Geomembrane rau Canal Lineing thiab Irrigation System Waterproofing

Engineering-qib hydraulic barrier system tsim los rau kev tswj cov dej seepage, kev txuag dej, thiab kev ua haujlwm ntev -lub sij hawm ua haujlwm ruaj khov nyob rau hauv loj -tej irrigation infrastructure.

Hydraulic Failure Analysis

Vim li cas Irrigation Canals raug kev poob dej tas mus li

Av Permeability Loss

Cov qauv av ntuj muaj qhov sib cuam tshuam qhov pores uas tso cai rau cov seepage tas li. Txawm tias compacted av nplaum txheej tsis tuaj yeem ua tiav xoom permeability nyob rau hauv ntev -lub sij hawm hydraulic siab.

Hydraulic Gradient nyhuv

Cov dej tsis tu ncua ua rau muaj qhov sib txawv ntawm qhov sib txawv uas yuam kom cov dej txav mus rau hauv qab thiab tom qab mus rau hauv subsoil txheej.

Thermal & Qhuav-Wet Cycles

Kev nthuav dav thiab kev cog lus ntawm cov av ua rau micro- cracking, nce seepage paths raws sij hawm.

ENGINEERING SOLUTION

HDPE Geomembrane Canal Lineing System Mechanism

HDPE geomembrane for landfill liner system

HDPE geomembrane ua raws li qhov txuas txuas tsis tu ncua hydraulic thaiv nruab nrab ntawm cov av thiab dej.

Engineering muaj nuj nqi:

Tshem tawm txoj hauv kev ntsug thiab sab nraud
Tsim tag nrho hydraulic sib cais ntawm dej thiab subgrade av
Txhim khu kev khiav hauj lwm zoo los ntawm kev txo cov infiltration poob
Stabilizes kwj dej geometry nyob rau hauv hydraulic loading
Tiv thaiv kev yaig ntawm cov av hauv paus

Tsis zoo li av nplaum liners, geomembranes muab kev tswj permeability zoo ib yam ntawm cov av sib txawv.

SYSTEM STRUCTURE DESIGN

Canal Lineing Multi-Layer Engineering System

Subgrade Av → Compaction Layer → Geotextile Cushion → HDPE Geomembrane → Tiv thaiv txheej (Xuab zeb / pob zeb / Riprap)

Txhua txheej ua haujlwm rau engineering tshwj xeeb:

✔ Subgrade Av: muab cov qauv tsim
✔ Geotextile: tiv thaiv kev sib tsoo thiab ua kom muaj kev sib txhuam ruaj khov
✔ Geomembrane: hydraulic impermeable barrier
✔ Kev Tiv Thaiv Txheej: cov khoom siv tiv thaiv tiv thaiv UV, ntws, thiab cuam tshuam kev ntxhov siab

ENGINEERING PERMANCE DATA

Seepage txo
92% – 98%

Irrigation Efficiency
+30% – 40%

Kev Pabcuam Lub Neej
20-50 Xyoo

Kev kho tus nqi txo
Txog li 60%

INSTALLATION ENGINEERING CONTROL

Field Welding & Quality Assurance System

HDPE geomembrane installation yuav tsum nruj vuam zoo tswj kom ntseeg tau hydraulic kev ncaj ncees.

Cov txheej txheem engineering muaj xws li:
✔ Dual -khiav kub wedge vuam system
✔ Tsis yog -kev ntsuas huab cua tsis zoo
✔ Nqus lub thawv seam soj ntsuam
✔ Kev puas tsuaj tev lub zog sampling

Tag nrho cov weld seams yuav tsum dhau QA / QC cov qauv ua ntej hydraulic loading pib.

ENGINEERING CASE STUDY

Loj -Scale Irrigation Canal Project - Middle East

smooth HDPE geomembrane for waste containment

Qhov project Length: 85 km kwj dej kwj dej

Engineering Challenges:

Siab seepage poob nyob rau hauv sandy av foundation
Lub caij hydraulic fluctuation
Ntev -qhov deb khiav efficiency degradation

Cov txiaj ntsig kawg: ✔ 92% txo cov dej poob
✔ 35% nce hauv hydraulic efficiency
✔ 28% nthuav dav ntawm thaj chaw irrigated farmland
✔ Kev txo qis hauv cov nqi siv dej ua haujlwm
