Technical Field

[0002] At present, flat plate rammers, frog-type rammers and vibrating rollers are used for backfill compaction. This type of compaction is more convenient for flat terrain and unobstructed surroundings, but it is more difficult to compact the backfill near the bottom slope of a counterweight retaining wall. Manual compaction is slow and uneconomical.

[0003] It is necessary to summarize the design and research of a flat plate rammer device suitable for backfilling of inverted slope retaining walls.

[0004] At present, existing technologies that can be used for slope tamping include CN202122225488.6_new multi-angle hydraulic tamping hammer, which is a vertical tamping hammer equipment with a small working surface at the lower end and low efficiency in tamping the backfill of reverse slope retaining walls; CN202222312052.5_slope tamping bucket and CN202320739905.5_a slope tamping device for water conservancy construction, whose structure is essentially a plane tamping equipment, but the angle of use is an inclined angle.

[0005] Therefore, based on the flat plate tamping machine product, how to transform it so that it can not only meet the flat tamping needs in most occasions, but also temporarily solve the backfill needs of the reverse slope retaining wall is a relatively practical and economical improvement demand. Utility Model Content

[0006] The purpose of the utility model is to address the deficiencies of the prior art and to provide a flat plate tamping machine device suitable for backfilling of inverted slope retaining walls that can meet the needs of backfilling and tamping of inverted slope retaining walls and the needs of flat tamping.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a flat plate tamping machine device suitable for backfilling of reverse slope retaining wall, comprising a flat plate tamping machine and a slope tamping assembly detachably mounted on the bottom plate of the flat plate tamping machine;

[0008] The bottom plate of the flat plate rammer is provided with screw holes around it;

[0009] The slope tamping assembly includes a structure with a slope formed by welding high-strength steel plates. The cross section of the slope tamping assembly is triangular, wherein the hypotenuse of the triangle corresponds to the slope panel, and the longer right-angled side of the triangle corresponds to the connecting plate. The connecting plate is provided with matching screw holes corresponding to the screw holes on the bottom plate of the flat plate tamping machine. The connecting plate is locked with the bottom plate of the flat plate tamping machine by bolts.

[0010] The slope panel is inclined in an inclination direction from one lateral side of the flat plate rammer to the other side.

[0011] Preferably, in the cross-sectional dimensions of the slope tamping assembly, the length ratio of the longer right-angled side to the shorter right-angled side is 1:0.35.

[0012] Preferably, the slope panel in the slope tamping assembly is made of high-strength manganese steel plate.

[0013] Preferably, other surface materials in the slope tamping assembly are made of high-strength manganese steel plates.

[0014] Preferably, the connecting plate is connected to the bottom plate of the flat plate rammer by high-strength bolts, and double nuts are provided to prevent loosening.

[0015] Preferably, a web plate is provided between the slope panel and the connecting plate in the slope tamping assembly.

[0016] Preferably, there are at least two webs, and the thickness of the web is less than or equal to the thickness of the slope panel.

[0017] Preferably, the length of the slope panel is ≥500 mm and the width is ≤400 mm.

[0018] Preferably, the front and rear edges of the slope panel are raised.

[0019] Preferably, the bolt holes between the connecting plate and the bottom plate of the flat plate rammer are located in the lateral side areas.

[0020] The utility model has substantial features and progress compared to the prior art. Specifically, the utility model opens a hole on the bottom plate of the flat rammer, and installs a slope rammer assembly made of a high-strength steel plate with a sloped surface by bolt connection. When constructing the reverse slope backfill at the bottom of the retaining wall, the bottom surface of the rammer is tilted and the side surface of the rammer is parallel to the reverse slope retaining wall, so that rapid tamping can be achieved without damaging the retaining wall.
