Small retention systems - an important element of flood and drought management in forest ecosystems.
The analyses conducted during the past fifty years have clearly shown that more and more regions will suffer from periodical water scarcity. Due to global climate change, unfavorable trends in the existing water balance were diagnosed in many areas, i.e. lowering of the ground water level and the water surface level in reservoirs, disappearance of forest lakes, drying out of the naturally damp forest ecosystems and the progressive degradation of peat soils. The vinyl small retention sluice gates offered by ESC are an advanced, durable and easy to maintain alternative to the traditional, wooden small retention systems. It is also an environmentally-friendly solution due to the use of recycled PVC construction components, with the possibility of re-processing.
The small retention sluice gates are made from tough polyvinyl chloride, modified with refining agents (e.g. toughness modifiers, UV and thermal stabilizers and mineral filling components). Thanks to the use of this closed-cycle recycling method, vinyl sheet piles are an envionmentally friendly solution. Application of the ISO 9001:2008 standard has enabled ESC to provide and maintain high-quality products.
Five reasons to choose the small retention sluice gates manufactured by Pletrucha ESC.
- Easy to handle and maintain with light-weight mobile elements.
- Do not require maintenance works.
- Fast assembly using light equipment.
- Natural look in harmony with the surroundings.
- Highly resistant to the impact of mechanical, atmospheric and biological factors.
The small retention sluice gate system is made of tubular profiles in the shape of a honeycomb. This profile design guarantees high strength and at the same time lightweight transport and easy assembly in hard access spots. The profiles are connected with locks equipped with valves which guarantee 100% water -tightness of the construction. The smooth surface of the walls may be extruded in the form of a tree ring pattern to perfectly melt with the surrounding environment. When the water level rises, the PVC tubular profiles assembled diagonally fill in with water. The weight of the water inside the profiles makes the locks fit tightly to create water-resistant sluice.
