Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bored pile construction technology, especially to a high pile cap pile long casing pulling tool. BACKGROUND

[0002] High pile cap refers to the pile cap whose bottom surface is above the ground surface. When the high pile cap is constructed by using the pile column continuous pouring process, the reinforcement cage is once set in place, and the top of the reinforcement cage is sometimes 2-3m above the top surface of the protection cylinder. The high pile cap in soft soil areas needs to be set with a long protection cylinder, and the equipment for setting the long protection cylinder usually uses a driving and pulling machine. The driving and pulling machine uses a single-point hydraulic clamp to clamp the protection cylinder. The setting depth of the steel protection cylinder is sometimes 10-20m. After the pile body concrete below the ground is poured, the gap between the reinforcement cage at the top end of the protection cylinder and the wall of the steel protection cylinder is only 5-10cm. The hydraulic clamp is too large to be inserted into the gap between the reinforcement cage and the wall of the steel protection cylinder to clamp the protection cylinder. Therefore, an auxiliary tool must be used to hook the water outlet on one side of the top of the long protection cylinder to pull out the long protection cylinder.
