Embodiment 1

[0064] The mobile device is equipped with a high-pressure water pump, a high-pressure mud pump 2, and a slurry tank 1 with solidified slurry. The guide frame 5 is kept vertically stable through the support rod 3 and the auxiliary support rod in front of the vehicle. The vibrating hammer 4 and the vibrating rod 6 The guide frame 5 can be moved up and down by the control system inside the moving device. When the mobile device carries the slurry bucket 1, high-pressure water pump and high-pressure mud pump 2, vibratory hammer 4, guide frame 5, and vibrating rod 6 to the hole to be reinforced, start the vibratory hammer 4, high-pressure water pump and The high-pressure water pump inside the high-pressure mud pump 2, and adjust the vibrating hammer 4 to a higher vibration frequency. 6 sprays out from the bottom; the vibrating rod 6 sinks along the guide frame 5 according to the design speed under the action of the control system in the mobile device; when the vibrating rod 6 reache...

Abstract

The device and method for deep resonant compaction and reinforcement of miscellaneous fill foundation, after sinking the vibrating rod into the soil, adjust the frequency of the vibrating hammer to the resonant frequency of the vibrating rod-soil system, and use the principle of resonance amplification to effectively transfer the vibration energy to the deep miscellaneous Filling, forming a resonant compacting area of ​​miscellaneous fillings, plus the mixed area of ​​solidifiable slurry and miscellaneous fillings for auxiliary reinforcement, the vibrating hammer drives the vibrating rod to freely fall to compact the compacted area formed by the loose soil inside the vibrating hole Reinforce miscellaneous fill foundation; effectively solve the shortcomings of traditional methods such as poor effect of reinforcing deep miscellaneous fill, low economic benefits, and complicated construction techniques.

Description

technical field [0001] The invention belongs to the technical field of miscellaneous fill foundation treatment, and in particular relates to a device and method for deep resonance and compact reinforcement of miscellaneous fill foundation. Background technique [0002] With the rapid development of urban economy and the gradual increase of population, people's demand for land is increasing, and the construction land is becoming increasingly scarce. At the same time, the rapid development and renewal of my country's urbanization has made the distribution of miscellaneous fill soil layers composed of a large amount of construction waste, industrial waste or domestic garbage more and more extensive, resulting in some engineering constructions having to be carried out on miscellaneous fill soil layers. However, the foundation of miscellaneous fill is complex in nature, and there are problems such as large thickness variation, hard surface soil, low bearing capacity, large porosi...
