鋼(gang)(gang)(gang)筋(jin)套(tao)筒(tong)連(lian)接套(tao)筒(tong)使(shi)(shi)用(yong)前(qian)的準備(bei)工作(zuo)：1.選擇相應(ying)的鋼(gang)(gang)(gang)筋(jin)連(lian)接套(tao)筒(tong)。如果連(lian)接鋼(gang)(gang)(gang)筋(jin)的厚度(du)不同，可選擇異徑套(tao)管進(jin)行連(lian)接。2.鋼(gang)(gang)(gang)筋(jin)端部應(ying)平(ping)(ping)整，不得有“馬蹄形”端面。用(yong)鋼(gang)(gang)(gang)筋(jin)平(ping)(ping)切機進(jin)行鋼(gang)(gang)(gang)筋(jin)的切割是很容易(yi)的。3.剝肋預埋后，鋼(gang)(gang)(gang)筋(jin)不得與套(tao)管松脫。露出2-3個螺紋齒，用(yong)扭力扳手擰(ning)緊鋼(gang)(gang)(gang)筋(jin)和套(tao)筒(tong)。4.完整的施工設計圖紙，包(bao)括可能(neng)工作(zuo)的應(ying)急預案等。5.鋼(gang)(gang)(gang)筋(jin)穿線(xian)后，應(ying)將螺紋牙(ya)充分(fen)包(bao)裹，損傷過大時應(ying)及時更換滾輪(lun)，以(yi)免螺紋牙(ya)受力不均影響(xiang)接頭質量。6.鋼(gang)(gang)(gang)筋(jin)穿線(xian)機應(ying)定期進(jin)行維(wei)護保(bao)養(yang)，并加乳(ru)化油，使(shi)(shi)穿線(xian)機保(bao)持(chi)平(ping)(ping)穩(wen)，以(yi)提高穿線(xian)機的使(shi)(shi)用(yong)壽命。
