管片(pian)螺絲

襯砌(qi)(qi)(qi)結構和(he)形(xing)式都(dou)會選擇管片螺絲。盾構隧(sui)道襯砌(qi)(qi)(qi)有三種類型(xing):預(yu)制襯砌(qi)(qi)(qi)、擠壓(ya)混凝土整(zheng)體襯砌(qi)(qi)(qi)、雙層襯砌(qi)(qi)(qi)。預(yu)制襯砌(qi)(qi)(qi)里(li)是工廠預(yu)制件(又叫做(zuo)管片),組裝在盾構的尾部。雙層襯砌(qi)(qi)(qi)...

        襯(chen)(chen)(chen)砌(qi)(qi)(qi)結構和形式都會(hui)選(xuan)擇管(guan)片(pian)螺絲。盾(dun)(dun)構隧(sui)道(dao)襯(chen)(chen)(chen)砌(qi)(qi)(qi)有三種類型:預(yu)制(zhi)(zhi)襯(chen)(chen)(chen)砌(qi)(qi)(qi)、擠壓混凝(ning)(ning)土(tu)整體襯(chen)(chen)(chen)砌(qi)(qi)(qi)、雙層(ceng)襯(chen)(chen)(chen)砌(qi)(qi)(qi)。預(yu)制(zhi)(zhi)襯(chen)(chen)(chen)砌(qi)(qi)(qi)里(li)是(shi)工廠預(yu)制(zhi)(zhi)件(jian)(又(you)叫做管(guan)片(pian)),組裝(zhuang)在(zai)(zai)盾(dun)(dun)構的尾部(bu)。雙層(ceng)襯(chen)(chen)(chen)砌(qi)(qi)(qi)能夠避(bi)免隧(sui)道(dao)有襯(chen)(chen)(chen)砌(qi)(qi)(qi)腐蝕和滲水的情況,糾正隧(sui)道(dao)施(shi)工錯誤,降低噪音和振動,還(huan)可以(yi)作(zuo)為內部(bu)的裝(zhuang)飾,在(zai)(zai)預(yu)制(zhi)(zhi)襯(chen)(chen)(chen)砌(qi)(qi)(qi)內部(bu)制(zhi)(zhi)作(zuo)一層(ceng)鋼筋(jin)混凝(ning)(ning)土(tu)襯(chen)(chen)(chen)砌(qi)(qi)(qi)或者整體混凝(ning)(ning)土(tu)。ECL是(shi)在(zai)(zai)盾(dun)(dun)構推(tui)進過程中,用(yong)一套襯(chen)(chen)(chen)砌(qi)(qi)(qi)施(shi)工設備在(zai)(zai)盾(dun)(dun)構尾部(bu)同步(bu)澆筑的鋼筋(jin)混凝(ning)(ning)土(tu)整體襯(chen)(chen)(chen)砌(qi)(qi)(qi)或者混凝(ning)(ning)土(tu)。

        盾構(gou)掘進(jin)(jin)(jin)機在掘進(jin)(jin)(jin)過程中需要把(ba)(ba)管(guan)(guan)片(pian)(pian)連(lian)(lian)(lian)接(jie)(jie)在一起(qi),把(ba)(ba)管(guan)(guan)片(pian)(pian)進(jin)(jin)(jin)行連(lian)(lian)(lian)接(jie)(jie)和緊固,管(guan)(guan)片(pian)(pian)螺絲就是對管(guan)(guan)片(pian)(pian)連(lian)(lian)(lian)接(jie)(jie)和固定的(de)(de)一種緊固件(jian)。有了管(guan)(guan)片(pian)(pian)螺絲的(de)(de)連(lian)(lian)(lian)接(jie)(jie),多個呈(cheng)現拱形的(de)(de)管(guan)(guan)片(pian)(pian)連(lian)(lian)(lian)接(jie)(jie)在一起(qi),形成一個圓,這個圓能夠把(ba)(ba)隧(sui)道(dao)的(de)(de)表面支(zhi)撐起(qi)來,它是專用于隧(sui)道(dao)的(de)(de)緊固件(jian),又叫做連(lian)(lian)(lian)接(jie)(jie)件(jian)。
