Chidule cha R25 Self-Drilling Hollow Grout Injection Anchor Rod
Ndodo zomangira nthawi zambiri zimakhala zoyenera kulimbitsa chithandizo m'matanthwe a migodi, m'matanthwe a mlatho, m'malo otsetsereka, ndi m'malo ena. Kawirikawiri, mabowo a ndodo zomangira amabowoledwa pogwiritsa ntchito chobowolera ndodo, ndipo zomangira zoyenera (mipukutu ya ufa wa resin) zimayikidwa. Kenako, zida monga chobowolera ndodo zomangira zimagwiritsidwa ntchito kubowolera ndodo yomangira m'dzenje la ndodo zomangira, kusakaniza ndi kumangirira chomangira, kenako kugwiritsa ntchito zida monga chobowolera ndodo zomangira kuti ziyike mtedza pamenepo; Ndodo yomangira yamanja, yomwe imadziwikanso kuti ndodo yomangira yachitsulo yofanana ndi chitsulo, imapangidwa ndi chitsulo chopindidwa chamanja (kapena kumanzere), chokhala ndi ulusi wopitilira komanso kutalika konse komwe kumatha kulumikizidwa ndi mtedza. Imagwiritsidwa ntchito limodzi ndi mtedza wa mbale zomangira kuti ithandizire ngalande. Bolt ndi chinthu cholowa m'malo mwa bolt yolimbana ndi mtanda wokazinga, yokhala ndi magwiridwe antchito abwino kwambiri.

Zinthu zomwe zimagwiritsa ntchito ndodo yodzibowolera yokha yopanda kanthu yopangira grouting
1. Yotetezeka, yodalirika, komanso yosunga nthawi.
2. Kukhazikitsa kosavuta ndi ntchito.
3. Kusankha ma drill bits osiyanasiyana pa nthaka.
4. Ntchito zogwirira ntchito zimagwirizanitsidwa ndi kuboola kapena pambuyo poboola. Grout imatha kudzaza bwino mabala.
5. Mipiringidzo ya nangula imatha kudulidwa ndikukulitsidwa ngati ipemphedwa, pogwiritsa ntchito malo opapatiza.
6. Imapereka mphamvu yolimba kwambiri kuposa chitoliro chosalala chachitsulo kutengera ulusi wopitilira wa mafunde.
Ubwino wa kubowola nokha ndi ndodo ya nangula yopanda kanthu
1. Ndodo ya nangula yoboola yokha yokhala ndi dzenje imagwiritsa ntchito chitoliro chachitsulo cholimba chopanda msoko, njira yofulumira yopangira ulusi pamwamba, ndi zowonjezera zokongola, zomwe zimapangitsa kuti ntchito ya nangula yoboola yokha ikhale yofanana ndi kuboola, kulumikiza, kulumikiza ndi zina.
2. Pali chobowola chomwe chili ndi mphamvu yolowera patsogolo pa ndodo yodzipangira yokha yopanda kanthu, yomwe imatha kulowa mosavuta m'mitundu yosiyanasiyana ya miyala pogwiritsa ntchito makina obowola miyala wamba.
3. Ili ndi ulusi wokhazikika wa mafunde ndipo ingagwiritsidwe ntchito ngati ndodo yobowolera kuti imalize kubowola mabowo okhazikika pogwiritsa ntchito chobowolera.
4. Thupi la ndodo yolumikizira ya chitoliro chobowolera siliyenera kuchotsedwa, ndipo malo opanda kanthuwo akhoza kukhala njira yolumikizira grouting kuchokera mkati kupita kunja.
5. Choyimitsa grouting chingathe kusunga mphamvu ya grouting, kudzaza mipata yonse, kukonza miyala yosweka, ndipo mapepala ndi mtedza wamphamvu zimatha kusamutsa mofanana mphamvu ya thanthwe lozungulira kupita ku thanthwe lozungulira, kukwaniritsa cholinga chothandizana pakati pa thanthwe lozungulira ndi ndodo ya nangula.
6. Chifukwa cha ntchito ya ndodo ya nangula yamtunduwu, imatha kupanga mabowo a nangula ndikuwonetsetsa kuti imagwira ntchito bwino popanda kugwiritsa ntchito njira zapadera monga kuteteza khoma ndi kuyika makoma pa nthawi yomanga pansi pa miyala yosiyanasiyana.
