Problems solved by technology

[0003] In pile foundation construction, the upper and lower well-shaped frames are usually used to guide the steel casing of the pile foundation. The upper and lower well-shaped frames need to be erected above the hole. The temporary structure requires a large amount of work and occupies a large area, which is not convenient for construction personnel to operate and affects the construction progress. , and the diameter of the guide frame is small in scope of application

Abstract

The invention discloses a guiding and positioning device and method for land large pile foundation permanent steel protecting cylinders, and belongs to the field of architectural construction. The device comprises a positioning frame, positioning modules and limiting plates, wherein four positioning modules are provided; the positioning modules are arranged in the center positions of the side edges of the positioning frame, and can extend; the limiting plates are arranged at the end parts of the positioning modules in directions perpendicular to the length directions of the positioning modules; the limiting plates are arranged near the center of the positioning frame; and the center connecting lines form a circular structure to position and fix placed permanent steel protecting cylinders.The device has the following advantages: when the placing precision of the steel protecting cylinders is guaranteed, temporary structures are few in material and small in occupied land; constructors are convenient to operate; the placing efficiency of the steel protecting cylinder is improved; the transfer usability is high; and the adjustment can be performed according to the sizes of the protecting cylinders to achieve wide application range.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a guiding and positioning device for a permanent steel casing of a large-scale pile foundation on land and a method thereof. Background technique [0002] With the development of traffic construction in our country, it is inevitable to build bridges in high earthquake areas. In order to improve the seismic performance of foundations, steel casing pile foundations are generally designed. Large-diameter super-long steel casing pile refers to adding a permanent steel casing with the same diameter as the pile foundation in the range below the top surface of the pile foundation, and welding steel bars and grouting pipes on the outside of the steel casing to align the hole wall with the pile foundation. The gap between the outer walls of the steel casing is reinforced by grouting to improve its seismic performance. During the construction of this type of pile foundation,...
