Cov kav dej PE feem ntau muab faib ua ob hom kev tsim kho: kev tsim kho qhov chaw thiab tsis muaj kev tsim kho hauv cov dej hauv nroog thiab cov dej ntws. Niaj hnub no, PE yeeb nkab manufacturers feem ntau piav qhia txog kev tsim kho ntawm slotted nteg.
(1) Ua ntej, ua tib zoo saib xyuas cov kev qhia tshwj xeeb ntawm cov kav dej tso rau raws li cov kev cai cuam tshuam thaum tsim kho, thiab ua kev soj ntsuam raws li cov qauv khoom, thiab tshem tawm cov kav dej uas tsis ua raws li cov qauv. Yog tias lub raj xa dej tau muab tso rau hauv txoj kev, lub thickness ntawm cov av npog rau saum cov yeeb nkab yuav tsum tsis pub tsawg tshaj 0.7 meters. Yog tias koj xav tau hla cov teeb meem, koj yuav tsum tau teeb tsa lub thawv tiv thaiv ua los ntawm cov hlau tuav. Thaum tso lub raj xa dej, nws yuav tsum tau tsim ua ib txoj kab ncaj nraim. Yog tias nws tsim nyog siv qhov hloov pauv hloov pauv rau kev tso nrog cov kab tawg, lub kaum sab xis ntawm txoj kab ntev ntawm txoj kab txuas txuas yuav tsum tsis txhob siab dua 2 degree. Thaum lub faus qhov tob ntawm lub raj xa dej qis dua qhov chaw hauv qab ntawm lub hauv paus ntawm lub tsev, cov kav dej yuav tsum tsis txhob muab tso rau hauv qhov chaw compression ntawm lub hauv paus diffusion lub kaum sab xis hauv qab lub hauv paus ntawm lub tsev. Thaum cov dej hauv av siab tshaj qhov siab ntawm qhov trench hauv qab, kev ntsuas kom txo cov dej hauv av yuav tsum tau ua thaum tsim kho kom tsis txhob muaj qhov trench tsis ruaj khov. khov.
(2) Raws li qhov siab ntawm qhov chaw sab nraud, PE kav nrog qhov sib txawv nruj yuav tsum tau xaiv.
(3) Thaum nqa tawm trench excavation, qhov dav ntawm qhov zawj hauv qab ntawm PE yeeb nkab trench yuav tsum tau txiav txim siab ua ntej, raws li cov kev cai tsim kho, txhawm rau pab txhawb kev ua haujlwm ntawm phau ntawv. Thaum lub sij hawm kev tsim kho, tsis pub dhau-digging ntawm trenches. Yog tias kev khawb ntau dhau yog ua tsis tiav, nws raug nquahu kom siv cov xuab zeb thiab gravel rau kev pov tseg. Qhov luaj li cas ntawm cov xuab zeb thiab pob zeb rau kev pov tseg yuav tsum nyob nruab nrab ntawm 10mm thiab 15mm, los yog qhov siab tshaj particle loj yuav tsum tsawg dua 40mm.
(4) Lub hauv paus kav dej tau txais cov xuab zeb cushion foundation, thiab cov grooves yuav tsum tau tshwj tseg ntawm qhov sib cuam tshuam los pab txhawb kev ua haujlwm ntawm kev sib tshuam. Tom qab kev tsim kho ntawm lub interface tiav, nws yuav tsum tau sau nrog xuab zeb. Rau cov av dav dav, tsuas yog ib txheej ntawm cov xuab zeb cushion nrog lub thickness ntawm 0.1M yuav tsum tau muab tso rau. Yog tias nws yog lub hauv paus av mos thiab hauv qab ntawm qhov zawj yog hauv qab lub rooj dej hauv av, ib txheej ntawm cov xuab zeb thiab pob zeb hauv av nrog lub thickness ntawm tsis pub tsawg tshaj 500px yuav tsum tau muab tso rau.
(5) Thaum lub sijhawm teeb tsa thiab kev tsim kho ntawm cov yeeb nkab hauv qab, qhov zawj dav, qhov tob tob, qhov siab ntawm lub hauv paus, kev tshuaj xyuas zoo, thiab lwm yam. kauj ruam tom ntej. , txhawm rau txhim kho kev tsim kho kom zoo.
(6) Tom qab kev tshuaj xyuas tiav, cov kauj ruam tom ntej yog txuas thiab nruab PE yeeb nkab. Cov txheej txheem kev teeb tsa ntawm phau ntawv yuav tsum tau siv rau cov hlua uas tsis yog xim hlau zawv zawg, kom cov kav dej tuaj yeem muab tso rau ntawm lub hauv paus gravel stably. Qhov kev txiav txim ntawm lub qhov (socket) thiab lub qhov (socket) yeeb nkab feem ntau yuav tsum yog nyob rau hauv cov kev taw qhia ntawm cov dej ntws ntawm lub qhov (socket) thiab cov kev taw qhia ntawm cov dej ntws ntawm lub qhov (socket), thiab qhov kev txiav txim ntawm installation los ntawm qis mus rau siab yuav tsum tau nqa tawm. Thaum cov txheej txheem interface yog ua tiav, ua ntej ntxuav cov chaw nres nkoj ntawm ob sab thiab tom qab ntawd siv cov roj lubricating. Tom qab tha xim, kho cov kab hauv nruab nrab thiab tos kom sib txuas. Kev sib txuas ntawm cov raj xa dej thiab cov tshuaj ntsuam xyuas zoo tuaj yeem txuas nrog cov txheej txheem nruab nrab. Cov kav dej hauv qhov sib txuas ntawm ob yog ua ntej ua nrog cov nplaum yas thiab cov xuab zeb ntxhib uas tuaj yeem txuas tau zoo rau cov yeeb nkab ua cov txheej txheem nruab nrab, thiab tom qab ntawd txuas nrog 1: 2.5 cement. Lub cug tshuaj yog ua rau hauv phab ntsa zoo kom ua rau qhov sib txuas ntawm cov yeeb nkab yog qhov yooj yim, thiab cov yeeb nkab sab hauv cov yeeb nkab yog yaug nrog sab hauv phab ntsa ntawm lub qhov dej.
(7) Tom qab cov kav dej PE raug teeb tsa, nws yuav tsum tau soj ntsuam nruj me ntsis. Yog tias qhov kev tshuaj xyuas tsim nyog, qhov trench backfilling yuav pib. Thaum lub trench rov qab, qhov ntau ntawm hauv qab ntawm cov yeeb nkab mus rau sab saum toj ntawm cov yeeb nkab hauv 1750px yuav tsum tau manually backfilled, thiab cov khoom siv rov qab siv tau tsuas yog siv yog tias nws ntau dua 1750px. . Thaum backfilling, xyuas kom meej tias tsis muaj cov khib nyiab hauv lub trench. Tsis tas li ntawd, lub compaction degree ntawm backfilling yuav tsum tsis txhob tsawg tshaj li 95 feem pua rau lub thoracic kab noj hniav, tsis tsawg tshaj li 80 feem pua rau sab saum toj 500 hli ntawm lub raj, thiab tsis tsawg tshaj li 90 feem pua rau lwm qhov chaw. Kev saib xyuas kuj yuav tsum tau them nyiaj rau kev xaiv cov khoom siv compaction kom tsis txhob muaj kev puas tsuaj rau lub raj xa dej thaum tsim kho.
