A compacting method for soft base structure of highway

Abstract

The invention provides a method for compacting a highway soft base structure. The highway soft base treatment structure is used to tamp the highway soft base, a lifting arm is used to lift the tamping column, and a hydraulic device is used to adjust the direction of the tamping column, so that the tamping column Vertically downward, then tamp the column through the direction of the boom to make it contact with the soft ground, then start the deceleration motor, the deceleration motor drives the shaft to rotate, the shaft drives the first shaft to rotate through the belt, and when the first shaft rotates, it drives The gear rotates, and the gear meshes with the tooth row on the lifting arm to drive the lifting arm to lift upward, and the lifting arm is used to lift the rammer upward. The present invention adjusts different gears to mesh with the tooth row, and utilizes the function of increasing or decreasing teeth By changing the lifting height of the rammer, the impact force of the rammer can be adjusted, and the compaction of different soft foundations can be completed.

Description

technical field [0001] The invention relates to the technical field of soft ground treatment, in particular to a method for compacting soft base structures of highways. Background technique [0002] When building subgrades in soft soil areas, the main problems are the stability of the soft foundation sliding damage caused by embankment filling loads and the large and long-term settlement. The road soft foundation treatment should be carried out as early as possible, and there is sufficient interval time for the soft foundation to reach Filling construction can only be carried out after the settlement is stable. The common soft foundation treatment method is the compaction method, and the compaction method is mostly completed by a compactor; [0003] The Chinese patent discloses a tamping machine for building construction. The patent application number is CN201821944722.2. A tamping device, and a connection plate is fixedly installed on one side of the inner cavity of the ta...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned device can regularly tamp the subgrade, the road tamping area is large and there are differences in the subgrade, resulting in different gravity required for tamping in each area. Some areas can be simply tamped, and some areas also require larger In addition, a large amount of dust will be generated during the compaction process, which will easily affect the sight of the operator. During the compaction process, the gravel will be splashed by the impact of the rammer, which will easily cause damage to the surrounding people and equipment. The compaction seat is easy to adhere to the soil, resulting in uneven compaction force
