? 管片螺栓的設計(ji)(ji)因(yin)(yin)為隧道管(guan)(guan)片(pian)(pian)(pian)(pian)的尺寸不(bu)同，盾(dun)構的直徑(jing)不(bu)同，管(guan)(guan)片(pian)(pian)(pian)(pian)在隧道中的位(wei)置不(bu)同，所(suo)以(yi)有多種設計(ji)(ji)，目(mu)前(qian)還沒有統一的設計(ji)(ji)標準(zhun)。因(yin)(yin)為我公司有多年緊固件(jian)生產(chan)經驗，我們一般把管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)分為以(yi)下幾類：雙頭弧(hu)形(xing)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)、淺埋式縱向管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)、六(liu)角(jiao)頭弧(hu)形(xing)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)、雙頭直形(xing)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)、六(liu)角(jiao)頭圓弧(hu)螺(luo)(luo)紋管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)、六(liu)角(jiao)頭直形(xing)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)、六(liu)角(jiao)頭帶法(fa)蘭面圓弧(hu)管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)等，其中六(liu)角(jiao)頭圓弧(hu)螺(luo)(luo)紋管(guan)(guan)片(pian)(pian)(pian)(pian)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)又叫(jiao)做對角(jiao)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)，因(yin)(yin)為其特(te)殊的螺(luo)(luo)紋，還稱(cheng)為T型(xing)螺(luo)(luo)栓(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)(shuan)。
管片螺栓(shuan)還(huan)可(ke)以分為縱向(xiang)(xiang)管片螺栓(shuan)和環向(xiang)(xiang)管片螺栓(shuan)，有些設(she)計具有相同(tong)規格的(de)(de)縱向(xiang)(xiang)和環向(xiang)(xiang)，而有的(de)(de)設(she)計中(zhong)縱向(xiang)(xiang)和環向(xiang)(xiang)規格不(bu)同(tong)，強度等級也不(bu)同(tong)，一般情況下，縱向(xiang)(xiang)管片螺栓(shuan)要比(bi)環向(xiang)(xiang)管片螺栓(shuan)的(de)(de)長度短。
在(zai)(zai)隧(sui)(sui)道工程中(zhong)，當需要(yao)掘進的(de)時(shi)(shi)候就需要(yao)用到(dao)盾(dun)構機了(le)，土體的(de)切(qie)削和(he)(he)開挖、土碴(cha)的(de)運輸(shu)、隧(sui)(sui)道襯砌(qi)拼(pin)裝都需要(yao)用到(dao)這種盾(dun)構機。當利用盾(dun)構機進行隧(sui)(sui)道襯砌(qi)時(shi)(shi)，盾(dun)構機通(tong)常是由多個管(guan)片(pian)(pian)(pian)(pian)組成的(de)，通(tong)過管(guan)片(pian)(pian)(pian)(pian)螺(luo)栓(shuan)的(de)連(lian)接(jie)緊(jin)固，這些管(guan)片(pian)(pian)(pian)(pian)形(xing)(xing)成圓柱形(xing)(xing)管(guan)道，這是管(guan)道的(de)墻(qiang)體就是管(guan)片(pian)(pian)(pian)(pian)了(le)，設(she)計成直線或圓弧(hu)的(de)緊(jin)固件就是管(guan)片(pian)(pian)(pian)(pian)螺(luo)栓(shuan)，管(guan)片(pian)(pian)(pian)(pian)螺(luo)栓(shuan)可以分為縱(zong)向(xiang)管(guan)片(pian)(pian)(pian)(pian)螺(luo)栓(shuan)和(he)(he)環向(xiang)管(guan)片(pian)(pian)(pian)(pian)螺(luo)栓(shuan)，有(you)些設(she)計具有(you)相(xiang)同(tong)規(gui)格(ge)的(de)縱(zong)向(xiang)和(he)(he)環向(xiang)，而有(you)的(de)設(she)計中(zhong)縱(zong)向(xiang)和(he)(he)環向(xiang)規(gui)格(ge)不(bu)同(tong)，強度(du)等級(ji)也(ye)不(bu)同(tong)，一般情況(kuang)下(xia)，縱(zong)向(xiang)管(guan)片(pian)(pian)(pian)(pian)螺(luo)栓(shuan)要(yao)比環向(xiang)管(guan)片(pian)(pian)(pian)(pian)螺(luo)栓(shuan)的(de)長(chang)度(du)短(duan)。在(zai)(zai)隧(sui)(sui)道挖進過程中(zhong)，可以很(hen)好地(di)控制地(di)面下(xia)降(jiang)，從而減少了(le)對建筑物又不(bu)好的(de)影響(xiang)，而且在(zai)(zai)水下(xia)挖掘時(shi)(shi)還不(bu)影響(xiang)水面交通(tong)。
