe ea strand cable system haholo-holo e nka φ15.2mm orφ15.7mm, matla a tloaelehileng a 1860MPa, modulus elastic ea 1.95 x 105MPa e sebelisa khoele ea tšepe joalo ka motheo oa thapo, ts'ebetso ea tšepe e kopana le litlhoko tsa machaba tsa EN10138 , ASTM A416 le GB / T5224-2003.
Litšobotsi tsa khoele ea tšepe e nang le Double-layer PE e sa tlanngoeng:
Steel Strand ho ea ka mefuta e fapaneng ea anti-corrosion e arotsoe ka mefuta e 'meli ea likhoele tsa tšepe le epoxy coated steel strand surface-anti-corrosion, ka mor'a ho ba khahlanong le kutu, ebe ka oli ea corrosion ka ntle ho khoele ea tšepe ea PE sheathed unbonded strand. , le Tšireletso ea PE e chesang e chesang ea tšepe ea tšepe e sa tsitsang habeli ea PE e le ho finyella ts'ebetso e ntle ea ho thibela ho bola.
Khoele ea tšepe ea PE e sa kopaneloang habeli ea PE e na le ts'ebetso e ts'oanang ea ts'ireletso joalo ka likhoele tse ling tsa tšepe tsa PE, haholo-holo tse etselitsoeng thapo ea tšepe e ka nkeloang sebaka. Mohala oa tšepe oa PE o na le lera le letenya la 2mm pakeng tsa polyethylene layer C le polyethylene layer d, ho fokotsa likhohlano lipakeng tsa likarolo tse peli tsa polyethylene le ho bapala karolo e ka nkeloang sebaka. Mohala o entsoeng ka PE strand e joalo e ka nkeloa sebaka ke PE e le 'ngoe.
Ho sa tsotelehe hore na ke mofuta ofe oa likhoele tsa tšepe tse thibelang kutu, likhoele tse ngata tsa tšepe hammoho bakeng sa kalafo ea ho loha ka terata, 'me ka mor'a moo ka lisebelisoa tsa HDPE tse kopantsoeng habeli ho hlahisa thapo ea PE e habeli ho fetoha thapo e phethiloeng ea tšepe. Khamphani ea rona e hlahisa thapo e phethiloeng ea tšepe ea galvanized, epoxy steel strand e phethiloeng ka thapo le mefuta eohle ea likhoele tsa tšepe tse sa koaeloang, li-suspenders, li-saddles tsa lithapo, likhoele tsa lithapo tsa marokho, joalo-joalo.

Lisebelisoa
Hangata li sebelisoa lits'ebetsong tse hlokang likhoele tse matla le tse tšepahalang, joalo ka lithapo tsa motlakase tse holimo, marokho a emisitsoeng le lits'ebetso tse ling tsa meralo. Likhoele tse tšoanang li thusa ho aba meroalo ka ho lekana, e etsa hore thapo e be e loketseng ho ts'ehetsa meroalo e boima le ho hanela matla a ho kobeha le a torsional.
