Kuchitira mphamvu dothi

yomanga kukonzekera kunyumba - ndi ntchito yofunika ndi udindo ndi amene amafuna zinthu zina. Polenga dziko ntchito nyumba ayenera kuganizira zinthu zingapo zimene zingakhudze mayendedwe lonse.

Kodi muyenera kuganizira mu malo oyamba?

Nkofunika kudziwa kuti kutenga mphamvu nthaka ndi khalidwe zofunika kusonyeza mlingo wa maganizo, amene angathe kupirira unit pansi m'deralo. Childs, izo amayezedwa T / m2 kapena makilogalamu / cm2. chizindikiro Zimenezi zimathandiza kudziwa zimene katundu ayenera kuthandizidwa m'dera maziko.

Kawirikawiri anatsimikiza ndi makhalidwe atatu aakulu nthaka zimene zimakhudza katundu mwankhanza mphamvu. Izi machulukitsidwe chinyezi nthaka, compactness ake ndi kalembedwe.

Nthaka zimakhudza mphamvu kwakukulukulu amachepetsa ndi kuwonjezeka chinyezi. Khalanibe zikutsatiridwa okha zimatha kukula mchenga sing'anga. Pa chinyezi owonjezera akhoza kulankhula mkulu mlingo wa pansi. Zikatero, si koyenera kuti amachita chithandizo cha Akatswiriwa, chifukwa chithunzi ichi n'zotheka kudziwa paokha. M'pofunika kukumba mozama dzenje fosholo 2 m (kapena kubowola a osati zitsime zokumba zogwiritsa lapansi borer), ichi chidzakhala chokwanira kudziwa mtundu wa dothi ndi mlingo wa hydration.

Kudziwa mtundu wa dothi akhoza kukhala mu diso. Kuzindikira mchenga sadzakhala zovuta aliyense. Loam yemweyo ali ductile ndi limapangidwa 30% ya particles dongo, dongo mchenga - zinthu zambiri Chimaona ndi silimba mosavuta pansi kuthamanga pang'ono kupereka mtanda, koma dongo nthaka ndi ambiri ductile psinjika inasanduka mkate. Ndi kuchuluka kwa madzi mu dzenje zakale tingadziwire chinyezi m'dziko ndi moyandikana a pansi.

Chichitiranso mphamvu zikuphatikizapo zizindikiro za osalimba nthaka. Komabe, phindu izi zikhoza kukhala zonse. Pa inali kwambiri wosanjikiza mobisa nthaka kukakamizidwa zigawo zina pamwamba Komabe, pamene kuchotsedwa pamwamba chake chochuluka kachulukidwe kwambiri m'munsi. Choncho, kuwerengetsa kutenga mphamvu, izo zikhoza kuganiziridwa pansi wandiweyani pokhapokha ngati malo pa akuya 0.8-1 m.

Tikumbukenso kuti si nthawi zonse maphunziro yoyenera mulili, wosalira anapezazo, iwo amaganiza kuti kutenga mphamvu nthaka ndi wofanana 2 kg / cm2.

Komabe, pokonzekera kumanga nthaka si nthawi zonse limafanana ndi magawo amene akufunika kukhazikitsidwa kwa maziko mogwirizana ndi ntchito yomanga. umisiri wamakono zathandiza zimakhudza khalidwe la nthaka, kotero pali matekinoloje amene atenga mbali yake.

Kutukula basi ayenera kuchita miyeso kuti kuonetsetsa chitetezo ndi kulimbitsa dothi. Chitetezo choyamba chofunika kuteteza mphepo, madzi ndi makina kukokoloka.

Kulimbikitsa nthaka pali njira zingapo wamba mwachitsanzo, kuwonjezera katundu makina, yomwe ikuchitika ndi kukhazikitsa zinthu mwapadera mu dongosolo nthaka (otchedwa zolimba). N'zothekanso kuchita mankhwala kulimbikitsa nthaka, amene analandira mwa akatembenuka iwo unatha mankhwala ndi reagents mankhwala. Ntchito binders monga phula, phula, simenti organic ndi zochita kupanga zinyansi kumathandiza kulimbikitsa nthaka.

Nkofunika kuzindikira kuti pambuyo yomanga nyumba watha, chifukwa angayambitse iye shrinkage, tizivutika ndi dongosolo lonse ndi subsidence wa maziko. akatundu m'goli ndi zambiri chifukwa cha ming'alu, amene kenako kumabweretsa chiwonongeko cha nyumba lonse. Osati nthawi zonse otsika zimakhudza mphamvu nthaka ndiye chifukwa chachikulu zimene zingachititse kuti mavuto amenewa. Komabe, kuti kusankha bwino mtundu wa maziko, ayenera n'komwe mu malo oyamba.
