AI Technical Summary

Technical Problem

Existing plastic running tracks are prone to cracking due to temperature changes during seasons with large temperature differences between day and night, and the drainage holes are easily blocked by debris, affecting drainage efficiency and safety.

Method used

Design a crack-resistant precast running track that employs a funnel-shaped drainage ditch, a filter screen, and a multi-layer structure, including an upper surface layer, a base layer, a drainage ditch, a reinforced concrete precast cover slab, a filter screen, a drainage layer, and a waterproof layer. It utilizes gravity to accelerate drainage and prevent debris from entering, and combines a fiberglass crack-resistant mesh and an elastic buffer layer to reduce the risk of cracking.

Benefits of technology

It effectively prevents runway cracking, improves drainage efficiency, reduces the risk of blockage, and ensures that the runway remains safe and comfortable to use when it is flooded during rainy weather.

Abstract

The utility model discloses a prefabricated runway of anti -cracking belongs to the field of playground, including filter screen, filter screen detachable setting at the mouth of drain ditch, the groove of drain ditch is the funnel -shaped structure of narrow upper wide lower, the utility model discloses a prefabricated runway of anti -cracking, when the rainwater, the ponding will flow into the groove from the mouth of drain ditch, because the design of drain ditch is funnel -shaped structure, the top aperture is greater than the bottom aperture, utilize gravity acceleration drainage and reduce the risk of jam. And filter screen can prevent sundries from entering drain ditch. Filter screen adopts stainless steel screen or water -permeable non -woven fabric to make. When filter screen is stainless steel screen, the mouth of drain ditch is equipped with the mounting groove, can install the filter screen in the mounting groove and install, when filter screen is water -permeable non -woven fabric, the mouth of drain ditch is equipped with a plurality of hooks, can hang filter screen in the hook.
