Chophimba cha maneyule chimakhala chophimba chimakhala chophimba cha manhole, ndipo mawonekedwe ake amafotokozedwa: Chophimba cha Manhole chimaphatikizidwa ndi njira inayake pogwiritsa ntchito polymer, etferc, etfer.
M'malo mwake, onetsani chivundikiro cha manhole (chotchedwanso polymer galasi chivundikiro chofiyira / chophimba cha Manhole chimagwiritsa ntchito chivundikiro cha galasi chomwe chimagwiritsa ntchito, nthiti) ngati matrix. Zimakhala ndi zowonjezera zolembedwa, ma vferesenti, omaliza, owonjezera owonjezera owonjezera, makanema olimbikitsa, kenako ndi mtundu watsopano wa chivundikiro chabwino.
Zina mwa zida zowonjezerapo, zida zolimbikitsira zitsamba (nsalu zamagalasi, zimamveka, ulusi, etc.) ndizodziwika bwino, mphamvu zazikulu komanso zopanda ulemu mwachindunji. Mwachitsanzo, zophatikizika za kaboni kumera ndi epoxy zotukula, mphamvu zake zina komanso zotupa, komanso kusokonekera kwa mankhwala, kutopa kokhazikika, kusokonezeka kwa maphokoso komanso zinthu zina. Wophatikizira wa graphite fiber ndi restin amatha kupeza zinthu ndi zowonjezera zokulira pafupi ndi zero. Chimodzi china cha zinthu zolimbika zitsamba ndi anisotropy, kotero makonzedwe a ulusi angapangidwire malinga ndi zofunikira za magawo osiyanasiyana a mankhwalawo. Alumuniyam matrix amapanga zolimbikitsira ndi kaboni ndipo ulusi wa carbide wa carbide akhoza kukhalabe wolimba mphamvu komanso modulus pa 500 ° C.
Zovala zophatikizira manhole zitha kugawidwa mu BMC ndi SMC malinga ndi msika wogulitsa, njira zosiyanasiyana zokhala ndi zida:
BMC (DMC) zida ndi mankhwala owumba ambiri. Nthawi zambiri zimatchedwa polysite zochulukirapo poldereng ku China ku China. Zolemba zazikuluzikulu ndi zopaka zokhala ndi mtanda zomwe zimasakanizidwa kwathunthu ndi gf (fibeshi yagalasi), kwezani (osavomerezeka), MD (zowonjezera) ndi zowonjezera) ndi zowonjezera zosiyanasiyana. Zipangizo za DMC idagwiritsidwa ntchito koyamba ku Germany yatha ku Germany ndi United Kingdom m'ma 1960s, kenako adayamba ku United States ndi Japan ndipo m'ma 1970s, motsatana. Chifukwa BMC youmba youmba imakhala ndi katundu wamagetsi, makina opanga, kugwiritsa ntchito mankhwala osokoneza bongo, ndikugwiritsidwa ntchito kwambiri pamayendedwe osiyanasiyana, zowonjezera zamagetsi, zamagetsi ndi minda ina.
Mitundu ya SMC imapanga mapepala opanga mateke. Zida zazikuluzikulu zimapangidwa ndi gf (ulusi wapadera), mmwamba (osavomerezeka), owonjezera owonjezera, owonjezera owonjezera, MD (Final) ndi opanga) ndi opanga. Chimawonekera koyamba ku Europe kumayambiriro kwa m'ma 1960s, ndipo pafupifupi 1965, United States ndi Japan inayamba kupanga nsanguyi. Chakumapeto kwa zaka za m'ma 1980, dziko langa linadziwitsa mizere yakunja ya SMC ndi njira. Zida za SMC zimaphatikizika ndi zinthu zawo za SMC zimakhala ndi katundu wamagetsi wabwino kwambiri, makina opanga, kukhazikika kwamafuta, ndi mankhwala osokoneza bongo. Chifukwa chake, ntchito zosiyanasiyana za SMC zimafala kwambiri. Zochita zaposachedwa ndikusintha zida za BMC zomwe zimapanga ma stc.
Tsopano kugwiritsa ntchito zitsulo zathu kumapangitsa kuti pakhale gawo lalikulu m'moyo wathu, ndipo ma vehole amalima manhole amawoneka chifukwa cha ntchito yawo yoyeretsa.
Kugwiritsa ntchito manhole manhole pamsewu kuli ndi mawonekedwe a makutu, palibe phokoso, palibe njira yachilengedwe ndi kuba kwa antial. Sizingafanane ndi chitsulo champhamvu cha manhole.
Chophimba cha marhole chimapangidwa ndi njira yapadera, yomwe imapangitsa kuti mzindawu ukhale watsopano. Moyo wa Utumiki uli zaka 20-50. Chophimba cha Manhale Manhole chophimba chopangidwa ndi kutentha kwambiri kumaumba kumakhala ndi maubwino a kulemera kopepuka komanso mphamvu yayikulu, kukana kutsuka kochepa komanso chitetezo chowonongeka. Ili ndi maubwino owumbidwa mosavuta, phokoso lopera, kukana kwabwino kwa asidi ndi alkali kukana komanso mawonekedwe okongola, ndipo zodetsa mu madzi otayira zimachepetsedwa.
Tsopano pamsika, zophimba zopangidwa ndi opanga zojambula zophatikizika ndi zida zosiyanasiyana, koma zinthu zingapo ndizofanana:
1. Mankhwala amphamvu a Anti-THFIME Kulimbikitsidwa sikophweka.
2. Moyo wa Utumiki: Kugwiritsa ntchito utoto wambiri, fibri ya kalasi ndi kupanga kwapadera kwa chivundikiro, ndipo zotsatsa pakati pa ziwirizi zimakulitsidwa kwambiri, kuti zinthu zisawonongeke ndi Chovala cha cyclic. Zowonongeka zamkati zimachitika, ndikuwonetsetsa moyo wazogulitsa ndi zomwe zimapangitsa kuti muthetse mavuto omwe amachititsa manyazi.
3. Kutentha kwakukulu / Kulimbana ndi kutentha kwa kutentha, kugwiritsa ntchito bwino magwiridwe antchito komanso kukana kwamphamvu kwa kuchuluka kwa mphukira: Chogulitsacho ndi chopanda mphamvu, osavulaza komanso osavulaza. Palibe zowonjezera zitsulo. Itha kugwiritsidwa ntchito pa zovuta komanso zosinthika, zolimba komanso zowopsa. Zilembo zopangidwa ndi bester zimapangidwa Manhole Pursers opanga ayesedwa ndi mabungwe oyenererana ndi alkali akutsutsa, kutsutsana ndi otsutsa, otsutsa ena.
4. Zokongola komanso zopambana, malinga ndi zosowa za makasitomala apamwamba, titha kupanga logo yosiyanasiyana ndipo timakhala osakhwima, kuti mawonekedwewo ndi owala komanso omveka bwino. Malinga ndi zofunikira za makasitomala, zitha kupangidwa mumiyala yopanda tanthauzo yopanda miyala ndi mitundu yomwe imakhala yofanana ndi mitsempha yosiyanasiyana yamiyala.
5. Mphamvu zamphamvu: pansi zimatengera kapangidwe kake, ndipo chiberekero chokhazikikanso chogwiritsidwa ntchito chimapangidwa ndi zinthu kuti chitsimikizidwe ndi chiberekero cha galasi ndi nsalu zagalasi zimaphatikizidwa, kuti malonda ali ndi mphamvu inayake.
6. Kuteteza zachilengedwe, osakhazikika, phokoso lotsika: chivundikiro cha manhole sichingadutse galimoto ikagudubuzika, ndipo sipadzakhala phokoso la khunyu.
Mukakhazikitsa chivundikiro chophatikizika, tsatirani njira zinayi izi:
1. Musanakhazikike, maziko a chivundikiro cha manhole ayenera kukhala oyera komanso olimba, ndipo kutalika kwa m'mimba, kutalika kumayenera kutsimikizika malinga ndi kukula kwa chivundikiro cha manhole.
2. Mukakhazikitsa chivundikiro cha marhole pamsewu wa simenti, samalani ndi chitsime cha chitsime chikuyenera kuthiridwa ndi konkriti, ndipo mphete yoteteza konkriti iyenera kukhazikitsidwa pampando kuti ikonzedwe pafupifupi masiku 10.
3. Mukakhazikitsa manholele ophatikizika pamiyala ya phula la phula, chidwi chiyenera kulipidwa kuti mupewe makina omangawo mwachindunji ndi mpando wabwino kuti musawonongeke.
4. Pofuna kukhalabe kukongola kwa chivundikiro cha manhole ndi zolemba zomveka bwino ndi njira, samalani kuti musamale chivundikiro cha manhule tikamatsanulira phula ndi simenti pamsewu.
Njira Yoyambira:
. Imatha kunyamula magalimoto oposa 40.
. Itha kugwiritsidwa ntchito nthawi zambiri ndi zofunikira zaukadaulo za manhole zophimba.
. Chifukwa chake, ili ndi mwayi wokhala osavomerezeka pamene mtengo wa zitsulo zikupitirirabe. Chifukwa mulibe chitsulo chaching'ono, chimangoletsa mabati-kuopsa kuposa pulasitiki ndi ulusi manhole amaphimba.
. Ngati imapangidwa m'masitepe atatu, imatha kuipitsidwa katatu mu maola 24. Ngakhale kuchuluka kwa nkhungu ndi kochulukirapo kuposa pulasitiki yamiyala, ndi 1/6 yokha ya chivundikiro cha maryter marhole. Zingachepetsenso kuchuluka kwa nkhungu. Ndi kutulutsa kwapachaka kwa matope 10,000, mapangidwe 10 okha a mafupa amafunikira.
