Aeolian sand liquefaction ballasting earthing reinforcement equipment and ballasting method

Abstract

The invention discloses aeolian sand liquefaction ballasting earthing reinforcement equipment and a ballasting method. The aeolian sand liquefaction ballasting earthing reinforment equipment comprises a movable shell, a feeding port is formed in the top of the shell, a coarse material discharging port is formed in one end of the shell, a closing mechanism is arranged on the coarse material discharging port, a compaction mechanism is arranged at the other end of the shell, a counterweight mechanism is arranged on the compaction mechanism, a crushing mechanism and an inclined screen are mounted in the shell, and a discharge pipe is mounted on a bottom plate of the shell; raw material broken stones fall on the crushing mechanism and fall on the screen after being crushed, oversize materials move to the coarse material discharging port, undersize materials fall on the discharging pipe, the oversize materials are discharged to liquefied aeolian sand through the coarse material discharging port, the equipment is pushed to flatten the oversize materials, an outlet in the lower end of the discharging pipe is opened, the undersize materials are discharged, the equipment is moved, the undersize materials are flattened, a shovel plate is unloaded, a pressing roller is pressed on the flattened undersize materials, and the equipment is moved to compact the liquefied aeolian sand and the flattened broken stones. The reinforcing equipment has a plurality of functions, the number of operators is greatly reduced, operation is easy and flexible, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of sand liquefaction reinforcement equipment, and relates to a wind-blown sand liquefaction compaction reinforcement equipment; the invention also relates to a method for using the reinforcement equipment to press and weigh liquefied wind-blown sand. Background technique [0002] The liquefaction phenomenon of aeolian sand along the railway means that the sand or silt tends to be dense, resulting in a sharp increase in pore water pressure. The sharply increased pore water pressure is too late to dissipate, reducing the effective stress. When the effective stress disappears completely, the sand particles are partially or completely suspended. At this time, the shear strength of the soil is equal to zero, forming a "liquid" phenomenon, which makes the foundation next to the railroad track unstable and poses a greater threat to the railroad track. [0003] In order to eliminate the liquefaction phenomenon of ae...

AI Technical Summary

Problems solved by technology

However, the pressure-reinforced soil reinforcement equipment in the prior art usually uses a variety of equipment to consolidate the liquefied sand through a large number of manual operations. The operation is cumbersome, time-consuming and labor-intensive, and does not have the function of flexible operation.
