Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a pile center positioning device. Background Technique

[0002] The existing pile center positioning devices are mainly "cross" protection piles. The center position of the pile is checked by the way of cross alignment of the top guy wires, or the position of the pile center is accurately lofted by measuring instruments. The characteristics of the two methods are as follows:

[0003] 1. Cross guy wire alignment: The advantage is that the alignment is carried out by the temporarily set protection piles through guy wires, without the need for measuring point lofting each time, which is beneficial to the frequent recheck of the pile center and saves time; the disadvantage is that the accuracy is relatively poor, and it is easy to shift, and the guy wires are often damaged; specifically, the cross guy wire alignment is a fixed recheck. However, due to improper protection of the guy wires and the like during the construction process, the guy wires will be damaged or the set protection piles will be displaced, resulting in inaccurate temporary alignment data. If it is not found in time during the construction process, the center of the bored pile will be displaced finally.

[0004] 2. Measurement lofting: The advantage is that the measurement accuracy is relatively high and the data is more accurate; the disadvantage is that the centering recheck of the reference point is required for each measurement lofting, and the recheck time for each time is relatively long, which is not convenient for the frequent recheck during the pile foundation construction process; specifically, the measurement lofting is a mobile recheck, that is, through the existing reference point positions, after calibration through turning measurement or encrypted temporary reference points, accurate lofting recheck is carried out by a theodolite. However, due to the bulky instrument, calibration recheck by means of the existing reference point positions is required each time, and the operation difficulty and technical requirements are relatively high. The pile foundation construction workers basically cannot operate, and at least two or more people are required to complete this work, which seriously affects the recheck during the drilling process and the timeliness cannot be guaranteed.

[0005] Based on the above situation, there is an urgent need for a pile center positioning device that can not only improve the positioning efficiency of the pile center but also ensure the positioning accuracy of the pile center. Content of the Utility Model
