Geotechnical kev daws teeb meem rau Hydraulic Engineering
Peb muab customized yob dav thiab thicknesses, thiab muab cov ntaub ntawv xam cov kev daws teeb meem rau complex ua hauj lwm tej yam kev mob thoob ntiaj teb.Peb muab customized geotechnical kev daws teeb meem rau dams, canals, thiab cov ntug dej hiav txwv engineering tej yaam num los xyuas kom meej qhov project muaj kev ruaj ntseg, seepage tiv thaiv, thiab durability.
Core conservancy daim ntawv thov thaj chaw
Dam & Reservoir
Pain Points:Nce infiltration kab, piping nyob rau hauv lub pas dej ua ke, thiab structural to.
Kev daws:Siv HDPE geomembrane lossis composite geomembrane. High elongation kom ntseeg tau tias cov khoom tuaj yeem hloov kho kom haum rau lub pas dej thiab deformation, thaum ultra- tsis tshua muaj permeability muab cov dej tsis sib haum.
Canal & Slope
Pain Point:Lub txhab nyiaj yaig thiab av poob los ntawm cov dej ntws.
Kev daws:Siv geocells puv nrog cov av vegetated. Cov qauv honeycomb zoo disperses dej ntws shear kev nyuaj siab thaum kho cov nroj tsuag hauv paus, ua tiav qhov sib npaug ntawm kev tiv thaiv engineering thiab ecological toj roob hauv pes.
Canal Lineing
Pain Point:Channel leakage thiab av particle poob ua rau hauv ob sab phlu delamination.
Kev daws:Tsis yog -woven geotextile li txheej lim. Thaum ua kom cov dej ntws zoo, nws cuam tshuam cov av zoo, tiv thaiv kev yaig thiab tsis ruaj khov ntawm cov channel hauv paus.
Dam seepage tiv thaiv thiab structural reinforcement system
Cov dej siab siab thiab cov dej ntws hauv cov dej loj loj ua rau muaj kev pheej hmoo loj heev. Weiwo muaj siab -tensile- lub zog sib xyaw geomembranes nrog kev sib xyaw "seepage tiv thaiv-kev tiv thaiv" qauv, muaj peev xwm ua kom haum rau kev sib haum xeeb thiab deformation ntawm lub pas dej ua ke thaum lub sij hawm pib impoundment.
Cov ntaub ntawv tseem ceeb:1.5mm + HDPE Geomembrane / 800g + Composite Geomembrane
Cov txiaj ntsig tseem ceeb:Txo cov kab phreatic, tiv thaiv cov kav dej ntawm cov pas dej ua ke, thiab muaj lub neej tsim tshaj 50 xyoo.
Cov txheej txheem hauv ob sab phlu rau ntev -kwj dej thiab thaj chaw dej
Hauv kev ua liaj ua teb irrigation thiab inter- hloov dej hauv pas dej, cov kab xau tuaj yeem ncav cuag li 40%. Peb tsim cov kua dej thiab lub siab nyem los ntawm kev sib txuas ntawm peb -dimensional geonet nrog lub geomembrane los tiv thaiv cov hauv ob sab phlu los ntawm bulging.
Cov ntaub ntawv tseem ceeb:Composite drainage net (GNET) / Geocell
Tus nqi tseem ceeb:Ua tiav ntau dua 98% kev tiv thaiv kev tiv thaiv kev ua haujlwm, txo cov channel tu zaus.
Ecological txoj kab nqes kev tiv thaiv thiab scour tswj
Cov tsoos pob zeb revetments puas ecosystem. Weiwo geocells muab cov cuab yeej siv dag zog thaum tso cov nroj tsuag kev loj hlob, nqus dej ntws shear zog, thiab kho tus dej tus kheej -purification peev.
Core Khoom:Siab -lub zog HDPE geocells / Cov hnab zaub
Tus nqi tseem ceeb:Resistant mus rau dej ntws ceev tshaj 5 m / s, sai tsim ntsuab ecological shorelines.
Kev sib piv ntawm kev ua tau zoo ntawm cov khoom siv rau kev txuag dej
Cov ntaub ntawv siv raws li cov qauv ntsuas thoob ntiaj teb ASTM / ISO
| Daim ntawv thov Scenario | Khoom siv pom zoo | Core Physical Properties | Critical Engineering Solutions |
| Reservoir & Dam Seepage Control | Composite Geomembrane (Ib sab Geotextile-bonded) | Elongation ntawm Break> 600% / Permeability Coefficient < 1.0 × 10⁻¹³ cm/s | Tiv thaiv Phreatic Kab los ntawm kev nce siab dhau lawm, txo qhov kev pheej hmoo ntawm kev ua txhaum dej los yog kav dej. |
| Riverbank & Slope Protection | HDPE Geocell (Cellular Confinement System) | Kev sib tshuam Peel Strength> 1400 N / 10cm | Confines av tiv thaiv yaig; txhawb nqa cov nroj tsuag loj hlob nyob rau hauv siab - nrawm hydraulic ntws. |
| Filtration & Subsurface Drainage | Filament Non{0}}woven Geotextile | Qhib Qhov Loj (O95): 0.07–0.2 mm | Ua kom dej paug tawm thaum tiv thaiv kev tsiv teb tsaws ntawm cov av zoo (Filtration Principle). |
| Mos Av Foundation Stabilization | Woven Geotextile / Steel -Plastic Geogrid | Tensile zog: 50 kN / m - 100 kN / m | Ua kom cov kabmob muaj peev xwm thiab faib cov khoom thauj kom tsis txhob muaj av zawv zawg thiab sab nraud tawm. |
ProfessionalHydraulic EngineeringFAQ
Yuav ua li cas tiv thaiv geomembrane los ntawm raug punctured los ntawm cov pob zeb ntse hauv qab dej siab?
Peb cov kev daws teeb meem yog "sandwich" qauv: siab -grammage (piv txwv li, 400g / m² lossis siab dua) ntev -filament nonwoven geotextile yog nteg rau saum thiab hauv qab ntawm HDPE geomembrane. Cov geotextile ua raws li cov txheej txheem tsis, nqus cov kev ntxhov siab hauv cheeb tsam thiab tiv thaiv cov seepage - cov ntaub ntawv pov thawj los ntawm kev puas tsuaj.
Yuav ua li cas ntsuas qhov vuam zoo ntawm kwj dej seepage tiv thaiv tej yaam num?
Peb nruj me ntsis ua raws li cov txheej txheem "ob-seam air pressure testing". Ib qho cua kab noj hniav yog tshwj tseg ntawm ob lub weld seams, thiab lub siab poob yog pom tom qab pressurization. Tsis tas li ntawd, kev ntsuas lub tshuab nqus tsev yog siv rau thaj chaw nyuaj. Peb tuaj yeem xa cov kws tshaj lij kev paub dhau los los muab rau ntawm - qhov kev taw qhia ntawm qhov chaw kom ntseeg tau tias xoom - qhov kev xa khoom tsis raug.
Weiwo's geocells puas puas yuav degrade nyob rau hauv ntev - immersion nyob rau hauv dej?
Tsis yog kiag li. Peb siv cov khoom siv antioxidant nkauj xwb HDPE thiab ntxiv cov pa roj carbon tshwj xeeb, uas muaj zog tiv taus acids, alkalis, thiab UV rays. Txawm hais tias nyob rau hauv ib puag ncig nrog kev hloov pauv ntawm cov dej hauv dej, nws lub neej kev pabcuam tuaj yeem ncav cuag ntau dua 70 xyoo.
Cov txheej txheem thoob ntiaj teb twg koj cov khoom ua tau raws li?
Peb cov khoom ua tau raws li GRI-GM13 (HDPE), ASTM D cov qauv, thiab daim ntawv pov thawj CE. Peb muaj CNAS- qhov chaw kuaj pom zoo, thiab txhua pawg ntawm cov khoom tuaj nrog daim ntawv qhia txog lub Hoobkas ua tiav.
