Jwalo ka mofuta o motjha wa thepa e kopaneng e tenyetsehang, dimmate tse etsang samente di ntse di sebediswa haholo—ho lokisa noka, ho sireletsa matsoapo a tsela, ho kenya diforo, le merero ya tsosoloso ya morafo—ka lebaka la melemo ya tsona e ikgethang: “ho hlwekisa ka metsi, ho kenya ka potlako, le ho se keng ha kena metsi ka nako e telele.” Ho netefatsa tshebetso e phahameng ka ho fetisisa ya sehlahiswa, Shandong Hongyue Environmental Engineering Co., Ltd. e sebedisitse dilemo tsa tlhahiso le boiphihlelo ba boenjiniere bo sebetsang ho bokella ka mokhoa o hlophisehileng sete ya mekgwa e tloaelehileng ya tshebediso bakeng sa dimmate tse etsang samente. Tataiso ena e shebane le mehato e mene ya mantlha—ho lokisa ka ho nepahetseng ka tlase ho maemo, ho beha le ho tiisa, ho hlwekisa ka metsi, le tlhokomelo kamora ho kenya—ka hona e sebeletsa e le tshireletso e matla bakeng sa boleng ba projeke ka kakaretso.
I. Tokisetso ea Subgrade: Boemo bo Tlase, bo Tiile, 'me ha bo na Lintho tse Bohale le Litšila
Pele ho kaho, sebaka se sebetsang se tlameha ho batalatsoa ka nepo. Tlosa mofoka oohle, metso ea lifate, majoe a bohale le mobu o hlephileng ka botlalo ho netefatsa hore bokaholimo ba mobu ha bo na mapetso kapa likheo. Metheo e fokolang e hloka ho hatelloa kapa ho matlafatsoa ho sebelisoa motsoako oa mobu oa lime (hangata karolelano ea 3:7); moo ho hlokahalang, lera la mosamo oa geotextile le lokela ho kenngoa. Liforo le matsoapo li tlameha ho hlophisoa ho latela gradient e entsoeng; karolelano ea lerapo pakeng tsa 1:1.5 le 1:3 e khothaletsoa ho netefatsa hore metsi a phalla hantle le botsitso ba motheo. Ho kenngoa ka kotloloho holim'a lithōle tse bohale kapa mobu o sa lekanang ho thibetsoe ka tieo ho thibela ho phunya thepa ea materase kapa kabo e sa lekanang ea khatello.
II. Ho Seha le ho Beha: Ho Phutholla ka Boreleli le ho Kopana ho Tenyetsehang
Ho Seha ka Nepahalo: Seha thepa ho latela litekanyo tsa sebaka seo, ho lumella moeli oa ho fokotseha ha 5%, 'me u boloke bophara bo eketsehileng ba 10-20 cm ho ea holimo. Ho seha ho lokela ho etsoa ha thepa e omme, ho netefatsa hore mathoko a sehiloeng a otlolohile ebile ha a na li-burrs.
Tsela ea ho Beha: Phutholla thepa ho theosa leralla, u tsoele pele ho tloha holimo ho ea tlase. Netefatsa hore bokaholimo ba materase bo lula bo atolohile ka tlhaho—bo se na makukuno kapa menahano—'me u qobe ho otlolla ka matla. Bakeng sa merero ea noka le liforo, thepa e tlameha ho beoa ka lehlakoreng leo metsi a phallang ho lona, karolo e ka holimo e koaleha 'me e hatelloa karolong e ka tlase.
III. Phekolo e Tswetswang ke Metsi: Metsi a lekaneng, a tshwanang, le a saense
Tšebeliso ea metsi ke mohato oa bohlokoa o khethollang matla a ho qetela a thepa:
Tekanyetso ea Bophahamo ba Metsi: Tšela bonyane 9 kg ea metsi a hloekileng ka mithara e le 'ngoe (bakeng sa materase a botenya ba 10 mm).
Mokhoa oa ho Sebelisa: Sebelisa sistimi ea ho fafatsa e nang le khatello e tlase ho sebelisa metsi ka ho lekana, ho sebetsa ho tloha mathōkong ho ea bohareng ba materase. Li-jet tse tobileng tse nang le khatello e phahameng li thibetsoe ka thata. Nako ea ho Fola: E fihlela 80% ea matla a felletseng nakong ea lihora tse 24 mochesong oa kamore; e folile ka botlalo kamora lihora tse 72.
Litlhoko tsa Metsi: Metsi a hloekileng a hloekileng a lokela ho sebelisoa; metsi a litšila kapa metsi a letsoai a tla fokotsa boleng ba ho fola.
IV. Ho Folisa le ho Hlokomela: Boloka Mocheso le Mongobo; Qoba Tšitiso ka Tieo
Tšireletso ea Pele: Matsatsing a 7 kamora ho fola, thibela ka tieo sephethephethe sa maoto, mojaro o boima, kapa ho pepesehela metsi a phallang.
Taolo ea Mocheso le Mongobo:
Mocheso o Phahameng (>30°C): Eketsa makhetlo a ho fafatsa ka metsi mme o kwahele ka thepa ya moriti ho thibela ho oma le ho petsoha.
Mocheso o Tlase (≤5°C): Koahela ka filimi ea ho thibela mocheso ho thibela ho hoama le ho hloleha ha thepa.
Tokiso ea Tšenyo: Haeba ho fumanoa likheo kapa masoba, li lokise hang-hang u sebelisa sekhechana se entsoeng ka thepa e tšoanang hammoho le sekontiri.
V. Lithibelo le Litemoso tsa Bohlokoa
O se ke wa etsa kaho ya kantle nakong ya pula; ho pepesehela metsi pele a phekolwa ho tla fella ka ho senyeha ha thepa.
Netefatsa kabo ea metsi e tšoanang; metsi a sa lekaneng libakeng tse haufi a tla fella ka ho fola ho sa fellang ("karolo e tala") le matla a fokolang.
O se ke wa koba thepa ha e ntse e omme, kaha sena se ka baka ho robeha ha faeba ka hare habonolo.
“Bakeng sa likobo tsa samente, molao-motheo ke ‘boleng ba thepa ba 30%, kaho e nepahetseng ea 70%.’ Ho khomarela mekhoa e tloaelehileng ke tiiso ea ho tšoarella nako e telele,” ho boletse Motsamaisi oa Tekheniki oa Shandong Hongyue Environmental Technology. Khamphani e ikemiselitse ho fana ka tšebeletso e felletseng, ea ho tloha qetellong ho isa qetellong—ho tloha phepelong ea thepa le tataiso ea tekheniki ho ea mererong e qaqileng ea kaho—ho nolofatsa ts'ebetso e sebetsang hantle le ea boleng bo holimo ea merero e fapaneng ea boenjiniere.
