它(ta)能穿越公路(lu)、鐵路(lu)、橋(qiao)梁、高山、河流、海峽和(he)地面任何建筑物。采用(yong)該(gai)技(ji)術(shu)施工(gong)，能節約一大筆(bi)拆費用(yong)、減少(shao)對(dui)環(huan)境污(wu)染和(he)道(dao)路(lu)的(de)堵(du)塞，具有顯著(zhu)的(de)經(jing)(jing)濟效(xiao)益和(he)社會(hui)效(xiao)益。它(ta)的(de)技(ji)術(shu)要(yao)點在(zai)于(yu)糾正管(guan)(guan)子在(zai)地下延伸(shen)的(de)偏差。特別適用(yong)于(yu)大中型管(guan)(guan)徑的(de)非開挖(wa)鋪設(she)。具有經(jing)(jing)濟、，保(bao)護環(huan)境的(de)綜(zong)合功能。經(jing)(jing)過多年(nian)的(de)發展，頂(ding)管(guan)(guan)技(ji)術(shu)在(zai)我(wo)國已(yi)得到(dao)大量地實際工(gong)程應(ying)用(yong)，且保(bao)持著(zhu)高速的(de)增長勢頭，無論在(zai)技(ji)術(shu)上、頂(ding)管(guan)(guan)設(she)備還是施工(gong)工(gong)藝上取得了很大的(de)進步，在(zai)某些方面甚至(zhi)已(yi)達(da)到(dao)了水(shui)平(ping)。

經(jing)過(guo)多(duo)年的發(fa)展，頂(ding)管技術(shu)在我國已得(de)到大量地實(shi)際工(gong)(gong)程(cheng)應(ying)用，且保持(chi)著高速的增長(chang)勢(shi)頭(tou)，無(wu)論在技術(shu)上、頂(ding)管設備還(huan)是施(shi)工(gong)(gong)工(gong)(gong)藝上取得(de)了(le)很大的進步，在某些方面甚至(zhi)已達到了(le)水(shui)(shui)平。根據地質報告，并結合的施(shi)工(gong)(gong)經(jing)驗(yan)，頂(ding)管機頭(tou)決定(ding)采用氣(qi)壓(ya)平衡網格（水(shui)(shui)沖）式機頭(tou)進行施(shi)工(gong)(gong)。該機頭(tou)在頂(ding)進過(guo)程(cheng)中，通過(guo)氣(qi)壓(ya)平衡正面土壓(ya)穩(wen)定(ding)機頭(tou)，減少外部土體對周圍(wei)地面的影響。由于(yu)非開挖(wa)(wa)的優勢(shi)逐(zhu)漸被人們認同，非開挖(wa)(wa)技術(shu)日趨成熟，非開挖(wa)(wa)施(shi)工(gong)(gong)成本逐(zhu)年降低，所以非開挖(wa)(wa)的應(ying)用在逐(zhu)年增長(chang)。

經過多年的(de)(de)發(fa)展，頂管(guan)(guan)技術在我國已得到(dao)大量地(di)實際工(gong)(gong)程應用，且保持著高速的(de)(de)增長勢頭，無論在技術上(shang)、頂管(guan)(guan)設備還是施(shi)(shi)(shi)工(gong)(gong)工(gong)(gong)藝上(shang)取得了很大的(de)(de)進步(bu)，在某些方(fang)面(mian)甚(shen)至已達到(dao)了水平。頂管(guan)(guan)施(shi)(shi)(shi)工(gong)(gong)借助于主(zhu)頂油(you)缸及管(guan)(guan)道(dao)間中(zhong)繼間等的(de)(de)推力，把工(gong)(gong)具管(guan)(guan)或掘進機從工(gong)(gong)作(zuo)(zuo)井內穿過土層(ceng)一(yi)直推到(dao)接收井內吊起。與(yu)此(ci)同時，頂管(guan)(guan)非(fei)開(kai)挖施(shi)(shi)(shi)工(gong)(gong)價格，也就把緊隨工(gong)(gong)具管(guan)(guan)或掘進機后的(de)(de)管(guan)(guan)道(dao)埋設在兩井之(zhi)間，以(yi)期(qi)實現非(fei)開(kai)挖敷(fu)設地(di)下(xia)管(guan)(guan)道(dao)的(de)(de)施(shi)(shi)(shi)工(gong)(gong)方(fang)法。非(fei)開(kai)挖具有(you)環保宜居等競爭優勢。一(yi)個城市的(de)(de)開(kai)挖量超過一(yi)定(ding)比例，必然影響(xiang)交通和(he)市民(min)正(zheng)常生(sheng)活(huo)。而非(fei)開(kai)挖施(shi)(shi)(shi)工(gong)(gong)不阻礙交通、不污(wu)染(ran)環境、不破壞植被、不影響(xiang)周邊建(jian)筑物、不影響(xiang)居民(min)的(de)(de)一(yi)切(qie)正(zheng)常生(sheng)活(huo)和(he)工(gong)(gong)作(zuo)(zuo)秩(zhi)序。
