Description

Technical Field

[0001] The utility model relates to the technical field of building construction measurement devices, in particular to a pile hole deviation measuring ruler component. Background Art

[0002] During the construction of pile foundations, pile position positioning and measurement has always been the focus of on-site control, especially for the impact drilling method. It is often easy for the pile position to deviate due to disturbances caused by construction machinery or other uncontrollable factors, so we need to conduct positioning re-measurements 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. The position of the pile hole design center is then laid out using a total station in conjunction with the prism assembly. The offset between the pile hole design center and the actual center of the pile hole casing is then measured using a measuring tape or other measuring ruler. Finally, the offset pile hole casing is shifted and corrected until the re-measured offset 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 on the springboard to perform the prism assembly layout operation. The offset needs to be measured using a measuring tape or other measuring ruler later, which is inefficient. The manual setting of the ruler also results in large errors.

[0003] Therefore, there is an urgent need to provide a device that can cooperate with a total station to complete pile hole deviation measurement, so as to improve construction safety, construction efficiency and detection quality. Utility Model Content
