Description

Technical Field

[0001] The utility model relates to the technical field of vibrators, and in particular to a vibrator suitable for penetrating a hard layer. Background Art

[0002] The vibrator is a special machine used in vibratory construction. It generates horizontal vibration force to vibrate the filler and surrounding soil, thereby improving the bearing capacity of the foundation, reducing settlement, increasing foundation stability, and improving the ability to resist earthquake liquefaction. Vibratory mooring piles are a composite foundation treatment technology that allows the presence of prestressed steel strands and pile bottom anchor plates for post-tensioning in the pile body; combined with the jet grouting pile construction technology, an enlarged head similar to the expanded bottom pile will be formed at the bottom of the pile body above the anchor plate during pile construction to improve the pull-out resistance of the pile body, which not only overcomes the weakness of vibratory crushed stone piles that lack pull-out resistance, but also has a higher pull-out resistance.

[0003] However, the eccentric blocks inside the existing vibrators are all semi-cylindrical. In order to reduce the wear of the eccentric blocks, they are arranged in a cavity filled with lubricating oil. Centrifugal force is generated during rotation to vibrate and compact the foundation. However, the semi-cylindrical eccentric blocks will stir the oil during rotation, resulting in a certain amount of power waste and increased working costs. Utility Model Content

[0018] The beneficial effects of the utility model are:

[0019] 1. In the utility model, the vibro-compactor drives the eccentric block to rotate through the motor, generating horizontal vibration force to vibrate the filler and the surrounding soil, so as to improve the bearing capacity of the foundation, reduce the settlement, increase the stability of the foundation, and improve the ability to resist earthquake liquefaction.

At the same time, this arrangement method can facilitate material guiding. The top of the vibrating head is matched and plugged with the connector through the keyway provided. When the vibrating head is sent to a predetermined depth of the soil, it can be directly separated from the vibrating body under the action of its own weight and soil pressure.
