Cov Khoom Xaiv thiab Anchoring Txheej Txheem Ntawm Txoj Kev Spikes
- Dab tsi yog qhov txawv ntawm spikes rau cov qhob tsaug zog pw thiab khau ntoo?
Qheb tsaug zog siv xov kab (40mnb, tensile ntau dua los yog sib npaug ntawm kev sib txhuam (rub tawm ntawm kev sib txhuam (rub tawm ntau dua lossis sib npaug nrog 40kn) {9} Spikes muaj cov xov helical (10mm suab, 1 {14. 5 hli qhov siab) rau cov tshuab xauv; Zoo tib yam spikes muaj cov shaft du thiab mushroom hau (30mm hla) los tiv thaiv rub tawm.
- Dab tsi yog "cov ntsiab lus siv lub caij ntuj no" rau cov neeg Sulfur Anchoring?
Nyob rau lub caij ntuj no (<5℃), sulfur anchoring requires: ① preheat sleeper holes to 30-40℃ (hot air gun); ② mix sulfur:cement:sand:paraffin=1:0.8:1.3:0.04, heat to 180-200℃ (slight smoke); ③ insulate with quilts for 2h after anchoring. A northeast project without preheating had average pull-out of 45kN, requiring full rework and ¥300,000 loss.
- Dab tsi yog "Kev kho tau ceev kom zoo" ntawm resin-anchored spikes?
Resin Anchors (e {{{0} g}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} ② Ntxig Resin thauj tog rau nkoj thauj tog rau nkoj (φ28mm, 150 hli ntev); ③ Tig Spike mus rau hauv qab thiab tos kom kho tau . ib tug ciav hlau khi rau hauv 30 feeb, txuag 4 teev thauj Anchoring}
- Dab tsi yog lub hauv paus rau xaiv "tiv thaiv corrosion corrosion" rau spikes?
Cov chaw dej hiav txwv Tsoomfwv Nquag / Tswb Siv Nyiaj Txiag
- Yuav ua li cas loj "Skewness" cuam tshuam rau txoj kev?
Spike Skewness yuav tsum tau tsawg dua lossis sib npaug rau 1℃(kaum sab xis (lub kaum-} . ② 15% rub-tawm quab yuam kom txo; Taster nyuaj installation. Qhov chaw tsim kho nrog kev kuaj xyuas (qhov tseeb} {{}}
