Mavuto Wamba Ndi Mayankho Amtundu Wa Pervious Konkire

1. Kusakwanira mphamvu ya Mtundu pervious konkire

Mphamvu ya konkire yowonongeka imakhudzidwa ndi zinthu zambiri, makamaka kuphatikizapo: kusakwanira kwa simenti yowonjezera, mphamvu ya miyala yosakwanira, luso lokonzekera, luso lothandizira la SiO2 losakwanira, komanso kusamalidwa kosasintha. Chifukwa chake, ziyenera kuyambira pakukhathamiritsa zopangira, ndikuwonjezera zowonjezera zamchere zamchere ndi kulimbikitsanso organic Zinthu zitatu kuti muwonjezere mphamvu ya konkriti yokhazikika.

2. Mtundu pervious konkire akulimbana

Chifukwa cha kusintha kwa kutentha ndi chinyezi, brittleness ndi kusagwirizana kwa konkire, ndi mawonekedwe osayenerera, ming'alu imawonekera mu konkire yowonongeka itatha kugwiritsidwa ntchito kwa nthawi, kuchititsa mutu kwa ambiri ogwira ntchito yomanga. Choncho, popanga kuphatikiza, chidwi chiyenera kulipidwa kuchepetsa kumwa madzi ndikuwonetsetsa kuti konkire yowonongeka ikugwira ntchito bwino. Khazikitsani ma reinforcements obisika m'mbali zong'ambika mosavuta kuti muwonjezere chiwongolero cholimbikitsira komanso mphamvu yomaliza ya konkriti. M'mapangidwe apangidwe, mawonekedwe a nyengo panthawi yomanga ayenera kuganiziridwa bwino ndipo zogwirizanitsa pambuyo pothira ziyenera kukhazikitsidwa moyenera. Kuwongolera mosamalitsa miyezo yaukadaulo ndiukadaulo wa zida zopangira konkriti, gwiritsani ntchito simenti yotentha ya hydration, ndikuchepetsa matope amagulu owoneka bwino komanso owoneka bwino momwe mungathere (pansi pa 1 mpaka 1.5%).

3. Pinholes kapena thovu kuonekera pa Mtundu pervious konkire

Chifukwa chachikulu cha mapangidwe a pinholes ambiri amtundu wa pervious konkire ndi chakuti zosungunulira mu penti permeable pansi penti adamulowetsa pambuyo kujambula, kusiya utoto madzi mochedwa kudzaza, kuchititsa mabwalo ang'onoang'ono zozungulira, mabowo kapena pinholes. Konkire yovomerezeka yokhala ndi vanishi yotsika ndi mtundu wa pigment pamtunda wosanjikiza ndizosavuta kuzinthu izi.

4. Miyala yocheperako ikugwa kuchokera ku konkire yowoneka bwino

Zifukwa zazikulu za kupukuta konkriti wonyezimira ndi izi: Kusakwanira kokwanira kowonjezera konkriti (zopangira simenti) ndi simenti kapena kusanganikirana kosagwirizana; kuthirira kwambiri pamtunda, kutayika kwa slurry pamwamba pa miyala; mphamvu ya konkire yosakwanira; komanso potsuka madera ozungulira. slurry amatayika chifukwa cha kukokoloka kwa madzi; filimu yochiritsa ikusowa. Choncho, m'pofunika kugwiritsa ntchito oyenerera permeable konkire kulimbikitsa wothandizira zipangizo; Thandizo ndi simenti ziyenera kuikidwa mu ndalama zokwanira ndi kusakaniza bwino ngati pakufunika. Mukapopera madzi kuti muwakonzere, kupanikizika sikuyenera kukhala kwakukulu, ndipo kupopera mankhwala mwachindunji ndi mapaipi amadzi ndikoletsedwa. Poyeretsa malo ozungulira, phimbani gawo la konkire lotha kutha. Pangani batching molingana ndi mphamvu ya konkriti yomwe idapangidwa. Kuphatikizika kwa filimu yochiritsa kuyenera kutsekedwa mwamphamvu, ndipo filimuyo iyenera kuphimbidwa ndikuchiritsidwa kwa masiku 7.
