Description

Modular tank for drainage or stormwater storage.

Object of the invention

The system falls within the sector of urban drainage, specifically part of what is known as Urban Sustainable Drainage Systems (SUDs or BMPs). The SUDS will they can define how to use a series of techniques, structures and permeable materials, preferably vegetated, that favor water infiltration into the ground and contribute to not alter the hydrology prior to the urbanization process.

These systems are booming thanks to the emergence of new regulations such as the Water Framework Directive (DMA), which attempts to mitigate and limit the serious effects that increasing soil waterproofing, product of the activity urban development, causes the soil, the atmosphere and the natural cycle of water, such as soil desertification, increased ambient temperature and the fracture of the natural water cycle, generating an increase in surface runoff and with it the Pollution and floods.

Given their versatility and flexibility these Modular deposits can be used for infiltration or for stormwater retention in many applications, such as vegetated roofs, gardens, parking lots or roads. They can be sized to size, connecting each other, and withstand the loads of terrain and rolling traffic.

The procedure to install the tanks modular consists of placing them buried, wrapped with a geotextile blanket as a filter, which also constitutes a means of protection that prevents the invasion of the deposit by the roots of surrounding plants. Optionally wrapped in another sheet waterproof if water is intended to accumulate in the system. Later everything is covered with a layer of sand that allows filter the water that will penetrate from the outside and is capable of cushion loads on the surface.

The system allows the water to infiltrate the land, decreasing urban runoff and water volumes poured into a channel, or retain water and thus reuse it to other uses, such as irrigation, industrial processes or cleaning of streets The excess water in both cases can be led to ponds or wetlands, revaluing the landscape aspect and playful environment, or can be poured directly and in better condition to the receiving medium.

Background of the invention

The state of the art of drainage technology existing, similar to the proposed design, reflects the clear need to improve current systems by others with features improved, according to current drainage needs in the construction and manufacturing and distribution costs more competitive.

Currently you can find two types of drainage tanks: systems with a structure in three dimensions that do not require assembly on site; and the systems modular that require a pre-assembly of the work.

The first although they save labor in the preinstalled, they need a lot of gross space in their transport what which in turn implies a very large extra cost that penalizes the final price of the product put into work.

This inconvenience does not occur in the case of dismantled modular systems, since transportation costs are reduce considerably and manufacturing many times too for being a assembly of smaller pieces. For him On the contrary, they require an extra pre-assembly work on site than in In general, it does not imply a great cost overrun Simple and manual by one or two people.

There are other deposit systems of intermediate technology of different types, such as modules that have intermediate columns inside to give it rigidity. These structures are formed by a single piece, with a complex framework, which will need a large capacity machine to inject it, which means more manufacturing cost high.

There are also honeycomb structures of bee composed of vertical plastic columns shaped hexagonal joined together, and modules manufactured by welding or gluing profiled sheets. These structures are resistant in direction vertical, but flexible in the horizontal, so they demand to have special care in its placement and in the forecast of loads horizontal they could bear.

Description of the invention

The proposed tank is of the modular type disassembled, consisting of two types of plates (lateral exteriors and intermediate) joined together forming a prism, which has the advantage of being more flexible than the others, being able to add more intermediate plates to increase their resistance as required by the application for which they are intended and can be stacked using the lower tank as a base, thus saving parts. Besides, his manufacturing cost is lower when doing it for parts, which are flat plates, easier to inject than an entire module. So it also lowers the cost of transport to stack these pieces, being able to transport more deposits with the same gross space

The deposit of the invention, with the rest of the deposits of the same type, have better characteristics than their competition in terms of mechanical resistance. It also has a higher accumulation capacity so a smaller number will be necessary of modules to cover the same volume and, together with presenting a lower percentage of material, by volume of cubic meter stored, it is cheaper than the existing models in the market.

According to an important feature this tank allows to install 1, 2, 4, or 5 intermediate partitions without vary the design of your pieces, so you have more flexibility than other existing deposits in the market.

It also has the great advantage of incorporating guide rings in the intermediate pieces, which facilitate the task of connection of conventional drainage pipes without compromising their mechanical strength. These holes are designed for several sizes corresponding to the standard diameters of the drain pipes Also these holes can serve to perform cleaning or monitoring of deposits, in addition to Increase your storage capacity.

This type of modular deposits allows to create large deposit networks easily; manufacturing process very simple, which entails a lower cost; transport disassembled, with which reduces this cost by being able to transport more quantity of pieces by volume; ease of assembly on site; ease of connection of drainage pipes.

Preferred Embodiment of the Invention

As can be seen in the figures referenced the modular tank (3), described herein memory, consists of two types of plates (1) and (2), represented in figure 2, which are connected to each other by tongue and groove to form a cubic structure. For assembly the pieces must be arranged as indicated in figure 4, using a rubber hammer to once dock coupled between yes.

For this purpose the piece (2) has some projections or males (21), which are introduced into the holes (11) of the piece (1) under pressure, thus joining both pieces in the direction orthogonal to form from a type (1) piece that constitutes the base of the tank the edges of the same using pieces type (2) and finally close the sides and the upper base with new Type parts (1).

It is possible to place intermediate partitions in your interior, which are formed by pieces (2). This is how it is achieved increase the resistance of the tank, if the specific application for the one that is going to be installed so demands it. Figure 4 shows the tank with 3 intermediate partitions; however this number does not It is binding to the invention and can vary from 0 to several panels intermediate

In figure 5 you can see the assembly procedure of a set of two stacked tanks (3a-3b). In the same way you can mount tanks annexes and more complex structures of coupled deposits forming a multiple deposit of the basic module represented in figure 1. With this simple way you can generate large spaces of Drainage with resistant structure saving material costs and labor force compared to other alternative systems such as Concrete or gravel drain deposits.

On the other hand, the proposed deposit has two hoops (22-23) of material in the meshing of their partitions, easily cut-out, preferably including the smallest within the elder When breaking one of these rings a hole is formed that allows to connect in it tubes of entrance or exit, for the connection to other drainage networks or to evacuate water to the environment receiver or reuse it for irrigation or other uses. Holes generated (41-42) have the diameter of pipes normalized by what endow it with a very interesting quality, the which does not compromise its resistance, as has been proven. further These holes can be used for cleaning or module inspection, in addition to providing it with greater capacity Hydraulic or accumulation. Figure 6 shows both deposits with the hole made in different sizes provided.

Modular deposits have a plurality of alveolar perforations (31) through which the water that is retained inside when installed underground buried, wrapped with a geotextile blanket as a filter and means of protection against invasion by plant roots surrounding, along with the rest of the elements that form the drainage system, for the infiltration of water in the ground, or its retention for later use. In figure 7 it shows an example of the execution of an urban drainage system full sustainable.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
