小(xiao)編為(wei)您分享非(fei)開挖相(xiang)關知識：

在非開挖(wa)工程(cheng)公司泥水頂管的施工過程(cheng)中(zhong)，還必須注意以(yi)下(xia)幾(ji)個(ge)問(wen)題

1.當掘進(jin)機停止(zhi)工作(zuo)時，一(yi)定要防止(zhi)泥水(shui)(shui)從土層中或洞口及其他(ta)地方流失。不然，挖掘面就會失穩(wen)，尤其是在出洞這一(yi)段時間(jian)內(nei)更應防止(zhi)洞口止(zhi)水(shui)(shui)圈漏水(shui)(shui)。

2.在掘(jue)進過程中，應注(zhu)意(yi)觀(guan)察(cha)地下水壓力(li)的變(bian)化，并及時采取相應的措施和對策(ce)，只(zhi)有這樣(yang)，才(cai)能保持挖(wa)掘(jue)面的穩定。

3.在(zai)頂(ding)進(jin)過(guo)程中(zhong)，隨時要注意(yi)挖掘(jue)面是(shi)否(fou)穩定，要不時檢査泥水(shui)的濃度(du)和相對(dui)密度(du)是(shi)否(fou)正常，還要注意(yi)進(jin)排(pai)泥泵的流量及(ji)壓力是(shi)否(fou)正常。應防止排(pai)泥泵的排(pai)量過(guo)小而(er)造(zao)成排(pai)泥管的淤積和堵塞現象。

小編為您分(fen)享非開(kai)挖相關知(zhi)識：頂管施工的施工工藝(yi)

頂管施(shi)工比開槽施(shi)工復雜(za)，容易產(chan)生偏差，因此(ci)對管道(dao)(dao)中心線和頂管的(de)起點、終(zhong)點標高(gao)等都應地確定，做好(hao)頂進過程中的(de)偏差校(xiao)(xiao)正(zheng)。 當測量(liang)發現偏差在10mm左右，即(ji)應進行(xing)校(xiao)(xiao)正(zheng)。校(xiao)(xiao)正(zheng)是逐(zhu)步進行(xing)的(de)，偏差形成后，應緩慢進行(xing)校(xiao)(xiao)正(zheng)，使管道(dao)(dao)逐(zhu)漸復位(wei)，禁止猛(meng)糾硬調。

可采用(yong)超(chao)(chao)挖(wa)糾(jiu)偏(pian)(pian)法，即(ji)在偏(pian)(pian)向(xiang)的反側適當超(chao)(chao)挖(wa)，在偏(pian)(pian)向(xiang)側不超(chao)(chao)挖(wa)，甚(shen)至留坎，形成阻力，施(shi)加頂(ding)(ding)力后(hou)，非開挖(wa)管(guan)(guan)道(dao)施(shi)工項目承包(bao)，使偏(pian)(pian)差回歸。當偏(pian)(pian)差大于20mm時(shi)，采用(yong)千斤頂(ding)(ding)糾(jiu)偏(pian)(pian)法，非開挖(wa)污(wu)水管(guan)(guan)道(dao)工程，當超(chao)(chao)挖(wa)糾(jiu)偏(pian)(pian)不起作用(yong)時(shi)，用(yong)小型千斤頂(ding)(ding)頂(ding)(ding)在管(guan)(guan)端偏(pian)(pian)向(xiang)的反側內管(guan)(guan)壁上，另一端斜撐在有墊(dian)板的管(guan)(guan)前土壁上，晉(jin)中非開挖(wa)，支頂(ding)(ding)牢(lao)固后(hou)，即(ji)可施(shi)加頂(ding)(ding)力。同時(shi)配(pei)合超(chao)(chao)挖(wa)糾(jiu)偏(pian)(pian)法，邊頂(ding)(ding)邊支，直至使偏(pian)(pian)差回歸。

頂管施工中施工井如何布置？

井(jing)內布置內容主要(yao)(yao)包(bao)括(kuo)前止水(shui)墻、后座墻基礎底板及排水(shui)井(jing)等。后座要(yao)(yao)有(you)足夠(gou)的抗壓(ya)強(qiang)度，能承受得了主頂千斤頂的大頂力前止水(shui)墻上安裝(zhuang)有(you)洞(dong)口止水(shui)圈，以防(fang)止地(di)下水(shui)土(tu)及頂管用(yong)潤滑泥(ni)漿的流(liu)失。

在頂管工作(zuo)井內，還(huan)布置有工具管、環形頂鐵(tie)、弧形頂鐵(tie)、基坑導軌(gui)、主頂千斤頂及千斤頂架、后靠背。

其中(zhong)主頂(ding)千斤頂(ding)及千斤頂(ding)架的布置尤為重(zhong)要(yao)，主頂(ding)千斤頂(ding)的合力(li)的作用(yong)點(dian)對于(yu)初始頂(ding)進的影(ying)響比較大(da)。
