一切螺栓應在回填之前擰緊，確保波紋的堆疊部分嚴密的嵌套在一起。鋼波紋涵管洛氏硬度洛氏(shi)硬度(du)(du)試驗是用必定的(de)(de)載荷將頂角為120度(du)(du)的(de)(de)金(jin)剛石圓錐(zhui)體或直(zhi)徑為1.588mm的(de)(de)崔火鋼球壓(ya)入被(bei)測樣外表，依據壓(ya)痕的(de)(de)深度(du)(du)確定它的(de)(de)硬度(du)(du)值(zhi)。洛氏(shi)硬度(du)(du)值(zhi)可從洛氏(shi)硬度(du)(du)計刻(ke)度(du)(du)盤上(shang)直(zhi)接(jie)讀(du)出。

鋼(gang)波(bo)紋涵(han)管用(yong)洛氏(shi)(shi)硬度(du)計可以(yi)丈量從軟到硬的各(ge)種不同(tong)資(zi)料，這是由于它(ta)選用(yong)了(le)不同(tong)的壓頭和載荷，組成各(ge)種不同(tong)的洛氏(shi)(shi)硬度(du)標尺(chi)，如(ru)HRA、HRB、HRC等。一般生產(chan)以(yi)HRC（用(yong)120度(du)金剛石(shi)圓錐體作壓頭，載荷為(wei)1500N）用(yong)得多，鋼(gang)波(bo)紋涵(han)管硬度(du)值的標示(shi)辦法與布(bu)氏(shi)(shi)硬度(du)相同(tong)，硬度(du)值的有(you)用(yong)規模為(wei)20~70HRC。

為了確保達到螺栓扭矩的要求值，在回填之前隨機抽取結構上縱向接縫上2%的螺栓，用定扭扳手，定預緊力扭矩340N.m±70N.m，進行抽檢試驗。如果有任一試驗值超出了給定的扭矩規模，則應抽檢一切螺栓的5%。如果上述試驗90%以上滿足要求，則認為安裝是合格的；否則應從頭復核，以確定得到的扭矩值是否滿足要求。//hanihanbj.com/
