Trenchless kuika mipope: Njira kufotokoza

Sayansi ya trenchless chitoliro atagona pamenepo kwa nthawi yaitali. Back mu 80s wa pipelayers atumwi wotsiriza kuyika mu chitoliro pansi ngalande. M'malo kukumba ngalande limagwirira yopapatiza anatumbula, ndi kumene zobisika chingwe kapena madzi.

Today anaonekera chipangizo, amaika mumsewu mazanamazana mamita mapaipi pansi kwathunthu popanda nthaka ija. Chotero Spetstechnology kuposa ndalama anapalamula makasitomala amapulumutsa nthawi ndi ndalama.

opindulitsa njira

Trenchless zofunika milandu iwiri: pamene atagona pa payipi yatsopano m'malo analephera kapena m'malo owonongeka yatsekera ndi payipi akale.

Ndi chitoliro zatsopano mu zinyalala akale ndipo kanikizirani kutali chofunika ndi mtengo kwambiri kuposa una, dismantle zowonongeka ndi kuika wina watsopano.

Makamaka njira yatsopano ya stacking amakhala okhudzidwa m'tawuni kumene pakalibe kuzemba pa ntchito mosayembekezera ndalama kugwirizana ndi zofukulidwa la madzi, ndi zovuta kwambiri kuti vuto magalimoto otaya chabe chachikulu.

Trenchless chitoliro limachititsa kukhazikitsa pansi misewu, kapinga, zosiyanasiyana nsanja, osati kuwawononga.

Kupereka ang'onoang'ono chitoliro kukula mu zaka

Izi ndi njira yosavuta komanso yotsika mtengo wa trenchless unsembe. Childs, ntchito imeneyi ikuchitika pa analephera madzi chachikulu. Mkati mwa mipope akale dzimbiri kutambasula ndi polyethylene latsopano. Yosalala pulasitiki khoma permeability vodopotoka osati kunyoza.

Polyethylene mankhwala zimakumana yofanana lalikulu kutentha, simuli pansi pa ndondomeko dzimbiri. Iwo ali kuwala, zosavuta kukhazikitsidwa, otsika mtengo. moyo wawo zambiri kuposa moyo wa mapaipi pulasitala zitsulo. Iwo pulasitiki, unakhota mosavuta, umene uli wofunika pamene ntchito luso latsopano.

Trenchless chitoliro ntchito winch chiri motere:

1. A chidutswa analephera wa chitoliro madzi ziboola malo awiri.
2. Mu umodzi ndi mfundo yabwino kwambiri sankalimbana nafe wokwera winch.
3. Chitoliro ukonzedwe utali wonse wa chikwapu anakankhira chingwe.
4. Ntchito winch ndi wapadera mzere ruff nakonza wa fouling ndi gawo mapangidwe.
5. Kenako, pogwiritsa ntchito yemweyo chingwe winch omangika polyethylene kuuza kukula.
6. Pakuti flanges pulasitiki chitoliro amagwira ndipo anaika valavu. N'zotheka kupereka madzi.

Chifukwa misewu, pamene madzi umayenda ndi mphamvu yokoka (bere, anaŵerama chinyezi chilichonse) mipope broaching ikuchitika mfundo imodzi. Chitoliro ndi anasonkhana ndalama yochepa mwa kulumikiza yamazinga kapena spikes, ndipo khamu akankhidwira mkati chitoliro akale.

Kuika chubu cha m'mimba mwake wamkulu m'malo akale

Izi trenchless chitoliro unsembe ndi luso zovuta zambiri. Ziyenera kukhala mbali ya calibrator hayidiroliki ndi kutulutsa ikukoka mafuta.

Limagwirira ntchito ndi izi:

1. Kudzera utsi ngalande mulitali anatambasula chingwe.
2. Chingwe imakoka pamwamba pa mzere calibrator.
3. Pambuyo mpope mafuta kugonjetsedwa payipi amawapopa kuthamanga calibrator zambiri awiri ndi amakankhira chigawo ritsa kumene. Wosweka chitoliro ni mu nthaka.
4. Kuthamanga mafuta akatulutsidwa, calibrator amalandira buku poyamba winch ali anakoka kwa ena mzere gawo. Pakuti calibrator kumawakoka anatuma chikwapu latsopano.

Ubwino broaching latsopano dongosolo madzi mkati kapena malo zoonekeratu analephera. Misewu mobisa kumalumikiza dongosolo sasintha, palibe chifukwa kugwirizanitsa anakonza mpandawo ndi nyumba zina kuti amapulumutsa kwambiri ndalama ndi nthawi.

Kunyema pansi mantha zimachitika pnevmoproboynikom

Njira imeneyi trenchless chitoliro kuika ntchito nyundo luso yosavuta. kompresa, mpweya Nkhuntho mu payipi ya. Ndi valavu kulamulira , wothinikizidwa mpweya wayamba kulikankhira nyundo, ndi wina chogunda, udzaphwanya thupi streamlined.

Thupi streamlined ali yaitali chidwi (2 mamita kapena kuposa). Puncture mbali ndi pnevmoproboynik kuchokera pansi pa una yomanga nkhonya rectilinear yopingasa malangizo. Chabwino ting'onoting'ono basi makoma yosalala.

Mu chimake ichi, mzere kupereka yoyenera n'kovuta kwambiri. Ngakhale ngati mosamala kugwira kuwerengetsera zonse zofunika, - zotheka. Pali ndipo anatumiza mantha-zimachitika nkhonya. Koma chifukwa cha mavuto ena luso ali zokolola otsika.

Kuika chitoliro jacking njira

zosinthika uyu wa trenchless chitoliro kuika nthawi zambiri ungaonongeke. Zitsulo chitoliro kutha akankhidwira mu nthaka. M'mimbamo izo yatsekera pansi. Zitatero, nthaka chikutha ndi wothinikizidwa mpweya kapena wononga wapadera, amene, monga ruff, aisadza mkati mwa payipi ya.

Ntchito kulimbikira jacks hayidiroliki mphamvu yapamwamba. Chotero amodzi ayenera kukhala thandizo lamphamvu, chimene ndi zina kovuta. Choncho, awiri jacks ntchito chipangizo vibroimpact amakankhira kwa projectile mu chikulavula yaing'ono.

Chotero njira gasket ndi kwambiri kuti n'zotheka ntchito nyundo malangizo Napempha kwa lalikulu awiri chubu (2500 mm).

Polozera yopingasa pobowola

Ndi kwambiri mtengo asankhe onse pamwamba. Koma ali ndi mwayi waukulu. Chotero trenchless kuika mapaipi ntchito pamene njira zina kale operewera. Pamene ntchito njirayi, mukhoza kukongoletsa akulankhula mokalipa wako thanthwe.

Mfundo njira yokha akufanana ndi wabwinobwino pobowola ndondomeko, koma malangizo yopingasa. Mlingo wa chigawo cha formations zimasiyanasiyana pakati pa mamita 1.5 20 pa ola limodzi. Koma chimake, gwiritsani ntchito ochiritsira kubowola chitoliro sindingakhoze. Makokedwe kwa injini imafalikira ndi nozzle kudzera ndodo wapadera kubowola, ananamizira ndi kumadalira.

Pobowola m'thanthwe la ndondomeko zimaphatikizapo kugwiritsa ntchito pobowola matope. Ndi mtundu wa lubricant ndi chigawo yozizira ku pang'ono kubowola. Yankho komanso atakhazikitsa khoma osati zitsime zokumba zogwiritsa, osalola kulalikira, pamene kuthandiza kuthetsa zotsatira za kuboola.

Kuti chifukwa tingafunike chubu latsopano. Koma ndondomeko pobowola idzakhala yopanda phindu ngati njira ya bwino amakumana izi pansi pa.

mtunda

Machubu a awiri ang'onoang'ono kupyolera ankavala winch mzere kukopedwa pa mtunda wa mamita 500. njira zina trenchless kulola kuyika chikwapu pa mtunda wa mamita 40-80. Ntchito pa chitukuko cha njira imeneyi unayamba ikuchitika osati kalekale, choncho angathe gwero mapulogalamu anayamba ndi waukulu.

Trenchless konse kulipira ntchito tsiku ndi tsiku. Ngati pali kufunika kugwirizana kwa madzi malawi payekha, ndi bwino amachita misonkhano ya excavator ndi. Kapena, mu zikafika poipa, ochiritsira fosholo. Izi ndi zotsatira akutuluka yotsika mtengo.
