Abstract

The invention makes it possible to improve the quality of laying the concrete mix when erecting wall structures in the ground. The device includes a receiving funnel 1, a flexible transporting tube, in the lower part of which vibrators 3 are attached, and blades 4 above the vibrators. The vibrators are placed on two opposite sides of the tube in a plane, perpendicular to the wall plane, and their unbalances are the same and opposite The angled sides of the rotation allow the concrete mix W to vibrate in the direction of the wall. 3 il. y 00 cd ff-5 .d

Description

The invention relates to the construction and is intended for feeding, laying and compaction of the concrete mix during the construction of a monolithic wall in the ground,

The purpose of the invention is to improve the quality of the concrete mix by vibrating it in the direction of the wall.

FIG. 1 shows the proposed device, the cut; in FIG. 2, section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The device contains a receiving funnel 1J, a transporting pipe 2, two vibrating pipes 3 fixed on its lower part and external radial blades 4. The transporting pipe 2 can be continuous flexible, for example plastic, or composed of Sections interconnected by means of flanges with an elastic gasket 5 between them. The vibrators are fixed on two opposite sides of the tube 1 in a plane perpendicular to the plane of the wall. The balancers of the vibrators 3 have the same and oppositely directed angular rotational speeds.

The device works as follows

Transport pipe 2 with a receiving funnel 1 is installed with a crane to a predetermined mark above the place of laying the concrete mix in the trench. The concrete mixture is fed into the receiving hopper and the vibrators 3 are turned on. Under the action of vibration, the mixture passes into the state of a strong liquid and flows out of the pipe. Due to the fact that the Unbalances of a pair of vibrators rotate in different directions with identical and oppositely directed angular velocities, the tube-vibrators system emits vibrations along the axis of the wall. The shape of the emitted waves is close to flat.

The flat nature of the emitted waves increases the area of effective compaction to 2-2.5 m for concrete mixes with a range of mobility from 1-4 to 6-10 cm. Received VIBRATION PI location

The invention relates to the construction and is intended for feeding, laying and compacting a concrete mix during the erection of a monolithic wall in the ground. The purpose of the invention is to improve the quality of laying of the concrete mix by vibrating it in the direction of the wall. 1 shows the proposed device, the cut; in FIG. 2, section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1. The device contains a receiving funnel 1J, a transporting pipe 2, two vibrating pipes 3 fixed on its lower part and external radial blades 4. The transporting pipe 2 can be continuous flexible, for example plastic, or composed of Sections interconnected by means of flanges with an elastic gasket 5 in between. The vibrators are fixed on two opposite sides of the tube 1 in a plane perpendicular to the plane of the wall. The balancers of the vibrators 3 have the same and oppositely directed angular rotational speeds. The device works as follows: The Transport Pipe 2 with the receiving funnel 1 is installed with a crane to a predetermined mark above the place of laying the concrete mix in the trench. The concrete mixture is fed to the receiving hopper and the vibrators 3 are turned on. Under the action of vibration, the mixture passes into the state of fine liquid and flows out of the pipe. Due to the fact that the imbalances of a pair of vibrators are rotated in opposite directions with identical and oppositely directed angular velocities, the tube vibrators system emits vibrations along the axis of the wall. The shape of the emitted waves is close to flat. The flat nature of the emitted waves increases the area of effective compaction to 2-2.5 m for concrete mixes with a range of mobility from 1-4 to 6-10 cm. The received placement of vibro405: t tori, the presence of blades and flexibility of the pipe 2 allows to achieve alternating signs angular or sinusoidal oscillations decreasing to the top by the magnitude of the diagram, which in turn avoids stratification, if necessary, the use of concrete mixtures of high mobility (6-10 cm). The advantages of the proposed device are to improve the strength characteristics of the material, the ability to use low-mobility mixtures with a draft of 1-4 cm cone, which improves the quality of structures, leads to savings in ensuring the possibility of using the device in highly reinforced structures, in increasing the area of effective compaction, which allows to increase the size of the concrete grippers and reduce the number of seams between them. The invention The device for feeding, laying: and and compacting the concrete mix into a wall in a 1-sleeved structure, including a receiving funnel and a transporting tube with a vibrator rigidly fixed on its lower part, so that in order to improve the quality of the concrete mix by vibrating it in the direction of the wall, the transport pipe is equipped with an additional vibrator, while the main and additional vibrators are fixed on two opposite sides of the lower part of the pipe in a plane perpendicular to The second plane of the wall, with de balances of the vibrators having the same and oppositely directed angular rotational speeds, and on the surface of the tube, external radial blades are made above the vibrators. moreover, the pipe is made either flexible or composite of sections interconnected by means of flanges and elastic gaskets between them.
