Under conditions such as load Xiong pvc corrugated pipe, HDPE double wall corrugated pipe requires only a thin wall to meet the requirements. Therefore, with the same double-wall corrugated pipe material specifications with solid wall pipe than can save about half of the raw material, so HDPE double wall corrugated pipe cost is lower. This is also a very prominent feature of the pipe. Xiong Wang Thai plastic construction process measurement is mainly determined bottom elevation after mechanical excavation pvc bellows standards, using measuring pvc bellows with machine manufacturers, with the digging measure to eliminate the phenomenon of over-excavation to ensure the bottom Elevation meet the design requirements, the pipeline installation pvc bellows, retest, identify problems in time, so that the tube bottom elevation is controlled within the range of tolerance. Measured daily before work begins, the standard of review should be carried out adjacent to the measurement. Pipeline control center by the middle pile to determine, by controlling stake in the pipeline based on the sideline play to determine the location of the pipeline laying. Well elevation control room design requirements, after the pipeline is completed, the need for the completion of the review of the measuring tube top and structures.
