Definitions

  • the present invention relates to the production of hydraulic works aimed at reducing the risk of flooding.
  • Embodiments described herein relate to modular blocks for producing underground basins for temporarily storing rainwater or river water.
  • the index of occurrence of the flood event obtained by dividing the number of these events occurring over a ten-year period by the total in the same ten years, increases in value over time, reaching substantial numbers (more than double) in the last twenty-five years and have more than quadrupled in the last five years.
  • the block comprises a first plurality of hollow truncated-pyramid shaped bodies, extending from a first side of a median plane of the block, and a second plurality of hollow truncated-pyramid shaped bodies, extending from a second side of the median plane.
  • Each truncated-pyramid shaped body has a larger base on the median plane and a smaller base at a distance from the median plane.
  • the hollow truncated-pyramid shaped bodies are configured and arranged so that identical blocks can be mutually superimposed in two distinct positions, i.e.: in a position with minimum overall dimensions, in which truncated-pyramid shaped bodies of one block are inserted into truncated-pyramid shaped bodies of a superimposed block; and in a second position with maximum overall dimensions, in which truncated-pyramid shaped bodies of two superimposed blocks rest on one another at the respective smaller bases.
  • the truncated-pyramid shaped bodies have on the respective walls, and in particular on the wall defining the smaller base, openings to place the inner volumes of the pyramid shaped bodies of mutually superimposed blocks in fluid communication in the position with maximum overall dimensions.
  • a system for temporarily storing rainwater or river water comprising: an underground basin for temporarily storing rainwater or river water; and at least one hydraulic connection for conveying water into the basin.
  • the storage volume is filled with a plurality of modular blocks of the type defined above, and a covering resting on the filling blocks is formed above the volume of the basin, to form a usable area.
  • a modular block for storage basins for temporarily storing or collecting river water or rainwater is represented in an axonometric view in Fig.1 and in a plan view in Fig.2 .
  • the block 1 is preferably made of molded plastic material.
  • the plastic material can be recycled plastic material.
  • the modular block 1 comprises a first series or plurality of hollow truncated-pyramid shaped bodies 3A, which extends from a median plane with the trace M (see section of Fig.3 ) on one side of this median plane. On the opposite side of the median plane M a second series or plurality of hollow truncated-pyramid shaped bodies 3B extends.
  • the hollow truncated-pyramid shaped bodies 3A, 3B have a quadrangular, and more precisely square, cross section.
  • the truncated-pyramid shaped bodies are arranged in a checkerboard pattern, i.e., alternated.
  • 25 truncated-pyramid shaped bodies 3A are arranged on one side thereof, in rows alternately of three and four truncated-pyramid shaped bodies.
  • the cavities that define the inner volume of the same number of truncated-pyramid shaped bodies 3B that protrude from the opposite side of the median plane M are inserted between them.
  • the total number of truncated-pyramid shaped bodies 3A, 3B is by way of example and it must be understood that modular blocks 1 of different sizes, with a different number of hollow truncated-pyramid shaped bodies, could also be produced.
  • Each hollow truncated-pyramid shaped body 3A, 3B has a larger base lying on the median plane M, and in practice consisting of the opening of the hollow compartment defined inside the hollow truncated-pyramid shaped body 3A, 3B. Moreover, each truncated-pyramid shaped body 3A, 3B has a smaller base, a distance from the median plane M, defined by a closing wall of the hollow truncated-pyramid shaped body 3A, 3B.
  • the smaller bases of the truncated-pyramid shaped bodies 3A, 3B are indicated with 5. Lateral walls 7 defining the sides of each hollow truncated-pyramid shaped body 3A, 3B extend from the larger bases to the smaller bases.
  • each block 1 consists mainly of a layer of shaped plastic material, which forms the lateral walls 7 and the smaller bases 5 of each truncated-pyramid shaped body.
  • the thickness of the lateral walls 7 and of the smaller bases 5 of the hollow bodies 3A, 3B can be approximately constant, for example in the order of 5 mm.
  • the shape and alternated arrangement of the truncated-pyramid shaped bodies 3A, 3B is such as to allow superimposing of blocks 1 in a position with minimum overall dimensions, inserting the truncated-pyramid shaped bodies 3A of one block into the cavities defining the truncated-pyramid shaped bodies of a block above or below. In this way, the blocks 1 interpenetrate allowing a large number of blocks 1 to be stored and transported in a small volume.
  • the blocks 1 can be superimposed in the layout shown in the axonometric view of Fig.4 and in the sections of Figs. 5 and 6 , with the truncated-pyramid shaped bodies 3A of one block placed opposite the truncated-pyramid shaped bodies 3B of a block above or below, arranging truncated-pyramid shaped bodies 3A, 3B in mutual opposition, resting on one another at the respective smaller bases 5.
  • a structure formed by layers of mutually superimposed blocks 1 occupies a very large and mostly empty volume due to the large empty space inside each hollow truncated-pyramid shaped body 3A, 3B.
  • the modular block 1 comprises mutual interlocking elements, associated with the smaller bases 5 of the single truncated-pyramid shaped bodies 3A, 3B.
  • male and female elements are provided on each smaller base 5 of the truncated-pyramid shaped bodies 3A, 3B, destined to engage with one another when two blocks 1 are mounted superimposed in the position with maximum overall dimensions.
  • each smaller base 5 of the hollow truncated-pyramid shaped bodies 3A, 3B comprises a pair of female elements 9 and a pair of male elements 11. These elements are arranged close to the four corners of the smaller base 5 of quadrangular shape. More specifically, the two female elements 9 are arranged closed to two corners along a first diagonal of the smaller base 5 and the male elements 11 are arranged close to the other two corners along the second diagonal of the smaller base 5.
  • the female element 9 is a through opening, which passes through the whole of the thickness of the smaller base 5.
  • the male element 11 consists of a protrusion extending from the smaller base 5 outward.
  • the male element 11 is apertured in 11A and can have a beveled outer edge 11B to facilitate insertion into the corresponding opening 9.
  • the two blocks 1 are stabilized relative to one another and cannot slide laterally.
  • the apertures 11A formed in the male elements 11 form passages that place the inner volumes of the single truncated-pyramid shaped bodies 3A, 3B in mutual fluid communication, for purposes that will be clarified below.
  • reinforcing walls 15 can be provided inside the hollow truncated-pyramid shaped bodies 3A, 3B. As can be seen in particular in Figs.2 and 5 , each wall 15 extends from the inner surface of the smaller base 5 toward the hollow inner volume of the respective truncated-pyramid shaped body.
  • each hollow truncated-pyramid shaped body 3A, 3B there are four walls 15, each of which surrounds one of the openings 9 or one of the passages 11A of the male elements 11.
  • the walls 15 form ribs that increase the crush resistance of the single hollow truncated-pyramid shaped bodies 3A, 3B.
  • the modular blocks 1 it is possible to form layers of blocks, each comprising a plurality of coplanar blocks.
  • the layers can be superimposed on one another so that the modular blocks 1 of each layer are arranged in a position with maximum overall dimensions with the modular blocks 1 of the adjacent layers, arranged with the smaller bases 5 of the single hollow truncated-pyramid shaped bodies resting on one another and with the male and female elements 9, 11 interlocked with one another.
  • the thickness of the walls 5, 7 that define the single hollow truncated-pyramid shaped bodies 3A, 3B, and the elements 11 and the reinforcing walls or ribs 15 can be such that the total volume of plastic is around 1/10 of the total volume occupied by the layers of superimposed modular blocks 1 in the layout with maximum overall dimensions.
  • the modular blocks 1 can thus be used as filling material of an underground, or subterranean, basin I, as shown schematically in Fig.7 .
  • the underground basin I is filled with layers of superimposed modular blocks 1, which rest on a base B forming the bottom of the basin.
  • a covering which can for example be formed of a layer S1 of soil, which forms a useful surface S, is created above the layers of modular blocks 1.
  • the useful surface S can have different uses.
  • the layer S1 formed of soil can form a cultivable area, destined for grazing land, a wooded area, or a public park.
  • the underground basin I can be closed at the top with a material intended to form an area useful for other purposes, for example a car park.
  • the truncated-pyramid shaped structure of the hollow bodies 3A, 3B and the reinforcing walls or ribs 15 give the structure formed by the layers of modular blocks 1 high crush resistance, such that the covering S1 can be formed of even a very thick layer.
  • the layer S1 can be composite, and have a lower substrate S2 in contact with the top layer of modular blocks 1.
  • the substrate S2 can, for example, be created with a material suitable to prevent soil from penetrating the basin filled with the modular blocks 1 below. Similar solutions can be used on the bottom of the basin I, with a substrate S3.
  • the openings 9 and 11A place the single inner volumes of the truncated-pyramid shaped bodies 3A, 3B in fluid communication, so that the water can easily fill the whole of the hollow volume of the hollow truncated-pyramid shaped bodies 3A, 3B.
  • a faster flow of water can be obtained by also producing openings in the lateral walls 7 defining the sides of the hollow truncated-pyramid shaped bodies 3A, 3B.
  • Fig.8 schematically shows the arrangement of an underground basin I, associated with a water course F.
  • the underground basin I can be connected to the water course F by means of one or more hydraulic connections 21, 23.
  • Apparatus to regulate the flow of water into and out of the underground basin I can be arranged along the hydraulic connections 21 and 23.
  • two hydraulic connections are provided, connected to the water course F in two points, one upstream and the other downstream, respectively.
  • water can be diverted from the water course F toward the underground basin I by means of the hydraulic line 21, to reduce the flow rate downstream, and reduce or prevent the risk of flooding.
  • the water temporarily stored in the basin I can be drained away gradually by means of the second hydraulic connection 23 back into the water course F.
  • Suitable bulkheads can be provided in 25 and 27 to regulate water flow.
  • water lifting stations can be provided at the inlet and/or outlet.
  • the use of these lifting stations can be provided as a function of the height at which the entry and exit points of the hydraulic lines are located relative to the basin.
  • a lifting station can be provided on the outflow hydraulic line 23.
  • the basin could be connected to more than two hydraulic lines, for example connected to more than one water course or connected in several points of the same water course, according to specific needs and to the morphology of the territory.
  • each load bearing surface is similar to the opposite one. This result is obtained by mutually intersecting no. 50 hollow truncated-pyramid shaped bodies 3A, 3B (25 on each side of the median plane M).
  • Each modular block 1 has an extremely compact load-bearing structure, capable of distributing the static load. With suitably dimensioning of the modular blocks 1 it is possible to achieve, for example, tensile strengths in the order of 15 tons per square meter without deformations of the modular blocks 1.
  • each modular block can have a weight in the order of 30-35 kg, which makes the block very easy to handle.
  • the filling structure of the underground basin formed by the superimposed layers of modular blocks 1 has a high draining capacity due to the fact that the whole structure is in suitable mutual communication, with wide passages both on the surfaces resting on the ground and on the load-bearing surfaces.
  • the draining capacity can be increased by providing slots or openings (not shown) on the lateral walls 7 of the truncated pyramid shaped bodies 3A, 3B. These slots or openings can be obtained via the mold during the injection molding step.
  • the described modular block 1 allows a plurality of advantages to be obtained, including:
