Problems solved by technology

However, the accuracy of the box culvert jacking curve obtained by manual measurement is difficult to meet the requirements
Moreover, the use of labor is low in efficiency and has greater uncertainty
If there is a large displacement deviation during the jacking process of the box culvert, the construction has to be stopped to correct the deviation, but the static deviation correction takes a long time and is inconvenient to operate. If the control is not good, it is easy to cause deformation or cracks in the box

Abstract

The invention relates to a prefabricated box culvert jacking construction technology, in particular to an active deviation rectifying method and system for large-angle skew box culvert jacking construction. A reflecting prism target ball for tracking of a laser tracker is placed on the prefabricated box culvert, and a data processing subsystem analyzes the position of the reflecting prism target ball and judges the horizontal posture of the prefabricated box culvert during jacking according to the horizontal angle, the vertical angle and the slant distance between the laser tracker and the reflecting prism target ball; in the jacking process of the prefabricated box culvert, the data processing subsystem analyzes the obtained horizontal posture deviation value according to feedback information, the oil pressure amount of the jack is adjusted through the oil pressure adjuster, and active deviation correction of the prefabricated box culvert is achieved. According to the method, the dynamic displacement of the prefabricated box culvert can be tracked and measured in real time, high precision and high timeliness are achieved, and errors caused by subjectivity of people are avoided.

Description

technical field [0001] The invention relates to a prefabricated box culvert jacking construction technology, in particular to an active deviation correction method and a system for large-angle oblique box culvert jacking construction. Background technique [0002] In recent years, with the continuous development of the city, the urban area is expanding day by day. The railways built on the outskirts of the city have been sandwiched between the cities with the continuous expansion of the city, affecting the connection of the city's municipal roads. Under the condition of ensuring the normal operation of the original railway, to connect the urban areas on both sides of the railway into an organic whole, the construction method of the frame bridge jacking into the railway can be adopted. It has been proved by practice that this method will not damage the existing lines, but also ensure the normal construction of new projects, so it has been widely used. [0003] The main techn...
