Trenchless kubekwa amapayipi: incazelo Indlela

Ubuciko Trenchless ipayipi ebeka khona isikhathi eside. Emuva ku 80s of the last pipelayers ekhulwini ayifake ipayipi phansi amanzi. Esikhundleni ukumba nezisele indlela umqhewu emincane, futhi lapho ikhebula noma amanzi kufihlwe.

Namuhla uvele idivayisi, kuvuleke amakhulu amamitha amapayipi ngaphansi phansi ngokuphelele ngaphandle ukuvulwa phansi. Spetstechnology okunjalo zinkulu incurred yikhasimende konga isikhathi nemali.

inketho inzuzo

Trenchless kwakudingeka ezimweni ezimbili: lapho ebeka iphayiphi elisha elalizothatha indawo kwehlulekile noma esikhundleni ezilimele, avimbekile iphayiphi ubudala.

Ukuze abe ipayipi entsha ngokuphelele ku imfucuza ubudala futhi ibenze yona ibanga obudingekayo ishibhile kuka ukuze kumbiwe, ahlukanisa ezilimele futhi ebeka esisha.

Ikakhulukazi indlela entsha ukustaka iba olufanele ezindaweni ezisemadolobheni lapho ukungabi khona iqhinga ngesikhathi imisebenzi ezivelayo izindleko ezihambisana bemba ngamanzi agobhozayo, kunzima ukwenza inkinga kwamaloli nezimoto uma zidlula nje omkhulu.

Trenchless ipayipi kwenza kube nokwenzeka ukufaka ngaphansi imigwaqo, utshani, ezihlukahlukene amapulatifomu, hhayi ebulalayo.

Ukusetha usayizi ipayipi ezincane ngaphakathi ubudala

Lena indlela elula nengabizi yokumiswa Trenchless. Ngokuvamile, umsebenzi onjalo Kwenziwa ngesikhathi kuhlulekile amanzi main. Ngaphakathi ubudala amapayipi ibuthuntu yokwelula a polyethylene entsha. Smooth plastic odongeni permeability vodopotoka hhayi zilulaza.

imikhiqizo polyethylene ziyawathinta lokushisa ukuhlukahluka esikhulu, awekho ngaphansi inqubo ukugqwala. Ziyakwazi ukukhanya, obandayo lula, zamanani aphansi. Ukuphila kwabo ngokuvamile idlula impilo sensimbi amapayipi. Ziyakwazi plastic, goba kalula, okuyinto ebaluleke uma usebenzisa ubuchwepheshe obusha.

Trenchless ipayipi usebenzisa indophi simiswe ngalendlela lelandzelako:

1. Ucezu kuhlulekile yamanzi ipayipi aphule ezindaweni ezimbili ezihlukene.
2. Kwelinye amaphuzu elula kunazo isandla ukukhwezwa indophi.
3. Leli payipi lilungiswe ubude yonke isiswebhu kwaphoqa ikhebula.
4. Ukusebenzisa indophi kanye umugqa isiphika ekhethekile okuqoqiwe ka ungcolisa futhi idiphozi kumiswa.
5. Khona-ke, usebenzisa okufanayo intambo indophi some polyethylene usayizi ukuqhuma.
6. Ukuze plastic ipayipi Flanges inamathelisiwe futhi efakwe valve. Kungenzeka ukuphakela amanzi.

Ukuze emikhulu, lapho amanzi ageleza amandla adonsela phansi (endle, egoba umswakama lutho) amapayipi Ukwethula Kwenziwa kusukela iphuzu elilodwa. Leli payipi libuthene zezinhlamvu iDemo esebenzisa uxhumano threaded noma spikes, futhi njengoba nomhlangano bephushelwa ngaphakathi ipayipi ubudala.

Ukubeka tube ka ububanzi enkulu esikhundleni esidala

Lokhu ukufakwa ipayipi Trenchless ubucwepheshe eziyinkimbinkimbi. Kufanele kube yingxenye Skena wokubacindezela bese ekhiphela uzotshala uwoyela.

Mshini usebenza simiswe ngalendlela lelandzelako:

1. Ngokusebenzisa komsele qeda kanye ubude bayo ikhebula sisalokhu.
2. Ikhebula ukudansela isiginci sakhe phezulu umugqa Skena.
3. Ngemva uwoyela ukumelana hose futha akhishwa umfutho ophakeme Skena ikhulisa ububanzi futhi odlulela kwesigaba imbobo lapho. Broken ipayipi isifaca emhlabathini.
4. Ingcindezi uwoyela kukhishelwa, Skena uthola ivolumu kokuqala kanye indophi edonswa ukuba omunye umugqa ingxenye. Ukuze Skena udonsa Inikezwe isiswebhu entsha.

Izinzuzo Ukwethula entsha uhlelo alondoloze nemithombo yamanzi ngaphakathi noma esikhundleni sobala kuhlulekile. imigwaqo Underground abami plan ayishintshi, asikho isizathu avumelana umsebenzi wokulungisa nezinye izakhiwo ezinkulu konga imali nesikhathi.

Kuphulwa phansi ukushaqeka ishayela pnevmoproboynikom

Le ndlela Trenchless ipayipi kubekwa usebenzisa isando ubuchwepheshe elula. compressor, umoya lipheshulwa liyiswa ngapha nangapha ku hose. Nge-valve control , umoya onomfutho iqala ibenze isando, futhi omunye yesiteleka, hits umzimba ovikelekile.

Umzimba ovikelekile ine obuphelele umxhwele (2 amamitha noma ngaphezulu). Wokubhoboza sici ukuthi pnevmoproboynik kusukela phansi emgodini yokwemba punches isiqondiso rectilinear ovundlile. Awu ohlangene has izindonga bushelelezi.

Kulesi samuntu, emgqeni ukunikeza isiqondiso esifanele kunzima kakhulu. Nakuba, uma ngokucophelela nizifeze zonke lezi izibalo ezidingekayo, - kungenzeka. Kukhona futhi wathumela ukushaqeka-ishayela punches. Kodwa ngenxa yezinkinga ezithile lobuchwepheshe banayo umkhiqizo ongaphakeme.

Ukubeka ipayipi jacking indlela

Lokhu okufana Trenchless ipayipi kubekwa babevame egodini. Steel ipayipi ukuphela kwayo bephushelwa walihlanganisa nomhlabathi phansi. Cavity ke avimbekile phansi. Ngemva kwalokho, inhlabathi isuswa emoyeni onomfutho noma izipikili ezikhethekile, okuyinto, njengoba siphika, ahlanze ingaphakathi iphayiphi.

Isetshenziselwa ngokucindezela Jacks wokubacindezela amandla aphezulu. iyunithi okunjalo kufanele kube ukwesekwa eqinile, okuyinto ngezinye izikhathi kwakuba nzima ukuthola. Ngakho-ke, ngo-pair of Jacks isebenze kudivayisi vibroimpact odlulela projectile e spurts encane.

Onjalo gasket indlela ephawulekayo ngalolo kungenzeka ukusebenzisa isando ohlangothini oyifunayo esikhulu ubukhulu tube (2500 mm).

Kokuqondisa imishini ovundlile

Kuyinto inketho ezibizayo kunazo zonke ngenhla. Kodwa-ke has a inzuzo enkulu. Trenchless okunjalo kubekwa amapayipi isetshenziswa uma ezinye izindlela kakade ayizwakali. Uma usebenzisa le ndlela, ungakwenza isitayela nemivimbo engu akho ngisho rock.

Ngomqondo onabile, inkulumo indlela uqobo sifana inqubo evamile imishini, kodwa kuphela isiqondiso ovundlile. Izinga ukudlula zokwakheka uyahluka amamitha ngehora 1.5 kuya ku-20. Kodwa kule samuntu, sebenzisa ezivamile sokuprakthiza ipayipi bengayi. Torque kusukela injini idluliselwa ku umlomo wombhobho esebenzisa ekhethekile sokuprakthiza izinduku, abethela ngu kokuhlanganisayo.

Drilling edwaleni enqubeni kuhilela ukusetshenziswa imishini nasodakeni. Kuyinto uhlobo igrisi futhi ingxenye lwaluyophola kuya kancane sokuprakthiza. Isixazululo iphinde ilungise odongeni Borehole, singavumeli ukusabalalisa, lapho esiza ukuqeda imithelela imishini.

Ukuze umphumela kahle ehilela tube entsha. Kodwa inqubo imishini kuyoba engenamsebenzi uma indlela womthombo uzohlangana kulandela komhlaba.

ibanga

Amashubhu of ububanzi ezincane ngokusebenzisa bakhathale indophi umugqa besondele at ibanga amamitha 500. Ezinye izindlela Trenchless ukuvumela ukuba abeke isiswebhu at ibanga 40-80 amamitha. Umsebenzi ukuthuthukiswa lobu buchwepheshe waqala kwenziwe akunjalo kudala, ngakho ezingaba usizo izinhlelo athuthukile omkhulu.

Trenchless neze asule lusetshenziswa nsuku zonke. Uma kukhona isidingo ukuxhuma amanzi yokuhlala yangasese, kungcono baphendukela usizo Excavator. Noma, ezimweni ezibucayi, lokwela ezivamile. Lona ngumphumela ekupheleni uyaphuma engabizi.
