Sandy loam nthaka - ndichiyani?

Aliyense amene wayamba kumanga nyumba yake, anakumana ndi nkhani ngati kukweza kapena kusalaza dziko mu gawo popanga mapulani. Mchenga ntchito zolinga zimenezi ndi mtengo. Ndipo thandizo akubwera Sandground, kapena (dzina wachiwiri) mchenga loam. Kodi zimakhala ndi kumene ntchito, kutchereza.

tanthauzo

Sandy loam (Sandground) - thanthwe ntchito pomanga ndi zikuchokera kumatanthauza. Kuyambira mutu zikuonekeratu kuti ichi ndi chinachake pafupi ndi mchenga. Ndipotu zikuchokera, kuwonjezera pa particles mchenga, dongo, kuphatikizapo particles kwambiri fumbi.

Lili pakati pa mchenga ndi dongo, yodziwika ndi mphamvu otsika akatundu, poyerekeza ndi yamasika, mchenga loam. Ndi chiyani icho? Monga ntchito olimba nthaka Sikuti. Kusankhidwa ake pa malo zambiri.

Kufotokozera ndi katundu

Kaya malo yopanga ndi anayambira, mchenga loam malinga ndi malamulo a mfundo GOST anawagawa:

• lolemera mchenga loam, dongo zili peresenti 10;
• содержание глины маленькое. kuwala mchenga loam - dongo zili pang'ono.

Mchere zikuchokera thanthwe:

• khwatsi;
• kaolin wa dongo;
• montmorillonite dongo.

Chifukwa kukhalapo mu zikuchokera mchenga ndi particles lalikulu, ndi mikangano koyefishienti ukuwonjezeka. Mwa kaphatikizidwe dongo ndi mchenga, mchenga loam ali ndi makhalidwe awa: friability wabwino ndi otsika dustiness. Chofunika pamene kukhetsa zithaphwi, amaika mumsewu misewu akumidzi. Iwo adzateteza m'misewu ku chiwonongeko.

Pamene kuthira maziko kwenikweni ayenera kuganizira zikuchokera kwa nthaka, ndipo ngati anapezeka mchenga loam (icho chiri, ife kale asanaganize), nthaka ayenera kulimbikitsidwa, ngati mukufuna kukonza wodalirika komanso amphamvu dongosolo.

ntchito

M'dera yaikulu ntchito mchenga loam - yomanga. Malo oipa, chinthu zomangamanga, kuika msewu watsopano. Onse malo awa amafuna zinthu zomanga mchenga loam. Kodi ndi chifukwa inu simungakhoze ntchito mchenga? Inde, monga chuma ndi zambiri zodula. Ndipo m'pofunika kutseka dzenje - ndipo ichi sitingathe kuchita popanda Sandground. Ngakhale mtengo loams m'munsi si abwino Mwaichi chifukwa cha ductility ake okwezeka.

Kamangidwe malo owazidwa mchenga njira loam munda. Nthawi yomweyo dongosolo ngalande. Ndipo m'nyengo yozizira kuposa m'mabande n'kuwaza pa ayezi? Kumene, Sandground.

Pa malo, kumene nyumba, nthaka anali loamy. Kusoŵanso mchenga loam. Kodi ndi chifukwa popanda sitingapeze chiyani? Ndipo onse chifukwa cha loam, mkulu ductility ndipo patapita nthawi, anayerekezera zimene zingachititse kuti akulimbana kapena chiwonongeko cha nyumba maziko. Sandy loam nthaka chabe m'munsi ductility, kupanga yabwino kwambiri, ndipo kuchepetsa ndondomeko shrinkage.

Phula osakaniza si kuchitidwa popanda Sandground. Agwirizane nazo ndi dothi. Iwo kuyika mu njira marshland - yekha ntchito mtundu uwu ntchito njira ndi kumanga siyabwino loam ndi mchenga misewu.

Kupanga zomangira: ziwiya zadothi, njerwa, midadada - Gwiritsani ntchito yathu "ziphona".

m'zigawo

Field, kumene umabala mchenga loam, amapezeka mwapadera dera lonse la Chitaganya cha Russia. котлованный песок. Popeza kuti ncho mu quarries, komanso mu ngalande ndi maenje (danga lotseguka izi zonse), n'zotheka kupeza dzina lina la thanthwe ili - maziko mchenga dzenje. Mwamvetsa izo ndi pamene yomanga kumangira nyumba Mipikisano storey, kupitiriza ntchito pa malo omwewo.

Pomanga chinthu pa yapafupi mchenga loam gawo kutenga, monga kuzibweretsa izo ku dera lina, kuziyika izo modekha, ndi opanda pake. madipoziti mafakitale-mtundu zopezeka mu gawo ambiri European la Russia ndi Karelia zinthu ncho m'zigwa mtsinje, ngakhale palinso chisanadze glacial madipoziti.

Zikuonekeratu kuti popanda loam mchenga sachita nyumba, kaya ndi nyumba kapena njira. Ndi mtengo kwambiri kuposa mchenga zomwe mupeze oipa ogulitsa. Pogula amamvetsera miyala, amene anabweretsa. песок должен тут же рассыпаться, ведь в его составе не содержатся алевритовые частицы, которые и отвечают за слипание породы. Kudziwa ichi loam mchenga kapena mchenga, pogwiritsa ntchito njira zotsatirazi: madzi anabweretsa mwala wawung'ono ndi mayina, yeserani - mchenga ayenera yomweyo usathe, chifukwa kapangidwe kake lilibe matope particles, amene ali ndi udindo kukakamira zimasokoneza. Koma Sandground ali ndi mpira akhoza adagulung'undisa za izo. Khalani maso, ndipo ntchito yomanga idzachitike molondola.
