Description

Fine adjustment system for oral workpieces
Technical Field

Background
In order to improve the passing convenience and efficiency of people and reduce the influence on the existing buildings and traffic, tunnel construction of underground space is used as a capital construction project, the country is always vigorously developing subway tunnel construction in cities, the diameters of the tunnels are different, as is well known, a common subway tunnel runs in two directions and is divided into two lines for construction under the condition that early tunneling equipment and a construction process are deficient, and the diameter of the common tunnel is smaller and is about 4 meters. As the level of tunnelling equipment and associated construction technology increases, large diameter shield tunnelling machines (e.g. greater than 10 metres) are manufactured, along with corresponding kit and construction methods. Compared with a common tunnel, the large-section shield tunnel is mostly a single-hole double-line tunnel and needs to be designed with an internal structure.
The construction of the internal structure after the tunnel is communicated has great influence on the construction period, cost and construction management. Therefore, in recent years, the construction of the internal structure of the large-section shield tunnel adopts the prefabricated square-shaped member assembling trolley and the synchronous construction method so as to solve the problem that the shield tunneling and the internal structure cannot be synchronously constructed during square-shaped member assembling. The shield machine is propelled, and the rear part adjusts the posture of the square pieces through the assembling trolley to realize the assembling of each section of prefabricated square pieces.
In order to ensure that the structure assembled by the prefabricated square characters meets the requirements of structural safety and use functions, the assembling precision of the prefabricated square characters must be ensured. Namely, after the prefabricated square characters are assembled, the positions and postures of the prefabricated square characters accord with the design requirements. Therefore, after each prefabricated square member is assembled, the prefabricated square members are measured, and whether the position deviation and the posture deviation meet the requirements or not is checked.
At present, the axis relation between the square-shaped parts is judged by means of naked eyes of workers, the error is large, the assembling efficiency is low, the problem of the installation aspect of the follow-up tunnel is caused by the large error of the axis relation between the square-shaped parts, and the later operation and use of the tunnel are seriously influenced.
