Description

DESCRIPTION

DRAINING REINFORCED CONCRETE PAVEMENT EXECUTED ON SITE OBJECT OF THE INVENTION

The object of the present invention, as its title establishes, is a reinforced concrete drainage pavement. The invention contemplates the components of the pavement itself.

What characterizes this development is the special configuration and overall arrangement of a series of elements, as well as specific execution steps using light, modular and biodegradable molds, to achieve the goal of obtaining a draining reinforced concrete pavement executed in situ, which combines the main characteristics of being draining, or permeable to the circulation of water, along with the advantages of reinforced concrete: competitive price, high resistance capacity, uniform surface and little need for maintenance throughout its useful life.

Therefore, the present invention is limited within the field of construction, and particularly the construction of pavements, and more precisely within draining pavements.

BACKGROUND OF THE INVENTION

In pavements, the main function of drainage systems is to evacuate any accumulations of water that occur on them after rain events. It is essential that this evacuation be carried out quickly and efficiently, since excess rainwater on the pavements can cause discomfort, on the one hand, damage to the infrastructure itself and decreased adhesion between the vehicle covers and the road. pavement, significantly increasing the risk of accidents and the risk of flooding. It can be established therefore that the elimination of water is an aspect of great importance in the success or failure of the operation of a road infrastructure, whatever the traffic it receives.

Traditionally, to avoid the problem described, expensive surface drainage systems have been designed along with the infrastructure, capable of collecting the diffuse flow of water on the pavement surfaces and directing it to strategic points in different locations of the infrastructure.

This situation, together with uncontrolled urban growth and the generation of large impermeable surfaces, very significantly alters the natural cycles of water, going from flows distributed in a balanced way to specific and sporadic flows that in no way resemble natural regimes. These situations also cause rainwater to lose quality as it progresses on its way through conventional drainage and sanitation infrastructures, mixing with other types of flows and often ending up in treatment plants, increasing its flow and preventing them from functioning. in its optimal regime.

In this context, the so-called SUDS or Sustainable Urban Drainage Systems arise, which are systems for direct reception of rainwater or surface runoff in which surface infiltration is allowed. These systems, by themselves, can close the water cycle since they connect the surface of the pavements with the permeable substrate.

There are many permeable pavement systems that have been generated over the years. Normally permeable pavements are of two types depending on the way in which water passes through it: pavement formed by a porous material that allows water to pass through it, which presents many problems of filling gaps and maintenance, and pavements formed by non-permeable elements arranged with an open joint through which water is introduced, which present problems of rolling discomfort and durability if the traffic that circulates over them is of a certain magnitude.

The reinforced concrete drainage pavement presented aims to achieve the advantages of the typologies described above, combining with its drainage capacity the advantages of reinforced concrete slabs: competitive price, uniform surface, high resistant capacity and little need for maintenance throughout its useful life.

DESCRIPTION OF THE INVENTION

To solve all the problems previously identified, the following solution is presented, which will be essentially included in the first claim of this utility model.

The object of the invention is a reinforced concrete drainage pavement fundamentally comprising:

• A traditional reinforced concrete slab that has cross-shaped surface grooves, through which water can flow and which provide this slab with drainage capacity.

• An arrangement according to a regular plan pattern of the surface slots, which allows the reinforcement of steel bars necessary to form the reinforced concrete to be placed between them.

• Cavities under the cracks located on the upper surface of the pavement that connect it with the base of the pavement, and through which water can circulate.

• The anterior cavities under the slits located on the upper face that have a geometric shape resulting from the intersection of two triangular prisms, so that they can optimally resist the pressures of the concrete before it sets, when it is in liquid form.

The reinforced concrete drainage pavement described here is a reinforced concrete element, so it is designed to resist the loads imposed by the Spanish technical regulations for traffic corresponding to pedestrian or light traffic uses.

The reinforced concrete drainage pavement described here is characterized in that the fresh concrete is poured onto biodegradable and lightweight lost molds or formwork, based on cardboard or papier-mâché, constituting the negative shape of the resulting reinforced concrete pavement. Once the molds have been placed on the ground and after placing the steel reinforcement with electrowelded mesh, the fresh concrete is poured to the top of the lost molds or formwork. When the concrete has already set and reached a minimum resistance, the characteristic grooves of the upper surface are generated by reducing the thickness of the pavement from its upper face, through a mechanical milling operation of the pavement or by mechanical bush hammering of the same.

All the characteristics described in the previous paragraphs make up a pavement that presents the resistant and low-maintenance advantages of reinforced concrete, together with its drainage capacity. What stands out above all is its low-maintenance features, compared to draining concretes with large gaps that fill up in a very short period of time, an aspect that makes them unsuitable for the function for which they were designed.

In a possible embodiment, the overall thickness of the reinforced concrete drainage pavement can range between 10 cm and 30 cm.

In Figure 2 you can see a portion of the concrete drainage pavement that has been cut along the axis of the grooves. In Figure 2 it can be seen that under the surface cracks of the pavement there is a cavity (3) through which water can circulate, which preferably has a growing section from the upper face towards the lower. In a possible embodiment, this cavity may have a geometric shape resulting from the intersection of two triangular prisms of the same height placed transversely to each other and with the same orientation, so that the cavities have a growing section from the face. top of the pavement and towards the underside. In a possible embodiment, the base of the triangular prisms can be square, with a length of 75 mm, and their height can be 150 mm.

Figure 3 shows the initial level up to which the lost mold or formwork (4) is concreted, which subsequently, in a possible embodiment, is superficially lowered to the final level (5) through a milling technique. of pavement or mechanical bush hammering, until obtaining the superficial drainage grooves (1) that characterize it.
