Cast-in-place pile reinforcement cage hoisting and fixing device and construction method thereof

Abstract

The invention relates to a cast-in-place pile reinforcement cage hoisting and fixing device and a construction method thereof, and belongs to the field of building construction. According to the technical scheme, the cast-in-place pile reinforcement cage hoisting and fixing device is characterized by comprising a base, wherein the base is located above a pile hole used for containing a reinforcement cage and fixedly connected with the ground; the base is provided with a containing hole used for hoisting the reinforcement cage into the pile hole; the base is provided with a fixing assembly used for fixing the reinforcement cage; the fixing assembly comprises two abutting rods, the two abutting rods are symmetrically arranged in the direction of the center line of the pile hole; the length direction of the abutting rods is the same as the radial direction of the reinforcement cage; the abutting rods are in sliding connection with the base; and a driving device for driving the two abutting rods to get close to or away from each other is arranged between the abutting rods and the base. When two adjacent reinforcement cages are spliced, workpieces for clamping the reinforcement cages do not need to be detached, operation is easy, and the work efficiency is high.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a hanging and fixing device for a cast-in-place pile reinforcement cage and a construction method thereof. Background technique [0002] At present, in the pile foundation construction of bridges, high-rise buildings or high-speed railways, it is necessary to dig deep pile holes first, and then put a reinforcement cage in the pile holes and then pour cement to form a reinforced concrete structure. Because the pile holes are very deep, the reinforcement cages need to be fabricated in sections, and then lowered into the pile holes by a crane, and the main bars on the two reinforcement cages are manually screwed through the connecting sleeves to form a reinforcement skeleton. [0003] At present, in the related art, the existing Chinese patent with the notification number CN211080207U can be referred to, which discloses a long pile foundation reinforcement cage install...
