The proposed method relates to the field of installation of technological equipment and can be used in the gravy concrete mix for equipment.

Known methods gravy concrete mix under technological equipment by vibrating transportation using webroot.com or vibratory feeders (see Usebility, Assurance. Concrete work. - Kiev: Budivelnik, 1977. - P.59).

The disadvantages of these methods are the need to use bulky equipment, the inability to ensure uniform compaction of the concrete mix over the entire area fill space.

The closest technical solution of the present invention is a method gravy concrete mix under technological equipment (sit 188-68 MMS the USSR "Instructions besplatna installation of equipment for the chemical industry / Central Bureau of technical information. - M., 1968), including formwork Assembly along the contour of the Foundation, installation leaning on the Foundation of the tray of the drive, having in its composition immersion vibrators, vibrating treatment of the concrete mixture in the tray of the drive.

The disadvantages of this method are the limited technological capabilities, i.e. low velocity of propagation of the concrete mixture in the gap between the frame of the equipment and the fundamental is the fact that the impossibility of a uniform supply of concrete mixture over the entire area add space for large size equipment.

Task to be solved by the present invention is directed, is the expansion of technological possibilities of using the method of gravy concrete mix under processing equipment due to the vibration treatment of the mixture over the entire area of the technological gap between the base part mounted equipment and the Foundation for increasing the mobility of the mixture and to achieve the necessary uniformity of the density of the concrete in polivoces space.

The invention consists in that the way the gravy concrete mix under processing equipment includes forming the contour of the base and tray-drive by its constituent immersion vibrators and vibrating treatment of the concrete mixture all the way of its movement in the gap by hosting the rods at a distance of 200-300 mm from each other, the ends of which are fixed in a rigid vibraimage located on the opposite side of the tray-drive side hardware, with the axis of the rods are parallel to the direction of movement of the concrete mixture.

Method pour the concrete mix under technological equipment at the final stage of installation is illustrated cher the hedgehog, which figure 1 - is a perspective view of the method.

Method pour the concrete mix under technological equipment is carried out as follows. At a certain distance from the frame mounted and balanced from the point of view of accuracy of the installation equipment 1 collect the casing 2, with the upper level must be above the level of the supporting part of the frame 8. Next, over the entire area of the space between the Foundation and the equipment place the rods 5 in increments of 200-300 mm, Then on one side of the equipment supported on the base 5 is mounted a receiving tray drive with 3 included in its composition immersion vibrators 4. On the opposite side of the tray-side equipment set hard wibrobia 7, in which are fixed the ends of the rods. With the yoke rigidly connecting the vibrator 9, through which it informs the terminals of the longitudinal oscillations of 10 (in a plane parallel to the horizontal surfaces of the frame and Foundation). Then start feeding the concrete mix 6 in the tray storage with simultaneous inclusion of immersion vibrators in the tray, and then the vibrator is located on the holder. Flow are continuously maintaining a constant level of the mixture in the tray above the level of the supporting part of the base equipment. The flow stops when the concrete mix on the opposite side of the tray-side technology for the ora, and mark the surface of the concrete mix should be above the level of the supporting part of the equipment. After cessation of the concrete mix continue vibrating rods until a desired density of the concrete in the technological gap. Then disconnect the vibrator, remove the clip, remove the tray drive with immersion vibrators. The rods are left in the body of concrete gravy that when mass transfer equipment through the gravy on the Foundation perform the role of reinforcement.

The proposed method has the following advantages over the known solutions:

- ability to pour concrete mix under processing equipment in all sizes and configuration to the plan;

- increase productivity by reducing time to fill the technological gap with concrete due to the vibration treatment of the entire volume of concrete mix in the gap;

- uniform distribution of density of the concrete mix over the entire area of gravy;

- increase the strength of concrete gravy due to its reinforcement rods.
