定向(xiang)鉆頂(ding)管(guan)施工頂(ding)進(jin)前，人工向(xiang)前挖土(tu)與機(ji)(ji)頭刀(dao)盤(pan)相(xiang)同的距(ju)離(li)；向(xiang)前推(tui)入機(ji)(ji)頭，至刀(dao)盤(pan)完全進(jin)入洞壁；開動機(ji)(ji)頭刀(dao)盤(pan)；機(ji)(ji)頭刀(dao)盤(pan)開動后(hou)，開動糾偏(pian)千斤(jin)頂(ding)，對機(ji)(ji)頭頂(ding)進(jin)方位進(jin)行校(xiao)準(zhun)調偏(pian)；先(xian)將刀(dao)盤(pan)推(tui)入后(hou)，可以預先(xian)通過調偏(pian)和校(xiao)準(zhun)，減少后(hou)續頂(ding)進(jin)的偏(pian)移；

下沉管道和頂(ding)鐵后(hou)，先用頂(ding)鐵向(xiang)(xiang)(xiang)前(qian)頂(ding)進(jin)(jin)管道，山西定(ding)(ding)向(xiang)(xiang)(xiang)鉆頂(ding)管施工，至(zhi)管道間的(de)密(mi)(mi)封圈緊密(mi)(mi)貼合(he)；頂(ding)進(jin)(jin)至(zhi)少兩節(jie)管道后(hou)，吊出頂(ding)鐵；在后(hou)一節(jie)管道后(hou)端(duan)安裝剛套環(huan)；鋼套環(huan)與(yu)管道后(hou)端(duan)通(tong)過(guo)法蘭連接(jie)；鋼套環(huan)和其(qi)前(qian)面的(de)管道，水平定(ding)(ding)向(xiang)(xiang)(xiang)鉆頂(ding)管施工工藝，在達到接(jie)收井后(hou)，通(tong)過(guo)法蘭相互拆除，并吊出接(jie)收井；

泥漿輸送管和電路(lu)線路(lu)鋪(pu)設在頂進(jin)機頭(tou)和剛套環之間的(de)(de)管道(dao)內；泥漿輸送管和電路(lu)線路(lu)均通(tong)過(guo)鋼(gang)套環底(di)部預留的(de)(de)通(tong)道(dao)穿出；泥漿輸送管和電路(lu)線路(lu)位于(yu)管道(dao)內且跟隨(sui)機頭(tou)向前移動；減少因管路(lu)向前頂進(jin)導致對線路(lu)的(de)(de)損(sun)害(hai)。

正常頂進(jin)結束后(hou)，排干(gan)降(jiang)水井(jing)(jing)內(nei)的水，并用碎石對降(jiang)水井(jing)(jing)進(jin)行回(hui)(hui)填(tian)；吊(diao)出機頭；注入觸(chu)變泥(ni)漿；回(hui)(hui)填(tian)降(jiang)水井(jing)(jing)防止施工(gong)結束后(hou)出現塌陷。

小編為(wei)您分(fen)享定向(xiang)鉆頂管(guan)施工相關知識：頂管(guan)施工引起的地面(mian)變(bian)形分(fen)析

1)掘(jue)進機到達前的(de)地面(mian)變形

當掘進機(ji)離測點較遠時，由于刀盤的(de)切削攪拌(ban)、振動，會(hui)(hui)對(dui)土體(ti)(ti)(ti)產生擾動。土體(ti)(ti)(ti)顆粒之間存在(zai)孔(kong)隙(孔(kong)隙中含有水(shui)和(he)空(kong)氣(qi))，在(zai)擾動作用下，孔(kong)隙中的(de)水(shui)和(he)氣(qi)體(ti)(ti)(ti)被排出，土體(ti)(ti)(ti)顆粒相對(dui)移動，土體(ti)(ti)(ti)產生了壓縮，地面會(hui)(hui)出現微小的(de)沉(chen)降。

(2)掘進機(ji)到達時的地面變形

當掘進(jin)機距離很(hen)近時，位于(yu)掘進(jin)機正前方的土體，受(shou)到(dao)千斤頂(ding)推力(li)的擠(ji)壓、刀盤的切削剪切力(li)以及振動荷(he)載的作用，應力(li)狀(zhuang)態(tai)十分復(fu)雜。

(3)掘(jue)進機通過時(shi)的地面變形(xing)

當掘進(jin)機通(tong)過時，掘進(jin)機外殼與(yu)土(tu)層(ceng)(ceng)間會形成(cheng)剪切(qie)滑動(dong)面，剪切(qie)滑動(dong)面附(fu)近(jin)的土(tu)層(ceng)(ceng)內產生剪切(qie)應(ying)力(li)，剪切(qie)應(ying)力(li)引(yin)起地面變形。推進(jin)速度越快，剪切(qie)應(ying)力(li)越大(da)，周圍土(tu)體位移也越大(da)。
