    气囊堵水的轻松清理介绍
    2016-11-29 17:17:07 http://www.sggdst.com
    了解工作管段的水流状况,上游水流来源及管网分布情况,各支线管道来源及水流量情况、作业口尺寸,与管道调度部门协调、商议、预定停水、堵水、调水的方案。包括水分流方案,相关泵站水压控制,支管封堵方法。使用器具清单,制订安全防护措施,根据施工管段的管道口径,制作相应的钢制法兰三通(该三通的用途是施工结束后封堵气囊的出口),准备相应口径的法兰闷板,
    To understand the working pipe flow, upstream flow sources and distribution network, each branch pipeline source and water flow, operation port size, and pipeline scheduling coordination, consultation, scheduled suspension of water supply, water plugging, water diversion project. Including water diversion scheme, related pump pressure control, pipe plugging method. The use of apparatus list, making security protection measures, according to construction of pipe diameter, make the steel flange three (use of the three way is to export plugging airbag after construction), the corresponding diameter of the flange for boring plate,
    由于我们采购了一个有导流孔和一个无导流孔的管道封堵气囊,采用无导流孔管道封堵气囊。第二次试验在DN200mm口径的管段内实行,采用有导流孔管道封堵气囊。工作人员佩戴防护面具和安全保护用具,由专人在地面监护,测量封堵气囊进入的管道直径,确保尺寸在封堵气囊的使用范围内;在插入管道封堵气囊之前,清洁封堵气囊其外部以及封堵气囊即将进入的管道内部,将封堵气囊的一端(带有气嘴的一端)用牵引绳拉住,慢慢将封堵气囊放入管道,放入过程注意管口,避免损坏堵水气囊。
    As a result of our procurement of a diversion hole and a no flow diversion of the pipe blocking the air bag, the use of no diversion pipe plugging the air bag. The second test was carried out in the pipe section of the DN200mm caliber, and the air bag was sealed by the diversion hole pipe. Staff wearing protective masks and safety protection equipment, by the person on the ground monitoring, measuring the diameter of pipeline plugging into the air, to ensure that the size in the range of use plugging airbag; before insertion of pipeline plugging airbags, airbag and its external cleaning plugging plugging air bag inside pipeline will enter the end (end with the airbag will be closed the gas nozzle) with a traction rope pulled slowly into the pipeline plugging airbags, in the process of attention to avoid damage to pipe water bag.
    在给堵水气囊充气之前,应将其完全插入管中,插入气管,连接好气压表和气泵,启动气泵,开始充气,缓慢打开压力控制表的气阀,充气压力控制在压力标的红色区外的安全区域内。观察堵水气囊的充气状况,确认充气状态开始后,工作人员撤离。确保在充气期间无人在管道附近, 拉紧牵引绳,将绳在枕木上绑扎牢固,通过压力控制表,观察堵水气囊气压数据,当堵水气囊气压达到技术规定数时,关闭气压控制阀门,充气结束。
    Before the water blocking the air, it should be completely inserted into the tube, inserted into the trachea, connect the pressure gauge and pump, start the pump, start slowly inflated, open the valve pressure control meter, pneumatic pressure control pressure in the safe area outside the region in red mark. To observe the air condition of the air bag of the air bag, and confirm that the staff member is evacuated after the beginning of the inflation condition. To ensure that in the aeration period unmanned near the pipeline, the traction rope, the rope on the sleepers secured by the pressure control table, observation of water plugging air pressure data, when the air pressure of water plugging technology to achieve a predetermined value, the pressure control valve is closed, the inflation is over.
    充气结束后,20分钟内压力控制表保持与气管连接,观察封堵气囊压力的数据变化情况,一切正常,即可开始管道施工作业。管道封堵以及其他作业中,派专人监视检查封堵气囊的气压,与作业现场人员保持良好稳定的通讯,遇有异情及时报告,确保作业人员的安全。
    After the end of the inflation, 20 minutes to maintain the pressure control table and air pipe connection, observation of the data changes in the pressure of the air bag sealing, all normal, you can start the pipeline construction work. Pipeline plugging and other operations, send someone to monitor the air pressure of the sealing bag, and job site personnel to maintain good and stable communication, in case there are different feelings timely reporting, to ensure the safety of the operator.
