Njira yatsopano yotetezera zachilengedwe ya SEMW ndi zida zimalumikizana manja kuti ziwukirenso
Ma seti 3 a makina obowola osasunthika ndi makina odulira mizu amaima molunjika ndi mzere
pansi "ozika mizu"
Ntchito Yopanga (Wuxi) ya Hua Hong
Maziko a Ramming, mizati ndi mizati
Monga mzinda wapakati pazachuma wa 15 ku China, Wuxi ili ndi makampani opanga zinthu zolimba ndipo ndiye maziko opangira zinthu m'chigawo cha Yangtze River Delta.Posachedwa, gawo lachiwiri la malo opangira Huahong Manufacturing (Wuxi) likumangidwa.Mphamvu yayikulu, SEMW, ili ndi ma seti atatu a SDP mndandanda wazobowola ndi zida zamakina odulira mizu, kugwirira ntchito limodzi, kutsutsa nthawi zonse malire omanga, ndikuperekeza pulojekitiyo moyenera komanso mokhazikika.
Pulojekiti ya Huahong Manufacturing (Wuxi) ili ndi malo okwana masikweya mita 114,000, ndi malo omanga okwana 530,000 masikweya mita.Pali mayunitsi 33 okwana, kuphatikizapo: chachikulu chopangira magetsi, malo opangira magetsi, nyumba zosungiramo 10, makonde 4, makonde 2 mapaipi, milatho 7 yamapaipi, ndime zapansi panthaka ndi nyumba zina.Ntchito ikamalizidwa, idzamanga gulu la mafakitale ophatikizika padziko lonse lapansi ku Wuxi ndikupereka mphamvu zamphamvu "zoyambira".
Maziko a mulu wa ntchito yopangira maziko amatengera njira yobowola ndi mizu, ndipo kuchuluka kwa milu ya mizu ndi 160,000 metres.Maseti atatu a SDP mndandanda wosasunthika pobowola ndi mizu yobowola zida za Shanggong Machinery kupanga milu 20 (kuzama kwa mulu 21m) ndi milu 17 (Kuzama kwa mulu ndi 52m) ndi ntchito yomanga milu yolimba kwambiri yadziwika bwino ndi makasitomala.Zipangizozi zitha kufananizidwa ndi JB160M, JB170M, ndi JB180M njanji ziwiri zowongolera njanji zomangira.
Monga wobiriwira ndi wochezeka m'badwo watsopano mulu maziko zida zomangira zoyenera pobowola malo amodzi ndi kumanga mizu kwathunthu paokha opangidwa ndi SEMW, zigawo zikuluzikulu za SEMW SDP mndandanda pobowola ndi rooting makina kutengera zopangidwa mayiko otchuka, ndi makokedwe lalikulu ndi pobowola kuya kwakukulu. , zamakono zamakono, zodalirika zabwino, zomangamanga zapamwamba ndi makhalidwe ena, ntchitoyo yafika pamtunda wapadziko lonse.
Kuyambitsa Static Drilling ndi Rooting Njira
Njira yobowola ndi mizu ndikugwiritsa ntchito njira yobowola ndi mizu ndikubowola mabowo, kusakaniza njira yonse ndikukulitsa pansi, kenako ndikuyika mulu wopangidwa kale, ndiye kuti, milu yansungwi yokhazikika (PHDC), yoyerekezeredwa. Milu ya nsungwi ya prestressed Mafotokozedwe osiyanasiyana ndi mitundu ya milu ya mipope ya konkriti (PHC) ndi milu yapaipi ya konkriti yokhazikika (PRHC) amaphatikizidwa m'njira zosiyanasiyana kuti akwaniritse zofunikira za kapangidwe kake, ndipo ntchito yomanga imachitika molingana ndi kubowola, kubwezeretsa, grouting, implantation ndi njira zina mulu maziko njira.
Zofunika za njira yomanga:
● Palibe kutulutsa nthaka, kugwedezeka, phokoso lochepa;
● Ubwino wa muluwo ndi wabwino, ndipo kukwera kwa mulu wa mulu kumakhoza kulamuliridwa;
● Kuponderezedwa kolimba kwambiri, kutulutsa ndi kukana katundu wopingasa;
●Kuchepa kwamatope;
● Ili ndi phindu labwino pagulu komanso kukwezedwa.
Kuchuluka kwa ntchito:
● Yogwiritsidwa ntchito kumadera omwe ali ndi mphamvu zosiyanasiyana za seismic, zomwe zimagwiritsidwa ntchito mulu: 500-1200mm;
Dothi lophatikizana, silt, dothi lamchenga, nthaka yodzaza, yophwanyidwa (mwala) nthaka yamwala, ndi mapangidwe amiyala okhala ndi zovuta zachilengedwe, ma interlayers ambiri, nyengo yosagwirizana, ndi kusintha kwakukulu kwa kuuma ndi kufewa, kuya kwakukulu kwa kulowa: 90m;
Pakakhala nyumba (zomangamanga) kapena mapaipi apansi panthaka ndi zida zina zaumisiri pafupi ndi malo omanga, kugwiritsa ntchito mitundu ina ya milu kungayambitse mavuto;
Pamene kukwera pamwamba pa kunyamula wosanjikiza kumapeto kwa mulu kumasintha kwambiri, kutalika kwa mulu kumakhala kovuta kudziwa molondola, malo omanga sakupezeka, mikhalidwe yothira konkire pa malo kapena khalidwe la konkire kuthira pa malo. sikophweka kutsimikizira;
●Ma projekiti okhala ndi zoletsa pakutulutsa matope ambiri;
● Kukonzekera kumafuna kuti mphamvu yobereka ya mulu umodzi ikhale yaikulu, ndipo zizindikiro zaumisiri ndi zachuma ndi zomangamanga ndizopambana kuposa mitundu ina ya mulu.
Kuyambitsa makina a SDP Static Drilling and Rooting Machine
Mndandanda wa SDP static pobowola ndi rooting pobowola rig ndi m'badwo watsopano wa zinthu zobowola pawokha zopangidwa ndi Shanggong Machinery, zomwe ndi zoyenera pomanga pobowola komanso njira yodulira mizu, pogwiritsa ntchito mwayi wopeza luso lophatikizira zida zophatikizira zozama. kwa zaka zambiri.
Zofunika za njira yomanga:
1, Landirani luso lokulitsa lapamwamba la mafuta, pansi pakukulitsa m'mimba mwake ndi nthawi 1-1.6 za m'mimba mwake, kutalika kwapansi ndi nthawi 3 pobowola m'mimba mwake, ndipo njira yojambulira yapakompyuta yotsika kwambiri imagwiritsidwa ntchito kuyang'anira. ntchito yomanga Deta zosiyanasiyana m'dongosololi zimalembedwa ndikuwunikidwa kuti apange ma curve ofanana a data.
2, Atengereni wanzeru zomangamanga kasamalidwe mapulogalamu, ulamuliro utenga mode wanzeru kukhudza zenera, kuwunika ndondomeko yomanga mu nthawi yeniyeni kuonetsetsa ntchito zomangamanga, deta zonse zomangamanga zikuonekera bwino chionetserocho ndi basi kusungidwa, ndipo akhoza linanena bungwe ndi kusindikizidwa.
3. Njira yogwiritsira ntchito imakhala ndi pulogalamu yamagetsi yamagetsi ya 380V, yomwe imatsimikizira kuti deta sichidzatayika chifukwa cha kuwonongeka kapena kulephera kwa mphamvu panthawi yogwiritsira ntchito pobowola.
4. Njira yoyambira yamagalimoto imatenga chiyambi chofewa, ndipo choyambira chofewa chokha chimakhala ndi ntchito zosiyanasiyana zoteteza magalimoto, monga kutsika kwamphamvu, kutayika kwa gawo, kutsatizana kwa gawo, kuchulukirachulukira ndi zoteteza zina.
5. Kugwira ntchito kwa teknoloji yowonjezera pansi pa hydraulic ndi yodalirika, ndipo zigawo zamtundu wa hydraulic zimagwiritsidwa ntchito kuti zitsimikizidwe kuti ntchito yabwino ya kuwonjezereka kwapansi kwa hydraulic pansi pa kuya kwa 80m.
Ubwino wa static kubowola ndi mizu milu
Kubowola kosasunthika ndi mulu wa mizu kumatengera makina obowola opanda phokoso (kubowola static) ndi njira yophatikizika yomaliza ukadaulo wa maziko a mulu wopangidwa kale (mulu wobzala), womwe ndi katswiri waukadaulo wamakono wa milu.Pambuyo pazaka zambiri za kutchuka ndi kugwiritsa ntchito, ubwino wake waukulu wa "zambiri, zachangu, zabwino, ndi zachuma" monga kuteteza chilengedwe chobiriwira, kupulumutsa mphamvu ndi kuchepetsa utsi zakhala zikudziwika bwino ndi anthu osiyanasiyana.
Zofunika za njira yomanga:
"ambiri"
● Pogwiritsa ntchito mitundu yosiyanasiyana ya milu monga milu ya nsungwi ndi milu yowonjezereka yophatikizika, komanso njira zowonjezera pansi ndi njira zopangira ma grouting, kuponderezana kwa maziko, kutulutsa, ndi kunyamula kopingasa kumatha kusintha kwambiri;
● Zogwiritsidwa ntchito pazikhalidwe zosiyanasiyana za geological, makamaka maziko a milu okhala ndi katundu wambiri komanso zofunikira zonyamula katundu.
"mwachangu"
● Kugwira ntchito kwa zomangamanga kumakhala kwakukulu, kumiza kwa mulu wa tsiku limodzi la makina amodzi kumatha kufika mamita oposa 300, ndipo phindu lachuma ndilopambana kuposa mitundu ina ya milu;
● Kupyolera muzitsulo zobowola, kusintha kwa chingwe chonyamulira kumatha kudziwika popanda kudula milu;
● Njira yolumikizira makina osavuta, yofulumira komanso yodalirika ingasankhidwe kuti iwonetsetse kudalirika kwa kulumikizana kwa mulu komanso kukonza bwino kwa zomangamanga.
"zabwino"
1. Zida za mulu zimapangidwira mufakitale, ndipo khalidweli ndi lotsimikizika;
2. Kumanga ophatikizidwa, palibe extrusion nthaka, palibe kuwonongeka kwa mulu thupi;
3. Kupanga mwanzeru, kuyang'anira zida zodzitchinjiriza kuonetsetsa kuti zomangamanga zili bwino;
4. Thupi la mulu ndi zolumikizira mulu zimatetezedwa ndi simenti ndi dothi kuti zithandizire kukana dzimbiri;
5. Chitetezo chobiriwira ndi chilengedwe, chimathetsa vuto la kutaya matope pakupanga zomangamanga.
"Province"
Poyerekeza ndi milu yotopetsa pansi pamikhalidwe yomweyi:
1. Kupulumutsa madzi (kusunga madzi omanga 90%);
2. Kupulumutsa mphamvu (kugwiritsa ntchito mphamvu zomanga kungapulumutsidwe ndi 40%);
3. Kuchepetsa umuna (kutulutsa matope kumachepetsedwa ndi 70%);
4. Kusunga nthawi (ntchito yomanga idakwera ndi 50%);
5. Kupulumutsa mtengo (mtengo womanga kupulumutsa 10% -20%);
6. Chepetsani mpweya wotulutsa mpweya ndi 50%.
Poyang'anizana ndi tsogolo, SEMWg adzakhala mwamphamvu cholinga pawiri mpweya cholinga, kupitiriza kulimbikitsa mankhwala wobiriwira, kupanga zobiriwira, zobiriwira zomangamanga, etc., kutsogolera wobiriwira ndi zisathe chitukuko cha makampani, ndi kupitiriza kulenga phindu makasitomala padziko lonse.
