    In apparatus for injecting and mixing a ground stabilization agent into the material of the earth during the operation of an earth drill, a device is provided for generating signals indicative of the upward movement of the earth drill as the drill is withdrawn and while the stabilization agent is being introduced, and a weighing device is provided for constantly weighing the remaining supply of ground stabilization agent and for thereby measuring the weight of stabilization agent delivered to the ground, and a recorder is connected to receive signals from both of the devices for providing a graphic record of the stabilization agent delivered versus the upward travel of the earth drill.

    4 it The invention relates to a construction technique, in particular to devices for introducing a tackle material into the soil, preferably for piling. A device for strengthening the soil is known, which includes a base means, a drill mounted on it with a nozzle for introducing into the soil a powdery tangible material, a bunker, a compressor and a pipeline for supplying the material to the nozzle using compressed air Sch. The disadvantage of this device is that there is no possibility of determining the amount of embedded material introduced into the soil, which leads to uneven proc. soil depth. The closest to the invention is a device for the formation of piles in the ground, including a vehicle, a drill injector placed on it, a chain drive of a drill injector with rotatable elements and an electric switch, a hopper with a support, a pumping equipment, a recorder with a pulse converter. signals and the causative agent of flow rate signals in a live material 2. However, the possibility of using only liquid creeping materials and the use of contact locking devices excludes the possibility of strengthening the soil with powdered materials with the required quality and uniform depth strength, while reducing the reliability of operation due to the rapid wear of the contactors. The purpose of the invention is to increase the reliability of the work and the quality of strengthening the soil when using a powdered cement. This goal is achieved by the fact that in a device comprising a vehicle, a drill-injector located on it, a chain drive of a drill-injector with gear wheels and electrical contactors, a bunker with a support, a pumping equipment, a recorder with a pulse signal converter and a causative agent {consumption material, the vehicle is equipped with directions, the bunker is made with the possibility of vertical movement in the guides, the agent of flow rate signals in the matter is made in the form of a di measuring sensors installed under the bunker support, and electrical switches in the form of ferromagnetic elements evenly located on one of the gears and an inductive sensor interacting with them. FIG. 1 shows the proposed device in the working position, general view; in fig. 2 is a view A in FIG. in fig. 3, view B in FIG. one; in fig. 4 is a block diagram of equipment for driving pulses for their conversion and recording; in fig. 5 is an example of recording a recorder. The device is mounted on the vehicle, the means 1 lattice mast 2, the supporting structure 3 and the hydraulic actuator 4 with tilting levers. By means of the hydraulic drive 4, the lattice mast 2 can be folded back onto the stop 5 when the device is transported. The lattice mast 2 is a guide for a drill-injector 6, hitting a hollow rod 7 connected by a hose to a hopper 8, which is mounted on trailer 10 through bearing 9 on the trailer 10. For vertical movement of the rod 7, there is a chain drive 11 with gear wheels 12 and. engine 13. On the periphery of one of the wheels 12 are evenly arranged ferromagnetic elements 14, for example metal. An inductive sensor 15 is placed against the circumference passing the center of the elements 14, which is associated with a clamping / starting contact 16 of a stepper motor (not shown) of a tape drive mechanism of a recorder 17 located in the cab of the vehicle G./. Under the support 9 of the bunker 8, mounted dynamic sensors 18, for example, four strain gauges connected to the amplifier 19 with the device 20, to balance the weight of the bunker 8 and the flow rate of the tidal material through its dispensing device 21. At the output of the amplifier 19 there is a control device 22 showing the powder in baking material such as lime. The device 22 is connected to the recorder inlet 17. For the operation of the load cell sensors 18, the hopper 8 is mounted with the possibility of vertical movement by means of guides 23,. fixed to the frame of the design 24, which encloses the bunker 8, and to reduce friction, the bunker 8 contacts the guides 23 by means of rollers 25. The device operates as follows. At the site of soil consolidation, the burr detector from the transport position is transferred to the working position by installing the lattice mast 2, by means of a hydraulic actuator 4 to the vertical position. A bor-injector B is rotated, which with the help of a chain drive 11 gradually lowers and loosens the soil to the required depth, while the pressure contact 16 under the action of the rod 7.
    breaks the electrical circuit between the inductive sensor 15 and the recorder 17.
    Upon reaching a predetermined depth, make; lifting the injector b with simultaneous activation of the tips from the bunker 8 through the dispensing device 21 of lime in powder form and the recorder 11 And closing the circuit between the inductive sensor 15 and the recorder 17.
    During lifting of the anorector 6 by means of the drive 11, the gear wheel 12 rotates with ferromagnetic elements 14 fixed on it, each of which passes through the inductive sensor 15 contactlessly excites in it the flow motor / which includes the step motor of the recorder 17, n turning off the tape recording the flow rate of a live material using a signal from a torque sensor 18. As a result, a plot of the flow of a live material by weight and the distance traveled by the drill inlet are plotted on the tape of the recorder 17 b torus during its lifting.
    An example of a recording by the recorder 17 is shown in. 5, which is depicted as a stepped curve 267 along the abscissa axis, which reflects the distance traveled by the drilling injector 6, and along the ordinal axis, the amount of the penetrating material introduced into the soil, in particular lime. The horizontal portions of curve 26 show that during this period no feed was delivered to the holding material in the soil, but the bur-injector continued to move upwards.
    Curve 26 makes it possible to determine (The amount of lime introduced into the soil at the Depth, expressed, for example, in kilograms per linear meter.
    The proposed implementation of the device with the recording of the flow rate in the holding material over the depth of the reinforced soil layer expands the technological capabilities, in particular, ensures the use of materials of different liquid and pigment-like conditions, and the use of
    contactless pathogens of the recorder increases the reliability of the work and the accuracy of the readings and thus improves the quality of the ground reinforcement.
