Mwachidule za Anchor Hollow Steel Bars
Mipiringidzo yachitsulo ya nangula imapangidwa m'magawo okhala ndi kutalika kwa 2.0, 3.0 kapena 4.0 m. The awiri akunja awiri mipiringidzo dzenje zitsulo ranges kuchokera 30.0 mm kuti 127.0 mm. Ngati ndi kotheka, mipiringidzo yachitsulo yopanda kanthu imapitilizidwa ndi kugwirizana kwa mtedza. Mitundu yosiyanasiyana ya ma kubowola nsembe imagwiritsidwa ntchito kutengera mtundu wa dothi kapena miyala. Chitsulo chopanda dzenje ndi chabwino kuposa cholimba chokhala ndi malo opingasa omwewo chifukwa cha kapangidwe kake kabwinoko potengera kulimba, kuzungulira ndi kuuma kopindika. Chotsatira chake ndi kukhazikika kwapamwamba komanso kusinthasintha kwachitsulo chofanana ndi chitsulo.

Mapulogalamu a Self Drilling Anchor Rods
M'zaka zaposachedwa, pakuwonjezeka kwa kufunikira kwa chithandizo cha geotechnical, zida zoboola zakhala zikusinthidwa ndikupangidwa. Panthaŵi imodzimodziyo, ndalama zogwirira ntchito ndi zobwereka zakwera, ndipo zofunika panthaŵi yomanga zakwera kwambiri. Kuphatikiza apo, kugwiritsa ntchito ndodo zodzibowolera zopanda pake m'malo omwe amatha kugwa kumakhala ndi zotsatira zabwino kwambiri. Zifukwa izi zapangitsa kuti kuchulukirachulukira kogwiritsa ntchito ndodo zodzibowolera zokha. Zodzibowolera zokha za nangula zimagwiritsidwa ntchito makamaka pazifukwa izi:
1. Amagwiritsidwa ntchito ngati ndodo ya nangula yokhazikika: imagwiritsidwa ntchito ngati malo otsetsereka, kukumba pansi, ndi anti zoyandama kuti zilowe m'malo mwa zingwe za nangula. Ndodo za nangula zodzibowolera zokha zimabowoleredwa mpaka pakuya kofunikira, ndiyeno kumapeto kwa grouting kumachitika. Pambuyo pa kulimbitsa, kupanikizika kumagwiritsidwa ntchito;
2. Amagwiritsidwa ntchito ngati ma micropiles: Ndodo za nangula zodzibowola zokha zimatha kubowoledwa ndi kugwetsedwa pansi kuti zipange ma micropiles, omwe amagwiritsidwa ntchito kwambiri pamaziko a nsanja yamphamvu yamphepo, maziko a nsanja yotumizira, maziko omanga, kusunga maziko a milu ya khoma, maziko a milu ya mlatho, ndi zina;
3. Amagwiritsidwa ntchito ngati misomali ya dothi: amagwiritsidwa ntchito pothandizira potsetsereka, m'malo mwa ndodo zachitsulo zachitsulo, ndipo angagwiritsidwenso ntchito ngati maziko a dzenje lakuya lothandizira potsetsereka;
4. Amagwiritsidwa ntchito popangira misomali ya mwala: M'malo otsetsereka kapena ngalande zokhala ndi nyengo yoipa kwambiri kapena yotukuka molumikizana, ndodo zodzibowolera zokha zimatha kugwiritsidwa ntchito pobowola ndi kuphatikizira kulumikiza midadada kuti ikhale yokhazikika. Mwachitsanzo, mapiri otsetsereka a misewu ikuluikulu ndi njanji amene amatha kugwa akhoza kulimbitsidwa, ndipo mipope wamba ingasinthidwenso kaamba ka kulimbikitsa pamipata yotakasuka;
5. Kulimbikitsa kapena kuyang'anira masoka. Pamene nthawi yothandizira ya dongosolo lothandizira la geotechnical loyambirira likuwonjezeka, zida zothandizirazi zimatha kukumana ndi mavuto omwe amafunikira kulimbikitsidwa kapena chithandizo, monga kusintha kwa malo otsetsereka oyambirira, kukhazikika kwa maziko oyambirira, ndi kukweza pamwamba pa msewu. Ndodo zodzibowolera zokha zingagwiritsidwe ntchito pobowolera pamalo otsetsereka, maziko, kapena msewu, ndi zina zotero, pobowola ndi kuphatikiza ming'alu, kuteteza kuti masoka achilengedwe asachitike.
