 ;       盾(dun)構(gou)(gou)(gou)管(guan)片(pian)(pian)(pian)(pian)螺栓(shuan)(shuan)是一種(zhong)特殊的(de)(de)(de)緊固件(jian)，主要用(yong)(yong)在隧(sui)(sui)(sui)(sui)道工程(cheng)中(zhong)，盾(dun)構(gou)(gou)(gou)掘進機掘進過程(cheng)中(zhong)用(yong)(yong)來(lai)連接(jie)管(guan)片(pian)(pian)(pian)(pian)的(de)(de)(de)。通過盾(dun)構(gou)(gou)(gou)管(guan)片(pian)(pian)(pian)(pian)螺栓(shuan)(shuan)的(de)(de)(de)連接(jie)，幾個拱形(xing)的(de)(de)(de)管(guan)片(pian)(pian)(pian)(pian)就可以連接(jie)成一個圓形(xing)來(lai)支(zhi)撐起整個隧(sui)(sui)(sui)(sui)道表面，所以叫盾(dun)構(gou)(gou)(gou)管(guan)片(pian)(pian)(pian)(pian)螺栓(shuan)(shuan)，還可以叫管(guan)片(pian)(pian)(pian)(pian)連接(jie)器(qi)，由于盾(dun)構(gou)(gou)(gou)管(guan)片(pian)(pian)(pian)(pian)螺栓(shuan)(shuan)是專門用(yong)(yong)于盾(dun)構(gou)(gou)(gou)隧(sui)(sui)(sui)(sui)道的(de)(de)(de)原(yuan)因，所以又叫盾(dun)構(gou)(gou)(gou)隧(sui)(sui)(sui)(sui)道管(guan)片(pian)(pian)(pian)(pian)螺栓(shuan)(shuan)或盾(dun)構(gou)(gou)(gou)隧(sui)(sui)(sui)(sui)道管(guan)片(pian)(pian)(pian)(pian)連接(jie)件(jian)。

        因為(wei)不同(tong)的(de)(de)(de)管(guan)(guan)(guan)片(pian)(pian)(pian)尺寸(cun)大小也不一樣，盾構機的(de)(de)(de)直徑的(de)(de)(de)尺寸(cun)也不一樣、隧道中管(guan)(guan)(guan)片(pian)(pian)(pian)的(de)(de)(de)位置也不一樣，所以盾構管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓的(de)(de)(de)設計也不盡相(xiang)同(tong)。現在關于盾構管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓的(de)(de)(de)設計，國內外的(de)(de)(de)標準(zhun)還(huan)沒(mei)有(you)統一。但是我(wo)公司具有(you)多年生產(chan)經營(ying)，我(wo)們把盾構管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓分為(wei)以下幾(ji)類：淺埋(mai)式縱向(xiang)管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓、雙頭(tou)(tou)直型管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓、六(liu)角頭(tou)(tou)弧(hu)形管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓、六(liu)角頭(tou)(tou)帶(dai)法(fa)蘭(lan)面圓(yuan)弧(hu)螺(luo)(luo)栓管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓、雙頭(tou)(tou)弧(hu)形管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓、六(liu)角頭(tou)(tou)圓(yuan)弧(hu)螺(luo)(luo)紋管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓（另一個名稱是斜螺(luo)(luo)栓，又因為(wei)它的(de)(de)(de)螺(luo)(luo)紋很特殊，所以又叫做T型螺(luo)(luo)栓）、角頭(tou)(tou)直型管(guan)(guan)(guan)片(pian)(pian)(pian)螺(luo)(luo)栓。
