Description

Technical Field

[0001] The utility model belongs to the field of municipal engineering construction, in particular to a foundation pit excavation device. Background Art

[0002] Foundation pit excavation is a common construction process in municipal construction. Among them, the foundation pits for street lamp foundations and seedling planting are standard size foundation pits. The size of the foundation pits is relatively fixed according to the size of lamps and seedlings. The foundation pits are small and numerous, and most of the soil for construction is green soil or silt, which is soft. At present, in the construction of street lamp foundations and seedling planting, excavators or manual labor are generally used to dig the working pits. During the excavation process, there are defects such as slow construction speed, irregular working pit size, high construction cost, excavators or manual excavation of working pits are easy to affect or even damage the completed working pits that are close to the distance, and the green seedling working pits need to be moved by machinery many times during construction, and the pit formation efficiency is not high.

[0003] Therefore, an adjustable street lamp foundation and seedling planting rapid pit forming device is studied to ensure that the working pit can be constructed continuously and accurately, which is of great significance for reducing the construction period of street lamp installation and seedling planting and improving construction efficiency. Summary of the invention
