    [0002] Urban drainage system
    [0004] Technical field of the invention
    [0006] The present invention corresponds to the technical field of urban sustainable drainage systems whose objective is to mitigate the impact of impermeability in urban areas, facilitate stormwater runoff, retention and attenuation of peak flows, delay the response of the basin, slow down the speeds of water and increase the accumulation time of the same.
    [0008] Background of the Invention
    [0010] Today and since the 1950s, the total area of cities in the EU has increased by 78%, while the population has only grown by 33%. These data require a rethinking of soil treatment in cities due to the enormous environmental impact generated by the increase in paved areas or “soil sealing”.
    [0012] This increase in paved areas in cities causes an increase in the temperature of the environment caused by the lack of evapotranspiration of the soil (“heat island” effect), floods associated with the increasing volume of rainwater, restriction in gas exchange between the soil and the atmosphere causing an increase in pollution and greater health risks, among other serious consequences.
    [0014] Likewise, the warning of various authors who predict an increase in rainfall intensities by up to 60% by the year 2100 must be taken into account, a fact that combined with the aforementioned increase in paved areas generates a problem to be taken into account and whose The solution must be considered in the sense of developing new strategies that manage to limit, mitigate or compensate the sealing of the soil.
    [0016] In this context, Sustainable Urban Drainage Systems (SUDS), also known as Water Sensitive Urban Design (WSUD), are being developed as a sustainable alternative for rainwater management.
    [0017] The objective of these systems is to mitigate the impact of impermeability in urban areas, facilitate stormwater runoff, retention and attenuation of peak flows, infiltration and small-scale evapotranspiration processes, reduce discharged volumes, delay the basin response, slowing flow velocities and increasing water accumulation time.
    [0019] There are different types of SUDS techniques, classified into control systems at source, transport and storage or passive treatment. Control systems at source (green roofs, permeable surfaces, infiltration wells and ditches and bioretention gardens) solve the problem in the place where the rain falls, allowing its infiltration.
    [0021] On the other hand, transport systems (filtering or French drains, filter strips or green gutters) are those devices that transport rainwater to other major treatment systems or to the receiving environment.
    [0023] Finally, passive storage and treatment systems (infiltration tanks, retention ponds or artificial wetlands) are located at the end of the network to extend the stay of rainwater for its use or retention before discharge.
    [0025] Currently, the most effective SUDS for immediate water evacuation, both horizontally and vertically, are a system of cells made of recycled polypropylene. From their union they allow their application horizontally as a draining blanket, vertically as a draining wall or by means of a grouping of the same for the storage or channeling of water.
    [0027] These systems have been widely accepted, given that they have a percentage of voids much higher than that of the most commonly used granular systems, but they present a significant limitation in terms of the loads they can withstand.
    [0029] With these systems, if a typical cobblestone surface finish is laid with a bed of granular material, the maximum loads that are supported are 3 tons, which limits its use to areas with light traffic.
    [0030] The commercial brands of these plastic products propose solutions where higher loads can be supported, in which they propose the realization of reinforced concrete slabs and large layers on the material, but they are economically unfeasible solutions.
    [0032] In addition, technically they do not make much sense, since large amounts of material (granular and reinforced concrete) would have to be placed to support loads, so the possible advantage obtained by a higher content of voids compared to granular layers, is lost by having to use large amounts of materials that are more expensive and polluting than a granular layer (reinforced concrete slab).
    [0034] There is no known existence in the state of the art of any sustainable drainage product that presents a high percentage of voids to allow the infiltration of rainwater, such as plastic systems, and that also has a sufficient resistance to withstand the damage. passage of all categories of existing traffic.
    [0036] Description of the invention
    [0038] The urban drainage system presented here comprises at least one underground rainwater collection structure with a longitudinal configuration with two opposite ends thereof and is formed by at least one concrete module in the shape of a portico.
    [0040] Each of these modules comprises an upper slab, a first and a second support thereof, formed by walls of a width equal to the length of said slab and means of access for water to the interior space of the module arranged at the junction of the slab with the second support.
    [0042] On the other hand, the first support of the module has a greater height than that of the second support so that the slab presents an inclination towards said second support.
    [0044] The system thus defined further comprises means of outlet for the collected water.
    [0046] With the urban drainage system proposed here, a significant improvement in the state of the art is obtained.
    [0047] This is so because a system capable of acting as a reservoir or as an underground channel is achieved to store and control rainwater runoff from impervious surfaces such as parking areas, roads ...
    [0049] With the system proposed here, a reduction in the volume of runoff, an attenuation of the peak flow, protection of existing water masses, reuse and exploitation of water resources, flood risk management, protection of the receiving environment and provision of resilience to the system is achieved. in the face of future events.
    [0051] Likewise, a modification of the traditional waterproofing design is achieved through the creation of temporary storage spaces for the runoff generated in adjacent impervious areas, enabling the capture, filtration, retention, transport, storage, infiltration and reuse of the water resource.
    [0053] All these are the objective characteristics in any urban drainage system, but in this case, in addition to all of them, the system has the ability to withstand high traffic loads from the highly durable prefabricated modules used to obtain it. .
    [0055] Thus, with these precast concrete modules with high storage capacity, it is possible to withstand the passage of road traffic, positioning itself as a preventive and mitigation measure in the face of the problems mentioned, with the aim of preventing risk situations that cause extreme phenomena by managing the risk associated with the occurrence of these events.
    [0057] In addition, these are systems that use concrete modules, eliminating the use of plastic, this being a beneficial aspect aimed at protecting the environment.
    [0059] It is also possible to channel the water resource before its reuse (irrigation, flushing streets, etc.), infiltration to the ground to recharge the aquifers and / or discharge to the network, after controlling the necessary parameters. And all this while minimizing the cost of drainage infrastructures.
    [0061] It is therefore a very effective system, which allows its use in any area, especially in those that need it most, such as road areas, thanks to the fact that they are able to withstand traffic loads.
    [0062] Brief description of the drawings

    [0074] Figure 5.- Shows a schematic sectional view of an urban drainage system, for a preferred embodiment of the invention.
    [0076] Detailed description of a preferred embodiment of the invention
    [0078] In view of the figures provided, it can be seen how in a preferred embodiment of the invention, the urban drainage system (1) proposed here comprises at least one underground rainwater collection structure (2) of longitudinal configuration with two opposite ends (10) thereof and is formed by at least one concrete module (3) in the form of a gantry, and means of outlet for the collected water.
    [0080] In this preferred embodiment of the invention, as shown in Figures 3, 4 and 5, the system comprises two adjacent structures (2), each of which is made up of several consecutive modules (3).
    [0081] As shown in Figure 1, each of these modules (3) comprises an upper slab (4), a first and second support (5.1, 5.2) of the slab (4), formed by walls of a width equal to the length of said slab (4) and access means (6) of the water to the interior space (7) of the module (3) arranged at the junction of the slab (4) with the second support (5.2).
    [0083] The height of the first support (5.1) of each module (3) is greater than the height of the second support (5.2). In this way, the slab (4) presents an inclination towards said second support (5.2) that favors the collection of the water that is seeping into the ground and that due to that slope is concentrated in the union of the slab (4) with the second support (5.2), where the access means (6) to the interior space (7) through which the water accesses it are located.
    [0085] In this preferred embodiment of the invention, the two structures (2) that make up the system (1) comprise at least two consecutive modules (3) arranged in the same position, one after the other and joined by waterproofing joints. In this case and as shown in Figures 2 to 4, each structure (2) has 4 consecutive modules (3).
    [0087] Likewise, given that this system (1) has two adjacent structures (2), as can be seen in Figures 3 and 4, the modules (3) of a structure (2) are located in a symmetrical position with respect to those of the structure. (2) adjacent so that the modules (3) of both adjacent structures (2) are arranged with their second support (5.2) adjoiningly and present convergent inclination of the respective slabs (4).
    [0089] Furthermore, in this embodiment, the two adjacent structures (2) are communicated with each other through at least one opening (8) in the second supports (5.2) of at least two adjacent modules (3), as shown in the Figures 3 and 4, since these second supports (5.2) are the ones that are adjacent. These openings (8) allow the passage of the water collected from one module (3) to another adjacent module, so that both structures (2) that make up this system (1) accumulate the same level of water.
    [0091] In this preferred embodiment of the invention, the access means (6) of the water to the interior space (7) of a module (3) are formed by at least one through hole, in this case being in particular a series of holes through lengths along the length of the slab (4). In other embodiments, these access means (6) may be formed by a longitudinal slot of a length less than that of the slab (4) thereof.
    [0093] According to another aspect, in this embodiment, the ends (10) of both structures (2) of this system (1) are closed by means of a concrete wall (12) joined to the respective module (3) by means of waterproofing joints. Likewise and as shown in Figure 3, the stored water outlet means are formed by a connection opening (9) to a conduit communicated with the rainwater network or with a tank, arranged in this case in the first support (5.1) of a module of the perimeter of the system (1). In this case, the stored water is poured directly into said network.
    [0095] In other embodiments, said connection opening (9) can be located in one of the concrete walls (12) closing the ends (10).
    [0097] In other embodiments, it may be interesting that the collected water is directed to an infiltration that feeds the existing aquifers in the area, in which case, the ends (10) of the at least one structure (2) of the system (1) are open and the outlet means for the water stored therein are formed by said open ends (10) and by at least one opening (8) in the supports (5.1, 5.2) of at least one module (3) located on the outer perimeter system (1). In these cases, the system (1) comprises a covering thereof by means of a geotextile.
    [0099] On the other hand, in this embodiment, each module (3) of this system (1) comprises lifting pins (11) for its movement.
    [0101] The described embodiment constitutes only an example of the present invention, therefore, the specific details, terms and phrases used in the present specification are not to be considered as limiting, but are to be understood only as a basis for the claims and as a representative basis that provides an understandable description as well as sufficient information to the person skilled in the art to apply the present invention.
