Description

 Three-layer permeable elastic packing material and construction method {Three-layered permeable type Elasticity Paving Material and Constructing Method of Julia}

The present invention relates to a three-stage permeable elastic packaging material and its construction method.

In general, the elastic packaging material is applied to the floor of the facility with high activity such as play or sports activities such as apartment walkway, bicycle path, plaza, golf course path, jogging track, walkway, various sports facilities or playroom, playground It protects the joints during walking or exercise of children or the elderly, and installs to prevent injury by absorbing the amount of impact generated when touching the floor by activities.

As such, the elastic packaging material is to be installed on the top of the ground by mixing an elastic material, such as urethane, an elastic material with a binder, looking at with reference to FIG.

It is constructed by constructing the elastic layer 2 in which the urethane chip and the binder are mixed on the ground in the state where the ground 1 is chopped.

As described above, the conventional method for constructing an elastic packaging material has a problem in that the service life is reduced as the elastic layer is displaced and damaged due to the change or settlement of the crust due to the weakening of the ground as it is directly installed on the upper part of the ground.

In addition, the conventional method for constructing an elastic packaging material is to apply urethane chips formed in the chip form to form urethane chips to form an elastic layer on the ground with a binder for attaching urethane. The adhesive force of the binder decreases with time, and thus the urethane chip is continuously removed. As a result, there was a problem that the life is reduced.
