Abstract

The present invention provides a measuring device and a method of dynamic real-time measurement of position and posture of a pipe pushing jack, wherein the method comprises the steps of setting a total station and a rear view prism inside a starting shaft to obtain laser target coordinates by the total station and obtain the pipe pushing jack coordinates by the laser target coordinates, an azimuth angle, a rolling angle, and a pitch angle; installing a forward-looking prism on the pipe joint to obtain a tunnel path line; moving the total station onto the pipe joint to back calculate the real-time coordinates of the total station by the path line, and measure the position and posture of the pipe pushing jack real timely; moving the rear view prism onto the pipe joint to back calculate the real-time coordinates of the rear view prism by the path line, and measure the position and posture of the pipe pushing jack real timely. The device comprises a laser target located on the pipe pushing jack; a forward-looking prism installed on the pipe joint inside the tunnel; a forward-looking prism, a total station, and a rear view prism placed in order behind the laser target; and a controller connected with the laser target. The present invention is able to solve problems of uneasy measurement of the position coordinates caused by dynamic changes with the pipe joint moving to the pipe pushing jack.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a measuring device and method for dynamically and real-time measuring the position and attitude of a pipe jacking machine. Background technique [0002] Pipe jacking tunneling technology is an engineering construction technology of underground excavation. It is developed with the development of modern underground engineering, transportation, municipal construction and electrical communication facilities. It is used in water conservancy, water supply and irrigation projects. The new technology of laying, the use of pipe jacking technology can eliminate the need for open excavation when the pipeline crosses roads and rivers, and will not cause any impact on road traffic and river discharge during the construction process. The pipe-jacking tunneling technology has the advantages of high degree of automation, saving manpower, and fast construction speed, and can control ground...
