How to locate the reinforcing cage of cast-in-place pile in the construction industry now? What about the basic measures of routine positioning? The following is the related content of technical terms for positioning reinforced cage construction of bored piles compiled by Zhong Da Consulting, and the basic situation is as follows:

Zhong Da Consulting Company has compiled relevant data and information, and the basic contents of positioning the reinforcing cage of conventional cast-in-place piles are as follows:

For the positioning of the top of the skeleton, the length of the positioning rib must be calculated according to the measured orifice elevation, and the welding positioning must be carried out after repeated verification. Draw crosshairs on the reinforcing cage to find out the center of the reinforcing cage, and find out the center of the pile position according to the pile protection. When positioning the reinforcing cage, make the center of the reinforcing cage coincide with the center of the pile position.

Then insert two parallel square steel bars under the top lifting ring at the top of the positioning steel framework, and put two parallel sleepers on both sides of the casing to support the whole positioning framework on the sleepers.

Basic requirements for positioning reinforcing cage of cast-in-place pile;

The reinforcing cage is processed and manufactured in the steel bar processing plant and transported to the cofferdam platform. Each reinforcing cage will be made in sections according to the pile length. When making, strictly control the lap length and welding quality of the main reinforcement, and the adjacent main reinforcement in the same section is staggered. During installation, use hoist to cooperate with 20t crane. Due to the long skeleton and low bearing capacity of foundation, appropriate safety protection measures should be taken during hoisting and placing.

After placing the reinforcing cage, the upper opening shall be positioned according to the center line of the orifice and reinforced with φ 50 steel pipe to prevent the reinforcing cage from floating when pouring concrete.
