Use of expanded polystyrene EPS in Hydraulic Projects
In addition to civil engineering, the use of expanded polystyrene EPS has extended to the hydraulic sector. The most common applications in this line are the following:
The docks of the yacht ports, for example, are usually made of wood. The problem here is not only the supported structures at the ends, so that the wood of the springs and necessary piles have to be heavy, but also that the wood in these cases is also subject to rot, especially in the line of a water surface.
However, using EPS expanded polystyrene blocks for a floating, moisture-insensitive foundation you can work with a very small proportion of wood. The expanded polystyrene EPS floats in the water and supports the dock at all construction sites.
It is also possible to build a spring with expanded polystyrene EPS capable of moving up and down as the water level changes. In addition, changing the arrangement of the piles is a simple job and their shortening or lengthening can be done easily and cheaply.
The thickness of the polystyrene to be used depends on the maximum number of people expected to have to support the spring.
A recreational islet of several thousand square meters can be installed quite easily on EPS. Normally, a layer of several tens of centimetres of expanded polystyrene EPS is sufficient to withstand the full weight of the islet including vegetation, people and buildings.
Plates of drainage of expanded polystyrene EPS may also ensure proper drainage of rain water during rainy weather and a good supply of water during dry weather.
The blocks and plates are encolated “on the ground”, reinforced and placed perpendicularly on top of each other. After a final treatment with PUR foam and its hardening, the bare islet is pushed into the water by a excavator shovel.
The visible layer and the earth retention layer are then installed according to the various possible structures.
The anchoring of the islet is carried out with the help of wooden tubes through which they are nailed, by Hammers, wooden or concrete piles, or the piles are placed at the depth due by means of a propulsion tube. Therefore, the vertical movement of the islet due to changes in the water level can be absorbed without any problems. The soil and vegetation are then installed on the islet.
A recreational Islet on expanded polystyrene EPS can not only be built very quickly, but also costs much less than building an islet in the traditional way. On the other hand, there is nothing definite about the structure and the islet can simply move.
