Description

Technical Field

[0001] This utility model relates to the field of spiral steel pile pre-hole technology, and in particular to a spiral steel pile pre-hole construction device. Background Technology

[0002] In the field of pre-drilling for spiral steel piles, the operational accuracy and continuous operation capability of the equipment directly determine the construction efficiency and the quality of steel pile installation. While current pre-drilling equipment can complete foundation drilling, it still has significant technical shortcomings in terms of leveling adaptability to complex terrain and cleaning and maintenance of the drill bit, making it difficult to meet the demands for efficient and precise construction.

[0003] First, traditional leveling structures suffer from poor adaptability, resulting in low accuracy and efficiency. Existing devices mostly employ manual mechanical leveling (such as adjusting the support legs with bolts). Adjustment requires turning each support leg individually, relying on manual observation of a level to determine the level. On uneven outdoor sites (such as gentle slopes or raised areas of the foundation in photovoltaic power stations), even a 2-3° slope requires repeated adjustments 3-5 times, with each leveling cycle often exceeding 5 minutes, leading to extremely low efficiency. More importantly, the accuracy of manual adjustment is heavily influenced by operator experience. The thread clearance of the screw can easily cause the frame to remain tilted by more than 0.5° after leveling, resulting in a vertical deviation of the auger drill rod exceeding 1° / m, causing misalignment of the pilot hole. This necessitates secondary hole repair during subsequent steel pile installation, severely slowing down the construction progress. Second, the drill head cleaning structure design is unreasonable, leading to significant soil adhesion problems. During pilot hole drilling, the drill bit (including the conical drill bit and helical blades) of the auger drill rod will accumulate a large amount of mud (especially in clayey soil). Existing cleaning methods either rely on manual cleaning afterward (which requires stopping the machine for disassembly, which is time-consuming and labor-intensive) or only have a single flushing port at the top. The top flushing port can only flush the upper part of the blades, while the sides of the drill bit (the junction between the blade and the drill bit, and the sides of the blades) are the hardest areas for mud accumulation. If the mud in these areas is not cleaned in time, it will form hardened clumps: on the one hand, it increases the cutting resistance of the next drilling, causing the drive motor load to increase by 15%-20%, and aggravating the wear of the drill bit; on the other hand, when the clumps of mud fall off, they can easily jam the blades, and even cause the drill rod to rotate unbalanced, causing the device to vibrate and affecting the straightness of the pilot hole.
