2024 Tus sau: Howard Calhoun | [email protected]. Kawg hloov kho: 2023-12-17 10:28

Kev tsim kho ntawm ntau lub tsev niaj hnub xav tau qhov yuav tsum muaj ntawm pawg hauv av. Rau lub hom phiaj no, ib pawg tsav tsheb yog siv, uas peb yuav tham txog ntau yam hauv kab lus no. Cia peb kawm nws qhov tsis muaj thiab muaj peev xwm.

Definition

Pile tsav yog lub tshuab tsim tshwj xeeb tsim los tsav ntau pawg rau hauv av. Reinforced qhob pawg tuaj yeem yog puag ncig lossis square. Nyob rau tib lub sijhawm, lawv tau tsim tag nrho lossis sib xyaw. Kev tsav tsheb hauv pawg tuaj yeem tshwm sim tsis tau tsuas yog nyob rau hauv qhov chaw tsim kho, tab sis kuj tseem ntxiv dag zog rau txoj kab nqes, trench, pits, thiab ntxiv dag zog rau ntug hiav txwv.

Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm

Tus neeg tsav tsheb pawg, tsis hais hom rauj nws siv, ua haujlwm raws li cov qauv hauv qab no. Lub tshuab sawv ntawm qhov chaw ua haujlwm thiab, ua tsaug rau nws lub winch, txav pawg npaj rau kev teeb tsa los ntawm lub tsev khaws khoom, thiab tom qab ntawd coj nws mus rau theem ntawm lub taub hau rauj. Tom qab ntawd qhov kev txhawb nqa yog tsau nyob rau hauv txoj hauj lwm ntsug ntawm qhov taw tes, thiab lub tshuab ua rau ob peb lub tshuab. Tom qab ntawd, lub verticality ntawm pawg yog xyuas (yog tias tsim nyog, qhov no parameterkho tau). Tom ntej no, pawg tsav tsheb mus rau hauv av mus rau qhov tob uas tau npaj los yog mus rau qhov tsis ua tiav predetermined, uas yog, mus rau qhov tsawg kawg nkaus ua tau theem ntawm immersion tom qab muaj kev cuam tshuam ntawm qhov kawg 'meter' ntawm kev txhawb nqa nkag mus rau hauv av.

Ntau yam ntawm pawg tsav tsheb

Kev tsav tsheb yog lub luag haujlwm thiab ua haujlwm hnyav heev uas yuav tsum tau mloog, ua siab ntev thiab qee yam kev paub thiab kev txawj ntse. Thiab nws yog nqa tawm los ntawm lub cev copra tshwj xeeb, uas tuaj yeem yog rauj lossis lub vibration exciter.

Rauj, tig, tuaj yeem yog hom hauv qab no:

• Mechanical.
• Steam-air.
• Hydraulic.
• Vibrating.
• Pneumatic.
• Diesel.

Peb yuav nyob ntawm qhov kev xaiv kawg hauv kev nthuav dav ntxiv, txij li nws tau dhau los ua qhov dav tshaj plaws hauv kev tsim kho. Diesel rauj yog qhov yooj yim tshaj plaws thiab txhim khu kev qha piling cuab yeej. Nws ua haujlwm raws li lub hauv paus ntsiab lus no: thaum pawg nyob hauv qab lub taub hau ntawm rauj, nws tau qhib thiab muab tso rau hauv qhov kev txiav txim, uas yog, qhov cuam tshuam yog nqa nrog ib tus miv tshwj xeeb thiab poob qis. Thaum lub caij nplooj zeeg ntawm qhov kev poob siab ntawm lub combustion chamber, roj diesel ignites, tawg thiab tus pin firing tawm mus rau qhov siab. Nws lub caij nplooj zeeg ua rau muaj kev kub ntxhov rau Hnub Caiv. Tag nrho cov txheej txheem no tau rov ua dua mus txog thaum tus neeg tsav tsheb ntawm copra nrog nws pab neeg nres cov khoom siv roj av.

Tubular-type diesel hammers yog siv los tsav cov pob zeb uas muaj zog ntxiv rau hauv txhua qhov av tshwj tsis yog pob zeb. Cov hammers zoo li no muaj peev xwm tsis muaj kev sib tsooua hauj lwm nyob rau hauv ib tug dav dav kub ntau yam: los ntawm -40 mus +40 degrees Celsius, uas tso cai rau lawv mus ua hauj lwm txawm nyob rau hauv lub txias cheeb tsam. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nkag siab tias, zoo li lwm yam diesel units, cov hammers piav qhia yuav tsum tau ua kom sov sov ua ntej ua haujlwm.

Hydraulic rauj

Lub hydrohammer hauv qee qhov kev ntsuas tsis zoo yog qhov zoo dua rau nws cov khoom siv diesel. Tab sis tib lub sijhawm, hydraulic analogue yog kim dua.

Lub hydraulic hom rauj yog ua ntej ntawm lub diesel version hauv cov yam ntxwv hauv qab no:

• Tsawg suab nrov.
• Qab av vibration.
• Higer service life.

Tsis tas li ntawd, lub tshuab hydraulic tuaj yeem tsav cov pawg ze rau cov tsev nyob ze. Qhov yooj yim ntawm kev hloov kho lub zog tso cai rau cov cuab yeej hydraulic txhawm rau txhawm rau lub zog ntawm kev tawm tsam nrog qhov tseeb tshaj plaws, uas feem ntau nyob ntawm cov av ntawm ib cheeb tsam.

Tus nqi ua haujlwm, raws li cov kws tshaj lij, tuaj yeem suav tias yog kev saib xyuas nyuaj thiab kev tsim nyog siab dua uas tus neeg tsav tsheb copra yuav tsum muaj.

Raws li "Yunttan PM-25" kev teeb tsa, cia peb kawm nws cov yam ntxwv:

• Pile ntev yuav tsum tsis pub tshaj 16 meters.
• Tus taw qhia mast yog 19.7 meters ntev.
• Qhov hnyav ntawm qhov poob siab yog 5 tons.
• tag nrho qhov hnyav - 11.7 tons.
• Kev mob stroke ntawm qhov poob siab yog 1 meter 20 centimeters.
• Nyob rau hauv ib feeb tus naj npawb ntawm strokesyog nruab nrab ntawm 40 txog 100.

Tus neeg tsav tsheb pawg txav li cas?

Kev xa khoom thiab kev teeb tsa ntawm copra ntawm nws qhov chaw ua haujlwm yog ua los ntawm kev siv lub iav khiav, uas tuaj yeem yog:

• Chassis log yam.
• Crawler propulsion.
• Rail device.

Lub cav, kis tau tus mob, cov khoom siv rau kev saib xyuas thiab tswj cov cuab yeej ntawm tag nrho cov copra yuav tsum tau muab tso rau ntawm txhua qhov kev qhia tshwj xeeb.

hom kev ua haujlwm platform

Tus neeg tsav tsheb pawg tuaj yeem ua tau ob qho tib si tig thiab kho. Cov qauv ntawm hom tom kawg muaj peev xwm tsav cov pawg tsuas yog nyob ntawm lawv qhov chaw, thiab qhov kev xaiv rotary tso cai rau koj los tsav cov pawg mus rau hauv av ib ncig ntawm thaj tsam ntawm lub tshuab qhov chaw. Rau wheeled headframes, lub kaum sab xis ntawm kev sib hloov yog txwv rau 260 degrees, thiab tracked units muaj peev xwm tig tau 360 degrees.

Kuj, nyob ntawm kev ua haujlwm ntawm copra, lawv tau muab faib ua qhov yooj yim, semi-universal thiab universal.

Universal qauv yog endowed nrog lub peev xwm los kho qhov ncav cuag thiab inclination ntawm lub mast, semi-universal tshuab tsuas yog hloov lub inclination, thiab cov yooj yim sawv daws yuav muaj ib tug ruaj mast thiab yog li ntawd tsuas yog nruj me ntsis ntsug pawg tsav tsheb.

Technical indicators of headframes

Yog tias koj tsis mus rau hauv cov ntsiab lus ntawm tus kheej cov qauv ntawm lub taub hau, ces feem ntau lawv cov kev ntsuas yuav zoo li no:

• Driven pawg tuaj yeem ntev 8 txog 20 meters.
• Load peevthaj tsam ntawm 2 mus rau 21 tons.
• Masts muaj ncav cuag 1-8 meters.
• Hluav taws xob lub cev muaj zog yog 7-96 kW.
• Qhov siab ntawm copra yog 10-28 meters.
• Mast qaij tuaj yeem yog 1: 3 - 1: 10 tangent ntawm lub kaum.

Cov neeg tsav tsheb tus kheej muaj peev xwm tsav pawg ntau yam, suav nrog:

• Nyob zoo ib tsoom phooj ywg.
• Sheath piles.
• Cov ntsiab lus ntawm ntu ntu.
• Square shaped designs.

Qhov kev xaiv ntawm cov khoom siv ntxiv dag zog, tom qab hammered rau hauv av thiab txuas nrog pawg tsav tsheb, nyob ntawm seb pawg tsav tsheb twg yuav siv. Los ntawm txoj kev, pawg tsav tsheb yog qhov hloov pauv tau uas txuas cov pawg ncaj qha mus rau qhov txuas rau kev tsav tsheb.

Pendulum tshuab

Thiab, tus tsav tsheb pendulum yog siv los tsav cov pawg inclined rau hauv av. Qhov no muaj tseeb tshwj xeeb thaum lub sij hawm tsim kho chaw nres nkoj. Cov tshuab zoo li no tau ua tiav tag nrho thiab tso cai rau koj tsav pawg ntawm cov ntoo thiab cov pob zeb ntxiv dag zog ob qho tib si ntsug thiab ntawm ib lub kaum ntse ntse. Hauv qhov no, qhov ntev ntawm cov khoom tuaj yeem sib npaug li 35 meters, thiab qhov hnyav tuaj yeem ncav cuag li 30 tons.

Lub pendulum headframe thaum lub sijhawm ua haujlwm tuaj yeem teeb tsa nws lub boom ntawm lub kaum sab xis uas xav tau thiab feem ntau muaj cov lus qhia telescopic, uas tso cai rau koj txav lub boom thiab tig lub truss nyob rau hauv txoj kab rov tav mus rau 360 degrees.

Nws yog ib qho tseem ceeb kom nkag siab tias kev teeb tsa ntawm lub copra yuav tsum tau muabceev faj tshaj plaws. Kev tso cov lem thiab scaffolds yuav tsum tau ua nrog kev saib xyuas zoo tshaj plaws thiab qhov ua tau zoo tshaj plaws. Cov counterweights tshwj xeeb yog kuaj, tus naj npawb ntawm cov uas yuav tsum tau ua kom muaj kev ruaj ntseg ntawm tag nrho lub tshuab. Thaum lub sij hawm kev thauj mus los, lub rauj yuav tsum nco ntsoov txo qis mus rau qhov qis tshaj plaws thiab ceev ceev kom tsis txhob muaj qhov xwm txheej txaus ntshai lossis raug mob rau cov neeg ua haujlwm. Tsis tas li ntawd, tsis txhob siv cov khoom hnyav hnyav los tsav cov pawg sib tw.
