Plastic track is more common in our daily life, and it is more comfortable to do sports on this track. Generally this kind of runway will have corresponding drainage ditch, so do you know what construction precautions for this kind of drainage ditch?
1. The drainage ditch structure conforms to the relevant national "plastic runway construction design standards" (including the size of the ditch body, the size of the cover, the elevation of the ditch bottom, etc.).
2. Settling wells in the drainage ditch every 20-30m should meet the design requirements.
3. The drainage ditch cover is designed with single or double holes. The drainage ditch cover should be installed firmly without swinging. The gaps between each cover should be evenly distributed (about 10mm) and smoothed with cement mortar.
4. The inner wall of the drainage ditch shall be treated with waterproof mortar and dust in strict accordance with the waterproof requirements.
5. The movable manhole covers on the drainage ditch cover plate (including the sinking manhole cover, water section door manhole cover, etc.) should be installed firmly and easy to open.
6. The compactness of the foundation backfill of the outer wall of the drainage ditch should reach the standard of more than 95% to prevent the settlement and deformation of the ditch from causing plastic deformation or cracking between the ditch and the runway.
7. If the water supply system is installed in the drainage ditch of the plastic runway at the same time, the water supply pipeline should be installed firmly and reliably. In the north, the water supply pipeline should be insulated and antifreeze treatment.
8. After the construction of the drainage ditch is completed, the plane error between the drainage ditch cover and the ground foundation on both sides of the ditch shall not be greater than 2mm, and the slope requirements shall be met at the same time without affecting the smooth drainage.
The above is the main content of the construction precautions for the drainage ditch of the plastic runway. I hope it will be helpful to your use.
