PE bomba manispaa kuzikwa maji ugavi mpango wa ujenzi: moto kuyeyuka uhusiano na majibu ya makazi

2025-08-18


PE bomba hutumiwa sana katika usambazaji wa maji ya manispaa yaliyozikwa kutokana na upinzani wake wa kutu na kubadilika kwa nguvu. Wakati wa ujenzi, ni muhimu kuzingatia kudhibiti ubora wa muunganisho wa moto kuyeyuka na hatua za makazi ili kuhakikisha uendeshaji thabiti wa muda mrefu wa mfumo wa usambazaji wa maji.

muunganisho wa moto kuyeyuka ni mchakato wa msingi wa muunganisho wa bomba la PE, na ni muhimu kufuata kwa ukali vipimo vya operesheni. Kabla ya ujenzi, kuonekana kwa bomba inapaswa kuangaliwa ili kuhakikisha kuwa hakuna mikwaruzo, mifadhaiko, na bandari ni gorofa. Wakati wa kutumia maalum moto kuyeyuka welder, joto joto (kawaida 19010 ° C) na wakati joto inapaswa kuwekwa kulingana na vipimo bomba kipenyo. Baada ya sahani joto inaonyesha hali sare kuyeyuka, haraka kuunganisha bomba na kudumisha shinikizo maalum hadi interface baridi na solidifies. Baada ya muunganisho kukamilika, ni muhimu kuangalia kama kiolesura kimeunda flanging sare, hakuna kulehemu pepe, hali ya kulehemu kuvuja, na kufanya jaribio la shinikizo ikiwa ni lazima. Shinikizo la mtihani sio chini ya mara 1.5 ya shinikizo la kufanya kazi, na shinikizo linaloshikilia kwa dakika 30 bila kushuka kwa shinikizo limehitimu.

Kwa matatizo ya kawaida ya makazi ya msingi katika ujenzi wa manispaa, hatua za kuzuia na kudhibiti zinahitaji kuchukuliwa kutoka kwa viungo vingi vya muundo na ujenzi. Kabla ya kuweka bomba, uchunguzi wa kijiolojia unapaswa kufanywa, na safu laini ya udongo inapaswa kutibiwa na mchanga uliowekwa daraja na uingizwaji wa changarawe, na digrii ya compaction inapaswa kuwekwa kwa 90%. Wakati backfilling, udongo wazi au mchanga na ukubwa wa chembe ya 50mm inapaswa kuchaguliwa, na layered backfill urefu haipaswi kuzidi 300mm. Mwanga roller inapaswa kutumika kwa ajili ya compaction ili kuepuka moja kwa moja mitambo rolling ya bomba. Kwa kuvuka sehemu za barabara au maeneo ya kijiolojia tata, "madaraja bomba" inaweza kuwekwa au fidia bellows inaweza kuanzishwa ili kukabiliana na mafadhaiko ya makazi kwa kutumia kubadilika kwa bomba la PE yenyewe.

mchakato wa ujenzi pia unahitaji kulipa kipaumbele kwa marekebisho ya mazingira. Wakati wa ujenzi wa majira ya baridi, bomba inapaswa preheated kwa zaidi ya 5 ° C kabla ya uhusiano wa moto kuyeyuka ili kuepuka kupasuka kwa joto la chini; wakati wa joto la juu katika majira ya joto, hatua za kivuli zinapaswa kuchukuliwa ili kuzuia bomba kutoka upanuzi wa joto na deformation. Wakati huo huo, kufanya kumbukumbu za ujenzi, ikiwa ni pamoja na vigezo vya kuyeyuka moto, data ya matibabu ya msingi, matokeo ya uchunguzi wa makazi, nk, ili kuunda faili kamili ya kiufundi ili kutoa msingi wa operesheni na matengenezo ya baadaye. Kupitia matumizi ya kisayansi ya teknolojia ya uunganisho wa kuyeyuka moto na teknolojia ya kuzuia na kudhibiti makazi, usalama na uimara wa mfumo wa usambazaji wa maji wa bomba la PE unaweza kuboreshwa kwa ufanisi ili kukidhi mahitaji ya uendeshaji wa muda mrefu wa uhandisi wa manispaa.
