Abstract
Description
Technical Field
[0001] This utility model relates to the field of square drill bit technology, and in particular to a fixed square drill bit. Background Technology
[0002] Anti-slide square piles play a crucial role in landslide control and other engineering projects. They utilize the resistance (anchoring force) of the piles in the stable strata below the sliding surface to balance the thrust of the landslide mass, thereby improving the stability of the landslide. When a landslide occurs, anti-slide piles can effectively prevent sliding and promote the stabilization of the landslide mass in front of the piles. Currently, based on factors such as the thickness of the landslide mass, thrust, waterproofing requirements, and construction conditions, cast-in-place concrete square piles are primarily used for construction.
[0003] However, in actual construction, existing construction tools have many drawbacks in the process of excavating holes to prepare square piles, such as low excavation efficiency, insufficient hole accuracy, and poor adaptability to different geological conditions, which affect the progress and quality of anti-sliding square pile construction. Therefore, we propose a fixed square drill bit to solve the above problems. Utility Model Content
