Paipa u'amea ta'amilo mo le sapalai o vai ma alavai

Faamatalaga oloa

O paipa ta'avale o lo'o fa'aaogaina i le taulaga vai ma alavai e masani lava ona fa'asino i paipa uelo, o se ituaiga masani o paipa u'amea o lo'o fa'aaogaina lautele i le taulaga vai ma alavai galuega. O paipa u'elo fa'apipi'i ua fa'aigoaina mo o latou su'iga fa'asolosolo tulaga ese. O le ituaiga paipa lea e gaosia e fa'aoga ai le faiga o le li'o e fa'apipi'i ai fasi u'amea po'o papatusi i se foliga fa'ata'oto ma fa'afeso'ota'i su'iga e ala i le uelo.

O paipa ta'avale o lo'o fa'aaogaina i le taulaga vai ma alavai e masani lava ona fa'asino i paipa uelo, o se ituaiga masani o paipa u'amea o lo'o fa'aaogaina lautele i le taulaga vai ma alavai galuega. O paipa u'elo fa'apipi'i ua fa'aigoaina mo o latou su'iga fa'asolosolo tulaga ese. O le ituaiga paipa lea e gaosia e fa'aoga ai le faiga o le li'o e fa'apipi'i ai fasi u'amea po'o papatusi i se foliga fa'ata'oto ma fa'afeso'ota'i su'iga e ala i le uelo.

O nisi nei o manatu autu e uiga i paipa taamilo mo le sapalai o vai ma alavai i le taulaga:

Fa'agasologa o le gaosiga: O paipa ta'amilomilo e gaosia e ala i se faiga fa'apipi'i, ma o lo'o fa'aulu i le fa'aogaina o le uelo fa'ato'ilalo otometi po'o le uelo maualuga e fai ai se uelo fa'aauau.

Avanoa o le faʻaoga: O paipa faʻapipiʻi e talafeagai mo le felauaiga o vai maualalo e pei o vai, otaota, ea, faʻamafanafanaga, ma isi mea, ma e masani ona faʻaaogaina i le taulaga vai ma alavai galuega.

Manaoga faʻapitoa: O le gaosiga ma le faʻaogaina o paipa taʻavale e tatau ona tausisia tulaga faʻale-atunuu, e pei o le GB / T 3091-2015 "Welded Steel Pipes for Low-Pressure Fluid Transport", ma isi. , ma isi o paipa uamea.

Tekonolosi faufale: Pe a faia le fauina o le si'osi'o fau o paipa la'ititi la'ititi mamao i nofoaga mafiafia i le taulaga, e mafai ona fa'aogaina tekinolosi faufale fa'apitoa, pei ole auger micro-pipe jacking technology. O lenei tekinolosi o lo'o i ai le lelei o le maualuga o le sa'o lelei o le paipa ma le lelei o le a'afiaga i luga o le eleele lata ane. O mea lelei e aofia ai faʻalavelave laiti.

Fa'atekonolosi fou: I le fa'aogaina o le si'osi'o fau o paipa la'ititi la'ititi mamao i totonu o le taulaga mafiafia, e mafai ona fa'aaogaina nisi o tekonolosi fou, e pei o le mamao ma le maualuga o le fa'atonutonuina o tekonolosi o le auger pipe jacking system guide, mamao mamao. ma le sa'o maualuga tekinolosi pulea o le auger jacking pipe jacking system i oneone ma iliili formations Mamao faaauau pea tekinolosi jacking, grouting toso faaitiitia ma anti-locking tekinolosi fausiaina i vaitaimi vavalo o auger paipa jacking, ma isi, e foia faigata i le fausiaina.

Manaoga faʻamatalaga: Ole ituaiga, faʻamatalaga, ma le faʻatinoga o mea mataʻutia, oloa semi-maʻa, oloa maeʻa ma isi oloa faʻaaogaina i le taulaga vai ma alavai paipa e tatau ona tausisia tulaga talafeagai a le atunuʻu ma manaʻoga mamanu.

Tausiga ma le saogalemu: O galuega faatino o le sapalai o le vai i le taulaga ma alavai e tatau ona mulimulitaʻi ma tulafono faʻapitoa mo le tausiga ma le saogalemu, e pei o le CJJ 58-2009 "Urban Water Supply Plant Operation, Maintenance and Safety Technical Regulations", ma isi, ina ia mautinoa le saogalemu ma le saogalemu. fa'atuatuaina le fa'aogaina o le vai.

Puleaina o le lepa: Mo feso'ota'iga paipa vai i le taulaga, e taua tele fo'i le fa'atonutonuina o le liki. E tatau ona mulimulitaʻi faʻamatalaga e pei o le CJJ 92-2016 "Leakage Control and Assessment Standard for Urban Water Supply Pipeline Networks" e faʻaitiitia ai le faʻaleagaina o punaoa vai.

I le aotelega, i le taimi o le gaosiga, fausiaina, faʻaogaina ma le tausiga o paipa paipa mo le tuʻuina atu o le vai i le taulaga ma alavai, e tatau ona mulimulitaʻia tulaga faʻapitoa a le atunuʻu ma faʻamatalaga ina ia mautinoa le lelei o le poloketi ma le saogalemu ma le lelei o le faʻaogaina o le suavai i le taulaga. ma alavai.
