Coefficient titibonelo letinkhulu tekuvumelana isihlabathi - isakhi ezidingekayo kule ukukhethwa impahla

Sand esetshenziswa emikhakheni ehlukahlukene ukwakhiwa, ngakho-ke kubalulekile ukwazi ukuthi ukubala lemali edingekayo le nto. Uma kwenzeka metering by volume, kubalulekile ukuba acabangele inkomba ezifana isihlabathi compaction isilinganiso (Umthengi esifushanisiwe). Kuyinto esisemqoka kule ukubala. Le nkomba kubalulekile ukuqonda ukuthi compaction.

Umthamo impahla

On wathi ipharamitha kungathinta eziningi izici zangaphandle, ezifana mode futhi uhla ukuthutha. Ukuze ugweme izinguquko ngevolumu isihlabathi, kubalulekile ukuvikela ngokuphelele ke ekulimaleni mechanical ingress umswakama kanye izakhi angaphandle. Hlola lokhu okubalulekile okufanele kwenzeke ngokushesha edilini lomshado, bese kumamukeli abashongo umphakeli. Ukubala lokhu ipharamitha ayiyona inkimbinkimbi. Ukuze lokhu kumele siphindwe Inani elivamile ukwaziswa Coefficient isihlabathi uphawu. Kukhona Thenga, kakade ifakwe GOST 9757-90. Akufanele kube ephakeme kunaleyo 1.15. Ukuze anqume inani langempela idingekile ukuze yokukala umthamo umzimba, kodwa kuthatha ukuphakama wangempela impahla, kunokuba ezinhlangothini.

isihlabathi compaction isilinganiso

Le nkomba incike:

• Izinga lokushisa kanye nomswakama. Ngokwesibonelo, ebusika kungase kubonakale izigaxa eqandisiwe. ivolumu yabo bubhaliwe.
• izimo ekalishi.
• ngezigaba Okubalulekile impahla ngokuvumelana GOST 25100-95 futhi GOST 8736-93 lapho nomswakama yakhe yemvelo kanye kwabantu icaciswe.
• isihlabathi compaction isilinganiso futhi incike lapho eyamukelwe ngayo. Ngokwesibonelo, impahla egodini lihlukile misela kwisitaki.

Kubalulekile acabangele Isici compaction isihlobo isihlabathi. Lesi sibalo kudingekile ukubala wathi. Ngokuyisisekelo isilinganiso kwabantu "ezomile" impahla (lwamathambo). Lokhu ucabangela isilinganiso isihlabathi compaction (SNP 2.05.02-85) ukuze ipharamitha efanayo ukuthola umthombo.

Ukubalwa kuxhomeke ezicini eziningana:

• Kusukela izici umthombo, lapho into etholakale (alluviation wokubacindezela, inkwali).
• On izimo zezulu.
• Kusukela isikimu ukuthuthwa ukulethwa impahla kusayithi kubekwa.
• On ipasipoti idatha umthombo. Kukhona baloba idatha efana nobuntu isihlabathi, ukuminyana zayo zemvelo kanye nomswakama nokunye.

Council

Ekutholweni nezinye izinkomba kufanele uthathe isilinganiso esifanele isampula impahla ebusweni mayelana 20-25 cm futhi okungenani 50 cm kusuka ezindongeni umzimba ukujula. Kubalulekile ukuba isifundo. Amasampula kwale nto kufanele kube ngokuhambisana GOST 12071-84. Futhi, ngamunye wabo kufanele ube ne-ilebula esihambisana naleli bhokisi, lapho kufanele idatha ezidingekayo ecacisiwe. Khumbula ukuthi ukuze bazivikele izindleko ezengeziwe phakathi imisebenzi, kubalulekile ekuqaleni ukuze ukubala inani isihlabathi. Okusho isihlabathi compaction isici kubaluleke kakhulu ekwakhiweni kwemigwaqo, ngoba kuthinta amandla kwesakhiwo.
