Description

Technical Field

[0001] The utility model relates to an earthwork compaction device for municipal engineering construction, belonging to the technical field of municipal engineering. Background Art

[0002] Municipal engineering, also known as municipal infrastructure engineering, refers to the civil engineering, pipeline, and equipment installation projects of urban roads, public transportation, water supply, drainage, gas, heating, gardens, environmental sanitation, sewage treatment, garbage treatment, flood control, underground public facilities, and their ancillary facilities.

[0003] Chinese Patent (Publication No.: CN 216765827 U) discloses an earthwork compaction device for municipal engineering construction, including a device vehicle body. A rolling cylinder is rotatably connected to the lower part of the front side inside the device vehicle body. Multi-faceted chucks are fixedly arranged on both sides of the rolling cylinder. A number of dial grooves are evenly arranged along the radial direction on the multi-faceted chucks. The outside of the multi-faceted chucks is rotatably connected to the inner wall of the device vehicle body. A support fixing frame is arranged at the rear side of the rolling cylinder. A turning dial groove rod is rotatably arranged at the lower end of the support fixing frame. The turning dial groove rod is rotatably arranged and is in sequential transmission cooperation with the dial grooves.

[0004] This utility model overcomes the shortcomings of the prior art, has a reasonable structure, compacts the earthwork during travel, with tight compaction, small volume, and convenient operation. However, in actual use, there are many factors affecting earthwork compaction. One of them is the water content of the earthwork. Under the same compaction work, the water content of the filled soil has a direct impact on the compaction quality. For relatively dry soil, due to the large frictional resistance between particles, it is not easy to compact. When the water content exceeds a certain limit, the pores between soil particles are filled with water and are in a saturated state, and it cannot be compacted either. The existing earthwork compaction devices lack a device capable of changing the water content in the earthwork, and it is also difficult for the existing compaction devices to adjust according to the water content of the filled soil and select a suitable compaction method, resulting in low compaction work efficiency.

[0005] Therefore, an earthwork compaction device for municipal engineering construction is proposed. Content of the Utility Model

[0031] Embodiment 2

[0032] In one embodiment, diversion plates 9 are fixedly connected to both the left and right sides inside the water storage tank 701. The diversion plates 9 are triangular in shape. A limiting plate 10 is fixedly connected inside the carriage 6.

[0033] By providing the diversion plates 9, the water inside the water storage tank 701 can be diverted. By providing the limiting plate 10 and the slider 11, the stability of the toothed plate 805 during movement can be improved. By providing the water absorption layer 12, the moisture in the filled soil can be absorbed to improve the moisture content of the filled soil.
