Description

MOBILE CONCRETE PRODUCTION PLANT Object of the invention

[0001] The present invention relates to a mobile concrete production and distribution plant comprising means for producing concrete, as well as means for recycling runoff water and / or wash water from the mobile plant and / or washing water from the means of handling and / or transporting concrete and to a method for implementing such a concrete production and distribution plant. State of the art

[0002] In the field of construction, whether in the building sector or in the public works sector, the construction elements used, such as pillars, walls or slabs, are generally made of concrete, or include concrete, a well-known material, which is an assembly of water, aggregates, such as gravel, pebbles or sand, with a binder, such as cement, bitumen or clay, and often also admixtures, modifying the physical and chemical properties of the final mixture.

[0003] Although these building elements can be prefabricated in a factory, and therefore ready for use, and then transported to the site, they are more generally made on site, which requires transporting the concrete from a fixed concrete production plant, which may be located a great distance from the site(s), resulting in significant transport costs and negatively impacting the progress of the construction sites.

[0004] Mobile concrete production plants were then proposed, which are transported and assembled near a construction site, then dismantled at the end of said construction site, to be transported and reassembled near another construction site.

[0005] For example, document EP0468827 describes a mobile mixing station, mounted on a transport chassis, which can be used in association with a mobile aggregate storage unit, and at least one mobile cement silo, as well as means for storing and distributing water and means for storing and distributing admixtures.

[0006] Some of the mobile plants are equipped with means of recycling the surplus concrete produced.

[0007] For example, document WO2021183174 describes a mobile and modular concrete production plant comprising a plurality of individual units mounted on skids, each including various complementary means necessary for concrete production, and which are functionally connected to each other. The concrete plant does not include settling basins, but includes means for recycling unused fresh concrete, provided at the plant's water supply unit. These wet concrete recycling means include an aggregate screen and a sand screen, positioned above a retention tank, which is part of the main water reservoir, and a pump for transferring the recycled water from the retention tank to the main reservoir of the water supply unit.

[0008] The concrete manufacturing process requires regular cleaning of the production equipment used, in order to guarantee its long-term lifespan, but also to allow the production of different types of concrete, by reducing or eliminating contamination from one batch to another.

[0009] For example, document CN103601259 describes a concrete production plant including means for recycling the wash water from the plant's mixer. These means include a wash water guidance device located under the mixer, which directs the wash water to a treatment unit comprising a removable tank equipped with a filter and a pump. The treated water is discharged to a wastewater dosing unit located at the top of the plant and connected to the mixer for reuse in concrete production.

[0010] Furthermore, concrete handling and transport equipment, including pump vehicles or transport vehicles bringing concrete to construction sites, also need to be cleaned periodically to ensure their proper functioning in the long term and to reduce the risks of contamination between the different types of concrete produced by a concrete plant.

[0011] Concrete production plants do not offer solutions for the recovery and recycling of runoff water and / or washing fumes from such concrete handling and / or transport equipment, the cleaning of which materials are generally washed in dedicated washing stations, separate from concrete production plants.

[0012] However, for concrete mixers, document FR2192489 describes a washing station for their mixing tanks. The station comprises a structure incorporating a concrete sludge reception and dilution tank, a sludge pump to lift the sludge to a storage and settling hopper located above the reception tank, and connected to a series of cascading settling tanks allowing for a second settling of the water before it passes through a filter and is then stored in a storage tank located above the storage and settling hopper. The recycled water is then reused for diluting the concrete sludge in the reception tank or for washing the concrete mixer tanks.

[0013] Besides being expensive in terms of the amount of water consumed, such dedicated washing stations have the disadvantage of being bulky, having a large footprint, and therefore being installed far from construction sites, which has the additional disadvantage of being time-consuming and uneconomical, as the concrete transport vehicles are unavailable while they are being washed, which negatively impacts the progress of the construction sites. Objectives of the invention

[0014] The present invention aims to provide a mobile concrete production and distribution plant, and a method for implementing such a plant, which do not have the drawbacks of the prior art.

[0015] The present invention aims to provide an alternative to existing prior art solutions.

[0016] The present invention aims to provide a mobile concrete production and distribution plant, which is easily transportable, autonomous in its operation, which is equipped with the concrete production means of fixed production plants, while offering a solution for the recovery and recycling of runoff water and / or washing fumes from all or part of the concrete production means and the concrete handling and / or transport equipment, in particular pump vehicles or transport vehicles bringing concrete to construction sites.

[0062] In a preferred embodiment of the invention, shown in Figures 1 to 3, the recycling means 11 comprise four rectangular parallelepiped-shaped bins 14. However, depending on the size of the mobile unit 1 according to the invention, the recycling means 11 may comprise more than four bins 14, preferably as many as necessary, advantageously of a shape and dimensions compatible with or adapted to the mobile unit 1.

This facilitates and accelerates settling and makes it easier to recover solid particles. Preferably, the inclined ramp 17 is fitted to the tank(s) 14 intended to receive the water to be recycled containing the most solid particles to be settled. This could be, for example, the tank(s) 14 arranged perpendicular to the tank(s) 14 forming the foundations 10.
