Khoom Taw Qhia
Cov cuab yeej positioning:
Safe Tunneling Technology nyob rau hauv Heterogeneous av
Geological mob:
Cov av mos, cov txheej txheem sib txawv (xuab zeb, gravel, siab permeability thiab dej siab)
NPD series yeeb nkab jacking tshuab yog tsuas yog haum rau geological tej yam kev mob nrog siab av hauv av siab thiab siab av permeability coefficient. Lub excavated slag yog pumped tawm ntawm lub qhov nyob rau hauv daim ntawv ntawm cov av nkos los ntawm cov av nkos twj tso kua mis, yog li nws muaj cov yam ntxwv ntawm kev ua hauj lwm efficiency thiab huv si chaw ua hauj lwm.
Raws li kev sib txawv ntawm kev tswj cov av nkos ntawm qhov chaw khawb av, NPD series yeeb nkab jacking tshuab tuaj yeem muab faib ua ob hom: hom kev tswj ncaj qha thiab hom tswj tsis ncaj (cua cua siab sib xyaw hom tswj).
ib. Cov kev tswj ncaj qha hom yeeb nkab jacking tshuab tuaj yeem tswj kev ua haujlwm siab ntawm cov av nkos tank los ntawm kev kho qhov ceev ntawm cov av nkos twj tso kua mis lossis kho qhov qhib ntawm cov av nkos tswj valve. Txoj kev tswj no yog qhov yooj yim thiab yooj yim, thiab tus nqi tsis ua haujlwm tsawg.
b. Lub indirect tswj yeeb nkab jacking tshuab indirect adjusts lub siab ua hauj lwm ntawm av nkos tank los ntawm kev hloov lub siab ntawm lub cua cushion tank. Txoj kev tswj no muaj cov lus teb rhiab heev thiab kev tswj xyuas siab.
1. Lub tshuab tsis siv neeg tswj cua cushion tuaj yeem muab kev txhawb nqa meej rau lub ntsej muag qhov taub, thiaj li ua kom muaj kev nyab xeeb ntawm kev tsav tsheb mus rau qhov loj tshaj.
2. Tunneling kuj tseem tuaj yeem nqa tawm thaum cov dej siab siab tshaj 15bar.
3. Siv cov av nkos ua qhov nruab nrab nruab nrab kom sib npaug ntawm qhov tsim siab ntawm qhov khawb ntawm qhov av, thiab tso cov slag los ntawm cov av nkos.
4. NPD series yeeb nkab jacking tshuab yog tsim rau kev tsim kho qhov av nrog cov dej siab thiab kev sib haum xeeb hauv av siab.
5. Kev tsav tsheb siab, kev nyab xeeb thiab txhim khu kev qha, nrog ob hom kev sib npaug ntawm kev tswj ncaj qha thiab kev tswj tsis ncaj.
6. NPD series yeeb nkab jacking tshuab nrog siab heev thiab txhim khu kev qha cutter taub hau tsim thiab av nkos.
7. NPD series yeeb nkab jacking tshuab txais yuav txhim khu kev qha lub ntsiab bearing, lub ntsiab tsav foob thiab lub ntsiab tsav reducer, nrog rau kev pab lub neej ntev thiab muaj kev ruaj ntseg zoo.
8. Tus kheej-tsim tswj software system, kev ua haujlwm ntawm tag nrho lub tshuab muaj kev nyab xeeb thiab txhim khu kev qha, thiab kev ua haujlwm yooj yim.
9. Dav siv tau ntau yam av, xws li cov av mos, av nplaum, xuab zeb, gravel av, tawv av, backfill, thiab lwm yam.
10. Independent dej txhaj, tso tawm system.
11. Qhov ceev tshaj plaws yog ze li ntawm 200mm ib feeb.
12. Kev tsim kho ntawm high precision, steering tej zaum qhov nce, nqis, sab laug thiab sab xis, thiab lub kaum sab xis feem ntau yog 5.5 degrees.
13. Siv lub hauv paus tswj hwm hauv av, nyab xeeb, nkag siab, thiab yooj yim.
14. Cov kev daws teeb meem ntawm cov neeg tsim khoom tuaj yeem muab rau cov kev xav tau sib txawv.
