Maseŵera akale a asphalt angakhale monga akutsatira malamulo, kapena aganizire pamasewerowo. Mulimonsemo, pa masewerawa mutha kukhala ndi nthawi yokondweretsa komanso chidwi.
Kodi ndi bwino bwanji kusewera mwachikhalidwe?
Pali kusiyana kwakukulu kwa masewerawa, ndipo n'kosatheka kunena mosapita m'mbali kuti ndi yani yomwe ili yolondola. Ambiri amagwiritsidwa ntchito ndi awa:
"Zovuta zamakono"
Pokonzekera masewerawa pa malo otchedwa asphalt, ndondomeko yotsatirayi imachokera ndi choko:
Gawo lirilonse, kapena lalikulu, mmenemo liyenera kukhala ndi usinkhu wa 40x40 kapena 50x50 masentimita. Asanayambe masewerawo, ophunzira ndi maere kapena njira zina amatsimikizira kuti nthawi yayitali. Kenaka, wosewera woyamba akuponya mwala kapena chinthu china, m'malo mwake, pa "kalasi" yoyamba, kenako akudumpha: phazi limodzi pa 1, 2, kenako awiri pa 3-4, kachiwiri mmodzi pa 5, awiri pa 6-7, pa 8 mpaka kachiwiri pa 9-10. Pambuyo pake, kudumphira kumaphwanya madigiri 180 ndipo kumachita chimodzimodzi mosiyana, potsatira njira yokwezera mwalawo ndi kutenga nawo. Pachifukwa ichi, patukani kumbali yanu, kapena mwachitsanzo, nyamukani miyendo iwiri, ngati mukufuna kuima pamodzi pa masewerawo, simungathe. Ngati chirichonse chikuchitidwa molondola, chinthucho chimasuntha ku "kalasi" yachiwiri. Momwemonso, imasunthira pamapeto pake, ndiko kuti, pamtunda ndi nambala 10. Ngati wosewerayo alakwitsa, mwalawo umaloŵa m'khola, ndipo wosewerayo "amawotcha" kalasi imodzi, ndiko kuti masewerawo "amabwerera mmbuyo" angapo akubwerera mmbuyo.
"Zakale zachikhalidwe"
Njira yachiwiri ikuphatikiza kugwiritsa ntchito njira yotsatirayi:
Pano, mwala umatsanulidwa kuchokera pa 1 mpaka 10 "kalasi", ndipo osewera amatha kulumpha pa mwendo umodzi, akusuntha kuyambira pachiyambi mpaka kumapeto. Muzigawo zamakono mungathe kusewera ndi mwala ndi chinthu china chilichonse.
Zovuta Zakale
Chifukwa cha masewerawa, omwe nthawi zina amatchedwa "nkhono", pa choko cha asphalt chimapanga chiwembu chotere:
Wopewera woyamba akuponya mwala mu selo yoyamba, kenako akudumphira mu phazi lomwelo, kuyesera kuti asakhudze mizere iliyonse. Ndiye ndi chala cha phazi, ayenera kusunthitsa mwalawo ku selo lotsatira, koma kuti lisakhudze mizere iliyonse. Apo ayi, kusamukira kumasewera wina. Kuti apambane, wophunzirayo ayenera kudutsa lonse "nkhono" ndikubwerera. Kusewera masewero ozungulira kumatheka ngati kucheza ndi anyamata ena, ndipo chimodzi, ndicho chopindulitsa chofunikira cha masewerawa.
