Abstract

FIELD: construction.

SUBSTANCE: method to pour a concrete mix under process equipment at the final stage of its assembly includes installation of a curb along the foundation contour and an accumulating tray with submersible vibrators included in it. Vibration treatment of the concrete mixture in the process gap between the equipment stand and the foundation is carried out on the entire way of its movement from the accumulating tray to the vibration shell by means of rods placed along the entire area of pouring, ends of which are fixed in a rigid vibration shell, located at the equipment side opposite to the accumulating tray.

EFFECT: higher efficiency of works due to less time spent to fill a process gap with a concrete mix, provision of even distribution of density of a concrete mixture along entire area, higher strength of poured concrete, no limitations in dimensions and configuration of equipment in plan.

Description

The proposed method relates to the field of installation of technological equipment and can be used when pouring concrete mixture under the equipment.

Known methods of pouring concrete mixture under technological equipment by vibration transportation using vibratory trays or vibratory feeders (see V. S. Balitsky, A. S. Marchenko. 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 mixture over the entire area of the filled space.

The closest technical solution to the proposed invention is a method of pouring concrete mixture under technological equipment (MSN 188-68 MMSS USSR "Instructions on the unattended installation of chemical industry equipment" / Central Bureau of Technical Information. - M., 1968), including the installation of formwork along the foundation contour , installation based on the foundation of the storage tray, incorporating submersible vibrators, vibration processing of the concrete mixture in the storage tray.

The disadvantages of this method are limited technological capabilities, i.e. low spreading rate of the concrete mixture in the gap between the equipment bed and the foundation, the inability to uniformly supply concrete mixture over the entire area of the poured space with large equipment dimensions.

The problem to which the present invention is directed, is to expand the technological capabilities of using the method of pouring concrete mixture under technological equipment due to vibration processing of the mixture over the entire area of the technological gap between the supporting part of the equipment to be mounted and the foundation to increase the mobility of the mixture and achieve the necessary uniformity of concrete density in the grout space.

The essence of the invention lies in the fact that the method of pouring concrete mixture under technological equipment includes the installation of formwork along the contour of the foundation and the storage tray with submersible vibrators included in it, as well as vibration processing of the concrete mixture along its entire path in the gap by means of rods placed in it at a distance of 200-300 mm from each other, the ends of which are fixed in a rigid vibration mount located on the side of the equipment opposite to the drive tray, and the axis of the rods is directed to pairs Along the direction of movement of the concrete mixture.

The method of pouring concrete mixture under the technological equipment at the final stage of its installation is illustrated by the drawing, where in Fig.1 - shows a General view of the method.

The method of pouring concrete mixture under technological equipment is as follows. At a certain distance from the bed of the equipment 1 mounted and verified from the point of view of installation accuracy, the formwork 2 is assembled, the upper level of the latter being higher than the mark of the supporting part of the bed 8. Then, rods 5 are placed over the entire space between the foundation and the equipment with a pitch of 200-300 mm . Then, on one side of the equipment, resting on the foundation 5, a receiving tray-drive 3 is mounted with the submersible vibrators 4 included in it. On the side of the equipment opposite the tray, a rigid vibration mount 7 is installed, in which the ends of the rods are fixed. A vibrator 9 is rigidly connected to the cage, which through it informs the rods of the longitudinal vibrations 10 (in a plane parallel to the horizontal surfaces of the bed and foundation). Next, the supply of concrete mixture 6 to the storage tray begins with the simultaneous inclusion of immersion vibrators in the tray, and then the vibrator located on the clip. The feed is conducted continuously, constantly maintaining the level of the mixture in the tray above the mark of the supporting part of the equipment bed. The flow is stopped when the concrete mix appears on the opposite side of the technological gap from the tray, and the surface mix of the concrete mix should be higher than the mark of the supporting part of the equipment. After stopping the supply of concrete mixture, the rods continue to vibrate until the required density of concrete is obtained in the technological gap. Then the vibrator is disconnected, the clip is removed, the storage tray with immersion vibrators is dismantled. The rods leave gravy in the concrete body, which, when transferring the mass of equipment through the gravy to the foundation, acts as reinforcement.

The proposed method has the following advantages over known solutions:

- the possibility of pouring concrete mixture under technological equipment of any size and configuration in the plan;

- increasing productivity by reducing the time it takes to fill the technological gap with concrete mix due to vibration processing of the entire volume of concrete mix in the gap;

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

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