comprising constructing "in situ" a shoe (1) made of reinforced concrete, with part of the frame (2) projecting superiorly therefrom; mount on the shoe an elevation (3) based on prefabricated elements (4), with part of the reinforcement (5) protruding in coincidence with the reinforcement (2) of the shoe; and concreting a block (7) of connection between shoe and elevation, coinciding with the protruding reinforcements of the shoe and prefabricated elements.

Description

Wall manufacturing process containment.

Field of the Invention

The present invention relates to a manufacturing process for retaining walls, consisting of a shoe and an elevation, which can be used as a wall of land containment and for other applications.

Background of the invention

The retaining walls of the type indicated are generally constructed by concreting " in-situ " in its entirety, prior execution of the corresponding formwork and the assembly of the necessary reinforcements.

This traditional construction system requires a high build and set time and also may not allow to achieve the optimum characteristics of resistance.

Description of the invention

The present invention aims at a method of manufacturing retaining walls of the type exposed, consisting of a shoe and an elevation, in which the elevation of said wall is composed of precast concrete elements armed that, as such prefabricated, can be obtained with the desired characteristics.

With the constitution cited, the wall can be achieved in a shorter time of execution and with some characteristics  superior techniques

In accordance with the invention, the wall is composed of a shoe, which is executed " in-situ ", by a prefabricated elevation, and by a block or junction between shoe and elevation, which is also executed " in-situ ", all the aforementioned components being made of reinforced concrete.

The shoe is constructed " in-situ " based on reinforced concrete, with part of the reinforcement protruding superiorly, behind the area that the elevation will occupy.

The elevation, meanwhile, is composed of elements  prefabricated, also based on reinforced concrete, section vertical coinciding with that of said elevation. Part of the armor of these elements protrudes in coincidence with the armor that protrudes from the shoe, with which it intersects.

The reinforcements that protrude from the shoe and elements that make up the elevation are completed with an auxiliary reinforcement, all of them forming an armor for the block or joint between the shoe and elevation, in which they are occluded. This block is obtained by mounting the necessary formwork and corresponding concreting. The assembly of the auxiliary reinforcement, formwork and concreting of the block or zuncho is carried out " in-situ ".

Preferably between the shoe and the elevation is pour a "groutt" or fine mortar without shrinkage, to eliminate the risk of gaps between the elements that make up the elevation and the area of pampering on the shoe.

The described system allows to obtain the elevation by prefabricated elements, which may be available, in perfect setting conditions, at the moment when the shoe is built and able to withstand the mounting of the raised, being necessary to build only the formwork of al shoe and of the block or junction between the shoe and elevation, the which supposes a considerable reduction in the formation of formwork Essentially with the system of the invention they are reduced construction, setting and finishing times.

Brief description of the drawings

The attached drawings show, in a way schematic, the constitution of the wall obtained with the procedure of the invention, being:

Detailed description of one embodiment

According to the invention the wall of containment of the invention is composed of a shoe, an elevation and a block or junction between elevation and footing.

Figure 1 shows in side elevation the shoe 1 of the wall, which is obtained by concreting " in-situ " with the corresponding reinforcement, which will partially protrude from the upper base, as indicated with reference 2, immediately behind of the area that will occupy the elevation of the wall.

As shown in Figure 2, the elevation 3 of the  wall will be composed of 4 prefabricated elements, whose section vertical will correspond to that of said elevation. This elements Prefabricated 4 will also be made of concrete armed, partially protruding its armor 5 from the side in the that the armor 2 of the shoe 1 protrude, intersecting each other the reinforcements 5 of the prefabricated elements 4 and the armor 2 of the shoe 1.

The assembly of the prefabricated elements 4 can be carried out, as shown in Figure 3, by auxiliary fasteners 6. The set of reinforcements 2 and 5 protruding from the shoe and the prefabricated elements 4 can be completed by means of an auxiliary reinforcement for proceed subsequently, by placing the corresponding formwork, to the concrete " in-situ " of a block or joint 7 between shoe 1 and elevation 3, all as shown in Figure 4, leaving the block or joint 7 from the outer side to the retaining wall.

As seen in Figure 3, between the base upper of the shoe 1 and the lower support base of the prefabricated elements 4 a "groutt" or mortar can be poured fine without retraction, indicated by reference 8, for eliminate the existence of possible gaps in the contact area between shoe 1 and prefabricated elements 4.

In this way, retaining walls are obtained by using prefabricated elevations perfectly embedded in the shoe, obtained " in-situ ".

The reinforcement of the joint block between elevation 3 and foot 1 could be constituted only by the armor 2 and 5, protruding shoe and prefabricated elements.
