FR2860571A1 - Underground drainage duct for rain or surface water is made from side walls of recycled tires stacked side by side - Google Patents

Abstract

The duct, designed to be laid in a trench, is made from assembled rings (2) of used tire side walls (1B, 1C) that are stacked together side by side inside the tread (1A) of a tire (1) with one side wall removed. The tires are all of the same type, are cut to the same size and have side walls facing the same way. The duct, designed to be laid in a trench, is made from assembled rings (2) of used tire side walls (1B, 1C) that are stacked together side by side inside the tread (1A) of a tire (1) with one side wall removed. The tires are all of the same type, are cut to the same size and have side walls facing the same way. The number of assembled side walls in each section is designed to give reinforced resistance to diametrical pressure, and holes can be cut in the tops of the tire sections for water to enter the resulting duct, the ends of which can be consolidated with concrete to receive protective grids.

RECYCLED TIRES

DESCRIPTION

  FIELD OF THE INVENTION The invention relates to the field of high-flow buried pipes for channeling ditches and draining rainwater or runoff from land situated upstream and obtained by the juxtaposition of recycled tires.

BACKGROUND TECHNOLOGY

  There are known methods for producing pipes, more particularly for irrigation, by means of specific extruders starting from a material formed partly of crushed rubber coming from the recycling of old tires: unfortunately, the pipes obtained by this technique, can not be used, due to their low crush resistance, as a buried drainage pipe.

  Rigid, commercially available drainage pipes are also known for use as a drainage pipe: unfortunately, their limited diameter and high cost (plurality of drainage notches) is a brake on their development.

  Drainage pipes of various types of water are also known comprising a plurality of juxtaposed tires arranged in trenches and covered with earth: unfortunately, in order to obtain acceptable crush resistance, it is necessary to use very large tires (heavy goods vehicles). for example) with

for disadvantage the realization of large trenches of a consequent cost. SUMMARY OF THE INVENTION The purpose of the invention is to provide a high flow line obtained by the juxtaposition of recycling tires, more particularly of passenger vehicles, by reinforcing their resistance to crushing, by creating a continuous central flow duct. water and promoting, on the one hand, self-centering and self-maintaining the tires between them and, on the other hand, the drainage of water between two contiguous tires. This pipe is usually consolidated at its ends by concrete to receive protection grids. The pipeline, according to the invention, which comprises a plurality of tires, juxtaposed, 30 is essentially characterized in that: - each tire contains a juxtaposition of cut-off flanks, in the form of washers, according to very specific cutting lines, in similar tires; The number and dimensions of said cut flanks are adapted to reinforce the diametral crushing resistance of the tire and to create a continuous central flow conduit. According to particular features of the invention: - each tire containing the juxtaposition of cut flanks has only one flank associated with the tread, the other flank having been cut, in order to facilitate the introduction of flanks intended to be juxtaposed; - The cut flanks are positioned against the remaining side of the support tire, profiles in the same direction; the last cut edge, lateral side of the support tire, protrudes from said tire so as to fit into the next tire in order to ensure self-centering and self-holding of said tires together; - The edge of the cut edge of the support tire promotes the lateral drainage of the water. The interest also lies in being able to close a ditch while the parcel that one wishes to enlarge by the closure of this ditch already receives rainwater or runoff coming from the lands situated upstream. In this case, this pipe may serve as a drainage conduit for the plot where it will be laid. It is therefore imperative to include a protective grid at the entrance in the upper part to prevent the entry of large trash (eg branches) or animals. At the exit, a pivoting grid must also be integrated to avoid the entry of animals. This can be raised by pivoting to evacuate clumps of leaves (system already existing commercially or can be manufactured on demand). PRESENTATION OF THE FIGURES The characteristics and advantages of the invention will appear more clearly on reading the detailed description which follows of at least one preferred embodiment thereof given by way of non-limiting example and shown in the drawings. attached. In these drawings: - Figure 1 is a diametrical sectional view of a standard tire; - Figure 2 is a diametrical sectional view of a tire according to the invention; FIG. 3 is a detailed view showing the direction of the tire with respect to the flow of water; - Figure 4 is an overall view in elevation of the juxtaposition of tires; FIG. 5 is an internal detail view, according to the arrow (F), of the cut made on the juxtaposed central flanks of a given tire for the collection of water coming from a secondary drain; - Figure 6 is a side view of the tire of Figure 5 highlighting the location of the corresponding cut and that made on the support tire; - Figure 7 is a side view of a pipe positioned in its trench. DETAILED DESCRIPTION OF THE INVENTION The pipe shown in the figures comprises a plurality of tires (1), 10 juxtaposed, generally consisting of a tread (1A) and at least one sidewall (1B, 1C). Each tire (1) contains a juxtaposition of flanks (1B, 1C) cut in the form of washers (2), along cutting lines (D1) and (D2), in similar and adapted tires, in their number and their dimensions, to enhance the diametral crushing resistance of the tire and to create a continuous central duct (C) for the flow of water. For example, for a support tire (1) of dimensions 145x70x13, the filling flanks (2) will be cut in tires of greater diameter but always in 13 inches. The number of flanks (2) is generally between 10 and 15. Each tire (1), containing the juxtaposition of cut flanks (2), has only one flank, for example (1C), associated with the tire strip. bearing (1A), the other sidewall (1B) having been removed after cutting along the cutting line (D1). The cut flanks (2) are positioned against the side (1C) of the support tire (1), profiles in the same direction. Each tire (1) is arranged in such a way that the inclined inner ends (P) of the sidewall (1C) of the carrier tire (1) and the cut flanks (2) are positioned in the direction (E) of the water flow so as to to avoid retentions, such as leaves, which are at the origin of flow decreases, or even obstruction of the pipes. A portion of the tread (1A), cut along the cutting lines (D1) and (D2), covers the upper part of the junction between the tires (1) juxtaposed, taken in pairs. The length of said tread is adapted to block the backfill earth in the upper space (G) existing between two consecutive tires. It is generally constituted by running half strips 2860571 4 recovered on the tires used to recover the filling flanks. At least one intermediate tire (1 N) may comprise a cut-off portion (R), serving to receive a secondary drain (3) of the type ringed drain existing commercially, the position of which must not exceed the horizontal portion of the diameter, but may be placed at any higher level, left or right side of the pipe. Over the length of the pipe, it will be possible to have as many secondary drains of small section as necessary. The opening (R) may consist of a cutout (1E) made on the tire (1 N) and cuts (H, L) made on central juxtaposed sidewalls (2A). The juxtaposed tires (1) are positioned in truncated trenches (4) whose dimensions are adapted to keep them aligned and wedged. The ends of the pipe are consolidated by concrete adapted to receive protective grids. Of course, the invention is not limited to the embodiments described and shown for which other variants may be provided, in particular in: - the dimensions of the tires used; the number of filling flanks; the type of cut made in the tire and in the filling elements, or even the use of an independent intermediate sleeve comprising a flange for maintaining the secondary drain; and extend it to all water drainage applications, regardless of the nature of the terrain.
