我國人均管道的(de)(de)占有量遠(yuan)低于(yu)西方發達(da)國家， 利用(yong)非開(kai)挖水平定向鉆機的(de)(de)非開(kai)挖技術之(zhi)所(suo)以受到(dao)越來越多的(de)(de)應(ying)用(yong)和(he)重視(shi)，既有其固(gu)有的(de)(de)技術優勢，也有社會(hui)發展帶來的(de)(de)巨大渴(ke)求。采用(yong)4臺200噸/臺千(qian)斤(jin)頂(ding)作(zuo)為(wei)主頂(ding)，千(qian)斤(jin)頂(ding)行程為(wei)1.4米。千(qian)斤(jin)頂(ding)動(dong)力(li)由油泵提供。千(qian)斤(jin)頂(ding)后端用(yong)道木(mu)和(he)分(fen)壓(ya)環將反(fan)力(li)均勻作(zuo)用(yong)于(yu)工作(zuo)井，前端頂(ding)進分(fen)壓(ya)環，頂(ding)鐵將頂(ding)力(li)傳至管節。前殼(ke)體與(yu)前接(jie)(jie)管連接(jie)(jie)，后殼(ke)體與(yu)后接(jie)(jie)管連接(jie)(jie)，前后殼(ke)體間(jian)為(wei)承插式連接(jie)(jie)，兩(liang)者間(jian)依(yi)靠橡膠止(zhi)(zhi)水帶密封，防止(zhi)(zhi)管道外水土和(he)漿液倒(dao)流(liu)入管道內。

非(fei)開(kai)挖(wa)(wa)具有環保宜居(ju)等競爭優勢。一(yi)(yi)個(ge)城(cheng)市(shi)的(de)(de)(de)開(kai)挖(wa)(wa)量超過(guo)一(yi)(yi)定(ding)比例，必然影(ying)響交通和(he)市(shi)民正常生活。而非(fei)開(kai)挖(wa)(wa)施工(gong)(gong)不(bu)(bu)阻礙交通、不(bu)(bu)污染環境、不(bu)(bu)破壞植被、不(bu)(bu)影(ying)響周邊建筑物、不(bu)(bu)影(ying)響居(ju)民的(de)(de)(de)一(yi)(yi)切正常生活和(he)工(gong)(gong)作(zuo)秩序(xu)。經過(guo)多(duo)年的(de)(de)(de)發(fa)展，頂(ding)管技(ji)術在我國已(yi)(yi)得到大量地(di)(di)實(shi)際工(gong)(gong)程應用，且保持(chi)著(zhu)高速的(de)(de)(de)增長(chang)勢頭，無(wu)論在技(ji)術上、頂(ding)管設(she)(she)備還是(shi)施工(gong)(gong)工(gong)(gong)藝上取得了(le)很大的(de)(de)(de)進步，在某些方(fang)面(mian)甚(shen)至已(yi)(yi)達(da)到了(le)水(shui)平。地(di)(di)下(xia)管線是(shi)城(cheng)市(shi)基礎(chu)設(she)(she)施的(de)(de)(de)重(zhong)要組成部分，電纜管、上下(xia)水(shui)管網、熱(re)力(動力)管道(dao)同地(di)(di)下(xia)鐵(tie)道(dao)一(yi)(yi)起，被稱為城(cheng)市(shi)的(de)(de)(de)生命線，隨著(zhu)社會的(de)(de)(de)發(fa)展，地(di)(di)下(xia)管線的(de)(de)(de)長(chang)度持(chi)續增加。

該技術在我(wo)國沿(yan)海(hai)經濟發達地區(qu)廣泛用于城(cheng)市(shi)(shi)地下(xia)(xia)給(gei)排(pai)水(shui)管(guan)(guan)(guan)道(dao)(dao)、石(shi)油管(guan)(guan)(guan)道(dao)(dao)、通(tong)訊電纜等(deng)各種管(guan)(guan)(guan)道(dao)(dao)的(de)(de)非(fei)(fei)開(kai)挖(wa)鋪設。頂(ding)(ding)管(guan)(guan)(guan)施(shi)工(gong)(gong)(gong)(gong)借助于主(zhu)頂(ding)(ding)油缸及(ji)管(guan)(guan)(guan)道(dao)(dao)間中繼間等(deng)的(de)(de)推力，把工(gong)(gong)(gong)(gong)具管(guan)(guan)(guan)或掘(jue)進(jin)機從工(gong)(gong)(gong)(gong)作井(jing)內穿過(guo)土層(ceng)一(yi)直推到接收井(jing)內吊起。與此同(tong)時(shi)，非(fei)(fei)開(kai)挖(wa)施(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)程價格，也就把緊隨工(gong)(gong)(gong)(gong)具管(guan)(guan)(guan)或掘(jue)進(jin)機后的(de)(de)管(guan)(guan)(guan)道(dao)(dao)埋設在兩井(jing)之間，以期實現(xian)非(fei)(fei)開(kai)挖(wa)敷設地下(xia)(xia)管(guan)(guan)(guan)道(dao)(dao)的(de)(de)施(shi)工(gong)(gong)(gong)(gong)方法。地下(xia)(xia)管(guan)(guan)(guan)線(xian)是城(cheng)市(shi)(shi)基礎設施(shi)的(de)(de)重要組成部分，電纜管(guan)(guan)(guan)、上下(xia)(xia)水(shui)管(guan)(guan)(guan)網、熱力(動力)管(guan)(guan)(guan)道(dao)(dao)同(tong)地下(xia)(xia)鐵(tie)道(dao)(dao)一(yi)起，被稱為城(cheng)市(shi)(shi)的(de)(de)生(sheng)(sheng)命線(xian)，隨著社會的(de)(de)發展，地下(xia)(xia)管(guan)(guan)(guan)線(xian)的(de)(de)長度持(chi)續增加，非(fei)(fei)開(kai)挖(wa)市(shi)(shi)場(chang)存(cun)在生(sheng)(sheng)長空間。
