Kodi mulu wa dothi la simenti ndi wodalirika ngati njira yothandizira dzenje la maziko?

Khoma la nthaka ya simenti ndi njira yothandizira yosagwiritsidwa ntchito kwambiri, yoyenera nthaka yopapatiza, ndipo sigwiritsidwa ntchito kwambiri mu ntchito zauinjiniya. Makhoma a nthaka ya simenti nthawi zambiri amagwiritsidwa ntchito m'maenje ofewa a nthaka okhala ndi kuya kochepa. Pansi pa izi, ndodo ya nangula ilibe gawo loyenera la nthaka yomangira, lomwe silingapereke mphamvu zokwanira zomangira, ndipo chithandizo chamkati chidzawonjezera zovuta zomangira nyumba yayikulu yapansi panthaka. Pakadali pano, pamene kufananiza kwathunthu kwa ndalama, nthawi yomanga, kuthekera kwaukadaulo, ndi zina zotero kuli bwino kwambiri, makhoma a nthaka ya simenti nthawi zambiri amasankhidwa ngati njira yothandizira. Makhoma a nthaka ya simenti nthawi zambiri amagwiritsa ntchito milu yosakaniza, ndipo zinthu za khoma ndi nthaka ya simenti, yomwe ili ndi mphamvu yochepa yomangirira komanso yodula. Ikapangidwa ndi kapangidwe ka mtengo, magwiridwe antchito ake ndi otsika ndipo sangayerekezedwe ndi zipangizo za simenti. Chifukwa chake, pokhapokha ngati idapangidwa molingana ndi kapangidwe kochokera ku mphamvu yokoka ndi komwe ingakhale ndi zabwino zina.

Pamene makoma osungira simenti akugwiritsidwa ntchito pomanga dothi la matope ndi maziko a matope, kuya kwa dzenjelo sikuyenera kupitirira 7m. Chifukwa cha kapangidwe ka mphamvu yokoka, kukula kwa khoma lalikulu kumafunika. Pamene kuya kwa dzenje la maziko kuli koposa 7m, pamene kuya kwa dzenjelo kukuwonjezeka, m'lifupi ndi kuzama kwa khoma kumakhala kwakukulu kwambiri, zomwe sizili zoyenera pazachuma, malinga ndi ndalama zomangira ndi nthawi yomangira. Kusakwanira kwa khoma kungayambitse kusamuka ndi kukhazikika, pomwe m'lifupi wosakwanira kungayambitse ming'alu kapena kugubuduzika kwa khoma. Ngakhale makoma a nthaka ya simenti okhala ndi milu yosakaniza angagwiritsidwenso ntchito pomanga milu ya maziko m'mitundu ya nthaka monga dothi logwirizana, matope, ndi nthaka yamchenga, nthawi zambiri ndibwino kusankha njira zina zothandizira. Pazochitika zapadera, makoma a nthaka ya simenti okhala ndi milu yosakaniza angagwiritsidwebe ntchito pa mitundu ya nthaka iyi.

Poyerekeza ndi kapangidwe kosungira, pali mavuto ena osathetsedwa kapena kusowa kumvetsetsa kokhwima komanso kogwirizana pakupanga makoma a misomali ya nthaka. Mwachitsanzo, monga kapangidwe kake, palibe njira yokwanira yowunikira kapangidwe ka makoma a misomali ya nthaka, ndipo mavuto a kupsinjika kwa misomali ya nthaka ndi kupsinjika kwa pamwamba pa nthaka pansi pa mikhalidwe yogwirira ntchito sanathetsedwe. Kapangidwe ka pamwamba pa nthaka kangathe kuthetsedwa pokhapokha potsatira zofunikira pa kapangidwe kake. Malamulo oyenerera amafotokoza zofunikira pakupanga pamwamba pa nthaka, koma amangokhudza maenje a maziko omwe alibe nthaka yofewa komanso opanda madzi apansi panthaka mkati mwa kuya kwa 12m. Vuto lowerengera kusamuka kwa makoma a misomali ya nthaka silinathetsedwe kwenikweni. Chifukwa cha kachitidwe kofala ka makoma a misomali ya nthaka ku China, komwe sikugwiritsa ntchito prestress ku misomali ya nthaka, misomali ya nthaka imafika pamlingo wawo wogwirira ntchito pambuyo pa kusintha kwina kwa dzenje la maziko. Chifukwa chake, mwachiphunzitso, kusamuka ndi kukhazikika kwa makoma a misomali ya nthaka ndi kwakukulu. Pakakhala nyumba kapena nyumba zina mkati mwa malo omwe akhudzidwa ndi kusinthaku kuzungulira dzenje la maziko, sikoyenera kugwiritsa ntchito chithandizo cha khoma la misomali ya nthaka.
