Ulwimi
Umthengisi wezixhobo zokwakha izisombululo zoomatshini bokwakha kangangeminyaka engama-30.
Nantsi imeko eyenzeka kwiindawo zokwakha rhoqo kunokuba umntu ethanda ukuyivuma: umsele uzaliswe kwakhona, umphezulu uyabuyiselwa, abasebenzi bayapakisha, kwaye emva kweenyanga ezintandathu kuvela umgca otshonayo ecaleni kwendlela yokusebenza. Indlela iyawa, umthengi uyafowuna, kwaye ngequbuliso wonke umntu uzama ukufumanisa ukuba ngubani owenze loo nto. Impendulo enyanisekileyo, uninzi lwexesha, kukuba akukho mntu wenze nantoni na engalunganga kakhulu - bathathe nje ukuxinana kwe-backfill njengento yokugqibela endaweni yenyathelo lolwakhiwo eliyiyo ngokwenene. Esi sikhokelo sikhona ukulungisa loo ngcinga, kuba ukufumana ukuxinana kwe-trench ngokuchanekileyo akunzima xa sele uqonda okwenzekayo phantsi komhlaba kwaye kutheni inyathelo ngalinye libalulekile.
Ezona zinto zimbini zixhaphakileyo zokuhlaliswa emva komsele zizinto ezizaliswayo ezimbi kunye nokuxinana okunganelanga. Ukuxinana okunganelanga kulula ukukubona kwaye kudla ngokubanjwa kwangethuba. Ukuxinana okunganelanga kuyafiphala — umphezulu ungavakala uqinile ngokupheleleyo ngelixa indawo exineneyo ingaphantsi kwenqanaba, ilinde ngokuzolileyo umthwalo wezithuthi okanye ixesha lemvula ukuba libangele ukuwa. Xa iphela, ayihambi yonke ngaxeshanye. Itshona kancinci kancinci kuloo mgca we-telltale olandela umgca we-trench ngokugqibeleleyo, yindlela abahloli abazi ngayo kanye into abayijongileyo.
Indlela yesibini yokusilela ayibonakali kangako kodwa inzulu ngakumbi ngokwesakhiwo. Imibhobho eguquguqukayo — i-PVC, i-HDPE, intsimbi erhabaxa — ixhomekeke kumhlaba ojikelezileyo ukuze inike inkxaso ecaleni. Xa izinto ezijikeleze umbhobho zingaqiniswanga kakuhle, umbhobho uyatshintsha xa uthwele umthwalo othe nkqo. Inxalenye yawo enqamlezileyo itshintsha ukusuka kwisangqa ukuya kwi-oval, uxinzelelo lodonga luyanda, kwaye ngokuhamba kwexesha umbhobho uyaphela ngaphambi kobomi boyilo lwawo. Awuyi kuyibona le de kube kuhlolwe ikhamera okanye, okubi ngakumbi, ukudilika. Nasiphi na isiphumo siquka incoko enzima kunye nokwembiwa okubizayo.
Eyona nto ibalulekileyo kwindlela yokuzalisa umngxuma kukuyeka ukucinga ngomngxuma omkhulu wokuzalisa uze uqale ukuwucinga njengeendawo ezintathu ezahlukeneyo ezibekwe phezu kwenye. Indawo nganye inemisebenzi eyahlukeneyo yolwakhiwo, iimfuno ezahlukeneyo zokuxinana, kwaye kwezinye iimeko, izixhobo ezahlukeneyo. Ukuzinyanga zonke kulapho iingxaki ezininzi zokuxinana ziqala khona.
Umaleko webhedi uhleli ngqo phantsi kombhobho — ngesiqhelo i-intshi ezi-4 ukuya kwezi-6 zezinto ezibekwe ngononophelo ezinika umbhobho indawo efanayo, esasaza umthwalo ukuze uphumle kuyo. Le ndawo ayixinene nezixhobo zamandla. Ifakwa ngesandla kwaye ixinywe kancinci, kuba into ozama ukuyiphepha kukulayisha indawo phantsi kombhobho wepayipi. Izinto ezixhomayo, ezizaliswa ukusuka kwibhedi ukuya kumgca ophakathi wombhobho kumacala omabini, yindawo yenkxaso esecaleni — mhlawumbi yeyona ndawo ibalulekileyo ngokwesakhiwo somsele wonke. Sebenza apha nge-rammer elula egcinwe ubuncinane ii-intshi ezili-12 ukusuka eludongeni lombhobho, ixinywe ngononophelo ngaphandle kokuvelisa amandla okuchaphazela anokutshintsha umbhobho okanye wonakalise amalungu awo. Zinike ixesha lakho kule ndawo. Yonke into engaphezulu ixhomekeke ekubeni yenziwe ngokuchanekileyo.
Ukusuka malunga ne-12 intshi ngaphezulu kombhobho ukuya malunga ne-18 intshi ngaphantsi komphezulu ogqityiweyo kulapho umgudu wokuxinana uhlala khona ngokwenene. Uninzi lweenkcazo zeprojekthi zifuna i-95% ye-Standard Proctor density (ASTM D698) kule ndawo yokuwela iindlela, kwaye elo nani lithetha into ethile - ayinakubonwa ngamehlo okanye iqikelelwe ngokuziva. Kulapho i-tamping rammer ifumana khona indawo yayo, ngakumbi kwimisele emincinci ezaliswe ngumhlaba wendalo odibeneyo. I-baseplate yayo encinci ingena ecaleni kombhobho ngaphandle kwedrama, amandla ayo okuchaphazela angena ngokuthe nkqo kwi-lift nganye, kwaye isebenza kwi-dollar-dominant fill ngendlela oomatshini abasekelwe kwi-vibration abangenakuyifanisa. Ukuba wakha wazibuza ukuba kutheni ukukhetha izixhobo kubaluleke kangaka kumsebenzi we-trench ngokukodwa, le yindawo echazayo. Ukuze ufumane inkcazelo epheleleyo yokuba xa i-rammer isebenza ngcono kune-plate compactor - kwaye xa ingasebenzi - [isikhokelo sethu kwi I-Rammer vs. Compactor: Ukutyhila umahluko ophambili ] igubungela isigqibo ngokweenkcukacha.
Icandelo eliphezulu — i-intshi ezili-12 ukuya kwezili-18 zokugqibela ngaphambi kwesiseko esingaphantsi okanye umaleko wendlela — kulapho iimeko ekugqibeleni zivuleka khona ngokwaneleyo ukuba kungeniswe i-plate compactor, ingakumbi ukuba ububanzi bomsele buvumela oko kunye notshintsho lokuzalisa kwizinto ezifakwe ngaphakathi okanye isiseko sendlela. Isantya kunye nokugubungela umphezulu kuba luncedo ngakumbi apha kunokungena kwempembelelo enzulu. Iipaseji ezimbini ezithe nkqo ezine-reversible plate compactor kwi-final lift yeyona nto incinci. Musa ukuyinqumla le ndawo kuba nje ikufutshane nomphezulu — ithatha umthwalo wendlela othe ngqo, kwaye ngumaleko obonisa ukuhlala kuqala.
Ukuba kukho umthetho omnye owahlula amaqela angaphumeleli rhoqo kwiimvavanyo zokuxinana kumaqela angaphumeleliyo rhoqo, ngulo: sebenza ngokuphakamisa okuncinci kwaye ubale yonke ipasi. I-rammer esebenza ngokugcwalisa okudibeneyo kufuneka isebenze kungabi ngaphezu kwe-8 ukuya kwi-10 intshi yezinto ezikhululekileyo ngokuphakamisa ngakunye. I-plate compactor kwi-granular fill ifikelela phezulu kwi-6 ukuya kwi-8 intshi ngokuphakamisa ngakunye phantsi kweemeko ezininzi zendawo. Ukuzama ukuxinana ukuphakanyiswa kwe-14-intshi ngexesha elinye kuvelisa umbono othembekileyo - umphezulu uyaqina, yonke into ibonakala ilungile, kwaye isiqingatha esisezantsi sokuphakanyiswa asizange sichukunyiswe ngamandla okuxinana abalulekileyo. Loo maleko ungaxinananga yimeko elindele ukwenzeka.
Inani labadlulayo alikho nje ngokwesiqhelo. Isiseko somsebenzi omninzi womsele ohambelana nemigaqo kukudlula okuphindwe kabini ngokuphakamisa nge-rammer, okanye ukugqitha okubini okuthe nkqo okune-plate compactor. Kufuphi neendawo zokunqumla iindlela ezinodaka olunzima, ukugqitha okuthathu kusisiseko esikhuselekileyo. Ngaphaya koko, ukugqitha okongezelelweyo kuvelisa imbuyekezo enciphayo xa izinto zifikelele kwinqanaba elifanelekileyo leProctor - kwaye ukutyhala ngaphaya kwelo nqanaba kumhlaba odibeneyo kunokubangela ukungaphumeleli kokucheba endaweni yokuxinana ngakumbi, okufana nokuxinana okufana nokuqinisa ibholiti.
Umhlaba uqina kakuhle kakhulu kumxholo wawo wokufuma ofanelekileyo okanye okufutshane nawo - ngesiqhelo malunga ne-13 ukuya kwi-15 yeepesenti zokuzalisa okwenziwa ludongwe. Ngaphantsi kolo luhlu, amasuntswana omhlaba ayamelana nokulungiswa kwakhona nokuba umatshini wenza amapasi amangaphi. Ngaphezulu kwawo, oku kuzaliswa kuba yiplastiki kwaye kutyhala ecaleni endaweni yokuxinana ukuya ezantsi, nto leyo enye yeendlela imibhobho esuswa ngayo. Ngokwenyani, oku kuthetha ukujonga ukufuma okuzaliswayo ngaphambi kokuba kungene ukuphakanyiswa kokuqala, ingakumbi xa usebenzisa izinto zendalo ezimbiweyo ebezihleli kwinqwaba yezinto ezibolileyo kwimozulu eguquguqukayo. Okuzaliswa okumanzi okubonakalayo, okunamathelayo kufuna ixesha lokukhupha amanzi okanye kufuneka kufakwe umoya ngokusasaza nokujika ngaphambi kokuba kuqale ukuxinana. Ukongeza amapasi amaninzi ekuzalisweni okumanzi akuthathi indawo yokulinda - kuchitha nje ixesha kunye namafutha ngelixa umhlaba uhleka umatshini.
Ijiyometri yomsele isusa uninzi lwezixhobo zokuxinana ngaphambi kokuba ufikelele kwingxoxo yohlobo lomhlaba. Imisele eqhelekileyo yokusebenza isebenza ububanzi obuyi-18 ukuya kwi-36 intshi, kwaye xa kukho umbhobho osembindini, indawo yokusebenza incinci. I-plate compactor ibanzi kakhulu kwiimeko ezininzi kwaye ayinandlela yokujikeleza iindawo zokudibanisa imibhobho okanye izixhobo ngaphandle kokubeka emngciphekweni umonakalo. I-baseplate encinci ye-rammer - eyi-11 ukuya kwi-13 intshi kwiimodeli ezininzi - ingena kakuhle ecaleni kwendawo yombhobho, kwaye ukuma okuthe nkqo kokusebenza kuthetha ukuba umatshini unokulawulwa ukusuka kumphetho womsele ngaphandle kokufaka umqhubi kwindawo yokwemba.
Kwi-fill yendalo edla ngokwenziwa ngodongwe, eyona meko ixhaphakileyo xa kusetyenzwa imijelo yasezidolophini, i-percussive impact ye-rammer ikwasisixhobo esifanelekileyo sezinto ezibonakalayo. Amasuntswana odongwe ayadibana nge-chemistry yomphezulu, hayi ukungqubana, kwaye awaphenduli ngendlela ecacileyo kwi-vibration. Afuna amandla okubetha ngqo ukuze akhulule umoya namanzi avalelekileyo kwi-matrix yomhlaba. Oku kanye yi-rammer ekwenzayo - kwaye kanye kanye oko i-plate compactor engenako ukukubonelela ngokuthembekileyo kwizinto ezidibeneyo.
Ukuva umhlaba ngesihlangu sakho akuyonto yovavanyo lokuxinana. Luqikelelo nje. Iindlela ezimbini zasentsimini ezikwirekhodi yeprojekthi yi-nuclear density gauge (ASTM D6938), enika ukufundwa koxinano olukhawulezayo kunye nokufuma kwindawo, kunye novavanyo lwesanti cone (ASTM D1556), olucothayo kodwa aludingi zixhobo zilinganisiweyo ngaphandle kwezixhobo ezisisiseko zesiza. Zombini zibonisa iziphumo njengepesenti yoxinano oluphezulu lweProctor. Kwindawo ephambili yokubuyela umva, uninzi lweendlela kunye neenkonzo zifuna i-95% yeStandard Proctor. Ngaphakathi kwi-12 intshi eziphezulu phantsi kwendlela, i-98% yeyona mfuneko iqhelekileyo.
I-cadence yovavanyo olusebenzayo lokuwela iindlela yindlela enye yokuvavanya uxinano ngeenyawo ezili-100 zomsele nge-lifti nganye, kunye novavanyo olunye ngotshintsho lwe-lifti nganye kumsebenzi ohloliweyo. Ukuba uvavanyo lubuya ngaphantsi kwe-spec, sebenzisa ezinye iipasi ezimbini kwaye uvavanye kwakhona ngaphambi kokubeka i-lifti elandelayo. Ukongeza ukugcwalisa ngaphezulu kwizinto ezingaxinenanga akusombululi ingxaki - kuyayingcwaba, kwaye ekugqibeleni umphezulu womhlaba uya kuyifumana.
Ukukhetha umatshini wokuxinanisa ofanelekileyo sisigqibo sokuqala, kwaye ukuwenza gwenxa kuchaphazela yonke into elandelayo. Ukuze ufumane inkcazelo ecacileyo yokuba kufuneka usebenzise nini i-tamping rammer xa kuthelekiswa ne-plate compactor — kuquka uhlobo lomhlaba, ubunzulu bokuphakamisa, i-geometry yendawo, kunye neendleko — funda isikhokelo sethu esipheleleyo: [ I-Rammer vs. Compactor: Ukutyhila umahluko ophambili ].
