Tamping method of highway soft base structure

Abstract

The invention provides a tamping method of a highway soft foundation structure. The method adopts a highway soft foundation treatment structure to tamp a highway soft foundation, lifts a tamping column through a cargo boom, adjusts the orientation of the tamping column through a hydraulic press to enable the tamping column to be vertically downward, and then enables the tamping column to be in contact with a soft foundation surface through the direction of the cargo boom. Then a gear motor is started, the gear motor drives a crankshaft to rotate, the crankshaft drives a first rotating shaft torotate through a belt, the first rotating shaft drives a gear to rotate when rotating, the gear is meshed with a tooth row on a lifting arm through teeth so as to drive the lifting arm to lift upwards, and the lifting arm is used for lifting a rammer upwards. According to the tamping method of the highway soft foundation structure, the lifting height of the rammer is changed by adjusting different gears to be meshed with the tooth row and increasing or decreasing teeth, so that the impact force of the rammer is adjusted, and then tamping operation on different soft foundations is 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...

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
