Miyero yekugamuchirwa uye zvimiro zve centrifugal kongiri murwi kudzvanya

Ngatidzidzei pamusoro pekugamuchirwa kwemitemo uye tsika centrifugal kongiri murwi kudzvanya kuburikidza nechinyorwa chinotevera cheQuatest. 

Chii chinonzi centrifugal concrete pile?

Pfungwa ye centrifugal kongiri mirwi 

Centrifugal kongiri mirwi ikongiri mirwi isingashandisi simbi nesimbi, yakaboora mirwi semirwi. aerated powder kazhinji. Mhando iyi yemurwi inoshandisa tekinoroji yemazuva ano yekugadzirisa. Chikamu chepasi pevhu chakagadzirwa nehukuru hwekutakura. Naizvozvo, hunyanzvi hwemhando yepamusoro hunogona kuvimbiswa mune yakawanda yeiyo chaiyo nzira yekuvaka.

Zvimwe kunze kwe kongiri mbiruMurwi weCentrifugal une chimiro chedenderedzwa, inodururwa ne centrifugal rotation method, inoiswa mubhailer patembiricha ingangoita 96 degrees Celsius. 

Sei mirwi yekongiri yecentrifugal ichishandiswa zvakanyanya? 

Nekuenderera mberi kwekuvandudzwa kwenzvimbo dzemumaguta, huwandu hwevanhu vari kuuya pano huri kuwedzera zuva nezuva. Zvinokonzera kuwedzera nguva dzose kwekuda kweimba. Naizvozvo, tekinoroji yekugadzirisa yakasimbiswa kongiri rusvingo yakagadziridzwa uye yakasimudzirwa kuti isangane nechido ichocho. Nekuda kwekuva nezvinhu zvakawanda zvakanaka, inokunda zvimwe zvigadzirwa zvekongiri. Asi centrifugal kongiri mirwi inosarudzwa nevanhu vazhinji. Inounza chivakwa chakasimba uye chakasimba nenguva, isinganyanyi kukanganiswa nemamiriro ekunze uye mamiriro ekunze.

Kurongwa kwe centrifugal kongiri mirwi

Nemhando uye kodhi yechigadzirwa

Zvichienderana nerudzi uye kodhi yechigadzirwa, centrifugal kongiri mirwi yakakamurwa kuita maviri marudzi: 

  • Normal prestressed kongiri (PC) murwi: imhando ye prestressed kongiri murwi inogadzirwa ne centrifugal kuruka nzira. Kuva nesimba rekumanikidza kongiri kwete pasi peB40.
  • Prestressed kongiri mirwi yesimba guru (PHC) uye (NPH): ari prestressed centrifugal kongiri mirwi inogadzirwa ne centrifugal kutenderera nzira. Kuva nesimba rekumanikidza rekongiri risiri pasi peB602. 

Zvinoenderana neiyo mechanical quality criteria

  • Classification inoenderana nekukosha kwekupwanya kukotama nguva: Normal prestressed kongiri (PC) mirwi yakakamurwa kuva 4 mhando mitoro: A, AB, B, C. umo, mutoro giredhi A ane kukotama nguva, kwete pasi pe24.5 kN.m. Rodha kirasi AB ine kuputika kwekukotama nguva, isingasviki makumi matatu kN.m. Pamutoro wekirasi B, kukosha uku i30kN.m, ukuwo nhanho yekutakura C iri 34.3kN.m.

Kurongeka zvinoenderana nekukosha kweiyo nguva yekukotama, iyo prestressed kongiri mirwi inowanzo kupatsanurwa kuita 4 mitoro mazinga.
  • Classification zvinoenderana neyakaverengerwa inoshanda kushushikana kukosha, crack bending nguva uye jecha simba:

High-simba pre-yakasimbiswa kongiri mirwi (PHC) yakakamurwa kuita makirasi mana ekutakura: A, AB, B, uye C.
