Description
Technical Field
[0001] The invention relates to the technical field of construction devices, in particular to a ditch compacting device for highway engineering construction and a construction method thereof. Background Art
[0002] In the complex construction process of highway construction, a crucial link is to carefully plan and dig ditches on both sides of the road. The main function of these ditches is to effectively collect and transport rainwater generated by rainfall to ensure smooth drainage and driving safety of the road. When constructing ditches, a step that cannot be ignored is to thoroughly compact them, which is directly related to the stability and service life of the ditch structure. Given that the design of ditches often has a relatively narrow cross-section, traditional compaction methods are difficult to use. Therefore, the construction team tends to use more flexible and adaptable small compaction equipment to complete this task. As a typical representative of this type of equipment, the frog tamping machine has become the preferred tool for ditch compaction operations due to its small size and easy operation. However, although the frog-type rammers that are widely used at present can compact the bottom of the ditch efficiently and enhance the bearing capacity of the bottom, they are unable to meet the compaction requirements of the ditch side walls. As the key part supporting the entire structure, the ditch side walls will face the risk of collapse due to the strong vibration effect when the frog-type rammer is performing bottom operations if they are not fully compacted. This will not only seriously affect the construction progress, but may also pose a safety hazard to the surrounding environment and construction personnel. Therefore, how to achieve effective compaction of the ditch side walls has become a technical problem that needs to be urgently solved in the current highway construction. To this end, we propose a ditch compaction device and a construction method for highway engineering construction. Summary of the invention
