学习贯彻党的十九大精神】

这是管道三公司铁军微宣4158文章

3月13日,伴随着漫天白(bai)雪,在CPP311机(ji)组技术员的(de)指挥下,直径为2米的(de)水泥套管从明水县202国道一侧破土而出,标志着管道三公司中俄东(dong)线整(zheng)个(ge)标段的(de)顶管任务已(yi)经全部完成(cheng)。

此次顶(ding)管(guan)地(di)点位于(yu)明水(shui)县AL047号桩,穿越长(zhang)度84米,穿越用水(shui)泥套(tao)管(guan)42根。由(you)于(yu)202国(guo)道是黑龙江省的一条(tiao)交通要道,车流量(liang)极大(da)。整个(ge)施(shi)工过(guo)程中(zhong),三公司(si)项目部工程技术和安(an)全(quan)部门派专人进(jin)行(xing)全(quan)过(guo)程技术支持和安(an)全(quan)监控,同时(shi)加大(da)机具检查频次,严格(ge)按照施(shi)工规范,有效地(di)消除各类安(an)全(quan)隐(yin)患,确保了(le)施(shi)工质量(liang)。

整个顶(ding)(ding)(ding)(ding)管(guan)作业需要在施工(gong)前先确定(ding)两(liang)侧顶(ding)(ding)(ding)(ding)管(guan)准(zhun)确位(wei)(wei)置及标(biao)高和两(liang)侧埋地(di)(di)(di)光缆(lan)、管(guan)道等(deng)(deng)地(di)(di)(di)下障碍物,然后开挖工(gong)作坑(keng),将(jiang)千(qian)斤(jin)顶(ding)(ding)(ding)(ding)、顶(ding)(ding)(ding)(ding)管(guan)机(ji)(液压站)、扒渣机(ji)、顶(ding)(ding)(ding)(ding)铁(tie)等(deng)(deng)设备安装就位(wei)(wei),吊装套(tao)管(guan)、安装顶(ding)(ding)(ding)(ding)环(huan)(huan),利用(yong)液压千(qian)斤(jin)顶(ding)(ding)(ding)(ding)顶(ding)(ding)(ding)(ding)推套(tao)管(guan)。每(mei)顶(ding)(ding)(ding)(ding)进一定(ding)行程(cheng),退回顶(ding)(ding)(ding)(ding)缸,使(shi)用(yong)扒渣机(ji)挖土(tu),人工(gong)配(pei)合外运,然后加入顶(ding)(ding)(ding)(ding)铁(tie)或套(tao)管(guan)继(ji)续顶(ding)(ding)(ding)(ding)进,循环(huan)(huan)作业,直(zhi)至套(tao)管(guan)顶(ding)(ding)(ding)(ding)至对面接收坑(keng)。项目安全总监陶志介绍说(shuo):“现场虽小,却是处处有(you)用(yong)。每(mei)一寸(cun)土(tu)地(di)(di)(di)都(dou)有(you)自己的(de)功能,分区明(ming)确,谁都(dou)不越‘雷池’半步。”

据了解(jie),管(guan)道(dao)三公司承担的中(zhong)俄东线工程第五标段68.62公里内(nei),顶管(guan)任务共有7处(chu),大开(kai)挖施工多达40多处(chu)。为了不(bu)影响施工进(jin)(jin)度,  三公司项目部以(yi)“三个提前(qian)(qian)”全(quan)力保障焊接(jie)顺序进(jin)(jin)行(xing)(xing)。即:提前(qian)(qian)对所(suo)(suo)需开(kai)挖、顶管(guan)道(dao)路办理通(tong)过手(shou)续;提前(qian)(qian)多次(ci)进(jin)(jin)行(xing)(xing)实地勘测,确(que)认光缆位置(zhi)和所(suo)(suo)属管(guan)理单位;对需要(yao)顶管(guan)的道(dao)路提前(qian)(qian)开(kai)挖基坑,进(jin)(jin)行(xing)(xing)顶管(guan)作业。
