A pile body verticality detection device

Abstract

The invention discloses a pile body verticality detection device, which is used for measuring the verticality of the pile body, and comprises a main body, a telescopic rod, a dial, a pointer, and a card slot. The main body is a straight rod; the telescopic rod is arranged on the top of the main body; Set on the top of the telescopic rod, the pointer is parallel to the telescopic rod and does not overlap; the dial is suspended on the pointer through a pull rope, and the dial is provided with an angle scale line, and the scale lines on the dial are arranged in a circular ring, and the lanyard The connection point with the pointer is the center of the circle of the scale line; one card slot is provided on the sides of the two ends of the main body, and the card slot is provided with a groove parallel to the main body. The device can be used to detect the verticality of underwater piles, avoiding the limitations of conventional verticality detection methods, and avoiding the influence of on-site water flow, water quality, wind and other environmental factors on the measurement results; the device can measure the verticality of piles above the ground Detection, simple operation, high work efficiency, accurate measurement.

Description

technical field [0001] The invention relates to the technical field of engineering construction testing equipment, in particular to a pile verticality testing device. Background technique [0002] Pile driving is often required in the construction process of real estate construction, highway construction, railway construction, port wharf construction, airport construction and water engineering construction. In order to ensure the quality of the project, the verticality of the pile body needs to be detected during the piling process and after the piling is completed. , the existing pile verticality detection technology includes: total station observation method, laser plummet observation method and vertical line method. [0003] (1) Total station observation method [0004] Set up a total station on the opposite side and side of the piling machine, and the two observation lines are parallel and perpendicular to the axis of the piling manipulator, and pass through the trimmin...

AI Technical Summary

Problems solved by technology

[0010] The existing technology applied to the verticality detection of underwater piles mainly has the following problems: 1. The construction buoy platform has a small space and is easy to shake, so it is difficult for the total station to be stably fixed on the buoy platform; The operation of the method is complicated. The vibration of the pile body and the shaking of the buoy during piling will affect the accuracy of the laser plummet. The underwater pile body is difficult to realize due to the low visibility in the water and the refraction interference of impurities in the water; 3. The vertical line method Easily affected by wind and water flow, the accuracy is difficult to control, and the measured value is inaccurate

In addition, due to the large number of piles, if the verticality of the piles is detected by the total station observation method, the laser plummet observation method and the vertical line method, the operation is cumbersome and repeated measurements are required, which increases the construction cost
