Ukwandiswa udongwe: uxinano, ubunzima, iimpawu kunye nesicelo

ngodongwe eyandisiweyo, ogama ukuxinana kufuneka azise nawuphi na intsimi zobungcali inkosi yayo, ngubani ofuna ukuthenga izinto malunga naluphi na uhlobo lomsebenzi, izenzo njenge usambathisa indalo. Le ukwambathisa bubonakaliswe granules misindo ezo zifunyenwe kwinkqubo ngokudubula udongwe yi indlela ekhethekileyo. Inkqubo ye nokudalwa ngodongwe eyandisiweyo yahlulwe kwizigaba eziliqela. Ekuqaleni, nkcwe ngodongwe, yancedwa umvumbo nobushushu elibukhali. Oku kukhokelela ukuyilwa granules misindo. Inxalenye engaphandle inyibilikiswa, okwenza izinto kangangoko kunokwenzeka oluzinzileyo ngamandla kuzo zonke iintlobo iimpembelelo banqande.

Iimpawu eziphambili

Xa uba wazi, njani na imveliso ngodongwe eyandisiweyo, ungasa kwi ekufundweni iimpawu ezingundoqo eziphathekayo. ukumelana frost, nasekugxotheni ukufuma iimpawu zabo babefanele bahlule phakathi kwabo, uqinile, umlinganiselo kangangoko iindleko nomgangatho, kwakunye namandla eliphezulu.

Le nto ke kwakhona ukwenzela ukuphucula isandi kunye nokugqunywa kobushushu iimpawu yokwakha. Ukuqwalasela i ibloko eziphathekayo, lexinene ziza kukhankanywe apha ngasezantsi, kufuneka sinikele ingqalelo kwakhona yokuba oko anazo inertness imichiza. Le nto ayikho woyika impembelelo lomlilo, kwaye alikwazi ibe yindawo apho ukubola ziya kwenzeka. Nangona kunjalo, akukho mfuneko ukukholelwa ukuba izinto zokwakha iqulathe kuphela zokugqwesa.

ukushiyeka

Nangona iindleko ngodongwe eyandisiweyo kwamkelekile kakhulu phakathi iimpawu zayo kukho HIV, ngenxa athi ngamanye amaxesha inkosi uyala ukuba uthenge le yokugquma, ukukhetha ezinye izifudumezi. Oku kungenxa ubu ezi iingqalutye, njengoko neengcali kunye olungisa kufuneka siyikhumbule xa egcwalisa. Phakathi kwezinye izinto, udongwe eyandisiweyo kungcono kusetyenziswa kuphela backfill owomileyo. Granules ithambekele ukufunxa ukufuma kwemfuneko, ngokuthe ngcembe yome.

izakhiwo

Njengoko yokusebenza ibonisa, ulwakhiwo ngezitena cozier kuthelekiswa izakhiwo eziphathekayo. Clay, leyo ngexesha imveliso ijongene unyango olufanelekileyo, kunokuba umqhubi kakuhle ubushushu nengqele. Building ngodongwe eyandisiweyo uye iipropati ezifanayo ngenxa kulwakhiwo lwalo amazwe. Kodwa ukuba uza ukusebenzisa isifudumezi njengoko bulk yokugquma, kufuneka ulumkele conductivity yayo thermal. Ngenxa yale nto ke malunga 0.12 W / Km. Nakuba kunjalo, kufuneka sikhumbule ukuba ubungakanani granules inokuba nomahluko.

Kodwa oku zonke iimpawu ukuba ufanele wazi phambi kokuba baqalise umsebenzi. Umzekelo, kubalulekile ukuba uthathe ingqalelo lexinene. Xa siqhuba uvavanyo ucinezelo, oko kwazeka ukuba i-13 pesenti umthamo itshabalele. Oku kukuvumela ukuba maleko uphawu olongezelelweyo.

Ache Weight

ibloko eziphathekayo, lexinene oluno ezahlukeneyo, zohlulwa ngokwendidi eziliqela. Ukuba kuluphawu M-450 kwi iqhezu 10-20 mm, lexinene eziphathekayo ngomgubo wengqolowa obunzima buziikhilogram 440 nge-cubic meter. Nangona grade M-500 onokuxinana kilograms 465 nge-cubic meter.

Kodwa umgangatho ngodongwe eyandisiweyo zixhomekeke uhlobo amaqhekeza. Le zithutha kufuneka imilo asondezwe, yaye inxalenye engundoqo kufuneka isuswe ngu umgama ngokulinganayo.

Kubalulekile ukwazi ukuba yintoni na ubunzima nodongwe eyandisiweyo. Umthetho-siseko kuku kugqalwa isibonisi 0.95 grams nge-cubic meter. Ngexa mninzi bulk liya kuxhomekeka kwizinto eziliqela, apha kufuneka kwaziwe nokuba ubukhulu okuziinkozo. Ngokomzekelo, omnye cubic meter eziphathekayo, inxalenye yazo apho iimillimitha-30, uya nobunzima malunga 340 kilograms.

Ububanzi bokusebenzisa

Xa ukhetha le zokwakha echazwe kubalulekile nje ubunzima ngodongwe eyandisiweyo, kunye nezinye iimpawu. Nakuba kunjalo, kufuneka ukubona ngaphambi kokuba uthenge ukuba oku ubushushu kwindawo ethile. Ngophanya nje lweliso, kusenokubonakala ngathi ukuba imihlaba ayikho nje ebanzi, kodwa granules ezineefitsha ubushushu-saving elihle ekuvumela ukuba usebenzise imbawula ekuzalweni okutsha ngayo imigangatho, kwindawo ephantsi kophahla nakwiisilingi. Kufuneka kuqatshelwe ukuba ubushushu kule meko nakanye omncinanana iipropati luncedo.

ngodongwe eNatyisiweyo, lexinene leyo okhankanywe ngentla, lisetyenziswa umaleko ngxabano. Ngokucace kakhulu, oku kusetyenziswa njengesiseko lokusekwa screed eziphathekayo. Phakathi kwezinye izinto, le granules ingasetyenziselwa ukulahla isiseko ngethuba umsebenzi wokwakha. Ngokusebenzisa ngodongwe eyandisiweyo kunokwenzeka ukuba kunciphisa ubunzulu onomtsalane ekubekeni isiseko, maxa wambi amanani kungancitshiswa ngesiqingatha. Ngenxa yoko, uyakwazi ukugcina izinto zokwakha, kwakunye ukuphelisa qhwa komhlaba kufutshane kwisiseko.

ngodongwe eYandisiweyo idla ngokusetyenziswa ngexesha lokwakha ehomereni ke, apho kukho imfuneko yokuba i ngokomgangatho unombombiya iindonga osezantsi. Nge zithutha uyakwazi ukufikelela kubushushu ethile ekufuneka egcinelwe ixesha elithile. Kwimeko ingozi umnikazi wendlu akuthethi kujongana imfuneko dig yonke indlela.

Enye inzuzo izenzo, emva kokuba ukulungisa eziphathekayo block anokuphinda asetyenziswe, ukanti kuphulukana iimpawu zayo. izinto zokwakha echazwe ngogqibeleleyo ukuze kudalwe iindlela egadini okanye inkqubo yokukhupha amanzi, nto leyo uya kukhokelela ekwandeni kwemveliso. Ngenxa imfuneko esisiseko kulo mzekelo isebenza ukusetyenziswa granules omncinane.

Iindleko zokufunda

iindleko keramzita ivuleleke kakhulu kwi-avareji kumthengi. izinto Ixabiso liya kuxhomekeka iqhezu. Umzekelo, amanqaku M-650, nto leyo ebonisa ukuba ubukhulu granular kuluhlu-5 eemilimitha, into engange 96. bag omnye, lo gama yayo iya kuba 0,035 cubic meter. Ngokwandisa noqhekeko ukuya milimitha 10 ixabiso liye lancitshiswa engange ngengxowa 85, ingxowa liya kuba omnye umthamo 0.04 cubic metres.

iqhekeza ezibonakalayo

Ukuba ugqiba opt ukwakhiwa ibloko eziphathekayo, iqhezu le nto, kufuneka ucinge ngaphambi komhla lokuthenga. Izilinganiso granules zixhomekeke iintlobo eziphathekayo. Umzekelo, isanti, udongwe eyandisiweyo ineenkalo ngezinto ngaphakathi ngemilimitha-5. Ngokumalunga umxube intlabathi-igrabile, iqhezu yayo kwandisa ukuya ngemilimitha-10. Nangona kwandiswa igrabile lodongwe inokuba izinto ubungakanani-10 ukuya ku-20 iimilimitha.

ukusetyenziswa

ukusetyenziswa ngodongwe EPWP kufuneka ibalwe ngamnye. Amaninzi le nto kusetyenziswa ekuzalweni okutsha kwamaqhina. Ngoko ukuba ingaba isentimitha layer kuya kufuneka ukuchitha malunga 0,01 cubic metres square metre nganye. Ezinye iivenkile keramzit wakhululwa iilitha. Kulo mzekelo ukudala cm inwebu ngodongwe eyandisiweyo kwi screed kuya kuba yimfuneko iilitha ezili-10 square metre nganye.

isiphelo

ngodongwe eyandisiweyo, iqhezu yinto luphawu ebalulekileyo yale zokufunda zingasetyenziswa zonke iintlobo zemisebenzi. Ukuze kuphunyezwe ziphumo zinqwenelekayo, kuyimfuneko ukuba ukukhetha ubukhulu lasekunene zithutha wabeka izinto kubuxhakaxhaka.
