Description

Technical Field

[0001] The invention relates to the technical field of soft foundation processing devices, and in particular to a soft foundation dynamic loading reinforcement device. Background Art

[0002] Soft ground refers to a foundation mainly composed of silt, silty soil, backfill, miscellaneous fill or other highly compressible soil layers. This kind of foundation has too much natural water content and low bearing capacity, and is prone to sliding or consolidation settlement under load. The main treatment methods for soft soil foundations are: cushion replacement method, preloading method, compaction method, deep mixing method, high-pressure jet grouting method, grouting method, dynamic compaction method and reinforcement method, etc. Among them, the dynamic compaction method is a method of strengthening the foundation by exerting a greater impact on the foundation through greater pressure and impulse. This method can increase the strength of the foundation, enhance the foundation's ability to resist liquefaction, and greatly reduce and eliminate the collapsibility of loess.

[0003] In the existing technology, a hydraulic compactor is used to compact the soft foundation. After the ground is compacted, grooves will be generated. After the first compaction of the construction site is completed, a bulldozer is required to fill all the grooves, and then a roller is used to compact the surface of the grooves. After the compaction is completed, the hydraulic compactor is used again to perform compaction operations, and the cycle is repeated until the construction foundation is completely compacted. The construction steps are very cumbersome, and the existing hydraulic compactor cannot automatically fill and compact the grooves after the compaction operation. Summary of the invention

[0004] In order to solve the problems in the above-mentioned prior art that the compaction process is complicated and cumbersome, and the workload is large, the present invention provides a dynamic loading reinforcement device for soft foundation.

[0005] To realize the above technical scheme, the present invention provides a dynamic loading reinforcement device for a soft foundation, comprising a trolley, the rear wheel of the trolley is a compaction wheel, and the front wheel is a rubber wheel; a mounting surface is provided in front of the trolley, a first telescopic rod and a second telescopic rod are provided on the mounting surface, one end of the first telescopic rod is hinged to a hydraulic compaction device, and one end of the second telescopic rod is hinged to a leveling mechanism; an auxiliary support rod is rotatably provided above the rubber wheel, and the other end of the auxiliary support rod is hinged to the hydraulic compaction device; a propulsion rod is rotatably provided in front of the auxiliary support rod, and one end of the propulsion rod is hinged to the leveling mechanism.

[0006] Furthermore, the car is a diesel car.

[0007] Furthermore, the leveling mechanism is a soil shoveling device.

[0008] Furthermore, the leveling mechanism is a soil crushing device.

[0009] Furthermore, the end of the shoveling device close to the ground is inclined at 30° to 45° with respect to the horizontal plane.

[0010] Furthermore, the soil crushing device comprises a soil crushing wheel and a soil crushing shovel. The surface of the soil crushing wheel is provided with convex teeth. The soil crushing shovel is arranged behind the soil crushing wheel and is inclined at 130° to 140° with the horizontal plane.

[0011] In summary, the present invention has the following beneficial effects compared with the prior art:

[0012] The present invention provides a dynamic loading and reinforcement device for a weak foundation. After compaction is completed at one position, the leveling mechanism in front of the trolley can be controlled to dig the soil downward, so that the horizontal plane where the trolley is located is consistent with the bottom of the depression compacted by the hydraulic compaction device, and in this process, the leveling mechanism can break the soil in front of the trolley to make the road surface smoother. When the trolley continues to work forward, the rear wheels of the trolley, i.e., the compaction wheels, can compact the road surface to further achieve the effect of loading and reinforcing the foundation.

[0013] In addition, in order to cope with construction environments with relatively solid soil and general soil, the present invention provides two solutions for the leveling mechanism: a soil shoveling device and a soil crushing device, so as to increase the practicality of the present invention.

[0023] When in use, after a position is compacted, the leveling mechanism in front of the trolley 1 can be controlled to dig the soil downwards, so that the horizontal plane where the trolley 1 is located is consistent with the bottom of the depression compacted by the hydraulic compaction device 2, and in this process, the leveling mechanism can break up the soil in front of the trolley 1 to make the road surface smoother. As the trolley 1 continues to move forward, the rear wheels of the trolley 1, i.e., the compaction wheels 3, can compact the road surface to further achieve the effect of loading and reinforcing the foundation.

[0025] As a preferred embodiment, when the soil in the actual construction environment is relatively loose, the leveling mechanism can be replaced by a shoveling device 4.

[0026] As a preferred embodiment, when encountering a construction environment with relatively solid soil, the leveling mechanism is replaced with a soil crushing device 5, which can make it easy for the dynamic loading reinforcement device for the soft foundation to achieve the purpose of the running surface of the trolley 1 and the concave surface being at the same level.

The soil crushing shovel 51 is arranged behind the soil crushing wheel 52 and is inclined at 130° to 140° with the horizontal plane.

[0029] In addition, the rear wheels of the trolley 1 provided by the present invention are replaced with compacting wheels 3, which can increase the weight behind the trolley 1 to balance the weight of the hydraulic compacting device 2 and the leveling device in front of the trolley 1, so that the trolley 1 is more stable during operation.
