Nyob rau hauv tej yam kev mob ntawm ib tug suburban cheeb tsam los yog suburban cheeb tsam, nws yog ib qho tsim nyog yuav tau daws cov teeb meem cuam tshuam nrog rau kev npaj cov txheej txheem rau kev tso dej ntau dhau los nag thiab dej hauv av. HDPE cov kav dej yog cov khoom tsim nyog tshaj plaws rau kev teeb tsa ntawm qhov system.
Daim ntawv thov
HDPE-pipe yog siv los txhim kho cov dej ntws ntawm cov hav zoov thiab cov chaw ua liaj ua teb, hauv thaj chaw ntawm cov chaw ua kis las, hauv kev tsim kho, hauv kev teeb tsa ntawm thaj chaw toj roob hauv pes thiab tiv thaiv hauv qab daus, nrog rau cov hauv paus ntawm cov tsev. rau ntau lub hom phiaj.
Key Features
Cov kav dej ua los ntawm HDPE yog SN4 hardness chav kawm. Lawv sib sib zog nqus los ntawm 4 m. Ib lub bay tuaj yeem hnyav txog 30 kg, qhov tsawg kawg nkaus tus nqi yog 24 kg. Qhov ntev ntawm cov yeeb nkab yog 50 m. Qhov siab thiab txoj kab uas hla ntawm lub kauj yog sib npaug li 0.7 thiab 1.5 m, raws li. Cov dej ntws tau muab tso rau hauv cov cheeb tsam uas cov av muaj cov qib siab ntawm cov dej hauv av.
Cov kav dej no qhuav tawm saum av. Cov khoom lag luam asbestos-cement tau nce ntxiv los ntawm cov yas, vim HDPE yog cov khoom siv ruaj khov, txhim khu kev qha thiab kev lag luam. HDPE cov kav dej tsis rot, tsis raug tawm tsam los ntawm cov tshuaj thiab tuaj yeem tso tau txawm tias huab cua txias yam tsis muaj kev puas tsuaj rau cov kav dej.
yam ntxwv ntawm hom perforation
Hnub no, cov kav dej piav qhia tau muab muag nrog ntau qib ntawm perforation. Yog hais tias nws nyob rau hauv tag nrho cov nto, ces koj yuav pom tus naj npawb 360 nyob rau hauv lub cim, xws li cov khoom yog siv nyob rau hauv cov cheeb tsam uas muaj ib tug ntau impressive nqi ntawm av.
Xaiv cov kav dej nrog 240 ° perforation, koj tau txais cov khoom lag luam, lub qhov ntawm qhov chaw uas nyob hauv qee ntu ntawm lub voj voog. Ib feem ntawm cov yeeb nkab yuav raug perforated, thaum lwm qhov yuav nyob twj ywm. Yog tias koj nruab cov kav dej nrog kev pab ntawm cov kav dej, koj yuav tuaj yeem coj cov dej ntws los ntawm txoj kab nqes.
Ntxiv cov lus qhia
Drainage HDPE kav yog ua los ntawm polyethylene qib PE80 SDR 17. Nws ua raws li GOST 18599-2001. Raws li SDR tus qauv, cov khoom tau piav qhia muaj qee qhov ntev, phab ntsa thickness thiab txoj kab uas hla. Rau kev npaj ntawm cov kav dej, qhov tsawg kawg nkaus txoj kab uas hla yog 50 hli, thaum tus nqi siab tshaj plaws yog 200 hli.
Hnub no, ntawm kev ua lag luam rau cov khoom siv sib xws, koj tuaj yeem pom ntau yam ntawm cov kav dej tau piav qhia, lawv yuav muajib nrab lossis ua tiav perforation. Cov kav dej yog insulated nrog geotextile lossis lwm yam khoom siv lim, tab sis tej zaum yuav tsis muaj nws. Yog tias peb tab tom tham txog cov khoom lag luam ob txheej, ces lawv tau tsim los siv txoj kev co-extrusion.
Corrugations nyob rau saum txheej thiab tau txais txiaj ntsig nrog cov tav tav. Qhov no ua rau lawv muaj zog heev. Sab hauv cov kav dej yog du, qhov no guarantees slipping. HDPE cov kav dej tuaj yeem muaj qhov sib txawv ntawm qhov perforation, uas yog xaiv los ntawm kev ua haujlwm ntawm cov kav dej.
Yog tias cov av yuav tsum tau ntws thiab nws cov dej noo tswj, cov khoom siv nrog thaj tsam loj perforation yog siv. Ntawm no koj yuav tsum coj mus rau hauv tus account lub fact tias lub qhov yuav nyob ntawm 240 mus rau 360 ° nyob rau saum npoo. Yog tias cov dej ntws tau nruab kom tshem tawm cov dej noo los ntawm cov av saum npoo, ces cov qhov tuaj yeem nyob rau hauv ib qho chaw nrog lub kaum sab xis txog li 180 ° C.
Thaum cov av ntawm qhov chaw yog clayey, ces muab cov kav dej ua ntej tso rau hauv. Geotextile yog li tsis suav nrog dej nyab ntawm cov kav dej thiab ua rau nws ua haujlwm tau zoo dua. Corrugated HDPE cov kav dej yuav muaj qhov me me 180 ° perforated seem. Cov khoom zoo li no yog siv rau hauv qhov chaw uas yaj thiab dej hauv av sib sau ua ke ntau.
Rau qhov dej ntws, cov kav dej nrog 120 ° perforations yuav tsum tau siv. Qhov kev hloov kho no tshwj xeeb yog tsim los rau cov tshuab zoo li no. Cov kav dej uas tsis tshua muaj siab polyethylene muaj peev xwm hloov tau dej atmospheric los ntawm qhov chaw thiab tsis suav nrog qhov nce ntawm cov dej hauv av mus rau lub hauv paus ntawm lub tsev. Pwm yuav tsis tsim nyob rau hauv cov tsev nyob rau hauv ib cheeb tsam, thiab hauv qab daus plag tsev yuav tsisdej nyab.
yam ntxwv ntawm geotextile kav
HDPE cov kav dej nrog geotextile yog nthuav tawm hauv ib txheej thiab ob txheej khoom. Txoj kab uas hla tuaj yeem sib npaug ntawm qhov txwv ntawm 50 mus rau 200 mm. Cov nqi nruab nrab yog:
- 90mm;
- 110 mm;
- 125mm;
- 160 mm.
Lub hauv paus yuav yog cov npe sib txawv ntawm cov khoom tuaj txawv teb chaws thiab hauv tsev polyethylene. Ntawm cov khoom siv lub cev thiab cov khoom siv kho tshuab, nws tsim nyog hais txog qhov cuam tshuam tsis zoo, uas yog 10, nrog rau lub nplhaib nruj, uas yog 4 kPa.
Peb kuj yuav tsum hais txog qhov ceev, uas yog sib npaug rau 0.93 g / cm3. Thaum xaiv cov khoom, cov neeg siv khoom kuj tau them nyiaj rau lub zog tensile tawm los, nws ncav cuag 16.7 MPa.
Qhov hnyav thiab qhov dav ntawm lub kauj yuav nyob ntawm qhov kab ntawm cov yeeb nkab sab nraud thiab sab nraud ntawm lub kauj, nrog rau tus lej ntawm cov yeeb nkab. Piv txwv li, yog hais tias lub sab nraud txoj kab uas hla ntawm cov khoom yog 90 hli, thiab sab nraud txoj kab uas hla ntawm lub kauj yog 1.14 m, ces lub kauj yuav hnyav 20 kg nrog ib tug dav ntawm 0.5 m. 50 m ntawm cov yeeb nkab yog nkag rau hauv ib kauj.
Txoj hlua ntawm lub lim
Drainage yeeb nkab HDPE nrog perforation nyob rau hauv lub lim yog ib yam khoom uas muab nyob rau hauv ib tug bay ntawm 50 m. Lub puab txoj kab uas hla yog 110 hli. Cov yeeb nkab yog npaj rau kev npaj ntawm kab rov tav kaw cov kua dej nyob rau hauv cov xwm txheej ntawm irrigated plots thiab drained av. Cov dej ntws tau pom nws qhov kev faib tawm hauv kev tsim kho, nrog rau kev xav tau los tiv thaiv hauv qab daus thiab cov hauv paus ntawm cov tsev los ntawmdej.
Cov yeeb nkab yog siv rau hauv kev ua liaj ua teb thiab kev tsim kho vaj tse. Geotextiles yog tsim nyog los tiv thaiv clogging ntawm kab noj hniav thiab cov yeeb nkab qhov nrog av hais thiab xuab zeb. Qhov no pab tiv thaiv silting thiab clogging ntawm cov khoom. Perforation txhawb nqa cov dej ntws mus rau hauv cov yeeb nkab. Cov kua dej tso rau hauv qhov tob ntawm 2 m. Koj tuaj yeem paub nws los ntawm cov ntawv luv DGT, uas sawv cev rau cov kav dej corrugated.
Nyob hauv kaw
Cov kav dej HDPE 160 mm, tus nqi yog 5800 rubles. rau ib yob ntawm 50 m, ua raws li ib qho tseem ceeb ntawm cov txheej txheem uas tshem tawm cov dej ntau dhau ntawm qhov chaw. Cov khoom uas hais txog yog muab tso rau hauv lub lim, uas tso cai rau koj tso rau hauv av thiab tsis txhob ntshai tias clogging yuav tshwm sim.
