AI Technical Summary
Conventional methods for connecting steel pipe sheet pile joints face issues such as soil entering the joint pipes during driving, leading to improper engagement, reduced accuracy, and potential detachment or breakage, along with uneven compartment sizes complicating cleaning and filling processes.
A method involving a tubular leading joint member with a high-pressure water injection nozzle at its lower end, controlled water pressure based on driving angle measurement, and vertically oriented slits to engage with a trailing joint member, ensuring soil removal and maintaining verticality during driving, with communication openings for effective cleaning and filling.
The method reduces penetration resistance, improves driving accuracy, prevents joint detachment, ensures thorough cleaning, and facilitates reliable mortar filling, thereby enhancing the connection process of steel pipe sheet pile joints.
