7.Izvo zvinhu zvinogona kudzokororwa uye kushandiswazve kwe20-30 nguva mumabasa enguva pfupi.
8.Kuenzaniswa nezvimwe zvivakwa zvega, madziro akareruka uye ane hukuru hwekuchinjika kune deformation, iyo yakakodzera kudzivirira uye kurapwa kweakasiyana geological njodzi.
Application
Basa, chitarisiko uye kukosha kunoshanda ndiyo miyero inoshandiswa nevanhu pakusarudza zvinhu zvekuvaka nhasi.Mirwi yesimbi yesimbi inopindirana nemapoinzi matatu ari pamusoro apa: zvinhu zvezvikamu zvayo zvekugadzira zvinopa chimiro chakareruka uye chinoshanda, chinosangana nezvose zvinodiwa zvekuchengetedzwa kwemaitiro uye kuchengetedzwa kwezvakatipoteredza, uye zvivako zvakapedzwa nesimbi mapepa ane kukwezva kukuru.
Kushandiswa kwesimbi mapepa mirwi kunopfuurira uye kunosvika kuindasitiri yese yekuvaka, kubva pakushandiswa kwechinyakare chekuchengetedza mvura mainjiniya uye tekinoroji yevagari, pamwe nekushandiswa kwenjanji uye tramway kusvika pakushandiswa kwekudzora kusvibiswa kwezvakatipoteredza.
Kukosha kunoshanda kwemapuranga emirwi yesimbi kwakaratidzwa mukugadzirwa kwezvinhu zvitsva zvakawanda, zvakadai se: zvimwe zvivako zvakashongedzwa;Metal ndiro yakagadzirwa ne hydraulic vibratory pile driver;Yakavharwa sluice uye fekitori pendi kurapwa.Zvinhu zvakawanda zvinovimbisa kuti simbi yesimbi mirwi inochengetedza imwe yeanonyanya kubatsira yekugadzira chikamu chechikamu, ndiko kuti, haisi kungoenderana nekunaka kwemhando yesimbi, asiwo inobatsira pakutsvagisa nekusimudzira musika wesimbi simbi;Inobatsira kune optimization dhizaini yehunhu hwechigadzirwa kuti isangane nezvinodiwa nevashandisi.
Kuvandudzwa kwechisimbiso chakakosha uye overprinting tekinoroji muenzaniso wakanaka weizvi.Semuenzaniso, HOESCH patent system yakavhura munda mutsva unokosha wesimbi sheet sheet mukudzora kusvibiswa.
Sezvo HOESCH simbi yesimbi murwi yakashandiswa seyakamira yakavharwa madziro ekuchengetedza muna 1986 kuchengetedza ivhu rakasvibiswa, zvakaonekwa kuti murwi wesimbi wesimbi unozadzisa zvese zvinodiwa kudzivirira kubuda kwemvura uye kusvibiswa.Zvakanakira zvesimbi mapepa mirwi semadziro ekuchengetedza zvishoma nezvishoma anoshandiswa zvakanyanya mune mamwe minda.
Zvinotevera ndezvimwe zvinonyanya kushanda geotechnical engineering uye mashandisirwo enzvimbo yekushandiswa kwesimbi mapepa mirwi:
* Cofferdam
* Rwizi mafashama diversion uye kutonga
* Mvura yekurapa system fenzi
* Kudzora mafashamo
* Enclosure
* Dike rekudzivirira
*Kudzoreredzwa kwemahombekombe
* Tunnel yekucheka uye tunnel pekugara
* Breakwater
* Weir wall
* Slope kugadzirisa
* Baffle wall
Zvakanakira kushandisa simbi sheet pile fence:
* Hapana kuchera kunodiwa kuderedza kuraswa kwemarara
* Kana zvichidikanwa, murwi wesimbi wesimbi unogona kubviswa mushure mekushandisa
* Haina kukanganiswa netopography uye yakadzika pasi pemvura
* Kuchera kusingaenzaniswi kunogona kushandiswa
* Kuvaka kunogona kuitwa muchikepe pasina kuronga imwe saiti
Kuvaka Maitiro
Gadzirira
1.Kugadzirira kwekuvaka: usati watyaira murwi, iyo notch pamurwi wepipi ichavharwa kuti irege kusvinwa ivhu, uye muromo wekuvhara uchaputirwa nebhota kana mamwe mafuta.Kune simbi pepa mirwi iyo yave isisagadziriswe kwenguva yakareba, yakaremara yekiyi muromo uye yakanyanyisa kuita ngura, inofanirwa kugadziriswa nekugadziriswa.Kune akabhenda uye akaremara mirwi, anogona kugadziriswa ne hydraulic jack jacking kana kuomesa moto.
2.Chikamu chechikamu chekutyaira kwemurwi.
3.Panguva yekutyaira mirwi.Kuti ive nechokwadi chekumira kwesimbi mapepa mirwi.Shandisa ma theodolites maviri kudzora mumativi maviri.
4.Nzvimbo uye kutungamira kwekutanga uye yechipiri simbi mapepa mapeji kuti ifambiswe ichave yakarurama, kuitira kuti uite basa rekutungamira template.Naizvozvo, kuyerwa kuchaitwa kamwe chete pa1m yekutyaira, uye iyo yekusimbisa kana simbi ndiro ichaiswa welded nerutsigiro rwepurlin rwekugadzirisa kwenguva pfupi mushure mekutyaira kune yakafanotemerwa kudzika.
Design
1. Kusarudzwa kwekutyaira nzira
Nzira yekuvaka yesimbi mapepa emapuranga ndiyo nzira yekufambisa yakasiyana, inotanga kubva kune imwe kona yemadziro emadziro uye inotungamirirwa imwe neimwe (kana maviri muboka) kusvika pakuguma kweprojekti.Mabhenefiti ayo ari nyore uye nekukurumidza kuvakwa uye hapana kudikanwa kwezvimwe zvitsigiro zvekubatsira.Zvayakaipira ndezvekuti zviri nyore kurerekera murwi wepepa kune rimwe divi, uye zvakaoma kugadzirisa mushure mekuunganidza kukanganisa.Naizvozvo, iyo yakaparadzana yekutyaira nzira inongoshanda kune iyo kesi iyo iyo inodiwa yepepa murwi madziro haina kukwirira uye kureba kwepepa murwi idiki (senge isingasviki 10 m).
2.Iyo skrini yekutyaira nzira ndeyekuisa 10-20 simbi simbi mirwi mugwara furemu mumitsara, wobva waatyaira mumabhechi.Panguva yekutyaira, simbi yesimbi inoturikidzana kumigumo yese yemadziro emadziro ichafambiswa kune dhizaini yakakwira kana imwe kudzika kuti ive yekumisikidza mapepa mirwi, yobva yafambiswa nepakati mumatanho e1/3 uye 1/2 pepa murwi kureba. .Zvakanakira iyo skrini yekutyaira nzira ndeiyi: inogona kuderedza kuunganidzwa kwekukanganisa kwekukanganisa, kudzivirira yakawandisa kurerekera, uye zviri nyore kuwana kuvharwa uye kuve nechokwadi chekuvaka kweiyo pepa murwi wemadziro.Izvo zvisingabatsiri ndezvokuti kukwirira kwekuzvimiririra kwemurwi wakaiswa kwakanyanyisa, uye kutarisa kunofanira kubhadharwa kune kugadzikana uye kuchengetedzwa kwekuvaka kwemurwi wakaiswa.
3.Kutyaira kwesimbi mapepa mirwi.
Munguva yekutyaira mirwi, nzvimbo yekutyaira uye kutungamira kwekutanga neyechipiri simbi mapepa mapiru anotyairwa anofanirwa kuve nechokwadi.Inogona kuita basa rekutungamira template.Kazhinji, inofanira kuyerwa kamwe chete 1m imwe neimwe ichityairwa.Kuvakwa kwekona uye kuvharwa kwekuvhara kwesimbi pepa murwi kunogona kutora yakakosha-yakaumbwa pepa murwi, nzira yekubatanidza, nzira inopindirana uye axis kugadzirisa nzira.Kuti uve nechokwadi chekuvakwa kwakachengeteka, zvinodikanwa kuti utarise uye uchengetedze akakosha mapaipi uye yakakwirira-voltage tambo mukati mechikamu chekushanda.
4.Kubviswa kwesimbi mapepa mirwi.
Paunenge uchidzosera gomba rekutanga, murwi wesimbi wesimbi unoburitswa kuti ushandiswe zvakare mushure mekupedza.Pamberi pekuchera, kudhirowa kutevedzana, nguva yekubvisa uye nzira yekurapa gomba resimbi pepa mirwi ichadzidzwa.Kuti ukunde kupokana kwemapepa mirwi, zvinoenderana nemuchina wekudhonza murwi unoshandiswa, nzira dzekudhonza murwi dzinosanganisira kudhonzwa kwemurwi, kudhonza murwi uye kudhonza murwi.Panguva yekushanda kwekubvisa, teerera kutarisa uye kuchengetedza zvakakosha mapaipi uye high-voltage cables mukati mechikamu chekushanda.[1]
Equipment
1.Impact kuunganidza muchina: nyundo yekudonha yemahara, sando yemhepo, sando yemhepo, hydraulic sando, dhiziri sando, nezvimwe.
2.Vibratory pile kutyaira muchina: Rudzi urwu rwemuchina unogona kushandiswa kutyaira uye kudhonza mirwi, uye inowanzoshandiswa ndeye vibratory murwi kutyaira uye kudhonza sando.
3.Vibration uye kukanganisa murwi wekutyaira muchina: rudzi urwu rwemuchina wakashongedzerwa nerutsigiro rwemashini pakati pemuviri weiyo vibration pile mutyairi uye clamp.Kana iyo vibration exciter inogadzira kukwira nekudzika vibration, inoburitsa simba rekuita, iro rinovandudza zvakanyanya kushanda kwekuvaka.
4.Static pile kutyaira muchina: dzvanya pepa murwi muvhu ne static force.
