Cable duct waterproof plugging tendency

2013-12-05

Along with the city construction and development and the requirements of modern construction technology and quality requirements continue to increase, the pneumatic pipe plug to replace cement plugging cement material for sealing of cable pipe, has become a trend.配電房電纜套管密封
First of all, the traditional cement plugging higher demands on the construction conditions, labor intensity is relatively large. In addition to the transport of cement, river sand, also need to connect the water, when construction also need shovels, ash bucket, the pole of various construction tools. And the use of pneumatic pipe plug to plug, is relatively fast and convenient, greatly reduce the labor intensity. In addition, the cement plugging needs good weather, need to dry environment, if it rains, you cannot construction. The pipeline and pneumatic pipe plug can be applied to soaking, is not affected by the weather and water pipes, whenever and wherever possible to install.開關站電纜孔洞
Secondly, cement plugging removal difficult. When the pipeline expansion or repair, in the face of pipeline sealed cement mouth, need to use the tool easily beat, cut down, but also to avoid damage of pipeline or cable, operation control efforts to the construction personnel requirements are relatively high. While the use of inflatable tube plugging pipe mouth, only needs to be inflated tube ceza holes, the internal air discharging, the construction personnel easily can be removed, so that not only will not damage the pipeline and cable, but also greatly save construction time.封堵施工現場
Finally, on the plugging effect, the inflation tube plugging is much better than using cement plugging. First, the inflation tube plugging weather resistance and thermal expansion and contraction effect is better, the effective seal time longer; two, the cable cement plugging fixed dead, do not move at all, if the initiative on behalf of the gap, the waterproof effect is lost. The cable pipe plugging can bear small distance to drive, can also make a 45 degree bend, waterproof sealing effect is not affected, provided certain operating space and room for repair work.
