分析螺旋输送机注浆管堵塞问题

文章来源:郑州赛德斯机械 发布时间:2017-01-23 浏览次数:
螺旋输送机在注浆过程中经常会出现注浆管堵塞问题,这是经常困扰技术人员的一个问题,由于螺旋输送机在注浆过程中很容易出现着这种问题,这就造成螺旋输送机注浆的问题,使得螺旋输送机的注浆不能正常完成,给螺旋输送机的使用造成一定的危害。为什么会出现螺旋管注浆管堵塞问题以及该怎样避免出现这种问题呢?
The screw conveyor during Grouting grouting pipe blocking problem often occurs, this is a problem often plagued by technical personnel, the screw conveyor in the grouting process is prone to this problem, which will cause the screw conveyor grouting, the grouting screw conveyor can not be completed properly, causing some harm to use screw conveyor. Why is there a spiral pipe grouting pipe blockage and how to avoid this problem?
注浆管堵塞其主要原因是水泥浆液从拌合站拌料到注浆过程的时间太长、盾构停机时间太长未对注浆管路进行清洗,以致浆液达凝固时间而易沉淀附着在注浆管内壁,最终造成管路堵塞。解决注浆管堵塞问题的关键就是要缩短从拌合站拌料到注浆的时间、合理调整浆液配合比、长时间停机对盾构注浆管路的清洗。
The main reason is the jam of grouting pipe grouting cement slurry mixing process expected time from the mixing station is too long, too long not to stop the shield grouting pipe cleaning, so as to precipitate the solidification time of slurry on the inner wall of the grouting pipe attachment, resulting in blockage of pipeline. To solve the key problems of grouting pipe blockage is shortened from mixing station mixing expected time, reasonable adjustment of grouting slurry mixture ratio, long time cleaning of shield grouting pipe.
具体采取的措施为:地面拌合站拌浆至井下砂浆车中途下料要采用大口径输送管放浆,缩短放浆时间,同时将浆管口尽可能靠近浆液车底部,打开闸门即可依靠浆液自重放浆;紧凑安排工序,缩短浆液在隧道内的运输时间;在洞口位置设置电源插座,专供砂浆车搅拌电机用,保证砂浆车搅拌器正常连续工作,避免因施工停顿时间过长而引起浆液离析沉降堵塞注浆泵;砂浆车向盾构机储浆罐泵浆时,降低出浆管高度,同时开启搅拌机搅拌浆液;在不影响其他管路及运作空间的前提下,适当改善同步注浆管路,减少弯头、增大管径,避免浆液在管路中沉积、堵塞;盾构机长时间停机无法掘进停机时,及时对盾构机注浆管路、砂浆车罐及注浆泵进行清洗,防止浆液在注浆管路、盾尾中凝固堵塞。
Specific measures: ground mixing station mixing mortar to the underground car halfway down the material to use large diameter pipe on the slurry, shorten the time at the same time will put slurry, slurry nozzle as far as possible near the bottom slurry car, open the gate to rely on the weight placed grout slurry; compact arrangement process, shorten the slurry in the tunnel transport time; set power socket in the hole position for mortar vehicle with a stirring motor, to ensure the normal work of continuous mixer mortar vehicle, avoid the construction pause time is too long and cause segregation of slurry sedimentation blockage grouting pump; mortar vehicle to shield slurry storage tank for slurry pump, reduce slurry pipe height, while opening the mixer in the slurry; without affecting other pipelines and operation space, improve the synchronous grouting pipe, reducing elbow, increase the diameter, slurry deposition in the pipeline, to avoid clogging; When the captain of the shield machine is unable to stop the machine when the machine is stopped, the grouting pipe, the mortar tank and the grouting pump can be cleaned in time.
