小編為您分享管道工程相關知識：頂管施工前挖土要(yao)求(qiu)

管(guan)(guan)(guan)(guan)前挖(wa)(wa)土(tu)是(shi)保證頂進質(zhi)量和地上構筑物安(an)全的關鍵(jian)，挖(wa)(wa)土(tu)的方向和開(kai)挖(wa)(wa)的形狀直接影響(xiang)到頂進管(guan)(guan)(guan)(guan)位(wei)的準確(que)性，輸氣管(guan)(guan)(guan)(guan)道工(gong)(gong)程(cheng)施工(gong)(gong)，因此應(ying)嚴(yan)格(ge)控制(zhi)(zhi)管(guan)(guan)(guan)(guan)前周圍(wei)的超(chao)挖(wa)(wa)現象(xiang)，在(zai)一般頂管(guan)(guan)(guan)(guan)地段，如土(tu)制(zhi)(zhi)質(zhi)較好，可超(chao)挖(wa)(wa)管(guan)(guan)(guan)(guan)端(duan)300～500mm；對于密實土(tu)質(zhi)，在(zai)管(guan)(guan)(guan)(guan)端(duan)上面允(yun)許(xu)超(chao)挖(wa)(wa)15mm以內，以減(jian)少(shao)頂進阻力，管(guan)(guan)(guan)(guan)端(duan)下部(bu)135度(du)范圍(wei)內不得超(chao)挖(wa)(wa)，給(gei)排水管(guan)(guan)(guan)(guan)道工(gong)(gong)程(cheng)施工(gong)(gong)，保持管(guan)(guan)(guan)(guan)壁與土(tu)基表面吻合。

管(guan)道(dao)工程接口(kou)的處理：由于頂管(guan)的管(guan)材為F型接口(kou)，頂管(guan)完(wan)畢(bi)后，對于管(guan)與管(guan)之間的縫隙(xi)，采用(yong)膨(peng)脹(zhang)水(shui)(shui)(shui)泥(ni)砂(sha)漿壓實填抹。選用(yong)硅酸鹽膨(peng)脹(zhang)水(shui)(shui)(shui)泥(ni)和潔凈的中砂(sha)，配合比(bi)（重(zhong)量比(bi)）為：膨(peng)脹(zhang)水(shui)(shui)(shui)泥(ni)：砂(sha)：水(shui)(shui)(shui)=1:1:0.3，隨拌隨用(yong)，一次拌和量應在半小(xiao)時內(nei)用(yong)完(wan)。填抹前，將接口(kou)濕潤，再(zai)分層填入，壓實抹平后，在潮濕狀態下(xia)養護。

小編為您分享管道工程相關知識(shi)：泥水平(ping)衡頂管施工的施工優勢

泥水平(ping)衡頂(ding)管(guan)施工的(de)建設成本比手(shou)動(dong)頂(ding)管(guan)高，但在當地(di)質量條(tiao)件(jian)較快的(de)情(qing)況下，晉(jin)中管(guan)道工程(cheng)，比手(shou)動(dong)頂(ding)管(guan)。讓我們簡要了解頂(ding)管(guan)法在泥水平(ping)衡施工中的(de)優勢(shi)。

泥水(shui)平衡(heng)頂(ding)(ding)(ding)管(guan)利用頂(ding)(ding)(ding)管(guan)機(ji)施(shi)加的(de)泥漿(jiang)壓力來平衡(heng)頂(ding)(ding)(ding)管(guan)表面(mian)外的(de)水(shui)壓和土壓力，廢土以泥漿(jiang)形式(shi)排入頂(ding)(ding)(ding)管(guan)。液壓千斤頂(ding)(ding)(ding)用于將管(guan)道從工作井推向接收(shou)井，而無需挖地面(mian)。

地下水位高，不(bu)可能建立起諸如普通頂管(guan)(guan)(guan)之類的(de)(de)廣(guang)泛應用，并且泥(ni)水平(ping)衡施(shi)工方法是合適(shi)(shi)的(de)(de)。在泥(ni)水平(ping)衡頂管(guan)(guan)(guan)施(shi)工中，由于對泥(ni)漿的(de)(de)潤滑，總推力小(xiao)，特別適(shi)(shi)合于長(chang)距離(li)頂管(guan)(guan)(guan)施(shi)工。普通開挖土壤中頂管(guan)(guan)(guan)的(de)(de)摩擦力比較大，不(bu)適(shi)(shi)合長(chang)距離(li)頂管(guan)(guan)(guan)施(shi)工。

為什么非開(kai)挖(wa)維(wei)修(xiu)更實惠(hui)？

相比(bi)之下，較新的(de)(de)(de)(de)修復技術(shu)需要(yao)(yao)(yao)的(de)(de)(de)(de)時(shi)間要(yao)(yao)(yao)少得(de)多，而(er)且不涉及挖(wa)掘。首先，工作人員確定離(li)水(shui)管斷裂近(jin)的(de)(de)(de)(de)接入點(dian)。使(shi)用靈活的(de)(de)(de)(de)攝像機(ji)系統(tong)(tong)，檢查(cha)管道(dao)(dao)以(yi)找到泄漏或的(de)(de)(de)(de)確切(qie)位置(zhi)。一旦發現，排污管道(dao)(dao)工程廠家，將涂有環氧樹脂(zhi)的(de)(de)(de)(de)襯套旋入主管道(dao)(dao)，直至到達損壞區域。然后將其充氣，使(shi)其壓在管道(dao)(dao)的(de)(de)(de)(de)內(nei)壁(bi)上(shang)。當環氧樹脂(zhi)固化時(shi)，襯里基本上(shang)會在現有管道(dao)(dao)的(de)(de)(de)(de)內(nei)部形(xing)成一層新的(de)(de)(de)(de)管道(dao)(dao)。這(zhe)可以(yi)密封(feng)主管道(dao)(dao)并對其進(jin)行維修，而(er)無需將其從地面上(shang)移除。因為這(zhe)個過程比(bi)傳(chuan)統(tong)(tong)方法少得(de)多，而(er)且只需要(yao)(yao)(yao)一小(xiao)部分時(shi)間、勞動力和設備(bei)，非開挖(wa)下水(shui)道(dao)(dao)的(de)(de)(de)(de)維修成本要(yao)(yao)(yao)低得(de)多。
