This invention discloses an embankment structure and construction method reinforced by geogrid and EICP, belonging to the field of embankment structure technology. It includes: a road base course, an embankment bearing layer, and a natural soil foundation layer. The natural soil foundation layer serves as the structural support for the embankment and is located at the bottom layer. The road base course bears the upper traffic load and evenly transfers it to the lower embankment bearing layer. The embankment bearing layer bears the upper load transferred from the road base course. This invention improves engineering performance through multi-layered synergistic effects. The core reinforcement layer adopts an innovative spatial grid structure, composed of prefabricated geogrids, obliquely arranged geogrid supports, and rigid load-bearing plates, forming a three-dimensional force transmission network. This overcomes the limitations of traditional reinforcement methods, achieving multi-directional load transfer and uniform distribution. Furthermore, the geogrid supports are arranged at a specific angle, ensuring structural rigidity while avoiding stress concentration.

This invention relates to the field of road shoulder slipforming technology, specifically a slipforming casting device for highway soil shoulders. It includes a top shell with a connecting component fixedly connected to one side for connection to a slipform paver. A mold mechanism is located inside the top shell, comprising two side plates. Multiple guide rails are fixedly connected to the top surface of the top shell, and the tops of both side plates are slidably engaged with these guide rails. In this invention, the road soil is limited by the top shell and mold mechanism, and the road soil is evenly distributed by a dispersing mechanism. The road soil is then vibrated and compacted by the forming mechanism to form a road shoulder. If a defective road shoulder appears, it can be cut and broken by the dispersing mechanism to restore the road shoulder to its original road soil state. The road soil is then pre-compressed by the dispersing mechanism, and then compacted by the forming mechanism, facilitating the reconstruction of the road soil.

The application provides a novel farmland road structure, which is paved on farmland base soil and comprises, from bottom to top, a mesh cloth layer, a water guide grid layer, a sand cushion layer and a solidified soil layer. The mesh cloth layer is covered on the farmland base soil, the water guide grid layer is covered on the mesh cloth layer and comprises an HDPE three-dimensional honeycomb grid, the height of the HDPE three-dimensional honeycomb grid is set as 150±50 mm, the sand cushion layer is filled in the HDPE three-dimensional honeycomb grid, the sand cushion layer is composed of medium coarse sand and / or gravel, and the solidified soil layer is covered on the sand cushion layer. The three-dimensional composite framework structure composed of the water guide grid layer and the sand cushion layer effectively disperses the upper vehicle load to a larger area of the base layer, greatly improves the overall rigidity and anti-deformation capacity of the road, effectively avoids the rut and subsidence problems of the traditional soil road under the rolling of heavy agricultural machinery, and the overlying solidified soil layer further provides a solid and flat driving surface.

The utility model discloses a kind of earth road shoulder leveling devices, it is related to earth road shoulder leveling equipment technical field, including scraping flat plate group, the scraping flat plate group is installed on connecting frame, the connecting frame is installed on the mechanical arm of walking machine, the lower edge of the scraping flat plate group is used to scrape flat earth road shoulder surface, one side of the scraping flat plate group is equipped with first calibration support, first calibration rod is connected on the first calibration support, the first calibration rod can be moved up and down on the first calibration support, the lower end of the first calibration rod can be contacted with road surface. The utility model is contacted with road surface by first calibration rod, so that the height of scraping plate group can be calibrated, so that it can be scraped flat along the expected height to the earth material on earth road shoulder surface.

The utility model belongs to the field of soil shoulder construction technology, specifically provide a road construction soil shoulder paving compaction device, including mobile equipment, push material board, paving assembly and compaction component, mobile equipment is used for driving push material board, paving assembly and compaction component move along the length direction of soil shoulder. In the moving process, the push material department of push material board first pushes the earth material that exceeds the soil shoulder construction area to the inside of soil shoulder construction area, then through paving screw, the earth pile on the top of earth material is scattered, and the top of earth material is changed from pointed pile to relatively flat plane. Finally, compaction component compacts earth material, and the formed soil shoulder is obtained. The application moves forward along the length direction of soil shoulder through mobile equipment, concentrates earth material in the inside of soil shoulder construction area through push material board, then spreads earth material flat through paving screw, and finally compacts earth material through compaction component, which is more high in degree of automation, helps to reduce the labor intensity of workers, and improves construction efficiency.
