Ingxenyenamba 20-40 - egwadle luthuli: isisindo sayo, ukuminyana, kanye nezinye izici

Uma enze izinhlobo eziningi ukulungisa noma emsebenzini wokwakha kudinga ukusetshenziswa rock olwembiza. Ukuze ukwazi ayisebenzise ngezinhloso ezithile, itshe ochotshoziwe eyenziwe imibango ezahlukene. Material owayemude encane isetshenziselwe izinjongo zokuhlobisa, lo ingxenyenamba indawo edingekayo ukwakhiwa lezinto ezibaluleke esindayo.

Usayizi isilinganiso wamaqhuzu - 20-40. egwadle Nechobozekile lokhu usayizi ithandwa kakhulu. Quartz diorite noma egwadle isetshenziselwa ukukhiqizwa yayo.

ukwakheka impahla

Granite - kubhekwa edwaleni kanzima kakhulu, etholakala emhlabeni. Ngenxa yamandla ayo ekhethekile, wenza egwadle izinto, kuhlanganise amatshe asetshenziswa lapho amasayithi ukwakhiwa luzovezwa ngesikhathi ukusebenza kuze layisha okusezingeni eliphezulu. Futhi ngenxa yokuthi i-rock egwadle okujwayelekile cishe zonke zithi, izindleko zokwakha ezivela luhlala kufinyeleleke futhi ethandwa.

Umbala izinto kuxhomeke kulokho namaminerali aqukethe egwadle, kodwa ngokuvamile uye umbala kusuka obomvu grey. Ngemva contact kokuncinyane amaminerali impahla amnyama ungase ube ukubukeka nezinala.

nzuzo ngisho noma engalalela

Ingxenyenamba 20-40 - egwadle luthuli, okuyinto kubhekwa yamathebhu kangcono emkhakheni wezokwakha. Siyabonga ukusebenzisa kwayo kungenzeka ngaphandle nobunzima ukuze ugcwalise amafomu afanele, ukulondoloza, futhi kakhulu kakhulu, amamiksi ezibizayo ukhonkolo. Njengoba okusanhlamvu egwadle ube nohlobo anolaka oqoshiwe, adhesion kakhulu kwenzeka izingxenye, iqinisekisa adhesion esihle esemazweni impahla.

Uma kuqhathaniswa nezinye imibango ubukhulu, kuba okusanhlamvu isilinganiso ekhiqizwa ne aphansi zabasebenzi, iqinisekisa kufinyeleleke kakhulu izindleko impahla.

izakhiwo

Ukusebenza kuncika izakhiwo ezilandelayo:

1. Ingxenyenamba 20-40 - egwadle luthuli, okuyinto inenani bafake ukumelana nokubamba.
2. Indaba zingamelana i isibalo esingapheliyo nqabela / ncibilika hhayi iba yingxenye yomhlabathi.
3. Ukuba khona flakiness ongaphakeme. Inani Isisindo okusanhlamvu kancane ezithinta flat bobunjwa, inaliti ngakho ohlangene kalula amatshe zobuningi imiklamo izigqulo.
4. ochotshoziwe egwadle 20-40 Wugqinsi incike zohlobo senziwa kuyiphi. Ngokwesibonelo, impahla egwadle cube ukala mayelana 1370-1400 kg limestone - 1280, gabbro, diabase - 1440 kg.
5. porosity Amancane. Ukungabikho pheze ephelele ikhule ezimbotsheni kusiza komkhawulokudonsa high and low amanzi ukumuncwa Coefficient.
6. radioactivity okuphansi. Le mfanelo ibaluleke kakhulu, ngoba ikuvumela ukusebenzisa umsebenzi wokwakha izakhiwo zokuhlala, commercial, umphakathi kanye yezimboni. Le nombolo sihlanganisa izinkulisa, izikole kanye nezibhedlela.

ukuhambisana GOST

On egwadle ochotshoziwe 20-40 GOST 8267-93 icacisa inani izinkomba ezilandelayo:

• 5-23% flakiness;
• lichaza ekwakheni akufanele bube ngaphezu kuka-0.5% lokusanhlamvu 5 mm ezingaphezu kuka-10% izingxenyana mancane ukudlula u 20 mm.
• uthuli ubumba akumele leqe 0.3%;
• Lines 1000-1400 amandla;
• isisindo 1 m3 egwadle luthuli 20-40 - 1.35 amathani;
• khona izigaxa ngobumba - okungenani 0.25%;
• khona ezithambile idwala izinhlayiya - akukho kuka 5%;
• usayizi ngobuningi kwabantu mayelana 2.7 g / cm ^3;
• ukukhuthazela - Inkomba I1.
• iphesenti amanzi ukumuncwa - ezingeqi kwezingu 0.4%.

Ngaphezu kwalokho, izinto kumele abe Izakhiwo ezilandelayo:

1. Inkomba frost ukumelana - F300.
2. radioactivity ezingeni kumele singeqi 370 Wh / kg.

Phakathi ukuzimisela kokuhlaziywa lomkhiqizo senzeka kulezi nezinye izici imfucumfucu.

Ububanzi

egwadle Nechobozekile has izakhiwo chemico-ngokomzimba okunikeza ukusebenza kakhulu impahla. nobukhulu bayo kuchazwa usayizi okusanhlamvu.

Ingxenyenamba 20-40 - egwadle luthuli, esisetshenziselwa:

1. I izixazululo ukhonkolo.
2. Ngenkathi kwakhiwa kwagcizelela izakhiwo zikakhonkolo.
3. Phakathi kubekwa izisekelo.
4. Njengoba kwabantu ngobuningi ngoba base ngaphansi ishidi asphalt.
5. Ukuze kuqiniswe noma ukuqondanisa komgwaqo.
6. Lapho yokupaka kudivayisi izimoto.
7. Ukuze izindawo zesikhashana lapho kuzodlalelwa khona imishini yokwakha.
8. Ngenkathi kwakhiwa nemizila tram ukuthutha.
9. Ukuze lukhuni ebusweni ngaphansi w / e yokugijima.

ukuthenga Izici

Thina lapha asikhulumi ngama-inqubo wokutholakala kukhethwa impahla. Okubaluleke kakhulu, indaba wahlangana wonke specs, futhi lokhu kungenzeka kuphela uma ihlangabezana nezidingo GOST. Kodwa ingabe kunjalo ngempela yiziphi izinto ezintathu ezibalulekile izici ezichazwe kule dokhumenti zomphakathi? Kwenzekani uma amatshe ngeke ukuhlangabezana nezidingo ngenhla GOST?

Njengoba lokhu kuqinisekiswa umkhuba, noma yiziphi izinguquko kuhilelani ukuwohloka. Ngokwesibonelo, uma okusanhlamvu flat isisindo Imininingwane ingaphezu ebekiwe etholakala nge ukusebenzisa kwabo izinga kancane ukhonkolo, kanye nenani mix ukhonkolo kwakuzodingeka ukwandisa, okuholela ngezindleko lenyuke.

Uma ochotshoziwe egwadle 20-40 isisindo lincane (noma ngaphezulu) kuka kuyadingeka, Ngakho-ke, ngo-ngezithako zawo, kukhona okusanhlamvu nezinye maqembuqembu. Ngakho, aba maningi isisindo, kulapho mass Imininingwane okusanhlamvu okuhle, futhi okuphambene nalokho: izinhlayiya ezinkulu luthathe isikhala esiningi, ngakho imfucumfucu olunjalo belungaphelelwa nesisindo esingaphansi.

Ngakho-ke, ukuthenga impahla ukuthi ngeke abe nezici oyifunayo, ukuthenga kuyadingeka ukuqinisekisa ukuthi une isitifiketi, esiphethweni sanitary-epidemiological, izici ngezinyathelo zenhlanzeko okwakufanele umkhiqizo kanye ipasipoti yayo.
