I. Khoom txhais

EN124 yog ib qho tseem ceeb ntawm EU tus qauv rau manhole npog thiab cov kwj deg hauv cov neeg taug kev thiab tsheb thauj mus los. Nws poob rau hauv EU txoj cai tswj hwm kev sib raug zoo hauv tsev, thiab cov khoom yuav tsum tau ntawv pov thawj CE nkag mus rau European lag luam. Qhov ntsuas A15 yog qhov ntsuas qhov hnyav tshaj plaws, tsim tshwj xeeb rau cov neeg taug kev -ib puag ncig.

Cov duab plaub haum rau cov duab plaub qhov qhib, tso cai rau kev siv qhov chaw yooj yim dua hauv cov kav dej hauv nroog thiab tsim nyog rau cov uas tsis yog - lub voj voog manholes.

II. Yam ntxwv thiab Specifications

EN124 A15 square manhole npog yuav tsum ua kom tau raws li qhov yuav tsum tau muaj xws li kev thauj khoom zoo li qub -cov kabmob muaj peev xwm, cuam tshuam tsis kam, tiv thaiv-kev ua haujlwm tsis zoo, thiab qhov kub thiab txias. Cov qauv tsim saum npoo suav nrog cov khoom tiv thaiv- plam, ua kom muaj kev ruaj khov nyob rau hauv qhov kub thiab txias.

Dimensions yog teev raws li "sab nrauv ncej loj × puab qhib loj × thickness," nrog rau cov qauv square thiab kev cai duab plaub qhov ntau thiab tsawg kom haum ntau qhov ntau thiab tsawg ntawm kev nkag manholes.

III. Cov yam ntxwv ntawm cov khoom tseem ceeb

SMC Composite Khoom

Siv iav fiber ntau thiab unsaturated resin raws li cov khoom siv hauv paus, nrog cov khoom siv hlau sab hauv thiab siab -kub lamination molding, nws cov txiaj ntsig tseem ceeb yog muaj zog tiv thaiv -cov khoom siv tub sab nyiag (tsis muaj cov khoom siv hlau rov ua dua), zoo heev durability (corrosion resistant, xeb-dawb, lub neej ua haujlwm ntev), sealing kev ua tau zoo (tiv thaiv "tsis muaj ntxhiab khiav tawm thiab tsis muaj qhov hnyav, tsis muaj teeb meem kev thauj mus los), cov nqi).

Grey Cam khwb cia hlau / Ductile Iron

Grey cam khwb cia hlau yog tes-cam khwb cia thiab muaj anti{1}}corrosion txheej; ductile hlau muaj zog dua thiab tuaj yeem kho nrog cov txheej tshwj xeeb. Cov txiaj ntsig zoo suav nrog kev cuam tshuam zoo heev, ua rau nws tsim nyog rau thaj chaw uas cov tsheb qee zaus nkag los ntawm qhov yuam kev. Nws tuaj yeem tsim nrog cov qauv hinged kom yooj yim txij nkawm. Cov kev txwv muaj xws li kev pheej hmoo ntawm tub sab nyiag, qhov xav tau ntawm cov cuab yeej xauv, thiab nws qhov hnyav hnyav.

IV. Siv tau Scenarios

Qib A15 feem ntau yog siv rau hauv lub teeb- thaj chaw ua haujlwm yam tsis muaj tsheb thauj mus los, suav nrog kev taug kev hauv nroog, txoj kev taug kev, chaw ua si, thaj chaw ntsuab siv, tsis yog - txoj kab tsheb tsav tsheb, khw muag khoom sab nraum zoov plazas, tsev kawm ntawv chaw ua si, thiab lwm qhov chaw pej xeem lub tsev, nrog rau cov chaw tshwj xeeb 3 chaw ua si, xws li cov chaw ua si hauv chaw ua si, xws li chaw ua si thiab chaw ua si;

Lus Cim: Siv nyob rau hauv txoj kab tsheb tsav tsheb thiab chaw nres tsheb yog nruj me ntsis txwv. Kev thauj khoom siab dua- cov khoom muaj peev xwm yuav tsum raug xaiv rau cov xwm txheej no.

V. Kev txhim kho thiab tu

Installation siv ib tug embedded ncej. Qhov siab sib txawv ntawm lub hau thiab hauv av yuav tsum tau tswj nyob rau hauv ib qho kev tsim nyog. Cov npoo yog tsau nrog pob zeb ua kom tsis txhob txav mus.

Tsis tu ncua xyuas cov sealing kev ua tau zoo thiab bolt nruj. Ntxuav txhua hnub nrog cov tshuaj ntxuav tes kom tsis txhob muaj kev puas tsuaj rau saum npoo.

Cov khoom siv sib xyaw manhole npog yuav tsum tsis txhob sib cuag nrog cov tshuaj corrosive ntev. Cam khwb cia hlau manhole npog yuav tsum tau xyuas tsis tu ncua ntawm txheej kev ncaj ncees.

VI. Kev xaiv thiab kev yuav khoom tseem ceeb

Scenario Matching

Rau cov cheeb tsam uas muaj neeg taug kev nkaus xwb, muab qhov tseem ceeb ntawm SMC cov ntaub ntawv sib xyaw; rau thaj chaw uas yuav muaj tsheb thauj mus los ib ntus, xaiv cov hlau nplaum.

Kev lees paub qhov loj

Ntsuas lub puab ncej qhov ntev ntawm lub manhole qhib thiab tso cai rau tsim nyog installation clearance.

Muaj nuj nqi ntxiv

Rau manholes yuav tsum tau qhib ntau zaus, xaiv cov qauv nrog hinges; rau dej phwj manholes yuav tsum tau txhim khu kev sib khi, xaiv cov khoom uas muaj lub siab sealing tsim.

Kev Ua Raws Cai

Xav kom cov neeg muag khoom muab cov ntawv ceeb toom cuam tshuam thiab cov ntaub ntawv pov thawj CE kom tsis txhob muaj cov ntawv sau cuav.
