小(xiao)編為您分享非開挖頂管施工(gong)相關知(zhi)識(shi)：

管(guan)(guan)道頂(ding)(ding)(ding)(ding)管(guan)(guan)施(shi)工方(fang)案(an)區別于傳動的(de)開(kai)挖的(de)管(guan)(guan)道埋設施(shi)工技術，管(guan)(guan)道頂(ding)(ding)(ding)(ding)管(guan)(guan)施(shi)工是(shi)(shi)一(yi)種非(fei)開(kai)挖或(huo)者說(shuo)盡可能少開(kai)挖方(fang)法。簡單來(lai)說(shuo)，非(fei)開(kai)挖頂(ding)(ding)(ding)(ding)管(guan)(guan)施(shi)工多(duo)少錢，就是(shi)(shi)利用頂(ding)(ding)(ding)(ding)進設備(bei)產生的(de)頂(ding)(ding)(ding)(ding)力在工作(zuo)坑將管(guan)(guan)道頂(ding)(ding)(ding)(ding)入(ru)(ru)土中(zhong)，并將泥漿排到特定地點。完成(cheng)一(yi)節(jie)管(guan)(guan)子(zi)頂(ding)(ding)(ding)(ding)入(ru)(ru)土層之后，再放置(zhi)第二根管(guan)(guan)子(zi)，如此依次(ci)完成(cheng)，形(xing)成(cheng)目(mu)標管(guan)(guan)道。

其具體方(fang)案步驟如下：

1.準備階段：

提前進行施工準備，主要包括場地布置，支護(hu)措施，設備選(xuan)擇和頂進設備安裝等。

2.工作(zuo)井的洞口處理(li)

環管(guan)外(wai)經(jing)安裝(zhuang)止(zhi)水圈(主要由鋼制法蘭盤(pan)和(he)一(yi)片橡膠(jiao)盤(pan)墊組成)，用于(yu)阻止(zhi)頂進時產生的泥漿(jiang)從管(guan)外(wai)壁與土(tu)體間的縫隙流入(ru)工作井。然后將頂管(guan)機頭(tou)入(ru)洞(dong)。

3.頂進過過程

本過(guo)程分為(wei)初始頂(ding)進(jin)和(he)正(zheng)常(chang)頂(ding)進(jin)兩個階段，初始頂(ding)進(jin)主要注意觀(guan)察掘進(jin)機(ji)與工作(zuo)井內導軌(gui)的(de)接觸(chu)情況是否正(zheng)常(chang)，非開挖頂(ding)管施工報(bao)價，即使進(jin)行糾偏;正(zheng)常(chang)頂(ding)進(jin)時，為(wei)確(que)保掘進(jin)機(ji)的(de)泥水倉保持一(yi)定的(de)壓力，需控(kong)制好進(jin)、排(pai)泥水的(de)流量。

小編為您分(fen)享非(fei)開挖頂(ding)管施(shi)工相關知識：

要及(ji)(ji)時(shi)正確(que)的解(jie)決頂(ding)管(guan)工程(cheng)中的外力(li)不(bu)平衡因(yin)素，我們首先應(ying)(ying)找出原因(yin)，然后再找到解(jie)決辦(ban)法，在頂(ding)進(jin)過程(cheng)中應(ying)(ying)經常(chang)對管(guan)道的軸線進(jin)行觀測，非開挖頂(ding)管(guan)施(shi)工公(gong)司，發(fa)現偏差須及(ji)(ji)時(shi)采(cai)取(qu)措施(shi)糾正，技巧如下:

一(yi)(yi):推進(jin)的管(guan)線不可(ke)能在一(yi)(yi)定(ding)直線上;嚴(yan)格(ge)控制挖(wa)土(tu)時(shi)兩側均勻挖(wa)土(tu)，正常情況下不允許超挖(wa).

二:管(guan)道截面不可能垂直于(yu)管(guan)道軸線;發生偏差的(de)時候(hou)，不可急于(yu)求成否則會造成忽左忽右.

三:管節(jie)之間墊板的(de)壓縮性不(bu)完全(quan)一(yi)致(zhi)，利用(yong)(yong)挖土(tu)(tu)糾(jiu)(jiu)偏多挖土(tu)(tu)一(yi)側阻力(li)小(xiao)少挖土(tu)(tu)一(yi)側阻力(li)大利用(yong)(yong)土(tu)(tu)本(ben)身的(de)阻力(li)糾(jiu)(jiu)偏。

小編為您分享非開挖(wa)頂管施(shi)工(gong)相(xiang)關知識：

頂(ding)管(guan)和定(ding)向鉆是兩種完(wan)全不同的(de)(de)施工工藝，但很多人(ren)都很困惑，甚至包括非(fei)開挖行業的(de)(de)很多員(yuan)工。

頂管(guan)和定(ding)向鉆均為非開(kai)挖或少開(kai)挖施工工藝。

(1)頂管是什么？

顧名思(si)義，頂(ding)(ding)管(guan)就是(shi)用(yong)力(li)把管(guan)道(dao)(dao)往(wang)前推，然(ran)后(hou)說就是(shi)用(yong)頂(ding)(ding)進(jin)設備(bei)把管(guan)道(dao)(dao)一段(duan)一段(duan)的(de)往(wang)土里推。工(gong)(gong)(gong)人(ren)需要鉆進(jin)管(guan)道(dao)(dao)，原(yuan)平非開挖(wa)頂(ding)(ding)管(guan)施(shi)工(gong)(gong)(gong)，挖(wa)出來(lai)推。其原(yuan)理是(shi)利用(yong)頂(ding)(ding)進(jin)設備(bei)產(chan)生的(de)推力(li)克服管(guan)壁與土壤(rang)之間的(de)摩擦，然(ran)后(hou)配合(he)人(ren)工(gong)(gong)(gong)挖(wa)掘，終達到將多條管(guan)道(dao)(dao)頂(ding)(ding)入土壤(rang)的(de)目的(de)；

(2)定向鉆(zhan)是什么？

從水(shui)平定(ding)向(xiang)鉆(zhan)(zhan)的(de)名稱可(ke)以看(kan)出(chu)，必須有一個鉆(zhan)(zhan)頭，鉆(zhan)(zhan)頭的(de)鉆(zhan)(zhan)頭路線受(shou)到控制，即水(shui)平定(ding)向(xiang)鉆(zhan)(zhan)的(de)名稱可(ke)以實現定(ding)向(xiang)。整個施工過程可(ke)簡單總結為：定(ding)向(xiang)鉆(zhan)(zhan)頭向(xiang)前鉆(zhan)(zhan)孔，向(xiang)后(hou)擴孔，然(ran)后(hou)拖回管道，施工完成。
