Definitions
- This invention refers to a method and a device, or system, for laying down and tensioning an impermeable cover comprising sheet material consisting of a plurality of side by side arranged strips of a geomembrane, referred to also as "geostrips", for the protection of hydraulic structures consisting of loose natural material such as, for exam ple, clay, earth, gravel, rocky material and/or their combination, in particular dams, canals, and/or natural and/or artificial water basins, or sim ilar hydraulic structures, by which a blocking and a contemporary controlled stretching of the impermeable cover is achieved during its installation and laying down operations.
- geostrip means an impermeable cover consisting of a plurality of geostrips and/or sheet material sealingly connected to each other along their longitudinal edges, in which each geostrip or sheet includes at least one or more layers of any geosynthetic material as defined below, suitable to be used in contact with the ground; for example, the geostrips sheets could consist of a single layer of a natural or synthetic polymeric resin, or a bituminous material as defined below, or by multiple layers of any geotechnical material, such as a geocomposite consisting for example of an assembled structure comprising an impermeable layer as defined above, coupled with a layer of a geotextile suitable for the intended use.
- a suitable system of canalization obtained by the same anchoring profiles for the geomembrane also allowed for a drainage and evacuation of water that had seeped into the loose material of the body of the hydraulic structure or work, and any water leakages caused by breakages and/or perforation of the protective geomembrane; this prevented the membrane from being subject to bulging and/or high stresses that might have compromised its structural integrity.
- Anchoring systems for geomembrane covers are described for example in EP-A-0 459 015, EP-A-0 722 016 and EP-A-1 137 850.
- US-A-5082397 discloses a method and a device for laying down an impermeable cover comprising a plurality of side by side arranged plastic sheets for protecting hydraulic works, in which the operations of excavating a trench by removing the soil, unrolling and laying down of an unfolded plastic sheet, and immediately ballasting the plastic sheet laid down into the trench by merely covering the same plastic sheet with the previously removed soil, are conjointly made during the excavation, and repeatedly performed during successive passes up to complete an entire region to be protected. Therefore in laying down the plastic sheet, no tensioning is provided, and the formation of folds and/or bags is made possible leading to failure of the sheet material and water infiltration.
- a correct tensioning of the geostrips during the construction and laying down of the impermeable cover is important because it prevents the formation of folds and/or pockets, which, if accidentally perforated, would constitute large, preferential passageways through which water would seep, thus generating all the problems that should be avoided by the use of the impermeable cover; the use of a correctly tensioned geostrips during the construction of the cover can therefore prevent the loss of water through the body of a hydraulic work in loose material, as well as any water seepage and possible subsidence and/or erosion of the same body, and/or of the surface of the hydraulic work in contact with water.
- the object of the present invention is to provide a method and a device suitable for providing an impermeable cover for hydraulic works, in which the impermeable cover comprises a plurality of side by side arranged geostrips in an elastically yieldable synthetic material, and in which the excavation of the trenches, the laying down of the geostrips and the ballasting may be performed by separate steps, allowing an appropriate tensioning of the geostrips to avoid formations of folds and/or bags and water infiltration into the soil.
- a method for laying down and tensioning an impermeable cover comprising a number of geostrips in an elastically yielding synthetic material, on a surface of a hydraulic work in loose material comprising the steps of:
- a device suitable for laying down and tensioning an impermeable cover for the soil surface of a hydraulic work in loose material, according to the method of claim 1 , in which the impermeable cover comprises a plurality of side by side arranged geostrips in elastical ly yieldable synthetic material , having overlapped side edges, and in which the geostrips are held by a ballasting material in a plurality of trenches parallely extending on the hydraulic work surface, characterised by comprising:
- said plurality of trenches comprising a first set of alternate trenches, and a second set of alternate trenches, in which each trench of the first set is extending between trenches of the second set of trenches;
- the individual trenches can be directly shaped with a regularly, finished surface to come in contact with the geostrips, consisting of the same inert material of the soil; otherwise if the soil surface where the trenches are excavated or dug includes rocky material, gravel and/or aggregates of larger dimensions, it is possible to provide the trenches with a first bottom layer consisting of inert material of suitable granulometry and consistency, for example gravel and overlaying the bottom layer with a second layer of fine-grained filtering material such as sand, clay and/or slime that is then shaped to provide trenches having a longitudinal cavity with a regularly, finished surface suitable to come in contact with the geostrips.
- the filling of the trenches with fine-grained material and the shaping of the contact surface are required in soils having a granulometry higher than the sand which, during digging or excavation would not allow smooth and regular shaping of the trenches. Any improper shaping of the trenches will result in an improper positioning and tensioning of the geostrips which would lie on the edges of the trenches along irregular lines, thus giving rise to a cover being lain with wavy edges, which would make it difficult, if not impossible, to weld the overlapped edges of the geostrips, causing folds and/or bags that would reduce the tensioning effect.
- the filling of the trenches with a loose ballasting material also allows a secondary drainage and filtration function. The presence of layers of drainage and filtering material can be limited to the trenches alone, or extend over the entire surface of the hydraulic work to be covered by the geostrips.
- the presence of a filtering and drainage layer thus allows any water leakage through the covering geostrips to be collected, and to relieve any negative pressures acting on the cover, arising from the presence of water, such as ground water, on the back side.
- the geostrips can be transversely laid over the trenches and then sealingly connected to each other along their overlapped edges, or they can be pre- welded and longitudinally laid down on the trenches, provided that the total width of the geostrips or sheets of pre-welded geostrips is higher than the width between the extreme edges of three or more adjacent trenches.

- Fig. 15 is a schematic view, summarizing the main steps of the method according to the invention.
- Figure 1 shows, for example, a generic hydraulic work consisting of loose material, comprising a water basin 10 including an embankment 1 1 having a sloped inner surface 12, and a bottom surface 1 3 for holding a certain quantity of water.
- both the inner surface 12 and the bottom surface 13 of the water basin are usually protected by an impermeable cover consisting of a geomembrane comprising a plurality of geostrips of a synthetic elastically yielding elastomeric material, which must be properly sealed together along their overlapped edges, tensioned and anchored to the ground.
- an impermeable cover consisting of a geomembrane comprising a plurality of geostrips of a synthetic elastically yielding elastomeric material, which must be properly sealed together along their overlapped edges, tensioned and anchored to the ground.
- Any material can be used for the geostrips of the im permeable cover, provided that it is suitable for its intended purpose; in particular it can be chosen from among the synthetic materials listed in the following table, taken individually or in combination.
- the geostrips can vary in thickness between 0.2 and 40 mm, with an elastic modulus between 10 and 5,000 MPa, possibly coupled with a geotextile.
- a plurality of trenches 14 are initially excavated into the soil, parallel to one another and all oriented in a given direction; the trenches 14 must be large enough to accommodate, if necessary, a preset quantity of drainage material and/or filtering material, as explained below.
- the trenches 14 can be of any suitable shape, for example they can have a rectangular, trapezoidal or semicircular cross section.
- the trenches 14 can be of any width L at the upper edges, and a depth S depending on the nature of the soil and the amount of drainage and/or filtering material in the trenches, while the pitch P between adjacent trenches 14 must be much larger than the width L, for example, between four and ten times L, or higher, so that between adjacent trenches 14 there will be a length of geostrips sufficient to allow for an required elongation by the elastic yielding, needed for tensioning by a suitable ballasting material.
- trenches having a maximum width L between 600 and 1000 mm, and a depth D between 400 and 700 mm were excavated, maintaining a pitch P between 4 and 10 m.
- the soil is composed of inert material of fine size particles, equal to or less than 0.5 to 0.6 mm, such as sand or clay, once the trenches 14 have been excavated, the soil must be adequately compacted, shaping the individual trenches with a longitudinal cavity having a regular, finished contact surface, suitable to come in contact with the geostrips 14.
- the individual trenches are partially filled 14 with a first layer 15 of drainage material, consisting for example of large-sized gravel; in this way a sort of drainage canal is provided, suitably slanted toward a peripheral manifold.
- a first layer 15 of drainage material consisting for example of large-sized gravel
- the layer 15 of drainage material can be distributed in the trenches 14 on the bottom surface 13 of the hydraulic work, or water basin 10 alone, while in the case of a sloped surface 12, facing towards the water in the basin 10, it is suggested that the drainage layer 15 be laid over the entire surface, as schematically shown in Figure 5.
- the layer 1 5 of drainage material in the trenches 14 will be distributed so as to form a longitudinal cavity 16 large enough to hold a second layer 17 of filtering material, as shown in Figure 6, in particular loose, shapeable material, such as earth, fine sand or small-sized gravel, rounded and sharp edges, which thus becomes a transition layer between the underlying drainage layer 15 and the protective geostrips subsequently laid down.
- a longitudinal canal 18 is provided as shown in Figure 6.
- the thicknesses of the drainage layer 15, the filtering layer 17, and consequently the shape and size of the longitudinal canal 18, must be calculated so that the canals 18 can accommodate geostrips large enough to cause a desired tensioning, as well as to ensure the necessary blocking to withstand external forces such as wind, wave motion and ice.
- the cover is built by laying down a number of geostrips 20 transversely or orthogonally across the trenches 14, as shown in Figure 7, unwinding them from rolls; as an alternative to laying down the geostrips transversely 20, as shown in Figure 7 multiple pre-welded geostrips 20 can be laid down, parallel to the trenches 14, provided that the total width of the pre-welded geostrips is greater than the space between the extreme edges of at least three adjacent trenches 14.
- the geostrips 20 are initially laid down and unfolded in a flat condition adhering to the soil or a surface of the hydraulic work to be protected, a bridging across the individual trenches 14, as shown in Figure 8; providing for a suitable overlap 21 between the opposite edges of adjacent geostrips, it's possible to achieve a sealing connection between them, for example by thermal welding, vulcanization or a suitable adhesive.
- their anchoring and tensioning should proceed; this is done gradually in successive steps, as shown in Figures 9 to 14 of the attached drawings.
- the geostrips 20 are first sequentially pushed into the cavities 18 of a first set of alternate trenches 14A, for example the odd-numbered trenches as indicated by the reference numbers 1 and 3 in Figure 9, by a first appropriate ballasting material 22. More precisely, in ballasting the geostrips 20 into the first set of alternate trenches 14A, the geostrips 20 remain adherent to the soil with an arrangement bridging the remaining second set of even-numbered trenches 14B, adjacent to and interposed between the previous set of trenches 14A, as indicated in Figures 9, 10 and in detail in Figure 12.
- the geostrips are then tensioned and ballasted into the cavities of the even-numbered trenches 14B, as shown and indicated by 22A in Figures 13 and 14.
- ballasting material 22 and 22A can be used; for example, it can be selected from among the following: gravel, sand, earth, concrete, or a combination thereof.
- ballasting material 22, 22A can be covered with an auxiliary geostrip 23, longitudinally extending over the individual trenches, heat-sealed along the edges to the geostrips 20.
- the geostrips 20 and 23 can be of any type, for example, them may be in the form of simple strips of geosynthetic material, or a geocomposite consisting of a combination of geosynthetic and geotextile materials.
- the transition layer may include a geotextile, a geocomposite, a geonet or other anti-perforation material suitable for the protection of the geostrips; likewise the drainage layer may consist of any geodrainage material such as gravel, geonet, geogrid, geomat or combination thereof.
- Figure 15 gives an explanatory summary of the main steps from S1 to S5 of the method for laying down and tensioning the geostrips according to this invention, in particular:
- S3 shows the step of filling the trenches 14 with an optional filtering layer 17, shaped with a longitudinal cavity 18 suitable to provide a regular, finished surface to come in contact with the geostrips.
- S4 shows the laying down of the geostrips 20 bridging across the trenches 14;
- S5 shows the pushing and blocking step of the geostrips by a first ballasting material, in the cavities of a first set of trenches such as the odd- numbered trenches 14A;
- S6 shows the final step tensioning and anchoring the geostrips, pushing and blocking them into the cavities of the remaining second set of trenches such as even-numbered trenches 14B by a second ballasting material.
