Static drilling nzira uye midziyo sumo

Iyo static drilling uye midzi nzira ndeye kushandisa static yekuchera uye midzi yekudyara murwi nzira yekudyara, yakadzika musanganiswa uye yepasi yekuwedzera grouting kusanganisa, uye pakupedzisira kudyara prefabricated piles, zvinoreva pre-tensioned prestressed prestressed kongiri slub piles (PHDC), pre- tensioned Yakasiyana zvirevo uye mhando dze prestressed kongiri pombi mirwi (PHC) uye inoumbwa yakasimbiswa prestressed kongiri pombi mirwi (PRHC) inosanganiswa mumisanganiswa yakasiyana siyana kuti isangane nezvinodiwa zvekugadzira, uye inoitwa zvinoenderana nekuchera, kuwedzera pasi, grouting, kuisirwa uye mamwe maitiro. . Kuvaka nzira yemurwi nheyo. Nekuda kwehunhu hwenzira yekuvaka yeiyo static yekuchera uye midzi murwi, murwi wemuviri unogona kupfuura nepakati akasiyana geological interlayers, uye dhayamita remurwi i500 ~ 1200mm. Parizvino, kudzika kwekuvaka kwepamusoro kunogona kusvika pamamita makumi masere nemashanu pasi pevhu, uye murwi wekunyura kwemuchina mumwe chete unogona kusvika kupfuura 300m pazuva, uye hupfumi hwehupfumi hwakakwira. kune mamwe marudzi emirwi.

1. Hunhu hwekuvaka nzira

①Hapana kuburitsa ivhu, hapana kuzunguzika, ruzha rwakaderera; kugadzirisa matambudziko ekuvaka echinyakare madhaka anochengeta murwi wegomba kudonha kwemadziro, kudzora madhaka, uye kuburitsa madhaka;

② Yakasarudzika tekinoroji yekuwedzera yepasi, dhayamita yekuwedzera yepasi ndeye 1 ~ 1.6 nguva yedhayamita yegomba, kureba kwepasi kunosvika katatu kwedhayamita yekuchera, mhando yemurwi yakanaka, murwi wepamusoro unodzoreka, uye mhando yekuvaka. iri nyore kudzora;

③Dyarai murwi wagara wagadzirwa muchibhorani, uye ivhu resimende rinosimba kuita simende-yakaputirwa nevhu rakaomarara muviri wemurwi, uye chekunze simende slurry ine zvakakosha kudzivirira pamutumbi wemurwi;

④Yakanyanya kusimba yakatwasuka compression, kudhonza uye yakachinjika mitoro kuramba;

Kuburikidza nekushandiswa kwemhando dzakasiyana dzemirwi senge bamboo piles uye composite yakasimbiswa mirwi, pamwe nekuwedzera kwepasi uye grouting matekiniki, kudzvanya, kudhonza uye yakachinjika kutakura kugona kweiyo mirwi nheyo inovandudzwa zvakanyanya;

⑤ kuchengetedza simba uye kuchengetedza kwezvakatipoteredza;

Kuenzaniswa nemirwi yakafinhwa pasi pemamiriro akafanana: kuchengetedza mvura yekuvaka 90%, kushandiswa kwesimba kuchengetedza 40%, kuyerera kwedhaka kunoderedza 70%, kubudirira kwekuvaka kunowedzera 50%, kuchengetedza mari 10% ~ 20%;

⑥diversified design;

Zvinoenderana nehunhu hwekushushikana kwemapile, marudzi akasiyana emirwi anogona kusanganiswa, anotevera:

2.Process musimboti

Iyo gomba-inogadzira nzira yekusanganisa pombi yekuboorera uye auger drill pombi mukushanda kwakaoma inogamuchirwa, gomba rinoboorwa zvinoenderana nekudzika kwedhizaini, uye magumo emurwi anodzokororwa zvinoenderana nehukuru hwekugadzira (dhayamita uye kureba). Mushure mekugadzirisazve kwapera, murwi unopera sement slurry uye Iyo simende inotsvedza yakatenderedza murwi inodonhedzwa uchigadzira. Mushure mekunge kuchera kwapera, murwi unosimwa padanho rekugadzira nekuzvimiririra kwemurwi, uye iyo yepipi yepipi uye simende slurry yakatenderedza murwi inosimbiswa, kuitira kuti murwi, muromo wemurwi uye simende inotsvedza. murwi wacho wakaoma. Gadzirai muviri uye itai simba rekubereka pamwe chete.

3. Nzira yekuvaka

Iyo static yekuchera uye kudzika midzi nzira yekuvaka ndeye kushandisa yakakosha SDP yekuchera rig kuchera makomba zvinoenderana nezvinodiwa zvekugadzira. Pasi pegomba rinodzokororwa maererano nehupamhi hwakagadzirwa uye urefu. Simudza chibooreso, uye mushure mekunge grouting yapera, vimba nekuzviremera kwemurwi kuti uise murwi munzvimbo yekugadzira, uye simbisa simende inotsvedza pamucheto wemurwi uye kutenderedza murwi, kuitira kuti murwi uye wakaomeswa. ivhu rakabatanidzwa. Kutakura masimba emapiles kunonyanya kuwanikwa nekukweshana kwemurwi uye pile tip resistance. Iyo static yekuchera uye midzi yekuvaka murwi nzira yekuvaka inowedzera kutakura kugona kwepipi yepipi nekuwedzera pazasi pepipi yemurwi, uye inowedzera kupokana kwemurwi wedivi nekupinza simende slurry mudivi remurwi, izvo zvinogona kupa kutamba kwakazara kune mabhenefiti esimba repamusoro remuviri wakagadzirwa murwi uye kuvandudza kugona kwekubereka kweiyo nheyo.

Matanho ekugadzira:

Drilling: Kudhira rig positioning, kusarudza kukurumidza kuchera kwakakodzera maererano nemamiriro ezvinhu e geological, panguva yekuchera, kupinza mvura kana bentonite musanganiswa maererano nemamiriro ezvinhu e geological, kucheka muviri wegomba nekudzivirira rusvingo;

Kuwedzera kwepasi: Mushure mekucheka kwapera, pasi pemurwi unovhurwa kuti uboore makomba ekuwedzera bapiro kuburikidza nehunyanzvi controllable hydraulic tekinoroji, uye pasi inowedzerwa muzvikamu zvinoenderana neyakaiswa yekuwedzera bapiro dhayamita. Uye kuburikidza nechishandiso chekutonga chekutarisa mamiriro ekuwedzera epasi munguva chaiyo;

Pile end simende slurry jekiseni: Mushure mekuwedzera kwepasi kwapera, murwi wekupedzisira simende slurry inoiswa jekiseni, uye dhiri rekuchera rinodzokororwa kusimudzwa nekudzikiswa panguva yejekiseni kuti ive nechokwadi chekuti zvikamu zvese zvekuwedzera zvepasi zvakabaiwa uye murwi wekupedzisira simende slurry yakafanana. ;

Jekiseni resimende slurry rakatenderedza murwi uye kuburitsa chibooreso: Mushure mejekiseni resimende slurry pamagumo emurwi, tanga kuburitsa pombi yekuboorera, jekiseni simende slurry kutenderedza murwi uye simbisa kakawanda;

Kudyara mirwi uye kuunza mirwi: Mushure mekunge chidhirowa chaburitsa pombi dzese dzekuchera, tanga kudyara mirwi. Munguva yekudyara mirwi, tarisa chero nguva kuti uve nechokwadi chekumira kwemurwi uye uve nechokwadi chekudzika kwakadzika kwekudyara mirwi;

Shift: Enda kune inotevera mirwi chinzvimbo uye dzokorora matanho ari pamusoro;

Chechina, chiyero chekushandiswa kwenzira yekuvaka

①Inokodzera kutakura vertical compression, kudhonza uye yakachinjika mitoro;

② Ivhu rakabatana, silt, ivhu rejecha, ivhu rinozadza, rakapwanyika (gravel) ivhu rematombo, uye matombo ematombo ane mamiriro ezvinhu akaoma e geological, akawanda interlayers, kusaenzana kwemamiriro ekunze, uye kuchinja kukuru mukuoma uye kupfava;

③Kana paine zvivakwa (zvimiro) kana mapaipi epasi pevhu uye zvimwe zvivakwa zveinjiniya padyo nenzvimbo yekuvaka, kudzvanya kwevhu kunoda kudzorwa;

④ Hunhu hwevhu hwakaomera mirwi yakabhowekana kuita makomba, sejecha gobvu nematombo akachinjika kana ivhu resiriri rine hunyoro hwakanyanya (kudzoreredza ivhu);

⑤ Kudzika kwekutakura stratum kunosiyana zvakanyanya, uye zvakaoma kutonga stratum; hwaro hwevhu rakapfava, hwaro husina tambo yakakodzera inotakura;

⑥ Kune ekare mirwi nheyo pasi pevhu uye slag layer inopfuura 3 metres yakazadzwa pamusoro.

5. Static drilling uye rooting nzira midziyo

Iyo static drilling uye midzi nzira michina inonyanya yekuvaka nzira yekuchera rig ine murwi furemu. Pakutanga, yakashandiswa ne-single-track pile furemu yekuvaka, iyo yaida kuwedzerwa kwakawanda kwemapombi ekuchera, uye kubudirira kwekuvaka kwaive kwakaderera. Iye zvino inonyanya kuve neyakaviri-track murwi furemu, uye maviri ekuvaka nzira yekuchera madhiri anomiswa panguva imwe chete. Kuboora neimwe nzira Kana danda rashandiswa, kudzika kunogona kusvika 85m, izvo zvinovandudza zvakanyanya kushanda kwekuvaka.

Iyo static yekuchera uye midzi nzira michina inotora yakangwara yekuvaka manejimendi software yekutarisa maitiro ekuvaka munguva chaiyo kuti ive nechokwadi chekuvaka mhando. Yakasiyana-siyana yekuvaka data inoratidzwa zvakajeka pachiratidziro uye inochengetwa otomatiki.

Chibooreso chinotora tekinoroji yepamusoro yeoiri yepasi yekuwedzera tekinoroji, iyo yepasi yekuwedzera dhayamita ndeye 1 ~ 1.6 nguva yedhayamita yekuchera, uye yepasi yekuwedzera kureba ndeye 3 nguva yedhayamita yekuchera; maererano nemamiriro akasiyana e geological, chivakwa chinogona kusarudza general-chinangwa drill kana yakakosha drill;

Universal drill bit: yakakodzera kune ivhu rejecha

Special drill:

Mumakore achangopfuura, iyo static drilling midzi nzira yakashandiswa zvakanyanya muShanghai, Ningbo, Hangzhou nemaguta akapoterera, ichipa dzimwe sarudzo dzekuvaka nheyo dzemurwi, uye zvine chekuita nekuvaka zvimiro uye tekinoroji zviyero zvakagadziridzwa zvakare mushure meimwe. Rudzi rutsva rwemurwi nheyo yekuvaka nzira yakasvibira uye ine hushamwari kwezvakatipoteredza, ine hunyanzvi hwekuvaka uye yakanaka yekugadzira mirwi, uye yakakodzera kukwidziridzwa.
