Trenchless yokubekwa kwemibhobho: Inkcazo Indlela

Ithekhinoloji umbhobho trenchless ngokubekwa apho ixesha elide. Buyela kwi 80s ye pipelayers kwinkulungwane yokugqibela usibeke kumbhobho yokukhupha amanzi emhlabeni. Kunokuba ukumba nezisele mechanism lisikwe emxinwa, yaye apho efihliweyo cable okanye emanzini.

Namhlanje kwabonakala isixhobo, ehlahla amakhulu kweemitha yemibhobho phantsi komhlaba ngokupheleleyo ngaphandle lokuvula emhlabeni. Ezo Spetstechnology ukudlula iindleko ezenziwe yi umthengi konga ixesha nemali.

ukhetho inzuzo

Trenchless ezifunekayo kwiimeko ezimbini: xa ngokufaka umbhobho esitsha esiya kuthatha indawo ayiphumelelanga okanye endaweni yonakele, ivalekile mome endala.

Ukuze ube umbhobho entsha ngokupheleleyo iye enyanyeni endala akathi na umgama efunekayo kutshiphu kakhulu kunokuba agrumbe, ukuncothula i ezonakeleyo bebeka entsha.

Ingakumbi indlela entsha ingqokelela uba ezifanelekileyo kwiindawo ezisezidolophini apho kungekho zobuqili ngexesha imisebenzi ehambelana iindleko ezinxulumene ne kwimingxuma yamanzi aphilileyo, kwaye kunzima kakhulu ukwenza le ngxaki ukuhamba kwezithuthi nje wawumkhulu.

pipe Trenchless yenza kube lula ukufaka phantsi iindlela, ingca, iindidi kumaqonga, hayi angatshabalalisi.

Ukubeka ubukhulu umbhobho ezincinane phakathi endala

Le ndlela ilula kwaye ibiza ukufakwa trenchless. Ngokuqhelekileyo, umsebenzi onjalo oluqhutywa phaya koyintloko amanzi akuphumelelanga. Ngaphakathi imibhobho endala olule a polyethylene entsha. Smooth udonga iplastiki permeability vodopotoka ukuba iiplastiki aziwuthi.

iimveliso polyethylene omzimba yokungafani ubushushu enkulu, anikho phantsi inkqubo umhlwa. Bathi ke ukukhanya, kulula obandayo, zexabiso eliphantsi. ubomi babo ngabantu angaphezulu ubomi kwemibhobho Yamxuluba-yentsimbi. Ba iplastiki, goba lula, nto leyo ebalulekileyo xa usebenzisa ubuchwepheshe obutsha.

pipe Trenchless usebenzisa sokutsala into ngentambo lumi ngolu hlobo lulandelayo:

1. A iqhekeza ibhityile umbhobho ndimaphule kwiindawo ezimbini.
2. Kwenye amanqaku kakhulu lula emibonweni imvelaphi inyuselwa sokutsala into ngentambo.
3. Le umbhobho lilungiswe yonke ubude isabhokhwe ayegqatse intambo.
4. Ukusebenzisa into ngentambo kunye umgca nguyá ekhethekileyo zalungisa of ungcolisa kunye dipozithi Ukwakheka.
5. Emva koko, usebenzisa intambo sokutsala into ngentambo enye liqiniswe ubungakanani Eziniyeni polyethylene.
6. Kuba flanges umbhobho weplastiki aqhotyoshelwe apha kwaye ifakwe vana. Kuyenzeka ukuba unikeze amanzi.

Ngokuba ngoohola, apho amanzi aqukuqela yi womxhuzulane (imisele, egobile komisa nantoni) imibhobho Yokutshayelela lwenziwa ukusuka kwindawo enye. I-pipe ibandla lamaqhosha ezimfutshane kusetyenziswa uqhagamshelwano azinamsonto okanye iimpahla zakhe zokutyhomfa, kwaye njengoko ibandla zityhalelwa ngaphakathi kumbhobho endala.

Ukubeka ityhubhu of sangqa nangakumbi endaweni endala

Le ufakelo pipe trenchless yobuchwephese enzima kakhulu. Kufuneka ube yinxalenye Skena ngesanti kubunzulu baphantsi ukumpompa afakwe ioli.

Le ndlela isebenza ngolu hlobo lulandelayo:

1. Ngokusebenzisa le conduit zeemoto kunye ubude bayo nangengalo intambo.
2. Cable isiginci ngaphezulu komgca Skena le.
3. Emva impompo oyile oya kumanzisa enganyangekiyo ngomtshini Skena ukunyuka koxinzelelo uyakhula ububanzi yaye utyhala kwicandelo duct apho. Broken umbhobho ziba emhlabeni.
4. Uxinzelelo oyile iyakhutshwa, Skena ifumana umthamo lokuqala kunye sokutsala into ngentambo enziwe isilo enye inxalenye umgca. Kuba Skena irhuqa owabelwa isabhokhwe entsha.

Iinzuzo Yokutshayelela inkqubo entsha yonikezelo lwamanzi ngaphakathi okanye endaweni ezicacileyo akuphumelelanga. iindlela komhlaba olunga- isicwangciso ayitshintshi, akukho sizathu kukungqinelanisa umsebenzi wokulungisa kunye nezinye izakhiwo ukuba mkhulu konga imali kunye nexesha.

Njengokuqhekeka komhlaba shoka ukubetha pnevmoproboynikom

Le ndlela ipipi trenchless ngokubekwa usebenzisa iteknoloji ngesando elula. isiguquli, umoya isigodlo kulo nethumbu. Kunye ivelufa ulawulo , umoya zixinaniswe uqala lityhale izando nezixholo, omnye umxhelo, okuhamba umzimba zihambe.

Umzimba streamlined ine ubude enomtsalane (kangangeemitha ezi-2 okanye ngaphezulu). Zokuhlatywa osemqoka ukuba pnevmoproboynik ukusuka ezantsi mngxuma zokumba libetha ulwalathiso rectilinear tye. Kakuhle ubunjwe uye iindonga egudileyo.

Kulo ngobuwena, umgca ukunika indlela elungileyo kunzima kakhulu. Nangona, ukuba awuthwale ngenyameko ngaphandle zonke izibalo kuyimfuneko, - kunokwenzeka. Kukho wathumela ayekelele kukothuka-ukubetha. Kodwa ngenxa yeenzima ezithile technical ukuba imveliso eliphantsi.

Ukubeka pipe indlela kwabaqhubi

Olu uhlobo lwe trenchless Umbhobho ngokubekwa wayedla kongaphantsi umhadi. pipe Steel ekupheleni kwayo zityhalelwa emhlabeni. Kwisisu kuyo kwakugcwele emhlabeni. Kamva, umhlaba isuswa umoya okanye iqhosha lemenyu ezizodwa, apho, njengoko nguyá, ococa ngaphakathi mome.

Isebenziselwa ngokucinezela IKONA hydraulic amandla eliphezulu. Loo iyunithi kufuneka inkxaso ngamandla, nto leyo maxa wambi kunzima ukufumana. Ngoko ke, xa iperi IKONA ukuba zisebenze isixhobo vibroimpact utyhala projectile kwi spurts ezincinane.

Loo gasket ndlela ephawulekayo kuba kunokwenzeka ukuba usebenzise isando kweli cala wacela umbhobho enkulu (2,500 mm).

ukubhola zemiyalelo oxwesileyo

Yeyona nto ibiza ukhetho zonke ngasentla. Kodwa kukho inzuzo enkulu. Ezo trenchless yokubekwa imibhobho isetyenziswa xa ezinye iindlela sele ayisasebenzi. Xa usebenzisa olu khetho, unako isimbo imivumbo yakho nkqu eweni.

Enyanisweni, indlela ngokwayo ufana inkqubo ukubhola eqhelekileyo, kodwa kuphela kwicala tye. Izinga sicatshulwa kwingxelo uyahluka 1.5 ukuya ku-20 eemitha ngeyure nganye. Kodwa kule ngobuwena, sebenzisa eqhelekileyo drill ipipi akakwazi. Torque evela injini yadluliselwa esatsiba esebenzisa kwizinti ngokumba ezizodwa, yanamathela yi yeehenjisi.

Ukubhola edwaleni kule nkqubo ibandakanya ukusetyenziswa zokomba udaka. It is a uhlobo ekuthambiseni icandelo okupholisa ukuya drill bit. Isisombululo kwakhona oqondela udonga isitsala, angavumeli ukuba ukusasaza, lo gama ekuncedeni ekupheliseni ifuthe wokugrumba.

Ukuze onesiphumo kakuhle zibandakanya tube entsha. Kodwa inkqubo yokomba iya kuba nganto ukuba indlela equleni iya kuhlangana ulandela komhlaba.

ibanga

Zohlobo lwe omncinci ngokusebenzisa umgca sokutsala into ngentambo eligugileyo azotywe kumgama eemitha 500. Ezinye iindlela trenchless ukuvumela ukuba ukubeka isabhokhwe kumgama oziimitha 40-80. Umsebenzi kuphuhliso obu bugcisa yaqala ukuba wenziwe akunjalo kwakudala, ngoko ke isakhono resource kweeprogram kuphuhliswa omkhulu.

Trenchless neze off ezisetyenziswa imihla ngemihla. Ukuba kukho imfuneko ukudibanisa ukuya indawo yokulala yabucala ubonelelo lwamanzi, kungcono babhenele iinkonzo excavator. Okanye, kwiimeko ezigabadeleyo, umhlakulo oluqhelekileyo. Oku kubangelwa isiphelo iphuma eqolo.
