Pile tsav tsheb tau siv dav hauv kev tsim kho. Nrog kev pab los ntawm xws li mechanisms, ib tug txhim khu kev qha foundation yog tsim rau lub hauv paus ntawm ntau-storey tsev. Nyob rau hauv cov cheeb tsam uas nyuaj geology, tshwj xeeb tshaj yog nyob rau hauv lub reservoir nyob ze, pawg tsav tsheb ua rau nws muaj peev xwm mus ntxiv dag zog rau cov av thiab nqa tawm kev tsim kho nrog ib tug guarantee tiv thaiv kev poob ntawm cov av.

Piling installation yog siv rau immersion hauv av ntawm kev txhawb nqa rau ntau lub hom phiaj. Hauv kev tsim kho txoj kev, cov tshuab me me txhim kho lub laj kab raws txoj hauv kev, txhawb nqa cov paib thiab ntau yam kev thauj khoom. Tsis tas li ntawd, lawv yog siv los npaj cov laj kab, thaiv, cov pas nrig.

Hauv kev tsim kho pej xeem thiab kev lag luam, cov kev teeb tsa no tsav pawg rau hauv av kom ntxiv dag zog rau cov av. Lawv yog cov pob zeb muaj zog los yog hlau. Lawv tuaj yeem muaj ib seem square lossis lwm qhov profile: channel, I-beam, yeeb nkab.

Ntxiv rau kev tsim cov hauv paus hauv paus rau cov tsev tshiab, xws li kev teeb tsayog siv los ntxiv dag zog rau cov av hauv thaj chaw nrog cov tsev uas twb muaj lawm. Lawv kuj tau siv hauv choj tsev, roj platforms thiab docks.

Muaj ob txoj haujlwm tseem ceeb hauv tus txheej txheem tsav tsheb: txhim kho nws hauv qhov chaw nruj me ntsis ntawm txoj cai lossis lwm lub kaum sab xis tsim nyog rau qhov project thiab, qhov tseeb, plunging nws mus rau hauv av mus rau qhov tob tob. Yog hais tias txoj kev kos npe rau qhov siab ntawm 2-2.5 m yog txaus, ces pawg yog tsav mus rau hauv av mus rau qhov tob txog li 12 m kom ntxiv dag zog rau cov av.

Cov pob zeb ua pob zeb nrog ntu ntawm 350 × 350 mm thiab qhov ntev ntawm 12 m hnyav txog 4 tons. Txhawm rau rub nws mus rau hauv qhov chaw, nqa nws thiab teeb tsa raws nraim ntawm thaj chaw vertically lossis ntawm lub kaum sab xis, yuav tsum muaj cov cuab yeej tshwj xeeb. Xws li ib tug mechanism yuav tsum tau mobile nyob rau hauv thiaj li yuav tsiv mus nyob ib ncig ntawm qhov chaw tsim kho los ntawm qhov chaw ntawm pawg cia mus rau lub point ntawm lawv installation. Nws yuav tsum tau nruab nrog lub siab boom rau ntsug nqa cov khoom hnyav thiab hnyav, muaj qhov dav txaus thiab loj los tuav lub tshuab nws tus kheej.

Koper - kev tsim kho tshuab rau kev txhim kho pawg. Yog hais tias, nyob rau hauv tas li ntawd, nws kuj yog txawm peem rau nrog ib tug rauj rau immersing lawv nyob rau hauv cov av, ces xws li ib tug mechanism yog xam tau tias yog ib tug piling installation. Rauj yog feem ntau ua nrog ib tug diesel los yog hydraulic rauj. Ib qho kev thev naus laus zis ntau dua yog kev vibrational tob ntawm pawg. Nws tuaj yeem tshwm sim ua ke nrog kev nias lossis cuam tshuam.

Cov khoom sib xyaw ua ke tuaj yeem muaj cov khoom siv ntxiv. Feem ntau cov mechanismscov khoom siv drilling yog ntsia. Nws yog ib qho tsim nyog rau kev teeb tsa tus thawj coj zoo hauv cov av uas muaj qhov ntom ntom. Thaum lub sij hawm installation ntawm pawg, cov av yog drilled mus rau qhov yuav tsum tau qhov tob nrog ib tug xyaum. Ib pawg tsav tsheb nruab ib pawg hauv lub qhov dej. Nyob rau hauv nws tus kheej qhov hnyav, nws yog ib feem faus thiab ces hammered rau qhov tob tsim.

Design nta

Cov neeg tsav tsheb sib xyaw ua ke lossis piling rig yog lub tshuab loj heev ntawm kab ntsig lossis lub log tsav nrog lub mast prefabricated los yog boom rau nqa kev txhawb nqa nrog lub winch thiab muab tso rau hauv qhov chaw ua ntej. Nws tuaj yeem ua nws tus kheej los yog thauj los ntawm lub tsheb laij teb. Cov cuab yeej siv los ntawm cov tuam txhab ua lag luam ntawm cov cuab yeej tsim kho yog nruab nrog cov muaj zog thiab ua haujlwm zoo rau kev tuav thiab nqa cov hlau profiled txhawb nqa. Lawv muab tso rau hauv txoj kev vibrational.

Cov cuab yeej sib txawv tuaj yeem ntsia tau rau ntawm cov piling rigs. Feem ntau siv diesel qws lossis tubular hammers. Lawv siv lub zog los ntawm cov roj combustion nyob rau hauv lub chav ua hauj lwm kom ceev qhov tawm tsam. Hydraulic thiab pneumatic hammers kuj tseem siv tau. Nyob rau hauv cov chav no, cov kua thiab compressed cua yog siv los nqa lub nruas, feem. Qee qhov xwm txheej, kev teeb tsa tuaj yeem nruab nrog chav tsev rau kev thim rov qab - rub pawg tawm hauv av. Qhov no siv lub elevator ua ke nrog kev poob siab lossis kev vibration mechanism.

Pile-tsav tsheb rig SP-49

chav tsev no yog tsim los hauv tsevtau siv rau ntau tshaj 25 xyoo. Nws yog siv nyob rau hauv pej xeem, industrial thiab private siv rau kev npaj ntawm pawg thawj coj. Muaj ntau qhov kev hloov kho. Kev sib xyaw piling rigs SP-49D nrog lub tshuab hluav taws xob tsis tuaj yeem tsuas yog nruab cov pawg raws li kev tswj hwm, tab sis kuj tseem tsav lawv mus rau hauv av.

SP-49 ua pov thawj tias yog sab zoo. Nws txawv ntawm maneuverability, txhim khu kev qha hauv kev ua haujlwm, muaj kev ua haujlwm zoo, raug tshuaj xyuas los ntawm lub sijhawm thiab huab cua hnyav. Tsis tas li ntawd, nws yog qhov pheej yig tshaj plaws thiab them nyiaj sai sai rau kev tsav tsheb cov pob zeb ua kom muaj zog ntxiv mus txog 12 m ntev.

Tus SP-49 pawg tsav tsheb yog tsim los ntawm T-10 (T-170) taug qab tsheb laij teb off-road. Nws yog txawm peem rau nrog ib tug pawg-lifting mast uas yuav tsum tau tsiv mus rau kho txoj hauj lwm thiab lub kaum sab xis ntawm inclination. Thaum txhim kho cov cuab yeej drilling, SP-49 pawg tsav tsheb tuaj yeem ua cov dej hauv cov av ntawm ntau qhov ntom ntom, suav nrog cov thawj coj los pab txhawb cov txheej txheem ntawm kev sib tsoo cov kev txhawb nqa.

Pile-tsav rigs: cov yam ntxwv ntawm tus qauv ntawm SP-49

Tag nrho qhov hnyav ntawm chav tsev yog kwv yees li 30 tons, thiab nws yuav txawv nyob ntawm qhov kev hloov kho. Nrog rau qhov hnyav ntawm cov cuab yeej nruab - los ntawm 5 mus rau 8.5 tons. Thaum lub sij hawm kev thauj mus los, lub piling installation muaj ib tug ntev ntawm 10 m, nrog ib tug dav thiab qhov siab ntawm 4.3 thiab 3.5 m, feem. Qhov ntev ntawm txoj haujlwm ua haujlwm yog: ntev × dav × qhov siab - 4.7 × 5 × 18.5 m. Mast nthuav dav thaum kho txoj haujlwm - txog li 0.4 m.

Qhov hnyav ntawm pawg yuav tsum tau nqa - txog li 5 tons, qhov hnyav ntawm rauj- mus txog 7 tons. Tag nrho cov peev txheej - 12 tons. Hloov chaw ua hauj lwm ntawm lub mast mus rau sab xis-sab laug - mus txog 7º, pem hauv ntej-rov qab - mus txog 18º. Cov pawg tsav tsheb nqa ntawm qhov ceev ntawm 16.5 m / min. Productivity per shift - 38 kev txhawb nqa. Suab nrov nyob rau hauv lub cab thiab chaw ua hauj lwm - 80–110 dB.

Pile tsav tswj

Cov neeg ua haujlwm tu vaj tse - 3 tus neeg. Tus neeg tsav tsheb ntawm lub piling installation, ntxiv rau kev tswj ncaj qha ntawm cov tshuab, yog lub luag haujlwm rau kev saib xyuas cov tshuab thiab cov khoom siv thaum lub sijhawm ua haujlwm, txheeb xyuas thiab, yog tias ua tau, tshem tawm cov haujlwm tsis zoo. Nws cov dej num muaj xws li: refueling nrog roj thiab lubricants, kev koom tes nyob rau hauv lub tam sim no thiab teem caij soj ntsuam, kho mechanisms thiab systems ntawm lub installation.

Cov neeg uas muaj daim ntawv tsav tsheb tsav tsheb tau tso cai los ua haujlwm. Lawv yuav tsum muaj kev paub txog cov kev cai rau kev khiav hauj lwm lub installation nyob rau hauv txawv loads thiab nyob rau hauv ntau yam tej yam kev mob. Qhov tseem ceeb sib npaug yog qhov kev paub thiab kev txawj ntse ntawm kev ua haujlwm zoo, ua raws li kev tiv thaiv kev ua haujlwm thiab cov qauv kev nyab xeeb thaum ua haujlwm cov txheej txheem nyuaj.
