Pakadali pano, njerwa zomwe zimagwiritsidwa ntchito kwambiri ndi akhungu amsewu ndi njerwa za ceramic akhungu zamsewu, njerwa zapamsewu za simenti, njerwa zapamsewu zakhungu, njerwa zapamsewu wa mphira, ndi zina zotere, chilichonse chimakhala ndi zabwino zake.
Msewu wakhungu ndi mtundu wa malo amsewu omwe ndi ofunikira kwambiri kuyika, chifukwa ndi tile yapansi yopangidwira mwapadera kwa akhungu., bolodi lamsewu wakhungu, kanema wamsewu wakhungu.
Njerwa zoyala misewu akhungu nthawi zambiri zimamangidwa ndi mitundu itatu ya njerwa, imodzi ndi njerwa yowongolera, yomwe imatsogolera akhungu kupita patsogolo ndi chidaliro, yomwe imatchedwa njerwa yapamsewu wakhungu, kapena njerwa yolondolera kwa akhungu. msewu;ina ndi njerwa yachangu yokhala ndi madontho., kusonyeza kuti pali chopinga pamaso pa wakhungu, ndi nthawi kutembenuka, amatchedwa akhungu msewu njerwa, kapena wakhungu msewu wotsogolera njerwa;mtundu wotsiriza ndi njerwa yochenjeza za ngozi yapamsewu yakhungu, kadontho kamakhala kokulirapo, apolisi sayenera kupitirira, ndipo kutsogolo kwake ndi koopsa.
Mitundu yeniyeni ndi iyi:
1. Njerwa ya ceramic yakhungu.Ndi zinthu za ceramic, zomwe zimakhala ndi porcelainization yabwino, kuyamwa kwamadzi, kukana chisanu ndi kupanikizika, maonekedwe okongola, ndipo amagwiritsidwa ntchito m'malo omwe amafunikira kwambiri monga masitima apamtunda othamanga ndi ma subways, koma mtengo wake ndi wochepa kwambiri. okwera mtengo.
2. Njerwa zapamsewu za simenti.Mtengo wopangira njerwa zamtunduwu ndi wocheperako, ndipo zinyalala zachiwiri zobwezeretsanso zinyalala zitha kugwiritsidwa ntchito.Ndiwokonda zachilengedwe komanso wotchipa, ndipo nthawi zambiri ndi yoyenera pazosowa zotsika monga misewu yanyumba.Koma moyo wautumiki ndi waufupi.
3. Sintered blind road njerwa.Njerwa zamtunduwu zimagwiritsidwa ntchito kwambiri, zomwe zimagwiritsidwa ntchito mbali zonse za misewu yamatauni, zoyenera kugwiritsidwa ntchito panja.Koma n'zosavuta kukhala zauve ndi zovuta kuzisamalira ndi kuyeretsa.
4. Njerwa ya msewu wa mphira.Ndi mtundu watsopano wa akhungu msewu mankhwala njerwa, amene ali oyenera kukonza zosintha mu siteji oyambirira, ndipo ntchito pomanganso kenako akhungu msewu njerwa, amene ndi yabwino yomanga.
Njerwa zapamsewu zosawona zimagawidwa kukhala njerwa zapamsewu zachikasu ndi njerwa zotuwa, ndipo pali kusiyana pakati pa njerwa zoyimitsa ndi njerwa zapatsogolo.
Zomwe zimafotokozedwa ndi 200 * 200, 300 * 300, zomwe ndizomwe zimagwiritsidwa ntchito ndi boma m'malo ogulitsira ndi masitima apamtunda.
