Sponge foundation technology
Compared with the traditional cement foundation and asphalt foundation, the sponge foundation has three times of the traditional drainage speed, 30% higher damping effect than the traditional grassland, the filling material loss rate is one third of the traditional grassland, low cost and short construction period.
The project has applied for patent and has mature process technology and production capacity for market promotion.
The basic craft of stone powder sponge is now used in many venues: Huangpu Tree-planting Park, Heimei Football Park, Zhujiang New Town Football Park.
The foundation of stone powder sponge successively includes the first soil layer, gravel layer, geotextile isolation layer, stable layer and artificial lawn.The laying method of the stone powder sponge foundation is implemented in the following steps: in the site selection area, the ground shall remove weeds, and the plain soil shall be compacted with a roller to form a plain soil layer;Then lay a drainage blind pipe with a transverse spacing of 10 meters, and lay gravel with a thickness of 15cm on the compacted plain soil, which is then compacted by a roller to form gravel layer.Cover geotextile on gravel layer to form geotextile isolation layer;On the isolation layer of geotextile, a 15-30cm stable material made of cement and stone powder is laid to form a stable layer.After the stable layer solidifies;Finally, the artificial lawn can be laid to form a sponge football field.
To be sure, technology has provided us with more and better choices, and this foundation will become the mainstream of domestic sports venues in the future.
