Ukuthini Ukushintshelwa Kwemigqa? Isihloko Esigcwele Kulokusebenza Kwesiluleko

Umsebenzi wokubhala kwezikhali zomfula Ukuchazwa kunye neempawu eziphambene

Ukushintshelwa kwemigqa ukushintshelwa kwenziwa ngemashini yokululeka yokuthola ngokuzenzekelayo ukusebenzisa amagugu angalungiswa noma amagugu akwazi ukungena kumigqa esetshenziswa ukulahla noma ukulahla amadoda. Le mashini esebenzisa amagugu amagugu, ngokuvamile amagugu a-HDPE, along contours of ditches ukuvikela ukuthibwa kwezimalo futhi uvikele amadoda alula. Ngokuhambelana nekusebenzisa amagugu ngendlela yokwenza, ukushintshelwa kwezimalo kunezindlela zokulayisha amagugu okuqukethwe kakhulu okudingekayo ukulawulwa kwemigomo yemigqa.

Izinto ekuqaleni zinamathilini akhona okuqondisiwe ngokulayisha amarolisa kanye ne-trencher enklini yekhodi yokulayisha amaphoyinti, izinhwele zokupressa ezifanakaliswe, nezimandla zokulandela izindlela (0–45°). Kodwa ukusebenzisa izinhlelo zokulayisha eziguqulwe GPS ikhondla i-frac kusikhundla esingaphezu kwezinhloko, futhi izinhlelo zokuphindeka kwekhodi ziqinisekisa ukuphakama kwekhodi, ngakho ayikho amandla okulayisha amaphoyinti. Lezi zinhlelo manje zokwabelana nazo kuzovelelwa ngekhodi yokulayisha izindlela ezifakwe ngokuzenzekela engenza ukuthatha isikhathi sokufaka kabusho 60% ngaphansi kwezindlela eziqinile.

Izinhlobo Zemashini Zokulayisha Amathilini kuzo

Ukulayisha Amathilini vs. Imithilini Yekhaini

Imashini yokulayisha amathilini isebenzisa amarolisa okulayisha okuyimelwe ukuze kwenywe amathilini aphakeme, okulungile kuzo zonke izinsala eziphakeme. Imithilini yekhaini isebenzisa izikhombisa ezimiselwe, ezifanaye kakhulu nezindlela ezinemali noma ezingenakwekanga ngokuthi zilayishwa ngokushintshashintsha.

Imishini Ebekwe Ngokulayisha Ikhodi Yekhadiwe

Izinhlayiya zokugcinwa kwezimali zinikeza amandla okulinganisa kakhulu kumaqo amakhulu noma kwezimali ezikhulu, ke ngoko kuzenzakalelayo kwezimali ezikhulu njengokwehlukaniswa komoya. Isakhiwo samo yabo anesabelo lokuthi zibe yinhloko yesistimu esivele ikhona.

Izinhlayiya Zokuxhumana Nezimali Ezinkulu

Izinhlayiya zokuxhumana nezimali zinikeza ukusebenza okungena kwezimali (65 dB) nokuthula kwezimali ezikhulu. I-Batteries yezimali ezikhulu zinikeza isikhathi sokusebenza kwezimali kusuka ku-4-6 amahora, ke ngoko kuzenzakalelayo kwezimali ezikhulu.

Ukusebenza kwezinhlayiya zokulayela izimali

Ukukhanya kwezimali Ngokusebenzisa Izinhlayiya Zokulayela Ngokuzenzekelayo

Izinhlayiya zokulinga izimali zilinga ukukhanya kwezimali nokulinga kwezimali kusuku lwesikhathi, zilungisa ukulinga kwezimali nokukhanya kwezimali ukuthola ukusebenza okuningi. Izingxenye zokukhanya kwezimali zilaywa kusuka ku-1.8 mita pansi futhi zilaywa kusuka ku-25–40 cm/min izikhathi zokuthula.

Izinhlayiya Zokulungisa Izikhathi Zokuthula

Izinhlayiya zokuhlanganisa zokwenza izinkomba zokulandela izindlela ezingu-25°–70°, nezinhlayiya eziphakathi ezikubangela ukwehla kwezindlela. Iminclinometer edivayisiwa ikwazi ukuthola ubunzima, ibekela amakhomuni lapho kudingeka. Izindlela eziphakathi kweclay kuxhomekeka emakhanda amakhulu, fela izindlela eziphakathi kwebhakabhaka kudinga ukucindezwa okuncane (<35°) ukuvikela ukuthungatha.

Imigomo yokukhetha Iziphumo ze Mashine Yekhono

Ubukhulu Beprojekthi konke Nokwabiwa Kwezinhlayiya

Iziprojekthi ezingaphansi (<500 linear feet) zinhle ngemathini embalwa (15–25 ft³/min). Izigaba ezikhulu zokulimala kwamanzi (>5 miles) zidinga amakhinye aphakathi (80–120 ft³/min) ukuvikela ukuthwele kwezinsuku.

Imigomo yokuvavanya Uhlobo Lwendlela

• Izindlela eziphakathi kweclay idinga izinhlayiya zokushisa zokwehla komkhiqizo.
• Izindlela eziphakathi kwebhakabhaka/izindlela eziphakathi kwebhakabhaka idinga ukuvikela ukuvutha okuningi.
• Izindlela eziphakathi kwamanzi amakhulu kufanele kube ne-monitoring yangempela ye-density.

Ukuhlolwa okungakwaziwe kwezindzawo kubhabha kwezindleko zokusebenza okungu-68%.

Ubudlelwane Nokwaziyo weOperator

Izinhlayiya zemfanelo eziphambene kudinga amahora we-50–70 wokwaziyo olungile. Izinhlayiya ezine operator etikwaziyo zilayele amaphethini okusebenza futhi kudinga amahora we-31% angaphansi.

ukuncipiswa kwe-30% Kwamaphulela eMississippi

Izinhlayiya zokulayela ngokuzenzekela kwe-2022 Mississippi River Levee project zikhuphela ukusebenza kwabantu kwezingu-30%, ekhuphela amahora wokusebenza angu-12,000. Iyunithi ezinayo i-hydraulic ezenza amamile angu-2.3 ngezinye izinsuku—40% ngokushesha kunezokusebenza ngabantu—futhi zilondoloza ukuphakama kwe-±0.5°. Oku kwenza ukuthathe amakhulu angu-2.7 million ngezinye izinsuku kanye nokungena kwe-850,000 eza kungaphakathi kwezindzawo zokulwa ngenxa yokuphela kwezinye izinsuku ezingu-22 ngaphambi kweqoqo.

Isigaba seBuciko: Ukuzenzekela koma Ukusebenza ngabantu

Kodwa noma kube nguye ukubusa imali yokusebenzisa izilimame nge-30% kanye nokhula isikhathi nge-25%, izindleko ezibalweni ngaphezulu kwe-$200k ngawunithi, kunoma futhi izindleko zokulungisa nokwazi. Kuzindleko ezingaphansi kwezilimame ezifanelwe ukusebenziswa ngendlela yokusebenza ngokwamanje, lapho noma lapho izindleko zezilimame ezingaphansi kungase kungenhloso. Ukusebenzisa ngokweqile ukuzimelela kungase kuthulela ukutholwa kwezimpendulo njengoba kubonwe esikhathini sokuzimelela kwezimali. Indlela Efanisiwe enikeza amandla ukuthi ikhulume kuzindlela ezihlukahlukene.

Imibuzo Evame Ukubuzwa

I-ditch lining machine isebenzelwa yini?

I-ditch lining machine isebenzelwa ukuzimelela ukubekwa kweziliningi ezingayilali kuzindle kubasebenzisa ukuphila komhlaba kanye nokugcina ubushusho bawoti.

Kukhona izinhlobo ezahlukahlukene ze-ditch lining machines?

Yebo, kukhona izinhlobo eziningi, kanye nezilimame zokuxhuma, izilimame ezithunyelwe ngechaini, izinhlobo ezinehambo lokuqinisa, nezinhlobo eziphambene ezinehambo lezinhlobo, ngayinye ihambelana nezinto ezihlukahlukene nezilimame.

Yiziphi izintetho zezilimame zokulayisha izindle ngendlela yokuzimelela?

Lemipemu lawa kulethwa ukunqanda isikhathi, ukuncipha izindleko zokusebenza, ukulaywa kwegazi ngokuphelele, nokhuthaza isikhathi sasekapeni. Kodwa, kuzokwenzeka ukuba nezindleko eziphezulu ngokwesibani.

Imipemu yekhanda iyakontributeka kanjani ekugcineni kwezimalo?

Imipemu isebenza nge-sensors ukulinganisa ukugcina kwezimalo nokungu, ukulandelana nokuqinisa ukugcina kwegazi, futhi ukulaywa kwegridi zokugcina ukunikeza ukugcinwa kwezimalo ngokubalulekile.
