Movable automatic righting device for reinforcement cage and vibratory hammer and construction method of device

Abstract

The invention discloses a movable automatic righting device for reinforcement cage and vibratory hammer and a construction method of the device, relates to an auxiliary tool in the bored pile construction field and a construction method thereof, and aims to provide the movable automatic righting device for the reinforcement cage and the vibratory hammer and the construction method of the device, which have the advantage that the reinforcement cage can keep a vertical state under the vibration function of the vibratory hammer and then is implanted into a bored concrete pile. The automatic righting device for the reinforcement cage and the vibratory hammer comprises a vibratory hammer locator (1) and a sliding device (2); the sliding device (2) is mounted in a mode of sliding up and down; the vibratory hammer locator (1) comprises a vertically arranged sleeve (101) which is fixedly connected to the sliding device (2). The construction method for utilizing the automatic righting device for the reinforcement cage and the vibratory hammer comprises the following steps of (1) preparing; (2) lifting and aligning; (3) implanting the reinforcement cage.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to an auxiliary tool used in the field of cast-in-situ pile construction and a construction method thereof. Background technique [0002] In the field of cast-in-situ pile construction, the lifting and implantation of the reinforcement cage is an important construction link. For long spiral cast-in-place piles and two-way spiral soil-extruded cast-in-place piles, which include pouring concrete first and then planting bars, due to the resistance of cast-in-place concrete, it is very difficult to insert by using the gravity of the reinforcement cage, and the verticality is difficult. Guaranteed, therefore, the current process of pouring concrete first and then implanting cast-in-place reinforcement cages needs to be assisted by a vibrating hammer, and the reinforcement cage can be smoothly inserted into the designated position by vibrating the reinforcement cage. The vibratory hammer...

Problems solved by technology

For long spiral cast-in-place piles and two-way spiral soil-extruded cast-in-place piles, which include pouring concrete first and then planting bars, due to the resistance of cast-in-place concrete, it is very difficult to insert by using the gravity of the reinforcement cage, and the verticality is difficult. Guarantee, therefore, the current process of pouring concrete first and then implanting the reinforcement cage of the cast-in-place pile needs to be assisted by a vibrating hammer, and the reinforcement cage can be smoothly inserted into the designated position by vibrating the reinforcement cage

The vibratory hammer must loosen the steel wire rope hoisted above when it vibrates, but the following problem is: the vibratory hammer deviates due to lack of support, which makes the steel cage inserted into the pile body deflect, which seriously affects the pile quality of the cast-in-situ pile

This kind of construction quality problem is common in the pile foundation construction industry at present, and there is no mature technical solution so far
