Kunzwisisa zvakanakira ASTM A139 Spiral Steel pombi yePasi pevhu Gasi Pipi Plapes
Suma:
Kana zvasvika kune zvakasikwa gasi rekufambisa, kukosha kwepasi pevhu mapendekero ekupfeka hazvigone kuve kwakaringana. Iyi pombi dzinovimbisa kutumirwa kwakachengeteka uye kushanda kwesimba iri rinokosha kune dzimba, mabhizinesi uye indasitiri. Kuve nechokwadi chekuti hupenyu hwakareba, kuvimbika uye kusimba kweiyi mapaipi, kushandiswa kwezvinhu zvepamusoro-zvemhando yepamusoro. Pakati pezvakawanda zvisarudzo zviripo,ASTM A139Spiral Steel pombi inomira sesarudzo yakakosha. Mune ino blog, isu tichapinza mune izvo zvimiro uye zvakanaka izvo zvinoitaASTM A139Izvo zvinyorwa zvekusarudzwa kwePasi pevhu zvakasikwa gasi gasi pipi.

Hydrostatic test
Kureba kwepepe kuchaidzwa nemugadziri kune hydrostatic kumanikidza kuchagadzira madziro kushushikana kwekushaiwa makumi matanhatu muzana yeiyo yakasarudzika shuwa simba rekubereka tembiricha. Dzvinyiriro ichatsanangurwa neiyo inotevera equation:
P = 2st / d
Zvinotenderwa kusiyana kwehuremu uye zviyero
Kureba kwega kwega kwembwa kucharemerwa zvakasiyana uye kurema kwayo hakuzopindirane kupfuura gumi muzana pamusoro kana 5.5% pasi pehuremu hwayo uye huremu hwayo uye huremu hwayo pahurefu.
Iyo yekunze dhisiki haizosiyane kupfuura ± 1% kubva pane yakatarwa zita rekunze kunze kwedhimoni.
Kukudza kwemadziro chero nguva hakusi kupfuura gumi nemairi% pasi peiyo yakataurwa madziro.
Kureba
Hurefu hwakasarudzika: 16 kusvika 25ft (4.88 kusvika 7.62m)
Kaviri akareba kureba: Pamusoro pe25ft kusvika ku15ft (7.62 kusvika 10.67m)
Yunifomu Yakareba: Inotenderwa Kusiyana ± 1in
Magumo
Pipe Piles ichagadzirwa nebani magumo, uye burrs kumahombekombe
Kana iyo pombi yekupedzisira yakatsanangurwa kuve yechiodzwa magumo, iyo angle ichave nemakumi matatu kusvika ku35 degree
ASTM A139: Kusarudzwa kwePasi pevhu zvakasikwa gasi pombimitsara:
1. Simba uye kusimba:
ASTM A139Spiral Steel pombiinozivikanwa nekuda kweiyo yakanaka kwazvo uye kukanganisa simba. Hunhu uhwu hwakakosha pasi pevhu repasi pevhu rakasarudzika gasi peilline nekuti vanogara vachivhenekwa zvakasiyana siyana zvemamiriro ekunze uye pasi pevhu. Kugadzirwa kwekunyepedzera kwembambo yesimbi kunowedzera kutendeka kwayo, kuchibvumira kuti itambe nekukwirisa kwekunze kwekunze uye kuderedza njodzi yekukora kana kupururudza.
2. Corrosion Rishance:
Pipisi yepurasitire inokanganiswa neCorrosion inokonzerwa nemvura, ivhu rechikadzi uye zvimwe zvinhu. ASTM A139 Spiral Steel pombi inogadzirisa dambudziko iri nekupa simba repamusoro kupesana. Izvi zvinonyanya kukonzerwa neye zinc-yakapfuma-muchivimbiso chekudzivirira, chinoita kuti hurefu hwenyepi uye kuderedza kudiwa kwekugara kana kutsiva.
3. Waldability uye Kuedza:
ASTM A139 Spiral Steel pombi ine Weldy Weldy, kubvumira kuti ive yakasimba, inoshanda majoini panguva yekuisirwa. Ichi chimiro chinonyanya kubatsiraPasi pevhu zvakasikwa gasi pombi, Sezvinoita kuti kuvimbika kwe pombi ye pombi uye kuderedza njodzi yekudonha. Pamusoro pezvo, kuwedzera kwetsiva simbi inozvitendera kuti iite nyore kugadzirwa mumatanho akasiyana uye madhiri ekusangana nezvinodiwa zvakasiyana, nekudaro kubatsira mukubudirira uye kugadziriswa.
4. Kubata-kushanda:
Chimwe chinhu chakakosha chekushandisa ASTM A139 Spiral Steel pombi yePasi pevhu gasi zvakasikwa gasi peilline mari yayo mutengo. Iko kusimba kwezvinhu, kupokana uye kureruka kwekuisa kuendesa kuendesa kwenguva refu uye kutsiva mutengo. Pamusoro pezvo, iyo yakakwira simba-yehuremu ratio inoderedza kudiwa kwechimiro chakatsigirwa panguva yekuisirwa, zvichikonzerwa nemutengo wakawanda mari.
5. Kufungisisa kwekutsigira:
ASTM A139 Spiral Steel pombi inogadzirwa uchishandisa nharaunda inoshamwaridzana maitiro uye inonamatira kune yakanyanya kuchengetedza zviyero. Zvivakwa zvaro zveCorrosion zvinobatsira zvinobatsira kudzivirira gasi kubhururuka, pakupedzisira kuderedza zvakaratidzwa zvemamiriro ekunze. Pamusoro pezvo, kusanzwisisika kwesimbi kunoita kuti isimbe yemamiriro ezvinhu epamoyo, kuwedzera kusimbisa mabhenefiti ekushandisa kwekushandisa ASTM A139 Spiral Steel pombi yepasi pepasi pevhu gasi yepasi pepasi pepasi pepasi pepasi pevhu
Mukupedzisa:
Kusarudza zvinhu zvakaringana zvevakadzika pasi pevhu zvakasikwa gasi peilline zvakakomba kuti uve nechokwadi chekufambisa uye chakavimbika uye chakavimbika cheiyi yakakosha simba. ASTM A139 Spiral Steel sarudzo yakanakisa nekuda kwesimba rayo, kusimba, kurwisa, masaga, zvinodhura, zvinodhura, uye nekufunga kwezvakatipoteredza, uye nekufunga kwezvakatipoteredza, uye nekufunga kwezvakatipoteredza, uye nekufunga kwezvakatipoteredza, uye nekufunga kwezvakatipoteredza, uye nekufunga kwezvakatipoteredza, uye nekufunga kwezvakatipoteredza, uye nekufunga kwezvakatipoteredza. Zvivakwa zvaro zvakasarudzika zvinoita sarudzo yekutanga yeinjiniya uye mamaneja eprojekita anotarisa kuvaka pasi pevhu yepasi pepasi pemasirese iyo ichamira muyedzo wenguva. Nekudyara mune zvemhando yepamusoro seastm a139 Spiral Steel pombi, isu tinogona kuve nechokwadi chekuchengetedza uye chakachengeteka gasi rekuparadzira nzvimbo dzekuparadzira zvizvarwa zvinotsauka zvizvarwa zvinouya.
