什么是頂(ding)管非開挖施工？

非開(kai)(kai)(kai)挖(wa)(wa)技(ji)術(shu)是才開(kai)(kai)(kai)始(shi)頻繁使用的一個(ge)術(shu)語，它涉及(ji)的是利用少開(kai)(kai)(kai)挖(wa)(wa)，即工作(zuo)井(jing)與接收井(jing)要(yao)開(kai)(kai)(kai)挖(wa)(wa)，以及(ji)不開(kai)(kai)(kai)挖(wa)(wa)，即管(guan)(guan)(guan)(guan)道不開(kai)(kai)(kai)挖(wa)(wa)技(ji)術(shu)來進(jin)行地(di)(di)下管(guan)(guan)(guan)(guan)線的鋪設或更換，頂管(guan)(guan)(guan)(guan)直徑DN800—4500。通過(guo)工作(zuo)井(jing)把要(yao)頂進(jin)的管(guan)(guan)(guan)(guan)子頂入接收井(jing)內，一個(ge)工作(zuo)井(jing)內的管(guan)(guan)(guan)(guan)子可在地(di)(di)下穿(chuan)行1500米(mi)以上，并且還能曲線穿(chuan)行，以繞開(kai)(kai)(kai)一些地(di)(di)下管(guan)(guan)(guan)(guan)線或障(zhang)礙物。?非開(kai)(kai)(kai)挖(wa)(wa)

非開(kai)挖的(de)技術(shu)要點在(zai)于糾正(zheng)管(guan)子在(zai)地下延伸(shen)的(de)偏差(cha)。特別適(shi)用于大中型管(guan)徑的(de)非開(kai)挖鋪設(she)。具有(you)經(jing)濟、，保護環境的(de)綜(zong)合功(gong)能。非開(kai)挖的(de)優點是：不(bu)(bu)開(kai)挖地面；不(bu)(bu)拆遷，不(bu)(bu)破壞地面建(jian)筑物；不(bu)(bu)破壞環境；不(bu)(bu)影(ying)響管(guan)道的(de)段差(cha)變(bian)形；省時、安全，綜(zong)合造價低(di)。

頂(ding)管(guan)(guan)(guan)在兩者之(zhi)間停止施(shi)工頂(ding)管(guan)(guan)(guan)頂(ding)管(guan)(guan)(guan)是管(guan)(guan)(guan)道施(shi)工的一(yi)(yi)種。非開(kai)挖(wa)是不開(kai)挖(wa)或者少(shao)開(kai)挖(wa)的一(yi)(yi)種管(guan)(guan)(guan)道鋪設(she)，其(qi)主(zhu)要(yao)應用(yong)頂(ding)管(guan)(guan)(guan)設(she)備產(chan)生(sheng)行進(jin)的力度(du)，去均衡(heng)管(guan)(guan)(guan)道與土(tu)(tu)體之(zhi)間產(chan)生(sheng)的摩擦力，是管(guan)(guan)(guan)道可以行進(jin)，同(tong)時還需(xu)求(qiu)將(jiang)管(guan)(guan)(guan)道占用(yong)的土(tu)(tu)體停止置換出來，終在土(tu)(tu)體中構成(cheng)一(yi)(yi)道管(guan)(guan)(guan)道。頂(ding)管(guan)(guan)(guan)的施(shi)工主(zhu)要(yao)依賴(lai)于頂(ding)管(guan)(guan)(guan)設(she)備，頂(ding)管(guan)(guan)(guan)設(she)備裝置調試與運轉關于管(guan)(guan)(guan)道成(cheng)型(xing)的質量至關重要(yao)。

小(xiao)編為您分享非開挖相關知識：非開挖技術準備工作

經(jing)過系統而(er)周詳(xiang)勘(kan)測(ce)與調查后，設計人員(yuan)應分析相(xiang)關資(zi)料信息得出施工現場的(de)一些施工技術(shu)(shu)條件，并根據勘(kan)察情(qing)況與技術(shu)(shu)分析確定合(he)理的(de)施工組織(zhi)設計。具體(ti)內(nei)容如下：

1.掌握(wo)施工現(xian)場地質情況，榆次非開挖，比如，含(han)水量(liang)、透水性質等。如果土層(ceng)中含(han)有(you)砂層(ceng)或巖層(ceng)，設計人員則需要進一(yi)步摸清(qing)砂層(ceng)及(ji)巖層(ceng)具體情況，然后(hou)選擇符合地質條件(jian)的(de)頂管施工技術；

2.分析(xi)與總結地下(xia)水位變化規律，并將其(qi)來源、水面高度及潮汐情(qing)況清楚描(miao)述出來；

3.掌握各種頂管施(shi)工技術的相關要點。

4.設(she)(she)(she)計施工線路與井位施工。經過詳細勘察與技術分析之后，設(she)(she)(she)計人員便(bian)可以此(ci)為依據設(she)(she)(she)計施工方(fang)式、線路及井位。然后，施工單位人員按照設(she)(she)(she)計圖上管道(dao)(dao)平(ping)面位置(zhi)，利(li)用(yong)測量儀器清楚標注出管道(dao)(dao)的具(ju)體位置(zhi)，非(fei)開(kai)挖管道(dao)(dao)施工項(xiang)目(mu)承包，即(ji)水平(ping)高度及作業方(fang)向(xiang)。

5.查(cha)看導(dao)向孔(kong)軌跡設計與(yu)(yu)施工(gong)(gong)是否合理，直接影響著管道(dao)施工(gong)(gong)的(de)精(jing)度，對(dui)管道(dao)施工(gong)(gong)成功(gong)與(yu)(yu)否有著至關重要的(de)影響。完成測(ce)量放線工(gong)(gong)作(zuo)后(hou)，非開(kai)挖管道(dao)施工(gong)(gong)技術，施工(gong)(gong)人員便可(ke)以在(zai)管道(dao)平(ping)面位置按照深度要求操作(zuo)定向鉆機作(zuo)業。

6.導向孔施(shi)工(gong)完(wan)成后，施(shi)工(gong)人員便(bian)(bian)可利用(yong)鉆擴(kuo)口對導向孔進(jin)行回(hui)擴(kuo)工(gong)序(xu)。進(jin)行回(hui)擴(kuo)工(gong)序(xu)時，非(fei)開挖工(gong)程承包，應始(shi)終保持適當的泥漿量，并(bing)根據實際需(xu)要合(he)理控(kong)制鉆進(jin)速度，以便(bian)(bian)排渣。回(hui)擴(kuo)工(gong)序(xu)一般分為幾次(ci)完(wan)成，并(bing)在(zai)后一次(ci)中采用(yong)擠擴(kuo)式(shi)鉆頭(tou)，以便(bian)(bian)使(shi)孔壁定(ding)型和穩定(ding)。

7.導向孔施(shi)工(gong)完成、孔壁具有一(yi)定(ding)強度后(hou)，則進(jin)入頂(ding)進(jin)施(shi)工(gong)工(gong)序。頂(ding)進(jin)施(shi)工(gong)過程中應(ying)嚴格(ge)注意以下內(nei)容：頂(ding)進(jin)時(shi)，頂(ding)鐵(tie)上不準站人；頂(ding)進(jin)就位后(hou)，應(ying)立即(ji)回復(fu)施(shi)工(gong)線(xian)路；頂(ding)進(jin)施(shi)工(gong)完成后(hou)，施(shi)工(gong)人員必須對管(guan)道線(xian)路進(jin)行(xing)(xing)修整(zheng)與鞏固，并進(jin)行(xing)(xing)相關實驗(yan)。

拉管施工要點：

1.擴孔(kong)完畢后(hou)，在管(guan)(guan)(guan)頭(tou)后(hou)接(jie)上回擴頭(tou)，管(guan)(guan)(guan)后(hou)接(jie)上分動器(qi)進(jin)行接(jie)管(guan)(guan)(guan)，單管(guan)(guan)(guan)拉(la)入(ru)孔(kong)中后(hou)，進(jin)行管(guan)(guan)(guan)道(dao)的焊接(jie)。焊縫檢(jian)驗合格后(hou)，繼續將管(guan)(guan)(guan)拉(la)入(ru)孔(kong)內，至管(guan)(guan)(guan)道(dao)鋪設(she)完成，卸下回擴頭(tou)、分動器(qi)、取出剩余鉆桿，即敷(fu)設(she)工程完成。

2.在拉管(guan)過程中，需嚴格控制(zhi)焊接和檢測時(shi)間(jian)，時(shi)間(jian)過長，會導(dao)致孔中泥漿水分滲漏、缺失及(ji)沉(chen)淀，加大回拖阻力，增(zeng)加拉管(guan)難度。施工時(shi)，操(cao)作人員要根據(ju)(ju)設備數據(ju)(ju)均(jun)勻平穩的牽引管(guan)道，切不可生(sheng)拉硬拽。
