SU923825A1 - Depth concrete mixture vibration compactor - Google Patents

Description

The invention relates to compaction. concrete mixes in construction.

The closest to the proposed is a deep vibratory compactor for concrete mixes, which contains a working body with a cross-shaped cross section, on the upper end of which there is a bracket with an exciter of directional oscillations [13.

Disadvantages of the known deep vibrouplotnitelej ¹⁰ are insufficient productivity and Nye impossibility compaction of concrete mixtures in cramped conditions.

The purpose of the invention - increasing productivity and ensuring possibilities ¹⁵ STI compaction of concrete mixtures in cramped conditions.

This goal is achieved by the fact that in the subsurface vibrating compactor containing a working body with a cross-shaped cross section, on the 'upper end of which there is a bracket with the exciter of directional oscillations,

the working body is made curved along a helical line. In addition, the deep vibrator is equipped with additional working bodies attached to the bracket of the exciter of oscillations parallel to the main working body.

FIG. 1 schematically shows a deep vibrator, general view; in fig. 2 - the same, side view.

Deep vibratory compactor consists of a bracket 1 with a pathogen of vertically directed oscillations fixed on it in the form of pendulum vibrators 2 connected to be synchronized by shaft 3 and rigidly connected to bracket 1 by upper ends of the main and additional working bodies made of bayonets 4 of cross-section curved along the screw lines installed in parallel and forming a comb.

traversing 7, suspended from the hook of the lifting means (not shown) ·

The vibratory compactor works as follows. five

Using a crane, the working bodies forming the comb are lowered into a narrow cavity or joint, partially filled with a concrete mix, and vibrators 2 are turned on. Then the concrete mix continues to flow. The compaction of the concrete mix occurs due to the vertically directed oscillations of the cruciate bayonets 4, curved along a helical line. When the concrete is completed, the deep vibrator is lifted by a crane, after which the vibrators 2 are turned off. The oblique arrangement of the faces of the bayonets 4 contributes to the transfer of vertical cocks; the concrete and does not prevent its swelling when removing the working body of concrete.

The application of the proposed vibroplot. It allows the compaction of a concrete mix during its laying in

gaps and joints up to 10-12 m deep, saturated with reinforcement.
