CFG (Cement Fly ash Grave) mulu, womwe umadziwikanso kuti simenti fly ash phulusa mulu mu Chitchaina, ndi mulu wolumikizana kwambiri wopangidwa ndi simenti yosakanikirana, phulusa la ntchentche, miyala, tchipisi ta miyala kapena mchenga ndi madzi mosakanikirana. Zimapanga maziko ophatikizika pamodzi ndi dothi pakati pa milu ndi khushoni wosanjikiza. Ikhoza kugwiritsira ntchito mphamvu za zinthu za mulu, kugwiritsira ntchito mphamvu zonyamulira za maziko achilengedwe, ndi kusintha zipangizo zam'deralo malinga ndi momwe zilili m'deralo. Zili ndi ubwino wochita bwino kwambiri, zotsika mtengo, zowonongeka pomanga positi, komanso kukhazikika kwachangu. CFG mulu maziko mankhwala tichipeza angapo: CFG mulu thupi, mulu kapu (mbale), ndi wosanjikiza khushoni. Mtundu wamapangidwe: mulu + slab, mulu+kapu+tsamira wosanjikiza (mawonekedwe awa atengedwa m'chigawo chino)
1,CFG mulu kumanga luso
1. Kusankhidwa kwa zida ndi kuyika milu ya CFG kutha kuchitidwa pogwiritsa ntchito makina obowola a vibration omizidwa kapena makina obowola atali ozungulira. Mtundu weniweni ndi mtundu wa makina opangira milu omwe angagwiritsidwe ntchito zimadalira momwe polojekiti ikuyendera. Pa dothi lolumikizana, dothi la silt, ndi dothi la silt, njira yopangira milu ya chubu yogwedera imatengedwa. Kwa madera omwe ali ndi zigawo za nthaka yolimba, kugwiritsa ntchito makina ogwedera omangika pomanga kumapangitsa kugwedezeka kwakukulu kwa milu yomwe yapangidwa kale, zomwe zimapangitsa kuti muluwo uphwanyike kapena kuthyoka. Kwa dothi lomwe lili ndi mphamvu zambiri, kugwedezeka kungayambitse kuwonongeka kwa mphamvu ndi kuchepa kwa mphamvu yobereka. Kubowola kozungulira kumatha kugwiritsidwa ntchito pobowola kale, kenako chubu lomira la vibration litha kugwiritsidwa ntchito kupanga milu. Kumadera kumene kubowola kwapamwamba kumafunika, chitoliro chautali chozungulira chimagwiritsidwa ntchito kupopera ndi kupanga milu. Gawoli lapangidwa kuti lipangidwe pogwiritsa ntchito chobowolera chozungulira chachitali. Palinso mitundu iwiri ya makina omangira opopera konkire mkati mwa mapaipi obowola ozungulira: mtundu woyenda ndi mtundu wa crawler. Makina obowola amtundu wa Crawler ali ndi makina obowola amtundu wautali. Malingana ndi ndondomeko ndi mayesero a ndondomeko, kasinthidwe ka zidazo kumayendetsedwa ndikusungidwa panthawi yake kuti makina onse azikhala bwino, akwaniritse zofunikira zomanga, komanso kuti asasokoneze kupita patsogolo ndi khalidwe la zomangamanga.
2. Kusankhidwa kwa zipangizo ndi kusakaniza kusakaniza kwa zipangizo monga simenti, phulusa la ntchentche, mwala wophwanyidwa, ndi zowonjezera ziyenera kukwaniritsa zofunikira ndi zofunikira zokhudzana ndi kuvomereza kwabwino kwa zopangira, ndikuwunika mwachisawawa malinga ndi malamulo. Chitani mayeso osakanikirana amkati molingana ndi kapangidwe kake ndikusankha milingo yoyenera yosakanikirana.
2,Njira zoyendetsera bwino za milu ya CFG
1. Tsatirani mosamalitsa chiŵerengero chosakanikirana cha mapangidwe panthawi yomanga, mwachisawawa sankhani gulu la zitsanzo za konkire kuchokera pazitsulo zonse zobowola ndi kusuntha, ndipo gwiritsani ntchito mphamvu zopondereza monga muyezo wodziwira mphamvu ya kusakaniza;
2. Chingwe chobowola chikalowa pamalowo, choyamba gwiritsani ntchito chowongolera chachitsulo kuti muwone kukula kwa ndodo yobowola. Kutalika kwa ndodo yobowola sikuyenera kukhala yocheperako kuposa mulu wa mulu wa mapangidwe, ndipo kutalika kwa nsanja yayikulu yobowola kuyenera kukhala pafupifupi mita 5 kuposa kutalika kwa mulu;
3. Musanabowole, masulani malo owongolera ndikupereka chidziwitso chaukadaulo kwa ogwira ntchito pobowola. Ogwira ntchito pobowola adzagwiritsa ntchito chitsulo chowongolera kuti amasule mulu uliwonse potengera milu yolamulira.
4. Musanayambe kubowola, pangani zizindikiro zomveka bwino pa nsanja yaikulu ya chobowoleracho potengera kutalika kwa mulu wopangidwa ndi makulidwe a mutu wa mulu wotetezera wosanjikiza, monga maziko owongolera kuya kwa kubowola.
5. Pambuyo pobowola m'malo mwake, mkuluyo amalamula chobowolacho kuti chisinthe malo ake, ndipo amagwiritsa ntchito zizindikiro ziwiri zoyima zomwe zikupachikidwa pa chimango kuti adziwe ngati verticality ya chobowola ikukwaniritsa zofunikira;
6. Kumayambiriro kwa CFG mulu yomanga, pali nkhawa kuti mulu ndi mulu yomanga zingachititse mtanda dzenje kubowola. Chifukwa chake, njira yomanga yolumikizira milu yapakati imagwiritsidwa ntchito. Komabe, ngati kulumpha kwapanthawi kochepa kumagwiritsidwa ntchito, chiphaso chachiwiri choyendetsa milu m'malo mwake chingayambitse kupanikizana ndi kuwonongeka kwa milu yomwe yamangidwa kale. Chifukwa chake, kudumpha ndikuwunjika ndikuyendetsa mulu kuyenera kusankhidwa motengera momwe zinthu zilili.
7. Mukathira konkire mu milu ya CFG, kupanikizika pamwamba pa mamita 1-3 a konkire kumachepa, ndipo ming'oma yabwino mu konkire sangathe kumasulidwa. Waukulu katundu onyamula mbali ya CFG milu ali kumtunda, kotero kupanda compactness chapamwamba mulu thupi mosavuta kuwononga mulu pa ntchito zomangamanga. Njira yothetsera vutoli ndiyo kugwiritsa ntchito ndodo yogwedezeka kuti igwirizane ndi konkire yapamwamba pambuyo pomanga ndipo isanayambe kulimba, pofuna kulimbikitsa kugwirizanitsa kwa konkire; Chachiwiri ndi kulimbikitsa ulamuliro wa konkire kugwa, monga kugwa yaing'ono mosavuta chifukwa zisa chodabwitsa.
8. Kuwongolera kwa chitoliro chokoka chitoliro: Ngati chitoliro chokoka chitoliro chiri chothamanga kwambiri, chimapangitsa kuti muluwo ukhale wochepa kwambiri kapena kuti muluwo utsike ndi kusweka, pamene kukoka chitoliro kukuchedwa kwambiri, kungayambitse kusagwirizana. kugawa matope a simenti, matope oyandama oyandama pamwamba pa mulu, mphamvu yosakwanira ya mulu wa muluwo, komanso mapangidwe a tsankho losakanikirana, zomwe zimapangitsa kuti muluwo ukhale wosakwanira mphamvu. thupi. Chifukwa chake, pakumanga, kuthamanga kokoka kuyenera kuyendetsedwa mosamalitsa. Kuthamanga kukoka nthawi zambiri kumayendetsedwa pa 2-2.5m / min, yomwe ili yoyenera kwambiri. Liwiro lokoka apa ndi liwiro la mzere, osati liwiro lapakati. Ngati mukumana ndi dothi la silt kapena silt, liwiro lokoka liyenera kuchepetsedwa moyenera. Kulowetsa m'mbuyo sikuloledwa panthawi yochotsa.
9. The kusanthula ndi kuchiza mulu breakage amatanthauza discontinuity wa konkire pamwamba pa CFG mulu pambuyo aumbike, ndi ming'alu kapena mipata perpendicular chapakati olamulira mulu pakati. Kusweka kwa mulu ndiye ngozi yayikulu kwambiri ya milu ya CFG. Pali zifukwa zambiri za kusweka kwa mulu, makamaka kuphatikizapo: 1) chitetezo chokwanira chomanga, makina akuluakulu omanga omwe amagwira ntchito m'madera a CFG omwe ali ndi mphamvu zosakwanira, zomwe zimapangitsa kuti muluwo uphwanyidwe kapena mutu wa mulu uphwanyidwe; 2) Valavu yotulutsa mpweya wautali wautali watsekedwa; 3) Mukathira konkire, kutsanulira konkriti sikuyenera nthawi yake; 4) Zifukwa za nthaka, madzi ambiri apansi panthaka, komanso kupezeka mosavuta kwa milu yosweka; 5) Kusagwirizana kosagwirizana pakati pa kukoka chitoliro ndi kupopera konkire; 6) Kugwira ntchito molakwika panthawi yochotsa mutu wa mulu kunayambitsa kuwonongeka.
