Description

PREFABRICATED SEWER DESCRIPTION Background and field of the invention The present invention relates to prefabricated building elements and more specifically to prefabricated concrete culverts used in the field of construction. At present the sewers used in the field of roads are constructed by straining in the place floor, walls and upper part by means of shoring. This method is relatively slow, expensive and delays the completion of roads. The present invention overcomes these obstacles by introducing a novel sewer system which is or can be prefabricated in the plant or site for later assembly. It basically consists of a couple of modules which are assembled in place and joined by means of suitable elements such as concrete forming culvert elements. The modules are assembled in pairs, to form a first sewer element. This first sewer element is subsequently joined to another sewer element also by means of some suitable element. In the preferred embodiment, the modules are manufactured with reinforced or prestressed concrete and are joined by means of a cement-sand mixture, but it should be understood that the materials to be used for their preparation may vary and include materials such as wood, plastic, or cast metals or fabricated and the joining elements may include binder mixtures such as cement-sand or the simple assembly force between their joining edges.

Brief description of the figures Figure 1 is a front view showing a culvert element formed by two base modules. Figure 2 is a top perspective view of the culvert. Figure 3 shows a detail of the assembly between the base modules.

As shown in Figure 1, the cross section of the base module 1 for the culvert element 2 is rectangular in shape. The lower part of the base modules 1 has a kick 4 in the form of Z in front view. The upper edges 3 (Fig. 2) of this module have sacks 3a in its front part and flanges 3b in its rear part, these saques and flanges are the elements by means of which the sewer elements 2 are to be joined to each other . As seen in Figure 1, the upper internal corners have been modified to form a chamfer which can be of straight or curved configuration in different radii. This characteristic, as is well known to those with average knowledge in the field, imparts characteristics of mechanical resistance. This chamfer can be continuous or interrupted.

As shown in Figure 3, the most preferred mode the base module is constructed of reinforced concrete designed in accordance with the load requirements of the same. In another preferred embodiment, the base module is constructed of prestressed concrete designed in accordance with the load requirements thereof. The shape of the segment 3b in the preferred embodiments is preferably of trapezoidal cross section. An alternate modality for this base module is that which has a segment of circular configuration in transverse view, as it is evident one of the upper edges 3a or 3b will have a concave configuration while the other of the edges should have a convex configuration. It will be evident to those with average knowledge in the matter that the dimensions and proportions between the different parts that constitute the base modules will depend on the dimensional needs and mechanical resistance imposed by the type of work to be carried out, without these variations being beyond the scope of the present invention. The culvert object of the present invention is formed by means of a series of culvert elements 2 formed by base modules 1. Such culvert elements are joined together by means of their segments 3a while the base modules are joined together by means of the serves 4. Thus, the culvert is formed by joining the culvert elements either through a binder such as concrete or a cement-sand mixture or only by the assembly of its components.
