Kudzibowola Hollow Nangula
Chiyambi cha Zamalonda
Poyerekeza ndi anangula ena, ubwino wa anangula odzibowola okha ndikuti ndi abwino kugwira ntchito m'madera ovuta omwe kubowola kumakhala kovuta (mwachitsanzo, kusweka, dongo, lotayirira, lopapatiza komanso losweka). Amapereka mayankho okhazikika azamafakitale ofukula pansi komanso othandizira uinjiniya.
Mkati mwa nangula wodzibowolera ndi wopanda kanthu ndipo mulibe zinthu zakuthupi. Mpweya ndi madzi mkati zimatha kuyenda momasuka panthawi yobowola ndikutsuka particles. Pali ulusi wosalekeza kunja umene ungathe kudulidwa pamalo aliwonse. Komanso amabwera ndi kubowola pobowola mabowo. Chifukwa cha mawonekedwe ake, anangula odzibowola okha ali ndi ntchito zambiri. Atha kugwiritsidwa ntchito pakukhazikika kwa ngalande, madamu ndi malo otsetsereka, chitetezo chachitetezo cha avalanche, komanso mapulojekiti othandizira, mapulojekiti othandizira ma radial, kukhazikika kwapakhungu, ntchito zothandizira maziko, ndi misewu. Thandizani mainjiniya ndi ntchito zina zothandizira miyala. Chifukwa nangula palokha ndi dongosolo lapamwamba, masitepe oyikapo ndi osavuta ndipo ntchitoyo ndi yosavuta. Ikhoza kugwira ntchito pansi pa maziko ovuta, monga miyala yofooka, nthaka yotayirira, yosanjikiza nyengo, miyala ya miyala ndi zina zosweka, ndipo imatha kubowola nthawi imodzi. Mabowo, grouting, ndi anangula zimathandizira kwambiri kugwira ntchito. Nangula ndi otchuka padziko lonse lapansi chifukwa cha kuchuluka kwa ntchito komanso kugwiritsa ntchito kwawo m'magawo ambiri.
Ubwino wa Zamalonda
1.Kubowola, kuyika nangula nthawi imodzi (grout imatha kudzaza ming'alu.)
2.Kuyika kosavuta ndi ntchito yosavuta. Kwambiri bwino ntchito bwino.
3.Select zitsulo kubowola malinga ndi mikhalidwe yosiyanasiyana ya pansi.
4.Ikhoza kukulitsidwa pogwiritsa ntchito ma couplers.
5.Zoyenera pazikhalidwe zosweka za geological.
6.Chifukwa chakuti kunja kuli ndi ulusi, kumakhala ndi kupsyinjika kwakukulu kwa mgwirizano kusiyana ndi mapaipi osalala achitsulo.
7.Ili ndi ntchito zambiri ndipo imagwiritsidwa ntchito kwambiri, kuphatikizapo kukhazikika kwa ngalande ndi kulimbikitsa, malo otsetsereka a madamu, chitetezo chachitetezo cha avalanche, zomangamanga zothandizira, ndi zina zotero.
Kuyika Njira
Maboti odzibowola okha nthawi zambiri amayikidwa pogwiritsa ntchito kubowola kozungulira.
Tekinoloje iyi imalola kuyika kwapamwamba, kukhazikika kwamayendedwe abwino, komanso kumathandizira kugwirizanitsa grout mkati mwa borehole.
1.Lumikizani chobowola cha alloy ndi ndodo ya nangula kumalekezero amodzi, gwirizanitsani dzanja la kubowola ndi adaputala kumapeto kwina, kenaka mugwirizanitse chobowola kapena chogwiritsira ntchito pamanja.
Kenako yambani kubowola, kuwonjezera madzi ozizira pobowola. (Ngati mukufuna kukulitsa ndodo ya nangula, mutha kulumikiza cholumikizira ndikubowola mabowo)
2.Chotsani pang'ono pobowola, ikani choyimitsira chotchinga mu ndodo, ndikuchiyika mu dzenje kukonzekera grouting.
3.Lumikizani mgwirizano wa grouting ndi mapeto a nangula, ndikugwirizanitsa mapeto ena a makina opangira.
4.Yambani grouting. Pamene grouting yadzaza ndikufikira mtengo wapangidwe, zimitsani mphamvu.
Kuthamanga kwa grouting kumatsimikiziridwa kutengera magawo a mapangidwe ndi magwiridwe antchito a makina a grouting.
5.Ikani pansi mbale ndi mtedza, ndikumangitsani mtedza.
