Description

Technical Field

[0001] The invention relates to the technical field of pile foundation hole fixing, and in particular to a pile foundation hole fixing device for building pile foundation construction and a construction method thereof. Background Art

[0002] At present, when constructing pile foundations at a construction site, the position of the pile foundation must first be marked on the ground, and then a pile foundation hole is opened at the marked position. The pile foundation hole is opened using a drilling machine. After the pile foundation hole is opened, the pile foundation is driven into the pile foundation hole by a pile driver, thereby completing the pile foundation construction work.

[0003] When using the existing pile foundation hole positioning device, it is necessary to manually mark the ground with white powder circular marks, which will result in a certain degree of deviation and error. Manual marking is difficult to achieve high-precision positioning requirements, especially in large or complex construction sites.

[0004] Therefore, we make improvements on this and propose a pile foundation hole fixing device for building pile foundation construction and a construction method thereof.

[0005] After searching, relevant patents have been published, with publication number: CN 217150231 U, patent name: A device for fixing pile foundation holes in pile foundation construction, applicant: Wuhan Surveying and Exploration Research Institute Co., Ltd. of MCC Group. This patent provides a device for fixing pile foundation holes in pile foundation construction. The fixing device includes a frame with a positioning hole and a positioning cylinder installed at the positioning hole of the frame, the positioning cylinder includes a cylindrical shell, a servo motor located at the top of the cylindrical shell and a positioning mechanism located inside the cylindrical shell, the positioning mechanism includes a threaded rod connected to the output shaft of the servo motor, a positioning sleeve threadedly connected to the threaded rod and a scraper plate arranged at the bottom end of the threaded rod, a limiting slide is vertically provided on the inner wall of the cylindrical shell, the outer wall of the positioning sleeve is embedded in the limiting slide through a slider, and when the servo motor drives the threaded rod to rotate, the slider on the outer wall of the positioning sleeve slides up and down along the limiting slide; the outer diameter of the scraper plate matches the inner diameter of the positioning sleeve. The pile foundation hole positioning device provided by the utility model can scrape off the soil adhered to the positioning cone, so that it is convenient for external personnel to use the positioning cone and achieve the corresponding positioning effect.
