Ulwazi lokuthi ungqimba lomhlaba luba khona ngokujulile kangakanani ngokubaluleke kakhulu ezindaweni ezahlukahlukene, kepha ikakhulukazi ekwakhiweni. Cabanga ukuthi leli nani lincike kanjani ekubalweni kwalo okunqunywa ngayo, kanye nobukhulu benhlabathi ebabazekayo kungqimba eliphakathi nendawo.
Kuyini ukujula kwe-primer yenhlabathi?
Ukujula kwe-primer yenhlabathi (i-GPG efushanisiwe) kuyipharamitha ekhombisa izinga leqhwa lenhlabathi yenhlabathi ebusika. Kuya ngezici eziningana futhi kusungulwe ekubonweni kwesikhathi eside kwesifunda esithile. Ukujula lapho izinga lokushisa lomhlabathi likhuphuka ngenhla kwe-zero of degrees, kubhekwa njengephuzu lokuqalwa kwenhlabathi.
Iqiniso elihehayo: emazingeni okushisa ama-minus, akuwona inhlabathi uqobo, nomswakama (amanzi aphansi), okuqukethwe kuwo. Ukuphuma ngaphandle koketshezi esimweni esiqinile, kukhuphuka ngenani ngo-10-15%, okuvusa inkanuko okuyingozi ezintweni zokwakha - inhlabathi.
Izici eziphambili ezithinta i-GPG:
- uhlobo lomhlabathi;
- lokushisa komoya;
- izinga lamanzi angaphansi komhlaba;
- ukuba khona kwezimila;
- Ukushuba kwesembozo seqhwa.
Izinhlobo eziningana eziyisisekelo zenhlabathi zihlukaniswe, kulowo nalowo ohlekisayo okhethekile ochazwayo:
- Isihlabathi esikhulu - 0.3;
- Isihlabathi se-Bulk, sandy - 0.28;
- Inhlabathi ye-burglary - 0.34;
- UClay neSuglinki - 0.23.
Lapho kukhula iqhwa nezimila ensimini, umhlaba omncane ugcinwe ngaphansi kwawo. Futhi inciphise i-GPG ngaphansi kwezakhiwo ezifudumele ebusika.
Ungawabala kanjani?
I-GPG yezifunda ezahlukahlukene ibhekwa njengenani elijwayelekile futhi lalichazwa ngaphambilini kumadokhumenti. Kodwa-ke, ingabalwa ngefomula: DF = D0 + √m, lapho i-DF ingukujula kweqhwa, i-D0 yinqwaba ye-coeffing, MT - isamba samazinga okushisa aphakathi kwanyanga zonke. Le fomula ikuvumela ukuthi uthole i-GPG ngaphandle kokucabanga izinto ezahlukahlukene ezingaba khona ebusweni.
Kulokhu, ifomula eline-parameter eyengeziwe - i-KH isetshenziswa. Lokhu kungukusebenzisana okususelwa kwizici zesakhiwo sesakhiwo kanye namazinga okushisa ajwayelekile nsuku zonke kuwo. Ifomula ithola ifomu elilandelayo futhi libonisa ukujula okulinganiselwe kokuqandeka: DF = D0 + √ndx x KH.
Ngesikhathi sencazelo yokubukwa kwe-GPG okulawulayo kwezwe kwenziwa okungenani iminyaka eyi-10. Ngasikhathi sinye, ezinye izinto azinakwa. Ukujula kwangempela kwama-drainage kuvame ukwehluka ekulawuleni ngo-20-50%. Ngakho-ke, ngokushesha ngaphambi kwemisebenzi, kunqunywa ngokubona noma kusetshenziswa idivaysi ekhethekile.
UMurlotomer uyi-tube ene-hose ngaphakathi, egcwele amanzi, nokumaka kwamasentimitha. Idivayisi icwiliswe enhlabathini ekujuleni kokulawulwa bese ishiya lapho amahora angu-12. Izinga le-Ice likuvumela ukuthi uthole iziphetho ngobukhulu bengqimba eqandayo.
Ukujula kokuqandisa kwenhlabathi ngesifunda
Njengoba iRussia itholakala ezindaweni ezimbalwa zezulu zezulu ezinamazinga okushisa ahlukene wonyaka, inhlabathi, izinkomba ze-GPG zihluke kakhulu esifundeni esifundeni. Lonke umkhuba obonwayo yile parameter yanda ukusuka entshonalanga kuya empumalanga.
Ngokusho kwemithethonqubo, ubukhulu obuncane bereker eqandayo buyaphawuleka emadolobheni anjenge-SOCHI, i-Simferopol, i-rostov-on-don, i-kaliningk kanye ne-novosibirsk, i-tywen, njll . - Kusukela ngo-200 kuye ku-270 cm.
Ngokuqondene ne-Middle strip, isimo sezulu sayo sezwekazi elinomqondo onenqwaba yeqhwa, isithwathwa esilinganiselwe, izimila zamahlathi zibangela i-gpg encane. Kuyahluka phakathi kwama-80-150 cm. Isibonelo: I-Moscow - 140 cm, ukhozi - i-130 cm, i-voronezh - 130 cm.
