400m standard plastic track data calculation method, therefore, to each runway perimeter is calculated as follows: a 87 × 2 + 2 × 3.14 × (36 + 1.2 × 0) = 400 two 87 × 2 + 2 × 3.14 × (36 + 1.2 × 1) ≈408 three 87 × 2 + 2 × 3.14 × (36 + 1.2 × 2) = 415 four 87 × 2 + 2 × 3.14 × (36 + 1.2 × 3) ≈423 m five 87 × 2 + 2 × 3.14 × (36 + 1.2 × 4) ≈430 m six 87 × 2 + 2 × 3.14 × (36 + 1.2 × 5) ≈438 m seven 87 × 2 + 2 × 3.14 × (36 + 1.2 × 6) ≈445 m eight 87 × 2 + 2 × 3.14 × (36 + 1.2 × 7) ≈453 m can be calculated based on the above data the 800m, 1000m basketball court, 1500m, 3000m >>>> starting point, such as a basketball court built, everything is only one end of the final project that the end of the straights. Above is for reference only learn objections can explore together. Prefabricated plastic runway prefabricated plastic runway silicon basketball courts, a sports ground or track, especially a plain structure with prefabricated plastic runway. It contains a friction surface layer, shock-absorbing layer and the shock-absorbing layer disposed between the adhesive layer and the foundation of its features are: its shock-absorbing layer is a solid sheet of plain structure. After the utility model of prefabricated plastic runway in the shock-absorbing layer with a plain sheet-type structure, can complete bond between the shock-absorbing layer and the base, the adhesive surface is 100%, so not only can ensure that it has the traditional prefabricated plastic runway should the use of functions, but also to prevent sequestration of air or volatile components such as the shock-absorbing layer of the runway, which can effectively prevent the emergence of a runway in use or at high temperatures from the dark, off layer, even if the use of prefabricated plastic runway reliable, and reduce maintenance problems, and thus also significantly prolong life.
