The arambe achirema muturunhuru - mavhu, girenayiti, reraimu uye gang. Bulk arambe achirema pamusoro yakapwanyika ibwe rimwe coefficient Definition GOST

Yakapwanyika - particulate zvinhu, uye ane inorganic particulate, vakawana nokupwanywa rakagadzirwa nevanhu. Rakakamurwa nesekondari. Ichi chinhu chinokosha. Primary - mugumisiro kubudiswa rwokuzvarwa ibwe: hurungudo, boulders, pumice ibwe uye nezvimwewo zvinhu. The yechipiri inotengwa nokupwanywa okuvaka tsvina akadai kongiri, Asphalt, zvidhinha.

Production nzira

Nokuti kugadzirwa yakapwanyika ibwe rinoshandiswa zvinotevera nzira: dombo, mined mune matombo, anodzvinyirirwa kune imwe mamiriro kubudikidza kuongorora. Kana pamusoro marara kuvaka masarasara achishandisa michini mukuyi.

zvoupenyu chikumbiro

Nokuda mukuru namira ehupfumi, kureva. E. Kugona kuomerera zvakasimba pamusoro, mavhu anoshandiswa jecha-simende nziyo mumaguta kukura, pakuvaka zvivako, pakuvaka mikuru uye railroads.

zvinhu Features

Inotevera inokosha ehupfumi:

• arambe achirema pamusoro yakapwanyika ibwe.
• Flakiness (chimiro).
• Frost.
• Simba.
• Radioactivity.

tsika izvi zvachose zvinoumba akati zvinhu. Next, tikanyatsoongorora imwe pfuma dzakadai arambe achirema kuti nowakapwanyika ibwe. Hazvina nemaloznachimym tsananguro.

arambe achirema kuti vanonetseka ibwe

Izvi pfuma zvokunyama wakabatana zvakananga chacho hachichinji. Under arambe achirema ndiyo nhamba vakawanda kuti vhoriyamu. It unotaurwa matani kana makirogiramu por cubic mita (t / m, makirogiramu / m³). Kusiyanisa arambe achirema ichokwadi yakapwanyika ibwe, dzakakudzingai chinhu, uye zvinonyatsorehwa hombe, t. E. Munguva uncompressed mamiriro. Mumwe nomumwe wavo ane runoenzanirana zvarinoreva.

The arambe achirema yacho mavhu kwechokwadi ndezvipi murabhoritari. Izvozvo nouremu chete chikwata vhoriyamu wakaisvonaka uye yakaoma zvinhu. Nenzira iyi haabatanidzi pamberi voids akazara mumhepo. Saka kuziva porosity.

Shoko rokuti "hombe arambe achirema marara" rinoshandiswa kureva nhamba pakati uremu uye vhoriyamu nokuparidza akasununguka nzvimbo pakati zvacho. parameter Izvi zvinodikanwa kana pakuverenga murwiyo ari chesamende nezvakasanganiswa.

arambe achirema chipimo

Muchiitiko chino, pane nzira dzakawanda kuziva:

1. Nokuyera mudziyo.
2. Nokushandiswa pamatafura.

Ngationgororei nzira yokutanga

Kuti tiite izvi kunoda kuyera mudziyo cylindrical chimiro vhoriyamu kubva 5 kusvika 50 litres kuzadza zvachose kuumba pamusoro cone. Zvadaro bvisa zvakawandisa pamusoro chimiro. Ngarava iri rairema. Kuziva arambe achirema pakati yakapwanyika ibwe, ngaaverenge musiyano pakati mudziyo izere uye chinhu, izvo yakakamurwa bhuku ngarava. Hapana kwakaoma. The yemaitiro hazvisi sezvinotevera:

• Fh = (m ₂ - m _1): V,

₁ apo M - guru ngarava chiro; mamita ₂ - pamwe detritus, V - volumetric inokwana mugaba.

Huru zvinodiwa

To nemazvo ayere hombe arambe achirema, kuteerera hurumende mitemo, muri:

• Kushandisa midziyo kushandiswa chete, kuti ndiye mumwe saizi uye chimiro.
• Kukura mudziyo anoenderana zviyo saizi.
• Vakadzvinyirirwa mhaka kwete zvakananga chisimbiso, sezvo iri nyaya, mashoko uchava zvakasiyana unongotaura.
• Vose arambe achirema hazvo yepamusoro hombe.

The Zvabuda vakawana murabhoritari, anoratidza iri nokuzadza pasipoti chaiyo batch mangé.

Kuwedzera marara, nenzira iyi inoverengwa uye kuti arambe achirema jecha, kongiri uye nezvimwewo. Panguva iyoyowo kufungawo vhoriyamu zvezviyo uye nzvimbo pakati zvacho.

Kutsunga pamwe matafura

kukarukureta uyu arambe achirema izvi zvinhu kunokoshawo. For mavhoriyamu makuru, kana mune zviitiko apo kukanganisa anenge 1% hakukoshi, kuita kwakajairika kuyera matafura pamwe coefficients shanduro. Plus nzira iyi - nguva vakaponeswa uye wakadekara. Kubvisa - munhu ine, kururama mugumisiro.

kanzuru

Zvinofanira kurangarirwa kuti unorema arambe achirema - ndiko kunaka zvepanyama, yepanyama, precluding mukana unozotevera compaction kubvisa voids.

In zvokuvakisa ndiyo imwe inokosha parameters. Kubva izvi kunoenderana simba yokupedzisira chigadzirwa uye kunanga kutsunga voids akazara zvishoma yakasimba Zvinoumba zvimwe zvinhu.

In kugadzirwa nekongiri wemisanganiswa vanotungamirirwa pokutonga: dzakanga ari chikamu chiduku, rezasi unorema arambe achirema parameters. Zivo kwayo waivako anogona yekudyidzana kuponesa. Somuenzaniso, pane imwe pasi chakapatsanurwa uye yakakwirira hombe simende arambe achirema zvaida iri shoma zvikuru. Nokuziva chaiwo vhoriyamu nyore chokufambisa uye amatura. Zvinova zvinogoneka kuverenga zvinhu kuti zvifambiswe. Uyewo muchiitiko ichi tinogona kufunga chokufambisa chinzvimbo.

arambe achirema chikonzero

Tichibata nerondedzero iyi. Technical ukoshi yaishandiswa panguva nokuyerwa bhuku mavhu, vakadamwa: unorema arambe achirema nhamba yakapwanyika ibwe. It nemaloznachimy kuita. Shandisai zvose rake zita - compaction chinhu kana kuchinjwa (kureva uremu pa bhuku yokutendeutsa ndiEzekieri).

muenzaniso

Toti motokari zvakaunzwa kuti kuvakwa marara. Kuita kuyerwa zvakafanira? Kuti aite izvi, isu nokuenzanisa chitsama mutoro uye muviri pamuganhu mukaguta. Ipapo vakawana tsika vowanda ne compression unodiwa. Zviri pachena kuti nhamba zvichava zvakasiyana nokuda "akarova" nhumbi achityaira, asi haikwanise uremu. Muchiitiko chokutanga, kufungisisa shrinkage, tinogona kutaura kuti ndicho chikuru arambe achirema amabwe akapwanyika kana kukosha pedyo nayo. In rechipiri - unorema.

Nokuti nokunzwisisa, kuti atore mumwe muenzaniso chaiyo youpenyu. Takatenga imwe mari shuga. Somuenzaniso, imwe kilogram. We nehope ari shuga mbiya, akagamuchira chikuru vhoriyamu. Vanoshamisika, akagogodza, ndokutsika. Akayera. Takagamuchira somugumisiro wokupedzisira vhoriyamu.

achifurira zvinhu

Zvakakosha kuziva. On arambe achirema kunechekuita uye erudzi, kubva yakaitwa marara. Kana imwe vhoriyamu - 1 mamita ³ panguva girenayiti kurema ndiwo matani 2,6 kubva reraimu Zvisinei, nokuda nouipi Goldstone, dolomite, etc. -... M 2.7-2.9 pamwe zvakafanana uremu achasiyana.

Somugumisiro, hombe, milled dombo kunotora nzvimbo shoma pane zvishandiswezve. Izvi imhaka pazvakaringana pakati okunze. About musiyano Vhoriyamu chete uremu uchataura chokwadi uye hombe mavhu nharaunda. Chinhu yakavimbika chokwadi. Somuenzaniso, kuti arambe achirema ose vanonetseka girenayiti chakapatsanurwa (zviyo saizi) inobva 5 kusvika 20 mm vechokwadi achava 2590 makirogiramu / m ^3, uye unorema chete zvinhu zvichava 1320 makirogiramu / m³. Saka, achiziva tsanangudzo iyi, tinogona substantially tichengetedze mari zvinoderedza nokusanganisa kongiri kunovhengana, uyewo pamusoro nzira yokufambisa uye okuchengetera nzvimbo.

vamwe mikana

Muchiitiko chino, unogona kusimbisa zvinotevera:

• Chakapatsanurwa - tsanga kukura zvinhu. Kusiyanisa mwero (5-10 neMM, 10-20, 5-20 , uye zvichingodaro.), Non-mureza (10-15 neMM, kubvira 15 kusvika 20 neMM, uye t. D.) Uye evroscheben (3-5 mm).
• Brand marara simba. Several marudzi akasiyana. Kureva, zvatinosiita simba M 800-1200; soro - M 1400-1600; Svikiro - M 600-800; simba - 300-600 M; Minimum - M 200.

The raora of webato, muchiso uye dombo chepakutanga huchachinja unorema arambe achirema.
