頂(ding)(ding)管(guan)施工(gong)(gong)(gong)就是(shi)(shi)非(fei)(fei)開(kai)(kai)(kai)挖(wa)施工(gong)(gong)(gong)方法(fa)，非(fei)(fei)開(kai)(kai)(kai)挖(wa)定向(xiang)鉆(zhan)施工(gong)(gong)(gong)，是(shi)(shi)一種不(bu)開(kai)(kai)(kai)挖(wa)或者少開(kai)(kai)(kai)挖(wa)的(de)管(guan)道(dao)(dao)埋(mai)設施工(gong)(gong)(gong)技(ji)(ji)術。頂(ding)(ding)管(guan)法(fa)施工(gong)(gong)(gong)就是(shi)(shi)在工(gong)(gong)(gong)作坑(keng)內借助(zhu)于頂(ding)(ding)進設備(bei)產生的(de)頂(ding)(ding)力(li)，克(ke)服管(guan)道(dao)(dao)與周圍(wei)土(tu)(tu)壤的(de)摩擦(ca)力(li)，將管(guan)道(dao)(dao)按(an)設計的(de)坡度頂(ding)(ding)入土(tu)(tu)中(zhong)，并(bing)將土(tu)(tu)方運走。地(di)下穿越是(shi)(shi)社會發(fa)展的(de)必然(ran)要(yao)求。無論是(shi)(shi)各行業部(bu)門規劃(hua)不(bu)到位，協調不(bu)好，還(huan)是(shi)(shi)基建發(fa)展需要(yao)，新(xin)的(de)地(di)下設施總在不(bu)斷增(zeng)加(jia)，這時要(yao)么開(kai)(kai)(kai)挖(wa)，要(yao)么非(fei)(fei)開(kai)(kai)(kai)挖(wa)，必然(ran)選擇其一。非(fei)(fei)開(kai)(kai)(kai)挖(wa)工(gong)(gong)(gong)程技(ji)(ji)術解決了管(guan)道(dao)(dao)埋(mai)設施工(gong)(gong)(gong)中(zhong)對城市建筑(zhu)物的(de)破壞(huai)和道(dao)(dao)路交通的(de)堵塞等難(nan)題，在穩定土(tu)(tu)層和環(huan)境(jing)保護方面凸(tu)顯其優勢(shi)。

由于地質強度不(bu)(bu)(bu)同(tong)，需(xu)選用不(bu)(bu)(bu)同(tong)的(de)(de)(de)機頭(tou)。強度大巖層，需(xu)選用具有(you)(you)破巖機頭(tou)；普(pu)通土質，可以(yi)選用泥(ni)水(shui)均衡(heng)頂(ding)管(guan)(guan)機械進行施(shi)工即可。采用通風裝置(zhi)予以(yi)解決。前探查地下管(guan)(guan)線盡管(guan)(guan)的(de)(de)(de)頂(ding)管(guan)(guan)設備具有(you)(you)在施(shi)工時探查前進路線不(bu)(bu)(bu)遠距(ju)離管(guan)(guan)線的(de)(de)(de)能力，確(que)保(bao)公眾正常生(sheng)活仍有(you)(you)必要。頂(ding)管(guan)(guan)施(shi)工有(you)(you)利于文明施(shi)工。泥(ni)水(shui)均衡(heng)法(fa)施(shi)工防止了泥(ni)水(shui)橫(heng)溢和(he)稀(xi)泥(ni)亂堆放的(de)(de)(de)不(bu)(bu)(bu)良現象，確(que)保(bao)自然環(huan)境(jing)不(bu)(bu)(bu)受凈(jing)化。安全系數高。頂(ding)管(guan)(guan)辦法(fa)是(shi)全自動搖控，不(bu)(bu)(bu)需(xu)工人(ren)在管(guan)(guan)道內任務。

采用4臺200噸/臺千(qian)(qian)斤(jin)頂(ding)作(zuo)為主(zhu)頂(ding)，千(qian)(qian)斤(jin)頂(ding)行程為1.4米。千(qian)(qian)斤(jin)頂(ding)動力由油(you)泵提供。千(qian)(qian)斤(jin)頂(ding)后(hou)端用道木和分(fen)(fen)壓環將(jiang)反力均勻作(zuo)用于工(gong)(gong)作(zuo)井，前(qian)端頂(ding)進(jin)分(fen)(fen)壓環，頂(ding)鐵(tie)將(jiang)頂(ding)力傳(chuan)至管(guan)節。非(fei)開(kai)(kai)挖(wa)(wa)工(gong)(gong)程技術了管(guan)道埋(mai)設(she)施(shi)(shi)工(gong)(gong)中(zhong)對城市建筑物的(de)(de)(de)(de)破壞和道路交通的(de)(de)(de)(de)堵塞等難題(ti)，在(zai)穩(wen)定土層和環境保護方面凸顯(xian)其優(you)勢。頂(ding)管(guan)施(shi)(shi)工(gong)(gong)就(jiu)是(shi)非(fei)開(kai)(kai)挖(wa)(wa)施(shi)(shi)工(gong)(gong)方法，是(shi)一種不開(kai)(kai)挖(wa)(wa)或者少開(kai)(kai)挖(wa)(wa)的(de)(de)(de)(de)管(guan)道埋(mai)設(she)施(shi)(shi)工(gong)(gong)技術。頂(ding)管(guan)法施(shi)(shi)工(gong)(gong)就(jiu)是(shi)在(zai)工(gong)(gong)作(zuo)坑內借助于頂(ding)進(jin)設(she)備產生的(de)(de)(de)(de)頂(ding)力，克服管(guan)道與周圍土壤的(de)(de)(de)(de)摩擦力，將(jiang)管(guan)道按設(she)計的(de)(de)(de)(de)坡度頂(ding)入土中(zhong)，并(bing)將(jiang)土方運走。
