Sand-grit osakaniza, amene ankadziwika ndi acronym PGS tichipeza 50 peresenti ya osiya ndi yofanana chomenyedwa. Okhutira wa Chofunika, kapena miyala ayenera kukhala osachepera 15% ya kulemera okwana. Nkhanizi analandira mwa kuphwanya miyala pano akhoza zimachitika zosiyanasiyana zachilengedwe.

mafotokozedwe ambiri

Sand-grit osakaniza ali makhalidwe kwambiri ngalande ndi mtengo wotsika. mfundozi awiri kupanga zinthu wotchuka kwambiri mu kukonza ndi kumanga. Ndi loyenereradi wosindikiza zigawo mu kukhazikitsa ntchito msewu. Zikuchokera singasiyanitsidwe Pamene ntchito simenti, ndi m'madera ena bwalo. Zimakhala gawo ndi Crane runways. Konsekonse applicable zikuchokera Kulinganiza moyenerera sitima embankments, komanso kupanga phula kasakaniza.

PGS gulu

Sand-grit osakaniza akhoza ogwira kapena zachilengedwe, yoyamba amapangidwa ndi patsogolo zachilengedwe. Mwazina, n'zotheka kuonetsetsa magulu ena a zipangizo, kuphatikizapo C2, kutanthauza factionalism mkati 20 millimeters. Pankhani zikuchokera kwa acronym C4 kapena C5, ndiye pamaso panu timene millimeters 80. C6 lakuti komanso limasonyeza factionalism pakati pa 0 ndi 40 millimeters. zogulitsa Tingaone ndi C12, kutanthauza kulolerana wa millimeters 10. Malinga ndi cholinga cha osakaniza ukhale wa mitundu zotsatirazi: wokutira ndi motorways m'munsi ndi airfields, chifukwa ballasting sitima embankments ndi kupanga phula kasakaniza.

Ntchito miyala-mchenga

Sand-grit osakaniza, malingana ndi ntchito, ndi makhalidwe ena apamwamba. Choncho, miyala, mchenga ntchito misewu ndi airfields, angathe kupereka kufunika mphamvu ❖ kuyanika kapena m'munsi. Mwa zina, ntchito kulimbikitsa roadsides. Mchenga ntchito ballasting embankments ntchito m'gulu la m'mabande a osiyanasiyana mtanda magalimoto kwambiri ndiponso kuti chimasiyanitsa filler wachiwiri kuchokera imodzi yoyamba kuti ndi kapepala ambiri cholinga. Kupanga yake lidzakwaniritsidwe onongani luso serpentinite. The particles analandira chifukwa, kukula sayenera upambana 25 millimeters.

Wosweka mwala mchenga osakaniza (GOST 9128-97 mosamala Kuchititsa pa kupanga) angagwiritsidwe ntchito phula zosakaniza, ndipo ndi chuma amene analandira m'kati onongani miyala. The zikuchokera ntchito monga mchere chigawo chimodzi cha osakaniza umatulutsa. particles The zingasiyane kukula millimeters 1 mpaka 20.

Waukulu Mkhalidwe ubwino

Wosweka mwala ndi mchenga osakaniza C4 nthawi zambiri poyerekeza ndi makhalidwe ukonde. The zokolola yamasika zosiyanasiyana zizindikiro. Pakati pawo, pali kufunika kuonetsetsa mtengo wotsika, kuposa chisindikizo quality, komanso njira yotsika yosavuta kugwiritsa ntchito. Chifukwa osakaniza anafotokoza ali zikuchokera mchenga, miyala ndi mwala wosweka, zimatha chomaliza zosakaniza bwanji makhalidwe a zigawo zitatu. Chofunika kwambiri ndi mphamvu ya makhalidwe, phindu pazipita amene ali M1400. Izi njira wanyamula miyala chabwino zipangizo mkulu-mphamvu. N'kosatheka kuti wodzipatula ndi chisanu, omwe okonzeka zopangidwa mchenga grit kusakaniza. mtundu wawo zikhoza kugulidwa pa msika zipangizo yomanga. The PGS ambiri ndi F300 ankachita. The zili fumbi ndi dongo particles angafikire 20%, njirayi tiyenela kuiganizila pamene kugula zinthu.

Pomaliza

Sand-grit osakaniza ali ndi kuchuluka kwa makhalidwe abwino, ambiri a iwo akhala kutchulidwa nkhani. Ngati mukufuna kugwiritsa ntchito yomanga ya kapangidwe anafotokoza, m'pofunika kuti bwino mitengo pachiyambi. The ndalama pafupifupi yomanga zipangizo pa zapansi wa lero - 400 rubles pa mita kiyubiki, imene tingati ndi mtengo wololera, amene sangakwanitse mwini m'tsogolo wa nyumba payekha. Ndipo ndi - koma wina mwa ubwino wa chuma anafotokoza.
