Thaum tso lub hauv paus rau cov tsev ntawm cov av tsis muaj zog thiab txav mus, cov ntsiab lus tshwj xeeb yog siv - cov khoom sib xyaw ua ke. Ua tsaug rau qhov no, cov qauv tau txais lub zog tsim nyog ntawm cov av tsis ruaj khov. Cov ntsiab lus yog ua los ntawm cov ntoo, pob zeb, hlau, tab sis cov pob zeb muaj zog yog qhov xav tau ntau tshaj plaws.
Design Advantages
Qhov zoo ntawm cov khoom pawg muaj xws li cov ntsuas hauv qab no:
- Durability.
- siab zog.
- No defects.
- Muaj peev xwm ua tiav hauv av hauv qhov ntim tsawg kawg thaum lub sijhawm teeb tsa.
Tab sis qhov tseem ceeb tshaj plaws, cov pob zeb ua vaj tse yog tsis ntshai ntawm cov tshuaj lom neeg thiab kev xeb, uas yog qhov tseem ceeb heev thaum siv cov khoom siv rau kev teeb tsa rau thaj av uas cov dej hauv av nce ze rau saum npoo.
Scope of application
Muaj ob lossis ntau ntu, cov pob zeb ua kom muaj zog tuaj yeem muaj qhov ntev ntev li ntawm 36 m.cov khoom muaj peev xwm txwv thiab tsis tuaj yeem nruab lawv. Qhov tseeb yog tias pawg ua los ntawm cov khoom siv yuav tsum nkag mus tob rau hauv av kom txog rau thaum lawv so tawm tsam cov av uas muaj qhov ntom ntom. Txwv tsis pub, lawv siv tsis tuaj yeem muab qhov kev ruaj ntseg, thiab tom qab ntawd lub tsev yuav sag thaum lub sijhawm ua haujlwm.
Ceeb toom: cov av tsis ruaj khov yog peatlands thiab peaty av, silty thiab clayey av. Nws tsis tuaj yeem tsim cov tsev rau lawv yam tsis siv cov khoom siv.
Cov pawg sib xyaw yog siv tsis yog rau kev tsim kho vaj tse tshiab xwb, tab sis kuj rau kev tsim kho ntawm cov uas twb tau ua haujlwm lawm. Ua li no, ntawm ib qho khoom uas muaj qhov txwv tsis pub siv thiab tsis tuaj yeem siv cov khoom analogues, lawv txhawb lub hauv paus ntawm lub tsev nrog kev txhawb nqa ntxiv. Feem ntau, cov qauv siv uas muaj ntau qhov chaw, txhua qhov muaj qhov tsawg kawg nkaus ntev.
Siv cov khoom siv ntxiv dag zog los ntawm ntau ntu thiab qhov uas nws tsis tuaj yeem xa cov qauv ntev vim txoj kev tsis tsim nyog lossis kev thauj mus los. Siv cov khoom ntawm hom no thiab cov tuam txhab tsim kho uas tsis muaj pawg tsav tsheb tsim los tsav cov qauv, qhov ntev yog los ntawm 12 m.
Design nta
Raws li GOST, cov pawg sib xyaw yog ob qhov sib koom ua ke - sab sauv thiab qis. Cov khoom raug tsim nyob rau hauv ntu nram qab no:
- Nrog qhov ntev 14-24 m - 30 x 30 cm.
- Nrog qhov ntev 14-28 m - 40 x 40 thiab 30 x 30 cm.
Qhov sab sauv thiab qis ntawm cov khoom tuaj yeem muaj qhov ntev los yog sib txawv. Piv txwv li, nyob rau hauv cov khoom nrog ib seem ntawm 0.3 x 0.3 m, qhov qis yuav yog los ntawm 7 mus rau 12 m. Qhov increment yog 1 meter. Cov pawg uas muaj txoj kab uas hla ntawm 0.4 x 0.4 thiab 0.3 x 0.3 m muaj qhov ntev ntawm qhov qis ntawm 8 m, thiab qhov siab tshaj plaws ntawm 14. Qhov ntev ntawm cov seem yog los ntawm 5 mus rau 12 thiab los ntawm 6 mus rau 14 meters, feem..
nthuav dav tseem ceeb: muaj qhov taw qhia ntawm ntu qis uas tso rau hauv av. Nws yog ib qho tsim nyog los txhim kho qhov ua tau zoo ntawm cov khoom nkag mus rau hauv av thaum tsav tsheb lossis indenting.
Txoj kev txuas rau tus kheej cov ntsiab lus
Sib cais ntawm cov pawg sib xyaw tau koom nrog hauv ib txoj hauv kev hauv qab no:
- Nrog kev pab cuam ntawm kev sib txuas ntawm lub khob kos.
- Siv ib daim ntawv steel pad uas compresses lub chim, uas yog txuas los ntawm ib tug weld.
- Txhob qhov chaw yog bolted ua ke.
- Tau daim kab xev kaw, jig lossis so ntawm qhov tseem ceeb protrusions.
- Siv lub xauv xauv.
- Pin txuas.
- Kev siv cov nplaum siv lub zog siab, uas txhim kho qhov kev txhawb nqa protruding nyob rau hauv lub mounting qhov nrog rau sab sauv.
Txoj kev ntseeg siab tshaj plaws ntawm cov txheej txheem no yog kev sib txuas tus pin thiab kev siv lub khob welding - lawv yog cov feem ntau tiv taus deformation.
khoom cim
Raws li cov txheej txheem thev naus laus zis tau muab rau hauv daim ntawv GOST No. 19804, cov khoom hauv qab no tau tsimComposite pawg series 1.011.1-10:
- Nyob zoo ib tsoom phooj ywg.
- Square square designs.
- Sheath piles.
Txhua hom qauv tsim raws li cov qauv teev tseg hauv cov ntaub ntawv cais:
- Hollow cov khoom thiab pawg-plhaub (lub cev pob txha yog ua los ntawm cov uas tsis yog-stressed reinforcement) yog tsim raws li qhov yuav tsum tau teev nyob rau hauv GOST No. 19804.6-83.
- Pile-plhaub, cov tub ntxhais uas yog ua los ntawm prestressed thiab tsis-prestressed reinforcement - GOST No. 19804.91. Cov khoom raug tso cai rau kev teeb tsa hauv txhua qhov kev tsim kho kev lag luam. Qhov tshwj xeeb yog hydraulic engineering sector.
- Cov khoom lag luam nrog ib ntu square yog tsim nrog cov thav duab ua los ntawm cov tsis muaj kev ntxhov siab thiab kev txhawb nqa prestressed raws li daim ntawv GOST No. 19804-2012.
Txhua pawg sib xyaw muaj kev sib koom ua ke kos npe. Hom cim - Sp260.30. SV. Lub npe yog deciphered raws li nram no:
- SP - reinforced pob zeb hollow pawg nrog ib square seem. Yog tias lub npe C yog tam sim no, qhov no yog cov khoom lag luam, yog tias CO yog lub plhaub pawg, SC yog cov qauv hollow ntawm cov kab hla hla.
- 260 - qhov taw qhia ntawm tag nrho qhov ntev ntawm txhua qhov ntawm cov khoom hauv dm.
- 30 - txoj kab uas hla ntawm lub cev hauv centimeters.
- Kev tsim hom kev sib txuas. SW - welded sib koom.
Ntxiv nrog rau cov npe saum toj no, kuj tseem muaj cov ntawv luv ntawm cov cim. Nws taw tes rau ib feem ntawm cov qauv. Piv txwv li: HC yog qhov hauv qab, BC yog sab saum toj, thiab A3 yog nws chav.
Immersion Technology
Designs tog rau hauvav nrog hydraulic lossis diesel rauj. Nws yog nruj me ntsis txwv tsis pub siv vibrators vim qhov tseeb tias cov welded pob qij txha ntawm tus ncej tuaj yeem deformed los ntawm cov nyhuv vibration. Txhawm rau pab txhawb kev nkag mus ntawm cov av ntom ntom, nws raug nquahu kom siv tus thawj coj drilling txoj kev. Daim ntawv thov ntawm txoj kev no yuav pab txo cov av tiv thaiv. Qhov no yog qhov tseem ceeb heev yog tias koj yuav tsum tau tsav cov pob zeb sib xyaw ua ke mus rau qhov tob ntawm 20 meters lossis ntau dua. Txhawm rau kom paub meej txog kev nkag mus ntawm cov qauv, lawv kuj tseem siv cov cuab yeej excavator nrog lub crane boom. Qhov no yuav ua rau kom lub installation nrawm dua, vim tias tus neeg tsav tsheb pawg tsis txav cov khoom ntawm qhov chaw tsim kho.
