Kuthirira madzi ndi kumeza mbali za nyumbayo. Mitundu ya madzi osokoneza bongo malinga ndi njira yogwiritsira ntchito ndi mfundo yochita. Akatswiri.
Chifukwa chopangidwira masitima a nyumba za nyumba ndizofanana ndi m'mapanga achilengedwe, kutayikira komwe kumayambitsa.
Magawo ofuna kukonzanso zokutira:
a) kuvula pansi burashi wachitsulo;
b) kubweretsa burashi ku zitsulo zazitsulo za kema armafix anticrossion yophimba;
c) Kuyika wosanjikiza wa fai fm (3 mm);
d) Kubwezeretsa kwa wotchinga konkriti pogwiritsa ntchito chosakaniza chowuma cha fai rm.
Mphepo yamtunduwu siyimangoteteza pansi m'madzi, komanso kupulumutsidwa ku ozizira.
Madzi ndiye maziko a moyo, wopanda iyo, munthu sadzatha masiku asanu. Komabe, mawonekedwe a chinyezi mu chipinda chapansi sikuti amangowononga mwiniwake wa momwe akumvera, komanso poimba moyo uno.
Za makumi ambiri zomangidwa m'zaka zaposachedwa (ndipo nthawi zambiri zimakhala zokwera mtengo kwambiri), anthu ambiri amafunikira kukonza kwakukulu ndi malo okhala pansi. Kuphatikiza apo, kukonza kumeneku sikukumveka popanda kubwezeretsanso dongosolo lonse la madzi osautsa maziko ndi mbali zomenyedwa za nyumbayo. Chifukwa cha kutayikira kwa "mliri" chonchi - mu zolakwa za kapangidwe ka kapangidwe kake, chifukwa chosowa kapena omanga kwambiri, ntchito yabwino kwambiri, ndipo nthawi zina zimakhala zosangalatsa kwambiri wopanga.
Mitsinje yapansi panthaka, malo ogulitsira
Mulingo wapansi panthaka (agb) zimatengera mtundu wanthaka. Mwachitsanzo, kuti ku Moscow dera ndi kozungulira. Imasiyanitsidwa ndi kufooka kwamadzi ndi kuzama kwa bomba lomwe limaphulika kwa aqufar. Kukongola kwa malo obisika pansi kumakakamizidwa kuthana ndi kafukufuku wa hydrogelogical. Ngati cholepheretsa china chake chidzakhala pamalo okweza (mwachitsanzo, maziko a konkriti a nyumba yanu), magwero oyenda pansi pa nyumba amatsuka. Kusungunuka kwa chipale chofewa ndi madzi oundana, mvula yachilimwe, Mtima wolumula wa ndakatulo, - zonsezi zimayambitsa zowonjezera kusefukira kwa nyumbayo.Mawonekedwe a dothi "m'lifupi =" okhazikika
Kwina kumeneko, mwa kuya, pali dothi lotentha. Kuchokera pamenepo, chinyezi chimakwera dothi lonse mu digiri imodzi kapena ina ndi madzi osokoneza bongo ndipo, monga zinthu zilizonse zopweteka, kuyesera kuti mudzitengere madzi palokha. Dothi lodzaza kwambiri ndi lowonda la ma pores mmenemo, kukwera kwa ma capillar kumadzi. Ngakhale dongo lonenepa kwambiri ndilochedwa kwambiri, koma limaphulika chinyezi kutalika kwa 12 m ndi kuposa momwe alfande.

Mazikowo akukhala nthawi yomweyo ndikuletsa (nthabwala)
Mtengo wamaziko nthawi zambiri umakhala 15-20% ya mtengo wathunthu wa nyumbayo, ndipo mtengo wa madzi ndi 1-3%. Koma zolakwika ndi magwiridwe antchito osauka sizingafunike kugulitsa mtsogolo mwa mtsogolo.Chifukwa chake, ntchito yomanga imayamba ndi malo osungiramo maziko. Maziko omwe amaperekedwa kwambiri amakhala ndi zabwino zambiri, zomwe zimapezeka kwambiri komanso njira yabwino yopezera ndalama. Koma kuchokera pakuwona kwa madzi oteteza madzi ndiofunika mpaka maziko a monolitic. Kusowa kwa ma seams otsika kumathetsa kufunika kopita panjira yawo, ndiye kuti, kudzazidwa ndi matope a simenti. Kuphonya pang'ono kolumikizana (komwe kuli ochepa, monga lamulo, ma brigades omanga kuchokera kum'mwera kuchokera kumphepete mwa nyanja) kwa mzere wapakatiwo sikokwanira.
Palibe ntchito yomanga popanda kuphwanya (chitsanzo, nsanja yotchuka mu mzinda wa Pizi, Italy). Zosakhazikika za nthaka, risiti ya chinyezi cha nyengo, kutentha kumayambitsa dziko lapansi ndipo, mavuto amkati mwa chipinda chapansi. Chinyezi chomwe chimatenga mu pores of konkriti chikukula nthawi yozizira (ndi 9%) ndikuphwanya. Chifukwa chake microwracks imapangidwa, kutsegula njira yopita kwa madzi omwe amagwira. Vutoli silinayambika lero, ndi njira ya chilolezo wake pali ambiri.
Malinga ndi njira yogwiritsira ntchito ndi mfundo yogwirira ntchito, mitundu yotsatirayi ya kusaina kwamadzi imadziwika bwino: Kukuta, kulowa, kulowa, kuyika.
Kuphatikiza apo, pali: nyimbo zokhazikika zokonza zokolola zadzidzidzi; Ukhondo; Nyimbo za Hydrophobic zopereka konkriti ndi njerwa zodzikongoletsera; Antisole, odana ndi vuto lalikulu komanso kuchuluka kwambiri.
Zopusa zamadzi
Zaka 5000 zapitazo, nzika zakale pomanga nyumba mu lotastone zinagwiritsa ntchito phula lachilengedwe kuti lizikhala ndi madzi. Ndipo tsopano, zinthu zomveka ndi zida zopindika ndizofala kwambiri, zodziwika, ndizotsika mtengo, zotsika mtengo, zosavuta kugwiritsa ntchito. Koma ziyenera kukumbukiridwa m'maganizo mwa izi: moyo wawo wautumiki umangokhala zaka zisanu kapena zisanu ndi chimodzi. Chowonadi ndichakuti phula lokha limataya kale ndipo limakhala losalimba kale pa 0 ° C ndikukula pa kutentha kozungulira kumeneku kumayambitsa mawonekedwe a ming'alu. Kuphimba kumeneku kumakhala kapena kufinya. Kuphatikiza apo, kugwira ntchito yotentha kwambiri (kutentha kutentha (kutentha kutentha mukagwiritsa ntchito 120 ° C!) Ndizosasangalatsa komanso zowopsa.
Kusekula kwa zinthu za Petrochetum kumadzetsa kutuluka kwa omwe akupikisana nawo kwambiri, zitsulo zopangidwa (ma polima) ndi zida zozikika pa iwo. Bitumen-rabara ndi phula-polymeric mass ozizira ozizira pa zosungunulira organic zimapangidwanso.
