Mwachidule za nangula yopanda chitsulo
Mabatani a nangula snow amapangidwa m'magawo okhala ndi kutalika kwa 2.0, 3.0 kapena 4.0 m. Ma diamer kunja kwa chitsulo chofewa chimachokera ku 30,0 mm mpaka 127.0 mm. Ngati ndi kotheka, mabatani achitsulo amapitilira ndi mtedza wophatikizira. Mitundu yosiyanasiyana ya ma bits operekera ndalama amagwiritsidwa ntchito kutengera mtundu wa nthaka kapena rock misa. Mbali yachitsulo ndiyabwino kuposa malo okhazikika okhala ndi gawo lomweli ndi gawo lomwelo chifukwa cha mayendedwe ake abwino malinga ndi momwe amagwirira ntchito, kuzungulira ndikugwada. Zotsatira zake ndi chokhazikika kwambiri komanso chosasinthika cha zitsulo zofanana.

Ntchito zodzikongoletsera za mangu
M'zaka zaposachedwa, ndikuwonjezereka kwa geotechnical thandizo, zida zobowola zasinthidwa nthawi zonse ndikupangidwa. Nthawi yomweyo, ndalama zobwereka komanso zobwereka zachulukirachulukira, ndipo zofuna za nthawi yomanga zakhala zokulirapo. Kuphatikiza apo, kugwiritsa ntchito mabowo owongoletsera obowola kwambiri m'mikhalidwe ya geological yomwe imatha kugwa ili ndi zotsatira zabwino kwambiri. Zifukwazi zapangitsa kuti anthu omwe afalikira ofala omwe amafalikira okha ndi ndodo. Ndodo zakukhosi zakufalikira zimagwiritsidwa ntchito makamaka pazotsatira zotsatirazi:
1. Zogwiritsidwa ntchito ngati anchor ndodo: zomwe zimagwiritsidwa ntchito pazochitika monga malo otsetsereka, mobisa, komanso anti oyandama kuti asinthe zingwe za Anchor. Ndodo zakukhosi zakufalikira zimakokedwa kuzama, kenako ndikuthetsa. Pambuyo polimba, kusamvana kumayikidwa;
2. Zogwiritsidwa ntchito ngati microples:
3.
4. Ntchito misomali yamiyala: M'miyala inayake yotsetsereka kapena zophatikizira zokhala ndi nyengo, kudziletsa ndodo zobowola zitha kugwiritsidwa ntchito pobowola ndi kuwomba rod mithunzi ya bonganani kuti musinthe. Mwachitsanzo, misewu yotsetsereka ya misewu yayikulu ndi njanji zomwe zimawonongeka zimatha kugwa, ndipo ma shedi achilendo amatha kusinthidwa kuti alimbikitsidwe m'malo otsegulira;
5. Kulimbikitsidwa kapena kuwongolera tsoka. Pamene nthawi yothandizira kwa geotechnical yoyambirira ikuwonjezeka, mapangidwe ena amenewa amakumana ndi mavuto ena omwe amafunikiranso kulimbikitsa kapena chithandizo, monga kuphatikizika kwa malo oyambira, kukhazikika kwa maziko, ndikuwongolera pamsewu. Ndodo zakukhosi zobowoleza zikuluzikulu zitha kugwiritsidwa ntchito poyenda mmalo oyambira, maziko, kapena msewu wamsewu, etc., chifukwa chopukutira ndi kuphatikiza kupezeka kwa masoka.
