PVC pipe laying grid PVC pipe laying grid when laying pipe in the trench to prevent the arch .. before laying pipe, the ends should be first nozzle tight sealing to prevent water, soil and other debris into the tube. Pipeline in the ditch should be straight. After laying the pipeline should be sealed as soon as the connection for the introduction of manhole pipe port should be blocked. According to design requirements tied with wire every certain distance. When the pipe trench of water, the water should be drained prior to wrap pipes. When laying the pipe grid tube should be immediately picked up from the bottom through the obstacles, avoid skin mopping pipe after pipe laying should be back to earth buried 300mm, straight-walled pipe exposed to minimize time to prevent pipes being human and other kinds of damage. Application grid tube introduced through plastic Products Co., Xiong gold on porous pipe perforated grill grid tube is called porous, because it has a plurality of holes, including hole perforated grid tube tube grille, four aperture grille tube, five-hole grid tubes, tin tube grille, grille tube abalone, performance advantages: 1. PVC pipe grid tubes offer communication, PVC pipe grid square shape structure for arc angle grid tubes, arranged in neat and convenient. Small footprint, only 10% of the cement tube position, the small amount of excavation, the effect of urban underground space saving tin grid tube, little impact on road traffic and municipal. 2. Communications PVC pipe, PVC pipe tube grille light weight, handling than metal pipes and cement pipes easy and convenient. Simple construction and installation, small construction strength, low construction cost. 3. Communications PVC pipe, PVC grid tube good toughness, good bending performance, some six meters long pipe, bending strings high up above 1.2 4-hole grid tube, can be connected with a special variant dedicated to the elbow. Encountered during the construction of the curve or crossing other pipelines can be easily avoided. 4. Communications PVC pipe, PVC pipe bending modulus grill is good, completely solve the metal pipe perishable disadvantage without distortion resilient. 5. Corrosion resistance, good insulation and flame retardant, anti-static. 6. Communications PVC pipe, PVC pipe interface has assembled grill marks, take orderly rows; for pressure, requires only 0.3-0.5 m depth, without foundation and cement encapsulation, the first fine sand backfill 20 cm return to fill that be open to traffic.
