Definitions

  • Such machines are often used for soil stabilization and / or mortaring, i.e. used to increase the load-bearing capacity of poorly loadable floors or to create a hydraulically bound base layer.
  • the process is based on mixing the soil with hydraulic binders (lime, cement (suspension), emulsion, etc.), which binds the moisture. Then the surface can be leveled using a grader and compacted using a roller.
  • the milling of the soil and simultaneous mixing with the binder is usually carried out with a so-called soil stabilizer, which has a milling / mixing rotor for this.
  • the binder is applied to the ground beforehand using a separate spreading vehicle.
  • the spreading vehicles are usually built on the basis of a three-axle truck and are therefore not very suitable for off-road use.
  • the time between the spreading and the milling in is relatively long, which favors a possible blowing away of the binder and a strong dust development.
  • Cement can also be added as a suspension (dissolved in water) for dust-free addition.
  • this method can only be used if additional water is to be introduced into the soil. This method is not suitable for soils that already have too high a water content.
  • the suspension mixer must be pushed or pulled in front of or behind the machine, which in turn is only possible in relatively flat terrain.
  • the invention has for its object to develop a machine of the type mentioned in such a way that the - 3 -
  • Binder can be introduced without adding water and reducing dust formation.
  • the invention advantageously provides that a storage container and a metering and discharge device for powdered binders connected to the storage container are arranged directly in front of the work roll in the working direction.
  • the invention accordingly provides for a complete metering and discharge device for powdered binder with a corresponding storage container to be integrated into a known machine for soil stabilization. This ensures that the binding agent can also be applied wherever a soil stabilizer can work.
  • the storage container and discharge device are arranged directly in front of the milling drum. This means that the binder remains on the surface of the floor for a few seconds before it is milled.
  • the dosing and dispensing unit is sealed except ⁇ to the hood of the milling out with flexible walls.
  • the dosage is regulated purely volumetric or additionally taking into account the mass actually carried out.
  • the purely volumetric dosing controls the speed of the rotary valve as a function of the current driving speed.
  • One revolution of the rotary valve corresponds to a precisely defined, unchangeable volume flow in 1 / revolution.
  • the storage container for the binder can be hung on load cells. The speed is then regulated based on the mass of binder actually discharged in kg.
  • the storage container is filled pneumatically, i.e. the binder is blown into the container.
  • the forcibly generated exhaust air is cleaned in an exhaust air filter before it is released into the environment.
  • filling level sensors continuously check the filling quantity. If the fill level falls below a certain level, the vibrating vibrators in the storage container are switched on, which loosen the powdery binding agent still stuck to the walls and cause them to slide off. If the level falls below the lowest level, a warning signal is activated.
  • Fig. 1 is a schematic side view of the machine according to the prior art.
  • FIG. 2 is a schematic side view of the appropriate machine.
  • FIG. 1 shows the machine for processing lanes according to WO 96/24725 with a machine frame 1 carried by two running gears and a driving station consisting of a driver's cabin 23.
  • the driver's cabin 23 can be displaced transversely to the direction of travel on the machine frame.
  • the bogies have at the front and rear ends of the machine frame 1 two jointly or optionally individually steerable bogie axles 4, in which each wheel is provided with its own hydraulic drive in the form of a hydraulic motor and can optionally be controlled separately.
  • Each wheel is provided with a height adjustment device 25, so that the height of the machine frame and possibly its inclination can be adjusted exactly to the working or transport height.
  • the entire machine weight is thus concentrated on the area between the chassis axles 4, a hood 7 being fixed in place beneath the driver's cab to the center of the machine and delimiting a working area of a rotating work roller 8 serving as a mixing area.
  • FIG. 2 shows the machine for processing lanes with an integrated storage container 14 for the binder 5, and with a metering and discharge device which is designed in the form of a cellular wheel sluice 10.
  • the storage container 14 extends between the driver's cabin 23 and the hood 7 of the work roll 8 and is fastened to the machine frame 1.
  • the binder 5 can be filled pneumatically into the storage container 14.
  • the storage container 14 is provided with an exhaust air filter 26 so that no binder dust can escape to the outside when the storage container 14 is pneumatically filled.
  • the walls 20 of the storage container 14 can run in a funnel shape.
  • At the lower end of the storage container 14 there is the cellular wheel sluice 10 in a funnel 15, with which the binder 5 can be dispensed in doses.
  • the binder 5 is discharged as a function of the speed of advance of the machine with the aid of a computer control.
  • the rotary valve 10 is connected to a hydraulic motor 12 via a gear 16.
  • flexible sealing walls 18, for example made of rubber mats are provided, which seals the funnel 15, which extends over the entire width of the machine, from the floor 2.
  • the sealing walls 18 are open towards the hood 7, so that the binder 5 dispensed from the funnel 15 is deposited on the floor 2 within the sealing walls 18.
  • the binder 5 is then immediately run over by the work roll 8 and mixed with the milled bottom 2. In this way, no cement or lime dust can escape to the outside, as a result of which the binder 5 can be bound in powder form, ie without water.
  • Level sensors 24 on the walls 20 of the storage container 14 give signals to the controller, wherein these signals can also be used to control vibration vibrators 22, which are also arranged on the walls 20 of the storage container 14.
  • the control of the cellular wheel sluice 10 can, in addition to the control as a function of the speed of advance, also experience a fine control such that a weighing device (not shown in detail) detects the amount of binder discharged and corrects the speed of the cellular wheel sluice 10 accordingly.
  • the weighing device can be, for example, from below the storage holder 14 arranged load cells exist.
  • (5) consists of a rotary valve (10), the speed of which can be controlled depending on the speed of advance.
  • Machine according to claim 2 characterized in that a weighing device, e.g. weighing cells arranged below the storage container (14), the discharged binder mass measures and the speed of the rotary valve (10) additionally depending on the actual

Abstract

L'invention concerne un engin pour travailler des chaussées, notamment pour stabiliser des sols peu résistants à l'écrasement. Cet engin comprend une cabine de conduite (23) pour le conducteur, un châssis automoteur comportant au moins deux essieux (4) munis de roues, un rouleau de travail (8) monté entre les deux essieux (4) et réglable en hauteur par rapport à la surface de sol à travailler, ainsi qu'un moteur d'entraînement (9) pour actionner le rouleau de travail (8), le système de transmission et assurer la puissance motrice requise pour d'autres fonctions. Il est prévu de placer dans le sens opératoire (3) immédiatement devant le rouleau de travail (8), un réservoir (14), ainsi qu'un dispositif de dosage et de décharge (10) relié au réservoir (14), pour un liant (5) sous forme pulvérulente.
