Zingangenwa beendonga ongaphantsi

Ngokuqhelekileyo, amanzi ingxaki iba yondele kwi off-ixesha, xa inqanaba lamanzi komhlaba efika kwinqanaba eliphezulu ukuba kuba ngabanini ikhaya abaninzi wothuka krakra kakhulu ngohlobo amanzi iwayini. Ukuba zingangenwa iindonga ze ongaphantsi yi ngokwemveli luqala lokufunyaniswa izizathu zokuba kutheni amanzi khona. Iimbangi ezingundoqo ukufuma kungaba: amanzi elidlulileyo wenza engeyiyo okanye ukungabikho ngokupheleleyo, izixhobo zobuchwepheshe isicelo ezingachanekanga, okanye umgangatho ayanelanga.

kwesakhiwo ezimanzi kubangela ilahleko kwindawo esebenza kakhulu. Kusoloko kukho izinga eliphezulu ukufuma, amafu kunye babumbe phezu kweendonga, kwakunye linjengevumba engasi nokuvunda kwaye ngamathontsi. Xa kwendlu emanzi okanye ukugcina ezi mveliso, njengoko ufane nabo ngogwayimbo. Ngaba oko kubuyela ibe kwindawo esebenzayo ukuba umnini uya kusebenzisa ngenxa iintswelo zabo? Kunokwenzeka. Kubalulekile ukuchonga oonobangela lifumile yaye usebenzise izixhobo ezifanelekileyo eziya ukuphelisa igumbi elalana amanzi.

Ukuba baphuke iindonga amanzi elingaphantsi, angavela apho ngamathontsi. Igumbi inokufunyanwa ngaphezulu okanye ngaphantsi kwamanzi komhlaba, ngokulandelelana, umsebenzi wokulungisa kufuneka kwenziwe kuxhomekeke kule. iindlela zingangenwa ezingafaniyo phakathi kwabo kuphela ukhetho izinto, wona lawo asondezwayo kwi emarikeni, kwakunye nomgangatho wabo. Kodwa technology lungelo enye kuphela.

Ukuba zingangenwa iindonga kwesakhiwo kufuneka senziwe ngokupheleleyo ukuba ibekwe ngaphantsi komgangatho ingenzeka amanzi. Ukuba kweli nqanaba liphezulu, ongaphantsi kunokuba amanzi nje. Kubonakala ngokusebenzisa neentanda phantsi neendonga, kule meko sithetha malunga komhlaba ngokwanelisayo nehigh. Kufuneka wenziwe kunye ukhetho oluchanekileyo izinto ezifanelekileyo. Iindonga amanzi kwendlu kule meko yenziwe ziingcali abaqeqeshiweyo. umsebenzi osontelwe kwezobugcisa iquka izigaba ezibalulekileyo:

- ekuqhubeni earthwork zokumba ukuba ongaphantsi umjikelezo oswele ukuba zingangenwa (ngaphandle);

- ukucoca iindonga lwangaphandle eludakeni;

- ekuqhubeni yokulungisa imisebenzi yeendonga lwangaphandle kwigumbi elingaphantsi, kunye amanzi ethe nkqo nethe tyaba kweendonga ekufuneka ibuyiselwe.

Emva koko ufuna ukubeka yokukhupha amanzi kunye kujikelezo olungaphandle kwigumbi elingaphantsi, uya ngokukhawuleza athathe snowmelt kunye namanzi emvula ezindongeni. yamanzi kufuneka wenze kujikelezo wesakhiwo, nto leyo eza kunika iziphumo ezingcono.

Kwigumbi elingaphantsi kukho ezimbalwa ubuthathaka ezininzi - amalungu emboxo ze umgangatho kunye neendonga. Kwiimeko ezininzi, nje ngezi ndawo engena ngokubonakalayo komhlaba. Phambi kokuqala i amanzi lwangaphakathi, kuyimfuneko ukuba yokumpompa amanzi aphume kwigumbi elingaphantsi, ukuba kukho iyafumaneka.

iindonga zingangenwa kwendlu kubonisa ukubuyiselwa uphawu nkqo nkqo. Uhlobo lokuqala lomsebenzi kufuneka wenziwe ukusetyenziswa ezendeleyo, lubricative zokwambathisa izinto. zingangenwa oxwesileyo lwenziwa ngaphezu kwetafile kwamanzi kunye nokusetyenziswa kwezinto wajula nto lesitofu eludongeni phantsi koxinzelelo ngenxa kumaqula kumbiwe ngendlela ethile. Olu hlobo lomsebenzi kufuna iingcali abanezakhono kakhulu, njengoko ifuna ukusetyenziswa kwezixhobo ezizodwa. zingangenwa oxwesileyo ukufanele ingqalelo iqonga nto inzima umsebenzi.

uphumezo eyiyo zonke umsebenzi kuyimfuneko ongaphantsi ziqinisekise ukuba Ngeke kusaba ezimanzi kunye namanzi. Kungenjalo, uluhlu lwemisebenzi ezifunekayo ukuphumeza kwakhona ukuba ludinisayo nje kuphela kodwa imali eninzi kakhulu.
