Description

Technical Field

[0001] The present invention relates to the technical field of earthwork engineering, and specifically to an earthwork filling device for engineering construction. Background Technique

[0002] Foundation earthwork engineering mainly involves earth excavation, filling, and soil improvement before foundation treatment. Earthwork filling mainly involves earth filling and compaction. During the earthwork filling construction process, layered filling and compaction are adopted. The filling is mainly operated by an excavator. After filling, a roller is mainly used for rolling compaction, and a roller with a vibrating compaction wheel is mostly used to ensure the compaction degree. For example, the Chinese invention application with the publication number CN117966549A discloses a vibrating compaction device for earthwork backfilling and its use method. The vibrating compaction device for earthwork backfilling includes a machine body and a compaction wheel. A scraper and a transfer box are arranged on the machine body. One end surface of the scraper is attached to the surface of the compaction wheel. Two water tanks are detachably connected to the transfer box. A hose penetrates through an outer wall of the transfer box. One end in the length direction of the hose communicates with a spray head, and the liquid outlet end of the spray head faces the surface of the scraper. A water pumping member for driving water flow towards the spray head is arranged on the hose. An adjusting mechanism is arranged on the transfer box. The adjusting mechanism is used to drive one end of the hose extending into the inner cavity of the transfer box to move and make one of the two water tanks communicate with the hose. However, there are the following defects in the compaction construction during the current earthwork filling construction: During compaction construction, it is difficult for the roller to enter narrow areas and the corners of the earthwork for compaction. During such construction, workers need to use a rammer to manually compact these positions, which leads to a large consumption of labor and low efficiency in the overall construction. In addition, the currently used vibrating roller for compaction vibrates in the vertical direction of the compaction wheel. During compaction, the soil in the same layer is unevenly stressed, resulting in a decrease in compaction uniformity and affecting the construction quality.

[0003] Therefore, we propose an earthwork filling device for engineering construction to solve the above problems. Summary of the Invention

[0029] When the present invention is in use, after the soil layer is filled by equipment such as a forklift, the device enters the surface of the soil layer, and the front roller structure 3 and the rear roller structure 4 are used to roll the soil material. When the rolling position is close to the corner of the earthwork, the adjusting arm structure 21 in the corner compaction mechanism 2 will drive the ramming structure 23 to move to the corner. At the same time, the angle adjustment structure 22 adjusts the angle of the ramming structure 23 to make it fit the soil material, so as to compact the corner position while rolling. When moving to a narrow position during construction, the adjusting arm structure 21 is also used to drive the ramming structure 23 to move to the narrow position for compaction; the present invention adds a corner compaction mechanism 2. The adjusting arm structure 21 can drive the ramming structure 23 to move in multiple directions, and at the same time, the height and horizontal position of the ramming structure 23 can be changed by the telescoping of the first sliding column 2115 and the second sliding column 2117. In this way, the ramming structure 23 can be conveniently moved to a narrow area or a corner area, and the angle adjustment structure 22 can change the angle of the ramming structure 23 by using two fourth hydraulic push rods 2210, so that the bottom of the ramming structure 23 fits the soil material, replacing manual ramming to complete the compaction work in these areas, reducing manual consumption, and can simultaneously complete the compaction work in some corner areas when the equipment is rolling and compacting, improving the overall construction efficiency; in the rear roller structure 4 of the present invention, two driven shafts 414 carrying second excitation eccentric blocks 415 are arranged on both sides. In this way, when the driven shafts 414 rotate, they will vibrate in the diagonally downward direction, and cooperate with the vertical vibration compaction of the front roller structure 3 to perform multi-directional vibration compaction on the soil body. In this way, the soil body is more evenly stressed during the entire rolling process, and the compaction uniformity of the soil body is improved.
