Iyini i-Optimal Density Range ye-20mm Gravel emaphrojekthini wesakhiwo?

Isikhathi:27 kuMfumfu 2025

Igravel iyingxenye ebalulekile kwi-Infra throw project eningi, isebenza njengemathiriyeli eyisisekelo ekwakhiweni. Phakathi kweziningi osabekayo, igavel elingu-20mm lisetshenziswa kahle ngenxa yokuguquguquka kwayo nokuqina. Ukuqonda ibanga eliphezulu lokuhlala elingu-20mm gravel kubaluleke kakhulu ukuqinisekisa ubuqotho bokwakha nempilo yempilo ye-Infra throw projects.

Ukubaluleka Kwe-Density yeGravel

Ubukhulu bokwesekwa kwemigodi buhlobene nezici eziningi zokwakha, kufaka phakathi:

• Iziqinisekiso zokuphatha umthwalo: Ubuningi obuphakeme ngokuvamile buhunyushwa kamnandi ekuhlinzekeni nasekusekeleni umthwalo.
• Izici zokukhipha amanzi: Ubunzima obufanele baqinisekisa ukukhipha amanzi kahle, kugwema ukugcwala kwamanzi nokukhukhumala.
• Ukunciphisa: Ubunzima obufanele bukhuthaza ukunciphisa okusebenza kahle, okubalulekile ukuze kube nokuzinza.

Izici Eziphakathi KweDensity YeGravel

Izici eziningi zingathinta ubunzima beglayi be-20mm:

1. Ukuhlanganiswa Kwempahla: Uhlobo lwezintaba ezikhiqiza ithafa (isb., i-granite, i-limestone) kuthinta umthamo wayo.
2. Umswakama: Umsebenzi wamanzi ungashintsha isisindo nesikhala se-gravel.
3. Izinga Lokuhlanza: Izinga lokuhlanza elisetshenzisiwe ngesikhathi sokufakwa lithonya ubukhulu bokugcina.
4. Iphuzu lokungena: Isikhala phakathi kwezicucu zegravel ezihlukene sithinta ubukhulu jikelele.

Ububanzi Obufanele Bokuhlukaniswa Kwe-20mm Gravel

Imigomo Ejwayelekile

Ibanga elingcono lokuhlushwa kwe-gravel engu-20mm emisebenzini yokwakha ngokuvamile liphakathi kuka-1,500 kg/m³ no-1,800 kg/m³. Leli banga liqinisekisa ibhalansi phakathi kokuzinzile kwezakhiwo kanye nekhono lokukhipha amanzi.

Izinhlelo Eziqondile

• Ukwakhiwa Kwezemigwaqo: Ngezinhlaka zemigwaqo, kuthandwa ubuqiniso obuseduze nomkhawulo ophezulu (1,800 kg/m³) ukuze kusekwe izikhwama ezinzima zokuhamba.
• Izinhlelo Zokuphumelela: Ezinhlelweni zokuphumelela, ungamukela ukuncipha kancane kokuphakama ukuze ubandakanye ukuhanjiswa kwamanzi.
• Iziqalo: Ekwakheni izisekelo, ukufinyelela emqoka wokuhlala ngaphakathi kwendawo efanele kubalulekile ukuvimbela ukuhamba phansi nokuqinisekisa isikhathi eside.

Uphenyo lwezinga eliphezulu lokuhlala.

Ukufeza ubukhulu obuphakeme be-20mm gravel, cabangela lezi zinyathelo ezilandelayo:

5. Ukukhetha Izisetshenziswa: Khetha ithayela eliphezulu elinokuhluka okufanele nokuwa okuncane.
6. Ukulawulwa KweMvula: Bheka futhi ulungise izinga lemoisture ukuze kube lula ukuhlanganiswa ngaphandle kokwengeza kakhulu.
7. Izindlela Zokuqhubekisa: Sebenzisa imishini efanele yokuhlangana, efana nezithuthuthu ezivibra noma ama-plate compactors, ukuze uthole ubukhulu obufanelekile.
8. Ukuhlola Nokujwayelekile: Qhubeka nokuhlola ubukhulu, njengeProctor test, ukuze uqinisekise ukuthi ibanga le-density elifunekayo lihlangatshezwana.

Isiphetho

Ukufeza ibanga eliphezulu lokuphakama kwesihlabathi se-20mm kubalulekile empumelelweni yezinhlelo zokwakha. Ngokwazi izici ezithinta ubukhulu besihlabathi nokusebenzisa izindlela ezinhle zokucindezela nezokuhlola, ochwepheshe bokwakha bangaqinisekisa ukuthi amaphrojekthi awo akhiwa phezu kwesisekelo esiqinile. Lokhu akukhulisi kuphela ukuvikeleka kwesakhiwo kodwa futhi kwandisa impilo yesakhiwo.

• Ngaphambilini:Ubukhulu bempahla buphazamisa kanjani ukusebenza kwemiphongolo engu-40mm eyodwa osayizi ekwakheni
• Okwesibili:Indlela yokubala Ukwenza Ukuguqulwa kweDensity kweMixes yeSand-Cement-Gravel (tonne/m³)
