Description

Technical Field

[0001] The utility model belongs to the technical field of cast-in-place pile cleaning equipment and relates to an electric handheld special hole cleaning device for bored cast-in-place piles. Background Art

[0002] With the national "dual carbon" strategic goal, my country has begun to accelerate the construction of a "new power system with new energy as the main body", and the new energy photovoltaic industry has achieved a new round of rapid development. As a pillar industry of new energy, photovoltaic engineering is characterized by short construction period, large photovoltaic construction area, large number of pile foundations, and large labor input. In particular, if the foundation of land photovoltaic engineering is constructed by bored cast-in-place piles, there must be a situation of multi-pile group foundation construction. After the large-scale drilling and rotary drilling equipment completes the pile foundation hole operation in batches, it is necessary to notify the owner and the supervisor for acceptance before the pile foundation pouring operation can be started. After the bored cast-in-place pile is bored, it is restricted by factors such as the batch bored pile hole acceptance time and concrete supply capacity. Secondary hole cleaning must be carried out before actual pouring. If the drilling and rotary drilling equipment is used for hole cleaning, the large-scale drilling and rotary drilling equipment will be slow to transfer and the heavy equipment will be disturbed after moving in the hole construction area, resulting in incomplete secondary or multiple hole cleaning. At the same time, it is not economical to use large-scale drilling and rotary drilling equipment for secondary hole cleaning. The efficiency and economic rationality of the hole cleaning process during the photovoltaic project pile foundation directly affect the cost of project implementation. Although there are many hole cleaning equipment available, there are only a few special, simple and portable hole cleaning tools that are truly suitable for photovoltaic projects.

[0003] Land photovoltaic projects have unique construction layout characteristics: densely packed piles, large numbers, short pile lengths, and basically consistent pile diameters within a project construction area. Traditional large-scale drilling and rotary drilling equipment cannot solve the corresponding problems in one go for secondary hole cleaning. Multiple hole cleanings are required, which is uneconomical and unreasonable. In addition, the secondary transfer causes many disturbances to the existing holes and is inefficient.

[0004] In summary, the existing technology has the problems of low cleaning efficiency and poor applicability. Utility Model Content
