Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic construction technology, specifically relating to a hole cleaning device for mountain photovoltaic grouting piles. Background Technology

[0002] With the increasing number of photovoltaic power plants, land resources with favorable construction conditions are gradually becoming scarce. In order to continuously respond to the national dual-carbon goals, photovoltaic projects are beginning to expand into mountainous areas, tidal flats, and deserts, especially in provinces like Yunnan and Inner Mongolia, which have abundant sunshine throughout the year and low population density. As long as the limitations of terrain are overcome through reasonable technology, the development potential of photovoltaic and other new energy sources will be enormous. This will not only improve energy efficiency and effectively utilize land resources, but also drive rural revitalization through the photovoltaic industry, thus contributing to the healthy and orderly development of the photovoltaic industry.

[0003] Mountainous photovoltaic projects are characterized by uneven terrain, steep slopes, significant geological variations, complex topography, and inconvenient transportation. Pile foundation construction, as a high-intensity, resource-intensive, and terrain-dependent sub-project, hinges on its speed and quality, which directly impacts the project's success. Currently, pile foundation construction in mountainous photovoltaic projects frequently suffers from quality issues such as insufficient effective pile length, slag inclusions in the pile body, and necking, leading to insufficient pile bearing capacity and even pile breakage.

[0004] An investigation of currently under-construction bored piles revealed that the primary cause of pile quality defects in mountainous photovoltaic projects is borehole collapse. Due to terrain and technical factors such as steep slopes, uneven terrain, and the difficulty of operation with small pile foundation boreholes, workers often resort to clay tools like shovels and spoons after pile foundation collapse. This not only results in low efficiency and high manpower consumption for cleaning the boreholes but also yields unsatisfactory results, making borehole collapse a persistent problem in the quality of pile foundation engineering in mountainous photovoltaic projects. Therefore, it is necessary to design a borehole cleaning device for mountainous photovoltaic bored piles to address these issues. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a hole cleaning device for mountain photovoltaic cast-in-place piles. The device is easy to operate and carry, which can further improve the hole cleaning efficiency of collapsed pile foundations, save human resources, and ensure the construction quality of pile foundations in mountain photovoltaic projects.

[0006] To achieve the above design, the technical solution adopted by this utility model is as follows:

[0007] A hole-cleaning device for mountain photovoltaic cast-in-place piles includes a connecting rod, a handle with a horizontal bar structure connected to the top of the connecting rod, and a cutting mechanism connected to the bottom of the connecting rod.

[0008] Preferably, the cutting mechanism includes two semi-circular plate-shaped cutting blades.

[0009] Preferably, the curved edge of the cutting blade is connected to a curved baffle.

[0010] Preferably, the straight edge of the cutting blade is welded to the bottom of the connecting rod.

[0011] Preferably, the two cutting blades are inclined together to form an angle of 20° to 25°.

[0012] Preferably, the diameter of the cutting mechanism is smaller than the diameter of the pile foundation hole.

[0013] Preferably, the surface of the connecting rod is provided with graduations.

[0014] The beneficial effects of the above-mentioned hole cleaning device for mountain photovoltaic cast-in-place piles are as follows:

[0015] This device can be used for dry-drilled cast-in-place pile cleaning in a simple and efficient manner, and can also be used as a simple device for measuring hole depth and diameter. It is easy to manufacture, portable, easy to operate, and efficient in cleaning holes. Operators are happy to use it, which can effectively improve the quality of pile foundation hole cleaning.
