Anajambulapo wosweka mwala ntchito yomanga

Laimu miyala ntchito mu ntchito liza, komanso kupanga feteleza mchere ndi mandimu. nkhani yogwira opangidwa mwa kuphwanya ndi sieving thanthwe zina, zomwe ndi laimu.

mafotokozedwe ambiri

Zodula kwambiri ndi makhalidwe ndi khalidwe limene analandira mu processing wa thanthwe ndi kashiamu carbonate. zosafunika zosiyanasiyana ndi zina kuchepetsa ubwino ndi makhalidwe a miyala zothandiza chomenyedwa. Zinthu zimenezi si cholimba kwambiri, koma katundu monga mtengo wotsika, kukana kuti chisanu, komanso ngozi zachilengedwe, kupanga izo nkhani mpikisano kwambiri pa ntchito yomanga.

makhalidwe luso

Laimu miyala ali kukana chabwino zodabwitsa ikukhudzana yodziwika ndi mphamvu zabwino ndi zochita ngati zinthu wochezeka. Frost kukana ndi madzi mayamwidwe chomenyedwa ndi pa mlingo mkulu. Ngati chiwerengero ndi kuchuluka zosafunika ndi otsika, nkhani ali pabuka bulauni kapena wachikasu kulocha. Poyerekeza ndi Miyalayo, miyala miyala kuti ali mpweya wa poizoni otsika ndi mkulu guluu wolimba kwambiri. Potsilizira pake dolomite akhoza kuwapeza amene ali mphamvu yapamwamba ndi makhalidwe durability. Nthawi zambiri iwo poyerekeza ndi makhalidwe lubwe ndipo ngakhale pamaziko a osalimba chochuluka. Anajambulapo mtundu uli zochepa otsika chochuluka chiŵerengero. Izi zimathandiza kuchepetsa mowa wake. Mtengo wa zinthu kwambiri m'munsi poyerekeza ndi mankhwala ofanana mitundu ina ndi zipangizo.

katundu Ofunika

Laimu miyala ali mitundu angapo. Monga momwe zochitika zogwirizana kwambiri cuboid, flakiness index ali mkati 10%. Chisakanizo cha zinthu zayamba wopanda voids, amasonyeza kusakumvekamveka otaya njira binder. zosiyanasiyana zimenezi chimagwiritsidwa ntchito monga mwala kukongoletsa pomanga misewu, umene ndi katundu chidwi. kachulukidwe zakuthupi si upambana 80 MPa. kukana ake chisanu ndi mkulu mokwanira, n'chifukwa chake chomenyedwa angathe likufa kuti m'zinthu 125 m'firiji pamtunda ndi mazira. Madzi mayamwidwe zimasiyanasiyana 1 2.2%. Ngati ife kulankhula za wearability, ndi ofanana ndi malire a magalamu 0.3-0.8 pa centimeter lalikulu. Mbali yofunika ya kulemera yeniyeni ndipo kuyambira 1260 kuti makilogalamu 1320 pa mita kiyubiki.

akuphwanya

Kuti apange chomenyedwa anajambulapo kumanga nyumbayo, m'pofunika kupeza. Madipoziti zinthu zambiri, pachifukwa ichi, ndi chuma zaphindu kupeza kuchokera quarries ozungulira. Migodi ikuchitika mwa kutsegula, pambuyo zikutchinga yaing'ono. Pa gawo lotsatira, potsegula miyala ndi excavator chinthu, dongosolo lalikulu kulowa makina onongani. Pamodzi ndi yaing'ono chikhalidwe kachigawo sieving limapezeka kupyolera sieve wapadera. Koyamba mosamala ndi kusanja kwa tuzigawo twa zina zoyenera ndi zomwe zagwiridwa ndi kusanja ndi mfundo mu "kubangula" atha kutumikira ngati chitsanzo. Kenako, zinthu zikhoza kuwapeza, kumene kungakhale yaing'ono, sing'anga kapena coarse nusu. Pamene kusanja zipangizo zamakono kuti amalola kuthandauza kuchuluka ndi ntchito.

ntchito

Kupanga zinthu zinalongosoledwa zochokera kwa GOST chisoni anajambulapo angagwiritsidwe ntchito pogwira ntchito zosiyanasiyana. Pankhani krupnofraktsionnyh zinthu, iwo ntchito pomanga misewu. Koma yaing'ono kapena sing'anga yabwino kwa Kutaya zigawo chapamwamba cha misewu kapena dongosolo la mankhwala konkire. Pamaso kugula zinthu n'kofunika mutidziwe bwino zikalata yoyenera ndi malangizo omwe alembedwa mu makhalidwe Mkhalidwe ndiponso kudalirika kwa nkhaniyo. Musanayambe kugula wosweka lubwe, miyala, akatswiri amalangiza kulabadira mpweya wa poizoni ake. Komabe, ngati pamaso panu apamwamba chuma, zimakwana adzakhala otsika kwambiri, kusonyeza kuti zachilengedwe ndi chitetezo.

Ntchito tizigawo tosiyanasiyana a miyala

Atavutika anajambulapo (GOST 8267-93) Mwina ndi tuzigawo twa osiyana. Pankhani kukula kwa zinthu kuchokera millimeters 5 mpaka 20 kutsogolo kwa inu finely kuuluka zakuthupi. Izo ntchito mu kupanga kasakaniza konkire. Konkire oversized yamanga nthawi zambiri chopangidwa ntchito imeneyi kachigawo laimu miyala. Chimagwiritsidwa ntchito zinthuzi kuti akalowa wa nyumba, komanso kupanga laimu. Atavutika amene kachigawo ranges ku millimeters 20 mpaka 40, ntchito kaŵirikaŵiri poyerekeza ndi zinyama zina. Monga munda waukulu ntchito ya mafunde mokomera maziko, mwa zina, pamafunika chirichonse nsanja ndi mayendedwe, amene pambuyo kuchiritsa tikhale ndi maonekedwe bwino ndiponso yaitali kusunga makhalidwe ake apamwamba. The malangizo chachikulu cha zinthu zimene kupanga nyumba analimbitsa simenti ndi kumanga misewu, amene ali mwa ntchito ongoyendayenda kwambiri.

Ntchito krupnofraktsionnogo chomenyedwa

Ngati zinthu zakuthupi ndi miyeso mu osiyanasiyana millimeters 40 70, izo zikusonyeza kuti ntchito infrequently. The malangizo zofunika - ndi ballast wosanjikiza miyala kapena makonzedwe a mapilo. Ndithu sichipezeka pamene nkhaniyo ili nusu ntchito pamakoma cladding. Izi zikhoza kukhala zoona kokha chifukwa ntchito zikuluzikulu.

Choncho, wotchuka kwambiri ndi makhalidwe a kachigawo pakati. Chili ngati singasiyanitsidwe zomangila amene ali katundu kwambiri kumangako ndipo ndi filler kwambiri. Pakati mbali yake kusiyana kukana ozizira, komanso mphamvu pazipita kuti amalola zinthu ntchito mu nyengo capricious ndi kusintha mwadzidzidzi kutentha ndi chinyezi.

Kuipa ndi zofooka

Musanayambe kugula chomenyedwa anajambulapo M600, muyenera mutidziwe ndi mphamvu zonse ndi zofooka za nkhaniyi. Choyamba, tiyenera kukumbukira kuti mtundu wa miyala si monga cholimba poyerekeza miyala. Komabe, kuipa umenewu udzatha. Polingalira za chitetezo, izo bwinobwino ntchito yomanga nyumba zosiyanasiyana ndi nyumba cholinga zogona. Migodi ikuchitika mosavuta poyerekeza zipangizo zofanana, ali ndi ubwino mtengo. Anajambulapo chomenyedwa ali mphamvu otsika, nchifukwa chake ntchito yomanga maofesi a lalikulu ndi zosayenera, kuti si nthawi zonse yabwino. Komabe, mwangwiro amasonyeza ntchito yake yabwino kupanga analimbitsa nyumba konkire zamitundu yaing'ono.
