頂(ding)(ding)管(guan)(guan)直徑DN800—4500。通過工(gong)作(zuo)井(jing)把要頂(ding)(ding)進的(de)管(guan)(guan)子頂(ding)(ding)入接(jie)收井(jing)內(nei)，一(yi)(yi)個工(gong)作(zuo)井(jing)內(nei)的(de)管(guan)(guan)子可在地(di)(di)下穿行(xing)(xing)1500米(mi)以上，并且還(huan)能曲線穿行(xing)(xing)，以繞開(kai)(kai)一(yi)(yi)些地(di)(di)下管(guan)(guan)線或(huo)障礙(ai)物。無論是各行(xing)(xing)業部門規劃不到位，管(guan)(guan)道非(fei)開(kai)(kai)挖施(shi)(shi)工(gong)施(shi)(shi)工(gong)公司(si)，協調不好，還(huan)是基建發展需要，新的(de)地(di)(di)下設施(shi)(shi)總(zong)在不斷增加，這(zhe)時要么開(kai)(kai)挖，要么非(fei)開(kai)(kai)挖，必然選擇其一(yi)(yi)。根據地(di)(di)質(zhi)報告，并結合的(de)施(shi)(shi)工(gong)經驗，頂(ding)(ding)管(guan)(guan)機(ji)(ji)頭(tou)決定(ding)采用(yong)氣壓平衡網(wang)格(ge)（水沖）式機(ji)(ji)頭(tou)進行(xing)(xing)施(shi)(shi)工(gong)。該機(ji)(ji)頭(tou)在頂(ding)(ding)進過程中，通過氣壓平衡正面土壓穩定(ding)機(ji)(ji)頭(tou)，減少外部土體對周圍(wei)地(di)(di)面的(de)影(ying)響。

采用4臺(tai)(tai)200噸/臺(tai)(tai)千斤(jin)頂(ding)(ding)(ding)作(zuo)為(wei)主頂(ding)(ding)(ding)，千斤(jin)頂(ding)(ding)(ding)行程(cheng)為(wei)1.4米。千斤(jin)頂(ding)(ding)(ding)動力(li)(li)(li)由油泵提供。千斤(jin)頂(ding)(ding)(ding)后(hou)端(duan)用道(dao)木和(he)分(fen)壓環(huan)將(jiang)(jiang)反力(li)(li)(li)均勻作(zuo)用于工(gong)(gong)作(zuo)井，前端(duan)頂(ding)(ding)(ding)進分(fen)壓環(huan)，頂(ding)(ding)(ding)鐵將(jiang)(jiang)頂(ding)(ding)(ding)力(li)(li)(li)傳至管(guan)節。非開挖(wa)(wa)工(gong)(gong)程(cheng)技(ji)術(shu)(shu)了管(guan)道(dao)埋設施(shi)(shi)工(gong)(gong)中對(dui)城(cheng)市(shi)建筑物的(de)破壞和(he)道(dao)路交通的(de)堵(du)塞等難題(ti)，在穩定(ding)土層和(he)環(huan)境保護方(fang)面凸顯(xian)其優勢。頂(ding)(ding)(ding)管(guan)施(shi)(shi)工(gong)(gong)就是非開挖(wa)(wa)施(shi)(shi)工(gong)(gong)方(fang)法(fa)，是一種(zhong)不(bu)開挖(wa)(wa)或者少開挖(wa)(wa)的(de)管(guan)道(dao)埋設施(shi)(shi)工(gong)(gong)技(ji)術(shu)(shu)。頂(ding)(ding)(ding)管(guan)法(fa)施(shi)(shi)工(gong)(gong)就是在工(gong)(gong)作(zuo)坑內(nei)借助于頂(ding)(ding)(ding)進設備(bei)產生的(de)頂(ding)(ding)(ding)力(li)(li)(li)，克服管(guan)道(dao)與周圍土壤(rang)的(de)摩擦力(li)(li)(li)，將(jiang)(jiang)管(guan)道(dao)按設計(ji)的(de)坡度頂(ding)(ding)(ding)入土中，并將(jiang)(jiang)土方(fang)運走。
