Description

Technical Field

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

[0002] During the construction of pile foundation, pile position positioning measurement has always been the focus of construction site control, especially the impact drilling method, which is often prone to pile position deviation due to disturbance of construction machinery or other uncontrollable factors, so we need to conduct positioning re-measurement from time to time during the construction process. The re-measurement of the existing technology is generally done by bridging a cross-shaped springboard on the pile hole casing, and then manually setting up a prism assembly, and then using a total station to cooperate with the prism assembly to lay out the position of the pile hole design center, and then using a measuring ruler such as a tape measure to measure the deviation between the pile hole design center and the actual center of the pile hole casing; finally, the displacement correction is performed on the pile hole casing that has been deviated until the re-measured deviation is within the set tolerance range. However, this method has a large safety hazard, especially for pile holes with a large diameter (more than 1m), there is a risk of falling off the pile hole when people go up to the springboard to perform the prism assembly layout operation; and the deviation needs to be measured by a measuring ruler such as a tape measure in the future, which is inefficient; and the manual ruler has a large error.
