Definitions
- the present invention relates to a lightweight backfill and more particularly to the technique of construction of such an embankment.
- the object of the invention is to provide lightweight economic embankments and requiring little building materials, while having properties of improved stability.
- the invention relates to a light backfill according to the claim 1.
- the light backfill according to the invention may include one or more characteristics described in claims 2 to 18.
- the embankment 1 shown in Figure 1 is intended to support a roadway. Its width gradually decreases from its base towards its Mountain peak.
- the embankment 1 is constructed from building blocks 3 of elongated parallelepiped shape, stacked in successive layers on the others, the blocks 3 of the same layer being arranged in rows parallel.
- the first layer of backfill, base layer 5, rests on a bed 6 of quarry sand or crushed material, of approximately 0.1m thick on average.
- the blocks 3 of the other layers are laid with crossed with respect to blocks 3 of the adjacent lower layer.
- the blocks 3 of each layer are separated from each other. by free spaces 7.
- the width of free spaces 7 is constant and less than 1m, and preferably between 0.2m and 0.6m.
- the width of the free spaces of the lower layers may be greater than that of the open spaces of the upper layers.
- the cover layer 9 is however formed by blocks 3 placed contiguously to carry a reinforced concrete slab 11 supporting the wearing course 13 of the road.
- the height of the blocks 3 is between 0.17m and 1.1m.
- the blocks belonging to the same layer all have the same height. In the example shown, this height is uniform for all the embankment, but, alternatively, this may vary from layer to layer.
- the blocks 3 are made of light plastic material, in particular of expanded polystyrene.
- Light plastic material means a plastic material with a density less than 1000 kg / m 3 .
- the density of the material used is greater than 21 kg / m 3 , in particular greater than 23 kg / m 3 , and the compressive strength at 10% crushing is greater at 110 kPa, in particular greater than 130 kPa.
- the total weight of the structure remains approximately the same thanks to the free spaces between the blocks of a layer.
- At least one end, and preferably all the ends, of the free spaces 7 are closed by end caps 16 made of the same material as blocks 3, or by a geotextile membrane.
- At least some of the blocks 3 are provided with construction, during stacking, of joining means, for example those shown in Figure 2.
- These joining means are formed by at least a rod 17, and preferably by two rods 17.
- These are in particular vertical steel rods, longer than height of an associated building block 3, which pierce this block respectively near its ends and protrude on either side of the block.
- the parts protruding rods 17 are intended to sink into blocks of two adjacent layers and thus secure the blocks against lateral displacement.
- rods with a diameter of 8mm and a length are used 1.10m.
- Figure 3 shows a light embankment 1 to be built against an inclined slope 19.
- the laying bed 6 is here made of materials crushed with an average thickness of 0.15 m.
- elements corresponding to those of figure 1 will be identified by the numbers correspondents.
- This variant differs essentially from the embankment shown in Figure 1 by the fact that there are provided holding elements 21 of the embankment housed in certain free spaces 7 of the embankment 1.
- such a holding element 21 is produced in pouring concrete into a free space 7 forming lost formwork.
- the ends of the free space as well as the openings thereof which communicate with the free spaces of the lower layers are closed by plates, or alternatively, with regard to the ends of the spaces free, by blocks 22 of cut expanded polystyrene which are flush with the free surface of the embankment.
- Another solution could be to carry out the fillings in question using geotextile membranes.
- the elements holding 21 are preferably cast in a free space having a width less than 0.3m of a layer formed by blocks having a height less than 0.3m, so as not to make the embankment too heavy.
- this anchoring element 23 is also formed by poured concrete, together with the concrete forming elements of maintenance 21, in a free interval provided between the slope 19 and the embankment 1.
- the end 25 of the free space 7 forming lost formwork, opposite slope 19, is widened.
- the concrete poured into this the enlarged end thus forms a retaining element 26 having a shape in T.
- a light backfill 1 with free spaces 7 allows a considerable savings in the volume of material used for construction and, as a result, savings of around 20% in transport costs.
- Another advantage of the lightened backfill according to the invention relates to drainage thereof, especially when it is built on land flood.
- water enters, through the bed laying 6, in the free spaces 7 of the base layer 5, which communicate with free spaces 7 of the upper layers.
- the free spaces 7 of the different layers are gradually filled with water.
- Archimedes' push exerted over the entire embankment is reduced, so that the stability of the embankment 1 is only slightly affected by the flood.
- the layers can be formed blocks of SAUL material.
