About This Product
■Summary
In the late 1975s, Ozawa Concrete Industries Co., Ltd. (currently Materas Ome Industries Co., Ltd.) developed permeable Polacon with the idea of suppressing the runoff of rainwater, which is the source of urban flooding. Subsequently, based on the Ministry of Construction's construction technology evaluation regulations, the facility was evaluated as a ``infiltration-type runoff control facility that fully utilizes the infiltration capacity of the ground and is highly durable against clogging'' (Kengihyo No. 87301). As a result, it has achieved many successes as a spill control facility to this day.
Furthermore, the concept of mitigation, which aims to compensate for the loss of the natural environment due to development by creating a qualitatively and quantitatively equivalent natural environment, has become increasingly important. For this reason, storage and infiltration type Polacon facilities are being installed in a wide range of projects, from comprehensive river flood control measures and sewage outflow control measures to environmentally harmonious urban development.
■Features
1. Porous concrete with uniform and continuous voids.
2. The amount of penetration is large and the amount of storage can be secured.
3. Not blocked by replacement material.
4. Less clogging.
■Summary of rainwater infiltration/storage infiltration method
When rainwater infiltration decreases due to urbanization, it increases flood flow from a disaster prevention perspective, and from an environmental standpoint, river pollution progresses due to a decrease in spring water. The rainwater infiltration/storage infiltration method is a method that restores rainwater to its natural cycle as much as possible, and provides flood protection and environmental protection functions for each basin or area.
Runoff control facilities can be roughly divided into rainwater infiltration/storage/infiltration construction methods combined type and rainwater storage type. However, considering the occupied area in urban areas and the preservation of the overall water environment, the rainwater infiltration/storage infiltration construction method combination type is recommended. superiority is recognized.
■Applications of rainwater infiltration/storage infiltration method
1. Recharging groundwater and securing water resources.
2. Clearing flooded areas and preventing river pollution.
3. Prevention of decrease in river flow rate and pollution prevention during normal times.
4. Prevention of ground subsidence.
5. Preventing vegetation depletion.
6. Prevention of salinization by reverse osmosis of seawater.
7. Preventing the expansion of the land and water treatment facilities on the premises.
