The invention relates to the construction and can be used for compacting soil in trenches, pillars and other hard to reach places.

Known vibratory plate, including unbalanced mechanism, the sealing plate and the drive unbalanced mechanism (Dotsenko A.I. Construction machinery and fundamentals of automation. - M.: Higher school, 1995. - S-261; patent No. 2236496 from 20.09.2004).

A disadvantage of this device when soil compaction in trenches and other hard to reach places is the need to raise the slab before laying the next layer of soil, the complexity of the control plate in the trench.

For the prototype accepted the plate attached to the handle excavator backhoe through spring dampers (Manual on the construction of the subgrade of roads. - M.: Transport, 1982. - P.42-44).

A disadvantage of this device is the need to use other equipment for soil compaction in the lateral sinuses in the presence of the pipeline trench, and the inability to use compactors until it is over the tube filled with protective soil layer thickness of 0.5 m, and the need for additional machine for levelling soil before compaction.

The purpose of the invention is the use of one machine when soil compaction in trenches and in other hard to reach places, the simplification of the institutions and the cost of the work.

This objective is achieved in that the plate is mounted in a special frame and attached thereto with the help of ropes and cylinder. The frame is fixed instead of the bucket on the handle excavator type reverse mechanical shovel hinge, and it can be rotated with respect to its angle of +/-20 degrees. Frame made of profiled metal, the sides of her closed iron sheets, and lateral angles made ribs. The frame has lugs for fixing compactors in the upper position, allowing the raising of it in the upper position to form a single plane with a frame that will allow you to use it as razravnivalis.

Figure 1 shows the proposed device, side view; figure 2 is a view of the device from below.

The device consists of a frame 1, 2 compactors, rope suspension 3, the cylinder 4. In the upper part of the frame is made of lugs 5, which serve for fastening the frame to the handle excavator type backhoe and allow it to pivot relative to the handle at an angle of +/-20 degrees. The frame 1 has the lugs 7, which rests on the plate 2 when lifting it to the top position using the hydraulic cylinder 4 before levelling of ground, with the bottom of the frame and the plate form a single plane. For leveling soil the sides of the frame are closed by iron sheets 8 and on the side corners have four R the wall 6.

Device for soil compaction works as follows. After laying in the trench portion of the ground plate lifted to the upper position and produce ground levelling. If the trench is a pipeline or other equipment, not allowing vibratory compaction, the first layers of compacted soil a static method using the frame from inside the stove. Subsequent layers after laying and levelling of soil compacted vibration method, the push plate from the frame using a hydraulic cylinder.

The proposed device allows to simplify the organization and the cost of work during compaction in trenches in the presence of pipelines and other hard to reach places.
