中文MJS nzira murwi(Metro Jet System), inozivikanwawo seyese-kutenderera yakakwira-kudzvanya jetting nzira, yakatanga kugadzirwa kugadzirisa matambudziko ekuyerera kwetsvina uye kukanganisa kwezvakatipoteredza mukuita kweyakachinjika rotary jet kuvaka.Parizvino inonyanya kushandiswa kurapa kwenheyo, kurapwa kwekuvuza uye matambudziko emhando yegomba rekuchengetedza mvura-kumisa keteni, uye kurapwa kwemvura inoyerera pamadziro ekunze echivakwa chepasi.Nekuda kwekushandisa yakasarudzika porous pombi uye kumberi-kumagumo kumanikidzirwa slurry kusveta zvishandiso, kumanikidza slurry kubuda mugomba uye pasi pevhu kudzvanywa kwekutarisa kunoonekwa, uye pasi pevhu rinodzorwa nekugadzirisa kumanikidza slurry kubuda vhoriyamu, kuitira kuti yakadzika madhaka kubuda uye kudzvanywa kwepasi kunodzorwa zvine musoro, uye kudzvanywa kwepasi kunogadziriswa, izvo zvinoderedza mukana wekushanduka kwepamusoro panguva yekuvaka uye kunoderedza zvakanyanya kukanganisa kwezvakatipoteredza.Kuderedzwa kwekumanikidzwa kwepasi zvakare kunosimbisa dhayamita yemurwi.
Pre-control
Kubva paMJS murwitekinoroji yekuvaka yakaoma uye yakaoma kupfuura dzimwe nzira dzekugadzira, zvinodikanwa kunyatso kutevedzera zvinodiwa zvekugadzira panguva yekuvaka, kuita basa rakanaka rekuenderana tekinoroji uye kuchengetedza muchidimbu, uye kutevedzera zvinoenderana nemaitiro ekushanda kuti uve nechokwadi chemhando yekuvaka. .
Mushure mekunge chigadziko chekuchera chiri panzvimbo, nzvimbo yemurwi inofanira kudzorwa zvakanaka.Kazhinji, kutsauka kubva panzvimbo yekugadzira hakufaniri kudarika 50mm, uye kutsauka kwakamira hakufaniri kudarika 1/200.
Pamberi pekuvakwa kwepamutemo, kudzvanywa uye kuyerera kwemvura yakakwira-kumanikidza, yakakwira-kumanikidza grouting pombi uye mhepo compressor, pamwe nekusimudza kumhanya, grouting vhoriyamu, uye yekupedzisira gomba mamiriro epombi yegrouting panguva yejekiseni inotsanangurwa kuburikidza nekuyedzwa. mirwi.Munguva yekuvaka kwakarongeka, iyo centralized manejimendi console inogona kushandiswa otomatiki yekutevera uye kutonga.Ita marekodhi akadzama eakasiyana marekodhi ekuvaka pane saiti, anosanganisira: kudhirowa, kudzika kudzika, zvipingamupinyi zvekuchera, kudonha, kushanda paramita panguva yejekiseni slurry, slurry kudzoka, nezvimwewo, uye siya kiyi yemufananidzo data.Panguva imwe cheteyo, zvinyorwa zvokuvaka zvinofanira kurongwa munguva, uye zvinetso zvinofanira kushumwa ndokubatwa nenguva.
Kuti ive nechokwadi chekuti hapana kuputsika kwemurwi kana chibooro chabviswa kana basa rikavhiringwa kwenguva yakareba nekuda kwezvimwe zvikonzero, kureba kwepamusoro uye kwepasi mirwi kazhinji kusiri pasi pe100mm kana jekiseni remazuva ese rinotangwazve. .
Chengetedza muchina wekuvaka usati wavaka kuti uderedze matambudziko emhando anokonzerwa nekutadza kwemidziyo panguva yekuvaka.Kuitisa pre-kuvaka dzidziso yevashandisi vemichina kuti vajairane nemashandiro uye mashandisirwo emidziyo.Panguva yekuvaka, munhu akazvipira ane mutoro wekushanda kwemidziyo.
Kuongorora kusati kwavakwa
Kusati kwavakwa, zvigadzirwa, michina nemidziyo, uye kupfapfaidza maitiro zvinofanirwa kuongororwa, kunyanya mune zvinotevera zvinhu:
1 Zvitupa zvemhando uye mishumo yekuyedza yezvapupu zvezvakasiyana zvigadzirwa (kusanganisira simende, nezvimwewo), kusanganisa mvura kunofanirwa kusangana nemirairo inoenderana;
2 Kunyangwe iyo slurry mix ratio yakakodzera kune chaiyo ivhu mamiriro eprojekiti;
3 Kana muchina nemidziyo zvakajairika.Isati yavakwa, iyo MJS yose-yakakomberedza yakakwirira-kumanikidza rotary jet midziyo, gomba drilling rig, high-pressure dope pombi, slurry mixing background, pombi yemvura, nezvimwewo inofanira kuongororwa uye kumhanya, uye drill rod (kunyanya multiple drill rods) , drill bit and guide device inofanira kunge isina kuvharwa;
4 Tarisa uone kana iyo nzira yekupfapfaidza yakakodzera kune geological mamiriro.Pamberi pekuvakwa, iyo process test spraying inofanirawo kuitwa.Kupfapfaidza kwekuyedza kunofanirwa kuitwa panzvimbo yekutanga murwi.Nhamba yebvunzo yekupfapfaidza mirwi makomba haifanire kunge isingasviki maburi maviri.Kana zvichidikanwa, gadzirisa maitiro ekupfapfaidza maitiro.
5 Kusati kwavakwa, zvipingamupinyi zvepasi zvinofanira kuongororwa zvakafanana kuti zvive nechokwadi chokuti kuchera uye kupfapfaidza kunosangana nezvinodiwa zvekugadzira.
6 Tarisa kurongeka uye kunzwisiswa kwenzvimbo yemurwi, gauge yekumanikidza uye mita yekuyerera isati yavakwa.
In-process control
Panguva yekugadzira, zvinotevera zvinofanirwa kutariswa kune:
1 Tarisa kudzika kwetsvimbo yekuchera, kumhanya kwekuchera, kudzika kwekuchera, kumhanya kwekuchera uye nekutenderera kwekutenderera chero nguva kuti uone kuti zvinopindirana here nezvinodiwa zvepiko rekuongorora rondedzero;
2 Tarisa iyo simende slurry musanganiswa reshiyo uye kuyerwa kwezvinhu zvakasiyana-siyana uye zvinosanganiswa, uye rekodha zvechokwadi kudzvanywa kwejekiseni, kumhanya kwejekiseni uye vhoriyamu yejekiseni panguva yejekiseni grouting;
3 Kana zvinyorwa zvokuvaka zvakakwana.Marekodhi ekuvaka anofanirwa kurekodha kudzvanywa uye kuyerera data kamwe yega yega 1m yekusimudza kana pakusangana kweivhu layer inochinja, uye siya data yemufananidzo kana zvichidikanwa.
Post-control
Mushure mokunge kuvakwa kwapera, ivhu rakasimbiswa rinofanira kuongororwa, kusanganisira: kuvimbika uye kufanana kwevhu rakasimbiswa;iyo dhayamita inobudirira yevhu rakasanganiswa;iyo simba, avhareji yedhayamita, uye nzvimbo yepakati pemirwi yevhu rakabatanidzwa;kusamira kwevhu rakabatanidzwa, nezvimwewo.
1 Quality yekuongorora nguva uye zvirimo
Sezvo simende kusimba kwevhu kunoda imwe nguva yenguva, kazhinji kupfuura mazuva makumi maviri nemasere, izvo zvinodiwa zvinofanirwa kuenderana nemagwaro ekugadzira.Nokudaro, kuongororwa kwehutano hweMJS sprayingkuvaka kunofanira kuitwa kazhinji mushure mekunge MJS high-pressure jet grouting yapera uye zera rinosvika panguva yakatarwa mukugadzira.
2 Hunhu hwekuongorora huwandu uye nzvimbo
Huwandu hwenzvimbo dzekuongorora i1% kusvika 2% yehuwandu hwemakomba ekupfapfaidza ekuvaka.Pamapurojekiti ane maburi asingasviki makumi maviri, poindi imwe chete inofanira kuongororwa, uye ayo anenge akundikana anofanira kumwayiwa zvakare.Nzvimbo dzekuongorora dzinofanirwa kurongerwa munzvimbo dzinotevera: nzvimbo dzine mitoro mikuru, mirwi yepakati pemirwi, uye nzvimbo idzo mamiriro asina kujairika anoitika panguva yekuvaka.
3 Nzira dzekuongorora
Kuongororwa kwejet grouting piles kunonyanya kuongorora midziyo yemuchina.Kazhinji, indekisi yesimba rekumanikidza yevhu resimende inoyerwa.Muenzaniso unowanikwa nekuchera uye coring nzira, uye inogadzirwa kuita yakajairwa bvunzo chidimbu.Mushure mekusangana nezvinodiwa, yemukati yemuviri uye yemuchina yekuongorora zvivakwa inoitwa kuti itarise kufanana kweivhu resimende uye michina yayo.
