4 DMP-I kikohoʻe micro-disturbance hui puʻu mīkini ukali kokoke
Paena o ka Hui Hoʻonaʻauao Pit Foundation o Pudong Airport Phase IV Expansion Project
ʻOi aku ma mua o 100 poʻe e nānā ana i ka hui "nonlooker"
SEMW TRD, keʻano DMP
Ma ka papahana lua hohonu hohonu loa ma Kina
Ma Mei 10, 2023, ua mālama nui ʻia ka "TAD/DMP Technology Exchange and Observation Activity of Pudong Airport Phase IV Expansion Project" ma ke kahua o Pudong International Airport Phase IV Expansion Project.
Ua mālama ʻia kēia hālāwai nānā a me ka hoʻololi ʻana e ka Rock and Soil Mechanics Professional Committee o ka Shanghai Mechanics Society, Huajian Group Shanghai Underground Space and Engineering Design Research Institute, Shanghai Machinery Construction Group Co., Ltd., Shanghai Yuanfeng Underground Engineering Technology Co., Ltd., a me Shanghai Engineering Machinery Co., Ltd. i komo i ka hui hui. ʻOi aku ma mua o 100 poʻe mai ka noiʻi a me ka hoʻolālā, ke kūkulu ʻana, nā keʻena noiʻi ʻepekema, nā kulanui, nā ʻenehana ʻenehana kūkulu hale a me nā ʻāpana ʻē aʻe i hōʻuluʻulu ʻia a puni nā ʻenehana hou ʻelua o ke ʻano hana hana TAD prefabricated enclosure structure a me DMP construction method digital micro-disturbance mixing pile, mai ka hoʻolālā. ʻO ke kūkulu ʻana a me nā ʻano ʻē aʻe o ka hoʻololi ʻenehana, nā kūkākūkā a me ka nānā ʻana i ke kūkulu ʻana i nā ʻano hana kūkulu hou.
ʻO ka papahana lua hohonu hohonu loa ma Kina
ʻO ka huina o ka lua kumu o ka papahana hoʻonui Phase IV o Pudong International Airport ma kahi o 340,000 m2, ʻo ka hohonu o ka ʻeli ʻana ma kahi o 18.6-30.7 m, a ʻo ka hohonu o ka ʻeli ʻana ma kahi o 36.7 m. ʻO ia ka papahana lua hohonu hohonu loa i kēia manawa ma Kina. A puni ka lua kumu, aia nā mea palekana e like me ka wahi mālama, ke kikowaena ikehu, a me ka laina MRT airside. I ka manawa like, aia nā aquifers i hoʻopaʻa ʻia i hoʻopaʻa ʻia i ka pae hohonu o ka pūnaewele, a ʻo ka nui o ka hāʻule o ka wai paʻa i ka wā o ka ʻeli ʻana a hiki i 30m. He paʻakikī ka ʻenekinia lua kumu, a paʻakikī ka hoʻololi ʻana a me ka hoʻokele wai paʻa.
I loko o ka papahana lua kumu, ua hoʻohana ʻia ka pā diaphragm ma lalo o ka honua me ka hohonu hohonu a me ka like-ka mānoanoa o ke ʻano hana ʻana o ka pā paʻa hui ʻana i ka lepo i hoʻohana ʻia no ka hoʻokuʻu ʻana i ka pale pale wai, ka hoʻohui ʻana i ka pā, ke ʻano hana TAD i kūkulu ʻia i ka hale paʻa, ka paipu prestressed. hale paʻa puʻu, hui pū kila He pūʻulu o nā ʻenehana hou ʻōmaʻomaʻo, mālama i ka ikehu a pili i ke kaiapuni e like me ke kākoʻo, ultra-high pressure jet grouting, a me DMP construction method digital micro-disturbance mixing pile.
Hana pū a kaʻana like i nā ʻano hana kūkulu hou a me nā ʻenehana hou
Ma ka papa kuhikuhi mua o ka halawai, mua, Song Qingjun, hope poʻokela 'enekinia o Shanghai Underground Space a me 'enekinia Design Institute o Huajian Group, a me Wang Boyang, papahana 'enekinia o Shanghai Machinery Construction Group Co., Ltd., i wehewehe i ka prefabricated lalo honua. diaphragm wall technology of TAD construction method, the principle of TAD construction method and E hana ʻia ka hōʻike hālāwai e pili ana i nā ʻano o nā hiʻohiʻona, ke koho ʻana i nā mea hana, ka ʻenehana hana, ka hoʻomaikaʻi ʻana i ke ʻano hana a pēlā aku.
ʻO ke ʻano hana TAD ke ʻano hana o ka pā diaphragm i lalo o ka pā o ka canal-cut assembly. ʻO kēia ʻano hana ka hoʻokomo ʻana i kahi pā paʻa paʻa i hoʻopaʻa ʻia me ka mīkini paʻa mua a me ka mīkini ʻūlū {lock buckle} i waenakonu o ka pā diaphragm canal-cut cement-soil diaphragm e hana i ka paia diaphragm underground. Hoʻohālikelike ʻia me ke kaʻina hana kūkulu hale diaphragm ma lalo o ka honua, ʻo ke ʻano hana TAD nā mea maikaʻi o ka liʻiliʻi o ka noho ʻana, ka hiki ke hoʻololi ikaika, ka wā kūkulu pōkole, a me ka pale ʻana i ke kaiapuni.
Shanghai 'Enekinia Mīkini Co., Ltd., Zhejiang Jitong Ground a me Air Construction Technology Co., Ltd., Zhejiang University Binhai a me Urban Geotechnical Engineering Research Center, Zhejiang Architectural Design and Research Institute, Zhejiang University of Science and Technology, a me Jianhua Building Materials (Kina) ua hoʻokō 'ia i loko o-hohonu 'oihana-university-noiʻi hui 'ana, e lawe systematic pili lehulehu ma ka theoretical helu ana o TAD hana hana, paia panel hoomakaukau, machinery manufacturing, etc. pā.
ʻO ka papa hana ʻelua o ka hālāwai: Ua hana ʻo Kauka Li Qing o Shanghai Underground Space and Engineering Design Research Institute o Huajian Group i kahi hōʻike hālāwai e pili ana i ka ʻenehana micro-disturbance mix pile ʻenehana o ke ʻano hana kūkulu DMP.
Hoʻohana ʻo DMP-I digital micro-disturbance mixing pile (DMP construction method) i ka DMP-I digital micro-disturbance mixing pile machine nā lako kūikawā o Shanggong Machinery, a hoʻohana i ka ʻōnaehana hoʻokele kikohoʻe e hoʻokō i ka mana kūkulu ʻakomi. ʻO ka slurry a me ke kinoea i hoʻokuʻu ʻia mai ke awa grouting (air) e ʻoki i ka lepo, a hui pū i ka sima a me nā mea hoʻōla ʻē aʻe me ka lepo e lilo i puʻu me kahi ikaika a me ka impermeability. Ma o ka mana maʻalahi o ka puʻe kūloko a me ka multi-channel ʻO ka hoʻokuʻu ʻana o ka slurry a me ka pau ʻana o ka paipu drill kūikawā e ʻike i ka haunaele iki o ka lepo a puni ka puʻu i ka wā o ke kaʻina holoʻokoʻa o ka hoʻokumu ʻana o ka puʻu, i kapa ʻia ʻo DMP ʻano hana.
ʻO ka DMP-I digital micro-disturbance mixing pile machine (DMP construction method equipment) he ʻenehana hana hou e hui pū ana i ka mīkini wili pile i hoʻomohala ʻia e SEMW a me nā ʻoihana home kaulana, nā kula, a me nā kulanui, ka mea nui e hoʻoponopono i ke kino puʻu i ka wā o ka ke kūkulu ʻana i nā puʻu huikau kuʻuna. ʻAʻole like ʻole, haʻahaʻa haʻahaʻa o ka ʻikepili, paʻakikī ke kāohi i ka maikaʻi o ke kūkulu ʻana, ʻoi aku ka nui o ka lepo pani, ka haunaele nui o ke kūkulu ʻana, ka haʻahaʻa haʻahaʻa o ka hoʻokumu ʻana o ka puʻu a me nā pilikia ʻē aʻe. Hoʻohana nā mea hana i ka ʻenehana hana kikohoʻe, nona nā hiʻohiʻona o ka palekana kiʻekiʻe a me ka hilinaʻi, ka maikaʻi o ka puʻu kiʻekiʻe, ka haunaele liʻiliʻi i ka puni a puni, a me ka hopena kūkulu kiʻekiʻe. Ma o ka hoʻonohonoho ʻana o ka puʻu GPS, ʻo 850mm ke anawaena o ka puʻu, a hiki i ka hohonu o ke kūkulu ʻana ke hiki i 45m. Hiki i ke kū'ē i ka wā hui ke hoʻomaikaʻi i ka hui like ʻana o ka lepo sima a me ka maikaʻi o ka puʻu. ʻAʻole hiki i nā mea hana ke hoʻohui wale i nā ʻoki ʻoki e like me ka mea e pono ai, e pale i ka pālolo mai ka pipili ʻana i ka paipu drill a hana i nā pōpō lepo, a hoʻemi i ka haunaele i ka hoʻokumu ʻana, akā loaʻa pū kekahi i kahi hoʻolālā kūikawā o nā mea hana wili a me nā mea kākoʻo, a me ka verticality o ka puʻu. hiki ke hoomaluia ma 1/300. Ua maopopo ka pono.
Ua kūpaʻa ʻo SEMW i ka hoʻomohala ʻana a me ke kūkulu ʻana i ke kūkulu ʻana o ka honua a me ka noiʻi ʻenehana kūkulu hale, a ua kūpaʻa ʻo ia i ka hāʻawi ʻana i nā mea kūʻai aku i nā hopena holoʻokoʻa no nā kumu ma lalo o ka honua, e kōkua ana i ke kūkulu ʻana i nā ʻoihana kūloko kūloko, e pili mau ana i ka manaʻo o "nā lawelawe ʻoihana, hana. waiwai" Hoʻomohala pū nā mea kūʻai aku. E hoʻohana ʻo Shanggong Machinery, e like me nā manawa a pau, i kāna hōʻiliʻili hohonu i ke kahua o ka mīkini pahu e hoʻokō pono i nā pono hana o nā mea kūʻai aku, hāʻawi i nā lawelawe ʻoihana no nā mea kūʻai aku, a hana i ka waiwai.
