Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a quick-connect device for drilling casings for foundation piles in building engineering. Background Technology

[0002] In deep foundation construction for building projects such as high-rise buildings, bridges, and subways, foundation piles are key components for bearing the loads of the superstructure. When the construction area has complex geological conditions such as loose soil layers, abundant groundwater, and a tendency for borehole collapse, casing wall protection technology is required. The casing needs to be extended section by section as the drilling depth increases, and quick-connect devices are necessary during this process.

[0003] Existing technology publication CN214330531U discloses a foundation pile drilling sleeve for building engineering, including a main body. The main body includes a sleeve, a hollow pipe, a rotating shaft, a tapered pipe, a cutting blade, and a threaded drill bit. Multiple fixing rods are arranged in a circular pattern on the upper part of the sleeve. One side of the fixing pipe is inserted into a groove, which is located inside a connecting block and is circularly distributed corresponding to the fixing rods. Through the cooperation of these components, this foundation pile drilling sleeve can easily complete drilling work using the cutting blade and threaded drill bit. The operation is simple and uncomplicated. The cutting blade and threaded drill bit greatly ensure the smoothness of the drilling arm, reducing the risk of collapse. The device has a simple structure and is easy to disassemble. Furthermore, when pouring is completed, the fixing rods above the sleeve can quickly and effectively remove the sleeve, greatly improving the efficiency of foundation pile drilling.

[0004] However, existing quick-connection devices for foundation pile drilling casings in construction engineering typically use welding or bolting for casing connection. This connection method suffers from low efficiency, complex operation, and insufficient connection reliability, making it difficult to meet the needs of high-efficiency construction. Therefore, we propose a quick-connection device for foundation pile drilling casings in construction engineering. Utility Model Content
