長期以來，城(cheng)市(shi)建(jian)設(she)(she)過(guo)程中，城(cheng)市(shi)道路(lu)被(bei)頻(pin)繁開挖嚴重影響了(le)人民(min)的生活。一項非開挖施(shi)(shi)工(gong)(gong)技術(shu)——頂管(guan)(guan)施(shi)(shi)工(gong)(gong)技術(shu)，不需(xu)開挖地面(mian)，并且能夠穿越公路(lu)、鐵路(lu)、河道、湖泊、建(jian)筑物、以及各種地下管(guan)(guan)線等(deng)，解決了(le)市(shi)政施(shi)(shi)工(gong)(gong)難題，而且，頂管(guan)(guan)施(shi)(shi)工(gong)(gong)隨(sui)著城(cheng)市(shi)建(jian)設(she)(she)的發展(zhan)已越來越普(pu)及，已運用(yong)到給排水、煤氣、電力、通信等(deng)管(guan)(guan)道的施(shi)(shi)工(gong)(gong)。頂管(guan)(guan)法(fa)施(shi)(shi)工(gong)(gong)就是在(zai)工(gong)(gong)作(zuo)坑內(nei)借助于(yu)頂進(jin)設(she)(she)備產生的頂力，克(ke)服管(guan)(guan)道與周(zhou)圍土壤的摩擦力，將(jiang)管(guan)(guan)道按設(she)(she)計的坡度頂入土中，并將(jiang)土方(fang)運走(zou)。一節(jie)管(guan)(guan)子完成(cheng)頂入土層(ceng)之(zhi)后，再(zai)下第二節(jie)管(guan)(guan)子繼(ji)續頂進(jin)。其(qi)原理是借助于(yu)主頂油(you)缸及管(guan)(guan)道間(jian)、中繼(ji)間(jian)等(deng)推(tui)(tui)力，把工(gong)(gong)具(ju)(ju)管(guan)(guan)或掘進(jin)機從工(gong)(gong)作(zuo)坑內(nei)穿過(guo)土層(ceng)一直推(tui)(tui)進(jin)到接(jie)收坑內(nei)吊起。管(guan)(guan)道緊(jin)隨(sui)工(gong)(gong)具(ju)(ju)管(guan)(guan)或掘進(jin)機后，埋(mai)設(she)(she)在(zai)兩坑之(zhi)間(jian)。臨時水準點應(ying)設(she)(she)置在(zai)交通要道、挖填方(fang)范圍以外。福州(zhou)DN3200水泥(ni)頂管(guan)(guan)施(shi)(shi)工(gong)(gong)每(mei)米價格
