Abstract

The invention provides a contraction positioning support for determining the center position of a pile foundation. The contraction positioning support is arranged in a pile opening of the pile foundation and comprises a center base plate located in the middle portion of the pile opening, and a plurality of telescopic arms located in the different directions and horizontally arranged, and a plumb bob is hung in the center position of the center base plate. Each telescopic arm comprises a first connecting end and a second connecting end. The first connecting ends of the telescopic arms are connected to the center base plate, and the second connecting ends of the telescopic arms are connected to the pile opening. The problem about how to determine the positions of the pile centers of pile foundations with different pile diameters through the same positioning structure is solved, and the positioning construction accuracy and efficiency are further improved.

Description

technical field [0001] The invention relates to a shrinkable positioning bracket, in particular to a shrinkable positioning bracket for determining the center position of a pile foundation and a construction method thereof. Background technique [0002] At present, in the construction of pile foundations in domestic construction sites, the determination of the core position of bored piles is different between small pile diameter pile foundations and large pile diameter pile foundations. in: [0003] The small pile diameter pile foundation mainly adopts the arrangement of wooden squares on the top of the pile mouth. The design position of the pile center is determined by setting out the position of the pile center of the pile foundation on site with a total station, and then the outer contour of the pile is measured to the position of the pile center point by a steel tape measure. According to the distance measurement, the offset of the position is judged according to the ob...
