Description

one

FIELD OF THE INVENTION The invention relates to the construction of a solid concrete construction foundation for concrete bases such as dams.

The closest technological solution to the invention is a device for the deep compaction of concrete mixes, which contains the traverse and vibrators suspended deep into it. Traverse is made in the form of a rigid p ..

The disadvantages of this device are the low efficiency of compacting the concrete and the inconvenience of servicing when concreting the upper part of arched dams and similar structures.

The purpose of the invention is to intensify the compaction process and ease of maintenance.

This goal is achieved by the fact that in a device for deep consolidation of betsinss mixtures containing a traverse and immersion vibrators suspended from it, the traverse is made of a composite of sections connected to each other using hinges with a vertical axis , and these fixtures are made in the form of lanyards.

FIG. 1 shows the device in the unfolded position of the crosshead sections (uniform arrangement of vibrators), general view; in fig. 2 - the same, in the folded position of the sections (two-row arrangement of vibrators); in fig. 3 is the same plan of FIG. 2,

The device for deep compaction of concrete mixes consists of a traverse, made in the form of composite sections 1-3, interconnected by hinges 4 with a vertical axis. The traverse is suspended from to the lifting mechanism by means of a cable or chain 5. To the traverse at the outer points of its extreme sections 2 and 3 (there may be more of them) and at the points of attachment of the hinges 4 the vibrator 6 is suspended.

Sections 2 and 3 are fixed relative to the central section 1 with the help of

lanyards 7 and 8, regulating their position (at any angle to section 1).

Convenience for deep compaction of concrete mixes works as follows,

By adjusting the length of the lanyards 7 and 8, sections 1 - 3 are installed in a single mode (Fig. 1) or double (Fig. 2, the position of the vibrators 6, turning sections 2 and 3 along arrows A. The device is immersed in the concrete mix and the vibrators are driven.

The present invention allows to intensify the compaction process and to provide a more convenient service for concreting the corner parts of arched dams and similar structures.

Claims (2)

Claims of the invention: 1. A device for deep compaction of concrete mixes containing a traverse and immersion vibrators suspended from it, characterized in that, in order to intensify the process of compaction and ease of maintenance, the traverse is made composite of each other connected by means of hinges with vertical the axis of the sections, the extreme of which are provided with clamps of their position relative to the central section. 2. The device according to claim 1, of which is that the clamps of the outer sections are made in the form of lanyards. Sources of information taken into account in the examination 1.
