Device and method for detecting tilting degree of tubular pile

Abstract

The invention discloses a device and a method for detecting the tilting degree of a tubular pile. A command input unit is connected with a master control unit; a sensor unit is connected with a signal adjusting unit; an electronic compass in the sensor unit is directly connected with the master control unit; the electronic compass is connected with the master control unit; a temperature sensor is connected with the master control unit; the sensor unit is connected with the master control unit through the signal adjusting unit and an analog to digital (A / D) conversion unit; a display unit is connected with the master control unit; and a communication interface is connected with the master control unit. The method comprises the following steps of: A, self-checking the device; B, reading the electronic compass; C, sampling the acceleration speeds of an X-axis and a Z-axis; D, calculating the pitch angle according to the acceleration speeds of the X-axis and the Z-axis; E, sampling the acceleration speeds of a Y-axis and a Z-axis; F, calculating the roll angle according to the acceleration speeds of the Y-axis and the Z-axis; G; synthesizing a vertical tilting angle by using the pitch angle and the roll angle; and H, correcting the temperature compensation. The device is high in measurement accuracy, is convenient to operate quickly, and is economic and practical.

Description

technical field [0001] The invention relates to the field of foundation testing for geotechnical engineering, and more specifically relates to a device for detecting the inclination degree of prefabricated pipe piles, and at the same time relates to a method for detecting the inclination degree of prefabricated pipe piles, which is suitable for construction acceptance of prefabricated pipe piles. Background technique [0002] In foundation construction, pipe pile construction is the most basic and important step. Prefabricated piles are a method commonly used in pipe pile construction. Prefabricated piles are usually made in factories or construction sites. During construction, pile sinking equipment is used to drive, press or vibrate the piles into the soil. There are wooden piles, concrete piles, steel piles, etc., which are mainly used in China's construction field. There are two types of concrete piles and steel piles. Commonly used concrete piles include concrete soli...

Problems solved by technology

The domestic LS160 level is used to measure the angle between the surface of the level and the horizontal plane. Although the price is cheap, the accuracy is low and can only reach 0.1°, and it can only measure the vertical inclination angle B, not the horizontal azimuth A. In addition, its Using a segment digital tube to display the measurement results requires manual data recording, which increases the workload of the operator, so it is not suitable for pipe pile inclinometer work

The Swiss Leica D5 laser rangefinder has comprehensive functions, the main function is laser distance measurement, and it also has the function of inclinometer, which can be used to measure the angle between the surface of the instrument and the horizontal plane, and has analysis software, but it can only measure vertical The inclination angle B cannot measure the horizontal azimuth A, and the accuracy can only reach 0.1°, and its price is relatively expensive, and it is not a professional inclinometer tool, and it is not suitable for pipe pile inclinometer work.

In addition, none of the electronic inclinometer devices in the prior art has the report function, and the operator needs to manually compile the report, and the workload in the later stage is relatively cumbersome
