Kusankha kwazinthu zamagalasi owonjezera pansi pamadzi ndi njira zomangira

Kulimbitsa m'madzi apansi pamadzi kumagwira ntchito yofunika kwambiri pazainjiniya zam'madzi komanso kukonza zida zamatawuni. Manja a ulusi wagalasi, epoxy grout pansi pamadzi ndi epoxy sealant, monga zida zofunikira pakulimbitsa pansi pamadzi, ali ndi mawonekedwe okana dzimbiri, mphamvu yayikulu komanso moyo wautali wautumiki, ndipo amagwiritsidwa ntchito kwambiri muzochita zauinjiniya. Pepalali lifotokoza za zidazi, mfundo zosankhidwa ndi njira zomangira zofananira.

I. Glass Fiber Sleeve

Sleeve ya Glass fiber ndi mtundu wazinthu zomwe zimagwiritsidwa ntchito polimbitsa pansi pamadzi, ndipo zigawo zake zazikulu ndigalasi fiberndiutomoni. Ili ndi kukana kwambiri kwa dzimbiri, mphamvu yayikulu komanso kusinthasintha kwabwino, komwe kumatha kukulitsa mphamvu yakubereka komanso magwiridwe antchito a chivomezi. Posankha manja a fiberglass, zinthu zotsatirazi ziyenera kuganiziridwa:
1.Kulimba ndi kuuma: Sankhani mphamvu yoyenera ndi msinkhu wouma molingana ndi zofunikira zenizeni zaumisiri.
2.Diameter ndi kutalika: Dziwani m'mimba mwake yoyenera ndi kutalika kwa manja molingana ndi kukula kwa kamangidwe koyenera kulimbitsa.
3.kukana kwa corrosion: onetsetsani kuti manja a fiberglass amatha kupirira mankhwala omwe ali pansi pa madzi komanso kukokoloka kwa madzi a m'nyanja.

II. pansi pamadzi epoxy grout

Pansi pamadzi epoxy grout ndi chinthu chapadera chopangira ma grouting, chopangidwa makamaka ndiepoxy utomonindi chowumitsa. Lili ndi izi:
1.water resistance: imakhala ndi madzi abwino kwambiri ndipo sichikhudzidwa ndi malo apansi pa madzi.
2.bonding: amatha kupanga mgwirizano wolimba ndi manja a fiberglass ndikuwongolera mphamvu zonse za dongosololi.
3.low viscosity: ndi kukhuthala kochepa, n'kosavuta kutsanulira ndi kudzaza njira yomanga pansi pa madzi.

III. Epoxy sealant

Epoxy sealant imagwiritsidwa ntchito kusindikiza manja a fiberglass mu projekiti yolimbitsa pansi pamadzi, yomwe ingalepheretse kulowa kwamadzi ndi dzimbiri. Makhalidwe ake ndi awa:
1.kukana madzi: kukana madzi abwino, kugwiritsa ntchito madzi kwa nthawi yayitali sikungalephereke.
2.bonding: ikhoza kupanga mgwirizano wapafupi ndi manja a galasi fiber ndi pansi pa madzi epoxy grout kuti apititse patsogolo kukhulupirika kwa dongosolo la polojekiti.

Njira yomanga:

1.Kukonzekera: Yeretsani pamwamba pazitsulo zokhazikika, onetsetsani kuti pamwamba pake mulibe zinyalala ndi zowonongeka.
2.Kuyika kwa manja a fiberglass: konzani malaya a fiberglass pamapangidwe olimbikitsidwa malinga ndi zofunikira za mapangidwe.
3. Dzazani pansi pamadzi epoxy grout: gwiritsani ntchito zida zoyenera kuti mulowetse pansi pamadzi epoxy grout mu manja a fiberglass, ndikudzaza danga lonse la manja.
4.kusindikiza chithandizo: gwiritsani ntchito epoxy sealer kuti musindikize mbali zonse za manja a fiberglass kuti musalowemo chinyezi.

Pomaliza:

Manja a fiber glass, epoxy grout pansi pamadzi ndi epoxy sealant ndi zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri pantchito zolimbitsa pansi pamadzi. Amakhala ndi gawo lofunikira pakunyamula mphamvu, magwiridwe antchito a seismic komanso kulimba kwa zida zolimbikitsidwa. Mwachizoloŵezi, zipangizo zoyenera ziyenera kusankhidwa malinga ndi zofunikira za polojekitiyi ndikugwiritsidwa ntchito molingana ndi njira zomangira zofanana kuti zitsimikizire kuti ntchitoyo ndi yodalirika komanso yodalirika.
