施(shi)(shi)(shi)工(gong)(gong)設備(bei)和(he)施(shi)(shi)(shi)工(gong)(gong)人(ren)員(yuan)的(de)(de)(de)素(su)質是保(bao)證非開挖工(gong)(gong)程(cheng)(cheng)質量的(de)(de)(de)另一要(yao)求。非開挖施(shi)(shi)(shi)工(gong)(gong)設備(bei)的(de)(de)(de)更新(xin)換代十分(fen)頻繁，施(shi)(shi)(shi)工(gong)(gong)廠家(jia)要(yao)保(bao)證施(shi)(shi)(shi)工(gong)(gong)所(suo)(suo)用設備(bei)為(wei)行業 設備(bei)，落后(hou)設備(bei)雖然(ran)也(ye)能完成(cheng)(cheng)工(gong)(gong)程(cheng)(cheng)，但工(gong)(gong)程(cheng)(cheng)質量和(he)效(xiao)率有待提高。在(zai)城市(shi)建(jian)設中(zhong)非開挖技(ji)術(shu)已(yi)經成(cheng)(cheng)為(wei)了主(zhu)流，非開挖施(shi)(shi)(shi)工(gong)(gong)工(gong)(gong)程(cheng)(cheng)價(jia)格，但是在(zai)實施(shi)(shi)(shi)非開挖工(gong)(gong)程(cheng)(cheng)時一定要(yao)注意(yi)微小的(de)(de)(de)細節，避(bi)免出(chu)現一些(xie)的(de)(de)(de)意(yi)外。這樣不僅會耽誤工(gong)(gong)程(cheng)(cheng)的(de)(de)(de)進程(cheng)(cheng)，造成(cheng)(cheng)成(cheng)(cheng)本，而且還會給對(dui)人(ren)員(yuan)安全造成(cheng)(cheng)傷害，因此一定要(yao)注意(yi)安全。穿(chuan)越建(jian)筑時對(dui)基(ji)(ji)礎的(de)(de)(de)探(tan)查(cha)頂(ding)管在(zai)建(jian)筑物基(ji)(ji)礎下施(shi)(shi)(shi)工(gong)(gong)時，需要(yao)明確施(shi)(shi)(shi)工(gong)(gong)施(shi)(shi)(shi)工(gong)(gong)路(lu)線上所(suo)(suo)遇到(dao)的(de)(de)(de)基(ji)(ji)礎類型(xing)，對(dui)于部(bu)分(fen)基(ji)(ji)礎頂(ding)管頂(ding)進前可采取托換、加固措施(shi)(shi)(shi)。

頂(ding)管(guan)(guan)(guan)施(shi)工是(shi)(shi)繼(ji)盾構施(shi)工之后而發(fa)展起來(lai)(lai)的(de)(de)(de)一種(zhong)地下(xia)(xia)管(guan)(guan)(guan)道(dao)施(shi)工方(fang)法，它不(bu)需要開(kai)挖面層，并且能夠穿(chuan)越公路、鐵道(dao)、河(he)川、地面建筑物(wu)、地下(xia)(xia)構筑物(wu)以(yi)及(ji)各(ge)種(zhong)地下(xia)(xia)管(guan)(guan)(guan)線等(deng)。非開(kai)挖技(ji)術之所以(yi)受到(dao)越來(lai)(lai)越多的(de)(de)(de)應用(yong)和重視，既有(you)(you)其固有(you)(you)的(de)(de)(de)技(ji)術優勢，也有(you)(you)社會(hui)發(fa)展帶(dai)來(lai)(lai)的(de)(de)(de)巨大渴求，主(zhu)要表現在：地下(xia)(xia)穿(chuan)越是(shi)(shi)社會(hui)發(fa)展的(de)(de)(de)必然要求。頂(ding)管(guan)(guan)(guan)施(shi)工借助于主(zhu)頂(ding)油缸及(ji)管(guan)(guan)(guan)道(dao)間中(zhong)繼(ji)間等(deng)的(de)(de)(de)推力(li)，把工具(ju)管(guan)(guan)(guan)或掘(jue)進機從工作井內穿(chuan)過土(tu)層一直推到(dao)接收井內吊(diao)起。與此同時，也就把緊隨工具(ju)管(guan)(guan)(guan)或掘(jue)進機后的(de)(de)(de)管(guan)(guan)(guan)道(dao)埋設在兩井之間，以(yi)期(qi)實現非開(kai)挖敷設地下(xia)(xia)管(guan)(guan)(guan)道(dao)的(de)(de)(de)施(shi)工方(fang)法。

前殼體(ti)與(yu)前接管(guan)(guan)(guan)連(lian)接，后(hou)殼體(ti)與(yu)后(hou)接管(guan)(guan)(guan)連(lian)接，前后(hou)殼體(ti)間為(wei)承插式連(lian)接，兩(liang)者間依(yi)靠橡膠止水(shui)(shui)帶(dai)密(mi)封，防止管(guan)(guan)(guan)道(dao)外水(shui)(shui)土(tu)和漿液倒流入管(guan)(guan)(guan)道(dao)內。頂管(guan)(guan)(guan)施(shi)工(gong)(gong)突出的特點就是(shi)適應性問(wen)題(ti)。針對不同的地質情況(kuang)、施(shi)工(gong)(gong)條件(jian)和設(she)計要求，選用與(yu)之(zhi)適應的頂管(guan)(guan)(guan)施(shi)工(gong)(gong)方式，如(ru)何正確地選擇(ze)頂管(guan)(guan)(guan)機和配(pei)套(tao)輔助設(she)備(bei)，對于頂管(guan)(guan)(guan)施(shi)工(gong)(gong)來說(shuo)將是(shi)非常關鍵的。這(zhe)種技術的優點是(shi)：不開挖地面；不拆，不破壞地面建筑(zhu)物；不破壞環境；不影(ying)響管(guan)(guan)(guan)道(dao)的段(duan)差(cha)變形；省時、、安全，綜合(he)造價低。
