Drainage security orifice located troughs and peaks due to the dual role of the filter fabric, orifice clogging, to ensure the smooth flow of permeable system. Corrosion resistance compared with the soft spring drains, plastic not rust. Strength and unique double corrugated flexible structure effectively raising the external pressure strength of the product, the drainage system is not affected by outside pressure deformation drainage effect. Cheap compared to other same caliber drains, lower its price. Construction buried drain requires editing a prior roadbed subbase construction unit to carve with horizontal drains buried two slotted: In accordance with the design drawings and design station location surveyors Laying of artificial slotted .PE pipe width is slightly wider than the diameter of 1 to 2 cm φ100pvc drains, groove depth of 23 cm under the road bed surface. slot length of 10 cm from the midline requirements medial, lateral out into the slope, by digging ditches out into interior . slope to drop lateral groove drainage slope may not be anti-slope, to ensure that the water discharged embankment road outside the front slot to pull the drain pvc specifications to ensure straight Junzo take over: two interfaces each PVC pipe After the matter must cover pvc drainage pipe wall thickness apron, to avoid leakage [1] Fourth, the down tube: cleaned up the bottom, connected by a long groove tube, put the tube into the tank, at the side of the median strip the first use of the port truss sack cloth to prevent debris into the tube pvc u clogged drains |. drainage | plastic two-out double by Xiong Zan Kong Ming plastic products factory.
