Abstract

The block is made from steel-reinforced concrete with a trapezoid cross-section to fit in the bottom of a drainage ditch. It is made, for example, with a smaller base 0.50 m wide. its larger one 1.50m, and a thickness of 0.5 m in the middle, with chamfered ends. It can be made in different sizes according to the dimensions of ditches. Four rings are set in the top of the block for handling. When laid in the bottom of a drainage ditch the block tends to hold back water until it is deep enough to flow over it, regulating the rate at which surplus water is discharged.

PRESENTATION DE LA DEMANDE DU BREVET

Figure img00010002

La présente invention, concerne un dispositif, destiné à ralentir et à stopper d'une façon mécanique et hydraulique l'arrivée des eaux de pluie, de ruissellement et de drainage dans les fossés contigus aux voies de circulation routière. PRESENTATION OF THE PATENT APPLICATION
Figure img00010002

The present invention relates to a device, intended to slow down and stop mechanically and hydraulically the arrival of rainwater, runoff and drainage in ditches adjacent to road traffic lanes.

Ces fossés ont pour exutoire, des mares, des bassins de transfert ou de rétention, qui une fois pleins, se déversent dans les rus, talwegs, noues et autres fossés et grossissent rapidement les niveaux des rivières et des fleuves engendrant leurs débordements et créant des inondations sur les berges et les habitations riveraines (figure 2). Le dispositif présenté a fait l'objet d'une expérimentation réalisée manuellement pour argumenter l'efficacité (figures 6,7, 10 et 11) et le bassin aval débordant a baissé de 50 cm, soit environ, 200 m3 après réalisation de l'ouvrage (figures 8 et 9). Le présent dispositif peut être standardisé industriellement par une préfabrication en usine après fabrication de moules à béton normalisés (figures 3, 10 et 11). Le béton devra être armé avec calcul des ferraillages, selon les dimensions de l'ouvrage nécessaire à la retenue d'eau souhaitée et adaptée au site et à la pente du fossé (tableau calcul des volumes d'eau retenue (4)). Le dosage ciment sera aux normes NF de la résistance des bétons selon les essais laboratoires classiques : retrait, résistance, gel. Les côtes du dispositif reprennent les paramètres des godets cureurs de pelleteuse, créant les fossés ou l'adaptant, à hauteurs variables de 30 à 70 cm (cotes godet trapézoïdal de fossé = GB = 1,50 m, PB = 0,50, ht 0, 50, angle du trapèze 450 pour l'exemple). (figures 1 et 3) - Le dispositif est un mini déversoir d'orage, avec débit de fuite sur son plat supérieur (figures 1 et 4), adaptable à la rétention d'eau sur des kilomètres de fossé. These ditches have as an outlet, ponds, transfer or retention basins, which once full, flow into the rus, talwegs, valleys and other ditches and rapidly increase the levels of rivers and streams causing their overflows and creating flooding on the banks and riverside dwellings (Figure 2). The device presented was the subject of an experiment carried out manually to argue the efficiency (Figures 6,7, 10 and 11) and the overflowing downstream basin fell by 50 cm, or approximately, 200 m3 after completion of the book (Figures 8 and 9). The present device can be standardized industrially by prefabrication in the factory after manufacture of standardized concrete molds (Figures 3, 10 and 11). The concrete must be reinforced with calculation of the reinforcements, according to the dimensions of the structure necessary for the desired water retention and adapted to the site and the slope of the ditch (table calculation of the volumes of water retained (4)). The cement dosage will meet NF standards for the resistance of concrete according to conventional laboratory tests: shrinkage, resistance, freezing. The ribs of the device use the parameters of the backhoe digger buckets, creating the ditches or adapting it, at variable heights from 30 to 70 cm (trapezoidal ditch bucket dimensions = GB = 1.50 m, PB = 0.50, ht 0, 50, trapezoid angle 450 for the example). (Figures 1 and 3) - The device is a mini storm overflow, with leakage rate on its upper dish (Figures 1 and 4), adaptable to water retention over kilometers of ditch.

- Sa stabilité dans le fossé est assurée par son poids et peut être, dans les cas de fossés à pentes importantes (supérieures à 4%), renforcée par des fers à béton coulés dans l'ouvrage, en dépassement du fond du fil d'eau, piqués dans la terre du fossé, sur la petite base et les flancs. Figure 5 (1). - Its stability in the ditch is ensured by its weight and can be, in the case of ditches with large slopes (greater than 4%), reinforced by concrete irons poured into the structure, beyond the bottom of the wire. water, stuck in the earth of the ditch, on the small base and the sides. Figure 5 (1).

- Il évite la saturation des mares et des bassins et leurs débordements ou la création de bassins surdimensionnés, nécessitant l'emprise de terres agricoles et leur perte d'exploitation.  - It avoids saturation of ponds and basins and their overflows or the creation of oversized basins, requiring the grip of agricultural land and their loss of exploitation.

- Son action de blocage des eaux entraîne les phénomènes suivants :
Evaporation lente ou rapide selon le climat de la zone considérée.
- Its water blocking action causes the following phenomena:
Slow or rapid evaporation depending on the climate of the area considered.

Infiltration lente ou rapide selon la nature des sols En cas de surcharge ou pentes importantes, adaptation du dispositif en escaliers altimètriques, selon le cycle du calcul hydraulique (paramètres de pente, de hauteur) qui détermine la fréquence de l'invention à adopter (figures 2 et 4). Slow or fast infiltration depending on the nature of the soil In the event of overload or significant slopes, adaptation of the device in altimetric staircases, according to the hydraulic calculation cycle (parameters of slope, height) which determines the frequency of the invention to be adopted (figures 2 and 4).

Le dispositif, usiné et moulé en béton armé doit comporter quatre anneaux de levage (figure 3 (1)) et de manutention aux normes, pour permettre son transport, sa décharge et sa pose en toute sécurité dans le fossé (figures 1 et 2) créé ou curé, par un engin de levage conforme à la réglementation en vigueur. The device, machined and molded in reinforced concrete must include four lifting rings (Figure 3 (1)) and handling standards, to allow its transport, its discharge and its safe installation in the ditch (Figures 1 and 2) created or curated, by a lifting device in accordance with the regulations in force.

Les pentes des rampants, donc sa forme dans toutes les dimensions de hauteurs préfabriquées, doivent être conformes aux normes de sécurité routière et présenter des parois inclinées à 1 pour 3, afin d'assurer la protection de véhicules qui heurteraient cet ouvrage dans les fossés, au même titre que les têtes d'aqueduc de sécurité (figures 1 et 5). The slopes of the crawlers, therefore its shape in all the dimensions of prefabricated heights, must comply with road safety standards and have walls inclined 1 to 3, in order to ensure the protection of vehicles that would strike this structure in ditches, as well as the safety water heads (Figures 1 and 5).

II fonctionne avec un trop plein de sécurité calculé selon la profondeur du fossé (figures 6 et 7 et tableau calcul des volumes) adapté à chaque site, selon la pente, le pouvoir pénétrant du terrain, la périodicité des ouvrages à

implant (Figures 2 and 4).

L'implantation de l'ouvrage entraînant la présence d'eau dans les fossés est recommandée hors zones agglomérées, afin de préserver la quiétude des riverains, par les risques d'infiltration des sols, les moustiques en période estivale, les odeurs d'eau croupissante en terrain imperméable et toutes autres nuisances possibles. The installation of the structure causing the presence of water in the ditches is recommended outside built-up areas, in order to preserve the tranquility of the residents, by the risks of soil infiltration, mosquitoes in summer, water odors rotting in impermeable ground and all other possible nuisances.

Le présent dispositif est destiné à minimiser et enrailler le phénomène de crue des fleuves et rivières, entraîné par la saturation des terres des plateaux amonts. The present device is intended to minimize and stem the flooding phenomenon of rivers and streams, caused by the saturation of the lands of the upstream plateaus.

Il a pour but de bloquer et répartir l'eau de ruissellement dans les fossés existants ou créés (figure 2). Its purpose is to block and distribute runoff water in existing or created ditches (Figure 2).

Il permet de remédier aux paramètres suivants : a) Imperméabilisation des plates-formes des voies de circulation. b) Drainages intensifs des terres agricoles se déversant dans les fossés existants ou à créer. It makes it possible to remedy the following parameters: a) Waterproofing of the platforms of the traffic lanes. b) Intensive drainage of agricultural land discharging into existing or to be created ditches.
