Professional qhov av geotechnical daws
Rau qhov hauv ob sab phlu, kev txhawb nqa, thiab kev tsim cov dej ntws tawm, Weiwo muab cov khoom ua tiav ntawm cov khoom siv geotechnical los pab daws cov teeb meem hauv engineering xws li dej siab seepage, av deformation, thiab kev qaug zog ntawm cov qauv.
Peb qhov teeb meem loj tau ntsib los ntawm kev tsim kho qhov av
Weiwo tau sau ntau qhov kev paub dhau los los muab kev tiv thaiv kev tiv thaiv rau tag nrho lub neej voj voog ntawm tunnels.
1. Dej tsis ua hauj lwm thiab hauv ob sab phlu Corrosion
Cov dej siab ntev ntev tuaj yeem yooj yim ua rau calcium nag lossis daus hauv cov pob zeb ua vaj tse thiab corrosion ntawm cov hlau reinforcing. Peb qhov kev tiv thaiv kev sib xyaw ua ke muab qhov "zero-permeability" lav.
2. Instability thiab Deformation ntawm Tsis muaj zog puag ncig pob zeb
Nyob rau hauv cov av mos strata, tsis txaus lub hauv paus bearing peev xwm yuav ua rau tunnel qauv kev sib haum xeeb. Siab - zog geogrids tuaj yeem txwv cov pob zeb hloov chaw nyob ib puag ncig.
3. Adhesion ntawm Shotcrete nyob rau hauv Thawj Kev Txhawb
Los ntawm tshwj xeeb tsim geogrids, cov neeg kho tshuab interlocking ntawm pob zeb thiab pob zeb nto yog txhim kho, txo tus nqi rov qab thiab txhim kho kev txhawb zog.
EVA / PVC geomembrane
• Zoo heev puncture kuj
• Superior ductility, adaptable rau cov pob zeb tsis sib xws
• Yooj yim rau cua sov weld, ua kom muaj kev sib khi ua ke
Tunnel composite drainage network
• Khaws cov dej conductivity zoo dua nyob rau hauv siab
• Hloov cov khaubncaws sab nraud povtseg ntawm cov pob zeb tsoos, txo qhov kev hla- ntu
• Tiv thaiv kom zoo particle clogging, mus tas li tus kheej - ntxuav
Tshwj xeeb ntev -filament nonwoven geotextile
• Ua hauj lwm raws li ib tug tsis thiab lim txheej nyob rau hauv lub waterproofing txheej
• Siab- tsim muaj zog tiv thaiv kev puas tsuaj
• Resistant mus rau alkaline ib puag ncig (rau pob zeb effluent)
Core Performance Parameters ntawm tunnel khoom
| Performance Indicator | Hwm Standard (Premium) | General Kev Lag Luam Standard | Qhov tseem ceeb rau Engineering |
|---|---|---|---|
| Tensile zog (Longitudinal / Transverse) | Ntau dua lossis sib npaug li 25 MPa | 15-18 MPa | Tiv thaiv kev puas tsuaj thaum lub sij hawm tsim kho |
| Kub Melt Lap Shear Strength | 95% ntawm cov khoom siv dag zog | Kwv yees li 80% | Xyuas kom tsis txhob muaj dej ntws hauv qab dej siab |
| Anti-Tshuaj Kev Pabcuam Kev Laus Lub Neej | >100 xyoo | 30-50 xyoo | Ua kom tsis muaj kev hloov pauv thaum lub sijhawm ua haujlwm puv sijhawm |
Peb cov kev daws teeb meem tsis yog tsuas yog hais txog cov khoom siv, tab sis kuj tseem hais txog kev ua kom muaj kev ruaj ntseg engineering.
- Kev them nyiaj yug tag nrho Lifecycle: Los ntawm kev sib tham txog kev xaiv cov ntaub ntawv mus rau ntawm - qhov chaw vuam kev taw qhia.
- Customization: Peb tuaj yeem tsim cov ntaub thaiv dej tsis zoo rau 8 meters dav, txo cov seams thiab txo qhov kev pheej hmoo ntawm cov dej xau.
- Teb sai: Rau cov haujlwm kho thaum muaj xwm txheej ceev, peb muab kev lav 48-teev xa khoom thoob ntiaj teb.
