        盾(dun)(dun)(dun)構(gou)(gou)(gou)(gou)管(guan)(guan)(guan)(guan)(guan)片(pian)螺(luo)栓(shuan)(shuan)是一種特殊的緊固件，主要用在隧道(dao)(dao)工程中(zhong)，盾(dun)(dun)(dun)構(gou)(gou)(gou)(gou)掘(jue)進(jin)機掘(jue)進(jin)過程中(zhong)用來(lai)(lai)連(lian)接管(guan)(guan)(guan)(guan)(guan)片(pian)的。通過盾(dun)(dun)(dun)構(gou)(gou)(gou)(gou)管(guan)(guan)(guan)(guan)(guan)片(pian)螺(luo)栓(shuan)(shuan)的連(lian)接，幾個拱(gong)形的管(guan)(guan)(guan)(guan)(guan)片(pian)就可以(yi)連(lian)接成一個圓形來(lai)(lai)支撐起整個隧道(dao)(dao)表面，所以(yi)叫(jiao)(jiao)盾(dun)(dun)(dun)構(gou)(gou)(gou)(gou)管(guan)(guan)(guan)(guan)(guan)片(pian)螺(luo)栓(shuan)(shuan)，還可以(yi)叫(jiao)(jiao)管(guan)(guan)(guan)(guan)(guan)片(pian)連(lian)接器，由于盾(dun)(dun)(dun)構(gou)(gou)(gou)(gou)管(guan)(guan)(guan)(guan)(guan)片(pian)螺(luo)栓(shuan)(shuan)是專(zhuan)門用于盾(dun)(dun)(dun)構(gou)(gou)(gou)(gou)隧道(dao)(dao)的原因，所以(yi)又叫(jiao)(jiao)盾(dun)(dun)(dun)構(gou)(gou)(gou)(gou)隧道(dao)(dao)管(guan)(guan)(guan)(guan)(guan)片(pian)螺(luo)栓(shuan)(shuan)或盾(dun)(dun)(dun)構(gou)(gou)(gou)(gou)隧道(dao)(dao)管(guan)(guan)(guan)(guan)(guan)片(pian)連(lian)接件。

        因為(wei)不(bu)(bu)同的(de)管(guan)(guan)(guan)片(pian)(pian)尺(chi)寸(cun)大小也(ye)(ye)不(bu)(bu)一樣，盾(dun)構機的(de)直(zhi)徑的(de)尺(chi)寸(cun)也(ye)(ye)不(bu)(bu)一樣、隧道中管(guan)(guan)(guan)片(pian)(pian)的(de)位(wei)置(zhi)也(ye)(ye)不(bu)(bu)一樣，所以(yi)盾(dun)構管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)的(de)設(she)(she)計(ji)也(ye)(ye)不(bu)(bu)盡相同。現在關于盾(dun)構管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)的(de)設(she)(she)計(ji)，國內(nei)外的(de)標準還(huan)沒有(you)統一。但是(shi)我(wo)公司(si)具有(you)多年(nian)生產經營，我(wo)們把盾(dun)構管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)分為(wei)以(yi)下幾類(lei)：淺埋式縱向管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)、雙頭直(zhi)型(xing)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)、六角(jiao)頭弧形管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)、六角(jiao)頭帶法(fa)蘭(lan)面圓弧螺(luo)(luo)栓(shuan)(shuan)(shuan)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)、雙頭弧形管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)、六角(jiao)頭圓弧螺(luo)(luo)紋管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)（另一個名稱是(shi)斜螺(luo)(luo)栓(shuan)(shuan)(shuan)，又因為(wei)它的(de)螺(luo)(luo)紋很特殊(shu)，所以(yi)又叫做T型(xing)螺(luo)(luo)栓(shuan)(shuan)(shuan)）、角(jiao)頭直(zhi)型(xing)管(guan)(guan)(guan)片(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)。
