小編為您分(fen)享(xiang)管道工(gong)(gong)程相關知識：PE頂管施工(gong)(gong)方案(an)

1.施工準備階段

施工準備階段主要包括管(guan)材(cai)的選(xuan)用(yong)，此時選(xuan)擇防腐(fu)性能好(hao)，相對(dui)流體阻力(li)小的聚乙烯材(cai)料管(guan)道。

2.制孔

此階段(duan)主要(yao)包括制導向(xiang)孔(kong)和擴孔(kong)。制導向(xiang)孔(kong)時，行(xing)(xing)導向(xiang)孔(kong)軌跡設計(ji)，雨水(shui)管道工程多少錢，接下來進(jin)(jin)(jin)行(xing)(xing)導向(xiang)鉆(zhan)進(jin)(jin)(jin)，鉆(zhan)進(jin)(jin)(jin)時要(yao)注意避(bi)免使用彎曲和有傷的鉆(zhan)桿;鉆(zhan)孔(kong)時，進(jin)(jin)(jin)給速(su)度不能過(guo)大(da)，制定合理的進(jin)(jin)(jin)給速(su)度;另外要(yao)行(xing)(xing)試運(yun)(yun)轉(zhuan)，在確(que)定運(yun)(yun)轉(zhuan)正常之后方可開始鉆(zhan)進(jin)(jin)(jin)。在制孔(kong)完成后，進(jin)(jin)(jin)行(xing)(xing)回位(wei)擴孔(kong)工作。

3.鋪設管道

接著利用(yong)(yong)(yong)進(jin)行焊接和(he)加(jia)(jia)固工作。保(bao)證兩根管(guan)(guan)子同軸后，使用(yong)(yong)(yong)熱熔機完成兩根聚乙烯頂管(guan)(guan)的焊接。在(zai)加(jia)(jia)固時，在(zai)PE管(guan)(guan)外(wai)部用(yong)(yong)(yong)鋼管(guan)(guan)進(jin)行護管(guan)(guan)，雨(yu)水管(guan)(guan)道工程廠家，并在(zai)鋼套(tao)管(guan)(guan)外(wai)部綁(bang)上鋼筋(jin)以用(yong)(yong)(yong)于加(jia)(jia)固工作。如果是替換舊管(guan)(guan)，則(ze)利用(yong)(yong)(yong)液(ye)壓膨脹器(qi)(qi)和(he)氣動錘(chui)利用(yong)(yong)(yong)擴張器(qi)(qi)進(jin)入土層，然后將新(xin)管(guan)(guan)拉入。

本公司主營：山西頂管(guan)(guan)(guan)施(shi)(shi)(shi)工(gong)(gong)、太(tai)原頂管(guan)(guan)(guan)施(shi)(shi)(shi)工(gong)(gong)、山西非(fei)(fei)開挖施(shi)(shi)(shi)工(gong)(gong)、太(tai)原非(fei)(fei)開挖管(guan)(guan)(guan)道施(shi)(shi)(shi)工(gong)(gong)、山西人工(gong)(gong)頂管(guan)(guan)(guan)施(shi)(shi)(shi)工(gong)(gong)、太(tai)原過路(lu)頂管(guan)(guan)(guan)施(shi)(shi)(shi)工(gong)(gong)、山西巖石頂管(guan)(guan)(guan)工(gong)(gong)程、太(tai)原定向鉆頂管(guan)(guan)(guan)施(shi)(shi)(shi)工(gong)(gong)、山西非(fei)(fei)開挖頂管(guan)(guan)(guan)施(shi)(shi)(shi)工(gong)(gong)、太(tai)原泥水平衡頂管(guan)(guan)(guan)施(shi)(shi)(shi)工(gong)(gong)、管(guan)(guan)(guan)道工(gong)(gong)程

小編為(wei)您分(fen)享管道(dao)工程相關知識：mpp頂管施工

mpp頂(ding)管(guan)施(shi)工(gong)的質(zhi)量(liang)和品質(zhi)會影響到市政甚(shen)至(zhi)居民安全，因此必(bi)須(xu)嚴格(ge)保證施(shi)工(gong)質(zhi)量(liang)，而這種機型的缺點是頂(ding)速慢，難以(yi)控制出(chu)土量(liang)。所以(yi)頂(ding)管(guan)公司在開(kai)鉆時，都先開(kai)風(feng)后(hou)開(kai)水(shui)，停(ting)鉆則(ze)采(cai)用(yong)先關(guan)水(shui)后(hou)關(guan)風(feng)，給水(shui)管(guan)道工(gong)程廠家，這樣做(zuo)是為了預防空(kong)運轉(zhuan)，液壓頂(ding)管(guan)機殘留水(shui)滴，盡可能多方(fang)向，多排頂(ding)進，以(yi)提(ti)高工(gong)作坑(keng)的利用(yong)效(xiao)率。

分(fen)類上，mpp頂(ding)管(guan)實際上是(shi)mpp電力管(guan)的(de)分(fen)支。mpp電力管(guan)分(fen)為(wei)普(pu)通型(xing)和加(jia)強(qiang)(qiang)型(xing)兩(liang)種。主要區分(fen)于(yu)其(qi)工(gong)程的(de)開(kai)挖(wa)(wa)深度，以(yi)4米(mi)為(wei)分(fen)水嶺(ling)，普(pu)通型(xing)適(shi)用于(yu)非開(kai)挖(wa)(wa)施工(gong)埋(mai)深小于(yu)4米(mi)的(de)工(gong)程;加(jia)強(qiang)(qiang)型(xing)適(shi)用于(yu)非開(kai)挖(wa)(wa)工(gong)埋(mai)深大(da)于(yu)4米(mi)的(de)工(gong)程。而(er)mpp頂(ding)管(guan)則是(shi)屬于(yu)加(jia)強(qiang)(qiang)型(xing)中的(de)非開(kai)挖(wa)(wa)管(guan)，又被稱(cheng)為(wei)mpp托拉管(guan)和mpp牽引管(guan)。

從前景上看，mpp非(fei)開(kai)挖(wa)管適應環保要求，避免因素，又(you)能實(shi)現如高(gao)速公路、保護區(qu)等無法或不適合(he)實(shi)施開(kai)挖(wa)作業(ye)的地區(qu)鋪設(she)管線，所以其必將被更(geng)廣泛應用(yong)于(yu)市(shi)政等更(geng)多管線工程。

小編(bian)為您分享管道(dao)工程相關知識(shi)：

泥水平衡(heng)頂(ding)管機施工如何防止工具管旋(xuan)轉？

①頂管(guan)施工中，刀盤實現恒功率輸出，軟地(di)層(ceng)，扭(niu)矩(ju)(ju)小，轉(zhuan)速高(gao)，硬地(di)層(ceng)扭(niu)矩(ju)(ju)大，轉(zhuan)速低，對地(di)層(ceng)適應(ying)性(xing)更好。

②頂(ding)管施工(gong)中，頂(ding)進前應逐臺調試(shi)千(qian)(qian)斤頂(ding)，采用同種規(gui)格的(de)液(ye)壓(ya)千(qian)(qian)斤頂(ding)，使(shi)其頂(ding)力(li)、行程、速(su)度一致，保持頂(ding)力(li)合(he)力(li)線(xian)與(yu)管道中心(xin)線(xian)相重(zhong)合(he)。

③頂管(guan)施工中，要時(shi)刻留(liu)意偏差發展的趨勢，以勤(qin)測量(liang)、勤(qin)糾偏、小量(liang)糾為原則，離石管(guan)道(dao)工程，多進行(xing)小幅度(du)糾偏和預見(jian)性(xing)糾偏，使偏差只(zhi)在(zai)小幅度(du)范圍內(nei)波動、盡量(liang)避免大角(jiao)度(du)糾偏。

④頂管施工中，工具(ju)管設(she)置測力(li)裝(zhuang)置，以便測定平衡力(li)的(de)大小指(zhi)導(dao)糾偏。
