中文MJS njira mulu(Metro Jet System), yomwe imadziwikanso kuti all-round-high-pressure jetting, idapangidwa poyambirira kuti ithetse mavuto a slurry discharge komanso kukhudzidwa kwa chilengedwe pomanga ndege zopingasa. Pakali pano amagwiritsidwa ntchito kwambiri pochiza maziko, kuchiza kutayikira ndi zovuta zamtundu wa dzenje losungira madzi chotchinga choyimitsa madzi, ndikuchiza madzi otuluka pakhoma lakunja la chipinda chapansi. Chifukwa cha ntchito yapadera porous mipope ndi kutsogolo-mapeto anakakamizika slurry kuyamwa zipangizo, anakakamizika slurry kumaliseche mu dzenje ndi pansi kuthamanga kuwunika anazindikira, ndi kuthamanga pansi ndi kulamulidwa ndi kusintha anakakamizika slurry kumaliseche voliyumu, kuti zozama matope kumaliseche ndi Kuthamanga kwapansi kumayendetsedwa momveka bwino, ndipo kupanikizika kwapansi kumakhazikika, zomwe zimachepetsa kuthekera kwa kusinthika kwapamwamba panthawi yomanga ndikuchepetsa kwambiri kukhudzidwa kwa chilengedwe. Kuchepetsa kuthamanga kwa nthaka kumatsimikiziranso kukula kwa muluwo.
Pre-control
Kuyambira kuMtengo wa MJSukadaulo wa zomangamanga ndizovuta komanso zovuta kwambiri kuposa njira zina zopangira ma grouting, ndikofunikira kutsatira mosamalitsa zofunikira pakupanga panthawi yomanga, kuchita ntchito yabwino yolumikizana ndiukadaulo ndi chitetezo, ndikutsata njira zogwirira ntchito kuti muwonetsetse kuti ntchito yomangayo ndi yabwino. .
Pambuyo pobowola m'malo, malo a mulu ayenera kuyendetsedwa bwino. Nthawi zambiri, kupatuka kwa kapangidwe kake sikuyenera kupitilira 50mm, ndipo kupatuka koyima sikuyenera kupitilira 1/200.
Asanayambe kumanga, kuthamanga ndi kutuluka kwa madzi othamanga kwambiri, pampu yothamanga kwambiri ndi mpweya wa compressor, komanso kuthamanga kwapamwamba, kuchuluka kwa grouting, ndi dzenje lomaliza la chitoliro cha grouting panthawi ya jekeseni zimatsimikiziridwa kupyolera mu mayesero. milu. Pakumanga kokhazikika, centralized management console imatha kugwiritsidwa ntchito potsata ndi kuwongolera. Lembani mwatsatanetsatane zolemba zosiyanasiyana zomanga pamalopo, kuphatikiza: kukumba mobowola, kuya kwa kubowola, zopinga kubowola, kugwa, magawo ogwirira ntchito panthawi ya jakisoni wa slurry, slurry return, ndi zina zambiri, ndikusiya makiyi azithunzi. Pa nthawi imodzimodziyo, zolemba zomanga ziyenera kusanjidwa panthaŵi yake, ndipo mavuto ayenera kufotokozedwa ndi kusamaliridwa panthaŵi yake.
Pofuna kuonetsetsa kuti palibe kusweka mulu pamene kubowola ndodo disassembled kapena ntchito inasokonekera kwa nthawi yaitali chifukwa cha zifukwa zina, palinso kutalika kwa milu chapamwamba ndi m'munsi zambiri zosakwana 100mm pamene jekeseni wabwinobwino ayambiranso. .
Sungani makina omanga asanamangidwe kuti muchepetse zovuta zomwe zimachitika chifukwa cha kuwonongeka kwa zida pakumanga. Chitani maphunziro omanga chisanadze kwa ogwiritsa ntchito makina kuti adziwe momwe zida zimagwirira ntchito komanso momwe zida zimagwirira ntchito. Panthawi yomanga, munthu wodzipereka ndi amene ali ndi udindo woyang'anira zipangizo.
Kuyendera musanamangidwe
Pamaso kumanga, zopangira, makina ndi zida, ndi kupopera mbewu mankhwalawa ndondomeko ayenera kuyendera makamaka mbali zotsatirazi:
1 Satifiketi yapamwamba ndi malipoti oyesa amboni azinthu zosiyanasiyana zopangira (kuphatikiza simenti, ndi zina), kusakaniza madzi kuyenera kukwaniritsa malamulo ofananira;
2 Kaya chiŵerengero cha slurry mix ndi choyenera pa nthaka yeniyeni ya polojekitiyo;
3 Kaya makina ndi zida ndizabwinobwino. Asanamangidwe, zida zamtundu wa MJS zozungulira kwambiri zozungulira, zobowola dzenje, pampu yamatope yothamanga kwambiri, maziko osakanikirana a slurry, mpope wamadzi, ndi zina zotere ziyenera kuyesedwa ndikuthamanga, ndi ndodo yobowola (makamaka ndodo zingapo zobowola) , kubowola pang'ono ndi chipangizo chowongolera chiyenera kukhala chosasokoneza;
4 Onani ngati kupopera mbewu mankhwalawa kuli koyenera malinga ndi momwe zinthu zilili. Pamaso yomanga, ndondomeko mayeso kupopera mbewu mankhwalawa ayeneranso kuchitidwa. Kuyezetsa kupopera mbewu mankhwalawa kuyenera kuchitika pamalo oyamba mulu. Chiwerengero cha mayeso kupopera mbewu mankhwalawa mulu mabowo sayenera zosakwana 2 mabowo. Ngati ndi kotheka, kusintha ndondomeko kupopera mbewu mankhwalawa magawo.
5 Musanamangidwe, zopinga zapansi pa nthaka ziyenera kufufuzidwa mofanana kuti zitsimikizire kuti kubowola ndi kupopera mankhwala kumakwaniritsa zofunikira za mapangidwe.
6 Yang'anani kulondola ndi kukhudzika kwa malo a mulu, kupima kuthamanga ndi mita yothamanga musanamangidwe.
Kuwongolera mkati
Panthawi yomanga, zotsatirazi ziyenera kutsatiridwa:
1 Yang'anani kutalika kwa ndodo yobowola, kuthamanga kwa kubowola, kuya kwa kubowola, kuthamanga kwa kubowola ndi liwiro lozungulira nthawi iliyonse kuti muwone ngati zikugwirizana ndi zofunikira za lipoti la mayeso a mulu;
2 Yang'anani chiŵerengero cha simenti slurry mix ndi muyeso wa zipangizo zosiyanasiyana ndi zosakaniza, ndipo lembani moona mtima kuthamanga kwa jekeseni, kuthamanga kwa jekeseni ndi voliyumu ya jekeseni panthawi yopangira jekeseni;
3 Kaya zolemba zomangira zatha. Zolemba za zomangamanga ziyenera kulemba kuchuluka kwa mphamvu ndi kayendedwe kake kamodzi pa 1m iliyonse pokweza kapena pamphambano wa nthaka wosanjikiza wa nthaka, ndi kusiya zithunzi ngati kuli kofunikira.
Kuwongolera pambuyo
Ntchito yomangayo ikatha, nthaka yolimbikitsidwa iyenera kuyang'aniridwa, kuphatikizapo: kukhulupirika ndi kufanana kwa nthaka yophatikizidwa; m'mimba mwake ogwira wa consolidated nthaka; mphamvu, pafupifupi m'mimba mwake, ndi mulu pakati pa malo a nthaka consolidated; kusalolera kwa dothi lophatikizidwa, etc.
1 Nthawi yowunika bwino komanso zomwe zili
Popeza kulimba kwa dothi la simenti kumafuna nthawi yochulukirapo, nthawi zambiri kuposa masiku 28, zofunikira zenizeni ziyenera kutengera zolemba zamapangidwe. Choncho, kuyendera khalidwe laKupopera mbewu kwa MJSntchito yomanga iyenera kuchitika pambuyo poti MJS high-pressure jet grouting yatha ndipo zaka zikufika pa nthawi yodziwika popanga.
2 Quality kuyendera kuchuluka ndi malo
Chiwerengero cha malo oyendera ndi 1% mpaka 2% ya kuchuluka kwa mabowo opopera mbewu. Kwa mapulojekiti omwe ali ndi mabowo osakwana 20, mfundo imodzi iyenera kuyang'aniridwa, ndipo yomwe yalephera iyenera kupoperanso. Malo oyendera ayenera kukonzedwa m'malo otsatirawa: malo okhala ndi katundu wamkulu, mizere yapakati pa milu, ndi malo omwe mikhalidwe yachilendo imachitika panthawi yomanga.
3 Njira zoyendera
Kuyang'anira milu ya jet grouting makamaka kuyang'ana katundu wamakina. Nthawi zambiri, kuchuluka kwamphamvu kwa nthaka ya simenti kumayesedwa. Chitsanzocho chimapezedwa pobowola ndi kukokera, ndipo chimapangidwa kukhala gawo loyesera. Pambuyo pokwaniritsa zofunikira, kuyezetsa katundu wamkati ndi makina kumachitika kuti muwone kufanana kwa dothi la simenti ndi makina ake.
