Kuchuluka kwa ntchito:
Konzani madera ang'onoang'ono a misewu yowonongeka monga misewu ya konkire ya phula, misewu ya simenti ya simenti, malo oimikapo magalimoto, maulendo a ndege, maulendo owonjezera mlatho, ndi zina zotero. Zida zozizira zozizira zimagwiritsidwa ntchito makamaka pokonza pothole, kukonza groove ndi ma ruts ogwirira ntchito, zophimba za manhole ndi kukonzanso kozungulira, ndi zina zotero. Zida zokonza nyengo zonse, zoyenera kutentha kwakukulu.
Mafotokozedwe Akatundu:
Cold-patch phula chowonjezera ndi chowonjezera chopangidwa ndi ma polymerizing modifiers ndi zida zosiyanasiyana. Amagwiritsidwa ntchito makamaka popanga phula lozizira.
Bitumen ozizira chigamba zinthu akhoza kumangidwa mu kutentha osiyanasiyana -30 ℃ mpaka 50 ℃. Kusungirako thumba kumalimbikitsidwa. Zida zozizira zozizira zimagwiritsidwa ntchito makamaka: mtengo wokonza wotsika, wosakhudzidwa ndi nyengo ndi kukula ndi kuchuluka kwa maenje, ndipo angagwiritsidwe ntchito ngati pakufunika.
Kumanga kosavuta: Molingana ndi mikhalidwe yosiyana ya msewu, compaction compaction, manual compaction kapena galimoto matayala rolling angagwiritsidwe ntchito kukonza kukonza khalidwe; maenje okonzedwa samakonda kugwa, kusweka ndi zochitika zina zosafunika.
Njira yosungira:
Zowonjezera za phula zoziziritsa kuzizira ziyenera kusungidwa m'migolo yotsekedwa m'nyumba yosungiramo mpweya, yozizira. Akhoza kusungidwa kwa zaka ziwiri. Pewani kuziyika padzuwa kuti kutentha zisawonongeke, ndipo pewani ku zinthu zoyaka moto ndi zinthu zotulutsa okosijeni kwambiri.
Momwe mungagwiritsire ntchito zinthu zoziziritsa kuzizira (zozizira zozizira kuti zikonze maenje):
1 Kupukuta, kuphwanya, kudula ndi kuyeretsa.
2. Utsi kapena kupaka mafuta wosanjikiza;
3. Patsani zinthu zoziziritsa kukhosi pafupifupi 1CM pamwamba pa msewu. Kuchuluka kwake kukakhala kopitilira 5CM, kumafunika kupakidwa m'magawo ndikuphatikizana m'magawo;
4. Kuti muphatikizepo, mungagwiritse ntchito ma tampers a flat plate, tampers ogwedezeka, kapena mawilo a galimoto kuti aphwanye ndi kuphatikizika;
5. Ikhoza kutsegulidwa kwa magalimoto pambuyo pa kuphatikizika.
Zindikirani: Kutentha kukakhala kotsika, zinthu zoziziritsa kukhosi ziyenera kuyikidwa m'nyumba yosungiramo zinthu pamwamba pa 5 ℃ kwa maola 24 isanamangidwe. "Phunzirani zazinthu zina".
