Anchoring thev naus laus zis thiab cov qauv tswj hwm zoo rau cov nqaj hlau
- Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm Anchoring cov txheej txheem siv rau cov khoom siv ua kom zoo nkauj pw tsaug zog tsaug zog, thiab cov khoom xaiv yog li cas?
Zoo tib yam qhob ua vaj tse lub siab (lub zog los ntawm C40) feem ntau siv cov txheej txheem SENLFUR ANCHORING txheej txheem. Anchor tau npaj los ntawm kev sib xyaw cov leej faj: Maas: Xuab zeb hauv qhov ntsuas cua sov ntawm 1: 1, melted los ntawm cua sov rau 160 {}} 180℃thiab tom qab ntawd. Nws muaj qhov zoo ntawm tus nqi qis (kwv yees li 2 yuaan ib lub qhov) thiab yog tsim nyog rau kev sib tw (kev sib tw tsawg dua lossis sib npaug nrog 120km / h). Prestressed qhob pw tsaug zog (lub zog kawm C50) yuav tsum siv Resin Anchoring txheej txheem. Anchor tau npaj los ntawm kev sib xyaw ua ke Resin: Tus neeg saib xyuas tus kheej: 1: 0.5, haum rau ntawm lub sijhawm 4,2: Kev xaiv lub hauv paus: Lub qhov phab ntsa ntawm prestine condressed fargers farping (rub rau lub zog Lub resin thauj tog twg rau kev sib raug zoo sib luag nrog lub ntsej muag du (tsis txhob soften ntawm 120 degree), thiab tuaj yeem tiv taus qhov kev kub ceev thiab hnyav.
- Dab tsi yog tus qauv nqi ntawm spike anchoring tob, yuav ua li cas tswj lub anchoring tob, thiab dab tsi yog qhov cuam tshuam kev sib txawv?
Tus Qauv Anchoring Qhov tob: 120 {-}}}}}}}} Nws yuav tsum tau nyiaj rau 60% -70% ntawm qhov kev tsaug tsaug zog tuab kom ntseeg tau tias muaj kev sib cuag tag nrho ntawm lub thauj tog rau nkoj thiab tus neeg tsaug zog. Kev tswj txoj kev: siv ib lub anchoring pwm nrog tso nplai (cov nplai yog qhov tseeb 1 hli), thiab cov pwm qhov siab yog sib xws nrog tus qauv qhov tob; dlhos qhov ntsia hlau nrog cov pwm nruab nrab thaum ntxig kom ntseeg tau tias qhov tob tob yog sib xws nrog cov nplai; Tom qab qhov pib teeb tsa ntawm lub thauj tog rau nkoj, coj mus kuaj Anchoring tob nrog ib qho ntsuas cua tob nrog lub ntsej muag tob, thiab ua haujlwm yog qhov sib txawv tshaj ± 5mm. Kev cuam tshuam ntawm kev cuam tshuam tob: tsis txaus siab (piv txwv li, tsuas yog 130mm anchoring rau prestressed lub zog pestressed) yuav yooj yim dua vim yog kev co rau kev co kab mob kev co; Ntau dhau ntawm qhov tob (piv txwv li, 160mm lub tog anchoring rau cov neeg tsaug zog ib txwm) yuav nkag mus rau hauv qab pw tsaug zog (ua rau 0.2mm), thiab cov kab sib luag hauv qab yog qhov yooj yim rau xeb.
- Qhov kev cuam tshuam ua feem ntawm Spike Anchor muaj dab tsi ntawm anchoring zoo, thiab yuav ua li cas thiaj li yuav ua li cas kom paub tseeb proportioning?
Kev cuam tshuam ntawm Sulphur thauj tog rau nkoj feem sib txawv txawv (1.2: 1) Yuav ua li cas rau lub thauj tog rau nkoj uas tsis zoo nkauj Kev Ceases ua ntu zus (1: 1.2: 3) yuav txo cov kua ntawm lub thauj tog rau nkoj, ua rau voids (ntim ntau dua lossis sib npaug rau 5cm³) thaum lub sijhawm nchuav; Cov xuab zeb ntau dhau (1: 3.5) yuav txo lub zog thauj mus rau lwm lub zog (lub zog compressive los ntawm 40mpa rau 30MPA). Cov kev cuam tshuam ntawm kev cob qhia thauj tog rau nkoj rau lwm tus: Tsis muaj kev rub tawm ntawm kev rub tawm ntawm 65Kn mus rau 50kn; Tus neeg sawv cev ntawm tus neeg sawv cev ntau dhau (4: 1.2: 0.5) yuav ua rau lub sijhawm kho kom luv rau 15 feeb, tsim cov npuas hauv lub thauj tog rau nkoj; Kev ceev dua tus kheej (4: 1: 0.3) yuav ua rau tsis muaj chaw zaum kawg tom qab 24 teev, ua rau nws tsis tuaj yeem ris lub nra. Kev ntsuas kom ntseeg tau tias yog cov khoom siv hluav taws xob ua ntu zus (tshuaj khib rau cov khoom noj rau cov khoom siv Siv lub ntsuas hluav taws xob nplai (qhov tseeb 0.1Kg) rau kev ua ntu zus, thiab kev kwv yees kwv yees kwv yees; Ua 3 teev cov kev xeem blocks (70.7mm × 70.7mm × 70.7mm) rau txhua pob, sim lawv tsuas yog tom qab dhau qhov kev xeem.
- Dab tsi yog cov qauv rau kev rub tawm - tawm cov kab mob meanored, thiab yuav ua li cas ua tsis tau zoo?
Cov Qauv Xeem: Kev rub tawm - tawm ntawm cov spikes yog ntau dua lossis sib npaug {{{} haul railways ntau dua los yog sib npaug rau 70k. Tus nqi thauj khoom thaum sim yog 5kn / min kom tsis txhob ua kom lub zog tsaug zog nrog cov quab yuam uas tseem ceeb. Cov qauv xeem: ① On -} chaw ntawm cov neeg kuaj: piv txwv thiab ntsuas tsawg dua 1 mais; Cov khoom siv khoom siv: Siv lub ntsej muag rub tawm {{13} tawm cov test los siv cov ntsuas hluav taws xob kom txog rau thaum lub zog rub tawm - tawm dag zog; ③ Kev txiav txim Cov ntaub ntawv: Yog tias rub- tawm dag zog yog qis dua tus nqi txheem qauv, nws raug txiav txim raws li tsis tsim nyog. Zuag ntawm cov khoom lag luam tsis tsim nyog: rau kev tsis tsim nyog me ntsis (rub tawm epoxy resin grout rau qhov tsis xws luag, thiab re- kev sim tom qab kho; Rau kev tsis tsim nyog tsis tsim nyog (rub- tawm ntawm lub qhov muag) lossis cov nkoj loj dua li ntawm cov txheej txheem, thiab cov kab nrib pleb Tom qab rov {{{}} anch anch anch anchING, 100% rub-tawm txoj kev xeem yog qhov yuav tsum tau ua kom txhua tus tsim nyog.
- Dab tsi yog cov kev tshwm sim tshwm sim ntawm pob taws hluav taws xob tsis zoo, yuav ua li cas los xyuas lawv, thiab cov qauv kev kho mob yog dab tsi?
Common appearance defects: ① Voids: There are air bubbles or gaps in the anchor, which can be detected by tapping the spike with a small hammer (a crisp sound indicates no void, a dull sound indicates a void); ② Cracks: Cracks appear on the surface of the anchor, which can be detected by visual inspection or a 10x magnifying glass (cracks with length >3mm are unqualified); ③ Spike inclination: The spike is not perpendicular to the sleeper surface, which can be detected by a level (inclination >3 Degree tsis muaj qhov tsim nyog). Kev Kho Mob Cov Qauv: Rau Voids Me Me (Ntim<5cm³), inject modified cement mortar to fill them; for large voids (volume ≥5cm³), re-anchor; for small cracks (length ≤3mm), apply anti-rust paint after cleaning to prevent crack expansion; for large cracks or inclined spikes, remove the spike, clean the hole, and re-anchor. After treatment, appearance inspection and pull-out test must be carried out to ensure the anchor quality meets the requirements.
