Triaxial Geogrid rau Railway Sub -Ballast Stabilization

Advanced Ground Reinforcement Solution rau Modern Railway Infrastructure

Rail sub- cov khaubncaws sab nraud povtseg ua lub luag haujlwm tseem ceeb hauv kev faib cov khoom thauj, tswj xyuas cov duab geometry, thiab tiv thaiv ntev -kev sib hais haum. Raws li kev rov ua haujlwm tsis tu ncua los ntawm kev siab - nrawm thiab hnyav- tsheb ciav hlau, cov txheej txheem granular feem ntau raug kev txom nyem los ntawm kev sib kis ntawm sab nraud, kev puas tsuaj ntawm cov khoom, thiab qhov sib txawv.

Triaxial geogrid muajmuab kev ua haujlwm siab -kev ua tau zoo los ntawm kev txhim kho tus cwj pwm ntawm cov khoom siv hluav taws xob ntawm sub- ballast txheej los ntawm ntau- kev coj mus kaw thiab kev xa khoom thauj.

Vim li cas Sub-Ballast Stabilization yog qhov tseem ceeb hauv Railway Engineering

Hauv kev tsheb ciav hlau, sub- txheej ballast ua raws li kev hloov pauv ntawm ballast thiab subgrade. Txawm li cas los xij, tsis muaj kev txhawb nqa, ntau yam teeb meem tuaj yeem tshwm sim:

• Progressive deformation nyob rau hauv cyclic loading
• Txo cov kabmob muaj peev xwm ntawm tsis muaj zog subgrade
• Kev tu ntau zaus (tamping, ballast renewal)
• Kev ywg dej thiab dej tsis zoo

Cov kev cov nyom no cuam tshuam ncaj qha mus taug qab kev nyab xeeb, tus nqi ntawm lub neej, thiab kev ua haujlwm tau zoo.

Yuav ua li cas Triaxial Geogrid Txhim Kho Sub-Ballast Performance

Tsis zoo li biaxial geogrids,triaxial geogridsfeature ib daim duab peb sab aperture, ua kom muaj zog sib xws thiab kev thauj mus los hauv txhua qhov kev qhia.

Mechanisms tseem ceeb:

1. Ntau-Kev taw qhia kev kaw cia

Daim duab peb sab geometry muab 360℃aggregate interlock, txwv lateral txav ntawm sub-ballast hais nyob rau hauv dynamic loads.

2. Load Distribution Optimization

Log loads tau zoo faib thoob plaws cheeb tsam, txo kev ntxhov siab nyob rau hauv subgrade.

3. Txhim kho Shear Resistance

Txhim kho kev sib cuam tshuam nce shear lub zog ntawm cov granular txheej, tseem ceeb rau kev tsheb ciav hlau ruaj khov.

4. Txo Rutting thiab daws teeb meem

Ntev - lub sij hawm deformation yog txo kom tsawg, tswj cov geometry raws sij hawm.

Tuam Tshoj Triaxial Geogrid Chaw tsim tshuaj paus, lwm tus neeg, Hoobkas

Raws li kev cojTriaxial Geogrid tuam ntxhab nyob rau hauv Suav teb, peb muab cov kev daws teeb meem zoo tshaj plaws geosynthetic uas txhim kho hauv av ntxiv rau cov tsis muaj zog subgrades. Peb cov khoom featuredaim duab peb sab apertures rau ntau- kev taw qhia load faib, kom ntseeg tau superior aggregate interlock thiab uniform kev ntxhov siab hloov. Cov txiaj ntsig tseem ceeb muaj xws li:

Txhim kho Subgrade Stability- Txo qhov sib txawv ntawm qhov sib txawv thiab tiv thaiv kev nkag mus rau hauv cov av mos.

Multi-Kev taw qhia Load Distribution- Isotropic txhav faib cov khoom sib npaug, txhim kho txoj kev taug kev thiab cov txheej txheem txheej txheem.

Siab zog & Durability- Ua nrog hwm siab -modulus polypropylene, nrog rau kev sib txuas ua ke uas tswj cov qauv kev ncaj ncees nyob rau hauv cov tsheb hnyav.

Txo lub hauv paus Thickness & Kev tsim kho tus nqi- Kev siv dag zog zoo tso cai rau cov khaubncaws sab nraud povtseg uas tsis muaj zog.

Kev siv ntau yam- Haum rau txoj kev, embankments, industrial yards, thiab cov av nyuaj thoob ntiaj teb.
