Pile position deviation real time detecting device

Abstract

The invention discloses a pile position deviation real time detecting device. The pile position deviation real time detecting device is characterized by comprising a main supporting rod, a first detecting rod and a second detecting rod. The length of the first detecting rod is the same with the length of the second detecting rod. A first sliding calibrated scale capable of stretching along the first detecting rod in the axial direction is arranged on the first detecting rod. A second sliding calibrated scale capable of stretching along the second detecting rod in the axial direction is arranged on the second detecting rod. A first elastic restoring mechanism is arranged between the first detecting rod and the first sliding calibrated scale. A second elastic restoring mechanism is arranged between the second detecting rod and the second sliding calibrated scale. An inclined angle with 45 degrees is formed between the first detecting rod and the main supporting rod. An inclined angle with 45 degrees is formed between the second detecting rod and the main supporting rod. An inclined angle with 90 degrees is formed between an extending line of the first detecting rod and an extending line of the second detecting rod. A relative location fixing mechanism is arranged among the main supporting rod, the first detecting rod and the second detecting rod. The pile position deviation real time detecting device has the advantages of being simple in structure, convenient to use and capable of observing the deviation value in real time. Staff are little. Detecting cost is low.

Description

technical field [0001] The invention relates to a construction detection device, in particular to a real-time detection device for pile position deviation. Background technique [0002] The coincidence of the geometric centroid of the pile position plane in the pile cap and the centroid of the horizontal section of the vertical force-transmitting member of the structure above is one of the basic rules of building structure design. The geometric centroid and the centroid of the horizontal section of the vertical force transmission member will not coincide, resulting in the fact that the load ratio actually distributed to each pile in the cap is inconsistent with the design condition, and the cap structure will generate additional internal forces such as bending moment and torque. If the pile If the deviation value of the position exceeds the specified value of the construction quality acceptance specification, it must be compensated by measures such as cap reinforcement and p...

AI Technical Summary

Problems solved by technology

[0003] 1. It is cumbersome to set up theodolites in the direction of the two axes perpendicular to the pile position. It is expensive to configure two theodolites and at least two surveyors at the same time.

[0004] 2. If the deviation of the pile driving process occurs on one of the two orthogonal axes, one of the surveyors will observe the pile deviation information, but another person needs to cooperate with the pile root to measure the deviation value with a ruler. This is both inconvenient and human error, and the probability of deviation in only one axis direction is not high

[0005] 3. When the pile sinking process generates deviation values ​​on two orthogonal axes at the same time, it is necessary to measure the deviation values ​​in two directions. The possibility of deviation measurement error is greater, and the deviation direction of the pile is not easy to obtain.

[0006] 4. If the circular cross-section pile is deviated, the accuracy of the deviation value of the measuring ruler is even more difficult to guarantee

[0007] 5. The possibility of errors caused by manual field measurement of deviation values ​​is high, and small deviation values ​​are not easy to find, nor can they continuously reflect deviation values, which affects the timely correction of pile position deviations in the pile sinking process
