Yog li, nws cov khoom siv raw yog dab tsi?

Ib. Cov qauv yooj yim ntawm peb-seem composite dej ntws network

Cov ntaub thaiv dej sib xyaw ua ke peb-seem yog ib hom khoom siv geosynthetic uas muaj peb txheej ntawm cov qauv tshwj xeeb. Nws yog tsim los ntawm cov txheej sab saud thiab sab hauv qab ntawm geotextiles thiab txheej nruab nrab ntawm cov ntaub thaiv dej ntws. Cov txheej txheem tsim khoom ntawm cov ntaub thaiv dej ntws yog qhov tshwj xeeb, siv cov polyethylene siab (HDPE) Ua cov khoom siv raw, nws yog ua los ntawm cov txheej txheem extrusion molding tshwj xeeb. Yog li ntawd, cov ntaub thaiv dej sib xyaw ua ke peb-seem muaj kev ua haujlwm zoo heev, kev ua haujlwm tiv thaiv kev lim dej thiab kev nkag tau huab cua.

2. Kev tshuaj xyuas cov khoom siv raw tseem ceeb

1, Cov polyethylene ceev ceev (HDPE)

Cov polyethylene uas muaj zog heev yog cov khoom siv tseem ceeb ntawm cov kav dej ntws peb-seem. Nws yog cov thermoplastic nrog cov khoom zoo heev thiab kev ruaj khov tshuaj lom neeg. HDPE Tom qab cov khoom siv raw dhau los ntawm cov txheej txheem extrusion molding, cov kav dej ntws nrog cov tav tuab thiab cov tav hla uas teeb tsa rau hauv qhov kev taw qhia ntev tuaj yeem tsim tau. Yog li ntawd, cov kav dej ntws muaj cov kav dej ncaj nraim hauv qhov kev taw qhia ntws, uas kuj tseem tuaj yeem txhim kho qhov ruaj khov tag nrho. HDPE Cov khoom siv kuj muaj kev tiv thaiv kev hnav zoo heev thiab cov khoom tiv thaiv kev laus, uas tuaj yeem ua kom cov dej ntws ua haujlwm ruaj khov ntev.

2, Geotextile

Geotextile yog cov txheej sab saud thiab sab hauv qab ntawm peb-seem sib xyaw ua ke dej ntws, uas feem ntau ua lub luag haujlwm tiv thaiv kev lim dej thiab kev tiv thaiv. Geotextiles feem ntau yog ua los ntawm cov khoom siv fiber ntau xws li polyester fiber thiab polypropylene fiber, uas muaj dej zoo heev permeability, huab cua permeability thiab qee lub zog. Hauv peb-seem sib xyaw ua ke dej ntws network, geotextile tuaj yeem tiv thaiv cov av thiab cov khoom tsis huv los ntawm kev thaiv cov kav dej ntws, thiab tseem tiv thaiv lub hauv paus network dej ntws los ntawm kev puas tsuaj sab nraud. Geotextile kuj muaj qee qhov kev tiv thaiv ultraviolet, uas tuaj yeem ua rau lub neej ua haujlwm ntawm cov dej ntws ntev dua.

3. Kev xaiv thiab kev tswj xyuas zoo ntawm cov khoom siv raw

1. Thaum xaiv cov khoom siv raw ntawm peb-seem composite drainage network, cov khoom siv lub cev, kev ruaj khov tshuaj lom neeg thiab kev hloov pauv ib puag ncig ntawm cov ntaub ntawv yuav tsum tau xav txog tag nrho. HDPE Cov ntaub ntawv raw muaj qhov ceev ceev, lub zog thiab kev tawv, uas tuaj yeem ua tau raws li cov kev xav tau ua tiav thiab kev ua tau zoo ntawm cov dej ntws mesh core. Cov ntaub ntawv Geotextile muaj cov dej permeability zoo heev, huab cua permeability thiab lub zog, nrog rau qee yam khoom tiv thaiv kev laus thiab tiv thaiv ultraviolet.

2. Hais txog kev tswj xyuas zoo, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas thiab sim cov khoom siv raw kom ntseeg tau tias nws ua tau raws li cov qauv thiab cov lus qhia tseem ceeb. Thaum lub sijhawm tsim khoom, nws yog ib qho tsim nyog los txhawb kev tswj hwm ntawm cov dej ntws mesh core thiab geotextile composite txheej txheem kom ntseeg tau tias tag nrho cov kev ua tau zoo thiab ruaj khov ntawm cov khoom.

Daim ntawv thov thiab qhov zoo ntawm peb-seem composite dej ntws network

1, Hauv cov haujlwm txuag dej, nws tuaj yeem siv rau hauv kev ntws dej thiab kev tiv thaiv cov pas dej, cov pas dej, cov dej ntws thiab lwm yam haujlwm;

2, Hauv kev tsim kho tsheb, nws tuaj yeem siv rau hauv kev ntws dej thiab kev txhawb nqa ntawm txoj kev loj, kev tsheb ciav hlau, qhov av thiab lwm yam haujlwm;

3, Hauv kev tsim vaj tsev, nws tuaj yeem siv rau hauv kev ntws dej thiab kev tiv thaiv dej ntawm qab nthab, ru tsev, vaj, thiab lwm yam.

4. Piv nrog cov ntaub ntawv ntws dej ib txwm muaj, cov ntaub thaiv dej sib xyaw ua ke peb-seem muaj qhov zoo ntawm kev ntws dej zoo, kev ua haujlwm lim dej zoo, huab cua permeability zoo thiab kev tsim kho yooj yim. Nws tuaj yeem tiv taus cov khoom siv siab ntev thiab tswj kev ntws dej ruaj khov; Nws kuj muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem ruaj khov hauv cov chaw acid-base.

Raws li pom tau los ntawm saum toj no, cov khoom siv raw ntawm peb-seem composite drainage network feem ntau suav nrog high-density polyethylene (HDPE) Thiab geotextiles. Kev xaiv thiab kev tswj xyuas zoo ntawm cov khoom siv raw no yog qhov tseem ceeb kom ntseeg tau tias muaj kev ua tau zoo thiab ruaj khov ntawm cov dej ntws.
