Chosefera chikwama kapena thumba ndi chipangizo chosefera mpweya phula kusakaniza chomera. Ndi chida chabwino kwambiri chowongolera kuwononga kwa zomera za asphalt. Imagwiritsa ntchito kuchuluka kwa matumba m'chipinda chosefera mpweya. Mpweya umapangidwa kuti udutse m'matumba ndipo chifukwa chake fumbi lonse limamatira m'matumba.
Zosefera zikwama zambiri zimakhala ndi zikwama zazitali za cylindrical zotolera fumbi. Matumba amenewa adzaikidwa mkati mwa makola kuti athandizidwe. Mipweya idzadutsa kuchokera kumapeto kwa thumba kupita mkati. Izi zidzapangitsa fumbi kumamatira kumapeto kwa thumba la fyuluta. Nsalu zolukidwa kapena zofewa zimagwiritsidwa ntchito ngati zosefera.
Nyumba zamathumba, zakhala zikuwongolera fumbi mumitengo ya asphalt kwa zaka zambiri. Iwo akupitiriza ntchito yawo ngakhale lero. Lingaliro lofunikira ndilofanana, zida zatsopano zosefera ndi njira zatsopano zothetsera mavuto zimawapangitsa kukhala osinthika kuposa kale.
Kugwiritsa ntchito fyuluta yachikwama pamitengo ya asphalt:
Zosefera zachikwama za chomera cha phula zimagwiritsidwa ntchito poletsa kuipitsidwa. Zidzathandiza kuthetsa dist ndi mpweya woipa. Fumbi limapangidwa kuchokera pazophatikizira ndipo nthawi zambiri sitikufuna kuti fumbi lowonjezera lilowe muzinthu zomaliza. Idzawononga chomaliza. Mpweya woopsa umatulutsa chifukwa cha chowotcha chomwe chimayatsa ng'omayo. Mipweya imeneyi pamodzi ndi fumbi amapangidwa kudutsa m'matumba a fyuluta kuti ayeretsedwe.
Zosefera m'matumba zimakhala ngati chipangizo chachiwiri chowongolera kuipitsidwa. Zosonkhanitsa zoyamba za fumbi ndi olekanitsa chimphepo. Olekanitsa oyambirirawa amatchera fumbi lolemera kwambiri poyamwa ndi kupanga chimphepo chamkuntho mkati mwa chipindacho. Fumbi lopepuka komanso mpweya wowopsa sizingatsekerezedwe ndi izi. Apa ndipamene kufunika kwa zosefera thumba phula kusakaniza zomera akukhalapo. Mpweya ukathawira pa cholekanitsa chimphepocho udzalowera kuchipinda chachikulu. Nyumba zonse zamatumba zimakhala ndi chubu kapena chimango chomwe matumbawo amapachikidwa. M'kati mwake muli ma baffle mbale. Mabaffle awa amasunga fumbi lolemera kwambiri ndipo sangalole kuti awononge zosefera. Monga thumba fyuluta adzakhala mosalekeza ntchito. Fumbi lomwe likudutsamo lidzakhala pang'onopang'ono komanso lokhazikika pamwamba pa zosefera. Izi zipangitsa kukwera kwamphamvu ndipo njira yoyeretsera imathandizira kuyeretsa matumba nthawi zonse.
Poyeretsa matumba, makina ozungulira a fan pamwamba pa fyuluta amalola kuyeretsa matumba 8 okha nthawi imodzi. Izi ndi zabwino chifukwa matumba ochepa amapeza mpweya wabwino. Chifukwa chake kuyeretsa ndikothandiza kwambiri. Kuthamanga kwa mpweya komwe kumatulutsidwa ndi fan pamwamba kudzathandiza kutulutsa keke yafumbi yomwe idzapangidwe kunja kwa matumba. Pali polowera mpweya wakuda ndi potulukira mpweya wabwino. Pansi pake nyumba yachikwama idzakhala ndi potseguka kuti aponye fumbi losonkhanitsidwa.
Njirayi imatithandiza kugwiritsa ntchito matumba mosalekeza popanda vuto lililonse. Ndizokwera mtengo komanso zothandiza.
Kusamalira matumba a fyuluta a zomera za asphalt
Matumba osefera mu zosakaniza za asphalt amagwiritsidwa ntchito poyera kuzizira kwambiri komanso mpweya wowononga kwambiri. Pali fakitale ina yomwe imayika zovuta pamatumba a fyuluta izi ndi kusinthasintha pafupipafupi kwa kutentha, kuyamba ndi kutseka zipangizo, kusintha mafuta osiyanasiyana. Nthawi zina malo ovuta komanso fumbi ndi chinyezi chambiri zimayikanso mphamvu zambiri pazosefera.
Kupanikizika mkati mwa chipinda cha fyuluta ya thumba kuyenera kusungidwa kuti matumba apitirize kugwira ntchito bwino. Komabe nthawi zambiri makasitomala amafuna kugwiritsa ntchito zidazo ngakhale kukugwa mvula ndipo izi zitha kukhala zowopsa. Nthawi zina mafuta a thumba awononga kwambiri zosefera za thumba ndipo zimafunika kusinthidwa nthawi yomweyo.
Kusintha matumba ndi ntchito yowononga nthawi komanso yotopetsa yomwe imafuna kuti chomeracho chitsekedwe ndipo ndi ntchito yonyansa. Matumba onse ayenera kuchotsedwa pamwamba pa thumba fyuluta ndiyeno matumba atsopano ayenera kulowetsedwa mu khola lomwe lilipo. Pamene mazenera akuphatikizidwa, ntchitoyo imakhala yotopetsa.
Mukakhala ndi zosefera zachikwama zoyenera zokhala ndi zida zanu mumatsimikiziridwa kuti simukuchita bwino. Kambiranani nafe ngati mukufuna kuti tigwirizane ndi zosefera zamatumba muzomera zanu za asphalt zomwe zilipo.
