Pile foundation reinforcement cage elevation and centering positioning device and method

Abstract

The invention provides a pile foundation reinforcement cage elevation and centering positioning device and method, and relates to the technical field of pile foundation construction. The pile foundation reinforcement cage elevation and centering positioning device comprises a limiting base, a positioning ring and an elevation rod, a circular through groove is formed in the middle of the limiting base, and a boss extends from the groove wall of the circular through groove; positioning rods are evenly distributed on the positioning ring in the circumferential direction of the positioning ring, avertical laser emitter is arranged at the intersection point of a cross in the positioning ring, and fastening assemblies are evenly distributed on the positioning ring in the circumferential direction of the positioning ring; a threaded column and a threaded sleeve are arranged at the two ends of the elevation rod correspondingly, the elevation rod is provided with a first scale marking line, and the elevation rod is connected with the positioning ring through the fastening assemblies; and under the condition that the positioning ring is placed in the circular through groove of the limitingbase, the end of each positioning rod abuts against the groove wall of the circular through groove. According to the pile foundation reinforcement cage elevation and centering positioning device and method, the elevation and centering positioning precision and speed during reinforcement cage installation are improved, the pile foundation reinforcement cage elevation and centering positioning device and method can be repeatedly used and are environmentally friendly, and the construction cost is saved.

Description

Technical field[0001]The present invention relates to the field of pile foundation construction, in particular to a pile foundation reinforcement cage high and a pair positioning apparatus and method.Background technique[0002]The pile foundation is a very important part of the structural force system, and the importance of its construction quality is self-evident. Whether the central offset of the pile foundation is within the specification range is the primary standard for judging whether a pile foundation is qualified. The steel cage installation is an important step in the construction of the drilling pile. If the pile foundation steel cage installation center point is too large, it will cause the pile foundation to produce an eccentricity of the pile foundation to reduce the capacity of the pile foundation, and there is a very large Quality hidden; if the reinforced cage is not accurate, in order to ensure that the surface of the steel cage is satisfied with the longitudinal ste...
