Definitions
- the invention relates to a fire barrier with attachable to form a protective strip or a protective surface on the ground and with insertable through eyelets, e.g. Tent hooks, attachable tarpaulins made of fire-retardant material.
- eyelets e.g. Tent hooks, attachable tarpaulins made of fire-retardant material.
- a known fire barrier of the type mentioned is the subject of WO 96/05887 A.
- tarpaulins that are not made of incombustible or fire-resistant material are used, but the material of which is highly absorbent. This results in the need to carry out an intensive impregnation of the tarpaulins, which are simply strung together on the ground, with water in order to achieve an actual protective effect, with water of the order of magnitude being 26 l / m 3 . Only when this water is filled does the tarpaulin lie on the floor, which is at least partially covered with flammable material, with a sufficient protective effect.
- Fire barriers are actually used, particularly in forest areas, in which a strip-shaped protection zone with a width of about 2 - 3 m is cleared and then a protective trench is usually excavated by hand in the clearing area, with the excavated material being used to create ramparts at the edges of the trench. It is important to ensure that no flammable sections protrude from this excavated material.
- a central trench having the corresponding width is dug, which is flanked by two narrower, further protective trenches while maintaining shorter safety distances.
- the central trench is filled with the excavated material that has been turned and largely freed of combustible residues to form a double dam that is flanked by the narrower protective trenches.
- the central trench remains empty and the protective dams are built in and over the narrower protective trenches.
- the achievable protective effect depends on the fact that neither the central trench nor the dams actually contain combustible material or that no dry root material or the like is contained in the empty trenches.
- the object of the invention is therefore to provide an effective fire barrier of the type mentioned, which can be built with a low weight of the tarpaulin used without additional water supply with relatively little effort.
- the tarpaulins are made of tear-resistant aluminum, laid with their adjacent edges overlapping, inserted with their edge facing the fire side into a raised soil furrow, additionally fastened there and covered with non-combustible material, at least one of which Part of the excavated material is formed on the other edge of the furrow an additional protective dam.
- a tarpaulin which is very light in weight and which only has the necessary tensile strength can be used find, assuming that the engagement of the fire-side tarpaulin edge in the soil furrow and the appropriate cover ensures sufficient security against the passage of fire and embers into the other covered area.
- the purpose of covering this area is therefore essentially to intercept burning parts, such as inflamed tufts of dry grass, pieces of branch, etc., without igniting areas behind the barrier.
- the effect of the lock can be increased by spraying it with water if water is available.
- the protective dam which is known per se, also weakens an approaching flame front before it reaches the soil furrow.
- the surface of the tarpaulin should preferably be smooth and reflect well. In addition, it is favorable if the tarpaulin is accessible.
- the tarpaulins preferably consist of aluminum foil, woven fabric, knitted fabric or a composite material made from these elements.
- a continuous serpentine cushion is provided to cover the tarpaulin edge protruding into the furrow, which accommodates a filling of sand and / or excavated earth material in an aluminum shell, preferably in several chambers.
- the accommodation of the cushioning material in the aluminum shell reliably prevents that even flammable residues can ignite when the excavation material is used for the filling, and additional protection of the tarpaulin edge most exposed to a flame front is guaranteed.
- Forming the cushion with several chambers increases the desired security.
- the chambers of the serpentine cushion preferably have the shape of a pointed parallelogram, because this gives an optimal distribution of the filling material and the pressure distribution, which serves for sealing.
- the chambers can, particularly when filled with sand, be provided with Velcro fasteners or zippers, which preferably also consist of aluminum and effectively prevent the filling from escaping.
- the tarpaulins used for the fire barrier can also be used for other purposes.
- a new application proposed according to the invention consists in Use of the tarpaulins for shading and for the formation of sand and dust barriers in dry or desert areas with the proviso that the tarpaulins are attached essentially vertically to supports, for example aluminum piles, and their lower edges are anchored to the ground.
- Some rows of long tarpaulin walls can be erected at intervals, preferably normal to the prevailing wind directions, for example in a north-south direction, so that they initially prevent the sand migrating in desert areas near the ground from advancing further in the wind direction.
- the tarpaulin walls result in partial shading of the adjoining soil areas, which, together with the blocking of near-surface wind and air currents, reduces the otherwise existing drying of the soil and thus encourages plant growth.
- the tarpaulins are attached to the supports with additional suspension of their upper edges on the cables connecting the supports.
- the supports can be anchored in the floor using a rectangular concrete block, for example, which has a hole for the supports and is buried in the floor.
- the supports can also be anchored deep in the ground with a sword, preferably made of aluminum. It must be ensured that the sword is firmly screwed to the support by means of a plug device.
- the sword can also have the shape of a wave, which results in better wind protection due to the better anchorage in the ground.
- the distances between the tarpaulin walls are to be selected, for example, depending on the annual temperature, the nature of the soil and the size of existing plants.
- the distance between the tarpaulin walls is usually between 3 and 7 m, but can also be higher.
- the height of the tarpaulin walls is preferably between 2.5 and 3 m.
- a fire barrier according to the invention is schematically illustrated as an exemplary embodiment, partly in section and partly in the diagram.
- a soil furrow 1 is first excavated in a protective strip and a protective dam 2 is erected from the material on the edge of the soil furrow 1 facing the fire source or the flame front to be expected.
- tarpaulin 3 made of aluminum material are laid in such a way that their front edges 4 the rear Overlap the side edge of the soil furrow 1 and also overlap the adjacent side edges 5 of the tarpaulin 3.
- the tarpaulins 3 are equipped with eyelets 6 along their circumference, through which fastening means, for example tent hooks 7, can be inserted.
- a cushion 8 is attached, which is formed in a serpentine shape and accommodates a sand filling 9 in an aluminum shell, which is optionally divided into several individual chambers.
- tarpaulin 3 for shading or as a sand and dust barrier
- tarpaulins with a good reflectivity of the surfaces should be used.
