We all know that the laying of pipes used in communications, telecommunications, cable tube it? Pvc grid tubes, this pvc grid tube to protect our normal communication, has made tremendous contributions to our communication system, today we have to talk about pvc grid tube! Raster PVC pipe cross-section into a number of square structure composed of porous rectangular (corner portion has a certain curvature) plastic pipe. The product has a number of holes, can wear the cable, at the same time can be set aside pores to improve the utilization of communication holes. Let's say PVC the grid tube the how laying!

As we all know?
Grid pvc pipe fittings trenching buried in the ground, we said trench excavation to prepare before speaking: before excavation, the excavation plan should be prepared to check with excavation conditions, reported Supervision approval before implementation. Trench excavation should be construction specification requirements. After when the trench is dug, it is necessary to raster pvc pipe fittings laid! Laying the pipe in the trench to prevent the hump. Before being laid, the pipe should first both ends of the tube mouth tight closure to prevent water, soil, and other debris from entering the tube. pvc grid pipes in the ditch should be straight. Pipeline laying seal should connect the pipes to the introduction of the manhole should promptly port blocking. According to the design requirements of every certain distance, tied up with wire. Pipe trenches, water and wrap the pipe before the water should be drained. Should immediately laying pipe from obstructions below through the grid tube picked up to avoid tube skin mopping. Pipe laying should be back to the soil buried 300mm, to minimize the straight wall tube bare time to prevent the pipe by the man-made and a variety of other injuries. These work done to trench backfill! To go through the supervising engineer Verify that meet quality standards before backfilling before backfilling required thickness fine soil or Suitu of required height of backfill.
