Description

[Technical field]

[0001] The present invention belongs to the field of compaction equipment technology, and in particular to a width-adjusting compaction structure. [Background technology]

[0002] With the continuous expansion of the scale of construction of China's high-speed railway, the construction of high-speed railway crossings is increasing. At present, the construction of high-speed railway crossings mainly adopts small compaction equipment and manual soil-raising methods. Conventional small compaction equipment cannot achieve width-adjustment compaction because the dampers of the equipment are installed on both sides of the frame, and the effective compaction range is about 10 cm from the structure, so manual soil-raising is required for the area within 10 cm. However, when performing manual soil-raising, it is difficult to control the degree of compaction, which is likely to damage the structure and waterproof layer, and is likely to cause settlement problems due to water infiltration in the width-adjustment area. In addition, since the thickness of the pavement layer of the crossing is controlled manually, the control precision is not high, and problems such as uneven subsidence of the roadbed and deformation of the roadbed are likely to occur.

[0003] Chinese patent (CN102747668A) discloses a vibrating wheel of a road roller that can be converted into circular vibration, oscillating or compound vibration. As can be seen from the structure of this patent, a frame and damper are provided on the left and right sides of the steel wheel, and the presence of the frame and damper prevents the steel wheel from performing width compaction during the compaction process.
