小編為您(nin)分享頂管施工相關(guan)知識：

頂管機頂進預備任務

1、頂(ding)管(guan)施工(gong)降水(shui)(shui)施工(gong)前仔細分析(xi)地質勘探報告，如有(you)地下水(shui)(shui)或濕(shi)土，應先確立合理的降水(shui)(shui)方案，做好施工(gong)防水(shui)(shui)任(ren)務，防止帶水(shui)(shui)頂(ding)進。依據地質報告，此處路基下不(bu)含(han)地下水(shui)(shui)，對(dui)施工(gong)頂(ding)進較為有(you)利。

2、頂(ding)(ding)管施工(gong)任(ren)務坑(keng)尺寸(cun)依(yi)據管長、頂(ding)(ding)鎬及(ji)頂(ding)(ding)進寬度(du)等確(que)定。坑(keng)底寬度(du)普通(tong)為(wei)管外徑(jing)加(jia)2.5～3m，本此(ci)頂(ding)(ding)進確(que)定為(wei)6米；長度(du)為(wei)管長加(jia)3～4m，依(yi)據頂(ding)(ding)進寬度(du)，確(que)定為(wei)30米。坑(keng)側壁(bi)應采用支撐擋土，嚴(yan)厲(li)避免塌方(fang)。后背(bei)依(yi)據頂(ding)(ding)力(li)大(da)小計算(suan)確(que)定，公路頂(ding)(ding)管施工(gong)，用鋼筋混凝土延續墻(qiang)作(zuo)后背(bei)，千斤頂(ding)(ding)后座(zuo)不允許直接作(zuo)用在(zai)后背(bei)墻(qiang)上，離石頂(ding)(ding)管施工(gong)，需(xu)鋪設槽鋼或工(gong)字鋼，以(yi)分散后背(bei)墻(qiang)頂(ding)(ding)力(li)。任(ren)務坑(keng)思索防水密封。

3、不(bu)含水的狀況下(xia)，依據矩(ju)形頂(ding)(ding)管(guan)機的頂(ding)(ding)進(jin)需求挖(wa)(wa)土(tu)(tu)(tu)避免挖(wa)(wa)土(tu)(tu)(tu)時可以先(xian)將管(guan)前上挖(wa)(wa)空(kong)，挖(wa)(wa)空(kong)深度(du)應(ying)(ying)視現場土(tu)(tu)(tu)質而(er)定。為避免工作面坍塌，每次掘進(jin)深度(du)不(bu)能(neng)超(chao)越0.3m，當管(guan)道中止頂(ding)(ding)進(jin)時，不(bu)在管(guan)前多(duo)挖(wa)(wa)超(chao)挖(wa)(wa) 當遇(yu)到砂或砂卵石等(deng)不(bu)波動土(tu)(tu)(tu)時，頂(ding)(ding)進(jin)的管(guan)前應(ying)(ying)先(xian)套鋼(gang)板護(hu)罩，再挖(wa)(wa)除(chu)鋼(gang)板護(hu)罩內的土(tu)(tu)(tu)，不(bu)允許在護(hu)罩前挖(wa)(wa)土(tu)(tu)(tu)。

頂(ding)管(guan)施工注意事項如下：

1. 千斤頂(ding)的著(zhu)力點，頂(ding)管(guan)隧道施工，著(zhu)力點一般位于管(guan)子總高的1/4到(dao)1/3的地方。

2. 頂(ding)(ding)進(jin)(jin)方(fang)(fang)(fang)(fang)向控制，管(guan)(guan)道(dao)的方(fang)(fang)(fang)(fang)向應用(yong)經緯儀(yi)校核，管(guan)(guan)子(zi)(zi)每頂(ding)(ding)30cm需(xu)用(yong)經緯儀(yi)校核一次，若管(guan)(guan)道(dao)頂(ding)(ding)進(jin)(jin)的方(fang)(fang)(fang)(fang)向和設計軸線方(fang)(fang)(fang)(fang)向不對應，應該(gai)用(yong)工(gong)作管(guan)(guan)內的調節(jie)千斤頂(ding)(ding)進(jin)(jin)行(xing)校正。管(guan)(guan)道(dao)的水(shui)(shui)平方(fang)(fang)(fang)(fang)向用(yong)水(shui)(shui)準儀(yi)進(jin)(jin)行(xing)測(ce)量(liang)糾偏，同樣(yang)是管(guan)(guan)子(zi)(zi)每頂(ding)(ding)進(jin)(jin)30cm，電力頂(ding)(ding)管(guan)(guan)施工(gong)，用(yong)水(shui)(shui)準儀(yi)測(ce)量(liang)管(guan)(guan)子(zi)(zi)兩端的高程，若有偏差需(xu)進(jin)(jin)行(xing)糾偏直到達(da)到施工(gong)要求(qiu)。

頂管施(shi)工和拉管施(shi)工直接的區別(bie)：

兩者(zhe)的(de)區別是，對于管(guan)(guan)道(dao)來說，拔管(guan)(guan)是通(tong)過鉆(zhan)機(ji)鉆(zhan)孔(kong)、擴孔(kong)等一系列程(cheng)序，使管(guan)(guan)道(dao)通(tong)道(dao)完成后，可以從(cong)這個通(tong)道(dao)中拔出管(guan)(guan)道(dao)；頂(ding)管(guan)(guan)方面(mian)，在管(guan)(guan)道(dao)前端設置頂(ding)管(guan)(guan)機(ji)頭，通(tong)過頂(ding)管(guan)(guan)機(ji)頭將前面(mian)的(de)土(tu)破碎成流變土(tu)或泥漿，通(tong)過管(guan)(guan)道(dao)后面(mian)的(de)千斤(jin)頂(ding)將管(guan)(guan)道(dao)向前推進。(有時(shi)頂(ding)管(guan)(guan)施工(gong)沒有機(ji)頭，采用(yong)人工(gong)挖土(tu)。)

頂(ding)管施(shi)工(gong)是一種(zhong)非開挖(wa)施(shi)工(gong)方法，是一種(zhong)不開挖(wa)或少(shao)開挖(wa)的管道(dao)埋設(she)施(shi)工(gong)技(ji)術(shu)。頂(ding)管施(shi)工(gong)是利用工(gong)作坑內頂(ding)進設(she)備產(chan)生的頂(ding)進力，克服管道(dao)與周圍土體的摩擦(ca)，按照(zhao)設(she)計要求將(jiang)管道(dao)推入(ru)土體，將(jiang)土方運出。一段(duan)管道(dao)頂(ding)入(ru)地面后(hou)，第二段(duan)管道(dao)將(jiang)繼(ji)續(xu)頂(ding)起。
