中文Pa Januware 15, maphunziro aukadaulo a 2024 osagwiritsa ntchito mapaipi komanso maphunziro ozindikira mapaipi omwe adathandizidwa ndi Pipeline Trenchless Crossing Technology Professional Committee ya China Petroleum Engineering and Construction Association adamalizidwa bwino ku Shanghai Construction Management Vocational and Technical College. Anthu ochokera ku madzi, ngalande, madzi a mvula Opitilira 50 oyang'anira ntchito, okonza mapulani, oyang'anira, akatswiri a uinjiniya, ndi akatswiri ofufuza asayansi omwe adagwira nawo ntchito yomanga ndi kukonzanso mapaipi apansi panthaka (ma network) ndi makonde a mapaipi monga magetsi, kutentha, nthawi yayitali- mtunda wa mafuta ndi gasi, komanso kuteteza madzi kudatenga nawo gawo pamaphunzirowa ndikuzidziwa bwino kudzera muukadaulo wophunzirira matekinoloje okhudzana ndi kuthamangitsa chitoliro chosasunthika komanso luso lozindikira mapaipi kuti apititse patsogolo luso laukadaulo komanso kuthekera kothandiza kwa mayunitsi okhudzana ndi trenchless ndikuchepetsa zoopsa zomanga.
M’zaka zaposachedwapa, ntchito yomanga mapaipi apansi panthaka yakwera kwambiri. Kuti agwiritse ntchito mokwanira zinthu zakuthambo zapansi panthaka ndikuwonetsetsa kuti mzindawu ukuyenda bwino, mapaipi ochulukira amayalidwa pogwiritsa ntchito njira monga kuthamangitsa mapaipi opanda ngalande. Pamene zofunikira za zomangamanga zikupitilirabe, kukumba pamanja ndiukadaulo wakumbuyo komanso kusagwira bwino ntchito bwino kumathetsedwa pang'onopang'ono. Tekinoloje ya Trenchless ndiyoyamba kukwezedwa m'mizinda yayikulu komanso yapakatikati, zomwe zidzatsegulenso msika wawukulu mtsogolo.
Monga wogwirizanitsa nawo, Shanggong Machinery adakhudzidwa kwambiri ndi maphunzirowa. Popeza Shanggong Machinery's PJR mndandanda yaying'ono chitoliro jacking rigs ndi PIT mndandanda press-mu shaft chitoliro kugudubuza makina anabweretsedwa kumsika, iwo apeza mbiri yaikulu ponena za operability, kudalirika, chitetezo ndi bwino. Ubwino wake wampikisano wokwanira pakugonana ndi mbali zina mwachangu zidawonekera pamsika ndikukondedwa ndi ogwiritsa ntchito kulikonse.
Msonkhano Wapakati wa Ntchito Zachuma wa 2021 unatsindika kuti mu nthawi ya "14th Year-Fin Plan", kukonzanso ndi kumanga mapaipi kuyenera kuonedwa ngati ntchito yofunika kwambiri ya zomangamanga, ndipo kufunikira kofulumizitsa kukonzanso ndi kukonzanso mapaipi okalamba m'matauni. Dipatimentiyi inapereka lamulo loti misewu ya m’tauni siloledwa kukumba mwakufuna kwake. Njira yokwirira mapaipi "yotseguka ndi yotsekeka" ndi yachikale. Tekinoloje ya "Minimally invasive" ndiyomwe imayendera ndikuyika mapaipi. Ukadaulo wa Trenchless ndiye ukadaulo wa "minimally invasive" wamapaipi. Chitukuko chamtsogolo Chiyembekezo chokulirapo.
Munthu amene amaona mmene zinthu zilili ali wanzeru, ndipo amene amaona mmene zinthu zilili ndi wanzeru. SEMW ipitiliza kupanga zinthu m'njira zotsika pansi, kuthana ndi zotchinga zaukadaulo, kupereka ntchito zodzipereka, kupita patsogolo ndikupikisana pamsika kachiwiri, kulimbikira kupita mozama kutsogolo kwa msika, kukwaniritsa zosowa zamakasitomala, pitilizani. kuchita luso laukadaulo, ndikutenga mwayi pakukula kwamakampani kuti agwire ntchito ndi aliyense. Fufuzani chitukuko!
PJR mndandanda wa microkubowola chitolirochida:
Micro chitoliro jacking chimagwiritsidwa ntchito madzi ndi mipope zimbudzi, nthambi mapaipi a mapaipi mpweya, mphamvu yamagetsi, mauthenga ndi mapaipi ena. Njira yomangira chitoliro cha chitoliro ndiyoyamba kukhazikitsa chobowolera chitoliro mu ntchito bwino, choyamba kubowola chitoliro chobowola m'nthaka pakatikati pa chitoliro kuti mudziwe kalozera wa chitoliro, ndiyeno gwiritsani ntchito kubowola kwa helical reaming kuti mukulitse. dzenje kwa anakonza chitoliro awiri. Chitoliro choyikidwa ndi chothina. Kutsatira kachulukidwe ka auger, chitolirocho chimakumba pansi pa dothi pansi pa cylinder yayikulu yamafuta. Nthaka yofukulidwayo imatayidwa ndi mpope wa dothi kapena screw conveyor kapena imatulutsidwa ngati matope kudzera pampope yamatope. Pambuyo popititsa patsogolo gawo la chitoliro, jack yaikulu imachotsedwa, gawo lina la chitoliro limakwezedwa, ndipo kugwedeza kumapitirirabe. Bwerezani izi mpaka payipi itayikidwa. Kuyika kwa chitoliro kumalizidwa, chitoliro cha chida chimakwezedwa kuchokera pamtengo wolandila kupita pamwamba.
Mawonekedwe:
■ Ntchito yomangayi imakhudza kadera kakang’ono, sikuwononga misewu yomwe ilipo, ndipo sikukhudza kwambiri magalimoto;
■ Phokoso lochepa la zomangamanga, kuchepa kwa matope, kuwononga chilengedwe, ndi chitetezo chapamwamba cha zomangamanga;
■ Kukonzekera kwapamwamba kwambiri, luso lamakono lamakono, kufulumira kwa zomangamanga ndi kutsika mtengo wa zomangamanga.

PIT mndandanda akanikizire mu shaft chitoliro kusisita makina:
Njira yomangira ya PIT imagwiritsa ntchito makina ogubuduza chitoliro chogwedeza-mu shaft kukanikizira chosungira chakunja chapadera (silinda yachitsulo) pansi ndikuchigwedeza. Dzenje la maziko limamangidwa pofukula mbali ya chitsulo chosungirako. Poyerekeza ndi ntchito zina zitsulo pepala mulu thandizo, njira yomanga kugwedera, phokoso otsika, kupulumutsa mphamvu ndi kuteteza chilengedwe zimasonyeza kwambiri luso chitetezo, chuma ndi dzuwa.
Makina a PIT osindikizira mu shaft chitoliro ndi chida chatsopano chobowolera pawokha chopangidwa ndi Shanggong Machinery pamaziko oyambitsa, kugaya ndi kuyamwa ukadaulo wapamwamba wakunja. Zimaphatikiza ma electromechanical ndi hydraulic control. Makinawa ali ndi ntchito zambiri, amatha kusintha komanso opepuka, ndipo amakhudza ntchito zamitundu yosiyanasiyana kunyumba ndi kunja. Zili ndi zizindikiro za maulendo angapo othamanga ndi ma torque, kusintha kwachindunji, kuwongolera mphamvu ya mutu wa cutter, kulamulira kwa waya kutali, ndi zina zotero. Wapamwamba ndi wodalirika.
Kuchuluka kwa ntchito:
■ Maziko apansi panthaka, dzenje lakuya la maziko otsekereza milu yotchinga, milu yomanganso m’tauni ndi milu yochotsa zopinga, milu yoboola ya njanji, madoko, misewu ndi milatho, mitsinje, nyanja, nyumba zazitali, zopangira magetsi opangira madzi ndi madzi osungira madzi, ndi kutopa ndi cholinga chapadera. milu;
■ Imatengera casing yonse ndipo imatha kumangidwa pafupi ndi nyumba zomwe zilipo kale. Ndikoyenera kwambiri kugwira ntchito m'matauni.
Mawonekedwe:
Kumanga kotetezeka komanso koyenera
■ Ogwira ntchito safunikira kugwira ntchito mu dzenje la maziko, ntchito zonse zimachitika pansi, kuonetsetsa chitetezo cha ogwira ntchito moyenera; panthawi yomanga, chitsulo chosungiramo chitsulo chimatha kusunga nthaka ndikuteteza khoma, kuthetsa bwino zoopsa zobisika za kugwa kwa nthaka ndi kuzama kwa maziko;
Zipangizozi ndi zosinthika komanso zopepuka komanso zopepuka ndipo zitha kugwiritsidwa ntchito pomanga wamba ngakhale m'malo opapatiza amisewu. Ngakhale pamaziko omwe alibe kudzidalira, palibe chifukwa cha njira zothandizira monga jekeseni wakuthupi ndipo ndizoyenera kumanga pamitundu yosiyanasiyana ya maziko.
Palibe kugwedezeka, phokoso lochepa
Chophimba chachitsulo chimakanikizidwa ndikutulutsidwa kudzera mu hydraulic cylinder operation, yomwe sichitha kugwedezeka komanso phokoso lochepa.
Kuchita bwino kwambiri kumatsimikizira kulondola kwa zomangamanga
■ Dongosolo lanzeru limathandiza ogwira ntchito yomanga kuti amvetsetse momwe zida zimagwirira ntchito;
■ Zidazi zimatha kuonetsetsa kuti zitsulo zachitsulo zimakhala zowongoka mwadongosolo lapamwamba lowongolera, kupereka mphamvu yokhazikika yokhazikika pamagulu osiyanasiyana, ndikuonetsetsa kuti zomangamanga zapamwamba kwambiri.
