Zhongshan drainage boardZhongshan plastic drainage boardConstruction Method:
1. Finished tools used in Zhongshan plastic drainage board: hair dryer, cutting, brush, broom, etc.
2.Cracks within 20 cm on both sides of the road are cleaned with blowers. If there are growers in the Zhongshan drainage board, rinse with water to keep the base clean and dry.
3.Remove the surface seam and trim the surface seam that is slightly longer than the crack length.
4. Zhongshan plastic drainage board dismantling isolation paper (in the case of low surface temperature, evenly coated with glue on the side of the insulating paper disassembled, or repair the emulsified asphalt on both sides of the crack to ensure the mortar effect).
Zhongshan drainage boardZhongshan plastic drainage boardMerit.
1. No clogging: direct use of natural gravity phenomenon to produce the effect of water separation, 2. Permeability properties: the opening rate is up to 20%, and the effective water absorption area is large.
3. High drainage efficiency: the use of capillary force, siphon force, and high drainage efficiency
4. Zhongshan drainage plate has strong earth pressure resistance: arch bridge structure design, effective dispersion of stress distribution;
5. Need-free grading: with self-cleaning function, no need to grade filter layer, can be directly covered with soil and backfilled.
6. The construction of Zhongshan plastic drainage board is simple: the roll type packaging does not occupy the volume, reduces the cost of transportation, storage, management and work, and does not need to increase the rate of joints;
6. Flexure and flexibility: it can be closely attached to the terrain to form an infinitely long and non-flattened water flow highway
8. Good durability: PVC high-density polymer material is used, which is ultraviolet-resistant and durable.
Zhongshan drainage boardZhongshan plastic drainage boardPerformance:
Because the water (water molecule) geotextile has a certain permeability to the polymer material, especially under the action of heat, this permeability will be enhanced, so that it can penetrate into the material system and accumulate. At the same time, the infiltration of water into Zhongshan plastic drainage board leads to the dissolution, extraction or migration of additives and other soluble substances in the polymer material system, which changes the physical and mechanical properties of the material. Due to the infiltration of water molecules, the interaction force between some material molecules decreases, resulting in a decrease in the mechanical properties of the material.
