Simbi Yakanakisisa Yakagadziriswa Uinjiniya Yakagadziriswa Nesimbi Yakagadziriswa Nesimbi Yakagadziriswa
Tambo yesimbi yakasungirirwa itambo yesimbi yakasungirirwa ine waya dzesimbi mbiri, nhatu, manomwe kana gumi nepfumbamwe dzakasimba, uye yakamborapwa kuderedza kushushikana (kurapwa kwekugadzikana), yakakodzera kongiri yakasungirirwa kana zvimwe zvakafanana.
Hunhu hukuru hwetambo dzesimbi dzakasimbiswa simba rayo rakakwirira, kugona kwayo kugadzikana, uye dzakatwasuka kana dzavhurwa. Simba rekudhonza rakajairika i1860 MPa, uye kune simba remhando dzakadai se1720, 1770, 1960, 2000, uye 2100 MPa. Simba remubereko wesimbi iyi rakakwirawo zvakanyanya.
Chitanda chesimbi chine kabhoni yakawanda chinodhonzwa muwaya yesimbi mushure mekugadzirisa pamusoro, uye ipapo waya dzesimbi dzakawanda dzinomonyororwa kuita tambo zvichienderana nechimiro chetambo yesimbi, uye dzinobva dzagadzirwa kuburikidza nenzira yekuderedza kushushikana. Kuti irambe yakasimba, waya yesimbi inogona kuve nesimbi kana kuti kwete-simbi plating kana coating, senge galvanizing, epoxy coating, nezvimwewo. Kuti iwedzere simba rekubatana nekongiri, pamusoro payo panogona kunge paine nicks nezvimwewo. Tambo yesimbi yakaumbwa prestressed inoitwa maitiro ekumanikidza mold mushure mekusunga, chimiro chacho chakasimba uye chikamu chepamusoro chakakodzera kunamira. Kuti ugadzire tambo dzesimbi dzisina bond (tambo dzesimbi dzisina bond) shandisa tambo dzesimbi dzakajairika dzakaiswa prestressed, dzakaputirwa nemafuta ekudzivirira ngura kana paraffin wax, uye wozoputirwa ne high-density polyethylene (HDPE).
