Device and construction method for controlling verticality and azimuth of rectangular corbel piles

Abstract

The invention relates to a device used for controlling the perpendicularity and the azimuth angle of a rectangular bracket pile and a construction method. The device mainly comprises a main support, the main support is provided with a central hole, and one side of the main support is fixedly connected to a pile cylinder; a plurality of locating and adjusting units are arranged on the other side of the main support and respectively comprise a locating angular point, a leveling unit and a locating hole; the locating angular points, the leveling units and the locating holes are sequentially arranged from the outer edge of the main support to the center point of the main support; a horizontal alignment unit is arranged at the part, located on the same side as the locating and adjusting units, of the main support for guaranteeing the levelness of the main support; the pile cylinder is provided with rib plate clamping grooves and bracket clamping grooves; the rectangular bracket pile is clamped into the pile cylinder for being located. According to the device, through the new design, the perpendicularity and the azimuth angle of the prefabricated rectangular bracket pile are guaranteed in the construction process, and subsequent construction can be carried out smoothly.

Description

technical field [0001] The invention relates to the field of technical equipment related to underground engineering, in particular to a device and a construction method for controlling the verticality and azimuth of rectangular corbel piles. Background technique [0002] When the prefabricated component assembly structure is used in the underground project, it is necessary to measure and locate the perimeter of the prefabricated rectangular corbel pile in advance. The application of assembled structures in underground engineering has the following problems: [0003] 1. The press-fitting process of the prefabricated rectangular corbel pile structure cannot meet the verticality accuracy requirements. [0004] 2. The azimuth rotation of the prefabricated rectangular corbel pile structure cannot be effectively controlled. [0005] 3. The pile-forming process of large-scale prefabricated rectangular corbel piles in underground engineering cannot yet form the pile-pressing proce...

AI Technical Summary

Problems solved by technology

[0003] 1. The press-fitting process of the prefabricated rectangular corbel pile structure cannot meet the verticality accuracy requirements

[0004] 2. The azimuth rotation of the prefabricated rectangular corbel pile structure cannot be effectively controlled

[0005] 3. The pile-forming process of large-scale prefabricated rectangular corbel piles in underground engineering cannot yet form the pile-pressing process of assembled structure

[0007] 1. Pile planting process construction: soil is obtained by drilling holes, and then large-scale prefabricated equipment is used to guide the piles to the design depth; but in this method, when the prefabricated pile structure sinks to a certain depth below the ground, the verticality of the pile position, The azimuth angle cannot be effectively controlled and cannot meet the requirements of the prefabricated assembly structure;

[0008] 2. Steel sleeves are used to control the verticality of the pile structure; however, the steel sleeves in this method have a certain hindrance to the drilling and grouting, and cannot be recycled and reused, resulting in waste. In addition, the existence of the steel sleeves makes the assembled structures unable to proceed
