Chidule cha Anchor Hollow Steel Bars
Mipiringidzo yachitsulo yopanda kanthu imapangidwa m'magawo okhala ndi kutalika koyenera kwa 2.0, 3.0 kapena 4.0 m. M'mimba mwake wakunja wa mipiringidzo yachitsulo yopanda kanthu imakhala pakati pa 30.0 mm mpaka 127.0 mm. Ngati kuli kofunikira, mipiringidzo yachitsulo yopanda kanthu imapitilizidwa ndi mtedza wolumikizira. Mitundu yosiyanasiyana ya zidutswa zobowolera zodzipereka imagwiritsidwa ntchito kutengera mtundu wa dothi kapena miyala. Mpiringidzo wachitsulo wopanda kanthu ndi wabwino kuposa mpiringidzo wolimba wokhala ndi gawo lomwelo chifukwa cha kapangidwe kake kabwino pankhani ya kugwedezeka, kuzungulira ndi kulimba kopindika. Zotsatira zake zimakhala kugwedezeka kwakukulu komanso kukhazikika kwa chitsulo chofanana.

Kugwiritsa Ntchito Ndodo Zodzibowolera Zokha
M'zaka zaposachedwapa, chifukwa cha kufunikira kwakukulu kwa thandizo la zaumisiri, zida zobowola zakhala zikusinthidwa nthawi zonse ndikupangidwa. Nthawi yomweyo, ndalama zogwirira ntchito ndi zobwereka zawonjezeka, ndipo zofunikira pa nthawi yomanga zakwera kwambiri. Kuphatikiza apo, kugwiritsa ntchito ndodo zobowola zopanda kanthu m'malo omwe amatha kugwa kuli ndi zotsatira zabwino kwambiri zomangira. Zifukwa izi zapangitsa kuti ndodo zobowola zopanda kanthu zigwiritsidwe ntchito kwambiri. Ndodo zobowola zopanda kanthu zimagwiritsidwa ntchito kwambiri m'zochitika zotsatirazi:
1. Amagwiritsidwa ntchito ngati ndodo ya nangula yolimbikitsidwa: amagwiritsidwa ntchito m'malo monga malo otsetsereka, kufukula pansi pa nthaka, komanso osayandama kuti alowe m'malo mwa zingwe za nangula. Ndodo za nangula zopanda kanthu zimabowoledwa mpaka kuzama kofunikira, kenako grouting yomaliza imachitika. Pambuyo polimba, mphamvu imayikidwa;
2. Amagwiritsidwa ntchito ngati ma micropiles: Ndodo zodzibowolera zokha zitha kubooledwa ndikudulidwa pansi kuti zipange ma micropiles, omwe amagwiritsidwa ntchito kwambiri pamaziko a nsanja yamagetsi ya mphepo, maziko a nsanja yotumizira, maziko omangira, maziko osungira makoma, maziko a milu ya mlatho, ndi zina zotero;
3. Amagwiritsidwa ntchito pa misomali ya nthaka: amagwiritsidwa ntchito kwambiri pothandizira malo otsetsereka, m'malo mwa ndodo zachitsulo zokhazikika, ndipo angagwiritsidwenso ntchito pothandizira malo otsetsereka otsetsereka a pansi;
4. Amagwiritsidwa ntchito pa misomali ya miyala: M'malo ena otsetsereka a miyala kapena ma tunnel omwe ali ndi vuto lalikulu pamwamba kapena mapangidwe olumikizana, ndodo zodzibowolera zokha zingagwiritsidwe ntchito pobowola ndi kulumikiza miyala kuti zigwirizane kuti zikhale zolimba. Mwachitsanzo, malo otsetsereka a miyala a misewu ikuluikulu ndi njanji omwe amatha kugwa akhoza kuwonjezeredwa, ndipo ma shed a mapaipi wamba amathanso kusinthidwa kuti agwiritsidwe ntchito polimbitsa ma tunnel otayirira;
5. Kulimbitsa koyambira kapena kuyang'anira masoka. Pamene nthawi yothandizira dongosolo loyambirira lothandizira za geotechnical ikuwonjezeka, zomangamanga zothandizirazi zingakumane ndi mavuto ena omwe amafunikira kulimbitsa kapena kukonza, monga kusintha kwa mtunda woyambirira, kukhazikika kwa maziko oyamba, ndi kukweza pamwamba pa msewu. Ndodo zodzibowolera zokha zingagwiritsidwe ntchito kuboola mtunda woyambirira, maziko, kapena nthaka ya msewu, ndi zina zotero, pobowola ndi kulumikiza ming'alu, kuti zisachitike masoka achilengedwe.
